Description

An insulated rail clamp that can travel along a track Technical Field

[0001] This utility model relates to the field of rail clamping technology, and in particular to an insulated rail clamping device that can travel with the rail. Background Technology

[0002] In railways, urban rail transit, and other fields, track maintenance and repair are crucial. The connection and movement of related equipment with the tracks have always been key concerns in these processes. Currently, traditional track connection and equipment installation methods have revealed numerous shortcomings in practical applications, causing significant challenges to track maintenance and repair work.

[0003] In track maintenance and repair work, track connecting equipment is often used in conjunction with auxiliary equipment such as ladder trucks. However, the existing connection methods between track connecting equipment and auxiliary equipment such as ladder trucks are not ideal. The connection structure is simple and cannot effectively improve the overall stability of the combination. In actual use, relative swaying easily occurs between the ladder truck and the track connecting equipment, which not only affects the operation of workers but also increases safety risks, making workers face greater dangers when working at heights. At the same time, different tracks may have certain angle differences during the laying process, and traditional track connecting equipment usually does not have a clamping angle adjustment function. This means that when facing tracks with different angles, the equipment cannot fit well with the track, thus affecting the fixing effect and performance of the equipment. For example, on some curved tracks, due to the curvature of the track, ordinary rail clamps cannot adjust the clamping angle, making it difficult to firmly grip the track and prone to slippage. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an insulated rail clamp that can travel along the track. By adjusting the clamping angle of the clamping component through the adjustment component, the clamping component grips the track, the moving component enables travel along the track, and the stable component connects to the ladder car, thereby improving the gripping stability of the rail clamp, facilitating flexible movement on the track, enhancing the stability of the combination with the ladder car, and providing more reliable and efficient equipment support for track maintenance and repair work.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] As shown in Figures 1 and 2, this utility model provides an insulated rail clamp that can travel along a track, including a main housing 1. An adjustment component, a clamping component, and a moving component are respectively installed on the main housing 1. A stabilizing component is installed on one side of the main housing 1. The adjustment component is used to adjust the clamping angle of the clamping component. The clamping component is used to grip the track to prevent the rail clamp from sliding or deviating on the track. The moving component is used to make the rail clamp travel along the track, adapting to the rail clamp working at different track positions. The stabilizing component is used to connect the rail clamp to the ladder car, improving the overall stability of the rail clamp and ladder car assembly.

[0028] The main housing 1 serves as the foundational support structure for the entire rail clamp, providing a base platform for the installation of the adjustment, clamping, moving, and stabilizing components. It ensures the relative positional relationships between the components, guaranteeing the stability and reliability of the overall structure, and enabling the rail clamp to operate normally under various working conditions.

[0029] The adjustment assembly includes a spring sleeve 2, a pull rod 3, a circular plate 5, and a handle 4. The spring sleeve 2 is mounted above the main housing 1 and contains a spring 13. The spring sleeve 2 is located on the outer wall of the pull rod 3, and the bottom of the spring 13 is connected to the crossbeam of the connecting plate 14. One end of the pull rod 3 passes through the main housing 1 and connects to the crossbeam of the connecting plate 14, while the other end is rotatably connected to the circular plate 5. The handle 4 is detachably connected to one side of the circular plate 5. Its function is to adjust the clamping angle and position of the clamping assembly. When the operator operates the handle 4, the handle 4 drives the circular plate 5 to rotate, and the circular plate 5 drives the pull rod 3 to move. Due to the presence of the spring 13, it plays a buffering and resetting role during the adjustment process, making the adjustment smoother. The movement of the pull rod 3 is transmitted to the connecting plate 14, thereby realizing the adjustment of the clamping assembly.

[0030] The clamping assembly includes a connecting plate 14, a first slide rod 19, rubber fixing claws 6, and ball bolts 7. The connecting plate 14 has a horizontal H-shaped structure and is installed inside the main housing 1. An adjustment assembly is installed on its crossbeam, and the first slide rod 19 is threaded to its two ends. Two rubber fixing claws 6 are symmetrically arranged, with their horizontal ends respectively fitted onto the outer wall of the corresponding first slide rod 19. A ball bolt 7 is installed on the bottom inner side of the rubber fixing claw 6, with one end of the ball bolt 7 connected to the rubber fixing claw 6; as shown in Figure 3, the other end of the ball bolt 7 has a ball groove 18, which contains a main ball 16 and several sets of auxiliary balls 17. The main function of the clamping assembly is to grip the track and prevent the rail clamp from sliding or deviating on the track. Under the action of the adjustment assembly, the rubber fixing claw 6 can move along the first slide rod 19 to adjust the clamping position. The rubber fixing claw contacts the track, increasing the friction. The design of the ball bolt 7 allows the rubber fixing claw 6 to better adapt to the shape and angle changes of the track when gripping it. The cooperation between the main ball 16 and the auxiliary ball 17 reduces friction and improves the flexibility and stability of gripping.

