[0034] The present application can be used in the field of cleaning vehicles, and can also be used in other fields applicable to the present application.

[0035] Embodiment 2: Reference Figures 1-5On the basis of improving embodiment 1: a kind of adjusting offset assembly suitable for railway train cleaning car is applied to cleaning car field, in order to ensure the stability of rack 21 during movement, multiple limit seats 24 are slidably arranged on the outer wall of rack 21.The top of these limit seats 24 is slidably provided with a second guide rod 26.The top of second guide rod 26 is fixedly provided with a fixed block 25, and the fixed block 25 is fixedly arranged on one side of limit seat 24.A spring 27 is sleeved on the outer wall of second guide rod 26.Both ends of spring 27 are fixedly connected with fixed block 25 and the side of limit seat 24 close to each other respectively.In this way, when rack 21 moves, it will be subjected to the elastic force of spring 27, so as to keep its stability, and provide reset power when needed.

[0036] In addition, support rods 22 corresponding to extension 23 are fixedly arranged on the outer wall of rotating pipe 5.These support rods 22 are used to support and fix spray head 19, to ensure its stability during rotation.Spray head 19 is rotatably sleeved on support rod 22, which can realize more flexible rotation and water spraying effect.

[0037] Finally, rotating shaft 12 is rotatably arranged on the top and bottom of adjusting frame 10.Both the outer wall of cleaning roller 4 and rotating shaft 12 are fixedly sleeved with first gear 13 engaged with each other.In this way, when rotating shaft 12 rotates, it will drive cleaning roller 4 to rotate through the meshing action of first gear 13.At the same time, a roller 14 is also fixedly sleeved on the outer wall of rotating shaft 12, which can be in rolling contact with the outer side of train when the train moves, so as to keep the relative position between cleaning roller 4 and train stable and improve the cleaning effect.

[0038] In this application, when in use, the vehicle body 1 is opened to the side of the train, and the roller 14 is in contact with the side of the train, then the orientation of the extension 23 and the water pressure are adjusted according to the need for flushing by starting the second motor 16, when high pressure flushing is needed, the second motor 16 is started to drive the rotating pipe 5 to rotate, the rotating pipe 5 rotates to drive the extension 23 to rotate, so that the included angle between the extension 23 and the side of the train is reduced, and the rotating pipe 5 rotates to drive the rack 21 to move through the limit seat 24, the rack 21 moves to drive the rack 21 to move downward through the stepped groove 18, the rack 21 moves downward to drive multiple second gears 20 to rotate simultaneously, the second gears 20 rotate to drive the spray head 19 to rotate, to adjust the number of spray holes, and the water pressure is adjusted by the number of spray holes, then the water pump 6 is started, the water pump 6 can pump the water in the water tank 2 into the rotating pipe 5, and spray out through multiple groups of extension 23 and spray head 19 to flush the train;

[0039] At the same time, the vehicle body 1 is started to move, and the vehicle body 1 can drive the rotating shaft 12 to rotate through the friction between the rolling wheel 14 and the train during the movement of the vehicle body 1, and the rotating shaft 12 can drive the cleaning roller 4 to rotate through the two first gears 13 during the rotation of the rotating shaft 12, and the cleaning roller 4 is moved and cleaned while being washed;

[0040] The standard distance between the vehicle body 1 and the train is a certain distance, and the laser range finder 3 is started to detect the distance between the vehicle body 1 and the train in real time, and the value is transmitted to the control unit in the cab in real time. When the control unit receives the detection data of the laser range finder 3 deviating from the value, the first motor 11 is started through the control, and the first motor 11 can drive the screw rod 9 to rotate, and the screw rod 9 can move on the fixed seat 7 during the rotation, so as to drive the adjusting frame 10 to move, and the adjusting frame 10 can drive the cleaning roller 4 to move, and further make the rolling wheel 14 abut against the side of the train, so that the distance between the vehicle body 1 and the train is kept within the standard distance range in real time.

[0041] When the distance between the vehicle body 1 and the train deviates too much, more than 50-100mm of the standard distance, the alarm information is triggered, and the driver needs to control the cleaning car steering wheel to adjust the position.
