Description

[Detailed Description of the Invention] The present invention relates to a lower part cleaning device for automobiles and other vehicles.

Conventionally, for example, as a lower part cleaning device for an automobile, a cart equipped with an injection nozzle that sprays cleaning liquid upward is movably mounted on the floor along a guide rail laid on the floor. It is known that the lower part of a car that has been lifted up is sequentially washed as the trolley moves.

However, this conventional device uniformly cleans the underside of the automobile, and therefore has the disadvantage that the sprayed cleaning liquid does not reach thoroughly in congested areas, such as the inside of the wheel wells after the wheels have been removed from a large vehicle such as a truck, leaving areas uncleaned.

The purpose of the present invention is to provide a lower part cleaning device that eliminates such drawbacks.The main feature of this invention is that the cart is further provided with a position detection device along with an auxiliary injection nozzle, and a The opening and closing of the on-off valve interposed in the pipe is controlled by the output signal of the position detection device.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 indicates the floor surface of the washing area, 2 indicates a guide rail laid on this, and 3 indicates a trolley, which is supported by drive wheels 4 on both sides and a floating wheel 5 at the center of the front end. A guide wheel 6 fixed to the drive wheel 4 of is engaged with the guide rail 2,
The truck 3 is made to move forward or backward on the floor 1 along the guide rail 2 by forward or reverse rotation of the driving wheels 4, 4.

Reference numerals 7a and 7b indicate injection nozzles, and these injection nozzles 7a and 7b are, for example, concentrated nozzles that spray cleaning liquid in a concentrated manner, and 7c and 7d indicate auxiliary injection nozzles arranged on the left and right sides of the injection nozzles 7a and 7b. These auxiliary injection nozzles 7c, 7
For example, d is a wide-angle nozzle that sprays the cleaning liquid in a wide direction, and all of these nozzles 7a, 7b, 7
c and 7d are provided at the tip of a swing arm 16 swingably attached to the cart 3 so as to be swingable back and forth and left and right, and when driven by a motor connected to the root of the swing arm 16, the nozzle 7a ,7b,
7c and 7d reciprocate to the left and right of the cart 3 at the same time.

8a, 8b, 8c, 8d are the nozzles 7a, 7
Cleaning liquid piping passing through b, 7c, and 7d, 9a,
9b, 9c, 9d are these pipes 8a, 8b, 8
On-off valves, ie solenoid valves, 10 interposed in c and 8d, respectively.
indicates a position detecting device, and the position detecting device 10 consists of a diagonal switch 10a provided on the truck 3 and a plurality of actuating pieces 10b for actuating the same, and these actuating pieces 10b can be attached to any position on the floor surface 1. It is.

Reference numeral 11 indicates a self-holding circuit composed of relays and others, 12 a high-pressure hose for cleaning liquid, 13 a hose reel thereof, 14 a cab tire cord, and 15 a cord reel thereof.

Next, the operation will be explained. For example, as shown in FIG. 5, the truck A is lifted above the floor 1 of the washing area by a lift and the wheels are removed. and actuating piece 10
b are attached to the floor surface 1 in front and behind the wheel attachment point as shown in the figure. The rear truck 3 is then moved along the guide rail 2 in the direction of the arrow from the position shown by the dotted line. During this movement, the swing arm 16 is swung to cause the nozzles 7a, 7b, 7c, and 7d to reciprocate left and right, and the electromagnetic valves 9a and 9b are opened to inject cleaning liquid from the injection nozzles 7a and 7b.
In this way, the lower part of the truck A is sequentially cleaned by the cleaning liquid, and when the truck 3 reaches a location B such as the inside of the tire house of the front wheel, the micro switch 10a is activated by the actuating piece 10b, and the self-holding circuit 1 is activated.
1 is self-retained, and the solenoid valves 9c and 9d are opened to inject cleaning liquid from the auxiliary injection nozzles 7c and 7d, thereby intensively cleaning the inside of the wheel housing and other parts. Then, the trolley 3 moves further and the micro switch 10a is actuated by the next actuating piece 10b to release the self-holding of the self-holding circuit 11, and the solenoid valves 9c and 9d are closed to open the auxiliary injection nozzle 7.
The injection of cleaning liquid from c and 7d stops. Thereafter, washing is performed as before, and cleaning liquid is injected from the auxiliary injection nozzles 7c and 7d as well as from the point B, such as the tire house of the front wheel, to the point C, such as the inside of the tire house of the rear wheel of the trolley 3. Then, intensive cleaning is also performed, and then the conventional cleaning is performed again to complete the cleaning of the entire lower part of the automobile. The cart 3 is then returned to its original position. Therefore, areas such as the interior of the tire house, which are difficult to clean as in the case of a truck, can be thoroughly cleaned by intensive cleaning.

In the above embodiment, the position detection device 10 is composed of a micro switch 10a and an actuating piece 10b which can be attached to any position.
However, the detection device is not limited to this, and the detection device may include, for example, a timer that sets the timer by counting backwards the time to a set position by keeping the moving speed of the trolley 3 constant, or a light emitting element and a light receiving device. The element is placed opposite the set position,
Any method may be used, such as a light-emitting element and a light-receiving element that block light when it passes between these elements, or a computer that programs a set position in advance and activates it when the position is reached.

Further, regarding the nozzles, the present invention is not limited to the above-mentioned embodiments, but may be arranged in various ways depending on the object, and some of them may be used as auxiliary injection nozzles.

In this way, according to the present invention, the trolley is further equipped with an auxiliary injection nozzle and a position detection device, and when the trolley moves to an area in the lower part of the vehicle where conventionally there would be unwashed parts, the position detection device detects the location. In addition to the injection of cleaning liquid from the conventional injection nozzle, there is a concentrated injection of cleaning liquid from the auxiliary injection nozzle, so that the entire lower part of the vehicle is thoroughly cleaned and there are no spots left unwashed.
In addition, since the position detection device detects a predetermined location and the auxiliary injection nozzle performs intensive cleaning only on that location, the consumption of cleaning fluid can be minimized. It has effects such as being applicable to vehicles as well.
