Description

Technical Field

[0001] The utility model relates to the technical field related to railway tracks, in particular to a rail support fastener device for a steel rail turnout slide bed plate. Background Art

[0002] With the rapid development of rail transit, more and more urban rail transit lines are laid using elevated lines, ground lines, etc., and more and more lines pass through residential areas and densely populated areas. However, when vehicles are running, the collision between the wheels and the rails causes the rails to vibrate more, and the resulting noise radiation affects people's normal lives; the increased vibration of the rails also aggravates the increase in the wheel-rail impact force, causing damage such as wavy wear of the rails, which greatly increases the maintenance work and cost of the rail lines.

[0003] The Chinese patent CN220952733U authorized and announced on May 14, 2024 discloses a turnout slide bed plate that coordinates the deformation of the point rail, wherein the deformation capacity of the point rail and the base rail is made consistent by vulcanizing and bonding the first rubber pad under the slide bed plate, so as to achieve coordinated deformation of the point rail and the base rail. The problem of excessive force on the point rail and the occurrence of defects such as peeling off of blocks due to excessive rigidity of the slide bed and uncoordinated deformation is avoided. The utility model directly replaces the existing slide bed plate structure at the construction site, which is convenient for renovation and construction. However, during the use of the turnout slide bed plate that coordinates the deformation of the point rail, when the train passes over the surface of the rail, it will vibrate the rail palm bolts, and the rail palm bolts are easily loosened due to the influence of the vibration load. Once the rail palm bolt connection structure is loosened, it will cause the rail palm to loosen, causing the gauge of the rail to change, and the train is very likely to derail, making it still inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a rail support fastener device for a turnout slide bed of a steel rail, so as to solve the problem that the existing turnout slide bed with coordinated deformation of the point rail proposed in the above-mentioned background technology will vibrate the rail palm bolts when a train passes over the surface of the rail during use, and the rail palm bolts are easily loosened due to the influence of the vibration load. Once the rail palm bolt connection structure is loosened, the rail palm will become loose, resulting in a change in the gauge of the rail, and the train is very likely to derail, making it still inconvenient to use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rail support fastener device for a steel rail switch slide bed plate, comprising an iron pad, the surface of the iron pad is fixedly connected to a slide bed plate, the outer wall of the slide bed plate is penetrated by a sleeper bolt, one end of the sleeper bolt is threadedly connected to a sleeper on the outer wall, the outer wall of the iron pad is connected to a basic rail, the outer wall of the iron pad is penetrated by a rail palm bolt, and one end of the rail palm bolt is threadedly connected to the sleeper, the outer wall of the rail palm bolt is penetrated by a rail palm, the surface of the rail palm is equipped with a limiting component, a slot is provided on the outer wall of the rail palm bolt, and the surface of the slide bed plate is slidably connected to a point rail.

[0006] Preferably, the limit assembly includes a fixed block, which is mounted on the surface of the rail palm, a limit hole is provided on the outer wall of the fixed block, a spring sheet is fixedly connected to the outer wall of the fixed block, a rotating block is rotatably connected to the outer wall of the fixed block, a sliding groove is provided on the outer wall of the rotating block, the interior of the sliding groove is slidably connected to a limit column, one end of the limit column is fixedly connected to a rotating sleeve, and a clamping block is fixedly connected to the outer wall of one end of the rotating block.

[0007] Preferably, a plurality of anti-slip grooves are provided on the outer wall of the rotating sleeve.

[0008] Preferably, a notch is provided on the outer wall of the rotating block, and the size of the notch is larger than the surface diameter of the limiting column.

[0009] Preferably, a limiting block is fixedly connected to the outer wall of the limiting column, a limiting groove is provided on the inner wall of the rotating block, and the inner wall of the limiting groove is slidably connected to the limiting block.

[0010] Preferably, a plurality of groups of threaded holes are provided on the outer wall of the sleeper, and the sleeper bolts are threadedly connected to the sleeper through the threaded holes.

[0011] Preferably, a nut is fixedly connected to the top end of the rail palm bolt, and an elastic strip is connected to the surface of the rail palm.

[0012] Preferably, a rubber pad is bonded to the bottom end of the iron pad.

