Description

Technical Field

[0001] This utility model relates to the field of railway fastener technology, and in particular to a railway fastener device. Background Technology

[0002] Rail fasteners are crucial fasteners between rails and sleepers, their core functions being to fix the rail position, transfer loads, and ensure track stability. Traditional rail fasteners mainly consist of a base plate, a gauge plate, and a spring clip. During installation, the base plate is first placed on the sleeper, then the gauge plate is placed on one side of the base plate to control the rail spacing. Finally, one side of the spring clip is embedded in a groove and tightened with bolts; the other side of the spring clip is used to secure the bottom of the rail. The installation process is cumbersome, requiring adjustments to the alignment of the base plate, gauge plate, and spring clip. In railway construction, one kilometer of railway requires 1600 to 1680 sleepers, and each sleeper requires four sets of rail fasteners. Therefore, one kilometer of railway requires 6400 to 6720 sets of rail fasteners, representing a massive undertaking. The traditional installation method for rail fasteners is both time-consuming and labor-intensive. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model proposes a rail fastening device, which aims to solve the problem of cumbersome installation steps of traditional rail fasteners and reduce the workload when installing rail fasteners.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rail fastening device, comprising a rail fastener, the rail fastener including a gauge baffle, a baffle seat, and an elastic bar. The baffle seat is provided with a limiting groove that cooperates with the gauge baffle. The gauge baffle is provided with an arc-shaped groove that cooperates with the elastic bar. A baffle buckle is provided on one side of the middle of the limiting groove, and an arc-shaped elastic bar limiting buckle is provided on the other side of the limiting groove. The arc-shaped elastic bar limiting buckles are symmetrically arranged on both sides of the baffle buckle. A through groove is provided in the middle of the gauge baffle. When the gauge baffle cooperates with the baffle seat, the baffle buckle passes through the through groove to limit the gauge baffle in the horizontal and vertical directions. When the elastic bar cooperates with the gauge baffle, the arc-shaped elastic bar limiting buckle locks one side of the elastic bar to limit the elastic bar.

[0005] Furthermore, the upper part of the baffle buckle is provided with a sloping surface, and the lower part near the limiting groove is provided with a square slot.

[0006] Based on the above, after the gauge baffle is installed onto the baffle seat, part of the gauge baffle structure will be inserted into the square slot, which limits the gauge baffle.

[0007] Furthermore, baffle limit blocks are provided at both ends of the limiting groove.

[0008] Based on the above, during the transportation of the gauge baffle, the gauge baffle will experience significant shaking. The baffle limiting block and the baffle buckle together limit the gauge baffle in the horizontal direction to prevent the baffle buckle from being damaged by large impact forces.

[0009] Furthermore, a locking part is provided on the side of the gauge baffle away from the arc groove, which is used to limit the movement of the rail.

[0010] Furthermore, the baffle seat, baffle buckle, and arc-shaped elastic strip limit buckle are integrally injection molded glass fiber reinforced polyamide board.

[0011] Furthermore, the spring bar is coated with an insulating material.

[0012] Furthermore, the rail fastening device also includes a locking device for locking the rail fastener. The locking device includes a locking bolt, an anti-loosening washer, and an anti-loosening washer. When locking the rail fastener, the locking bolt passes through the through groove of the anti-loosening washer, the anti-loosening washer, the elastic strip, and the gauge baffle in sequence, and engages with the sleeper through a thread.

[0013] Furthermore, the elastic bar includes an elastic bar limiting area, a pressing area, and a bolt locking area. The arc-shaped elastic bar limiting buckle cooperates with the elastic bar limiting area to limit the elastic bar in the horizontal and vertical directions. The locking device locks with the bolt locking area, so that the pressing area applies a downward pressing force to the locking part of the gauge baffle.

