Description

Technical Field

[0001] This utility model relates to the field of rail transit power supply assembly technology, and in particular to a railway contact wire clamp structure. Background Technology

[0002] With the rapid expansion of the high-speed railway network, the construction of the overhead contact line requires precise positioning and reliable fixing of the flexible suspension conductors, which necessitates the use of overhead contact line clamp structures. In actual use, similar contact wire clamp structures still have many defects, such as: traditional contact wire clamp structures have the risk of dynamic loosening, and the continuous vibration generated by the train running at high speed can easily cause the bolts to gradually loosen. At the same time, the traditional contact wire clamp structure relies on experience-based installation methods, which cannot guarantee the levelness and tension uniformity of the contact wire. Therefore, it is necessary to design a railway contact wire clamp structure. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a railway contact wire clamp structure.

[0004] This utility model is achieved using the following technical solution: a railway contact wire clamp structure, including an installation assembly, the installation assembly including a mounting base, a bidirectional threaded rod rotatably connected inside the mounting base, a first lateral connecting plate and a second lateral connecting plate provided on both sides of the bidirectional threaded rod, a first gripping disc fixedly connected to the outer surface of the bidirectional threaded rod, and further including: A limiting assembly, the limiting assembly including a movable seat that is threadedly connected to the outer surface of a bidirectional threaded rod through a mounting threaded hole, and a clamping seat that matches a fixed seat is provided at the bottom of the movable seat; The fixing component includes a limiting frame fixedly connected to the inside of the clamping seat via a mounting plate, and a fixing block is threadedly connected to the inside of the limiting frame via an adjusting rod.

[0005] As a further improvement to the above solution, a fixing seat is fixedly connected to the bottom of the mounting base, and a first anti-slip block is fixedly connected to both sides of the inner wall of the fixing seat.

[0006] The above technical solution, through the composite design of a rigid base and an elastic friction layer, enables stable support of the foundation bearing surface.

[0007] As a further improvement to the above solution, the movable seat has an internal mounting threaded hole, which is threadedly connected to the outer surface of the bidirectional threaded rod.

[0008] Through the above technical solution, the operation of the precision pitch fit structure leads to an improvement in linear displacement accuracy.

[0009] As a further improvement to the above solution, a clamping seat is fixedly connected to the bottom of the movable seat, and a second anti-slip block is fixedly connected to the inner wall of the clamping seat, the second anti-slip block matching the first anti-slip block.

[0010] Through the above technical solution, the spatial construction of a dual-mode friction field drives the generation of full-circumferential anti-loosening capability. The synergistic effect of the left-right symmetrical normal pressure and the rough surface significantly enhances the vibration resistance performance.

[0011] As a further improvement to the above solution, an installation plate is fixedly connected to the inner wall of the clamping seat, a connecting frame is fixedly connected to the outer surface of the installation plate, and a limit frame is fixedly connected to the bottom of the installation plate.

[0012] As a further improvement to the above solution, the limiting frame and the connecting frame are internally threaded with an adjusting rod, and a second grip is fixedly connected to one side of the outer surface of the adjusting rod.

[0013] As a further improvement to the above solution, a fixing block is fixedly connected to the side of the outer surface of the adjusting rod away from the second grip, and the fixing block is disposed on the inner wall of the clamping seat.

[0014] The above technical solution, through the operation of the point-to-point pressure mechanism, drives the generation of local stress concentration effect.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a mechanism where a worker grips a first handgrip to drive a bidirectional threaded rod to rotate. This rotation causes the symmetrically distributed threaded grooves on the rod's surface to engage with the moving seats. This design allows the two moving seats to move synchronously towards each other along the axis under the constraint of the mounting threaded holes, thereby precisely adjusting the distance between the clamping seat and the fixed seat. This mechanical linkage mechanism achieves the initial clamping and fixing of the contact wire. At the same time, the first anti-slip block adheres to the upper surface of the contact wire to form an initial friction barrier, effectively preventing slippage. Ultimately, this ensures that the contact wire is stably positioned in the preset installation position, providing a reliable foundation for subsequent processes.

