Anti-climbing device for rail vehicle

Abstract

The invention relates to the field of railway traffic equipment, in particular to a railway vehicle anti-climbing device. The railway vehicle anti-climbing device comprises a fixing pipe, a turnover energy absorption pipe and an anti-climbing engaged tooth. The anti-climbing engaged tooth is fixed to one end of the turnover energy absorption pipe. The other end of the turnover energy absorption pipe is fixed to one end of the fixing pipe, and the other end of the fixing pipe is fixed to the front end of a vehicle body. The turnover energy absorption pipe is contained in the space formed by outward extending of a pipe cavity of the fixing pipe, the distance between the outer wall of the turnover energy absorption pipe and the inner wall of the fixing pipe is longer than the wall thickness of the turnover energy absorption pipe in the direction perpendicular to the movement direction of the vehicle body. In the collision process, the wall thickness of the fixing pipe can be multiplied after the turnover energy absorption pipe of the railway vehicle anti-climbing machine deforms and absorbs energy, so that the capability of resisting climbing a vehicle of the railway train anti-climbing device is improved while the energy absorption effect of the railway train anti-climbing device is ensured.

Description

technical field The invention relates to the field of rail transportation equipment, in particular to an anti-climber for rail vehicles. Background technique As the main form of passenger transport in our country, rail vehicles are particularly important for their safety. In order to ensure the safety of rail vehicles, many advanced active protection technologies are currently used for rail vehicles, but it is still impossible to completely avoid rail vehicle collisions and threaten the safety of passengers. Therefore, while improving the active safety protection of rail vehicles to avoid collision accidents as much as possible, it is also necessary to realize the passive safety protection of rail vehicle structures to minimize the losses caused by accidents. The anti-climber is a core component installed on the front end of the rail vehicle to realize the passive safety protection of the rail vehicle structure. Its function has two aspects: on the one hand, when the rail v...
