A coupler buffer device for locomotive traction connection

Abstract

The present invention relates to the technical field of coupler buffers, and discloses a coupler buffer device for traction connection of locomotives, comprising a first buffer member and a second buffer member, wherein the first buffer member includes a first group of buffer sleeves, a second buffer member. A first roller is fixedly installed in the middle of one end of a group of the buffer sleeves, and the second buffer member includes a second group of buffer sleeves. The coupler buffer device used for locomotive traction connection, for the arrangement of the first roller and the second roller, when there is still a large impact force between the buffer sleeves after the initial buffering effect, the two groups of buffers will be driven as a whole. The sleeve moves inward and makes it staggered under the impact of the adjacent locomotives, so as to use its own gravity to buffer the impact force between the adjacent two sets of locomotives, so as to reduce the impact between the adjacent two sets of locomotives. A secondary buffering effect is formed, thereby effectively improving the buffering strength that the coupler buffering device can bear and act as a buffer.

Description

technical field [0001] The invention relates to the technical field of coupler buffers, in particular to a coupler buffer device used for locomotive traction connection. Background technique [0002] The coupler buffer is an important part of the interconnection of multiple groups of locomotives. The coupler mainly transmits the traction force and maintains the gap between the locomotives without power output; and the buffer is mainly to ease the progress between the multiple groups of locomotives. The longitudinal impact force and vibration generated in the process of deceleration and braking, thereby reducing the damage to the vehicle structure and the cargo it carries. [0003] Among them, the buffering effect in the existing coupler buffer is achieved by compressing the elastic element to relieve the impact force, and the frictional damping of the elastic element during the deformation process is used to absorb the impact energy. However, this buffering method In the fa...

Problems solved by technology

[0003] Among them, the realization of the buffering effect in the existing coupler buffer is to alleviate the impact force by means of compressing the elastic element, and to absorb the impact energy by using the frictional damping of the elastic element during the deformation process. However, this buffering method In the face of a locomotive with a huge impact force, the damage to the compressed elastic element on it is relatively large, and it is difficult to effectively withstand the large impact force, making it a vulnerable part in the coupler buffer device, which needs to be regularly repaired Detection and replacement not only increases its cost during use, but also increases the workload of maintenance personnel
