Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to an elastic clamping device for fixing cables in high-altitude areas to prevent freezing and cracking. Background Technology

[0002] In the complex and ever-changing natural environment of plateau regions, the fixation and protection of cables have always been crucial for the construction of infrastructure such as power and communication. Clamps are indispensable key components, and their performance directly affects the stability and safety of the cable system, making them important equipment for ensuring the stability of cable connections.

[0003] In existing technologies, high-altitude areas are subject to sudden loads such as falling snow and ice and instantaneous impacts from strong winds. Traditional rigid clamps are often unable to effectively absorb and disperse impact energy when faced with such sudden loads. In low-temperature environments, the physical properties of the cable itself change, and its brittleness increases significantly, making the cable more susceptible to damage when directly subjected to impacts. This damage is not limited to the surface but may penetrate deep into the cable, affecting its conductivity and overall structural stability, thereby shortening the cable's service life and increasing maintenance costs and safety risks. Utility Model Content

[0004] The purpose of this utility model is to provide a high-altitude cable fixing anti-freezing and cracking elastic clamp device to solve the problem mentioned in the background art that the traditional rigid clamps, due to material and design limitations, directly transmit the impact force to the cable when faced with falling ice and snow, strong winds, etc., and the cable becomes more brittle at low temperatures, making it prone to internal and external damage when subjected to impact, affecting conductivity and structural stability, and thus shortening service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plateau cable fixing anti-freezing and cracking elastic clamp device, comprising a shell body consisting of a first clamp shell and a second clamp shell rotatably connected to the first clamp shell, and a shell partition fixedly connected to the shell body, further comprising a snap-fit ​​assembly and a fixed inner plate installed on the shell body, a slider assembly installed on the fixed inner plate, a mounting seat installed on the slider assembly, a first buffer pad and a second buffer pad installed on the mounting seat, an adjustment drive assembly installed inside the shell body, and a linkage assembly installed between the adjustment drive assembly and the slider assembly, wherein the linkage assembly is connected to the output end of the adjustment drive assembly, and the first buffer pad is installed between the mounting seat and the second buffer pad; After the cable passes through the main body of the housing and the second clamp housing rotates to fit and seal with the first clamp housing, the rotation of the second clamp housing is restricted by the snap-fit ​​component. When the adjustment drive component is operated, the slider component is driven to move along the preset direction through the linkage component. When the slider component moves, it drives the mounting base away from or closer to the cable.

[0006] Based on the preferred embodiment of this technical solution, both the first buffer pad and the second buffer pad are provided with several sets of through holes, and the through holes on the first buffer pad are larger than the through holes on the second buffer pad. The through holes are all honeycomb-shaped and uniformly distributed on the first buffer pad and the second buffer pad.

[0007] According to the preferred embodiment of this technical solution, the adjustment drive assembly includes a bidirectional threaded rod rotatably connected to the fixed inner plate and a first knob fixedly connected to the bidirectional threaded rod, the first knob being used to drive the bidirectional threaded rod to rotate.

[0008] In a preferred embodiment of this technical solution, the slider assembly includes a guide rail fixedly connected to the fixed inner plate and a slider block slidably connected to the guide rail, with the mounting base fixedly mounted on the slider block.

[0009] According to the preferred embodiment of this technical solution, the linkage component includes a sliding seat slidably connected to the fixed inner plate and a first rotating rod rotatably connected between the sliding seat and the sliding block. The sliding seat is threadedly connected to the bidirectional threaded rod. When the bidirectional threaded rod rotates, the connected sliding seat moves along a preset direction. When the sliding seat moves, it pushes the sliding block to move along the preset direction through the first rotating rod.

[0010] In a preferred embodiment of this technical solution, the fixed inner plate has a limiting groove at the relative position of the sliding seat, and the sliding seat is slidably connected to the groove.

[0011] According to the preferred embodiment of this technical solution, the snap-fit ​​assembly includes a fixed bracket fixedly mounted on the first clamp housing, a connecting block fixedly mounted on the second clamp housing, a sliding rod and a pull rod slidably connected to the fixed bracket, a snap-fit ​​block fixedly connected to the sliding rod and the pull rod, and a first spring fixedly connected between the snap-fit ​​block and the fixed bracket. The snap-fit ​​block is snap-fitted onto the connecting block. The pull rod is used to drive the snap-fit ​​block to move in a preset direction. When the snap-fit ​​block is pulled away from the connecting block, the first spring is compressed. After the pull rod is sent, the snap-fit ​​block is pushed closer to the connecting block by the rebound of the first spring.

