[0036] The following will be described in detail with reference to the accompanying drawings. Figures 1-11 The present application will be further described in detail.

[0037] The present application provides a rail vehicle cleaning device, which adopts the following technical scheme:

[0038] Referring to Figure 1 , the rail vehicle cleaning device comprises a sliding mechanism 2 and a chassis 3. The parallel rails are composed of two guide rails 1 in parallel pairing, the sliding mechanism 2 is placed on the parallel rails to slide, the chassis 3 is installed on the sliding mechanism 2, and the vehicle body 4 is installed on the chassis 3.

[0044] With reference to Figure 2 and Figure 6Two ends of the chassis 301 are fixedly connected with driving frames 5 through bolts, the driving frames 5 are connected with a tractor, and the rail vehicle is conveniently driven by the tractor. The driving frame 5 is installed at the center line of the end of the chassis 301, the driving frame 5 is fixedly connected with a connecting block 207 through bolts, the connecting block 207 extends to the contact position of the rail wheel 201 and the guide rail 1, the connecting block 207 is installed with a jet pipe 211, one end of the jet pipe 211 can be directly connected with the end of the shunt pipe 219 through a pipeline, and the other end of the jet pipe 211 faces the surface of the guide rail 1 and the surface of the rail wheel 201.

[0045] When the rail vehicle travels on the parallel track in one direction, the air in the environment flows into the air collecting pipe 215 from the windward pipe 217 on the leeward side of the connecting frame 214, the first air conditioner valve 216 on the leeward side is opened, the first air conditioner valve 216 on the windward side is closed, the air in the air collecting pipe 215 enters the shunt pipe 219 through the three-way pipe 222, and then the air in the shunt pipe 219 is output to the jet pipe 211 on the leeward side through the closed second air conditioner valve 220 on the windward side, the jet pipe 211 on the leeward side blows the surface of the guide rail 1 and the surface of the rail wheel 201, and the impurities are removed before the rail wheel 201 contacts the guide rail 1 in front of the travel path, so that the stability of the vehicle operation is improved.
