[0002] With the widespread use of bus washing machines, it has indeed played a great role in improving the taste of the city. The buses we see on the roads and highways are as bright and clean as new, but in bus washes, it is found that the bus mirrors are often broken and the paint is often scraped off. Because, in the channel-type bus rapid car wash machine, the car wash machine is generally stationary, and the driver slowly drives the bus into the car wash machine for washing. The quality of washing is largely determined by the driver's driving speed (maintaining a speed of 5 km / h).

[0026] Specifically, the outer surface of the first adjusting rod 18 is threadedly connected to the first slider 20 , and the outer surface of the first slider 20 is rotatably connected to the first adjusting sprocket 21 . The first adjusting sprocket 21 is meshed with the transmission chain 5 .

[0027] In this embodiment, by setting the first adjusting sprocket 21, when the first adjusting rod 18 rotates, the first slider 20 drives the first adjusting sprocket 21 to move, thereby adjusting the tension of the transmission chain 5, thereby conveniently realizing transmission adjustment, reducing equipment downtime, reducing maintenance costs, and improving equipment operation efficiency.

[0028] Specifically, a box body 22 is fixedly connected to the side of the upper surface of the shell 1 close to the traction driven sprocket 10, and a second control rod 23 is rotatably connected to one side of the inner side of the box body 22. One end of the second control rod 23 is fixedly connected to a second hand wheel 24, and the outer surface of the second control rod 23 is fixedly connected to the side away from the second hand wheel 24. The outer surface of the second worm 25 is meshed with a second worm wheel 26.

[0029] In this embodiment: through the setting of the second hand wheel 24, the second hand wheel 24 is fixed to one end of the second control rod 23, which is convenient for operating and controlling it, convenient for hand exertion, and increased convenience of use. Through the setting of the second worm 25 and the second worm wheel 26, under the action of the second worm 25, the second worm wheel 26 drives the second adjusting rod 27 to rotate, playing the role of relay drive. At the same time, the second worm 25 and the second worm wheel 26 can produce a self-locking phenomenon when not in use, so that the position of the second adjusting sprocket 33 is relatively stable.

[0030] Specifically, the interior of the second worm gear 26 is fixedly connected to a second adjusting rod 27, and the second adjusting rod 27 is rotationally connected to the housing 1.

[0031] In this embodiment: through the setting of the synchronous belt 30, the synchronous belt 30 is connected to the inner side of the synchronous wheel 29 on the outer surface of the second adjusting rod 27 and the third adjusting rod 28. Under the action of the second adjusting rod 27, it makes reciprocating motion, which can make the second adjusting rod 27 and the third adjusting rod 28 maintain rotation synchronization, and the two sets of second adjusting sprockets 33 rise and fall in unison, thereby making the tension of the two sets of traction chains 9 can be kept synchronized.

[0032] Specifically, the outer surfaces of the second adjusting rod 27 and the third adjusting rod 28 are both threadedly connected to the second slider 31, the outer surface of the second slider 31 is fixedly connected to the fixing rod 32, and both sides of the outer surface of the fixing rod 32 are rotatably connected to the second adjusting sprocket 33, and the second adjusting sprocket 33 is meshed with the traction chain 9.

[0033] In this embodiment: through the setting of the second adjusting sprocket 33, when the second adjusting rod 27 and the third adjusting rod 28 rotate, the second slider 31 on its outer surface moves up and down through the fixed rod 32, thereby adjusting the position of the second adjusting sprocket 33, so that the traction chain 9 maintains a suitable tension, avoids the traction chain 9 from being too loose, resulting in tooth jumping, loose vibration, reduced transmission accuracy, and may even cause equipment shutdown, and at the same time avoids the traction chain 9 from being too tight. If the traction chain 9 is too tight, it will increase the contact pressure between the chain and the sprocket, resulting in increased wear, reduced transmission efficiency, and may even cause the chain to break. The second adjusting sprocket 33 can effectively avoid this situation and extend the service life.

Baffles 42 are rotatably connected to both sides of the outer surface of the rotating shaft 41, and a roller 43 is rotatably connected to the outer surface of the baffle 42. A torsion spring 44 is sleeved on the middle part of the outer surface of the rotating shaft 41.

[0039] In this embodiment: through the arrangement of the rotating shaft 41 and the baffle 42, the baffle 42 is rotatably connected to the edge of the inner side of the placement box 40 through the rotating shaft 41, and usually protrudes from the placement box 40. Its surface is rotatably connected with a roller 43. When the vehicle is transporting, under the action of the external force of the vehicle, the roller 43 drives the baffle 42 to rotate on the outer surface of the rotating shaft 41 and rotate toward the inner side of the placement box 40. The roller 43 prevents the baffle 42 from being damaged by long-term contact with the vehicle and can adapt to changes in the position of the vehicle.

When the baffle 42 rotates toward the inside of the placement box 40, the rubber rod 45 contacts the sensing piece 47, triggering the car washing machine to operate and wash the vehicles on the conveyor line without manual intervention, which greatly shortens the response time of the equipment and makes the vehicle washing process smoother. The spring 46 facilitates the reset of the sensing piece 47 and can adapt to the positions of different vehicle wheels within a certain range, thereby enhancing the applicability.

[0042] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.