[0012] In a preferred embodiment of this technical solution, the connecting block has a slot that matches the snap-fit ​​block, and the snap-fit ​​block snaps into the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The first and second buffer pads are designed with full consideration of the characteristics of the complex environment of the plateau and the actual needs of cable fixing. They are used in conjunction with low-temperature elastic polyurethane foam substrate containing anti-aging agents and toughening agents. When encountering situations such as falling ice and snow or strong wind impacts, they can dissipate the potentially huge impact force bit by bit and evenly distribute it to all parts of the cable tower, avoiding cable damage due to uneven local stress, greatly extending the service life of the cable, and ensuring the stability and safety of cable transmission in plateau areas.

[0014] 2. The first and second buffer pads adopt a double-layer honeycomb design. Compared with the single-layer buffer pad design, the three-dimensional structure of the double-layer honeycomb structure greatly improves the compression resistance and resilience of the buffer pad. The supporting effect of the honeycomb can disperse the pressure brought by long-term clamping and cyclic impact, prevent the buffer pad from being gradually compacted due to continuous force, and always maintain good elastic deformation ability.

[0015] 3. By setting up an adjustment drive component in conjunction with a linkage component, the distance between the mounting base and the cable can be flexibly adjusted according to the cable diameter during use. There is no need to equip special clamps for different specifications of cables, which greatly reduces equipment procurement and inventory costs, while simplifying the installation and maintenance process in high-altitude outdoor environments and improving construction efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1 - Figure 8 This utility model provides an embodiment: a plateau cable fixing anti-freezing and cracking elastic clamp device, including a shell body composed of a first clamp shell 1 and a second clamp shell 4 rotatably connected to the first clamp shell 1, and a shell partition 5 fixedly connected to the shell body. It also includes a snap-fit ​​assembly and a fixed inner plate 21 installed on the shell body, a slider assembly installed on the fixed inner plate 21, a mounting seat 23 installed on the slider assembly, a first buffer pad 24 and a second buffer pad 25 installed on the mounting seat 23, an adjustment drive assembly installed in the shell body, and a linkage assembly installed between the adjustment drive assembly and the slider assembly. The linkage assembly is connected to the output end of the adjustment drive assembly, and the first buffer pad 24 is installed between the mounting seat 23 and the second buffer pad 25. After the cable passes through the main body of the outer casing and rotates to fit and seal the second clamp housing 4 with the first clamp housing 1, the rotation of the second clamp housing 4 is restricted by the snap-fit ​​component. When the adjustment drive component is operated, the slider component is driven to move along the preset direction through the linkage component. When the slider component moves, it drives the mounting base 23 away from or closer to the cable. The outer shell partition 5 is specifically made of closed-cell polyurethane foam. When in use, after the cable is passed through the outer shell body, the second clamp shell 4 is rotated to fit against the first clamp shell 1 to form a closed outer shell body. At this time, the snap-fit ​​component plays a role in restricting the rotation of the second clamp shell 4 and ensuring that the outer shell body remains closed. The adjustment drive component is operated according to the cable size. The adjustment drive component, in cooperation with the linkage component, drives the slider component to move in a preset direction. During the movement of the slider component, the mounting base 23 will move synchronously, so that the mounting base 23 gradually moves closer to or away from the cable. The first buffer pad 24 is installed between the mounting base 23 and the second buffer pad 25. As the mounting base 23 moves, the first buffer pad 24 and the second buffer pad 25 will move together with the mounting base 23 to approach the cable and fit against the cable, thereby clamping and fixing the cable. When the mounting base 23 moves away from the cable, the first buffer pad 24 and the second buffer pad 25 will also detach from the cable, releasing the clamping of the cable. Throughout the process, the outer shell partition 5 cooperates with the outer shell body to provide protection for the internal components and cables.

[0020] Please see Figure 6A further solution based on this embodiment is as follows: both the first buffer pad 24 and the second buffer pad 25 are provided with several sets of through holes, and the through holes on the first buffer pad 24 are larger than the through holes on the second buffer pad 25. The through holes are all honeycomb-shaped and evenly distributed on the first buffer pad 24 and the second buffer pad 25. The closed-cell foam between the first buffer pad 24 and the second buffer pad 25 is made of low-temperature elastic polyurethane foam, with added anti-aging agents and toughening agents to enhance low-temperature stability and elasticity. The honeycomb-shaped through holes give the buffer pad itself good elastic deformation ability. The differentiated design of large and small through holes achieves graded buffering when the buffer pad comes into contact with the cable. When facing situations such as falling ice and snow or strong winds, it disperses the pressure on the cable. The honeycomb-shaped and evenly distributed through holes can improve the structural stability of the buffer pad and avoid damage caused by uneven local stress. The large and small through holes, together with the elastic recovery ability of each layer of buffer pad, can maintain good flexibility even in the low-temperature environment of high altitude.

