Description

Tire Washing System with Second Wash Water Delivery System

technical field

The invention relates to a tire or crawler cleaning device.

Background technique

There are, for example, numerous situations in construction sites, quarries, mines and garbage areas where it is necessary to wash the tires of a vehicle before it leaves the point of use and travels over a large stretch of public road. It is important here to keep the roads clean and the traffic safe. Another application is the cleaning of vehicles before they drive across the runway area of an airport. A tire washing device of the type mentioned at the outset is used for this purpose.

Tire washing plants of this type are known and marketed by the applicant.

Known tire washing installations have a bridge grille structure through which vehicles to be washed can drive. Cleaning takes place in the area of this grid structure. Spray water from the nozzles onto the tires and lower chassis area during cleaning. Dirty water drips down through the grate structure where it can be collected by a dirty water container. Known tire washing systems have nozzles arranged in the region of the grid structure. These nozzles are supplied by a clean water-delivery system. The tire washing system includes a pump for supplying cleaning water. The pump is connected to the clean water-delivery system. Known tire washing systems have nozzles close to the chassis in order to generate a water jet which hits the vehicle to be cleaned in the region of the tires and undercarriage. Such a tire washing installation can carry a vehicle (if necessary a truck with a load).

Contents of the invention

The task of the present invention is to create an improved tire or track washing plant.

This object is achieved according to the invention by a tire or track cleaning system having the features of claim 1 . This is achieved by:

- a second group of nozzles comprising at least one nozzle is arranged in the region of said grid structure and is fed by a second washing water delivery system, and

- A second pump is coupled to said second wash water delivery system for delivering wash water.

In this way, two groups of nozzles can be operated simultaneously, which place different demands on the pump with regard to pressure and flow. Thus the first group of nozzles can for example comprise a large number of spatially distributed nozzles with small nozzle cross-sections and the second group can comprise nozzles with large nozzle cross-sections which apply a large amount of washing water to typically intense dirty parts. In this case the second pump can be specially designed for high flow rates. The inventors have realized that this surprisingly improves the overall efficiency of the plant. Overall better cleaning results are achieved with such a tire washing system.

Further embodiments according to the invention result from the features of claims 2-11.

In one embodiment, at least one nozzle from the second group of nozzles has a nozzle cross-section that is at least ten times, preferably at least one hundred times, the largest nozzle cross-section of the nozzles from the first group of nozzles.

With such a large nozzle, intensive cleaning of heavily soiled spots in the area of the undercarriage can be carried out. In this embodiment, for example, the nozzles in the second group of nozzles can have a nozzle cross-section of greater than 10 cm ² , while the nozzles in the first group of nozzles have a nozzle cross-section of up to a maximum of 10 mm ² . Since the nozzles of the second group are fed by a dedicated pump, a particularly high flow rate can be achieved through the nozzles. For example, the second group of nozzles can consist of pairs of such large nozzles, a wash water flow of 900 1/min being achievable for each nozzle.

In one embodiment, the jet direction from at least one nozzle of said second set of nozzles is oriented perpendicular to said grid structure.

In one specific embodiment, particularly heavily soiled areas on the underside of the vehicle are typically cleaned optimally. For example, according to this embodiment, intensive cleaning of mudguards can be achieved with this arrangement of nozzles.

In one embodiment, the grid structure includes at least one cleaning water pipe, the cleaning water pipe is arranged transversely to the central axis of the grid structure and has a nozzle for bearing.

In this embodiment, the tires or tracks of the vehicle to be cleaned can be hit by the beams from the grid structure from a short distance. The tires or tracks roll here directly through the cleaning water pipes with nozzles. A plurality of nozzles can be arranged in different positions along the transverse direction of the roadway.

In one embodiment, the at least one cleaning water pipe with nozzles which plays a supporting role is connected to the first cleaning water distribution system.

In one embodiment, at least one nozzle is integrated in a nozzle module, which is detachably connected to the supporting washing water line.

The nozzles can thus be exchanged together with the nozzle module and can also be cleaned separately by the tire washing device. The nozzle modules can be constructed quite simply in plate form. The perforations for the bolts can enable a detachable connection to the wash water distribution system, in particular directly to the wash water pipe in the grid structure. The nozzles may be designed as perforations passing through the nozzle module.

In one embodiment, the at least one cleaning water pipe with nozzles which plays a supporting role has a direction component parallel to the central axis of the grid structure.

This embodiment allows nozzles to be arranged with a spray direction perpendicular to the pipe direction of the cleaning water pipe while having a component transverse to the direction of travel of the vehicles to be cleaned. Thereby improving the cleaning efficiency.

In an embodiment with a plurality of washing water pipes with nozzles serving a load-bearing function, for at least a part of said washing water pipes with nozzles serving a load-bearing function, it applies that in the direction of the pipe and in the The angle between the directions of the central axis satisfies the condition:

60°≤α≤88°,

preferred

70°≤α≤80°.

