Description

Technical Field

[0001] This utility model relates to the field of railway maintenance technology; specifically, this utility model relates to a rail fixing and reinforcement device for railway line maintenance. Background Technology

[0002] Rail welding repair is one of the core maintenance projects for railway lines and a crucial aspect of ensuring railway safety. When a rail experiences a localized break or develops a large crack, rail reinforcement tools are used to align the two sections of rail that are cracked or broken before welding is performed.

[0003] For example, patent application number 202221649813.X provides a rail fixing and reinforcement device for railway line maintenance, including a support frame. Both sides of the front portion of the support frame's inner cavity are fixedly connected to a first sliding plate via a fixing plate. A first slider is slidably installed inside the first sliding plate, and a linkage box is fixedly connected to the rear of the first slider. This utility model relates to the field of railway maintenance technology. This rail fixing and reinforcement device for railway line maintenance, by providing two sets of clamping plates on the inner side of the support frame, allows the two clamping plates in the same set to be closed by cranking a handle to clamp the rail. Then, rotating the turntable allows the two broken rail sections to be pulled up through the action of a second threaded rod and a threaded cylinder, avoiding the process of transporting load-bearing rails. Simultaneously, slowly rotating the second threaded rod allows for fine adjustment, ensuring that the two broken rail sections can completely overlap, thereby improving the quality of the weld.

[0004] While the aforementioned existing technologies can achieve rail alignment to some extent, they have at least the following drawbacks:

[0005] (1) When using arc welding to repair rails, the existing technology described above requires separate operations for aligning the rails in the left and right directions and in the height direction, which makes the operation process complicated.

[0006] (2) The above-mentioned existing technology can only be applied to one type of operation of arc welding for rail repair. However, in actual situations, when there is no external power supply in the rail repair operation and the rail needs to be repaired by aluminothermic welding, the above-mentioned rail fixing and reinforcement device can only clamp and fix the rail, but cannot provide effective assistance for the fixing and positioning of the aluminothermic mold, resulting in certain limitations. Utility Model Content

[0007] In view of this, the present invention provides a rail fixing and reinforcement device for railway line maintenance, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0008] To achieve the aforementioned objectives, this utility model provides a rail fixing and reinforcement device for railway line maintenance, comprising:

[0009] Two supports are arranged opposite each other, the supports are able to span the top of the rail, and the distance between the two supports is adjustable;

[0010] A backing plate is provided at one end of the bracket and can rest against the side of the rail web or the surface of one of the aluminothermic molds. The backing plate is configured to be able to move outward to the farthest position on the bracket first and then move upward.

[0011] The top plate, located at the other end of the support, can rest against the other side of the rail web or the surface of another aluminothermic mold. The top plate can apply a thrust to the rail or aluminothermic mold by continuously displacing in an upwardly inclined direction towards the inside of the support.

[0012] In the aforementioned rail fixing and reinforcement device for railway line maintenance, optionally, a sliding rod and a double-ended screw rod are also included. The sliding rod connects one end of the two supports corresponding to the back plate, and the sliding rod and the supports are in sliding fit.

The screw rod is threaded through the screw sleeve, and the top plate is hinged to the inner end of the screw rod.

[0014] In the aforementioned rail fixing and reinforcement device for railway line maintenance, optionally, an "L"-shaped track is fixedly installed at the bottom of one end of the bracket corresponding to the sliding rod, and a slider is provided at the outer end of the backing plate, and the slider is slidably installed inside the track.

[0015] In the rail fixing and reinforcement device for railway line maintenance as described above, optionally, rollers that reduce the friction between the slider and the outer inner wall surface are provided at equal intervals on the outer inner wall surface of the rail.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1 to 4 As shown, a typical embodiment of this utility model provides a rail fixing and reinforcement device for railway line maintenance, including a bracket 1, a backing plate 2 and a top plate 3.

[0027] Two supports 1 are provided, arranged opposite each other. Each support 1 spans the top of the rail, and the distance between them is adjustable to accommodate both arc welding and aluminothermic welding methods for rail repair. Specifically, when using arc welding, the distance between the two supports 1 is larger to facilitate the welding operation. When using aluminothermic welding, the distance between the two supports 1 is smaller to facilitate the aluminothermic welding operation.

[0028] The abutment plate 2 is disposed at one end of the support 1 and can rest against the side of the rail web or the surface of one of the aluminothermic molds. The abutment plate 2 is configured to first move outward to the farthest position on the support 1 and then move upward. Specifically, the outward movement of the abutment plate 2 corresponds to the outward movement of the rail and / or the aluminothermic mold, and the upward movement of the abutment plate 2 corresponds to the upward movement of the rail and / or the aluminothermic mold.

[0029] The top plate 3 is located at the other end of the support 1 and can rest against the other side of the rail web or the surface of another aluminothermic mold. The top plate 3 can apply a thrust to the rail or aluminothermic mold by continuously moving inward toward the support 1 in an upward tilting direction.

