Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applicable to driving surfaces such as roads, highways and/or airport runways covered with snow, snowmelt mud, water, dust, mud, etc. , for example, relates to a cleaning device for raking and cleaning.

[Conventional technology]

An apparatus for cleaning driving surfaces such as roads, highways and/or airport runways covered with snow, snowmelt, water, dust, mud, etc., comprising a framework fitted with two rotatable drums, the apparatus comprising: A conveyor belt for the cleaned material, which is movable transversely to the direction of travel, is guided around the two rotating drums.

In particular, airfield runways need to be thoroughly cleaned of snow and/or snowmelt that can impede air traffic. In addition to meeting high cleaning standards, the runway cleaning system must be able to operate at extremely high speeds since the runway is closed to aircraft landings and departures during this cleaning operation.

Moreover, the runway must not only be cleared of snow and/or snowmelt, but also completely cleared of water, dust, mud, etc., in order to guarantee the safety of flight operations. Similar conditions exist for other driving surfaces such as roads and highways.

One device found on driving surfaces, particularly flight runways, for removing snow and/or snowmelt is the
It has a brush roller that is rotated in a direction opposite to the running direction. With this cleaning device, the running surface can be cleaned of snow and/or snowmelt and made clean.

[Problem to be solved by the invention]

However, in this device, the cleaned material swirls around due to the rotation of the brush roller, and due to the inclined position of the brush roller with respect to the running direction, the cleaned material reaches the running surface with a lateral velocity component. It has the disadvantage of having to be cleaned again.

This means that for cleaning sections of the runway, the width of which on the one hand depends on the length of the brush roller,
And on the other hand, due to the inclined position of the rollers relative to their direction of travel, the cleaned material has to be engaged many times by the brush rollers and, despite the use of removal or shifting devices, does not disturb the surroundings. It is then thrown into the air in a spiral motion into an area transverse to the surface on which the device is working. A second cleaning operation is then carried out using a second cleaning device or the same cleaning device, and said cleaned material is again transversely moved in this second cleaning operation a distance approximately equal to the working width of the cleaning device. be excluded. therefore,
This device has very low efficiency as far as cleaning the running surface is concerned.

Another disadvantage of this device is that it must be equipped with very long brush rollers in order to obtain a working width suitable for these conditions. Therefore, a very expensive structure is required. As a result, this device with said brush rollers is mounted on a rotating frame at its front end on a bearing or support member of a transport vehicle, such as a semi-trailer, and at its rear end it is necessary to support the device. It has a support arm supported by a substructure. Because brush rollers require a towing vehicle, brush rollers are also known that have lower structures at both the front and rear ends.

In each case, the structural requirement is that the brush rollers are mounted in a very expensive longitudinal substructure in which the loads caused, for example, by rotational movements are received.

This is especially necessary since snow and/or sludge portions of the material being cleaned may freeze on the brush rollers. This is because imbalances occur during rotation, which must be resolved by correspondingly heavy support devices or bearings and expensive undercarriages, which are dependent on the cleaning speed, This limits the reduction in working speed.

In other cleaning devices, the support frame has at least two
It has two rotating drums around which a conveyor belt for the cleaned material is guided in a transverse movement in the direction of travel or obliquely in the direction of the working position. In this cleaning device, these drums assume a vertical position such that the conveyor belt is located in a plane perpendicular or at right angles to the running surface, so that this known cleaning device also ensures that the conveyor belt is under tension in front and behind. Since both surfaces cannot be brought into contact with the running surface, the cleaning efficiency is poor and the object of the present invention cannot be satisfied.

As such, forces acting in two different directions are transmitted to the support frame by the conveyor belt. Moreover, the cleaned material is conveyed in a first direction by one tension surface of the conveyor belt and in the opposite direction by another tension surface, so that
The result of this is that in this known cleaning device the conveyor belt must be removed from the running surface. This structure has the disadvantage that the running surface cannot be completely cleaned. This is not particularly a disadvantage if the cleaning device is used to clean small amounts of material, for example small amounts of snow, or to remove dust or mud from running surfaces. In many cases, however, especially for airport runways, a more thorough cleaning than that of the running surface is required.

