Description
Technical Field
The present disclosure relates to electric ground compactors, such as plate compactors and rammers, for construction work.
Background
Good compaction is the basis of any construction work. It increases load carrying capacity and durability and prevents soil settlement and damage by frost and water erosion. Different machines for ground compaction are known, such as roller compaction rollers, rammers and vibrating plate compactors.
These compacting machines are traditionally powered by internal combustion engines, but electrical machines are now being introduced into the market. For example, US10,344,439B2 discloses an embodiment of an electric plate compactor. EP 1267001B1 discloses a further embodiment of an electric plate compactor and US 9,175,447B2 shows an electric ram.
Importantly, the ground compacting machine is well balanced and has the ability to operate for long periods of time. It is also important that the machine handling does not involve any time consuming maintenance tasks and that the compactor is easy to use in an efficient manner.
Existing electric compactors require modification to take full advantage of their potential.
Disclosure of Invention
It is an object of the present disclosure to provide an improved electric ground compactor that is easy to use and is capable of long term operation.
This object is at least partly achieved by an electric ground compactor for compacting a ground during a construction work. The ground compactor includes an upper mass movably connected to a lower mass, wherein the lower mass is arranged to contact the ground during compaction. The ground compactor includes at least one motor arranged to operate within a range of voltages to drive the ground compactor. The ground compactor further includes: at least a first battery compartment and a second battery compartment for receiving respective first and second batteries; and a power circuit configured to supply electric power within the voltage range from the first battery or the second battery to the at least one motor.
Thus, a ground compactor having an expanded battery capacity is provided. However, instead of a larger battery, it is sufficient that the floor compactor comprises two separate batteries that can be used independently of each other, i.e. that one battery is inserted into the battery compartment in order to operate the floor compactor. This simplifies handling, as each cell has a reasonable weight. The battery may also be removed from its compartment, for example for charging, and the ground compactor may be operated by a single battery at the same time. In this way, the operator can maintain the ground compacting operation even during charging of one of the batteries.
According to various aspects, the motor has a center of mass lying in a first plane, wherein the respective geometric centers of the battery compartments are separated from each other by the first plane. In this way, the motor is located between the battery compartments, which provides increased stability to the floor compactor and also simplifies routing of the wire bundles. Advantageously, each battery is individually connected to the drive circuit of the motor, so that the floor compactor can be operated as long as at least one battery is inserted into the battery compartment.
According to various aspects, the motor is arranged to operate continuously during removal and/or insertion of one of the first and second batteries, provided that the other of the first and second batteries is received in its corresponding battery compartment and has a minimum charge level. This means that the ground compactor implements a "hot plug" feature in which an operator can insert and remove batteries during ground compaction, which is advantageous in some operating scenarios. Advantageously, the motor drive circuit draws power from one battery at a time, which means that one battery is depleted and chargeable at a time while the other battery remains fully charged.
According to various aspects, the motor is arranged to drive an eccentric weight mechanism comprised in the lower mass via a drive belt. These mechanisms are well tested and provide a reliable means for driving the ground compactor.
According to various aspects, the first battery compartment and the second battery compartment are integrally formed in a battery housing, wherein the battery housing is assembled in the upper mass via at least one vibration isolation element. This may better protect the battery from the external environment, in particular from potentially damaging vibrations generated during ground compaction.
According to aspects, the battery housing comprises a first battery compartment and a second battery compartment arranged to cover the first battery compartment and the second battery compartment, respectively. These covers provide additional protection to the external environment. The cover may include a lock to prevent the cover from opening. In this way, the battery inserted into the battery compartment can be protected from theft. The lock may be implemented as a combination lock or an electronic lock, without the need for a physical key.
According to various aspects, the battery housing includes a control panel arranged to be accessible to an operator for controlling at least a portion of the power circuit. The control panel may advantageously be positioned between the first battery compartment cover and the second battery compartment cover. The control panel forms part of a control unit 160. The control panel may advantageously be arranged to control a lock on the battery compartment cover.