[0030] In this embodiment, when repairing the rail using arc welding, the top plate 3 directly contacts the other side of the rail web and applies a pushing force to the rail. During this process, the rail first moves horizontally to the opposite side until the abutment plate 2 moves outward to its furthest distance. Then, the top plate 3 applies a pushing force to the rail using its upward tilting displacement. The support 1 experiences a reaction force and moves downward, causing the two supports 1 to abut against the tops of the two rail sections respectively. At this point, utilizing the flush property of the two supports 1, the two rail sections are aligned in both the left-right and height directions, ensuring the accuracy of the rail repair welding.

[0031] When repairing rails using aluminothermic welding, the backing plate 2 and the top plate 3 respectively contact the outer surfaces of the two aluminothermic molds, with the top plate 3 applying a pushing force to the molds it contacts. During this process, the rail and the two aluminothermic molds as a whole shift towards the backing plate 2 and press against it. When the backing plate 2 moves to its furthest position, the two aluminothermic molds are in a tightly closed, pressed state. Then, as the top plate 3 applies a pushing force to the aluminothermic molds and rails through its upward tilting displacement, the support 1 experiences a reaction force and shifts downwards, causing the two supports 1 to abut against the tops of the two rail sections. At this point, utilizing the flush property of the two supports 1, the two rail sections are aligned in both the left-right and height directions, and the two aluminothermic molds remain stable in a closed, tightly pressed state, ensuring the precision of the rail repair welding.

[0032] In a relatively specific embodiment, the rail fixing and reinforcement device for railway line maintenance further includes a sliding rod 4 and a double-acting screw 5. The sliding rod 4 connects the two supports 1 to one end corresponding to the backing plate 2, and the sliding rod 4 and the supports 1 are in a sliding fit. The double-acting screw 5 connects the two supports 1 to one end corresponding to the top plate 3, and the double-acting screw 5 and the supports 1 are in a threaded fit. By setting the sliding rod 4 and the double-acting screw 5, the two supports 1 are kept in an aligned state at all times. On the other hand, by rotating the double-acting screw 5, the distance between the two supports 1 can be adjusted to suit both arc welding and aluminothermic welding rail maintenance methods.

[0033] In a relatively specific embodiment, the rail fixing and reinforcement device for railway line maintenance further includes a collar 6, a threaded sleeve 7, and a screw 8. The collar 6 is rotatably sleeved on the end of the bracket 1 that is sleeved on the double-acting screw 5. The threaded sleeve 7 is fixedly connected to the collar 6. The screw 8 is threaded through the threaded sleeve 7, and the top plate 3 is hinged to the inner end of the screw 8. With this configuration, the screw 8 can rotate relative to the double-acting screw 5, and the top plate 3 can rotate relative to the screw 8. By utilizing the rotation of the collar 6 on the threaded sleeve 7, the orientation of the screw 8 can be adjusted according to the lateral and vertical movement of the rail, thereby adjusting the direction of the thrust applied by the top plate 3 to the rail, so as to better achieve the clamping and positioning of the rail in the left-right and vertical directions. At the same time, when adjusting the distance between the two brackets 1, the distance between the two top plates 3 and the distance between the two abutment plates 2 are adjusted synchronously.

[0034] The bracket 1 has an L-shaped track 9 fixedly installed at one end of the slide bar 4. A slider 10 is installed on the outer end of the backing plate 2, and the slider 10 is slidably positioned within the track 9. The cooperation of the track 9 and the slider 10 allows the backing plate 2 to stably move laterally relative to the bracket 1, ensuring that the rails are aligned in the left-right direction and that the two aluminothermic molds are in a tightly closed state before being clamped, fixed, and aligned in the height direction. Rollers 11, equidistantly arranged on the inner outer wall of the track 9, reduce the friction between the slider 10 and its inner outer wall.

[0035] In a relatively specific embodiment, the top plate 3 includes a first plate 3.1 directly opposite the back plate 2, a second plate 3.2 extending outward from one end of the first plate 3.1 toward the opposite top plate 3, and a third plate 3.3 extending from the outer end of the second plate 3.2 toward the opposite top plate 3. The length of the second plate 3.2 is set such that when the third plate 3.3 abuts against the surface of the aluminothermic mold, the first plate 3.1 is located directly below the top of the rail.

[0036] Specifically, when using arc welding for rail maintenance, the first plate 3.1 directly abuts against the rail web. When using aluminothermic welding for rail maintenance, the first plate 3.1 is located directly below the rail top, while the second plate 3.2 rests against the surface of the aluminothermic mold corresponding to the rail length direction, and the third plate 3.3 rests against the outer surface of the aluminothermic mold. At this time, by rotating the bidirectional lead screw 5, the aluminothermic mold, under pressure from the top plate 3, is clamped and fixed along the rail length direction, while the other aluminothermic mold remains tightly pressed against the abutment plate 2 throughout the entire operation, thus better maintaining the flush, tight, and sealed effect of the two aluminothermic molds.

[0037] The first plate 3.1 has a fourth plate 3.4 at its top, which is parallel to the bottom of the rail top. By setting the fourth plate 3.4, the contact surface between the fourth plate 3.4 and the bottom of the rail top is sufficiently large, which improves the stability of clamping and fixing the rail in the height direction, improves the alignment effect of the rail, and ensures the accuracy of rail maintenance.

[0038] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
