Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning method for, for example, plowing and cleaning driving surfaces such as roads, highways and/or airport runways covered with snow, snowmelt, water, dust, mud, etc. Regarding equipment.

Equipment for cleaning driving surfaces such as roads, highways and/or airport runways that are covered with snow, snowmelt, water, dust, dirt, etc. must be installed transversely to the direction of travel or inclined at the work area. It comprises a framework containing two rotating drums around which a movable transport conveyor belt for the cleaned material is guided.

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 equipment must be able to operate at high speeds since the runway cannot be used for aircraft take-off or landing during this cleaning operation.

Moreover, runways are not only cleared of snow and/or snowmelt to ensure the safety of flight operations, but also water,
Dust, mud, etc. must also be completely removed. The same conditions are necessary for other driving surfaces such as roads and highways.

One device known for removing snow and/or snow melting mud present on driving surfaces, especially flight runways, is:
It has a brush roller that is rotated in a direction opposite to the running direction. This cleaning device can be used to clean snow and/or snowmelt mud. However, this device has the disadvantage that the cleaned material is rolled up by the brush roller and is transferred again so that the transverse velocity component reaches the surface traveled by the inclined position of the brush roller with respect to the direction of travel. There is.

This means that the width is equal to the length of the brush roller on the one hand,
and, on the other hand, for cleaning parts of the runway that depend on the inclined position of the rollers relative to their running direction, the cleaned material has to be engaged many times by the brush rollers and the removal or shifting device Despite the use of a second cleaning device or a second cleaning device using the same cleaning device, the device is thrown into the surroundings and is sent into the area transverse to the surface on which this device works, in front of the spiral. cleaning operation is carried out, and a distance approximately equal to the working width of the cleaning device is laterally removed. Therefore, this device has very low efficiency as far as cleaning the running surface is concerned.

Another disadvantage of this device is that in order to obtain a working width suitable for these conditions, very long brush rollers must be provided. Therefore, a very expensive structure is required. As a result, this device with brush rollers is mounted at its front end on a rotating frame on the bearings or support members of a supporting vehicle, such as a semi-trailer, and at its rear end on the undercarriage necessary to support this device. It has a support arm supported by.

Brush rollers are also known that require a towing vehicle and therefore have chassis at both the front and rear ends.

In each case, the constructional requirements require a very expensive chassis on which the brush rollers are mounted and which takes up the loads that occur on this device, for example due to rotational movements.

This has to be solved by correspondingly heavy support devices or bearings and expensive undercarriages, and so that unbalances of the cleaned material occur during rotation, which limit the reduction of the cleaning speed and therefore the working speed. This is especially necessary since snow and/or sludge areas can cause freezing on the brush rollers.

In other cleaning devices, the support frame has at least two rotating drums around which a conveyor belt for the cleaned material is guided in a lateral movement towards or inclined to the working position. There is. In this cleaning device, these drums assume a vertical position such that the conveyor belt lies in a plane perpendicular or at right angles to the running surface.

The known cleaning device also fails to satisfy the object of the invention, since it is not possible for the conveyor belt to bring both the front and rear areas into contact with the running surface at the same time, so that the forces acting in two directions cannot , transmitted to the support frame by a conveyor belt. Moreover, the cleaned material is sent to one area in the first direction and to the other area in the opposite direction.

As a result, in this known cleaning device, the conveyor belt must be kept at a distance from the surface over which it is run. This construction has the disadvantage that it does not allow complete cleaning of the surface traveled on, since the cleaning device is used to clean small amounts of material, e.g. small amounts of snow, or to remove chips and mud from the surface. In this case, there is no particular disadvantage.

In many cases, however, for airport runways, thorough cleaning of the running surface is required.

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

Furthermore, it is an object of the present invention to provide a more complete cleaning of driving surfaces in athletic operations than previously possible such as roads, highways and/or airports covered with snow, snowmelt, water, dust, mud, etc. An object of the present invention is to provide an improved device for cleaning runways.

Another object of the present invention is to provide a more complete, faster and more economical cleaning operation than previously possible for cleaning snow, melting mud, water, etc.
An object of the present invention is to provide an improved device for cleaning driving surfaces such as roads, highways, and airport runways that are covered with dust, mud, etc.

