Designation: <^ Set of parts to form a device for
Cleaning vehicles to avoid
Road pollution j>

The invention relates to a set of parts for forming a device for cleaning vehicles to avoid
Road pollution.

It is well known that vehicles, especially trucks that come from a construction site, a rubbish dump or any other unpaved driving surface and drive onto paved roads, cause very severe contamination on these roads by hanging on the wheels, especially between the twin wheels of trucks, and at increasing driving speed Earth thrown off the road. This pollution of the road is not only unsightly and
annoying, but also creates a great danger for other road users because the road becomes uneven and slippery in wet weather. For this and other reasons, where such vehicles pass over to public roads, the road must be continuously cleared of dirt, for which purpose
a relatively large amount of personnel and machines

is required. However, the dirt often doesn’t leave it like that Eliminate far that there is no risk of slipping for the other road users when it rains.

The object of the invention is to create a device with which the roads are prevented from being polluted by such vehicles their emergence is avoided; whereby the expenditures for this In addition, costs should be even lower than the costs that have previously been incurred for subsequent cleaning of the streets had to. The invention should be able to be carried out as a permanently installed device, but in particular also as a "flying" device, that is, as a device that can be set up quickly and with little effort at a point of need. If the If the drive-up point of the vehicles is moved to the street, the device should be installed quickly at the new drive-up point can.

According to the invention, a device of the type described at the outset is distinguished Kind of solving the above-mentioned problem by means of passable segments of a ramp with perforated plates or gratings, by means of spray nozzles which are attached below the segments and which are essentially directed upwards Connections for a high pressure source and by a responsive under a weight load of the ramp control device to Switching the spray nozzles.

The invention thus provides a set of parts for forming a device before, which is arranged in the route of the vehicles as close as possible to the access point on the road and via the the vehicles have to drive. When driving onto the ramp of the device, the vehicle automatically switches the spray nozzles so that the vehicle and especially the driving

-werk of the vehicle from below with high pressure water jets hosed down and the dirt is rinsed off. When rolling off the device, the switch Spray nozzles automatically turn off again.

According to a preferred embodiment of the invention it is provided that the ramp is made up of a plurality of one behind the other in the direction of travel of the vehicle Segments whose spray nozzles are switched individually or in groups by the control device *

As a control device for switching the spray nozzles on and off Any conventional switching devices, such as light barriers or the like, can be used will. According to a preferred embodiment of the invention, however, it is provided that the control device operated from the weight of the approaching vehicle There is pressure control slide.

Here it is expediently provided that each segment has its own pressure control slide for its spray nozzles is provided. You can use the pressure control spool of the Arrange and train middle segments so that they, even if they are not directly from the wheels of the The vehicle is charged as long as it remains open as one in front of and one behind these middle segments lying segment is loaded by a standing vehicle wheel. This is how you submit that the The underside of the vehicle is sprayed between the axles of the vehicle. The individual wheels of the vehicle roll over the samp and load the individual segments one after the other, with the wheels in such a case

- 4 Ural runs of all are rarely hosed down.

According to a particularly preferred embodiment of the invention it is provided that the segments of the device are transportably and releasably attached to one another, so that you can use the device as a "flying" system in the sense explained above.

You can either have a solid substructure at the place of use the device or search for the substructure divided into segments and designed to be transportable.

In the substructure, collecting channels for the drainage water are expediently provided. The Sanmel channels can have a connecting piece have for connection to a sewer line.

Water that has been fed in under high pressure must be used for hosing down. Therefore it is useful to use as High pressure water source a high pressure water pump, which is arranged in the device and either from a Pipeline network or is fed from a nearby body of water.

