Embodiment 1

[0023] Embodiment one: if Figure 1 to Figure 4 As shown, the self-protective rail fastener is symmetrically arranged on both sides of the rail 2, that is, this embodiment is used in pairs; it includes a spiral spike 3 fixedly installed on the sleeper 1, and the spiral spike 3 is located on the A gauge baffle 4 is installed above the sleeper 1, and a baffle seat 5 is installed between the gauge baffle 4 and the sleeper 1; Elastic bar 6, described rail gauge baffle plate 4 is provided with the elastic bar arc groove corresponding to described elastic bar 6, and described elastic bar arc groove is well known to those skilled in the art, no longer Repeat; the spiral spike 3 is located above the elastic strip 6 and is provided with an elastic strip fastening device 7, and the gauge baffle 4 adopts an oblong hole gauge baffle of the elastic strip I-type fastener. The bar 6 adopts the A-type elastic strip of the elastic strip I-type fastener, the said baffle seat 5 adopts the baffl...

Embodiment 2

[0029] Embodiment two: if Figure 5 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that: the side guard connecting plate 42 is arranged parallel to the dust-proof surface 81, and the dust-proof surface 81 is provided with a countersunk hole 85 , the side guard connecting plate 42 is provided with a fixing screw hole corresponding to the countersunk hole 85; in this embodiment, the dust cover 8 can be further fixed by using the hexagon socket countersunk head bolt, on the one hand, it can prevent the The loosening of the above-mentioned dust cover 8 can, on the other hand, prevent irrelevant personnel from tampering or even stealing. Of course, the countersunk bolts can also be specially made in the form of an inner triangle, which is well known to those skilled in the art and will not be repeated here.

Abstract

The invention discloses a self-protection track buckle which is symmetrically arranged on two sides of a steel rail and comprises spiral rail nails, wherein gauge apron plates, elastic strips and elastic strip fastening devices are sequentially mounted on the spiral rail nails; two side protection plates and side protection connecting plates are arranged on the gauge apron plates; a dustproof cover plate is mounted between the two side protection plates; the dustproof cover plate, the two side protection plates, the gauge apron plates and the steel rail form a protection space together. On premise that buckle pressure is ensured, the two side protection plates are tightly adhered to a rail waist, so that the situation that a buckle is loosened or inclined because of mechanical collision force is effectively avoided; the dustproof cover plate and the side protection plates form a protection cover of a protection station bolt, so that when cargoes are loaded and unloaded, multiple route equipment damages caused by direct collision of machines such as excavators and forklifts to exposed station bolts are effectively avoided, in addition, problems such as rusting of buckles buried by bulk cargos are solved, and the maintenance workload and the maintenance cost of routes are greatly reduced. In addition, the self-protection track buckle is low in manufacturing cost and relatively convenient to maintain, and thus the self-protection track buckle has very high social values.

Description

technical field [0001] The invention relates to the technical field of rail fastener systems, in particular to a self-protective rail fastener. Background technique [0002] Railways provide a lot of convenience for transportation and cargo transportation. The railway track is mainly fixed by track fasteners. The most commonly used track fasteners are the structural form that uses elastic strips to press the gauge baffle (such as Image 6 shown). The elastic strips, fastening nuts, spikes, etc. of this structure are directly exposed on both sides of the rail. When loading and unloading bulk cargoes such as coal, soda stone, bauxite, etc. at some stations, excavators, forklifts and other machinery are used to carry out operations. It will inevitably cause different degrees of bumps on the rails and sleepers, resulting in skewed and missing sleeper station bolts, broken clips or gauge baffles, etc. In severe cases, it may also cause empty suspension plates on the line and af...
