Plate pressing device

Abstract

The invention discloses a plate pressing device and relates to a device for pressing track plates during ballastless track construction. The device is mainly designed to solve the problems that prior track plate fine adjustment devices are complicated in structure, high in production cost and the like. The device comprises an angle steel and a plate pressing bolt, and a longitudinal channel steel is perpendicularly erected in the middle of the angle steel and welded and fixed with a horizontal setting edge and a vertical edge of the angle steel. An expansion bolt anchorage hole is formed in the middle of the horizontal setting edge of the angle steel, and a template reinforcing bolt is added on each of the two sides of the angle steel vertical edge. A horizontally arranged transverse channel steel is welded on each of the two sides of the upper portion of the longitudinal channel steel, and triangular steel plates are added between the transverse channel steels and the longitudinal channel steel for fixing. A nut of the plate pressing bolt is welded and fixed on the two transverse channel steels. A compression bolt can be added, a threaded rod of the compression bolt is disposed between the two transverse channel steels, a nut is disposed above the two transverse channel steels, a spacer is arranged under the nut to be supported on the two transverse channel steels, and a nut is arranged at the lower end of the threaded rod of the compression bolt. The device has the advantages of being simple in structure and low in cost.

Description

Technical field: [0001] The invention relates to a device for pressing the track slab to prevent it from floating when concrete is poured between the track slab and the base concrete during ballastless track construction. Background technique: [0002] During the construction of ballastless track, concrete should be poured between the track slab and the base concrete. In order to prevent the track slab from being forced to float up when the concrete is poured, all construction units currently use the track slab fine adjuster to fix the track slab. , three track plate fine adjusters are installed at both ends of each track plate (on both sides of the track), and each track plate must have six track plate fine adjusters for fixing. The structure is relatively complicated, each price is about 800 yuan, and the weight is about 25 kilograms. A large number of uses not only increases the production cost, but also requires a lot of labor for disassembly and transportation, and the ...
