Steel rail telescopic adjuster fastener

Abstract

The invention provides a steel rail telescopic adjuster fastener. The steel rail telescopic adjuster fastener comprises a metal base plate, and a metal antifriction rail brace is arranged on the non-working edge of a stock rail on the upper end face of the metal base plate; the metal antifriction rail brace is in friction contact with the stock rail in a vertical buckling and attaching manner through a non-metal antifriction rail brace antifriction layer, and is fixedly connected with the metal base plate through a vertical T-shaped bolt; a metal antifriction pinch plate is arranged at the working edge of the stock rail; the metal antifriction pinch plate is is in friction contact with the stock rail in a vertical buckling and attaching manner through a non-metal antifriction pinch plate antifriction layer; the metal antifriction pinch plate is fixedly connected with the metal base plate through a vertical T-shaped bolt; a metal stopper is fixedly arranged on the upper end surface of the metal base plate; and a gap is reserved between the metal stopper and the metal antifriction rail brace, and a gauge adjusting piece made of non-metal materials is arranged in the gap. According tothe steel rail telescopic adjuster fastener, temperature stress can be transmitted through longitudinal stretching out and drawing back, and the linear smoothness of the rail is guaranteed; and in-plant assembly can be directly carried out, the product quality is controlled and accepted without relying on a reserved gap, components are simple, assembly is convenient, the assembly difficulty is greatly reduced, production is efficient, and economy and practicability are achieved.

Description

technical field [0001] The invention belongs to the technical field of fixing parts for fixing buildings, bridges and railway tracks, and in particular relates to a rail telescopic regulator fastener. Background technique [0002] The rail telescopic regulator is one of the indispensable track equipment on long-span steel girder bridges and bridges laying seamless lines. The expansion and contraction displacement of the beam end and the expansion and contraction displacement of the long steel rail, and the temperature force of the seamless line on the bridge is released, thereby reducing the longitudinal force of the seamless line on the track and the pier itself. [0003] Under the prior art, the announcement number is the disclosed rail telescopic regulator fastener of CN205046475U, the announcement number is the disclosed groove rail rail telescopic regulator of CN106337324A, the announcement number is the disclosed rail telescopic adjuster of CN102518007A, and the announ...

Problems solved by technology

The disadvantages are: it is difficult to manufacture and assemble in the factory; it has high requirements for the skills of the operators; it must be assembled and repaired one by one on site to meet the reserved clearance requirements before it can be successfully assembled, so the on-site production efficiency is not high
