Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway engineering technology, and in particular to a turnout sand-proof sliding plate device. Background Technology
[0002] A slide plate is a component used in railway tracks. Its main function is to reduce friction when the switch rails slide, providing smooth sliding space and ensuring smooth switch transitions. Slide plates are typically installed between the switch rails and stock rails of a turnout. By reducing friction, they allow the switch rails to slide smoothly, thus ensuring the normal operation of the turnout and the smooth operation of trains.
[0003] The existing slide plate is a one-piece structure. The long-term friction between the slide plate surface and the switch rail will cause surface wear, especially when trains pass frequently. This wear will gradually intensify, making the slide plate surface rough and uneven, affecting the normal sliding of the switch rail. Therefore, the slide plate needs to be replaced. However, the current device is not easy to disassemble during the replacement process, and the replacement rate is slow. Utility Model Content
[0004] This utility model discloses a turnout sand-proof sliding plate device, which aims to solve the technical problem that existing devices wear out after long-term use and need to be replaced, but the replacement process is inconvenient to disassemble and the replacement rate is slow.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A turnout sand-proof sliding bed device includes a sliding bed plate. The top of the sliding bed plate has two mounting holes, and each mounting hole is equipped with a fixing bolt. The top of the sliding bed plate has a rectangular groove, and the inside of the rectangular groove is equipped with an installation module. The installation module includes an installation frame, and the top of the installation frame is equipped with a protective module. The top of the installation frame is equipped with the sliding bed plate body.
[0007] By incorporating a slide bed, fixing bolts, mounting modules, a protective module, and a slide bed body, the stability of the equipment during use is improved by including the slide bed and fixing bolts; the mounting module allows for quick replacement of worn slide bed bodies, increasing the replacement rate; and the protective module prevents sand from accumulating on the surface of the slide bed body and from clogging the switch rails.
[0008] In a preferred embodiment, each of the opposite outer walls of the mounting frame is provided with a sliding groove, and each sliding groove contains a bidirectional screw rod, with one end of each bidirectional screw rod movably connected to one inner wall of the two sliding grooves; two circular holes are provided on one outer wall of the mounting frame, and rotating rods are movably connected to the inner walls of each of the two circular holes, with shaft fittings fixedly connected to one end of each of the two rotating rods, and limit grooves provided on one outer wall of each of the two shaft fittings; limit gears are fixedly connected to the outer walls of the two rotating rods, and one end of each rotating rod is fixedly connected to one end of each of the two bidirectional screw rods; the two... Each of the four bidirectional screws has two clamping plates movably connected to its outer wall. Each of the four clamping plates has a rubber pad on one side of its outer wall, and two mounting rods are fixedly connected to one side of the mounting frame's outer wall. Each of the two mounting rods has a snap-fit component movably connected to its outer wall, which snaps into two limiting gears. Each of the two mounting rods has a mounting plate fixedly connected to one end of its outer wall. Each of the two mounting rods has a torsion spring on its outer wall. One end of each torsion spring is fixedly connected to one side of the outer wall of the two mounting plates, and the other end of each torsion spring is fixedly connected to one side of the mounting frame's outer wall. The outer walls of the two torsion springs contact the outer walls of the two snap-fit components.
[0009] With the installation module, it can be removed from the equipment more efficiently, allowing for timely maintenance or replacement of the slide plate body, reducing equipment downtime and improving the work efficiency of the staff. At the same time, the rubber pads can reduce surface damage when fixing the slide plate body, and also reduce wear caused by vibration during use, thus extending the service life of the equipment.
[0010] In a preferred embodiment, the protective module includes four mounting blocks, all of which are fixedly connected to the top of the mounting frame. Each of the four mounting blocks has a circular groove on one outer wall, and two shaft members are movably connected inside the four circular grooves. Protective doors are fixedly connected to the outer walls of the two shaft members, and sealing gaskets are fixedly connected to one outer wall of each of the two protective doors.
[0011] By incorporating a protective module, flying sand is prevented from accumulating on the surface of the slide plate, thus extending the service life of the equipment. At the same time, flying sand is prevented from clogging the switch rails and affecting their sliding, thereby improving the device's performance.
[0012] As can be seen from the above, the turnout sand-proof slide plate device provided by this utility model can remove it from the equipment more efficiently, carry out timely maintenance or replace the slide plate body, reduce equipment downtime, improve the work efficiency of the staff, and at the same time, the rubber pad can reduce damage to its surface when fixing the slide plate body, and reduce wear caused by vibration during equipment use, thus improving the service life of the equipment.

A shaft assembly 311 is fixedly connected to one end of each rotating rod 306, and a limiting groove 312 is provided on one outer wall of each shaft assembly 311. Limit gears 305 are fixedly connected to the outer walls of each rotating rod 306, and one end of each rotating rod 306 is fixedly connected to one end of each bidirectional screw 303. The two bidirectional screws 303... The outer wall of each of the four clamping plates 301 is slidably connected to two clamping plates 301. Each of the four clamping plates 301 has a rubber pad 302 on one side of its outer wall. The outer wall of the mounting frame 313 is fixedly connected to two mounting rods 309. The outer wall of each mounting rod 309 is rotatably connected to a snap-fit piece 307. The snap-fit piece 307 is snapped into two limit gears 305 respectively. One end of each mounting rod 309 is fixedly connected to a mounting piece 310. The outer wall of each mounting rod 309 is provided with a torsion spring 308. One end of each torsion spring 308 is fixedly connected to one side of the outer wall of the two mounting pieces 310.