The above objects and others, which will become more apparent from the following description, are achieved by the present invention for cleaning driving surfaces such as roads, highways and airport runways that are covered with snow, snowmelt, water, dust, mud, etc. The apparatus is achieved and comprises a framework around which two rotating drums are mounted and around which a conveyor belt for cleaning material is guided which is movable laterally in the direction of the working place or inclined thereto.

According to the invention, the conveyor belt is movable in a position inclined at an acute angle with respect to the direction perpendicular to the running surface. One of the two tension surfaces of the conveyor belt is maintained in contact with the running surface, while the other, 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 belt tension surfaces of the conveyor belt, which is located towards the front with respect to the running direction of the device, contacts the running surface at an acute angle between 1° and 30°. do. Preferably, this acute angle is 8". In another embodiment of the invention, one of the belt tension surfaces facing rearward with respect to the direction of travel of the device is connected to the running surface, preferably 1° and 30". It is configured to make contact at an acute angle with °.

Since the belt tension side of the conveyor belt abuts the running surface, the material to be cleaned on the running surface is engaged. If not engaged, this tension surface stirs and flings the material, transporting it to the edge of the work surface of the apparatus according to the speed at which the conveyor belt is driven. It is then engaged during an additional cleaning operation and moved laterally again a distance approximately equal to the working width of the cleaning device.

Suitably, a plurality of guide rollers for the conveyor belt are mounted on the framework 2 in addition to at least two rotating 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 towards the front 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 one of the belt tension surfaces of the conveyor belt towards the rear with respect to the running direction of the device. Slide runners are arranged on the framework as opposing retainers 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 rotating 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 consisting of an elastic material reinforced with 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 externally to the conveyor belt. A plurality of height-adjustable brushes each acting on at least one spring are provided on the rod and/or cable.

A sleeve carrying a compression spring and a brush is guided along each rod and/or rope.

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 feature comprising a plurality of ribs and/or grooves, and the outer surface of the guide roller also has a longitudinally extending feature on the conveyor belt. and a further 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 plurality of ribs with a trapezoidal cross section on its inner surface, and a plurality of belt drums and guide rollers of the conveyor belt have a plurality of grooves with a trapezoidal cross section. In these constructions, the required contact of the conveyor belt on the running surface is ensured, 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 move the conveyor belt downwards relative to the belt drum after ablation of the conveyor belt by an amount corresponding to approximately equal spacing of the two elements. be. However, the conveyor belt
l which has only a fraction of its initial height without its action being hindered! It is often used.

Preferably, the guide drum is formed by a pair of rubber tires. Between these tires a strip runs lengthwise from the inside of the conveyor belt.

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

In another embodiment of the invention, the framework has ventilation and/or suction devices. A downwardly opening air duct is carried by the framework. The mounting frame can be movably connected to the support frame of the support vehicle by means of a support pipe acting as an air duct, and the blowing and/or suction device is mounted on the support frame. Air ducts opening into the running surface are provided on the framework between the conveyor belts extending over the length of said framework, connectable by support pipes to a blower device. 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 two support pipes 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 plate member, and the control cover disposed at the mouth of the branch pipe is acted upon against the action of the adjustment spring due to the air flow. .

The cleaning operation may be assisted by a blower device to improve the cleaning performance of the conveyor belt and/or to allow the dumping of the cleaned material to the ground to improve performance. The cleaned material is drawn in by a suction device and fed into a collection container located on the support vehicle.

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

The framework is rotatably mounted and a positioning device for rotating the framework against the direction of travel of the device is disposed between the support frame and the framework.

Retaining elements for the plurality of belt drums and guide rollers are
The height and rotational position of the conveyor belt can be adjusted relative to the framework, thereby allowing the height and rotational position of the conveyor belt to be adjusted relative to the operating plane.

The support rails or members of the conveyor belt within the framework are rotatable about an axis extending along the length of the support wheels. The support rails of the conveyor belt are held within the framework housing by elastic strips or intermediate bearing members.

A spray device is placed in front or behind the conveyor belt. A drive motor, a hydraulic pump driving at least one belt drum of the conveyor belt, a blower and/or suction device, and a container with a feed pump are arranged on the support vehicle.

