Description

Track slab for damping urban rail Technical Field The utility model relates to the field of machinery, in particular to rail transit equipment, and particularly relates to a rail plate for damping urban rail. Background The track slab refers to an under-rail member, which is a slab in the form of a structural form, for supporting and fixing rails, and distributing loads transmitted from a train through the rails to an under-slab base. The track boards are paved on the substrate of the track bed, the upper surface of the substrate is further paved with a concrete adjusting layer, the track boards are paved on the upper surface of the concrete adjusting layer, every two track boards are connected end to end, and the tracks are installed on the track bearing platform of the track boards through bolts. In the prior art, the upper surface of track board is planar structure, when using, ponding easily, leads to track board life to reduce to track board two liang looks back, mainly through installing the track connection at the rail bearing bench between two adjacent track boards, connection stability between the track board is not good. Accordingly, there is a need for an improved technique for solving the above-mentioned problems of the prior art. Disclosure of utility model The utility model aims to provide a track slab for damping urban railway, which solves the problems in the prior art. The track plate for urban rail vibration reduction comprises a plate body, wherein limit grooves are formed in two ends of the plate body, positioning protruding blocks are arranged at one end of the plate body and located on two sides of the limit grooves, positioning grooves are formed in the other end of the plate body and located on two sides of the limit grooves, the positions of the positioning protruding blocks and the positions of the positioning grooves are matched with each other, the height of the upper surface of the plate body is gradually reduced from the middle position to two sides, V-shaped drainage grooves are symmetrically formed in the upper surface of the plate body and located on two sides of the upper surface of the plate body, drainage grooves are formed in the middle position of the upper surface of the plate body and located on the V-shaped drainage grooves, the distance from the V-shaped drainage grooves to adjacent sides of the plate body is gradually increased from the middle position of the V-shaped drainage grooves to two ends, and two rows of rail bearing tables are symmetrically arranged on two sides of the upper surface of the plate body. Preferably, the utility model provides a track slab for damping urban rail, wherein a plurality of hoisting embedded sleeves are arranged on two sides of a slab body. Preferably, the rail plate for urban rail vibration reduction provided by the utility model is characterized in that the four corners of the plate body are provided with stray current terminals, and the stray current terminals are all positioned at the outer sides of the corresponding V-shaped drainage grooves. Preferably, the utility model provides a track slab for damping urban rail, wherein each track supporting platform is embedded with a fastener sleeve. Preferably, the track plate for urban rail vibration reduction provided by the utility model is characterized in that both sides of the outer end of the positioning lug are provided with circular arc-shaped chamfers, and the width of the positioning lug is matched with the width of the positioning groove. Preferably, the utility model provides a track slab for damping urban rail, wherein a damping pad is attached to the lower surface of the slab body. Compared with the prior art, the utility model has the beneficial effects that: (1) The two ends of the plate body are respectively provided with the positioning convex blocks and the positioning grooves, during construction, the joint of every two plate bodies is provided with the limiting grooves to be matched with the positioning convex blocks of the concrete adjusting layer, so that the connection stability between the track plates and the concrete adjusting layer is greatly improved, and on the other hand, the two plate bodies are matched with the positioning convex blocks in a plugging manner through the positioning grooves, so that the connection stability between the two adjacent track plates is greatly improved. (2) The height of plate body upper surface reduces gradually to both sides from the intermediate position, and V type water drainage tank and water drainage notch are reserved to the both sides of plate body upper surface, and the plate body upper surface of being convenient for on the one hand can not ponding to guarantee the life of track board, on the other hand is convenient for concentrate the drainage to both sides through V type water drainage tank and water drainage notch.
