Disclosed is a telescopic type collision energy absorption device for a rail vehicle, which includes two sets of mechanisms functioned individually. The two sets of mechanisms are mounted respectively on either side of end portion of the vehicle. Each set of the mechanism includes an anti-climber, an energy absorption circular tube, pull rings, cutters, cutter fixing blocks, a mounting base, a cutter base, a guide cartridge, a double-acting type air cylinder, a base, bolts, torsional springs, pins, locating slots, a double-acting type solenoid valve, a controller and air storage tank. When the energy absorption device is in a non-operating state, the double-acting type air cylinder is in a state of tension where it pulls the energy absorption circular tube in such a way that the energy absorption circular tube is retracted into the interior of the guide cartridge, the cutters are pressed against the outer wall of the energy absorption circular tube. Before a collision of the vehicle, the double-acting type air cylinder under the effect of the high-pressure air pushes the second tube in such a way that the second tube is ejected outwards, the cutters are pressed against the locating slots of the energy absorption circular tube under the effect of spring force. The cutters cut the energy absorption structure and absorb the energy when the energy absorption circular tube is subjected to an external force and retracts towards the interior of the guide cartridge.