[0021] Please see Figure 1 - Figure 5 A further solution based on this embodiment is as follows: the adjustment drive assembly includes a bidirectional threaded rod 26 rotatably connected to the fixed inner plate 21 and a first knob 27 fixedly connected to the bidirectional threaded rod 26. The first knob 27 is used to drive the bidirectional threaded rod 26 to rotate. Rotating the first knob 27 can directly drive the bidirectional threaded rod 26 to rotate. The bidirectional threaded rod 26 converts the rotational motion into the linear motion of the linkage assembly through thread transmission, providing power for the movement of the slider assembly. The bidirectional threaded rod 26 has high transmission accuracy and can accurately control the movement distance of the linkage assembly, thereby realizing fine adjustment of the fit between the mounting base 23 and the cable, and adapting to high-altitude cables of different diameters.

[0022] Please see Figure 1 - Figure 5 A further solution based on this embodiment is as follows: the slider assembly includes a guide rail 210 fixedly connected to the fixed inner plate 21 and a slider block 22 slidably connected to the guide rail 210. The mounting base 23 is fixedly installed on the slider block 22. The guide rail 210 provides a fixed movement trajectory for the slider block 22. Under the drive of the linkage component, the slider block 22 slides smoothly along the guide rail 210, thereby driving the mounting base 23 above to move synchronously. The guide rail 210 can effectively limit the movement direction of the slider block 22, avoid deviation that causes the mounting base 23 to misalign with the cable, and ensure fixing accuracy.

[0023] Please see Figure 3 - Figure 5A further solution based on this embodiment is as follows: The linkage component includes a sliding seat 28 slidably connected to the fixed inner plate 21 and a first rotating rod 29 rotatably connected between the sliding seat 28 and the sliding block 22. The sliding seat 28 is threadedly connected to a bidirectional threaded rod 26. When the bidirectional threaded rod 26 rotates, the connected sliding seat 28 moves in a preset direction. When the sliding seat 28 moves, it pushes the sliding block 22 to move in a preset direction through the first rotating rod 29. When the bidirectional threaded rod 26 rotates, it drives the sliding seat 28 to move linearly through the thread. The movement of the sliding seat 28 causes the first rotating rod 29 to change angle, thereby transmitting power to the sliding block 22 and pushing the sliding block 22 to move along the guide rail 210. The rotational connection design of the first rotating rod 29 can adapt to the positional changes between the sliding seat 28 and the two connected sliding blocks 22, ensuring the synchronicity of the movement of the two inner sliding blocks 22. After the adjusted first buffer pad 24 and second buffer pad 25 approach the cable, they elastically clamp the cable and limit the position of the cable.

[0024] Please see Figure 3 - Figure 5 A further solution based on this embodiment is as follows: the fixed inner plate 21 has a limiting groove at the relative position of the sliding seat 28. The sliding seat 28 is slidably connected to the groove. The groove forms a longitudinal limit on the sliding seat 28, guiding the sliding seat 28 to move only along the extension direction of the groove, avoiding lateral deviation or shaking of the sliding seat 28 during movement. The limiting groove can further improve the movement accuracy of the sliding seat 28, ensure the transmission accuracy of the linkage component, ensure the stability of the overall structure of the device, and avoid loosening of the cable fixation due to the deviation of the sliding seat 28.

[0025] Please see Figure 7 - Figure 8A further embodiment of this solution is as follows: the snap-fit ​​assembly includes a fixed bracket 31 fixedly mounted on the first clamp housing 1, a connecting block 32 fixedly mounted on the second clamp housing 4, a sliding rod 33 and a pull rod 36 slidably connected to the fixed bracket 31, a snap-fit ​​block 34 fixedly connected to the sliding rod 33 and the pull rod 36, and a first spring 35 fixedly connected between the snap-fit ​​block 34 and the fixed bracket 31. The snap-fit ​​block 34 is snap-fitted onto the connecting block 32. The pull rod 36 is used to drive the snap-fit ​​block 34 to move in a preset direction. When the snap-fit ​​block 34 is pulled away from the connecting block 32, the first spring 35 is compressed and the pull rod 36 is released. Then, the first spring 35 rebounds and pushes the snap-fit ​​block 34 close to the connecting block 32. After the two clamp housings are closed, the rebound force of the first spring 35 pushes the snap-fit ​​block 34 to engage with the connecting block 32, thus locking the main body of the housing. Pulling the lever 36 can cause the snap-fit ​​block 34 to disengage from the connecting block 32, releasing the lock and opening the housing. The snap-fit ​​assembly achieves locking through the automatic rebound of the spring, making the operation convenient and efficient, and suitable for the needs of rapid installation and maintenance in high-altitude outdoor environments. The elasticity of the first spring 35 makes the snap-fit ​​block 34 and the connecting block 32 engage more tightly, providing good shock resistance and resisting external vibrations such as strong winds at high altitudes, preventing the housing from opening accidentally.

