Abstract: An easy-to-maintain frame-type energy-absorption structure, including: a fixing frame, anti-climder which are arranged at the front of the bottom of the fixing frame, energy absorption block which are detachably connected with the fixing frame and the anti-climder respectively, a connecting device for hinging the anti-climder and the fixing frame, and shear pins which are respectively arranged at a junction of the connecting device and the fixing frame, and a junction of the connecting device and the anti-climder. So that changing the traditional whole welded frame type energy absorbing device into an easy-to-maintain frame-type energy-absorption structure, and when a collision occurs, protecting the fixing frame from being damaged, and the energy absorption block can be replaced to achieve reuse it.

Abstract: The present invention discloses a honeycomb type cowcatcher and energy absorber for rail transit vehicles, comprising a high rigidity supporting back frame for cowcatcher and energy absorber, arranged detachably on a frame body of rail transit vehicle; at least one honeycomb type cowcatcher and energy absorber unit fixedly screwed on supporting back frame, applied to absorbing an impact energy generated by collision through plastic deformation; the honeycomb type unit comprises honeycomb structured accommodation cavity, where a honeycomb structure arranged. Through a method of mounting a honeycomb type unit onto the high rigidity supporting back frame, the present invention makes part of energy have been absorbed by the unit before a rigid collision between obstacle and train body happens, thus weakens a relatively large impact afforded by train body, therefore, decreases a damage from obstacle to train body.
