Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicles, in particular to a sandblasting anti-skid device for a rail vehicle and the rail vehicle. Background Art

[0002] At present, for shield tunneling construction in urban tunnels, how to safely and smoothly transport the materials needed during the construction process to the tunnel has become a major problem. At present, most of them use rail locomotives for transportation. After using rail locomotives for transportation, the efficiency of shield construction is greatly improved, the material transportation time is reduced, the construction continuity is guaranteed, and the risk of shield tunneling construction is reduced. When using rail locomotives to transport materials, the safe braking of rail locomotives is the key to shield construction.

[0003] The existing locomotive braking process mainly relies on the locomotive's own braking system and an external anti-slip hook. In actual construction, the humidity in the tunnel is high and the hole is damp. At the same time, during the transportation of materials, water may appear on the track, which can easily cause wheelset slippage, insufficient traction, etc., causing the locomotive to jump off the track or slip.

[0004] In order to prevent the rail locomotive from slipping, a rail train circulating sandblasting system with an existing application number of 202210786151.9 is provided on the locomotive to sandblast the track to prevent slipping. Specifically, the anti-skid sand in the rectangular sand storage box is sprayed onto the track through the sandblasting tube under the action of the delivery pump, thereby increasing the friction between the track and the wheel and achieving an anti-skid effect. On the one hand, the rail train circulating sandblasting system needs to deliver anti-skid sand through a delivery pump, which consumes a lot of energy and has high manufacturing and use costs; on the other hand, the overall structure is complex, and it is inconvenient to disassemble and adjust the water, which is costly; thirdly, sand is easily left in the rectangular sand storage box, and the residual sand may clump. If it is pumped into the sand outlet pipe again, it is easy to cause pipe blockage. Utility Model Content
