Technical Field

[0001] This application relates to the field of railway rail maintenance technology, and in particular to rail support devices. Background Technology

[0002] With the rapid development of domestic railway technology, the freight volume of heavy-haul railways is constantly increasing, leading to increasingly severe rail damage and wear, and a shortened rail life. To restore seamless tracks on heavy-haul railways, flash welding and gas pressure welding are currently the main methods used. Before performing flash welding or gas pressure welding on the line, the two rails to be welded need to be supported to reach the height required for welding machine operation.

[0003] In related technologies, on-site workers mainly rely on existing support blocks when dealing with rail support issues. However, the support blocks are not standardized, requiring multiple blocks of different sizes to be carried for each operation, increasing the workload of workers and making them prone to loss or non-standard use, thus seriously affecting work efficiency and quality.

[0004] In summary, existing rail support methods suffer from inconvenience and low operational efficiency. Utility Model Content

[0005] Therefore, it is necessary to provide a rail support device to address the problems of inconvenience in use and low operating efficiency of existing rail supports.

[0007] The support section includes three different support heights and is configured to support the rail.

[0008] A locking part is movably disposed within the support part, and the locking part is configured for connection with a rail fastener.

[0009] In one embodiment, the support includes a support body, and at least one locking part is disposed on one side of the support body; the support body is configured to rotate to switch different support heights.

[0010] In one embodiment, the support body includes three support surfaces of different areas, which are arranged adjacent to each other.

[0011] In one embodiment, the support surface includes a first support surface, a second support surface, and a third support surface, wherein the first support surface is disposed at the top of the support body, and the second and third support surfaces are respectively disposed on the sides of the support body.

[0012] In one embodiment, the area of ​​the first support surface is greater than the areas of the second and third support surfaces, and the area of ​​the second support surface is greater than the area of ​​the third support surface.

[0014] In one embodiment, the support body has a mounting groove on one side; the locking part includes a slider and a hook, the slider is slidably disposed in the mounting groove, and the hook is disposed at the end of the slider away from the support body.

[0015] In one embodiment, the support body is further provided with a sliding groove, which is disposed on one side of the mounting groove;

[0016] The locking part includes a slide rod, which is vertically disposed on one side of the slider. One end of the slide rod is mounted on the slider, and the other end of the slide rod is slidably connected to the slide groove.

[0017] In one embodiment, one end of the hook is configured as an arc-shaped structure.

[0018] In one embodiment, three locking parts are also included, one of which is disposed on the first support surface, and the other two of which are disposed perpendicularly to each other on the second support surface.

[0032] To restore seamless track on heavy-haul railways, on-line flash welding and gas pressure welding have become crucial methods. Before operation, the two rails to be welded need to be supported to achieve the welding machine's operating height. However, the support blocks currently used on-site are non-standard, requiring operators to carry various sizes of support blocks, leading to inconvenience, management difficulties, easy loss, and non-standard usage, severely impacting work efficiency and quality.

[0033] See Figure 1 , Figure 2 , Figure 1 A schematic diagram of the rail support device according to one embodiment of this application is shown. Figure 1 . Figure 2 A schematic diagram of the rail support device according to one embodiment of this application is shown. Figure 2 .

[0034] To solve the above-mentioned technical problems, an embodiment of this application provides a rail support device, including a support part 10 and a locking part 20. The support part 10 has three different support heights to meet the needs of different support specifications in actual operation; the locking part 20 is connected to the rail fastener to ensure the stability of the support.

[0035] In this embodiment, the support portion 10 includes three different support heights and is configured to support the rail. A locking portion 20 is movably disposed within the support portion 10 and is configured to connect with a rail fastener.

[0036] The support part 10 is rectangular in shape and made of alloy steel. It has high strength, high hardness and good wear resistance. It can withstand the weight of the rail and various stresses generated during operation, ensuring the stability and durability of the device.

[0037] The support section 10 has three different support heights. The interior of the support section 10 is a hollow structure, divided into three support areas corresponding to support heights of 100mm, 150mm, and 180mm respectively. By changing the placement of each support area, the vertical height of the support section 10 can be altered to meet the different height requirements before rail welding.

