The invention provides a rail train anti-creeper and a rail train. The rail train anti-creeper comprises an anti-creeper body, an opening is formed in one end of the anti-creeper body, and a cavity communicating with the opening is formed in the anti-creeper body; the rail train anti-creeper further comprises an energy absorption part which is arranged in the cavity and can extend out relative to the anti-creeper body; a triggering mechanism which is arranged in the anti-creeper body and located at the rear end of the energy absorption part, wherein the triggering mechanism is suitable for triggering the energy absorption part to pop out of the anti-creeper body; and a stop piece arranged on the outer side wall of the anti-creeper body; wherein the energy absorption part is provided with a first position and a second position relative to the anti-creeper body, at least part of the energy absorption part is located in the anti-creeper body at the first position, and at the second position, the energy absorption part extends out of the anti-creeper body and is locked at the second position through the stop piece. The structure can break through the limitation of installation and deformation space of an energy absorption device at the front end of a vehicle body, and the energy absorption performance of the vehicle is greatly improved.
Description
technical field [0001] The invention relates to the technical field of rail train safety, in particular to a rail train anti-climbing device and a rail train. Background technique [0002] As the process of urbanization continues to strengthen, the passenger flow of urban rail transit continues to increase, and the departure interval continues to shrink. The safety and reliability of vehicles during operation is the primary concern of production and operation units and the public. While further strengthening the active safety protection measures of urban rail vehicles to reduce the occurrence of collision accidents, it has become the current research and development time for rail trains to study how to improve the crashworthiness of rail trains from the perspective of passive safety protection and to protect the safety of drivers and passengers as much as possible. hot issues. [0003] Restricted by the structural characteristics of urban rail vehicles, the requirements for...
