Description
Technical Field
The invention belongs to the technical field of rail vehicle cleaning equipment, and particularly relates to all-dimensional self-adaptive mobile cleaning equipment for a rail vehicle.
Background
With the remarkable improvement of the national overall living standard, people have higher requirements on comfort and convenience for the outgoing riding vehicles, and the characteristics of high speed motor train units, such as rapidness, convenience and comfort, are just in line with the travel requirements of people. Meanwhile, in view of the great breakthrough of China in the high-speed motor train unit technology and the great investment in the high-speed train network construction, the high-speed train gradually becomes a main carrying mode of railway passenger transport in China. However, with the use of high speed trains, problems with routine maintenance and cleaning work have also arisen. When the train runs in the wild at high speed, dust, winged insects and the like in the air collide with the surface of the train, are easy to adhere to the surface of the train, and are difficult to clean. In order to ensure the normal running of the train, the daily cleaning work of the train is very important, but in the actual cleaning process, the train head and the train roof are curved surface shapes, so that the existing cleaning device cannot effectively clean the curved surface parts.
Currently, no omnibearing self-adaptive track cleaning product exists in the market, most of related track cleaning equipment patents are limited to frame type cleaning equipment and vehicle body side surface cleaning devices, and effective cleaning of curved surface parts (such as a vehicle head and a vehicle roof) of a vehicle body is difficult. In the patent of CN204978582U, a cleaning device with a large frame is disclosed, and the cleaning devices such as cleaning nozzles are all concentrated on the frame, so that the cleaning device can be moved by using the guide rails on two sides to clean the train on the track. However, due to the large size of the frame, the flexibility of the equipment is limited, the cost is high, only the side surface and the skirt plate of the vehicle body can be cleaned, and the application is limited to a certain extent. In a practical patent number CN202080250U, a mobile cleaning apparatus is described. The cleaning equipment is characterized in that a large rolling brush is arranged at a work execution part of the cleaning equipment, the execution part is arranged on a movable trolley, and the trolley is pushed to drive the execution part to clean the trolley. The device has higher flexibility, but cannot realize the cleaning operation of the vehicle roof and the vehicle head. Patent number CN205468977U relates to a mobile cleaning machine. The brush roller of the cleaning machine can be contracted above the trolley after the work is finished, so that the whole occupied space is greatly saved, and the whole cleaning requirement can not be met. In view of the defects of the prior cleaning equipment, a novel cleaning equipment is designed to solve the problems of the omnibearing and curved surface cleaning of the railway vehicle, and has very important practical engineering significance.

The working principle of the omnibearing self-adaptive movable cleaning apparatus for the railway vehicle of the present invention is described in detail below with reference to fig. 1 to 6.
Before the cleaning apparatus of the present invention is started, it is confirmed that the batteries 1 to 6 in the vehicle 1 are in a full state. The driver starts the vehicle 1 to run beside the train, parallel to the train. The turntable driving motor 1-4 and the hydraulic driving motor 1-2 are started, the turntable 1-3 is rotated, the hydraulic lever group 2-3 is controlled, the supporting arm 2 generates directional motion, meanwhile, the servo motor group 3 is controlled, the posture of the cleaning head 4 is regulated, finally, the brush head mechanism 5 reaches a proper position, and meanwhile, the rolling brush 5-4 contacts the surface of a train body under proper pressure. And starting a valve to enable the cleaning head 4 to spray cleaning liquid, and simultaneously starting the disc-type motor 5-3 to drive the rolling brush 5-4 to rotate to start cleaning work.
After the cleaning head 4 starts to operate, the vehicle 1 is started to run at a uniform speed in a straight line in a direction parallel to the train. When the curved surface perpendicular to the running direction of the carrier vehicle 1 is changed, the support rod part 5-1 and the support head part 5-2 are rotated relatively, and the two springs 5-5 generate return moment, so that the self-adaptive adjustment between the rolling brushes 5-4 is realized, the brush group 4-3 of the cleaning head 4 can be well attached to the changed curved surface, and a better cleaning effect is obtained. When the curved surface parallel to the running direction of the carrier vehicle 1 is changed, the curved surface change condition is collected by means of the distance sensor 4-4 on the cleaning head 4, and the curved surface change rate is calculated by combining the travel change of the shock absorber 4-2, so that the servo motor unit 3 is controlled in real time to adjust the posture of the cleaning head 4, the optimal cleaning angle is ensured, and meanwhile, scratch is prevented. After the cleaning is finished, an operator only needs to retract the whole cleaning device according to the set degree, drive back to the parking garage for charging and add cleaning liquid, and then the next train can be cleaned.
The whole cleaning process of the equipment is completed in a self-adaptive way, an operator only needs to monitor the running condition and prevent accidents, so that the equipment is convenient, efficient and flexible to clean and has important practical value.

the brush head mechanism (5) comprises two rows of a plurality of independent rolling brushes (5-4), and a bracket rod part (5-1) and a bracket head part (5-2) of the brush head mechanism can rotate relatively, so that the rolling brushes can be favorably attached to the curved surface shape of the outer surface of a train; meanwhile, the springs (5-5) are arranged at the two ends of the support rod part (5-1) and the support head part (5-2) and used for correcting the relative positions of the two parts;
the cleaning head (4) is provided with a shock absorber (4-2) and a distance sensor (4-4), and the servo motor unit (3) is controlled to adjust the posture of the cleaning head (4) by combining the feedback data of the shock absorber and the distance sensor, so that the completion of the omnibearing self-adaptive cleaning work of the train surface is ensured.