[0013] Preferably, a groove is formed at one end of the slide bed plate.

[0014] The difference from the prior art lies in that the beneficial effect of the present application lies in that: when installing the rail palm bolt, the clamping block is squeezed by the rail palm bolt so that the rotating block rotates on the surface of the fixed block and squeezes the spring sheet. When the rail palm bolt is completely connected to the sleeper, the spring sheet pushes the rotating block so that the clamping block is clamped into the inside of the clamping slot and limits the rail palm bolt to prevent the rail palm bolt from loosening due to vibration generated when a train passes. When removing the rail palm bolt, the limiting column slides inside the slide slot to push the rotating block to rotate on the surface of the fixed block and cause the clamping block to slide out of the inside of the clamping slot, thereby releasing the limit on the rail palm bolt. The rotating sleeve is pressed to slide the limiting column into the inside of the limiting hole, thereby limiting the rotating block and the clamping block to ensure stability when removing the rail palm bolt.

Through the setting of the threaded holes 5, the sleeper bolts 3 pass through the iron pad 1 and are threadedly connected to the threaded holes 5, thereby fixing the iron pad 1 on the surface of the sleeper 4. At the same time, the setting of the plurality of groups of threaded holes 5 can improve the stability of the iron pad 1 after being connected to the sleeper 4.

[0038] In this embodiment, a nut 11 is fixedly connected to the top of the rail palm bolt 7, and an elastic bar 12 is connected to the surface of the rail palm 8.

[0039] In this embodiment, a rubber pad 14 is bonded to the bottom end of the iron pad 1. Through the provision of the rubber pad 14, the rubber pad 14 can increase the friction between the iron pad 1 and the sleeper 4, thereby improving the stability of the connection between the iron pad 1 and the sleeper 4.

[0040] In this embodiment, a groove 15 is provided at one end of the slide bed platen 2. Through the setting of the groove 15, when the slide bed platen 2 is installed, the groove 15 will be stuck in one end of the basic rail 6, and cooperate with the rail palm 8 to squeeze the other end of the basic rail 6, thereby limiting the basic rail 6.

[0041] Working principle: First, the iron pad 1 is fixed to the surface of the sleeper 4 through the threaded connection between the sleeper bolt 3 and the threaded hole 5, and then the rail palm 8 is placed on the surface of the basic rail 6, and then the elastic bar 12 is placed on the surface of the rail palm 8, and the rail palm bolt 7 is passed through the surface of the rail palm 8 and threadedly connected to the sleeper 4, so that the nut 11 squeezes the surface of the elastic bar 12, thereby fixing the elastic bar 12 on the surface of the rail palm 8. When the rail palm bolt 7 passes through the rail palm 8 and is threadedly connected to the sleeper 4, the rail palm bolt 7 will squeeze the block 912 to make the rotating block 904 rotate on the surface of the fixed block 901 and squeeze the spring sheet 903. When the rail palm bolt 7 is completely connected to the sleeper 4, the groove 10 on the surface of the rail palm bolt 7 is just kept on the same horizontal line with the block 912. At this time, the external force of the spring sheet 903 pushes the rotating block 904 to rotate on the surface of the fixed block 901, so that the block 9 12 is inserted into the interior of the slot 10 and limits the rail palm bolt 7 to prevent the rail palm bolt 7 from loosening due to the vibration generated when the train passes. When removing the rail palm bolt 7, first rotate the rotating sleeve 907 to drive the limiting column 906 to slide inside the slide slot 905. Through the sliding of the limiting column 906 inside the slide slot 905, the rotating block 904 is pushed to rotate on the surface of the fixed block 901, so that the blocking block 912 slides out of the interior of the slot 10, thereby releasing the limitation of the rail palm bolt 7. When the limiting column 906 slides to the other end of the slide slot 905, it moves to the surface of the limiting hole 902, and the rotating sleeve 907 is pressed to slide the limiting column 906 into the interior of the limiting hole 902, thereby limiting the rotating block 904 and the blocking block 912 to ensure stability when removing the rail palm bolt 7. In this way, the use process of the rail switch slide bed rail support fastener device is completed.

[0042] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and the concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
