Description

Technical Field

[0001] This utility model relates to the field of fastener protection equipment technology, specifically a protective structure for a subway track laying fastener system. Background Technology

[0002] Subways are a widely used form of rail transit, playing a vital role in transportation in many cities. During the design and operation of subway systems, the vibration and noise generated cannot be ignored and must meet national environmental noise and vibration standards. This places higher demands on the work of designers and researchers. Currently, track vibration reduction measures for urban rail transit projects mainly fall into three categories: fastener vibration reduction, sleeper vibration reduction, and track bed vibration reduction.

[0003] Chinese Utility Model Patent (Announcement No.: CN206279757U) discloses an openable cross-type coupler protective sleeve for safety protection on a scaffolding cross-hinged coupler. It is integrally injection molded from two outwardly protruding structures, a left cover and a right cover. The protective sleeve is integrally injection molded through a central transition connecting rib. The left cover has two integrally injection molded upper and lower straps, and the right cover has two integrally injection molded upper and lower buckles. The left cover has an inner edge, and the right cover has an outer edge. The left and right covers have symmetrical steel pipe locking slots that engage with the steel pipes on both sides. When the left and right covers are joined and folded together, they are pressed and fastened together by the upper and lower straps and buckles.

[0004] The fastener protection sleeves in the above cases are only applicable to traditional pipe fasteners on construction sites, and not to fastener systems on subway tracks. Moreover, the above-mentioned fastener protection sleeves can only protect individual fasteners, and cannot protect the entire fastener system, so the protection scope is not comprehensive. Therefore, we propose a subway track laying fastener system protection structure to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a protective structure for a subway track laying fastener system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective structure for a subway track laying fastener system includes a buffer pad, wherein insertion holes are provided at the four corners of the buffer pad.

[0008] A trapezoidal limiting boss is movably installed on the middle part of the buffer pad. A protective structure is movably installed on the buffer pad, and parallel circular connecting grooves are opened on both ends of the protective structure. Fastening bolts are movably installed in the connecting grooves, and the fastening bolts pass through the connecting grooves to the insertion holes.

[0009] Parallel elastic connecting strips are movably installed on both sides of the protective structure.

[0010] Parallel rectangular mounting slots are provided on both sides of the protective structure. The elastic connecting strip passes through the mounting slot on one side to the mounting slot on the other side. The two ends of the elastic connecting strip are fixed with fixing strips, and the sidewalls of the fixing strips are movably connected to the inner wall of the mounting slot.

[0011] The upper elastic connecting strip is shorter than the lower elastic connecting strip, and the length and width of the fixing strip are the same as the length and width of the mounting groove. An arc-shaped transparent plate is provided on the protective structure between the ends of the elastic connecting strip.

[0012] The protective structure includes a heat-shrinkable layer, and an anti-aging layer is fixedly provided below the heat-shrinkable layer. A vulcanized layer is fixedly provided below the anti-aging layer, and a shaping gel is fixedly provided at the bottom of the vulcanized layer. A flexible plate is fixedly provided below the shaping gel.

[0013] The heat-shrinkable layer, anti-aging layer, vulcanization layer, and shaping gel are symmetrically arranged on the upper and lower flexible surfaces in sequence.

[0014] The protective structure is shaped like a "Z", and the elastic connecting strip also has heat-shrink properties.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Install the protective structure by fastening bolts through the circular connecting grooves of the protective structure into the insertion holes on the buffer pad plate. During installation, the arc-shaped transparent plate should face upwards to facilitate observation of the installation of the internal structure of the fastening system. The addition of elastic connecting strips allows for elastic connection of the sides of the protective structure, further protecting the fastening system.

[0017] The protective structure is composed of a heat-shrinkable layer, an anti-aging layer, a vulcanized layer, a shaping gel, and a flexible sheet. The addition of the heat-shrinkable layer allows the protective structure to deform under heat and adhere to the surface of the fastener system, making the protection more complete. The anti-aging layer can effectively enhance the service life of the protective structure. The protective structure with the vulcanized layer has strong rigidity, making the protective structure less susceptible to damage. The shaping gel further strengthens the protective structure while allowing it to be folded at will for easy storage. The flexible sheet is among the layers and provides support for the protective structure. The addition of each layer of materials gives the protective structure a stronger protective performance.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 The subway track-laying fastening system protective structure includes a buffer pad 1, with insertion holes 11 at its four corners. A trapezoidal limiting boss 3 is movably installed on the center of the buffer pad 1. A protective structure 4 is movably installed on the buffer pad 1, with parallel circular connecting grooves 41 at both ends of the protective structure 4. Fastening bolts 2 are movably installed in the connecting grooves 41, extending through the connecting grooves 41 to the insertion holes 11. Parallel elastic connecting strips 5 are movably installed on both sides of the protective structure 4.

[0025] Parallel rectangular mounting grooves 43 are opened on both sides of the protective structure 4. The elastic connecting strip 5 passes through the mounting groove 43 on one side to the mounting groove 43 on the other side. The two ends of the elastic connecting strip 5 are fixedly connected to the fixing strip 51, and the side wall of the fixing strip 51 is movably connected to the inner wall of the mounting groove 43.

[0026] The upper elastic connecting strip 5 is shorter than the lower elastic connecting strip 5. The length and width of the fixing strip 51 are the same as the length and width of the mounting groove 43. An arc-shaped transparent plate 42 is provided on the protective structure 4 between the ends of the elastic connecting strip 5.

[0027] The protective structure 4 includes a heat-shrinkable layer 44, and an anti-aging layer 48 is fixedly disposed below the heat-shrinkable layer 44. A vulcanized layer 45 is fixedly disposed below the anti-aging layer 48, and a shaping gel 47 is fixedly disposed at the bottom of the vulcanized layer 45. A flexible plate 46 is fixedly disposed below the shaping gel 47.
