Definitions

  • the invention relates to a soil compaction device, in particular a vibration plate or vibrating plate.
  • Such a soil compaction device has a vibration exciter driven by a motor, which generates a substantially vertically directed vibration which acts on a compaction plate (soil contact plate).
  • a compaction plate soil contact plate
  • it is suitable for moving the compaction plate forwards or backwards over the soil to be compacted and for making the plate steerable.
  • Such a soil compaction device is available as a vibration plate, for example DE 198 40 453 A1 known. It has an extendable chassis so that the machine can cover shorter distances on a construction site without the need for a transport vehicle.
  • the Indian DE 198 40 453 A1 The chassis mechanism described is structurally complex, heavy and expensive.
  • a simpler transport device in which a set of wheels is attached directly to the compaction plate (soil contact plate). By tilting the vibration plate around the wheel set, the ground contact plate can be lifted off the ground and the entire vibration plate can be transported or rolled away with the help of the wheel set.
  • a device for compacting road surfaces is described, with a mobile frame on which an internal combustion engine and a generator connected to it are arranged.
  • a compressor plate equipped with a vibration exciter is mounted on the wheeled frame.
  • the invention is therefore based on the object of providing an improved soil compaction device that can be transported comfortably and without any special effort.
  • a soil compaction device is specified, with a lower mass having a compaction plate, an upper mass coupled to the lower mass via a vibration decoupling device, a vibration exciter acting on the compaction plate, a chassis with one or more rolling bodies for transporting the device, and with an electric drive for driving at least one the rolling body, with an electrical energy storage device being provided, for supplying the electric drive with electrical energy.
  • the lower mass therefore has the compaction plate which serves as a ground contact plate and on which the soil compaction device rests on the ground.
  • the compaction plate is caused to vibrate by the vibration exciter and causes the soil underneath to be compacted.
  • the vibration exciter or parts of the vibration exciter can also be attributed to the undermass.
  • the drive can be arranged on the upper mass, which is vibrationally decoupled from the lower mass. However, in other embodiments, the drive can also be arranged directly on the lower mass.
  • the vibration decoupling device between the lower mass and the upper mass can in particular be a spring-damper device, e.g. with rubber buffers, in order to effectively isolate the vibrations arising and generated on the lower mass from the upper mass.
  • the one or more rolling bodies are used to roll over the ground in order to carry the entire soil compaction device and to be able to transport it rolling over the ground.
  • the rolling bodies can in particular be designed as wheels, with several wheels, in particular a pair of wheels, forming a wheel set.
  • the electric drive is used to support the transport movement, which can, for example, have an electric motor and can drive at least one of the rolling bodies in rotation.
  • the support of the electric drive makes it easy for an operator to move the soil compaction device on the ground using the rolling bodies. The operator then only has to guide the soil compaction device in a suitable manner and, if necessary, balance it, while the actual transport movement is effected by the electric drive and the rolling bodies driven by it.
  • the electrical energy storage can in particular be a battery or an accumulator.
  • the energy storage can be permanently installed in the soil compaction device. However, it is also possible to provide the electrical energy storage in a replaceable manner.
  • the chassis can be attached in a stationary manner to the lower mass, the chassis being at a distance from a contact area
  • Compaction plate is arranged, which is dimensioned such that the soil compaction device can be tilted over the rolling bodies, such that the compaction plate does not touch the ground in a transport position, but the rolling bodies touch the ground and carry the weight of the device.
  • the rolling bodies In a working or shaking position, however, when the compaction plate rests flat on the ground, the rolling bodies are arranged at a certain distance from the ground. The rolling bodies, so to speak, float above the ground or the contact area.
  • the stationary attachment of the chassis to the lower mass means that the relative position between a chassis axis or axis of rotation of the rolling bodies to the lower mass carrying the chassis, in particular to the compression plate, is unchangeable.
  • the rolling bodies can rotate relative to the compaction plate. However, their relative position to the compaction plate cannot be changed.
  • the stationary chassis axis with respect to the compaction plate means that the rolling bodies are already in their driving position (transport position) during working operation (shaking operation).
  • the stationary chassis axis with respect to the compaction plate means that the rolling bodies are already in their driving position (transport position) during working operation (shaking operation).
  • the stationary chassis axis with respect to the compaction plate means that the rolling bodies are already in their driving position (transport position) during working operation (shaking operation).
  • the stationary chassis axis with respect to the compaction plate means that the rolling bodies are already in their driving position (transport position) during working operation (shaking operation).