[0026] Please see Figure 7 - Figure 8 A further solution based on this embodiment is as follows: the connecting block 32 is provided with a slot that is adapted to the snap-fit ​​block 34. The snap-fit ​​block 34 is snap-fitted into the slot. The shape and size of the slot and the snap-fit ​​block 34 are precisely matched, so that the snap-fit ​​block 34 can be precisely embedded in the slot to form a firm snap-fit ​​fit, which restricts the relative rotation of the two clamp housings. The adapted slot design can improve the sealing and firmness of the snap-fit, prevent the snap-fit ​​block 34 from falling off during use, ensure the sealing of the housing body, and reduce the corrosion of internal components and cables by external low temperature, wind and snow.

[0027] Other embodiments: The outer shell layer 5 can also adopt other structures in the prior art, with polytetrafluoroethylene (PTFE) film replacing closed-cell polyurethane foam material; the advantages are that it has a very wide range of high and low temperature resistance (-200℃~260℃), which is fully adapted to the extreme temperature of high altitude; the surface is hydrophobic and oleophobic, which can prevent ice, snow and water vapor from adhering and penetrating, and avoid internal components from getting damp and rusting; it is abrasion resistant and anti-aging, and will not lose its thermal insulation and protection effect due to wind erosion and wear after long-term use.

[0028] Working principle: This high-altitude cable fixing and anti-freezing elastic clamp device uses the outer shell and outer shell partition 5 as the basic protective structure. It is equipped with a snap-fit ​​component, a fixing inner plate 21, a slider component, a mounting base 23, a first buffer pad 24, a second buffer pad 25, an adjustment drive component, and a linkage component to achieve precise clamping and protection of the cable. In use, the cable to be fixed is first passed through the outer shell, which is composed of the first clamp shell 1 and the second clamp shell 4. At this time, the pull rod 36 is pulled to move the snap-fit ​​block 34 away from the connecting block 32. Then, the second clamp shell 4 is rotated so that it fits against the first clamp shell 1 to form a closed outer shell structure. After the pull rod 36 is released, the snap-fit ​​block 34 cooperates with the connecting block 32 on the second clamp shell 4 under the action of the first spring 35. The snap-fit ​​block 34 is precisely embedded in the slot of the connecting block 32, which restricts the rotation of the second clamp shell 4 and ensures that the outer shell remains closed. The outer shell partition 5 cooperates with the outer shell to provide basic protection for the internal components and cables. Next, according to the specific dimensions of the cable to be fixed, the clamping accuracy is adjusted by manipulating the adjustment drive assembly. The first knob 27 of the adjustment drive assembly is rotated, and the first knob 27 directly drives the bidirectional threaded rod 26 to rotate. The bidirectional threaded rod 26 converts the rotational motion into linear power through thread transmission and transmits it to the linkage assembly. The sliding seat 28 of the linkage assembly is threadedly engaged with the bidirectional threaded rod 26. When the bidirectional threaded rod 26 rotates, the sliding seat 28 moves linearly in a preset direction along the slide groove on the fixed inner plate 21. During the movement of the sliding seat 28, the first rotating rod 29 connected to it changes angle. The first rotating rod 29 transmits power to the sliding block 22 of the slider assembly, pushing the sliding block 22 to slide smoothly along the guide rail 210 on the fixed inner plate 21. The slider 22 of the slider assembly is fixedly connected to the mounting base 23. When the slider 22 moves along the guide rail 210, it synchronously drives the mounting base 23 to move closer to or away from the cable. Since the first buffer pad 24 is installed between the mounting base 23 and the second buffer pad 25, when the mounting base 23 moves, it will drive the first buffer pad 24 and the second buffer pad 25 to move together. When the mounting base 23 gradually approaches the cable, the first buffer pad 24 and the second buffer pad 25 will then come into contact with the cable surface, achieving elastic clamping and fixing of the cable. If it is necessary to release the clamping, the drive assembly is adjusted by reversing the operation. The bidirectional threaded rod 26 drives the sliding seat 28 to move in the opposite direction. The first rotating rod 29 pulls the sliding block 22 away from the cable along the guide rail 210. The mounting seat 23 simultaneously drives the first buffer pad 24 and the second buffer pad 25 to detach from the cable, completing the clamping release operation. After clamping, the honeycomb through holes on the first buffer pad 24 and the second buffer pad 25 cooperate with each other. The differentiated design of large and small through holes achieves graded buffering. Combined with the low-temperature elastic polyurethane foam filled inside, it always stays in contact with the cable in the clamping state, ensuring the stability and reliability of clamping.
