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.
