Abstract

The invention discloses a subway track supporting sleeper with a safety warning function, which comprises a sleeper body, track mounting grooves, tracks, mounting columns, L-shaped fixing pieces, mounting screw holes and warning pigment outlets, the track mounting grooves are formed in the two sides of the top of the sleeper body, and reserved mounting holes are formed in the track mounting grooves; fixing screw holes are formed in the two sides of the track mounting grooves, mounting columns matched with the reserved mounting holes are mounted at the bottoms of the tracks, L-shaped fixing pieces are mounted in the two sides of the tracks, mounting screw holes are formed in the outer sides of the bottoms of the L-shaped fixing pieces, the tracks are mounted in the track mounting grooves in the two sides respectively, and the mounting columns are mounted in the reserved mounting holes. The mounting screw holes in the L-shaped fixing pieces on the two sides are connected into the fixing screw holes through bolts, and a warning pigment outlet is formed in the center of the top of the sleeper body. Through the internal unique structure, the sleeper having problems in use can be quickly found in cooperation with the warning pigment, timely replacement is facilitated, and safety accidents are prevented.

Description

technical field [0001] The invention relates to a subway rail support sleeper with a safety warning function, belonging to the technical field of subway rails. Background technique [0002] Concrete sleepers have a long service life, high stability, less maintenance workload, and much lower damage and scrap rates than wooden sleepers. On seamless lines, the stability of reinforced concrete sleepers is 15-20% higher than that of wooden sleepers on average, so it is especially suitable for high-speed passenger lines. However, the loss of the sleeper is large in places where the roadbed is unstable and in winter. and difficult to detect in time. Contents of the invention [0003] The object of the present invention is to provide a subway rail support sleeper with a safety warning function, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: ...