According to various aspects, the fan is mounted on a shaft of the motor so as to be driven by the motor and is arranged to provide a flow of cooling air into the first battery compartment and the second battery compartment. The cooling air flow is optionally configured to initially extend from the air inlet along the direction of extension of the motor shaft, and subsequently form a branching flow from the motor shaft radially outwards towards the first battery compartment and the second battery compartment. The advantage is that the same fan can be used to cool both batteries during use.
The fans may be of different types, but radial fans as illustrated in fig. 3 and 4 are preferred. The radial fan may advantageously be configured to also provide a cooling air flow for cooling the motor.
According to various aspects, a ground compactor includes: a base plate arranged to contact the ground; an engine plate assembled on the base plate through a first set of vibration isolation elements; and a battery plate assembled on the engine plate by a second set of vibration isolation elements, wherein the motor is mounted on the engine plate and wherein the battery plate is arranged to support the first battery compartment and the second battery compartment. Together, the two sets of vibration isolation elements provide sufficient vibration isolation that protects the battery from vibrations generated during use of the ground compactor. The two sets of vibration isolation elements cooperate to achieve such high levels of vibration isolation. Another advantage of having two sets of vibration isolation elements is that the oscillating behaviour of the two masses is suppressed.

Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which certain aspects of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments and aspects set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.
It is to be understood that the invention is not limited to the embodiments described herein and shown in the drawings; rather, the skilled person will recognize that many variations and modifications are possible within the scope of the appended claims.
FIG. 1 illustrates an exemplary ground compaction apparatus 100. This particular ground compaction device is commonly referred to as a plate compactor. Another exemplary ground compaction apparatus 600, commonly referred to as a ram, is shown in fig. 6. At least some of the solutions discussed herein are applicable to both types of compactors.
Ground compactors are used to prepare the ground for various types of construction work, such as construction of buildings, and laying of pipes and roads. Compactors, such as the exemplary plate compactor 100 of fig. 1 and the exemplary ram 600 of fig. 6, are conventionally powered by gasoline engines. In this case, the operator may fuel the compactor by filling the gas tank on the machine, and then may operate the machine for a relatively long period of time until the gas tank must be refilled again. The machine generally does not need to be stopped during refueling, which may be particularly advantageous in the case of compacting viscous materials, which might otherwise adhere to the floor contacting the ground.
The ground compactor 100, 600 optionally includes a control unit 160 arranged to control various functions of the ground compactor. The control unit 160 may be connected to or included as part of a control panel of the ground compactor.
Electric compactors (such as the embodiment provided in US10,344,439B2) instead use electric power to drive the machine. A disadvantage of electric machines is that the batteries need to be recharged regularly. Thus, large batteries are typically used in order to provide the durability required for extended duration operation. However, such large batteries tend to be heavy and difficult to handle, and are not easy to transport. Battery charging requires an external power source that is generally not conveniently directly accessible from the operating location, meaning that the battery needs to be transported from the machine at the operating location to the location of the charging device. This can be problematic if the battery is very heavy.
The present disclosure relates to a compactor having the ability to operate for extended durations, wherein battery handling has become more convenient. This is achieved by providing two battery compartments for receiving corresponding batteries of the same type. The machine may be driven by any of these batteries, which means that the operator may remove one battery for charging and still use the remaining battery to operate the machine. By providing two batteries, an extended operating time is obtained. However, each battery is associated with a manageable weight and form factor, allowing for convenient manual handling by an operator. An operator who wants to perform a smaller work task requires only one battery.
Referring to fig. 1 and 6, disclosed herein is an electric ground compactor 100, 600 for ground compaction during construction work. The ground compactor includes an upper mass 110, which upper mass 110 is movably connected to a lower mass 120 disposed below the upper mass 110 when the machine is in use (i.e., closer to the ground). The lower mass 120 is arranged to contact the ground during compaction. For a plate compactor, the lower mass may include, for example, a base plate and a vibrating element, while for ram 600, the lower mass includes a tamper foot.
Compactor 100, 600 is associated with a corresponding forward direction F, where the forward direction is the direction in which the machine is normally moving during use. An upward direction on the machine is herein interpreted as a direction away from the ground during use, as indicated in fig. 1 and 6. Likewise, the downward direction of the machine is opposite to the upward direction. During normal operation, an operator is located behind the machine to hold the handle 170 and push the machine in the forward direction F.
