Abstract

A straddle-type threaded self-locking track automatic compensation backing plate, characterized in that a positioning protrusion is arranged on the base, a groove matching the positioning protrusion is opened on the cover plate, and the base and the cover plate pass through the positioning protrusion , Groove matching; the driving gear is installed in the inner cavity of the base, and a plane scroll spring is arranged between the bottom of the driving gear and the base; a gasket is placed on the driving gear, and there are evenly distributed installation holes on the gasket. The lower end of the gear is set in the installation hole, the driven gear meshes with the internal teeth of the driving gear, and the upper part of the driven gear is connected with the cover plate through threads; a reset gear is arranged on the base of the outer tooth surface of the driving gear, and the reset gear and the driving gear The outer teeth mesh. The straddle-type threaded self-locking track automatic compensation backing plate of the present invention has the characteristics of simple structure and reliable operation, and it can realize automatic stepless adjustment. It is used on the ballasted track bed of the railway line structure and can solve the uneven settlement of the line. causing irregularities.

Description

technical field [0001] The invention relates to a straddle-type threaded self-locking track automatic compensation backing plate. Background technique [0002] The railway line structure is composed of lines (subgrade lines), bridges, tunnels, and stations. The track structure of the line can be laid with ballasted tracks and ballastless tracks according to the differences in railway grades and technical standards. The stiffness of different line structures is significantly different, causing the displacement response of the rail surface to be inconsistent when the train passes. At the same time, the foundation settlement of different structures is not uniform, and deformation is easily generated near the transition point, resulting in bending of the rail surface. When the train passes by at high speed, the dynamic interaction between the vehicle and the line is intensified, causing serious irregularities on the track surface, accelerating the deterioration of the line state...
