Problems solved by technology

[0003] like figure 1 and figure 2 As shown, the current rail telescopic regulator 100' mainly adopts a structure in which the basic rail 104' is telescopic and the tip rail 106' is fixed. The basic rail brace 170' and the platform 132' buckle the basic rail 104'. In the state of the telescopic adjuster 100', the basic rail support 170' and the platen 132' must be able to effectively withhold the basic rail 104'. A certain gap should be reserved between the rail support 170' and the basic rail waist 156', and between the platform 132' and the base rail 104'. , easy to turn outward, making the overall structure of the rail telescopic adjuster 100' unstable

Abstract

The invention provides a steel rail telescopic regulator. The steel rail telescopic regulator comprises: a base plate, wherein the base plate comprises a bottom plate and a first table plate, and theupper surface of the bottom plate is obliquely arranged; a stock rail fixed on the bottom plate, wherein at least part of the areas of a plurality of cross sections, perpendicular to the length direction of the stock rail, of the stock rail are unequal; a switch rail arranged on the first table plate, wherein at least part of the switch rail is located on the outer side of the stock rail, the areas of multiple cross sections, perpendicular to the length direction of the switch rail, of at least part of the switch rail are unequal, and the switch rail can telescopically move in the direction perpendicular to the length direction of the switch rail; and a telescopic assembly arranged on the first table plate, wherein the telescopic assembly is configured to be suitable for stretching out anddrawing back of the switch rail and enable at least part of the switch rail head to abut against the stock rail head. According to the steel rail telescopic regulator, the problems that an existing steel rail telescopic regulator is unstable in overall structure, and the stock rail is prone to turning outwards are solved, the assembling, maintaining and repairing difficulty is lowered, and the steel rail telescopic regulator is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of rail telescopic adjustment, in particular to a rail telescopic adjuster. Background technique [0002] The rail telescopic adjuster is one of the important track components of the railway. When laying seamless lines on long continuous beams of railways, it is usually necessary to set up rail telescopic adjusters. The function of the rail telescopic regulator is not only to allow the train to pass safely and smoothly at high speed, but also to coordinate the displacement difference between the telescopic displacement of the bridge end of the long bridge and the telescopic displacement of the long rail caused by temperature, so that the temperature of the long rail on the bridge can be automatically adjusted Force, thereby reducing the load on the track and bridge. [0003] Such as figure 1 and figure 2 As shown, the current rail telescopic regulator 100' mainly adopts a structure in which the basic ra...
