Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] Such as figure 1 As shown, the railway track system includes a track slab 1, a plurality of sleepers 2 laid on the track slab 1 and two rails 3 laid on the sleepers 2, with the extension direction of the track as the longitudinal direction, in a plane parallel to the track surface The direction perpendicular to the longitudinal direction is the transverse direction. Specifically, the sleepers 2 are horizontally arranged and provided with a plurality of slee...

Abstract

The invention discloses an anti-climbing device for a railway track system. The extending direction of the trackis used as the longitudinal direction; the direction perpendicular to the longitudinal direction in a plane parallel to the track surface is a transverse direction, the anti-climbing device comprises at least one pair of anti-climbing devices which are transversely and symmetrically arranged; the anti-climbing device comprises an anti-climbing base and a force transmission pad. The anti-climbing base is arranged at the bottom of the steel rail and located between two adjacent sleepers. The end faces of the two longitudinal sides of the anti-climbing base abut against the longitudinal end faces of the two adjacent sleepers in an attached mode respectively, the force transmission pads are connected to the upper end of the anti-climbing base, and the force transmission pads are symmetrically attached to the side faces of the two sides and the bottom of the steel rail. By the adoption of the device, the problems that an existing railway track anti-climbing device is poor in anti-climbing effect and short in service life can be solved.

Description

technical field [0001] The invention belongs to the technical field of railway tracks, and more specifically relates to an anti-climbing device for railway track systems. Background technique [0002] When the rail is deflected by the dynamic load of the locomotive, the rail section rotates, the top of the rail is shortened, and the bottom of the rail is elongated. If the rail and the sleeper are not firmly connected, the rail will be deflected when subjected to the axle load of the vehicle, and the rotation of the rail section in front of the wheel will cause the bottom of the rail to slide on the backing plate along the direction of travel, resulting in crawling. Crawling is one of the important reasons for the damage of the track. It can cause the position of the sleeper to be skewed, the spacing is not correct, and the track gap is uneven, which is very destructive to the line. Rail crawling not only drives joint ties to produce joint diseases, but also the displacement...