With the pipe orientation in this angular range, on the one hand, a deliberate lateral component of the water jet that leads to more efficient cleaning is achieved, and on the other hand, the washing water pipe extending in this range ensures a good grate structure that can be driven through. of adhesion. The grate structure is completed by the nozzle-free profile elements arranged between the wash water pipes. Such a profile element is preferably oriented parallel to the wash water pipe. The rinsing water pipes and the profile elements arranged in an oblique direction increase the travel effect in the case of tire-tyred vehicles which can be driven over by tracked vehicles. Overall, the inclined arrangement also results in a high level of quiet operation and improved stability.

In one embodiment, the washing water pipes with nozzles that serve as bearings are arranged in an arrow-shaped arrangement on both sides of the central axis.

This embodiment reduces the risk of tires slipping laterally on the grid structure and additionally improves grip, quiet running and stability.

In a further embodiment, further nozzles are arranged at a distance from the grid structure.

Further nozzles can be arranged on the sides of the passage area, for example above the grid structure. The further nozzles can, for example, be coupled to the first or the second rinsing water distribution system. It is likewise conceivable for the other nozzles to be fed by other rinsing water distribution systems and to be connected to other pumps at the other rinsing water distribution systems.

A further embodiment has at least one nozzle module comprising at least one of the further nozzles, wherein the nozzle module is detachably connected to one of the rinsing water delivery systems.

Since the nozzle module is detachably connected to one of the rinsing water delivery systems, the nozzle module can be easily replaced. Depending on the degree of contamination and the type of vehicle to be cleaned, a nozzle module adapted to the situation can be used. Such nozzle modules can be configured, for example, as horizontally or vertically oriented nozzle beams. It is also particularly advantageous for cleaning dirty nozzles that cleaning does not have to take place directly at the tire washing system. A further advantage results from the fact that the nozzle modules, which are smaller than the washing water line or the grid structure, are easy to handle. This fact allows a particularly economical production method for the nozzle module.

All mentioned embodiments can be combined with one another as desired, as long as they do not contradict each other and as long as the combination is technically feasible.

Furthermore, the tire washing installation according to the invention can be combined with known elements of this type of tire washing installation. A dirty water collection container can thus be arranged below the grid structure. Dirty water can be purified in a purification plant and reused. A pump and distribution system for washing water can supply washing water pipes with nozzles and other nozzles in the grid structure with washing water. Walls arranged laterally to the tire washing device prevent splashing of dirty water and serve as holders for further nozzles. Further laterally arranged load-bearing elements can be part of the grid structure in the vicinity of the washing water pipe. Depending on the application, for example, water to which detergents or disinfectants have been added is conceivable as cleaning liquid, in addition to pure water. Designs of tire washing plants which simplify transport to another location of use are known and can also be applied to the tire washing plant according to the invention. The tire washing installation according to the invention can additionally have approach and departure ramps. An alternative installation with a flat floor is possible.

A steel frame extending along the tire washing installation can be used as longitudinal support structure. The longitudinal load-carrying structure may function to guide water and form part of a washing water distribution system. The longitudinal support structure can also be a reinforced rim of a dirty water collection container or a dirty water channel. In the case of permanently installed tire washing plants, longitudinal load-bearing structures constructed of concrete are also considered.

Even though the device according to the invention is called a tire washing device, its application is also suitable for cleaning tracked vehicles, such as construction machines or armored vehicles, due to the durable construction type.

Detailed ways

In FIG. 1 a tire or track washing plant according to the invention is shown. The area to be traversed by vehicles to be washed is shown in a perspective view with the grid structure 1 . The two pumps 21 and 22 and their connections 23 , 24 to the wash water inlets 25 , 26 of the first and second wash water distribution systems are schematically drawn. The drive-through grid structure 10 has the shape of two roadways.

Wash water pipes 30 with nozzles 11 are arranged between the obliquely arranged transverse bars of the grid structure. The washing water pipes with nozzles are identical in shape to the bars of the grille structure and likewise assume a load-bearing function. Furthermore, nozzles 11' are arranged at the edge of the grid structure. The nozzles 11, 11' are fed by a first wash water distribution system, the inlet 25 of which is coupled to a first pump 21. Most of the piping of the first and second wash water distribution systems is not visible in the illustration. These pipes run partly under the grid structure. Dirty water can drip down through the gap between the grille and the supporting wash water pipe 30 with nozzles, where it is caught by the dirty water container. A further nozzle 12 is arranged in the region of the grid structure. The nozzle 12 has a large nozzle cross-section and its jet direction is directed upwards perpendicular to the grid structure. The nozzles 12 are fed by a second rinsing water distribution system, the inlet 26 of which is coupled to a second pump 22 . The nozzles 12 are designed for high flow rates and are used for intensive cleaning of the chassis. For orientation, the central axis M of the grid structure and a Cartesian coordinate system with x-axis x (transverse direction), y-axis y (travel direction of the vehicle to be cleaned) and z-direction z (vertical line) are plotted.