[0016] This invention utilizes a structure that rotates the adjusting rod by gripping the second gripping disc. This causes the end fixing block to vertically penetrate the reserved channel of the clamping seat and abut against the lower surface of the contact wire. During this process, the second anti-slip block works in conjunction with the pre-set groove on the inner wall of the clamping seat to construct a bidirectional clamping system. This composite locking structure completely constrains the contact wire within the closed space formed by the fixing seat and the clamping seat. Combined with the precise control characteristics of the mechanical linkage design, it significantly improves the positioning stability of the contact wire and fundamentally eliminates the risk of loosening caused by vibration or external impact, thus comprehensively ensuring the operational reliability of the railway power supply system.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example: Please combine Figure 1-4 This embodiment of a railway contact wire clamp structure includes an installation assembly 1, which includes a mounting base 101. A bidirectional threaded rod 104 is rotatably connected inside the mounting base 101. A first lateral connecting plate 102 and a second lateral connecting plate 103 are provided on both sides of the bidirectional threaded rod 104. A first gripping disc 105 is fixedly connected to the outer surface of the bidirectional threaded rod 104. The structure also includes: Limiting component 2 includes a movable seat 201 that is threadedly connected to the outer surface of the bidirectional threaded rod 104 through a mounting threaded hole 202. The bottom of the movable seat 201 is provided with a clamping seat 203 that matches the fixed seat 106. The fixing component 3 includes a limiting frame 303 that is fixedly connected to the inside of the clamping seat 203 via a mounting plate 301. A fixing block 306 is threadedly connected to the inside of the limiting frame 303 via an adjusting rod 305.

[0021] The bottom of the mounting base 101 is fixedly connected to a fixing base 106, and the two sides of the inner wall of the fixing base 106 are fixedly connected to a first anti-slip block 107.

[0022] The movable base 201 has a mounting threaded hole 202 inside, which is threaded to the outer surface of the bidirectional threaded rod 104.

[0023] The bottom of the movable seat 201 is fixedly connected to a clamping seat 203, and the inner wall of the clamping seat 203 is fixedly connected to a second anti-slip block 204, which is matched with the first anti-slip block 107.

[0024] Since the surface of the bidirectional threaded rod 104 is provided with symmetrically distributed threaded grooves, the threads on both sides of the rod are respectively engaged with the movable seats 201. The movable seats 201 are fixedly connected to the clamping seats 203 through the mounting threaded holes 202. When the bidirectional threaded rod 104 rotates clockwise or counterclockwise, the two movable seats 201 are driven by the thread and move synchronously towards each other along the axis, thereby precisely adjusting the distance between the clamping seats 203 and the fixed seats 106.

[0025] An installation plate 301 is fixedly connected to the inner wall of the clamping seat 203, a connecting frame 302 is fixedly connected to the outer surface of the installation plate 301, and a limit frame 303 is fixedly connected to the bottom of the installation plate 301.

[0026] The limiting frame 303 and the connecting frame 302 are internally threaded with an adjusting rod 305, and a second grip plate 304 is fixedly connected to one side of the outer surface of the adjusting rod 305.

[0027] A fixing block 306 is fixedly connected to the side of the outer surface of the adjusting rod 305 away from the second grip 304. The fixing block 306 is located on the inner wall of the clamping seat 203.

[0028] As the adjusting rod 305 rotates, the fixing block 306 fixed at its end moves vertically downward and penetrates the reserved channel inside the clamping seat 203, directly contacting the lower surface of the contact wire. At this time, the second anti-slip block 204 is located in the preset groove on the inner wall of the clamping seat 203, and together with the fixing block 306, it forms a bidirectional clamping system to ensure that the contact wire is firmly constrained in the closed space formed by the fixing seat 106 and the clamping seat 203.

[0029] The implementation principle of a railway contact wire clamp structure in this application embodiment is as follows: By placing the railway contact wire between the fixed seat 106 and the clamping seat 203, the operator holds the first grip plate 105 and rotates it. This operation drives the bidirectional threaded rod 104 to rotate within the limiting frame formed by the mounting seat 101, the first lateral connecting plate 102 and the second lateral connecting plate 103. Since the surface of the bidirectional threaded rod 104 is provided with symmetrically distributed threaded grooves, the threads on both sides of the rod are respectively engaged with the moving seat 201. The moving seat 201 is fixed to the clamping seat 203 through the mounting threaded hole 202. When the bidirectional threaded rod 104 rotates clockwise or counterclockwise, the two moving seats 201 move synchronously towards each other along the axis under the action of the threaded driving force, thereby accurately adjusting the distance between the clamping seat 203 and the fixed seat 106, and realizing the initial clamping and fixing of the contact wire. During this process, the first anti-slip block 107 is attached to the upper surface of the contact wire to provide initial friction and prevent slippage. After initial clamping, the operator continues to hold the second grip 304 to drive the adjusting rod 305 to rotate. The adjusting rod 305 passes through the limiting frame 303 and forms an axial limiting fit with the connecting frame 302. As the adjusting rod 305 rotates, the fixing block 306 fixed at its end moves vertically downward and penetrates the reserved channel inside the clamping seat 203, directly contacting the lower surface of the contact wire. At this time, the second anti-slip block 204 is located in the preset groove on the inner wall of the clamping seat 203, forming a two-way clamping system with the fixing block 306, ensuring that the contact wire is firmly constrained in the closed space formed by the fixing seat 106 and the clamping seat 203. The entire adjustment process is precisely controlled through mechanical linkage design, which not only ensures the positioning stability of the contact wire, but also avoids the risk of loosening caused by vibration or external force.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
