Track plate structure for climbing and manufacturing method of track plate structure

Abstract

The invention relates to a track plate structure for climbing and a manufacturing method of the track plate structure, and belongs to the technical field of tracks. The track plate structure comprisesa plate body, wherein longitudinal post-tensioned prestressed hole channels are reserved in the plate body, and the longitudinal post-tensioned prestressed hole channels have camber; rail bearing grooves which are concavely formed and are used for installing steel rails in an embedded mode are formed in the top surface of the plate body, the rail bearing grooves longitudinally penetrate through the two end surfaces of the plate body, and the two rail bearing grooves are arranged at intervals in parallel; and two rubber wheel friction structural surfaces with a certain width are arranged on the top surface of the plate body, the rubber wheel friction structural surfaces are parallel to the rail bearing grooves, and the rail bearing grooves are positioned between the two rubber wheel friction structural surfaces. According to the track plate structure, the track function and the bridge function are combined into one, so that the structure is simple, the construction cost can be reduced,and the track plate structure is another brand-new upper structure of a bridge; and rubber wheel friction structural surface rail vehicles are equipped with steel wheels and rubber wheels, and the rubber wheels and the rubber wheel friction structural surfaces are in contact and fit, so that the rail vehicles can solve the problem of insufficient adhesion force, and the rail vehicles can be pulled onto a larger slope (4%-18%).

Description

technical field [0001] The invention relates to the technical field of track and bridge engineering, in particular to a track plate structure for climbing and a manufacturing method. Background technique [0002] A railway bridge is a structure built for railways to cross rivers, lakes, straits, valleys or other obstacles, and to realize the three-dimensional intersection of railway lines and railway lines or roads. The most widely used railway bridge is the girder bridge. It is the most widely used bridge type and can be subdivided into simply supported girder bridges, continuous girder bridges and cantilever girder bridges. [0003] The plate girder is the superstructure of the bridge. After the bridge is built, due to the action of loads such as locomotives, there will be a downward displacement, which is also called deflection; this will cause the actual elevation of the bridge deck to be inconsistent with the design elevation. In order to eliminate or reduce the degr...

Problems solved by technology

[0004] Moreover, in existing railway bridges, the track slab is a track slab, and the bridge is a bridge, the structure is complex, and the construction cost is high

[0005] In addition, the existing slab ballastless track uses multiple fastening systems arranged at intervals to fix the rail. These fastener systems provide intermittent support points for the rail, which is the main reason for the vibration source of the railway track and the short-wave irregularity of the rail surface. reason

The short-wave irregularities cause serious wear to the rails and wheels. If things go on like this, the wheels will be damaged into polygons. Therefore, the rails and wheels need to be polished regularly, otherwise it will greatly affect the safety, comfort and instability of locomotive operation; Will shorten the life of rails and wheels
