Abstract

The invention discloses a planing energy-absorbing climb-up prevention device and a railway vehicle. The planing energy-absorbing climb-up prevention device comprises climb-up prevention teeth, a planing pipe, a base and a guiding piece, wherein one end of the planing pipe is rotatably connected with the climb-up prevention teeth; a guiding groove is formed in the planing pipe and is spirally formed in the planing pipe in the axis direction of the planing pipe; the base is connected with the other end of the planing pipe in a sliding manner; a planing cutter is arranged on the base and contacts with the planing pipe, and the planing pipe is cut when impact force reaches a predetermined value; and the guiding piece is clamped in the guiding groove and can be slid along the guiding groove when the impact force reaches the predetermined value. By adopting the planing energy-absorbing climb-up prevention device, the technical problem that a planing energy-absorbing climb-up prevention device in the prior art cannot effectively meet higher requirements on energy absorption capacity of the train is solved.

Description

technical field [0001] The invention belongs to the technical field of buffer energy-absorbing devices, and in particular relates to an anti-climbing energy-absorbing device and a rail vehicle. Background technique [0002] With the rapid development of domestic rail transit, the speed of vehicles is getting faster and faster, and the safety of vehicles is getting more and more attention. The safety of passengers must be considered to the greatest extent during the operation of vehicles. When a vehicle collides, it is necessary to consider how to absorb the collision energy and prevent the vehicle from climbing up. [0003] At present, rail vehicles are generally equipped with energy-absorbing mechanisms, and there are many types of structures, such as planed tube type, crushed type, modified form, and steel plate modified form. Comprehensive comparison shows that the overall performance of planing energy-absorbing anti-climbers is relatively excellent. As the running spee...
