Fixed connection component of seamless toothed rail on long and large slope line bridge

Abstract

The invention relates to a fixed connection component of a seamless toothed rail on a long and large slope line bridge. The fixed connection component comprises L-shaped connectors which are arrangedon the upper side of a sleeper and on the two transverse sides of the toothed rail in left-right symmetry. Each L-shaped connector comprises a bottom plate and a side plate. A round hole or long roundhole is formed in each bottom plate, and the bottom plate is fixed to the top face of the sleeper through an anchoring bolt. A round hole or long round hole is formed in each side plate, and the sideplate is fixed to the side face of the sleeper through a long bolt. When the toothed rail is located on the bridge, the bridge has telescopic deformation under the influences of the air temperature,and therefore a rack is driven to have displacement; the width of tooth grooves at a beam seam changes, so a gear cannot be effectively meshed with the toothed rail, and the normal driving of a locomotive is affected; by means of the technology, when displacement happens between the rack at the beam seam and a beam body, the width of the tooth grooves can keep unchanged, and the driving continuityof the locomotive is ensured.

Description

technical field [0001] The invention belongs to the field of rail engineering, and in particular relates to a seamless cog rail fixed coupling structure on a bridge with a long ramp. Background technique [0002] The cog railway is a railway system designed to overcome the lack of adhesion of ordinary wheel-rail railways on long slopes. One or more special cogs are added in the middle of the track. The locomotive is equipped with one or more gears, which mesh with the rack rails when running to provide power. It has the characteristics of strong climbing ability (slope up to 48%), large traction force, heavy load, and can reduce the length of the stretching line. It mainly serves the railways in mountainous areas and mining areas. [0003] At present, this technology has been applied in foreign countries. The more famous routes include the Jungfraujoch in Switzerland, Pilatus in Switzerland, Washington DC in the United States, and the Zugspitze in Germany. The existing cog...

Problems solved by technology

The existing cog railways in China are basically distributed in mining areas, and most of them are laid underground, and there is no case of laying on bridges