[0031] The moving assembly consists of baffles 15 mounted on the bottom of the crossbeam of the connecting plate 14, a second slide rod 20, and rubber rollers 8. Two baffles 15 are symmetrically fixed to the bottom of the connecting plate 14, with the second slide rod 20 bolted to their inner sides. The rubber rollers 8 are connected to the outer surface of the second slide rod 20 and installed at the bottom center of the main housing 1. The moving assembly is used to propel the rail clamp along the track. When the rail clamp needs to be moved, the rubber rollers 8 contact and roll with the track. Limiting movement on the second slide rod 20 allows the rail clamp to move to different track positions, adapting to different working requirements.

[0032] The stabilizing assembly includes a fixing plate 9, a first screw 10, a second screw 21, a sliding sleeve 11, a buckle 12, and a limiting nut 22. The first screw 10 and the second screw 21 are arranged parallel to each other, with one end welded to the main housing 1 via the fixing plate 9. Sliding sleeves 11 are fitted onto the outer surfaces of both the first screw 10 and the second screw 21. Limiting nuts 22 are located at both ends of the sliding sleeves 11, and are threadedly connected to the screws to restrict the position of the sliding sleeves 11. A buckle 12 is welded below the sliding sleeve 11. The buckle 12 is a clamp-type structure, consisting of two sets of arc-shaped ring structures, one end of which is rotatably connected via a pivot, and the other end is connected via an adjusting bolt. The function of the stabilizing assembly is to connect the rail clamp to the ladder truck, improving the overall stability of the rail clamp and ladder truck assembly. By adjusting the limiting nut 22, the position of the sliding sleeve 11 on the screw is changed, thereby adjusting the position of the buckle 12. When in use, place the buckle 12 on the corresponding part of the ladder car, and tighten the buckle 12 by adjusting the bolt to achieve a firm connection between the rail clamp and the ladder car.

[0033] Working principle: When the insulated rail clamp is needed, firstly, operate the handle 4. The handle 4 drives the circular plate 5 to rotate, and the circular plate 5 drives the pull rod 3 to move. With the cooperation of the spring sleeve 2 and the spring 13, the pull rod 3 drives the connecting plate 14 to move. The movement of the connecting plate 14 is transmitted to the clamping assembly through the first slide rod 19. Since the first slide rod 19 is threaded to the openings at both ends of the connecting plate 14, and the horizontal ends of the two rubber fixing claws 6 are respectively sleeved on the outer wall of the corresponding first slide rod 19, when the connecting plate 14 moves, the first slide rod 19 will move accordingly, thereby driving the rubber fixing claws 6 to move.

[0034] At this time, the rubber fixing claw 6 adjusts its clamping position according to the moving direction and distance of the connecting plate 14. During the adjustment process, the ball bolt 7 installed on the inner bottom of the rubber fixing claw 6 plays an important role. One end of the ball bolt 7 is connected to the rubber fixing claw 6, and the other end has a ball groove 18 with a main ball 16 and several sets of auxiliary balls 17. When the rubber fixing claw 6 moves, the main ball 16 and auxiliary balls 17 roll in the ball groove 18, allowing the rubber fixing claw 6 to adapt more flexibly to the shape and angle changes of the track surface, ensuring a tight fit with the track, improving the stability of the grip, and reducing the friction between the rubber fixing claw 6 and the track, thus reducing the degree of wear. When the rubber fixing claw 6 moves to the appropriate position, the handle 4 is released, and the elastic force of the spring 13 will cause the pull rod 3 to return to its original position, thereby allowing the rubber fixing claw 6 to firmly grip the track and prevent the rail clamp from sliding or deviating on the track.

[0035] If it is necessary to move the rail clamp to different track positions for operation, push the rail clamp, and the moving component will start working. The outer surface of the rubber roller 8 in the moving component contacts the track. Since the rubber roller 8 is connected to the outer surface of the second slide rod 20, and the second slide rod 20 is fixed by the baffles 15 symmetrically arranged at the bottom of the connecting plate 14, when the rail clamp is pushed, the rubber roller 8 will roll on the track, and based on the limit of the second slide rod 20, it will drive the entire rail clamp to travel along the track, realizing the movement of the rail clamp to different track positions.

[0036] When it is necessary to connect the rail clamp to the ladder truck, this is achieved by adjusting the stabilizing components. First, rotate the limiting nut 22 on the first screw 10 and the second screw 21. Since the limiting nut 22 is threadedly connected to the screw, rotating the limiting nut 22 allows the sliding sleeve 11 to move on the screw. As the sliding sleeve 11 moves, the latch 12 welded below also moves accordingly, adjusting the latch 12 to the position corresponding to the connection part of the ladder truck. Then, using the clamp-like structure of the latch 12, adjust the distance between the two sets of arc-shaped clamping structures by adjusting the bolts, so that the latch 12 tightly grips the connection part of the ladder truck. In this way, the rail clamp is securely connected to the ladder truck, improving the overall stability of the rail clamp and ladder truck assembly, ensuring safety during high-altitude operations and the stability of equipment operation.

[0037] Therefore, by adopting the above-mentioned insulated rail clamp that can travel along the track, the clamping angle of the clamping component can be adjusted by adjusting the component, and the clamping component can grip the track, the moving component can achieve travel along the track, and the component can be firmly connected to the ladder car. This improves the gripping stability of the rail clamp, facilitates flexible movement on the track, enhances the stability of the combination with the ladder car, and provides more reliable and efficient equipment support for track maintenance and repair work.

[0038] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