  • a carrying device can be provided with which the chassis is movably attached to the upper mass, with the chassis using the carrying device between a working position in which the soil compaction device is suitable for compacting a soil and a transport position for transporting the Soil compaction device is movable.
  • the carrying device is therefore used to move, in particular to pivot, the chassis relative to the upper mass. In the shaking position or working position, the rolling elements of the chassis are raised from the ground.
  • the chassis can be held on the upper mass with the rolling bodies.
  • the chassis is pivoted downwards so that the rolling bodies are supported on the ground and the entire soil compaction device can be transported.
  • the chassis can have at least two rolling bodies, of which at least one rolling body can be driven by the electric drive.
  • Different variants are possible. It is therefore possible for only one of the rolling bodies to be driven in rotation, while the other rolling body is mounted to rotate freely.
  • both rolling bodies can be driven. It is possible for both rolling bodies to be driven by a common drive. It is also possible for each of the rolling bodies to have its own individual drive.
  • the two rolling bodies can be connected to one another by a torque coupling, such that both rolling bodies are driven together by the electric drive.
  • the torque coupling can be produced, for example, by a connecting shaft, a gear, etc. in order to couple the rotational movement of the two rolling bodies to one another.
  • the common electric drive can accordingly be attached at a suitable location in order to transmit the torque to both rolling bodies.
  • a controller can be provided for activating the electric drive, with the controller being able to bring about a standby state in which the electric drive for the chassis can be activated while the vibration exciter cannot be activated.
  • the standby state means that transport operation is possible in which the electric drive can be activated. In the standby state, however, no working operation (shaking operation) is possible.
  • the standby mode represents a preliminary stage to the actual transport operation, in which the vibration exciter may no longer be activated.
  • the standby state can be activated by a switching device, whereby the switching device can have various components or functional principles.
  • the switching device can have a tilt detector to detect whether the soil compaction device is tilted about the chassis axis. If the soil compaction device is tilted - as described above - about the chassis axis (axis of rotation of the wheelset or axis of rotation of the rolling bodies), the rolling bodies touch the ground so that the soil compaction device can be transported. This tilted or inclined state can be detected by the tilt detector, whereby the standby state can be activated.
  • the switching device can have a drawbar detector for detecting a position of a guide drawbar in an upright locking state.
  • Many soil compaction devices have a guide bar with which an operator can manually guide and move the soil compaction device.
  • a corresponding locking device for example to snap it into the upper mass.
  • this locking state of the guide drawbar can be detected, which in turn enables the standby state to be activated.
  • a transport operating device can be provided for activating the electric drive in at least one direction of rotation of the associated rolling body and thus the transport direction of the soil compaction device.
  • an operator can switch the electric drive on and off in order to cause the corresponding rolling body (or several rolling bodies) to rotate and to carry out the transport.
  • a rocker switch or rocker button or a control lever for forward and reverse travel can be suitable as a transport control device, similar to an electric pallet truck. It can also be provided that the electric drive can only be activated if the standby state was previously activated.
  • the speed of the electric drive can be constant, i.e. unchangeable.
  • the operation of the electric drive is limited to on-off or forward and reverse travel as well as standstill.
  • a guide device can be provided for manually guiding the soil compaction device by an operator, wherein the guide device can be attached to the upper mass.
  • the guiding device can be, for example, the guiding drawbar described above.
  • a vibration decoupling device can be provided between the guide device and the upper mass. This can, for example, have rubber buffers.
  • the electrical energy storage can be arranged on the upper mass, on the lower mass or on the guide device.
  • the arrangement on the upper mass and - even more - on the guide device has the advantage that these locations can be vibration-decoupled from the lower mass, so that the energy storage is only exposed to small vibrations.
  • the vibration exciter can be driven by an electric working drive, the electric working drive being supplied with electrical energy from the electrical energy storage.
  • the soil compaction device has a large electric drive that serves as a working drive and drives the vibration exciter.
  • the electric working drive as well as the electric drive for the chassis are fed together by the electrical energy storage.
  • the vibration exciter can be driven by an internal combustion engine, wherein a starter battery can be provided for a starter of the internal combustion engine and the starter battery forms the electrical energy storage for the electric drive for the vehicle.
  • a starter battery can be provided for a starter of the internal combustion engine and the starter battery forms the electrical energy storage for the electric drive for the vehicle.
  • the actual work drive for the vibration exciter is provided by the internal combustion engine.
  • the starter battery which is designed as a battery with a smaller capacity, is used to supply the starter and the electric drive for the chassis.
