Description

[Detailed description of the invention] [Industrial application field] The present invention is a car washing machine that relatively moves a wheel moving trolley that supports the front wheels (or rear wheels) of a four-wheel drive vehicle and a portal car washing machine. In the car wash equipment that
The present invention relates to a car wash device that allows the vehicles to move smoothly and reduces the space required for a car wash.

[Conventional technology]

In conventional car wash equipment in which a gate-type car wash machine and a vehicle moving trolley are moved in opposite directions to wash cars, the front wheels of the car are usually placed on the trolley, and the trolley is pulled by a chain or the like. It is designed to run backwards and forwards.

[Problem that the invention attempts to solve]

In a full-time four-wheel drive vehicle, when the transmission is set to neutral, all wheels spin simultaneously, and if some wheels are prevented from rotating, other wheels will also become unable to rotate.

Therefore, in the above-mentioned type of car wash apparatus, when the front wheels of a full-time four-wheel drive vehicle are placed on the moving trolley and the trolley is moved, the front wheels do not rotate and the rear wheels also do not rotate. As a result, the front wheels may fall off the cart, or the rear wheels may scrape on the floor, making it difficult to wash the car properly.

In order to solve these problems, it is necessary to place all wheels of a full-time four-wheel drive vehicle on a moving trolley. However, if the trolley is configured in this way, its front and rear length will be large, and a large space will be required to place the front and rear wheels parallel to the trolley and drive the vehicle onto the trolley. The venue space will also be large.

[Means for solving problems]

The present invention solves the above-mentioned problems by making a mobile trolley that supports the front wheels (or rear wheels) of a full-time four-wheel drive vehicle so that the wheels mounted on it can freely rotate. Its concrete structure consists of a trolley on which either the front or rear wheels of the vehicle are placed and the vehicle is moved back and forth, and a gate type that can straddle the vehicle and move in the same direction as the trolley. In the car washing device, the car washing device is equipped with a car washing machine and is configured to wash a car by relatively moving the cart and the gate-type car washing machine, wherein the cart is provided with rollers for allowing wheels supported thereto to rotate freely. It has been established.

[Effect]

The wheels of the four-wheel drive vehicle to be cleaned, which are supported on the front and rear rollers of the moving trolley, can rotate freely. Therefore, the other wheels also roll on the floor, and the four-wheel drive vehicle moves smoothly.

〔Example〕

The drawing shows one embodiment of the present invention, in which 1 is the floor of a car wash, 2 is the same wall, and 3 is laid on the floor 1 facing at right angles to the wall 2, and the front end (left end of the drawing) A pair of left and right first rails 4 adjacent to the wall 2 are a known gate-type car wash machine that runs by itself on the first rails 3, 3.

5 is a pair of left and right second rails laid on the floor 1 parallel to the first rails 3, 3 between the first rails 3, 3; This is a trolley for moving the vehicle on which it is riding.

4 and 5 show details of the moving trolley 6. FIG.

This truck 6 has a downward cross-section, and has left and right side rods 16, 16 on which small wheels 15, 15 are pivotally supported on the front and rear inside sides, and a central base plate 17 with its front and rear ends facing each other at angles. The tubes 18 and 19 are connected to each other, and each side rod 16 is connected with the tubes 18 and 19 at the lower rear of the square tube 18 at the front, and at the lower front of the square tube 19 at the rear.
and the base plate 17, there are rollers 20 and 21, respectively.
, and a boarding plate 22 whose upper surface slopes backward and downward is attached to the rear surface of the square tube 19 at the rear.

A chain 8 is routed around a pair of front and rear sprockets 7, 7, which are pivoted between the front ends of the second rails 5, 5 and also between the rear ends, and the cart 6 is engaged with the chain 8. It is worn.

The truck 6 runs back and forth on the second rails 5, 5 by a drive device 10 connected to the front sprocket 7 with a drive shaft 9.

Between the wall 2 and the front sprocket 7, the floor 1 consists of a detection rod 11 whose upper part is close to the wall 2, and a limit switch (not shown) that opens and closes when the detection rod 11 swings. A detection device 12 is installed that stops the drive device 10 when the vehicle moves.

FIG. 1 shows a vehicle 13 in the above-described device of the present invention.
The car wash machine 4 is located at the front end, the trolley 6 is located at the rear end, and the four-wheel drive vehicle 13 to be washed is placed on the upper surface of the rollers 20, 21 in front. A front wheel 14 is supported.

Note that at this time, the front wheels 14 may be in contact with the floor.

The car wash starts, and while the front and top surfaces of the vehicle 13 are washed by the car wash machine 4, the vehicle 13 is washed along with the trolley 6.
When the front wheel 14 is moved forward, the front wheel 14 rolls on the rollers 20 and 21, so that the rear wheel to be driven also moves to the floor 1.
Since it rolls on the top, the vehicle 13 can move smoothly.

As shown in FIG. 2, when the front end of the vehicle 13 comes into contact with the detection rod 11, a command from the detection device 12 causes the
The trolley 6 stops.

Next, while washing the side and top surfaces of the vehicle 13, the car wash machine 4 moves backward as shown in FIG.
returns to the state shown in FIG.

A photoelectric sensor can also be used as the detection device 12.

Instead of the front wheels of the four-wheel drive vehicle 13, the rear wheels may be supported by the truck 6.

[Effect of idea]

According to the present invention, the front wheels (or rear wheels) of a four-wheel drive vehicle supported on the front and rear rollers of the moving trolley can rotate freely, so the other wheels also roll on the floor, causing the four-wheel drive vehicle to rotate freely. Wheel drive vehicles can move smoothly.

Therefore, there is no need to place all four wheels on the trolley, the trolley can be shortened, and the front and back length of the car wash space can be shortened, allowing effective use of the car wash area.

The device of the present invention may also be used in conventional two-wheel drive vehicles.