The object of the invention is to prevent the above-mentioned disadvantages by
It is an object of the present invention to provide an improved device for cleaning driving surfaces such as roads, highways and/or airport runways covered with snowmelt, water, dust, mud, etc.

It is further an object of the present invention to provide a more complete cleaning of driving surfaces covered with snow, snowmelt, water, dust, mud, etc. in a single operation than was previously possible. or to provide improved equipment for cleaning airport runways.

Another object of the present invention is to more completely than before:
Providing high-speed and economical cleaning work,
An object of the present invention is to provide an improved device for cleaning driving surfaces, such as roads, highways, and airport runways, covered with snow, snowmelt, water, dust, mud, and the like.

[Means and actions for solving the problem]

These purposes, and others that will become clearer from the description that follows, are intended to be used in equipment for cleaning driving surfaces such as roads, highways and airport runways that are covered with snow, snowmelt, water, dust, mud, etc. Achieved by the present invention, the device comprises a framework, in which two rotating drums are mounted,
A conveyor belt for the cleaning material is guided around the rotating drum and is movable transversely to the direction of travel. According to the invention, the conveyor belt is movable in a position inclined at an acute angle between 1° and 30° with respect to the perpendicular to the running surface, and one of the two belt tension surfaces of the conveyor belt is in contact with the running surface. , while another oppositely moving tension surface of the conveyor belt can be lifted from the running surface.
As a result, a very satisfactory cleaning of the running surface is obtained without all the disadvantages mentioned above.

According to a first embodiment of the invention, one of the tension surfaces of the conveyor belt, facing forward with respect to the running direction of the device, is in contact with the running surface, the acute angle of which is between 1° and 30°. It is between. This acute angle is preferably 8°. In another embodiment of the invention, one of the belt tension surfaces facing rearward with respect to the running direction of the device is configured to be in contact with the running surface, the acute angle thereof being between 1° and 30°; Particularly suitable is 8°.

Since the belt tensioning surface of the conveyor belt abuts the running surface, the material to be cleaned on the running surface is engaged. If this is not done, this tension surface agitates and throws the material to be cleaned, transporting it to the edge of the working surface of the device in accordance with the speed at which the conveyor belt is driven. The material to be cleaned is then engaged in an additional cleaning operation and is again moved laterally through a distance approximately equal to the working width of the cleaning device.

Advantageously, a plurality of guide rollers for the conveyor belt can be mounted in the framework in addition to at least two belt drums for the conveyor belt. Furthermore, a plurality of tensioning rollers, the position of which can be adjusted relative to the framework, are associated with one of the belt tensioning surfaces facing forward with respect to the running direction of the device.

These tensioning rollers are mounted on guide members whose rotational position is adjustable.

The rotational position of the guide member is adjustable with a turnbuckle.

The plurality of support rollers are also associated with a belt tensioning surface of the conveyor belt facing rearward with respect to the running direction of the device. A sliding surface is arranged on the framework as a holding plate for the conveyor belt.

Guide rollers, tension rollers, support rollers and sliding rails are provided so that the conveyor belt is maintained in position and under the tension required by the conditions. At least one of the two belt drums of the conveyor belt can be driven by a hydraulic motor and the drive for the conveyor belt is reversible.

According to another aspect of the invention, the conveyor belt is constructed of a rigid elastic material comprising an elastic material reinforced by additional materials. Elastic materials include rubber or plastic materials, and additional materials include steel fibers, steel sheets, glass fibers, carbon fibers or slag fibers.

An additional working unit including a cutting member and a brush is attached to the lower, longitudinal edge of the conveyor belt. In this way a plurality of rods and/or cables are held outside the conveyor belt. A plurality of adjustable height brushes each acting on at least one compression spring are guided along the rod and/or cable. Cleaning operations carried out by the conveyor belt are easily facilitated or carried out by this cutting and/or brushing operation.

According to a further embodiment, the inner side of the conveyor belt has a longitudinally extending profile comprising a plurality of ribs and/or grooves, and the outer side of the guide roller also has a longitudinally extending profile on the conveyor belt. It has another circular cross-sectional portion including a plurality of spaced apart grooves or ribs opposite the shaped portion extending in the direction.

