Description

Technical Field

[0001] The invention belongs to the technical field of car side cleaning, in particular to an adaptive cleaning device for the car side of a train. Background Art

[0002] In the field of railway transportation, the cleaning and maintenance of train skins (i.e. railway freight cars) are key links to ensure the safe transportation of goods and the long-term use of cars, especially in the transportation of bulk goods such as coal, ore, and grain. At present, car tippers are generally used for car unloading operations. During the unloading process, the maximum rotation angle is only 165 to 170 degrees. In addition, the reinforcement ribs of the car wall panels cause the wall panels to be uneven and the pressure beams are blocked, so that the coal inside the car cannot be completely unloaded. In addition, sometimes due to the influence of climate, the coal is relatively wet and easy to stick to the bottom of the car and the wall panels, so that a large amount of cargo residue and dust often remain in the car. The residual coal on the bottom of the car ranges from tens of kilograms per car to hundreds of kilograms. These residues may not only contaminate the subsequent loaded goods, but also affect the load-bearing efficiency of the car. In extreme cases, too much residue may also affect the sealing performance and structural safety of the car.

[0003] The existing cleaning work of train wagons mostly relies on manual or simple mechanical tools, which is inefficient and labor-intensive. There is insufficient lighting for working at night, and there are certain safety risks in getting on and off the wagons. The working environment is poor and it is difficult to recruit personnel. The air blowing method is likely to cause a large amount of dust pollution, and the limited wind force makes it difficult to adapt to wet and sticky materials. At the same time, the water jet cleaning method requires the configuration of a sewage recovery and treatment system, which is likely to cause the risk of pipeline blockage and water leakage. Therefore, an adaptive cleaning device for the side of a train wagon is proposed, which has the effect of improving cleaning efficiency and safety and environmental protection.

The rotation of the driven bevel gear will drive the sweeping brushes on both sides of the same driven gear to rotate in the direction of approaching each other. At this time, the vehicle side body will slowly move from the cleaning shell to the suction shell, so that the residue inside the vehicle side body will gradually gather to the center position under the rotation of the two groups of sweeping brushes. At the same time, the rotation of the driving gear will drive the transmission rod to rotate through the pulley and the first belt.

Finally, these residues will gather in the negative pressure groove. At this time, the negative pressure system is started to generate negative pressure so that the residue in the negative pressure groove is sucked out through the telescopic tube and the suction tube, so as to avoid the dust caused by large-scale and small-scale suction, and at the same time, the cleaning efficiency can be improved.
