Description

Technical Field

[0001] This utility model relates to the field of rail welding technology, and more specifically, to an adjustable rail low-damping moving support. Background Technology

[0002] With the increasing operating time and freight volume of existing railway lines in my country, rail wear is becoming increasingly serious. To ensure the safe, stable and reliable operation of railways, rail welding and additive repair are important links in laying seamless railway tracks and are an important guarantee for the safety of train operation.

[0003] For high-speed railway lines, the length of damaged rails to be replaced must not be less than 20 meters, while for conventional railway lines, the length must not be less than 6.25 meters. Before the rail movement and welding operation, the rails to be replaced are unloaded by a rail unloading vehicle to the construction position. On high-speed lines, they are generally unloaded into a ditch outside the track, while on conventional lines, they are generally unloaded to the center of the track. However, there is a certain error between the unloading position and the actual replacement position, requiring temporary adjustments to the rail's position during construction. Taking high-speed railway construction as an example, the replaced rails are generally 25-meter standard length rails, weighing up to 1500 kg. The rail unloading vehicle usually unloads the rails to the construction position in advance. When the rail is far from the specific construction position and there is a need for height adjustment, it is difficult for on-site workers to adjust the position of long rails.

[0004] On the one hand, when conducting rail welding parameter adjustment tests in the laboratory environment, the limited space makes it impossible to use traditional cranes, and it is difficult to move and adjust long rails onto the welding platform. On the other hand, rail additive repair technology is still in the laboratory research and development stage. When there is low slump wear at the weld seam of the rail, the rail needs to be sawn off, sent to the laboratory environment for additive repair, and then transported back to the site for on-site mobile welding. The sawn rail is nearly 10 meters long, the additive repair work platform has a certain height, and the laboratory environment is relatively narrow, making it difficult to place the rail on the additive repair work platform using only lifting equipment.

[0005] Existing methods use cranes in conjunction with stress relief rollers to adjust the position of the rails. However, in confined spaces such as factory and laboratory environments, cranes are not readily available on-site. Furthermore, the existing stress relief rollers have limited height, which cannot meet the need for moving and adjusting the rails on a working platform at a certain height. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose an adjustable rail low-damping moving support so that the rail can be moved and adjusted on a working platform with a certain height.

[0007] Based on the above objectives, this utility model provides an adjustable rail small-damping movable support, including a height adjustment component, a small damping component, and two opposing support components. The support components include a first vertical tube and a base. The height adjustment component includes a crossbeam and two opposing second vertical tubes. The two ends of the crossbeam are respectively mounted on the two second vertical tubes, and the two second vertical tubes are respectively fitted onto the outer walls of the two first vertical tubes, with the second vertical tubes being slidable along the height direction of the first vertical tubes. The small damping component includes a mounting base, a roller, a rotating shaft, and a first limiting component and a second limiting component located at both ends of the small damping component. The small damping component is mounted on the crossbeam. The first limiting component includes a first vertical plate, and the second limiting component includes a second vertical plate. The distance between the first and second vertical plates is greater than the rail base width. The mounting base includes a mounting platform located between the first and second vertical plates. The roller contains a bearing for use with the rotating shaft. The rotating shaft passes through the bearing and is rotatably mounted on the mounting platform, rotating together with the roller.

[0008] Optionally, it also includes a first pin, the first vertical tube has a plurality of first mounting holes, the second vertical tube has a plurality of second mounting holes, the distance between two adjacent first mounting holes is equal to the distance between two adjacent second mounting holes, and the first pin passes through one of the second mounting holes and the corresponding first mounting hole to mount the second vertical tube on the outer wall of the first vertical tube.

[0009] Optionally, it also includes a second pin and a third pin. The crossbeam is provided with a first positioning hole and a second positioning hole. The first limiting member also includes a first horizontal plate connected to the first vertical plate. The first horizontal plate is provided with a first limiting hole corresponding to the first positioning hole. The second limiting member also includes a second horizontal plate connected to the second vertical plate. The second horizontal plate is provided with a second limiting hole corresponding to the second positioning hole. The second pin passes through the first limiting hole and the first positioning hole in sequence, and the third pin passes through the second limiting hole and the second positioning hole in sequence, and then the small damping member is installed on the crossbeam.

[0010] Optionally, the height adjustment component further includes a plurality of reinforcing ribs, one end of which is mounted on the crossbeam and the other end of which is mounted on the second vertical pipe.

