Abstract

The invention provides an energy-absorbing and anti-creeping device, and belongs to the technical field of passive safety of rail trains. The front end of an energy-absorbing pipe is fixed with the inner side of an anti-creeper; a cross guide rod hole is formed in the center of a mounting base; the bottoms of tile-shaped cutter mounting seats are fixed with the mounting base; the tile-shaped cutter mounting seats are fixedly connected with the rear part of a semi-ring cutter by bolts; a semi-dovetail structure of an inside diameter of a rear section of the energy-absorbing pipe is matched with a blade point of the semi-ring cutter; the tail end of the inside diameter of the energy-absorbing pipe clings to an oblique plane of the front end surface of an expansion guide ring; induction grooves and guide rod grooves are formed in an inner wall of the energy-absorbing pipe; the center of the inner side of the anti-creeper is fixed with one end of the guide rod; the other end of the guide rod penetrates through the guide rod hole. The device is mainly used for passive safety of rail trains.

Description

technical field [0001] The invention relates to the technical field of rail train passive safety. Background technique [0002] With the vigorous development of my country's high-speed railway industry, the speed and density of trains are also increasing. The issue of train collision safety has been widely concerned, and the study of passive safety performance of trains has become one of the hot topics. The energy-absorbing anti-climbing device is an important part of the passive safety of rail trains. The special energy-absorbing anti-climbing device can absorb most of the energy of the train during the collision process, so it can greatly improve the passive safety performance of the train. Its working principle is to absorb The energy components undergo irreversible plastic deformation or destruction during the collision to absorb the collision energy. [0003] Existing energy-absorbing devices for rail trains mostly use crush-type energy-absorbing structures. For exampl...