[0038] The locking part 20 is movably disposed within the support part 10. The locking part 20 is located on the side of the support part 10 closest to the rail fastener and is slidably connected to the support part 10. By sliding the locking part 20, the distance between the locking part 20 and the rail fastener is adjusted to achieve the locking action, preventing the support part 10 from shifting during welding and improving stability. Simultaneously, it meets the fixing requirements of rails at different distances.

[0039] The locking part 20 is made of metal. The part of the locking part 20 that contacts the rail fastener is treated with anti-slip material to increase friction with the rail fastener and improve the stability of locking.

[0040] In practice, the height of the support section 10 can be adjusted by the operator according to the required rail support height. For example, when a 100mm support height is needed, the operator rotates the support section 10 to keep the 100mm portion of the support section 10 vertical, thus adjusting the vertical height of the support section 10 to 100mm. When 150mm or 180mm is required, the support section 10 is rotated accordingly to adjust the support height. The entire switching process is simple and quick, eliminating the need for operators to carry multiple support blocks of different specifications, thereby improving work efficiency.

[0041] After adjusting the support height of the support part 10, pull the locking part 20 to move it closer to the rail and connect it with the rail fastener to achieve a locked state, effectively preventing the support part 10 from shifting during operation and ensuring the stability of the support.

[0042] As described above, to meet the welding requirements of rails at different heights, the support part 10 can be rotated to switch between different support heights, thus supporting the rails and improving welding efficiency. Simultaneously, the locking part 20 can be moved to connect with the rail fastener, locking the two together and preventing displacement of the support part 10 during operation, thereby improving the stability and quality of the welding operation. Furthermore, operators only need to carry one rail support device to meet their support requirements, reducing their workload.

[0043] Combination Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the rail support device provided in one embodiment of this application. Figure 2 In some embodiments, the support portion 10 includes a support body 11. The support body 11 has a cuboid structure, and its surface is anodized to enhance wear resistance and corrosion resistance.

[0044] In one embodiment, the support body 11 includes three support surfaces of different areas, which are arranged adjacent to each other. The support body 11 is configured to rotate to switch between different support heights.

[0045] Specifically, the support body 11 includes three support surfaces of different areas, which are arranged adjacently on three adjacent sides of a cuboid. The different areas of the three support surfaces mean that their lengths are also different. When the support height needs to be adjusted, by keeping one of the support surfaces vertical, the length of that support surface can be used as the vertical height, thus changing the support height of the support body 11 and meeting the requirements for different rail support heights.

[0046] In one embodiment, at least one locking part 20 is provided on one side of the support body 11.

[0047] Specifically, one locking part 20 is provided on one side of the support body 11. When the support body 11 is adjusted to the support height, the locking part 20 is connected to the rail fastener to achieve locking. Alternatively, two locking parts 20 are provided on the two sides of the support body 11 respectively. After the support body 11 is rotated to adjust the support height, one locking part 20 can still be connected to the rail fastener to meet the locking requirements.

[0048] In one embodiment, the support surface includes a first support surface 121, a second support surface 122, and a third support surface 123. The first support surface 121 is disposed at the top of the support body 11, and the second support surface 122 and the third support surface 123 are respectively disposed on the side of the support body 11.

[0049] Specifically, the first support surface 121 is located at the top of the support body 11, and its area is relatively large. The top of the support body 11 refers to the end face with the largest support area. The first support surface 121 may be provided with anti-slip textures, which are distributed in a regular grid pattern, effectively increasing the friction between the support surface and the rail, preventing the rail from sliding during the support process, and ensuring operational safety.

[0050] The second support surface 122 is provided on one side of the support body 11. The second support surface 122 is used to accommodate rails with small support area requirements.

[0051] The third support surface 123 is located on the other side of the support body 11 adjacent to the second support surface 122. By rotating the support body 11, the first support surface 121, the second support surface 122, or the third support surface 123 can be brought into contact with the rail to switch different support heights.

