Description

Wheel washing system

The present invention relates to a tire washing system according to the preamble of claim 1.

There are numerous situations, such as construction sites, quarries and landfills, where it is necessary to wash the tires of a truck before leaving the yard and driving on the public roads to keep the roads clean and safe. For this purpose, tire washing systems of the type mentioned are used.

GB 2 347 846 describes a generic tire washing system, which has an open top

Dirty water collection container comprises, over which a grate is arranged, which is to be run over by the vehicle to be washed. On both sides of the grate extending in the longitudinal direction of a pipeline which is provided with nozzles for generating an inwardly directed water jet. Below the grate run two more tubes with upwardly directed nozzles to produce an upwardly directed jet of water.

Since the transit length of the grate is usually much shorter than the rolling distance of a wheel, ie the circumference of the wheel, can not uniform, complete -? -

Cleaning the wheel done. Compared to conventional stationary or complex mobile systems with correspondingly long processing areas with separate basins, this disadvantage has been taken into account in favor of the compact, mobile design

The object of the present invention was to propose such a tire washing system, which overcomes this disadvantage.

This object is solved by the features of the characterizing part of claim 1. Further embodiments of the invention are defined in the further claims 2 to 8.

The tire washing plant has a dirty water collection container, above which there is a processing line, which is to be traversed by a vehicle to be washed and are arranged on the supplied via a central supply system gun. To the

Processing section then at least one extension wing is arranged, which comprises an extension supply system and feeds further, formed on the extension wing beam generator. Through this extension wing, the entire processing line is extended so that a comprehensive cleaning of the entire tire can be done without the compactness of the plant suffers. For example, two extension wings are formed, which are arranged opposite each other to the processing section. Advantageously, a symmetrical entire processing path is created using equal expansion wings. It can in particular by using the same resp. identical components for the two extension leaves a cost-effective and compact design can be created.

For example, the expansion wing (s) can be detachably fastened to the dirty water collecting tank and the expansion supply system (s) can be detachably connected to the central supply system / whereby the detachable connection of the expansion wing on the

Dirty water collection container in a known manner, e.g. done by screwing. This creates a particularly favorable and space-saving arrangement of the components for storage and transport. For example, all components of such a tire washing plant can be stored and transported in conventional containers. With typical dimensions, two such tire washing systems can advantageously be accommodated completely in a standard 20-foot container.

For example, the processing section and the extension wing (s) together form a drive-over surface whose length in the direction of travel is at least 300 cm. In order to The length of the entire processing area is approximately in the range of the circumference of a conventional truck tire.

For example, the waste water collection container is box-shaped or cuboid open and open or the

Extension wings each extend away from the upper edges of opposite side walls of the dirty water collection container. Thus, the dirty water runs without further funds in the central area of the system and can drain from there down into the waste water collection tank. From there, the water can be pumped back into it by a pump

Be fed to central supply system, wherein the dirt accumulates in the bottom area and deposits.

For example, the extension wing (s) each extend upward from the dirty water collection container and / or have a bottom with a slope sloping down to the dirty water collection container, so that the ground

Expansion wing impinging waste water flows under the influence of gravity to the waste water collection tank.

For example, the extension supply system is connected to the central supply system. Thus, the extension supply system uses the pump of the central supply system and is, for example, directly or via additional lines connected to the existing piping system.

For example, the extension supply system is directly connected to the waste water collection tank and has its own drive. As drive usually a pump is used. Thus, the extension supply system is independent of the central supply system operable.

A tire washing system according to the invention is more compact than known tire washing systems with the same overall length of the processing area. It can be easily and without major structural adjustments to the environment set up and set up what just for example

Road construction projects with a dynamically changing processing locations is an advantage.

An embodiment of the present invention will be explained in more detail with reference to figures. Show it:

2 shows an inventive tire washing system, schematically, in plan view. 3 shows a section on the line AA according to FIG. 1;

4 shows a section on the line B-B according to FIG. 1; and

5 shows a section on the line C-C according to FIG. 1.

Fig. 1 shows schematically and in perspective view of an inventive tire washing system, which initially consists of a top open waste water collection tank 1, which serves to receive dirty water that accumulates in the cleaning of the tire. On one of the end faces 11 of the dirty water collection container 1, a known dirt conveyor 4 for the promotion of sludge from the dirty water collection container 1 is arranged.

Above the dirty water collecting container 1 there is a processing line BE, which is defined by a carrying device described in FIG. 2, to be traversed by the vehicle to be washed in traversing direction P, P 'and in traversing direction P, P' over the entire length of Opening the waste water collection tank 1 extends. Along the processing line BE, beam generators 3 for generating water jets for cleaning the tires are arranged.

