Abstract

The invention relates to a coupler buffer device with a cutting type energy-absorbing bumper. The coupler buffer device comprises a coupler head, a coupler body, an energy absorber and a buffer, wherein the energy absorber has a cutting type energy-absorbing anti-collision structure; and one end of the energy absorber is in sleeve connection with the tail part of the coupler body, and the other end of the energy absorber is in rigid connection with the buffer. The energy absorber with the cutting type energy-absorbing anti-collision structure has a structure 1, wherein an energy-absorbing element and a cutter are arranged in an outer sleeve, the cutting edge of the cutter is contacted with the energy-absorbing element, and one end of a cutter rod of the cutter is contacted with the tail part of the coupler body. The energy absorber with the cutting type energy-absorbing anti-collision structure has a structure 2, wherein the outer sleeve and an inner sleeve form an interlayer barrel structure with lower inside and higher outside, and the energy-absorbing element is arranged in the inner sleeve; a threshold spring is arranged between the outer sleeve and the inner sleeve, and one end of the threshold spring is contacted with the tail part of the coupler body; the inner wall of the inner sleeve is provided with a guide plate to form a guide cavity; a blade is arranged on the middle part of the cutter rod, and the cutting edge of the blade is contacted with the energy-absorbing element; and the end of the cutter rod facing the buffer passes through a pre-tightening piece arranged on the rear tail part of the guide plate, and an idle stroke gap is formed between the free end of the cutter rod and the tail part of the coupler body.

Description

Technical field [0001] The invention relates to a coupler buffer device with a cutting type energy-absorbing anti-collision device with anti-collision function applied to rail trains. Background technique [0002] Currently, rail train sets are connected by coupler buffer devices with energy-absorbing anti-collision devices. Take the CG-5 close-coupled subway coupler buffer device as an example. It integrates the functions of mechanical connection and air path connection, and can be automatically or manually unhooked. The energy absorber is composed of two parts: an elastic mortar buffer and a crush tube. The elastic mortar buffer is used to absorb the impact energy of the vehicle during normal connection and operation, and the crush tube is used to absorb the impact energy of the vehicle in an accident collision. The elastic mortar buffer is a recoverable deformation energy absorbing device, and the crush tube is an irreversible deformation energy absorbing device. The tail pa...