  • the energy storage for the electric drive can be rechargeable by the internal combustion engine. Accordingly, the energy storage does not have to have a large capacity. It can be charged during operation by the internal combustion engine, which accordingly has or drives a generator.
  • a charging device can be provided for monitoring a charge state of the energy storage device, whereby at least one of the following functions can be guaranteed: if the remaining charge falls below a predetermined upper residual charge limit, switching off (or preventing it from being switched on) the working drive for the vibration exciter; and when falling below a predetermined lower limit Residual charge limit Switching off (or preventing switching on) of the electric drive for the chassis.
  • the charging device thus makes it possible to monitor the charge status of the energy storage device. If the energy storage also serves to power an electric working drive for the vibration exciter, this working drive can be switched off when the specified upper residual charge limit is not reached, while at this point in time operation of the travel drive or electric drive for the chassis is still possible. The chassis can then continue to be driven while the vibration exciter is switched off.
  • FIGS. 1 to 4 show essentially the same soil compaction device according to the invention as a vibration plate, each from different angles and in different operating states. Since the figures refer to the same object, they are described together.
  • a drive belonging to an upper mass 4 and hidden under a cover 5 is positioned, coupled via a spring-damper device 3 (e.g. a rubber buffer) serving as a vibration decoupling device.
  • a spring-damper device 3 e.g. a rubber buffer
  • the drive usually a gasoline or diesel engine, drives a vibration exciter 6, which is coupled to the compaction plate 2 in such a way that the vibrations generated by the vibration exciter 6 are transmitted directly to the compaction plate 2 and thus into the soil to be compacted.
  • the drive can also be an electric drive and have an electric motor.
  • the drive can be arranged on both the upper mass 4 and the lower mass 1. If the electric motor is located on the upper mass 4, a suitable power transmission is provided between the electric motor and the vibration exciter 6, for example a belt drive or a hydraulic drive known per se. However, if the electric motor is arranged on the lower mass 1, it can drive the vibration exciter 6 directly.
  • An energy storage device required for the electric motor can be arranged on the upper mass 4, for example under the cover 5. As a result, the energy storage is also decoupled from the vibrations acting on the lower mass 1.
  • a chassis 7 is arranged on the lower mass 1 and has a chassis axle 8 which is stationary with respect to the soil compaction device and around which one or more rolling bodies 9 are rotatably arranged.
  • the figures show two rolling bodies 9 designed as wheels, which together form a wheel set.
  • the chassis 7 is attached to the lower mass 1, in particular to the compression plate 2. This reduces the center of gravity distance of the entire device from the chassis axle 8, which in turn improves the driving behavior of the device in transport operations. In addition, the tendency of heavy compaction plates to tip over in the direction of travel around the chassis axle 8 during transport is reduced.
  • the two rolling bodies 9 can be driven in rotation by an electric motor 15 in order to facilitate transport of the entire vibration plate in the transport position of the vibration plate using the rolling bodies 9, which are then in contact with the ground.
  • the electric motor 15 rotates the rolling bodies 9, causing them to roll over the ground and thereby carry the remaining soil compaction device in a rolling manner.
  • the operator can operate a control not shown in the figures, for example a rocker switch or a control lever, in order to switch the electric motor 15 on and off or to specify a direction of rotation of the electric motor 15.
  • a control not shown in the figures, for example a rocker switch or a control lever, in order to switch the electric motor 15 on and off or to specify a direction of rotation of the electric motor 15.
  • the electric motor 15 can, for example - as in Fig. 2 shown - be arranged between the two rolling bodies 9. It is also possible to design the electric motor 15 as a hub motor, which is then arranged in at least one of the rolling bodies 9 or in both rolling bodies 9.
  • the chassis axle 8 can consist of an actual component, but it can also be a fictitious axis of rotation, which is formed by supports 8a, 8b attached to the compression plate 2, which each carry the rolling bodies 9 ( Figs. 2 and 4 ).
  • the axis position of the chassis axle 8 is selected for a given diameter of the rolling bodies 9 such that in a shaking position ( Fig. 3 ) the compaction plate 2 has surface contact with the ground and the rolling bodies 9 do not touch the ground (distance b), but in a transport position ( Fig. 4 ) the compaction plate 2 does not touch the ground (distance a), but the rolling bodies 9 touch the ground and support the weight of the device.
  • a change between the two positions is possible by tilting the entire device about an axis which essentially corresponds to the chassis axis 8. By simply tilting the compaction plate 2 away in the direction of a drawbar 10 serving as a guide device, for example, the change from the vibrating to the Transport position possible.
  • a control lever is provided on the drawbar 10, with which the vibration exciter 6 can be controlled in a manner known per se.
