Abstract

The invention provides a rail fastener system for solving the problems existing in current systems that the system safety is low, the system maintenance difficulty is big and the system maintenance cost is high. The bottom of a steel rail is placed on a sleeper through a pad plate under the rail, and two fastening assemblies are symmetrically and respectively arranged on the two transverse sides of the steel rail; each fastening assembly comprises a gauge baffle, a W-shaped elastic strip, a screw spike and a casing, each casing is embedded in the sleeper, one transverse side of each gauge baffle abuts against the steel rail, the other side of each gauge baffle abuts against a baffle shoulder of the sleeper, the W-shaped elastic strips are pressed on the gauge baffles and the steel rail, and each screw spike is in threaded connection with the corresponding casing after sequentially penetrating through the corresponding elastic strip and gauge baffle; an arc groove extending in the length direction of the steel rail is formed in the side, close to the baffle shoulder of the sleeper, of each gauge baffle; two symmetrical arc-surface grooves are formed in the side, close to the steel rail, of each gauge baffle, and a convex part is arranged in the middle of each arc groove; the tails of the W-shaped elastic strips are fitted with the arc grooves, the two sides of the middles of the W-shaped elastic strips are fitted with the arc-face grooves respectively, and the convex parts vertically limit the two sides of the tail of each W-shaped elastic strip.

Description

technical field [0001] The invention relates to the field of railway fasteners, in particular to a rail fastener system. Background technique [0002] Rail fasteners are an important part of the track structure. They are used to fix the position of the rail, prevent the longitudinal and lateral displacement of the rail, and prevent the rail from tipping over. At the same time, it can also provide the necessary rail elasticity and transmit the force on the rail to the foundation under the rail. . The existing rail fastening system includes an under-rail backing plate placed at the bottom of the rail and fastening components symmetrically arranged on both sides of the rail. The fastening components include gauge baffles, elastic strips, spiral spikes and sleeves It is pre-buried in the sleeper, wherein the gauge baffle is placed on the sleeper and one side of it is against the rail and the other side is against the shoulder of the sleeper, so that the rail is fastened to the ...