A snow plow is attached to the front end of the support vehicle.

A third embodiment of the invention will now be presented, which has a simpler construction than the previously described embodiments, being formed without a blower or suction blower. This device is placed at the front end of the support vehicle 1 instead of a snow shovel.

As is clear from FIGS. 11 and 12, this cleaning device 70 is attached to the front end of the support vehicle 1 by means of a coupling device 71. As shown in FIGS. This device also includes a conveyor belt 74 and is supported by wheels 75. A conveyor belt 74 is mounted around two belt drums 76 and 77 and is driven by a motor. The height of the conveyor belt 74 is adjusted by means of a cylinder 72 located mostly vertically. The tilting position of this device with respect to the direction of travel is adjusted by two transverse cylinders 73.

In FIG. 13, a conveyor belt 74 is wrapped around a drive drum 76 and a guide drum 77, as can be seen from FIG. In addition, two pairs of tension rollers 81 are attached to the front belt tension side 74.

As a result, the front belt tensioning surface 74a of the conveyor heald 74 can be tensioned and/or changed in position relative to the framework of the apparatus by adjusting the rotational position of the tensioning roller 81.

As is clear from FIG. 14, the drive drum 76 is formed by two foam tires 85 and 87, whose hubs 86 and 87 are rigidly connected to each other. The guide drum 77 is constructed in a similar manner.

The conveyor belt 74 has a plurality of ribs 90 on its inside, which are centrally located with respect to the height of the conveyor belt 74, projecting between both tires 85 and 87. Thus, conveyor belt 74 is maintained at the required height regardless of the loads acting on it. Conveyor belt 74 has a plurality of ribs 92 on the outside oriented transversely to its length.

As is clear from FIG. 15, the conveyor belt 74 is
It is supported in the central region with respect to its height by a guide roller 84 which projects into the groove 91 of the rib 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 drum 76 and the guide drum 77. conveyor belt 7

This tendency is being resisted. As a result, a satisfactory cleaning result is obtained.

As mentioned above, the conveyor belt 74 is maintained in an inclined position relative to the running surface 3. As a result, the front heald tension surface 74a comes into contact with the ground while traveling on the running surface 3, while the rear belt tension portion 74b is lifted off the ground. Material in contact with the front belt tensioning surface 74b of the conveyor belt 74, which contacts the running surface 3 during operation of the conveyor belt 74, is carried away.

The installation of this cleaning device is shown in FIGS. 16 and 17. Obviously, the support frame 4a supports the support vibe 1
It is in rigid contact with the support vehicle 1 by 00.

A retaining plate 101 with a housing 102 attached thereto supports the support pipe 10 in which four elastic strips 103 are arranged.
It is attached to 0. Bolts 105 are held by these elastic strips, on which rails 107 are mounted on both sides. The rail 1.07 forms the support frame of the cleaning device. This flexible attachment of the support frame can perform rotational movements relative to its holding member, whereby the attachment to the surface to be cleaned can adjust its inclination.

In FIG. 18, strip 2 of conveyor belt 23
It is shown that 4 can be equipped with a metal cutting member 26 for cutting and/or dividing the cleaned material. From FIGS. 19 and 20, the conveyor belt 23
It is clear that the strip 24 has one or more brushes 27 so that the running surface 3 can be further cleaned.

Another embodiment of the conveyor heald 74 is shown in FIG. It has on its outside a plurality of upper and lower longitudinal strips 110, on which are mounted the rads and/or cables 112. A sleeve 113 with a laterally projecting bolt 114 is attached to the rod and/or cable 112. 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 passageway 119 is provided, which serves as a receptacle for the contact bin.

Since the brush 115 is pressed onto the running surface by a spring 116, the brush also performs a cleaning action. When the movement of the sleeve 113 is limited by the stop 117, the brush 115 located on the front belt tension surface a of the conveyor belt 74 becomes active. In order to easily maintain continuous operation as soon as the lower edge of the conveyor belt 74 is worn out by abrasion and is no longer functional, this belt is used in an overturned manner due to the high degree of symmetry of its construction.
