Buffer protecting system for rail vehicle coupling gear

Abstract

The invention relates to the technical field of rail traffic, in particular to a buffer protecting system for a rail vehicle coupling gear. The buffer protecting system comprises a buffer, a pressuresensor, a locking device, an upper computer and a lower computer; the buffer comprises a buffer body, and the top end and the bottom end of the buffer body are provided with an upper end plate and a lower end plate correspondingly; the pressure sensor is mounted at the bottom of the upper end plate; the locking device is mounted between the upper end plate and the lower end plate and can rotate relative to the upper end plate; the upper computer is connected with the pressure sensor; and the lower computer is connected with the upper computer and the locking device. The buffer protecting system can lock the buffer at the stage of small pressure, the pressure at the stage is counteracted through rigidity of the locking device, the using frequency of the buffer is decreased, the mechanical property of elastic components of the buffer is protected, and the service life of the buffer is prolonged.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail vehicle coupler buffer protection system. Background technique [0002] The buffer is an important part of the rail vehicle coupler. Due to the mechanical vibration generated when the coupler is connected and the vehicle is running, the coupler is easily damaged and malfunctions. The buffer can reduce the mechanical vibration, thereby protecting the coupler and prolonging the service life of the coupler. However, the coupler will continue to vibrate slightly when the vehicle is running, so that the buffer is always in a low-pressure and high-frequency working state. The main buffer components of the buffer are elastic components. Long-term frequent use will reduce the mechanical properties of the elastic components. The cushioning effect of the buffer is not obvious, and the buffering efficiency decreases. Contents of the invention [0003] The invention sol...

Problems solved by technology

[0003] The invention solves the problems in the related art that the elastic elements of the buffers are frequently used for a long time, and the mechanical properties decrease, the buffering effect of the buffers is not obvious, and the buffering efficiency decreases. Stage locking buffer, using the rigidity of the locking device to offset the pressure of this stage, greatly reduces the frequency of use of the buffer, protects the mechanical properties of the elastic element of the buffer, and prolongs the service life of the buffer