[0011] Optionally, the base is provided with multiple stiffening plates.

[0012] Optionally, the two ends of the crossbeam are respectively vertically mounted on the two second vertical pipes.

[0013] Optionally, there are two rollers, namely a first roller and a second roller, two rotating shafts, namely a first rotating shaft and a second rotating shaft, and two mounting platforms, namely a first mounting platform and a second mounting platform. The first roller is rotatably mounted on the middle of the first mounting platform via the first rotating shaft, and the second roller is rotatably mounted on the middle of the second mounting platform via the second rotating shaft. One end of the first mounting platform is mounted on the first vertical plate, and one end of the second mounting platform is mounted on the second vertical plate.

[0014] The adjustable rail damping movable support provided by this utility model first involves placing the base on the ground, then mounting two second vertical tubes onto the outer walls of the two first vertical tubes, with the positions of the second vertical tubes on the first vertical tubes determined according to the required height. Next, the damping element is mounted on the crossbeam of the height adjustment component, completing the assembly of the two adjustable rail damping movable supports. Finally, one end of the rail is placed on the first damping element, and the bottom of the rail is lowered between the first and second vertical plates to prevent slippage. The bottom of the rail is placed on the rollers to minimize resistance when moving along its length. The rail is then pushed along the target direction, causing the bottom of the other end to rest on the rollers of the second damping element, ensuring the rail falls onto the two adjustable rail damping movable supports. This allows the rail to be moved and adjusted on a work platform of a certain height until it reaches the target position. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] like Figures 1 to 5 As shown, the adjustable rail small-damping movable support provided by this utility model includes a height adjustment component 1, a small-damping component 2, and two opposing support components 3. The support component 3 includes a first vertical tube 4 and a base 5. The height adjustment component 1 includes a crossbeam 6 and two opposing second vertical tubes 7. The two ends of the crossbeam 6 are respectively mounted on the two second vertical tubes 7. The two second vertical tubes 7 are respectively fitted onto the outer walls of the two first vertical tubes 4, and the second vertical tubes 7 are slidable along the height direction of the first vertical tubes 4. The small-damping component 2 includes a mounting base 8, rollers, and... The rotating shaft and the first limiting member 10 and the second limiting member 11 are located at both ends of the small damping member 2. The small damping member 2 is installed on the crossbeam 6. The first limiting member 10 includes a first vertical plate 12, and the second limiting member 11 includes a second vertical plate 13. The distance between the first vertical plate 12 and the second vertical plate 13 is greater than the bottom width of the rail 30. The mounting base 8 includes a mounting platform located between the first vertical plate 12 and the second vertical plate 13. The roller is equipped with a bearing that is compatible with the rotating shaft. After passing through the bearing, the rotating shaft is rotatably mounted on the mounting platform. The rotating shaft and the roller rotate together.

[0025] The adjustable rail small-damping movable support provided by this utility model first involves placing the base 5 on the support member 3 on the ground, and then correspondingly installing the two second vertical pipes 7 onto the outer walls of the two first vertical pipes 4, determining the position of the second vertical pipes 7 on the first vertical pipes 4 according to the required height. Next, the small damping member 2 is installed on the crossbeam 6 of the height adjustment member 1, completing the assembly of the two adjustable rail small-damping movable supports. Finally, one end of the rail 30 is placed on the first small damping member 2, and the rail 30 is... The bottom of the rail 30 falls between the first vertical plate 12 and the second vertical plate 13, ensuring that the rail 30 does not slip out. Placing the bottom of the rail 30 on the rollers reduces the resistance when the rail 30 moves along its length. Pushing the rail 30 along the target direction causes the bottom of the other end of the rail 30 to be placed on the roller of the second small damping component 2, ensuring that the rail 30 falls onto the two adjustable small damping moving supports. This allows the rail 30 to be moved and adjusted on a working platform with a certain height until it reaches the target position.