The ground compactor 100, 600 includes at least one motor 210, the at least one motor 210 being arranged to operate within a voltage range to drive the ground compactor 100, 600. Typically, the battery and motor are assembled in the upper mass to protect them from vibrations, although there are embodiments in which the motor is assembled in the lower mass, for example.
The ground compactor 100, 600 further includes: a first battery compartment 130 and a second battery compartment 140 for receiving respective first and second batteries 150; and a power circuit configured to supply electric power in a voltage range from the first or second battery to the at least one motor 210.
Thus, since the power circuit is configured to draw power from either of the batteries during operation, an operator may load a charged battery into one or both battery bays. If the battery is inserted into both battery compartments, the machine operation time is prolonged. For shorter duration work tasks, or if only one charged battery is available, a single battery may be used in one of the battery compartments, leaving the other battery compartment empty or occupied by a battery that is depleted of power. Since the battery capacity is divided into two in this way, each battery is manageable in terms of weight and form factor and thus can be conveniently carried to a working position by an operator.
According to an embodiment, the energy storage capacity of each cell is between 8Ah-12 Ah, and preferably about 9.4Ah. The rated voltage of the battery is preferably on the order of 36V, although other voltages are also conceivable. Batteries of this type may weigh on the order of 1kg to 3kg and are typically about 1.9kg. This type of battery is easy to handle manually, i.e. can be carried by an operator from a charging station to a ground compactor at a work site without difficulty. On the other hand, a twice as heavy battery would be more cumbersome to handle.
According to another embodiment, each battery may be configured to have a weight between 2500g and 5500g, and preferably 3000g or 5100g.
In the case of a battery capacity of 9.4Ah, the working time is of the order of 22 minutes, which means that a floor compactor with two fully charged batteries can be operated without interruption for about 44 minutes. This time span is sufficient to complete many tasks on the job site. Advantageously, however, one of the batteries may be removed and placed in the charging station while the ground compactor is in operation, thus allowing for a considerable operating time if the battery is cycled between the charging station and the ground compactor. In practice, three batteries may be used, one of which is always in the charging station, while the other two are inserted into the battery compartment. Due to the dual battery compartment system disclosed herein, battery switching may be performed while the floor compactor is in use.
According to various aspects, the motor and its associated power circuitry are arranged for continuous operation during removal and/or insertion of one of the first and second batteries, provided that the other is received in its corresponding battery compartment and has a minimum charge level. This feature may be referred to as a hot plug feature, wherein an operator may replace a battery without first stopping the machine. The possibility of hot plug of a charged battery with an empty battery may be particularly advantageous when compacting viscous materials (which may jam if the compactor is stopped for too long) or compacting more sensitive materials (which may mark if the compactor is left in one place for too long).
The battery is optionally separately connected to the motor drive circuit. This means that each battery compartment has its own separate connector which is wired to the drive circuit. The drive circuit is then in a position to select from which battery to draw power. In some cases, it may be preferable to draw power from only one of the batteries, such that only one battery is depleted. This is an advantage because the depleted battery can then be transported to a charging station and the ground compaction operation can continue with power from another battery. Thus, according to some aspects, a floor compactor includes a power circuit configured to select an active battery compartment from a first battery compartment and a second battery compartment, and to draw power from a battery inserted into the active battery compartment during use, provided the battery is inserted into the active battery compartment and has a sufficient charge level. When the active bay battery is depleted or removed from the battery bay, the power circuit is configured to switch the active bay to another battery bay. If a battery of insufficient charge is inserted into any of the pods, the power circuit is configured to deactivate the ground compactor.
The control panel may be arranged to indicate to the operator which battery compartment is the active battery compartment and which battery compartment is the inactive battery compartment. This allows the operator to remove the battery from the inactive battery compartment in a convenient manner.
According to a further aspect, the motor drive circuit may include an input port for receiving a signal determining which battery compartment is the active battery compartment. In this way, the operator may ignore the selection of the active battery compartment to manually select which battery should be used to power the floor compactor. For example, the signal may be generated from a control panel of the ground compactor.