[0014] In summary, this utility model, by setting baffle buckles and arc-shaped elastic clips on the baffle seat, can pre-assemble the gauge baffle, baffle seat, and elastic clip into a structurally stable assembly. When the rail fastener needs to be installed on the sleeper, simply place the pre-assembled rail fastener on the sleeper and secure it with the locking device. Compared with traditional installation methods, the rail fastener installation operation of this utility model is more convenient and faster. Moreover, the railway construction environment is relatively harsh; being able to assemble the rail fastener in advance and transport it to the destination not only reduces the workload of workers but also speeds up railway construction time.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0022] like Figures 1 to 5 As shown, a rail fastening device includes a rail fastener, which comprises a gauge baffle 1, a baffle seat 2, and an elastic strip 3. The baffle seat 2 is provided with a limiting groove 21 that cooperates with the gauge baffle 1. The gauge baffle 1 is provided with an arc-shaped groove 11 that cooperates with the elastic strip 3. A locking part 13 is provided on the side of the gauge baffle 1 away from the arc-shaped groove 11, which is used to limit the rail movement. A baffle latch 23 is provided on one side of the middle of the limiting groove 21. The upper part of the baffle latch 23 is provided with a slope surface 231, and the lower part near the limiting groove 21 is provided with a square locking groove 232. After the gauge baffle 1 is installed onto the baffle seat 2, part of the structure of the gauge baffle 1 will be inserted into the square slot 232, which limits the gauge baffle 1. An arc-shaped elastic retaining buckle 24 is provided on the other side of the retaining groove 21, and the arc-shaped elastic retaining buckle 24 is symmetrically arranged on both sides of the baffle buckle 23. A through groove 12 is provided in the middle of the gauge baffle 1. When the gauge baffle 1 and the baffle seat 2 are engaged, the baffle buckle 23 passes through the through groove 12 to limit the gauge baffle 1 in the horizontal and vertical directions. When the elastic bar 3 is engaged with the gauge baffle 1, the arc-shaped elastic retaining buckle 24 locks one side of the elastic bar 3 and limits the elastic bar 3.

[0023] The two ends of the limiting groove 21 are provided with baffle limiting blocks 26. During the transportation of the gauge baffle 1, the gauge baffle 1 will shake significantly. The baffle limiting blocks 26 and the baffle buckles 23 together limit the gauge baffle 1 in the horizontal direction to prevent the baffle buckles 23 from being damaged by large impact forces.

[0024] The baffle seat 2, baffle buckle 23, and arc-shaped elastic retaining buckle 24 are integrally injection molded glass fiber reinforced polyamide sheets. The glass fiber reinforced polyamide sheets have a certain degree of elasticity and toughness. Combined with the sloping surface 231 on the baffle buckle 23 and the arc structure of the arc-shaped elastic retaining buckle 24, the gauge baffle 1 and elastic strip 3 can be smoothly installed onto the baffle seat 2 by extrusion.

[0025] like Figure 2 As shown, the rail fastening device also includes a locking device for locking the rail fastener. The locking device includes a locking bolt 4, an anti-loosening washer 41, and an anti-loosening washer 42. When locking the rail fastener, the locking bolt 4 passes through the anti-loosening washer 42, the anti-loosening washer 41, the elastic strip 3, and the through groove 12 of the gauge baffle 1 in sequence, and is threadedly engaged with the sleeper.

[0026] like Figure 1 and Figure 5 As shown, the elastic bar 3 includes an elastic bar limiting area 31, a pressing area 32, and a bolt locking area 33. The arc-shaped elastic bar limiting buckle 24, by cooperating with the elastic bar limiting area 31, limits the elastic bar 3 in both the horizontal and vertical directions. The elastic bar 3 can also rotate under the restriction of the arc-shaped elastic bar limiting buckle 24. The locking device, by locking with the bolt locking area 33, causes the pressing area 32 to apply a downward pressing force to the locking part 13 of the gauge baffle 1, thereby limiting the gauge baffle 1 to the rail. In addition, the elastic bar 3 is coated with an insulating material made of polyvinyl chloride.

[0027] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