Thus, the conveyor belt has a trapezoidal cross-section shaped portion on its inner surface, and the plurality of belt drums and the guide rollers of the conveyor belt form grooves of trapezoidal cross-section. These structures ensure the required contact of the conveyor belt on the running surface, since it is maintained at the correct height by the belt drum and guide rollers. As long as these profiled or grooved elements are equally spaced from each other, it is possible to maintain the conveyor belt downwards with respect to the belt drum even after abrasion of the conveyor belt by an amount corresponding to approximately equal spacing of the two elements. be. The conveyor belt can therefore be used as long as it has only a fraction of its original height without its action being weakened.

Preferably, the guide drum is formed by a pair of rubber tires. Between these tires
The shaped portion is oriented lengthwise from inside the conveyor belt.

According to another preferred embodiment, the conveyor belt is formed with a plurality of vertically extending ribs on its outside or inside, and the inside of the conveyor belt is provided with a longitudinally extending groove, in which at least one The guide roller protrudes. These aspects also ensure good guidance of the conveyor belt.

In another embodiment of the invention, the framework is equipped with a blower and/or suction device. A downwardly opening air duct is held by the framework. The mounting frame is movably connectable with the carrier frame by means of a support pipe acting as an air duct, the support pipe acting as an air duct blower and/or suction device is mounted on the support frame. . Air ducts opening into the running surface can be connected by support pipes to a blower device and are provided on the framework between the conveyor belts extending over the length of said framework. A conduit is opened inside the conveyor belt which is connected to the suction device by means of a support pipe. Each of the two branch pipes of the support pipe is connected to each end of a downwardly opening air duct. A control cover is disposed at the mouth of the support pipe and each branch pipe.

Therefore, the control cover disposed at the mouth of the support pipe is a rotatable disk, and the control cover disposed at the mouth of the branch pipe is moved by the air flow against the action of the adjustment spring. can be acted upon.

The cleaning operation may be performed by using a blower to improve the cleaning performance of the conveyor belt and/or by allowing the cleaned material to be brushed onto the ground. The cleaned material is drawn in by a suction device (blower) and fed into a collection container located on the transport vehicle.

Preferably, the framework has a plurality of wheels. At least one positioning cylinder is mounted on the support frame, by which the framework can be lifted.

The framework is rotatably mounted, and a positioning motor for rotating the framework against the direction of travel of the device is disposed between the support pipe and the framework.
The holding members for the plurality of belt drums and guide rollers are adjustable in height and angular position with respect to the framework, thereby making the height and angular position of the conveyor belt adjustable with respect to the operating plane.

A support rail or member of the conveyor belt within the framework is rotatable about an axis extending along the length of the vehicle. The support rails of the conveyor belt are held within the framework enclosure by elastic strips or intermediate bearing members.

A water sprinkler is placed in front or behind the conveyor belt. A drive motor, ie a hydraulic pump driving at least one belt drum of the conveyor belt, a blower and/or a suction device, and a container with a feed pump are arranged on the transport vehicle. A snow blower is attached to the front end of the truck.

To use the device according to the invention, the cleaned material is fed to either the right or left edge of the working surface, said support device being rotatably mounted facing the carrier and at least A positioning cylinder and a motor are arranged between the transport vehicle and the support device, thereby adjusting the lateral position of the support device relative to the direction of travel. The drive of the conveyor belt is thus reversible.

In order to use the blower in a suitable manner, the air duct has two branch pipes at each end of this air duct which open downward. A control valve is disposed in the branch pipe near the mouth and in the duct near the branch pipe mouth so that the blower air is guided downwardly from left to right or from right to left. into the duct.

"Working unit" shall include the conveyor belt, any brushes used to aid in cleaning the running surface, and any cutter elements, blowers, water sprinklers, etc.

By "shape" we mean ribs and/or grooves on the inside of the conveyor belt, and by "cutout" we mean grooves formed in guide rollers, rotating drums, etc.

