The present invention relates to a vehicle underbody and a wheel auto chuck system of a large vehicle that prevents the pipes and the pump from being damaged by preventing the washing water pipe and the pump from being damaged.

In general, when a construction vehicle entering a local construction site or a large-scale land construction site runs in the city without washing wheels, it causes air pollution and affects the surrounding environment. Must clean the wheels and underbody.

In the conventional method of washing the underbody and the wheel. (A) How to clean the body and wheels by making several round trips to vehicles with soil and sediment in the pools where water is accumulated and (B) Washing only the wheels by allowing the vehicle to travel back and forth over the bales of water and (C) The method of washing the car body and the wheels by using high pressure water was mainly used.

However, in this conventional method, (a) and (b) have a problem that the soil is buried more than it is improved after several times of use in a very formal method rather than improving the toshi. In this case, clean washing is possible, but not only a large amount of water is consumed, but the sewage due to the sewage or on the road there was a problem that would rather cause adverse effects.

On the other hand, Japanese Laid-Open Utility Model Publication No. 58-28049 (published on Feb. 23, 1983) discloses a tire support roller group, a washing water spray device for the left and right tires of a vehicle supported thereto, and a departure from the tire. In a tire washer having a storage tank for one dirt and a vane device for discharging the sedimentary dirt at the bottom of the storage tank to the horizontal side, the storage tank is lowered in its left and right walls in the rotational axis direction of the tire support roller group.

As the present invention is constructed as shown in Figure 9 is used as embedded in the concrete in the construction site as shown in the prior art, the detailed description thereof will be omitted, and the operation relationship of the present invention according to the accompanying drawings in detail The explanation is as follows.

When the vehicle loaded with the soil at the construction site enters the vehicle entry part 41 of the main frame 40, and the front wheel of the vehicle enters the exit side roller 50b past the entrance side roller 50a, Due to the operation lever 410 is installed between one side of the outlet roller (50b) is lowered, whereby the operation switch 400 is "on" state, the drive control unit 500 detects this pump 80 And drive the conveyor driver 100 and the roller driver 60 in sequence. At this time, the pump 80 supplies the water in the water tank 30 to the washing water pipe 70, the washing water supplied is a high-pressure spraying the lower body of the vehicle body and the wheels through the injection nozzles 71 at various angles to perform the washing operation. At the same time, the roller drive unit 60 rotates the inlet and outlet side rollers 50a and 50b in one direction, so that the front wheels of the vehicle are idling by the outlet side roller 50b and the washing operation is evenly performed. It is a time set by the control part 500, and during this time, the operation indicator 600 remains in the lit state.

After the set washing time has elapsed, when the operation indicator 600 is turned off, the vehicle driver checks this and advances the vehicle slightly so that the rear wheels are positioned on the rollers 50a and 50b. In the same manner as in the cleaning of the operation switch 400 is turned back on "on" while operating the pump 80 to spray the water in the water tank 30 spray nozzle 71 to the lower body and the rear wheel at various angles By operating the roller drive unit 60 so that the inlet and outlet side rollers 50a and 50b are rotated, the rear wheels are evenly washed. The washing time and the lighting state of the operation indicator 600 are also cleaned of the front wheels. Same as poems.

The present invention operated as described above, because the guide pipe 200 prevents the vehicle body from hitting the wash water pipe 70 or the pump 80 due to the carelessness of the driver when entering the vehicle, in particular in the present invention the injection nozzle (71) ) Has the advantage of not to break.
