The invention discloses a planing energy-absorbing anti-climbing device and a rail vehicle, comprising: an anti-climbing tooth; a planing pipe, one end of the planing pipe is rotatably connected to the anti-climbing tooth; There is a guide groove, and the guide groove is spirally arranged on the planing pipe along the axial direction of the planing pipe; the base is slidingly connected with the other end of the planing pipe, and the base is provided with Yes, a planing knife, the planing knife is in contact with the planing tube, and cuts the planing tube when the impact force reaches a preset value; a guide, the guide is stuck in the guide groove, When the impact force reaches a preset value, the guide member can slide along the guide groove. The technical problem that the planing energy-absorbing anti-climbing device in the prior art cannot reasonably and effectively meet the higher requirements of trains for energy absorption 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...