Further objects, features and advantages of the invention emerge from the following description of an exemplary embodiment, reference being made to the accompanying drawings. In the drawings shows;

In the exemplary embodiment of the invention shown in the drawings, the device generally designated IO consists of a lamp which is arranged in the vehicle's path as shortly as possible before the transition to the road 12 and via which the vehicle 14 drives 01065 tm to get onto the road. In the exemplary embodiment shown, the device 10 consists of several segments 11 and 2 * ei ramp parts 13 arranged one behind the other in the direction of travel of the vehicle at both ends. If only a certain type of vehicle is to drive over the device 10, it may be sufficient to arrange a narrow lane of gratings for the cadres on both sides of the vehicle.

In each segment 11 a spray nozzle gallery 20 is arranged under the perforated plate or grating 12, these spray nozzle galleries 20 being connected via a collecting line 18 to a high-pressure water pump 16, which is fed via a line 17 from a barrel network or from a nearby body of water is * In the branch line between the collecting line 18 and the individual spray nozzle galleries 20 is shown schematically at 22! Arranged pressure slide, which is closed in the idle state and which opens when a vehicle is there * grating 12 of the segment 11 concerned * The spray nozzle galleries 20 have a number of spray nozzles 23, which - as can be seen in particular from Fig. 3 - such are arranged that their water jet the wheels and the bottom of the

Vehicle thoroughly splashed everywhere. The exact alignment of the individual nozzles naturally depends on the type of vehicle to be sprayed and you can if necessary, fasten the spray nozzles 23 with ball joints on the spray nozzle galleries 20 in order to achieve an alignment of the spray nozzles 23.

r The segments 11 of the device can AEU £ ei ** * »* n place substructure produced 26 (FIG. 1) established" ground "" ecn the device longer time au remain "oll ^ one place you can, but - according to the Representation at 26 * in wing. 3 - Also produce the substructure from transportable individual parts »in order to be able to set up the device 10 with its substructure in a short period of time at any location.

In the substructure collecting channels 28 are expediently formed laterally, which have a sufficiently steep gradient to to let the accumulating sludge and dirt run off. The resulting dirty water can be drained into a stream will. For this purpose, 28 connecting pieces 30 with Änsealußflanschen are at the lowest points of the collecting channels 32 provided. If necessary, it is also possible to connect the connecting pieces 30 to a public sewer network, as the spray water is usually sufficient to continuously carry the accumulating sludge through the sewer network wash away.

If a water source with sufficiently high pressure is available, the high pressure water pump 16 can be omitted and the collecting line 18 directly to this high pressure water source be connected.

The individual segments 11 are connected to one another by means of rapidly releasable devices (not shown) in order to to give the overall device 10 the necessary stability.

During operation, a vehicle drives onto the device 10, xaa shortly before it is driven onto the road. here freed from the dirt and soil clinging to the earth . will. As soon as the front wheels load the first segment 11, the high-pressure switch 22 of this segment opens and the loader and the underside of the vehicle are thoroughly hosed down. The wheels roll on to the next segment 11 and are here sprayed from a different side of their circumference. In this way, the feet roll once completely on the device 10 and are hosed off and cleaned from all sides. Finally, the rear wheels of the vehicle also reach the device 10 and are hosed down in the same way, the space between the twin tires also being thoroughly cleaned.

Since the pressure switches 22 are only open in the segments 11 loaded by the wheels, so da0 If water emerges from the nozzles 23, the underside of the vehicle 40 located between the axles would under certain circumstances not enough rejection. To avoid this, you can press the switch 22 in the middle segments 11 train in such a way that they remain open as long as the pressure switch 22 in the front and rear them lying segments 11 are opened by a standing vehicle wheel. This can be done with a suitable linkage or also preferably by a hydraulic

The invention is of course not tied to the details of the exemplary embodiment shown. Instead of the pressure switch 22, a light barrier could also be used, for example, to open and close the BruckttASsefzufuhr to the spray nozzles 23. While in the illustrated embodiment, the segments 11 are arranged high, the device 10 could also be designed so that it is sunk into the ground and the grating plates 12 are at ground level.