  • the axis position of the chassis axle 8 and the size of the rolling bodies 9 such that the distance b ( Fig. 3 ) between a ground contact surface of the compaction plate 2 and the lowest point of the rolling bodies 9 in the shaking position and a distance a ( Fig. 4 ) by which the rolling bodies 9 protrude in front of the then lowest point of the compaction plate 2 in the transport position. If the distance a is sufficiently large, the soil compaction device can be moved without any problems even on uneven ground, while at the same time the distance b must be selected so that it is ensured that the rolling bodies 9 do not touch the ground during shaking operation.
  • the chassis axle 8 is arranged above the compression plate 2, whereby a favorable relationship between the line of action of the operator's tractive force on the drawbar 10, the center of gravity of the overall device and the position of the chassis axle 8 is possible, so that very good driving comfort is achieved without a tendency to tip over in the direction of travel.
  • the soil compaction device is then balanced in equilibrium so that its center of gravity is essentially vertically above the chassis axis 8.
  • the rolling bodies 9 Since arranging the chassis 7 on the lower mass 1, in particular on the compression plate 2, also causes the rolling bodies 9 to be subjected to high acceleration, it is recommended to provide the rolling bodies 9 with a targeted unbalance 11 so that they vibrate develop the desire to rotate around the chassis axis 8 on its own. This counteracts selective wear of the rolling body bearings.
  • the use of rolling bearings for the rolling bodies 9 is therefore particularly suitable.
  • the embodiment shown here has a tread surface 12 for supporting the moment required to change the positions laterally on the upper mass 4, so that the operator can, for example, load the tread surface 12 with his foot and tilt it backwards or forwards the drawbar 10 can reach the driving position or transport position.
  • This type of change from the shaking to the transport position and vice versa involves a significantly lower risk of injury compared to soil compaction devices with swiveling or extendable chassis and can be carried out very quickly because no modification of the chassis is required.
  • the tread surface 12 can also serve as a protective cover for the electric motor 15 behind it.
  • the drawbar 10 is in the Fig. 1 to 4 pivoted upwards from the usual operating position into a locking position. In this position, the drawbar can be locked by a locking device, not shown, in order to achieve a compact unit with the remaining vibration plate for transport.
  • the second requirement for activating the standby state is that the vibration plate is tilted, as in Fig. 4 shown.
  • the tilting of the vibration plate by pivoting around the rolling bodies 9 can be detected, for example, by an inclination sensor.
  • control elements not shown in the figures are activated as a transport control device, via which the electric drive can be switched on or off in order to drive the rolling bodies 9 in rotation and to move the vibration plate above the ground.
  • Fig. 5 shows a schematic bottom view of a variant of a vibration plate serving as a soil compaction device.
  • two rolling bodies 9a, 9b designed as wheels are provided, which have a common axis of rotation (chassis axis 8).
  • an electric drive 15 is provided as a hub motor, through which the rolling body 9a can be driven in rotation.
  • the other rolling body 9b (in Fig. 5 the lower one is simply mounted so that it can rotate freely and is not driven.
  • steering assistance can be achieved by changing the speed of rotation, both in terms of the speed of rotation and the direction of rotation.
  • both rolling bodies 9a and 9b are each assigned their own electric drive 15.
  • the two electric drives 15 can be individually be controlled in order to achieve steerability of the vibration plate. If the two electric drives 15 are operated in opposite directions, the respective rolling bodies 9a, 9b also rotate in opposite directions, so that the vibration plate can be rotated on the spot.
  • Fig. 6 shows a variant in which the electric drive 15 is also used as a hub motor in the rolling body 9a (in Fig. 6 the upper rolling body) is arranged. However, the other rolling body 9b is coupled via a shaft 16 to the electric drive 15 or the rolling body 9a.
  • the electric drive 15 is not assigned directly to one of the rolling bodies 9a, 9b, but is arranged approximately centrally between the two rolling bodies 9a, 9b. Accordingly, the electric drive 15 can have two shaft outputs (shafts 16).
  • the electric drive 15 can also have only one shaft output, which is then guided to only one of the rolling bodies 9a, 9b.
  • Fig. 8 shows another variant in which the electric drive 15 - similar to Fig. 5 - is only assigned to the rolling body 9a, while the rolling body 9b rotates freely.
  • the electric drive 15 is not designed as a hub motor, but as a separate motor that drives the associated rolling body 9a via a gear shaft mechanism 17.
  • the electric drive can have a friction wheel that can be pressed onto one of the rolling bodies (transport wheel).