Alternatively, the ground compactor may be further arranged to indicate when the active battery compartment has changed such that the operator receives a notification that one of the batteries has been depleted. The notification may be a visual signal (such as a flashing light) and/or an audible signal (such as a beeping sound, etc.).
According to a further aspect, the power circuit or control unit on the ground compactor may be arranged to switch the active battery compartment in case of a risk of overheating of the battery. In this way, the motor drive circuit can cycle back and forth between the batteries so that no battery becomes overheated. Batteries not used to drive the ground compactor will still receive a flow of cooling air discussed in more detail below in connection with fig. 4.
In summary, the floor compactor 100, 600 optionally comprises a control unit 160 arranged to select a movable battery compartment from the first battery compartment 130 and the second battery compartment 140 for driving the motor 210, wherein the selection of the movable battery compartment is based on any one of the following: there is a battery in one or both battery compartments, a state of charge of the inserted battery, a temperature of the inserted battery, and/or a manual selection of the active battery compartment.
The ground compactor optionally includes a third energy source separate from the two battery compartments. The third energy source may be configured to power control circuitry and a user interface of the ground compactor. This feature allows interaction with the operator even if no battery is inserted into the battery compartment. The third energy source is optionally arranged as a rechargeable battery and is recharged by a battery inserted into one of the battery compartments.
As mentioned above, stability is important in compactors. To provide an even distribution of weight, referring to fig. 2, the motor 210 may be configured to have a center of mass m lying within the first plane P1, and the respective geometric centers of the battery compartments 130, 140 may be configured to be separated from each other by the first plane P1. In other words, the motor 210 may be assembled between two battery compartments. This mass distribution also makes it easier to isolate the energy storage system from vibrations, for example by mounting the battery compartment on a carrier plate 220, which can then be assembled to the rest of the structure via vibration isolating elements such as rubber elements or other forms of dampers.
For example, referring also to fig. 5 and 7, the first plane P1 may be aligned with the motor shaft a of the motor such that two battery compartments 130, 140 are disposed on both sides of the motor shaft a. In other words, the motor shaft a of the motor 210 may be configured to be parallel to the first plane P1. Also, forward direction F of ground compactor 100 is configured to be orthogonal to first plane P1. This means that the battery is arranged on the longitudinal axis of the compactor, which is an advantage, since when arranged in this way the battery may be better protected from mechanical shocks etc. For example, a protective frame or other structure may be arranged to enclose both battery compartments, providing increased mechanical integrity in terms of design. According to some aspects, the first plane P1 may be perpendicular to the forward direction F. According to some aspects, the first plane P1 may extend parallel to the motor shaft a, but need not be aligned with the motor shaft a.
According to some aspects, as shown in fig. 5, motor shaft a has an extension that extends substantially parallel to the main extension of motor plate 540, to which motor 210 is mounted, according to some aspects.
Fig. 7 shows a preferred geometric arrangement 700 of the battery compartments 130, 140 and the motor 210. The motor 210 has a motor shaft (indicated as a) arranged to drive the ground compactor 100, for example via an external element. The second plane P2 perpendicular to the extending direction of the motor shaft a intersects the first and second battery compartments 130 and 140 and the motor 210. This means that the two battery compartments and the motor are aligned in the longitudinal extension direction of the compactor, i.e. mounted one after the other in the forward direction F. The battery compartments and the motor are preferably staggered such that the motor 210 is located between the first battery compartment and the second battery compartment, as shown in fig. 7.
Fig. 3 shows details 300 of plate compactor 100. Specifically, a battery housing 310 is shown in which the first battery compartment 130 and the second battery compartment 140 are integrally formed. The battery housing 310 is preferably assembled in the upper mass 110 of the plate compactor 100 via at least one vibration isolation element 350. The battery housing provides protection for both batteries and in particular prevents dust and moisture from entering into the electrical connection of the first and second batteries.
As shown in fig. 3, the battery housing 310 may further include a first battery compartment 320 and a second battery compartment 330 arranged to cover the first battery compartment 130 and the second battery compartment 140, respectively. Optionally, the cover may include a gasket to provide a watertight seal around the cover. The cover may be provided with a lock to prevent theft of the battery inserted into the battery compartment. The lock may be a mechanical lock or an electronic lock. The hatches 320, 330 are not necessary and the battery 150 may be disposed in the battery compartments 130, 140 without a cover or any other type of covering.
