Urban rail wheel guard rail device and its installation method

Abstract

The invention provides a novel urban railway guard rail device which comprises a guard rail support. The guard rail support is in an L shape, one end of the guard rail support is located below a traveling rail and connected with the rail bottom of the traveling rail in a fastened mode, the other end of the guard rail support is connected with a guard rail, the end portion of the guard rail support is sleeved with a gumshoe type elastic cushion block, the guard rail is located above the gumshoe type elastic cushion block, and the top of the guard rail is higher than the top of the traveling rail. The novel urban railway guard rail device is simple in structure, safe and reliable in use and convenient to disassemble and assemble, guarantees are provided for safety traveling of an urban railway transport vehicle, abrasions on the lateral side of the rail head of a curve outer steel rail are reduced, the service life of the steel rail is prolonged, the capacity of a rail frame structure for resisting the traverse deformation is improved, the working loads for maintaining the small-radius curved section rail are reduced, and the operating cost is reduced.

Description

Technical field [0001] The invention relates to a transportation facility, in particular to a novel wheel guard rail device for urban rail transit and an installation method thereof. Background technique [0002] Urban rail transit has a large volume, dense traffic, and fast speed. Due to the limitation of urban terrain, there are not only many elevated rail line sections, but also a large number of curved rail lines. In particular, small radius curved rails are the weak link of rail lines, and trains are derailed. Accidents often occur here. At the same time, the maintenance of urban rail transit track lines is extremely inconvenient, especially the track frame structure of the small radius curve track section has weak resistance to lateral deformation, which causes most of the track maintenance workload to concentrate on this, and the small radius curve track rail side wears serious and shortens The service life of the rail is increased. [0003] Among the existing wheel guard ...

AI Technical Summary

Problems solved by technology

At the same time, the maintenance of urban rail transit track lines is extremely inconvenient, especially the track frame structure of the small-radius curved track section has a weak ability to resist lateral deformation, resulting in most of the track maintenance workload being concentrated here, and the side of the small-radius curved track is severely worn and shortened. rail service life

[0003] Among the existing guard rail devices, there is no guard rail device specially suitable for urban rail transit track lines to prevent train wheel derailment, slow down the wear of the rail side and strengthen the track frame structure
