Abstract

A rail vibration damping fastener is disclosed in this paper, which comprises a cushion plate, an elastomer, a support plate, a positioning block and a fastening mechanism. The pad plate is provided with a positioning column, the positioning block is provided with a first through hole, and the positioning block is sleeved on the outside of the positioning column through the first through hole. Thefastening mechanism comprises a fastener and a locking cover plate, wherein the fastener is connected with a positioning post, and the fastener presses the positioning block through the locking coverplate; One side of the support plate is connected with the elastomer, the elastomer is fixed at the rail waist of the rail, and the other side of the support plate is abutted on the positioning block; The contact surface between the support plate and the positioning block is an inclined surface, and the top end of the inclined surface is inclined to the side close to the rail; The application canbe applied to the technical field of rail transit, and the application can effectively solve the problems existing in the prior art, and can realize the convenient installation operation of the positioning block, so as to provide the elastomer with sufficient pressing force; Furthermore, the composition of the existing rail vibration damping fastener can be optimized, and the convenient installation and maintenance operation can be realized.

Description

Technical field [0001] This application relates to, but is not limited to, the field of rail transit, especially a rail vibration damping fastener. Background technique [0002] In recent years, with the rapid development of rail transit systems represented by subways and intercity railways, it has effectively alleviated the tension of urban traffic. At the same time, the vibration and noise pollution caused by these transportation methods have also brought people Production and life have brought great troubles. As a connecting part between the rail and the sleeper, rail fasteners not only have the function of fixing the rail, but also their vibration and noise reduction functions have attracted more and more attention. [0003] At present, a series of rail fastener products with vibration and noise reduction functions have been launched on the market. Among many damping fastener products, a damping fastener that clamps and lifts the rail from both sides of the rail has a high da...