The battery housing 310 optionally includes a control panel (not shown in fig. 3) arranged to be accessible by an operator for controlling at least a portion of the power circuitry. The control panel may advantageously be arranged in a position between the first battery compartment cover 320 and the second battery compartment cover 330, which position protects the control panel from mechanical shocks or the like during operation. Providing a control panel on a housing such as that shown in fig. 3 is advantageous because the motor and battery are nearby, which reduces the need for wiring.
If the cover includes electronic locks, the control panel may be configured to control these locks, for example, by requesting the operator to enter a code to allow the battery to be removed from its compartment.
The control panel may also be arranged to indicate which battery compartment is currently being used to provide power to the motor so that the operator may remove the inactive battery from its compartment.
The control panel may also be arranged to indicate a respective state of charge of a battery inserted into the battery compartment. In this way, the operator can determine which battery needs to be charged and remove the battery for transportation to the charging station.
Referring also to fig. 4, fig. 3 also shows a fan 340 disposed on the motor shaft of the motor 210. The fan 340 is arranged to provide a cooling air flow 410 into the first battery compartment 130 and the second battery compartment 140. The cooling air flow 410 initially extends from the air inlet 420 in an extension direction 440 of the motor shaft, followed by a branching flow 430 from the motor shaft radially outward toward the first battery compartment 130 and the second battery compartment 140.
As the cooling air 410 is directed toward the first battery compartment 130 and the second battery compartment 140 via the motor 210, the cooling air 410 may be slightly preheated while passing through the motor 210. This is advantageous when operating at relatively low temperatures, as the battery capacity generally increases with temperature. This is also advantageous because if two batteries 150 are installed in the battery compartments 130, 140, but only one battery is used to power the motor 210, the other battery is kept at a suitable operating temperature by means of the cooling air 410 and is ready for use.
According to some aspects, the cooling air 410 is also directed towards the control panel and associated control unit 160 via separate directing means (not shown). The cooling flange may be attached to the control unit 160.
FIG. 5 illustrates an exploded view 500 of exemplary compactor 100. The plate compactor comprises a motor 210 arranged to drive an eccentric weight mechanism 510 comprised in the lower mass 120 via a drive belt 520. According to some aspects, the drive belt 520 is a polymeric V-belt that reduces frictional losses and thus increases battery run time. It is also conceivable to position the motor 210 so that it can directly drive the eccentric weight mechanism 510 without the need for a belt.
The ground compactor 100 includes: a bottom plate 530 arranged to contact the ground; an engine plate 540 assembled on the base plate 530 through a first group of vibration isolation elements 545; and a battery plate 550 assembled on the engine plate 540 by the second set of vibration isolation elements 350, wherein the motor is mounted to the engine plate 540 and wherein the battery plate is arranged for supporting the first battery compartment 130 and the second battery compartment 140. Notably, the plate 540 is referred to herein as an "engine plate" even though an electric machine is mounted thereon without an internal combustion engine. In this way, particularly effective vibration isolation is achieved, since vibrations from the ground have to pass through the two sets of vibration isolation elements 545, 350 before reaching the battery compartment. The first set of vibration isolation elements protects the motor from vibrations and indirectly protects the battery from vibrations. However, another set of vibration isolation elements provides further vibration isolation and thus increases the vibration protection of the battery. Having two sets of vibration isolation elements in this way also reduces oscillations between the battery compartment and the motor, which is an advantage.
According to some aspects, air is directed from the engine plate 540 to the battery plate 550 via one or more flexible air directing means (such as rubber channels) so that movement between the engine plate 540 and the battery plate 550 due to the second set of vibration isolation elements 350 may be handled.
According to some aspects, the battery compartment 130, 140 includes an electrical connector adapted to engage and contact a corresponding electrical connector included in the battery 150 when the battery 150 is inserted into the corresponding battery compartment 130, 140.
According to some aspects, the battery compartments 130, 140 are separate from each other. According to some aspects, the battery compartments 130, 140 need not be completely separate from each other, but rather each battery compartment 130, 140 is formed to receive a respective battery 155.