[0026] It should be noted that the adjustable rail small damping moving bracket can be moved manually; one end of the rail 30 can be placed on the first adjustable rail small damping moving bracket through the hanger.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a first pin 9. The first vertical tube 4 has multiple first mounting holes 16, and the second vertical tube 7 has multiple second mounting holes 17. The distance between two adjacent first mounting holes 16 is equal to the distance between two adjacent second mounting holes 17. The first pin 9 passes through one of the second mounting holes 17 and the corresponding first mounting hole 16, and then mounts the second vertical tube 7 onto the outer wall of the first vertical tube 4. In this embodiment, the second vertical tube 7 is slid to the required position on the outer wall of the first vertical tube 4 according to the height requirement. When the rail 30 is placed on the small damping component 2, the height of the rail 30 relative to the ground is adjustable. The second vertical tube 7 is fixed to the first vertical tube 4 by the first pin 9, thereby fixing the height adjustment component 1 onto the support component 3, improving the ease of installation or disassembly of the adjustable rail small damping moving bracket.

[0028] like Figure 1 and Figure 4As shown, it also includes a second pin 18 and a third pin 19. The crossbeam 6 has a first positioning hole 20 and a first positioning hole 21. The first limiting member 10 also includes a first horizontal plate 22 connected to the first vertical plate 12. The first horizontal plate 22 has a first limiting hole 24 corresponding to the first positioning hole 20. The second limiting member 11 also includes a second horizontal plate 23 connected to the second vertical plate 13. The second horizontal plate 23 has a second limiting hole 25 corresponding to the first positioning hole 21. The second pin 18 passes through the first limiting hole 24 and the first positioning hole 20 in sequence, and the third pin 19 passes through the second limiting hole 25 and the first positioning hole 21 in sequence before mounting the small damping member 2 on the crossbeam 6. In this embodiment, the small damping member 2 is fixedly mounted on the height adjusting member 1 by the second pin 18 and the third pin 19, improving the ease of installation or disassembly of the adjustable rail small damping moving bracket.

[0029] like Figure 3 As shown, the height adjustment component 1 also includes multiple reinforcing ribs 26. One end of each reinforcing rib 26 is mounted on the crossbeam 6, and the other end is mounted on the second vertical pipe 7. In this embodiment, the reinforcing ribs 26 increase the structural strength of the height adjustment component 1, thereby improving the structural strength of the adjustable rail small damping moving support.

[0030] like Figure 2 As shown, the base 5 is provided with multiple stiffening plates 27. In this embodiment, the stiffening plates 27 increase the structural strength of the base 5, thereby improving the structural strength of the support member 3.

[0031] like Figure 1 and Figure 3 As shown, the two ends of the crossbeam 6 are respectively vertically mounted on the two second vertical pipes 7. In this embodiment, when the small damping element 2 is placed on the crossbeam 6 and the rail 30 is placed on the small damping element 2, the rail 30 is prevented from tilting and sliding off the small damping element 2, thus improving the structural stability of the adjustable rail small damping moving support.

[0032] like Figure 4 and Figure 5 As shown, there are two rollers, namely the first roller 28 and the second roller 29, and two rotating shafts, namely the first rotating shaft and the second rotating shaft. There are two mounting platforms, namely the first mounting platform 14 and the second mounting platform 15. The first roller 28 is rotatably mounted on the middle of the first mounting platform 14 via the first rotating shaft, and the second roller 29 is rotatably mounted on the middle of the second mounting platform 15 via the second rotating shaft. One end of the first mounting platform 14 is mounted on the first vertical plate 12, and one end of the second mounting platform 15 is mounted on the second vertical plate 13. In this embodiment, when the rail 30 is placed on the first roller 28 and the second roller 29, the rail 30 can move more conveniently in the longitudinal direction.

[0033] The adjustable rail small-damping movable support provided by this utility model first involves placing the base 5 on the support member 3 on the ground, and then correspondingly installing the two second vertical pipes 7 onto the outer walls of the two first vertical pipes 4, determining the position of the second vertical pipes 7 on the first vertical pipes 4 according to the required height. Next, the small damping member 2 is installed on the crossbeam 6 of the height adjustment member 1, completing the assembly of the two adjustable rail small-damping movable supports. Finally, one end of the rail 30 is placed on the first small damping member 2, and the rail 30 is... The bottom of the rail 30 falls between the first vertical plate 12 and the second vertical plate 13, ensuring that the rail 30 does not slip out. Placing the bottom of the rail 30 on the rollers reduces the resistance when the rail 30 moves along its length. Pushing the rail 30 along the target direction causes the bottom of the other end of the rail 30 to be placed on the roller of the second small damping component 2, ensuring that the rail 30 falls onto the two adjustable small damping moving supports. This allows the rail 30 to be moved and adjusted on a working platform with a certain height until it reaches the target position.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