The above and other objects, features and advantages of the invention will be apparent with reference to the accompanying drawings, which are illustrated in a highly illustrative manner:

From FIG. 4 it can be seen that the rotatable disk 33 is in this embodiment a cylindrical body, in which a curved airflow deflector 33a is mounted. This rotatable disk 33 is connected by a pin 38 fixed to a lever 39. Rotating the lever 39 causes rotation of the rotatable disk 33. The airflow supplied by the blower 6 is guided from one of the branch pipes 30, 31 into the other by rotation of the rotatable disc 33.

As can be seen in FIG. 5, the framework 13 is equipped at both ends with belt drums 40 along which the conveyor belt 23 is guided or rotated. Additionally, a plurality of guide rollers 45 for the conveyor belt 23 are mounted within the framework 13 along its length.

Conveyor belt 23 has a plurality of vertical ribs 24 extending generally vertically on its outer side.

An air duct enclosure 16 forming an air duct 17 opening into the running surface 3 is supported by a framework 13 . The support pipe 11 is connected to the air duct enclosure 1

A sliding surface 63 supported by an arm 64 is arranged in the upper part. This sliding surface 63 acts to prevent the front belt tension surface 23a of the conveyor belt 23 from lifting off the guide roller 45.

A hydraulic motor 48 is arranged inside the at least one belt drum 40 to drive the conveyor belt 23. A shaft 49 of this hydraulic motor 48 is paired with and fixed to a central shaft 50 of the belt drum 40. The air duct 17 is connected to the conveyor belt 23
An elastic strip 65, open to the air and therefore adjustable in height, closes off the rear of the cleaning device and is mounted at the rear of the air duct.

In the operating position of the conveyor belt 23, the sixth
As is clear from the figures and FIG. 7, the front conveyor belt has a front belt tension portion 23a.
is inclined at an angle of approximately 8° to the normal n of the running surface 3 and is held in contact with the running surface 3.
Due to the inclined position of the conveyor belt 23, the rear belt tension surface 23b of the conveyor belt is located at a distance from the running surface. By driving the conveyor belt 23, the material positioned by the front belt tension surface 23a of the conveyor belt 23 on the running surface, such as snow and/or snowmelt mud, water, dust, mud, etc., is It is grabbed or engaged and moved away transversely to the direction of movement of the conveyor belt 23.

The material to be cleaned is fed through the support pipe 11 and the branch pipes 30, 31 through which air flows laterally.
This is facilitated by air directed downwardly into the air duct 17 through one of the air ducts 17.

Therefore, depending on the position of the rotatable disc 33, the air stream is fed to the left or right end of the air duct 17 and flows through it towards the other end in the feed direction of the conveyor belt, thereby The cleaned material is blown laterally to a lower position on the running surface 3. The angle at which the front belt tension surface 23a is oriented is between 1° and 30° with respect to the perpendicular n to the running surface 3.

A cross-sectional and plan view of a variant embodiment of the cleaning device described above is shown in FIGS. 8 to 10. Front belt tension surface 23 of conveyor belt 23

b moves in the direction of arrow D.

This material is fed into a collection container arranged on the transport vehicle 1 through a support member or support pipe 11 which acts as a suction duct.

A third embodiment of the invention is shown next, which is formed without a blower or suction blower.
Having a simpler construction than the previously described embodiments, this cleaning device is arranged at the front end of the vehicle 1 instead of the snow shovel.

As is clear from FIGS. 11 and 12,
This cleaning device 70 is attached to the front end of the transport vehicle 1 by means of a coupling device 71. The device is likewise formed with a conveyor belt 74;
and is supported by wheels 75. Conveyor belt 74 is mounted around two belt drums, a drive belt drum 76 and a guide belt drum 77, and is driven by a motor. The height of conveyor belt 74 is adjusted by cylinder 72, which is located almost vertically. The tilting position of this device with respect to the direction of travel is adjusted by two transverse cylinders 73.