[0052] In one embodiment, the area of ​​the first support surface 121 is greater than the areas of the second support surface 122 and the third support surface 123, and the area of ​​the second support surface 122 is greater than the area of ​​the third support surface 123.

[0053] Specifically, the first support surface 121 has the largest area, with a length of 180 mm and a width of 150 mm, totaling 27,000 square millimeters. The second support surface 122 has a smaller area, with a length of 180 mm and a width of 100 mm, totaling 18,000 square millimeters. The third support surface 123 has the smallest area, with a length of 150 mm and a width of 100 mm, totaling 15,000 square millimeters.

[0054] Each support surface has a different height perpendicular to the rail placement direction. When the first support surface 121 faces upward, the support height is 100mm. When the second support surface 122 faces upward, the support height is 150mm. When the third support surface 123 faces upward, the support height is 180mm. Operators can manually rotate the support body 11 to switch between different support surfaces according to the site requirements for different rail support heights.

[0055] Combination Figure 3 , Figure 4 As shown, Figure 3 This is a schematic diagram of the structure of the rail support device provided in one embodiment of this application. Figure 3 . Figure 4 This is a schematic diagram of the locking part 20 provided in one embodiment of this application. In some embodiments, a mounting groove 13 is provided on one side of the support body 11; a sliding groove 14 is also provided inside the support body 11, and the sliding groove 14 is disposed on one side of the mounting groove 13.

[0056] Specifically, the support body 11 has a mounting groove 13 on one side, and the mounting groove 13 has a rectangular structure. The two side walls of the mounting groove 13 provide guidance for the movement of the locking part 20.

[0057] A sliding groove 14 is provided on one side of the mounting groove 13. The sliding groove 14 is parallel to the mounting groove 13 and has a long strip structure.

[0058] In one embodiment, the locking part 20 includes a slider 21 and a hook 22. The slider 21 is slidably disposed within the mounting groove 13, and the hook 22 is disposed at the end of the slider 21 away from the support body 11. A sliding rod 23 is vertically disposed on one side of the slider 21, with one end of the sliding rod 23 mounted on the slider 21 and the other end of the sliding rod 23 slidably connected to the sliding groove 14.

[0059] Specifically, the locking part 20 consists of a slider 21, a hook 22, and a sliding rod 23. The slider 21 is rectangular in shape and matches the mounting groove 13. The slider 21 slides along the axial direction of the mounting groove 13 within the mounting groove 13 to adjust the distance between the hook 22 and the rail fastener.

[0060] The hook 22 is located at the end of the slider 21 away from the support body 11. It is made of spring steel and has both elasticity and strength. The hook 22 has an L-shaped structure. One end of the hook 22 is fixedly connected to the slider 21 by bolts, or the hook 22 and the slider 21 are integrally formed.

[0061] The other end of the hook 22 is bent into an arc shape, which better conforms to the shape of the rail fastener and improves the locking effect. The surface of the arc shape is treated with an anti-slip coating to increase friction and enhance connection stability.

[0062] The slide bar 23 is vertically mounted on one side surface of the slider 21. One end of the slide bar 23 is fixed to the slider 21 by welding, and the other end of the slide bar 23 is inserted into the slide groove 14 and slidably connected with the slide groove 14. The length of the slide groove 14 limits the movement distance of the slider 21 and also limits the movement of the slide bar 23, preventing the slide bar 23 from swinging and improving the stability and smoothness of the slider 21 sliding.

[0063] In one embodiment, three locking parts 20 are also included, one of which is disposed on the first support surface 121, and the other two are disposed perpendicularly to each other on the second support surface 122.

[0064] Specifically, the locking part 20 on the first support surface 121 includes a slider 21, a hook 22, and a slide rod 23. The two locking parts 20 on the second support surface 122 also include a slider 21, a hook 22, and a slide rod 23. The installation directions of the two locking parts 20 on the second support surface 122 are perpendicular to each other, meaning that the movement directions of the two locking parts 20 are perpendicular to each other; one locking part 20 moves along the length direction of the second support surface 122, and the other locking part 20 moves along the width direction of the second support surface 122. The two locking parts 20 cooperate to lock the rail fasteners in different directions.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