In Fig. 2. a) a tire or track washing plant according to the invention is shown in top view. The tire washing system is here composed of two modules of the type shown in FIG. 1 , so that a double-length travel section results. The length of a single cleaning module may be, for example, 3.6 m. The traversing section of the tire washing equipment composed of two modules is 7.2m. These modules each have an inlet 25 for the first rinsing water distribution system and an inlet 26 for the second rinsing water distribution system. The pump of the tire washing system is not shown in the diagram. Each module may have a dedicated pump for supplying wash water. For reasons of clarity, only part of the nozzles 11 of the first group, the nozzles 12 of the second group and the rinsing water pipe 30 with the nozzles are provided with reference numerals. The cleaning water pipes 30 with nozzles that serve as bearings are arranged on both sides of the central axis of the grid structure 10 in an arrow shape.

The area framed in dotted lines and marked with the reference symbol B in which such a washing water line is located is also shown enlarged in FIG. 4 . By way of example, the pipe direction u is drawn as an arrow for one of the wash water pipes 30 . Figure 2.b) shows the same tire washing device in side view, and Figure 2.c) shows the tire washing device in front view, that is to say in the direction of observation in the direction of travel of the vehicle to be washed. The left and right walls that prevent dirty water from splashing sideways can be seen in the front view. Below the grill structure there is a dirty water container. Further nozzles 13 are arranged in the region of the side walls at a distance from the grid structure 10 .

In FIG. 3 the tire washing plant from FIG. 2 is shown in perspective. Two units of the type shown in FIG. 1 are combined here to form a tire washing plant with a longer travel path.

FIG. 4 shows an enlarged fragment of the area B framed with dashed lines from the top view of the grid structure according to FIG. 2 . a). One of the wash water pipes carries six nozzle modules, which are releasably fastened to the wash water pipe with screws. Each of the nozzle modules has three nozzles. The nozzle cross-section of the nozzle modules arranged in the middle is designed to be larger than the nozzle cross-section of the nozzle modules arranged at the edge. The nozzle modules are arranged on an inclined surface of the washer water pipe, so that the nozzles of each of the three nozzle modules visible here have a jet axis with a direction in the direction of travel of the vehicle to be washed component, while the other three nozzle modules generate water jets with a directional component opposite to the direction of travel.

The pipe direction u of the washing water pipe 30 is drawn as an arrow.

FIG. 5 shows the pipe direction u of the cleaning water pipe in the previously described Cartesian coordinate system with the axes x, y and z. The axes x and y lie in the plane of the diagram, while the z-axis is perpendicular to the plane of the diagram. The diagram plane of the figure corresponds to plane E1. The projection Α' of the nozzle axis A is likewise drawn, perpendicular to the tube direction u and inclined towards the z direction. Figure 5. a) shows the situation for the pipe direction u of the washer water pipe 30 in the tire washing device according to the invention. The vector components u _x and u _y of direction u are plotted in the direction of the x and y axes. A notable feature of this embodiment is the vector component u _y not equal to zero. The projection A' of the nozzle axis A and thus also the nozzle axis A drawn in FIG. 5 a) in the xy plane thus obtains a component in the x direction. The angle α between u and y deviates here from a right angle. Figure 5.b) shows the situation for the pipe direction u of the washer water pipe 3 from a tire washing installation according to the prior art. The direction u is in the direction of the x-axis and has no vector component in the y-direction. The nozzle axis A and its projection Α' therefore also do not have an x component. The angle α between u and y is in this case a right angle.

In Fig. 6 the grid structure of an embodiment of a tire washing plant according to the invention is shown in side view (Fig. 6.a) and front view (Fig. 6.b). The pipe direction of the rinsing water pipe corresponds to the situation shown in FIG. 5 . a), ie the pipe direction u of the rinsing water pipe 30 forms an angle α which is not visible in the illustration with the direction y. Figure 6 illustrates the effect of tube orientation according to Figure 5.a). The wheels 20 of the axles of the vehicle to be washed are drawn with dotted lines. The position of the wheel 20 is an exemplary selected position as it is achieved during the course of the cleaning process. The nozzles are drawn as points on the wash water pipe 30 . A series of nozzles on the washer water pipe 30 draws a water jet 33 which hits the wheel 20 and the axle in this position. The direction y is in the rolling direction of the tires of the vehicle to be washed. The washing water pipe 30 with nozzles is supported on a longitudinal support structure 32 and extends parallel to the plane E1 and transversely to the direction y. The pipe direction u of the washing water pipe 30 has a vector component u _y in the y direction. It can be seen from the obliquely running water jet 33 in FIG. 6 a ) that the nozzle axis A is inclined towards the surface normal z. A and z are not drawn here for reasons of clarity, but their directions can be deduced from the plane El and the position of the water jet.