FIG. 2 shows a plan view of a tire washing system according to the invention. On the opening of the waste water collection container 1, the support device is mounted, which is run over by the vehicles during cleaning in the direction of travel P, P 'and is formed in the embodiment shown as a grate 5. With the upper edge of the dirty water collection container 1, two expansion wings 2 are connected, which are provided for extension or extension of the processing section BE in the direction of travel P, P ', respectively attach to one of the two longitudinal sides 12 of the dirty water collection and outwardly away from the processing section BE extend.

The grate 5 comprises slats 50, which extend transversely to the direction of travel P, P '. The mutually spaced slats 50 form between them slots 51, through which the resulting wastewater in the tire cleaning enters the waste water collection tank 1,

At the dirty water collection container 1 is also a

Provided central supply system, which is the supply of the beam generator, ie the supply of water to the beam generators used. In the illustrated embodiment the central supply system consists of two central tubes 10 which extend along the edge of the waste water collection container 1 along its end faces 11, while it is in the embodiment shown to the central tubes provided on a line, at intervals arranged known spray nozzles 3.

The extension wings 2 each comprise a main body 23, which is run over by the vehicles during cleaning in the direction of travel P, P ', and an extension supply system, which is in flow communication with the central supply system and the supply of water to further, provided on the extension wings 2 beam generators 3 is used, which are for example also to spray nozzles 3 is.

In the exemplary embodiment shown, the extension supply system is a U-shaped extension tube 20 which extends at the edge of the main body 23 and two mutually parallel

Leg portions 22 of rectangular cross-section and a base portion 21 includes.

It is conceivable that the arrangement consisting of the central tubes 10 and the two extension tubes 21 is integrally formed. - S -

In a special embodiment, in which the extension wings 2 can be fastened detachably to the dirty water collecting container 1 and the extension tubes 20 can be connected to the central tubes 10 in a detachable manner, the extension tube 20 is connected to the two central tubes 10 in a known manner with tube connecting means, such as e.g. Sleeves. This embodiment is advantageous because the tire washing system can be disassembled into individual parts, which can be stored in a space-saving manner for transport.

The central tubes 10 and the two extension tubes 20 constitute a cohesive piping system via a port (not shown). is supplied with a pump (not shown) under pressure, which is pressed by the spray nozzles 3 and formed into a jet of water.

The dirty wash water flows back into the dirty water collection tank 1 and is used again after cleaning. For example, the amount of water lost in each vehicle wash is automatically replaced again.

In principle, it is also conceivable to provide the tire washing system with only one extension wing 2, it being clear to the person skilled in the art that in each case the two central tubes 10 must be connected to one another. It is also conceivable to provide as a support device instead of the grate 5 rollers, which extend parallel to each other and at a distance from each other between the end faces 11 of the dirty water collection container.

It should be noted that spray nozzles 3 can also be arranged elsewhere than in the exemplary embodiment. For example, It is conceivable to place under the grate 5 bottom spray nozzles, which produce an upwardly directed, passing through the slots 51 beam.

The grate 5 defines, with the basic bodies 23 of the two extension wings 2, an area to be traveled by the vehicle to be washed in the direction of travel P or P ', which deviates slightly from the plane, since the grate is arranged horizontally, but the extension leaves are inclined slightly upwards. at an angle of about 1 ° to 5 ° to the horizontal of

Dirty water collection container 1 away outward. That is, the expansion wings 2 fall to Dirty water collection container 1 down from, so that the incident on the base body 23 dirty water flows back under the influence of gravity in the waste water collection tank 1. This can also be done, for example, by a direction of travel P resp. P 'in a longitudinal section wedge-shaped, for dirty water collection container 1 point tapered execution of the extension wing 2 can be achieved. Advantageously, the soil area around the waste water collection container 1 can easily be simply leveled or left practically unprocessed in favorable soil conditions. The wedge-shaped extension wings 2 can then easily come to rest on this floor area and be supported against it, wherein the dirty water can easily zurückfHessen in the waste water collection tank 1.

The processing path BE and the extension wings together form a drive-over surface whose span in the direction of travel P, P 'corresponds or is greater than at least approximately the circumference of a truck tire. Thus, the processing area extends in the direction of travel P 'P' with a total length which is at least in the range of a truck tire circumference.

The base portion 21 is run over during the cleaning process of the vehicles to be washed and has, for example, a rounded cross section to protect the vehicle tires. Of course, the formation of a small ramp is conceivable here. 4 shows a section on the line BB according to FIG. 2.

The two V-shaped downwardly converging plates 14 form a sludge channel, from which the sludge is removed from the dirt conveyor 4 and discharged from the waste water collection tank 1.
