Abstract

The invention relates to the field of rail transit, in particular to a combined rail bearing platform which comprises a movable supporting block used for supporting a steel rail, an inclined boss is arranged on the lower mounting surface of the movable supporting block and detachably mounted on a rail bearing base, and an inclined groove matched with the inclined boss is formed in the rail bearingbase. An anchoring part is further included, and used for fixing the movable supporting block and the rail bearing base; and anchoring holes through which the anchoring part penetrates are formed inthe movable supporting block and the rail bearing base, and the movable supporting block can be transversely adjusted through the anchoring holes. Transverse position adjustment is achieved through relative movement of the inclined boss and the inclined groove. The vertical position of the movable supporting block is adjusted by changing the thickness of the rail bearing base; in addition, by changing materials of structural components, rigidity adjustment of the rail supporting structure can be achieved, and the rail supporting structure has the effect of rail vibration reduction. All rail components are prefabricated in a factory, on-site rapid assembly is achieved, the precision is controllable, and maintenance and adjustment are convenient.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a combined rail bearing platform. Background technique [0002] With the continuous development of my country's railway construction, ballastless track has been widely used in railway construction due to its advantages of strong integrity, good smoothness, high durability, and less maintenance. The service status of the existing ballastless track shows that, especially for ballastless track in difficult and dangerous mountainous areas, such as roadbeds, tunnels, bridges and other track foundations, there is a risk of large arching or sinking deformation, which will cause the track structure on it to be damaged. With the dynamic deformation of the foundation under the line, the geometric shape of the track structure changes, which may easily cause poor ride comfort of the track line, forcing the train to slow down and pass. [0003] At present, the rail support structure of bal...
