Rapid fixing device for railway

Abstract

The invention discloses a rapid fixing device for a railway. The rapid fixing device comprises a rail, wherein the left side and the right side of the bottom of the rail are fixed on a sleeper throughrail fixing pieces, an annular fixing device is arranged on the upper surface of the rail, fixing blocks I are fixedly connected to the left side and the right side of the annular fixing device, a hole I is formed in the each fixing block I, a fixing bolt I is in threaded connection in the each hole, and the bottom of the each fixing bolt I abuts against the upper surface of the rail. According to the device, the fixing bolt I and two fixing bolts II are arranged on the outer surface of the rail, meanwhile, the fixing block I is arranged on the fixing bolt I, the fixing block II is arranged on the fixing bolt II, through cooperation of the fixing blocks and the fixing bolts on the two sides of the annular fixing device, the rail which waits to replace and to be installed can be rapidly and accurately fixed at the fixing position of an original damaged rail, so that the working efficiency is greatly improved, the labor cost is reduced, and the working quality is guaranteed.

Description

Technical field [0001] The invention relates to the field of auxiliary devices for traffic and roads, in particular to a fast fixing device for railways. Background technique [0002] Existing trains, high-speed railways, subways and other trains all need rails when they are running. The cross-section of the rails is generally I-shaped. Both sides of the rail are fixed to the sleepers by rail fixings. The rail fixings generally include gauge blocks, pressure plates, and elastic. Strips, washers, nuts. One side of the pressure plate is fixed on the sleeper by a nut and screw mechanism; the other side is provided with a clamping edge to fix the rail; a spring strip and a washer are arranged between the pressure plate and the nut; and one side of the pressure plate is fixed to the sleeper and a gauge block is also provided. The traditional method for fixing rail fixings is to manually place the gauge block on the bottom of the sleeper after determining the position of the rail, and...

Problems solved by technology

Due to the many steps in the assembly process and manual placement, the position of each part needs to be adjusted during placement. The speed of manual construction is slow, and the position of each part is prone to shift, which affects the degree of rail fixation.

In addition, due to the large difference in the shape of the rail fixing parts, separate processing, packaging and transportation are generally used, resulting in time-consuming and labor-intensive assembly and transportation of workers, which will reduce the construction speed and consume a lot of manpower, which is not conducive to the construction efficiency of the rail.
