A vibration damping device for tunnel traction locomotive

Abstract

A vibration damping device for tunnel traction locomotive includes a first leaf rubber spring assembly disposed between the bogie side plate and the wheelset and for reducing wheel set vibration, a second leaf rubber spring assembly mounted between the bogie and the vehicle body and for reducing vibration of the vehicle body and a cushioning sleeve assembly disposed between the bogie and the traction pin shaft, the first leaf rubber spring assembly includes a first leaf rubber spring and a wedge seat, The wedge-shaped seat is provided with a second inclined surface, and the second inclined surface is provided with a V-shaped groove. The first leaf rubber spring comprises a V-shaped rubber plate, a V-shaped steel plate and an oblique triangular prism. The outer surface of the V-shaped steelplate is slidably matched with the surface of the V-shaped groove, and the oblique triangular prism is fixedly connected with the wedge-shaped bearing seat. The invention can reduce the vibration ofthe wheelset, can provide the flexible connection in the longitudinal and transverse directions of the tunnel traction locomotive, reduces the wear between the wheel and the track, and can prevent thedamage to the bogie and the traction pin shaft caused by the rigid impact.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a vibration damping device for a tunnel traction locomotive. Background technique [0002] With the rapid development of my country's subway and other highway tunnels, the characteristics of long distances and large slopes in the tunnels have become more and more prominent. In tunnel construction projects, various resources such as muck, cement, and segments are transported by tunnels. The traction locomotive is in charge, and the task is very heavy, especially in large-diameter tunnels, the transportation volume of materials has increased greatly, and the tunnel construction has higher and higher requirements for the traction capacity of the tunnel traction locomotive. come higher. However, during the construction and transportation of the current tunnel traction locomotives in tunnels with long slopes, the operators often have fear because of the excessive ...

AI Technical Summary

Problems solved by technology

However, during the construction and transportation of the current tunnel traction locomotives in tunnels with long slopes, the operators often have fear because of the excessive speed of the tunnel traction locomotives, which affects the physical and mental health of the operators; at the same time, the speed of the tunnel traction locomotives Excessive speed will also cause safety hazards to the equipment on the vehicle. The traction pin shaft is subject to a very large impact, especially when the tunnel traction locomotive is turning, the wear between the traction pin shaft and the bogie is increased, resulting in damage to parts , shorten the service life of the parts, and the safety performance of the tunnel traction locomotive is poor. Therefore, a vibration damping device for the tunnel traction locomotive should be provided
