Multistage collision energy absorption rail guard

Abstract

The invention relates to a multistage collision energy absorption rail guard which mainly comprises a first-stage hydraulic buffer energy absorption module, a second-stage friction energy absorption module, a third-stage aluminum honeycomb energy absorption module and a fourth-stage energy absorption pipe energy absorption module. All stages of the modules are sequentially installed from front to back. The rail guard can be widely applied to the front end of a train. When the rail guard collides with an obstacle, all stages of the energy absorption modules can deform to absorb energy according to a set collapse sequence, the collapsing energy absorption module at a certain stage or a component is easy to replace, and the interchangeability and the use rate of components are greatly increased.

Description

technical field [0001] The invention relates to an energy-absorbing obstacle remover, in particular to a multi-stage collision energy-absorbing obstacle remover, belonging to the technical field of rail vehicles. Background technique [0002] The obstacle remover is an important part of the passenger and freight locomotive, which is fixed at the front end of the locomotive and is mainly used to remove obstacles in front of the track. The traditional obstacle remover mostly adopts an integrated structure. The front part of the obstacle remover is a panel, and the panel has a single structure welded by a corresponding bracket. The bracket and the car body are connected by bolts. The current type of obstacle remover is generally It does not have the function of absorbing energy. With the popularization of motor vehicles and the improvement of running speed, the obstacle remover is more likely to be deformed or even damaged when it collides with obstacles. Since the ordinary ob...

The traditional obstacle remover mostly adopts an integrated structure. The front part of the obstacle remover is a panel, and the panel has a single structure welded by a corresponding bracket. The bracket and the car body are connected by bolts. The current type of obstacle remover is generally Does not have energy-absorbing function

With the popularization of motor vehicles and the improvement of running speed, the obstacle remover is more likely to be deformed or even damaged when it collides with obstacles. Since the ordinary obstacle remover is a welded structure, it is not easy to disassemble and replace when some parts are damaged. At this time, it needs to be repaired as a whole or replace, resulting in wastage of undamaged parts