In FIG. 13 this device is shown schematically. As is clear from the figure, the conveyor belt 7
4 is wrapped around the drive belt drum 76 and the guide belt drum 77. Further, two pairs of tension rollers 81 are arranged on the front belt tensioning surface 74a, and two guide rollers 84 are arranged on the rear belt tensioning surface 74b. A tensioning roller 81 is mounted on a guide member 82, which is rotatable by a turnbuckle 83. As a result, the front belt tension surface 74 of the conveyor belt 74
a can be tensioned by adjusting the rotational position of the tensioning roller 81 and/or change its position relative to the framework of the device of the invention.

As is clear from FIG. 14, the drive belt drum 76 is formed by two rubber tires 85 and 87, whose hubs 86 and 88 are rigidly connected to each other. The guide belt drum 77 is constructed in a similar manner. The conveyor belt 74 has a shaped portion 90 located centrally inside thereof;
Regarding the height of the profile 90 of the conveyor belt 74, it has a profile 90 that projects between the two foam tires 85 and 87. Conveyor belt 74 is thus maintained at the required height regardless of the loads acting on the conveyor belt. Conveyor belt 74 has a number of ribs 92 on its exterior oriented transversely to its length.

As can be seen in FIG. 15, the conveyor belt 74 is supported in its central part by a guide roller 84 at its height, which projects into a groove 91 in the shaped section 90.

By means of tensioning rollers 81 arranged in the upper and lower parts of the conveyor belt 74, the conveyor belt 74 can be moved slightly forward in the running direction A in the central part between the drive belt drum 76 and the guide belt drum 77. .

Due to the inclined position of the conveyor belt 74, the centrally located front belt tension surface 74a contacts the running surface 3 with great pressure and/or the front belt tension surface 74a is centered between the drive belt drum 76 and the guide belt drum 77. It is opposed to being raised and separated from the area. As a result, a satisfactory cleaning result is obtained.

As mentioned above, the conveyor belt 74
maintained in a tilted position. the result,
Its front belt tension surface 74a comes into contact with the ground while traveling on the running surface 3, while the rear belt tension surface 74b is lifted off the ground. Materials found in contact with the front belt tensioning surface 74a of the conveyor belt 74, which contacts the running surface 3 during operation of the conveyor belt 74, are carried away.

The installation of this cleaning device is shown in FIGS. 16 and 17. Obviously, the support frame 4a is in rigid contact with the carrier 1 via the support pipe 100.
A retaining plate 101 formed by a shroud 102 is attached to the support pipe 100, and inside the shroud 102 four elastic strips 103 are arranged. Bolts 105 connect these elastic strips 10
3, and support rails 107 are mounted on both sides on bolts 105. The support rail 107 forms the support frame of the cleaning device.

This flexible attachment of the support frame allows the cleaning device to perform a rotational movement relative to its holding member, thereby adjusting the inclination of the attachment to the surface to be cleaned.

In FIG. 18 it is shown that the ribs 24 of the conveyor belt 23 can be provided with metal cutting members 26 for cutting and/or dividing the cleaned material. It is clear from FIGS. 19 and 20 that the ribs 24 of the conveyor belt 23 have one or more brushes 27 so that the running surface 3 can be further cleaned.

Another embodiment of the conveyor belt 74 is shown in FIG. It has a plurality of upper and lower longitudinal ribs 110 on its outside, to which rods and/or cables 112 are attached. The rod and or cable 1
Attached to the rod and/or cable 112 is a sleeve 113 having a bolt 114 projecting laterally from 12 . A downwardly directed brush 115 is supported by bolts 114. The sleeve 113 is under the action of a compression spring 116. Movement of the sleeve is limited by fasteners, such as bolts. A through hole 119 is provided, which serves as a receptacle for the contact pin.

Since the brush 115 is pressed onto the running surface by the compression spring 116, the brush also performs the cleaning task. The movement of the sleeve 113 is caused by the stopper 1
17 when the conveyor belt 74
The brush 115 located on the front belt tensioning surface 74a of is activated. As soon as the lower edge of the conveyor belt 74 becomes worn out by abrasion and no longer functions, the belt, due to the high degree of symmetry of its construction, can tip over to easily maintain continuous operation. used.

〔Effect of the invention〕
