Description

Technical Field

[0001] This utility model relates to the field of clamps for replacing insulators, and in particular to a quick replacement clamp for insulators of transmission lines. Background Technology

[0002] Transmission line insulators are devices used in power systems, primarily to support conductors and prevent electrical short circuits between the conductors and the ground or other conductors. Through their high resistance characteristics, they can withstand voltage on the line, ensuring that current is not conducted through the support structure, thus maintaining the safe operation of the power system. Quick-change clips are tools used for quickly replacing insulators or other line components, reducing power outage time and maintenance costs. The connection between the two lies in the fact that quick-change clips significantly improve the efficiency of insulator replacement, enabling rapid and safe completion of work during maintenance and replacement, thereby ensuring the normal operation and efficient maintenance of transmission lines.

[0003] In existing technologies, the working principle of quick-change clamps for transmission line insulators is mainly based on the rapid locking and unlocking of insulators through mechanical devices. These clamps are typically designed to quickly and safely remove and replace damaged or aged insulators without requiring large-scale power outages. During operation, workers contact the insulator using the clamps installed on the transmission line and lock or release it using specific operating methods (such as hydraulic, spring, or electric control). The quick-change clamps provide sufficient fixing force to ensure that the insulators do not fall off due to external forces during replacement, while also reducing the complexity of manual operation and improving work efficiency and safety.

[0004] In existing technologies, some transmission line insulator quick-change clips use traditional bolt fixing methods. While this design ensures a secure fixation, it increases the burden of working at heights. When working at heights, operators need to use tools to tighten and loosen the bolts, which not only requires a considerable amount of time and high precision but also increases labor intensity and operational difficulty. Especially in harsh weather and complex working environments, it can also pose safety hazards. Therefore, the quick-change clip for transmission line insulators is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-change clip for transmission line insulators, which aims to improve the problem that some quick-change clips for transmission line insulators in the prior art increase the burden of high-altitude operations due to the use of traditional bolts for fixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick-change clamp for transmission line insulators, comprising two lower clamping blocks and two upper clamping blocks, the exterior of the two upper clamping blocks being rotatably connected to the interior of the two lower clamping blocks, a micro-adjustment mechanism being fixedly connected to the interior of the lower clamping blocks and the interior of the upper clamping blocks, a connecting rod being rotatably connected to the left and right sides of the lower clamping blocks, a suspension hook being fixedly connected to the exterior of the connecting rod, and a quick-connection mechanism being fixedly connected to the interior of the upper clamping blocks;

[0007] The quick-connect mechanism includes two locking blocks, the bottoms of the two locking blocks are fixedly connected to the tops of the two lower clamping blocks, two sliding locking blocks are slidably connected inside the two upper clamping blocks, multiple adjusting springs are fixedly connected to the opposite sides of the two sliding locking blocks, an unlocking component is slidably connected inside the upper clamping blocks, a rotating block is rotatably connected to the tops of the two sliding locking blocks, and the bottom of the rotating block is rotatably connected inside the upper clamping blocks.

[0008] As a further description of the above technical solution: the micro-adjustment mechanism includes multiple rubber pads, the exterior of the multiple rubber pads is fixedly connected to the interior of the lower clamping block and the interior of the upper clamping block, and multiple anti-slip teeth are fixedly connected to the interior of the multiple rubber pads, with the adjacent side of the multiple anti-slip teeth in contact with the exterior of the insulator;

[0009] As a further description of the above technical solution: the unlocking component includes a reset spring, one end of which is fixedly connected to the inside of the upper clamping block, and the other end of which is fixedly connected to an unlocking block. The unlocking block is slidably connected to the outside of the upper clamping block and to the inside of the locking block.

[0010] As a further description of the above technical solution: the upper clamping block has a sliding groove inside, and the two sliding locking blocks are externally slidably connected inside the sliding groove;

[0011] As a further description of the above technical solution: the top of the unlocking block is provided with a squeezing block, and the outside of the squeezing block is in contact with the adjacent side of the two rotating blocks;

[0012] As a further description of the above technical solution: both the lower clamping block and the upper clamping block have a fixing groove inside, and the rubber pad is fixedly connected to the inside of the fixing groove.

[0013] As a further description of the above technical solution: a pushing block is fixedly connected to the top of the squeezing block, the pushing block is in contact with the user, an adjustment groove is provided inside the upper clamping block, and the outside of the pushing block is slidably connected to the inside of the adjustment groove;

[0014] As a further description of the above technical solution: a fixing block is fixedly connected to one side of the two sliding locking blocks, and the outside of the fixing block is slidably connected to the inside of the locking block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the insulator is clamped by the cooperation of the lower clamping block and the upper clamping block. Pressing the unlocking block squeezes the return spring and drives the two rotating blocks to rotate, thereby pushing the sliding lock block to slide. After the upper clamping block is aligned with the locking block, the unlocking block is released, and the return spring and the adjusting spring push the sliding lock block and the unlocking block to reset, thereby completing the clamping of the locking block. Furthermore, because the two sliding lock blocks and the unlocking block clamp the locking block in three directions, the connection between the lower clamping block and the upper clamping block is strengthened, while reducing the cumbersome use of bolts for fixing when using traditional insulator replacement clamps.

[0017] 2. In this utility model, the rubber pads and anti-slip teeth fixed inside the lower and upper clamping blocks cooperate with each other, allowing the device to be finely adjusted according to insulators of different sizes. Furthermore, the anti-slip teeth are in close contact with the insulators, thereby enhancing the friction between the anti-slip teeth and the insulators and thus enhancing the stability of the device.

[0025] 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.

[0026] Reference Figure 1 , Figure 4 , Figure 5 This utility model provides an embodiment of a quick-change clamp for transmission line insulators, comprising two lower clamping blocks 1 and two upper clamping blocks 2. The lower clamping blocks 1 are the basic components of the entire device, mainly serving a supporting and fixing function. The upper clamping blocks 2 are used to directly contact the insulator and are fixed through a clamping mechanism. The exterior of each upper clamping block 2 is rotatably connected to the interior of each lower clamping block 1. A micro-adjustment mechanism is fixedly connected inside both the lower clamping blocks 1 and the upper clamping blocks 2. This micro-adjustment mechanism is used to finely adjust the clamping pressure and position of the clamping blocks, ensuring precise contact between the clamp and the insulator. Connecting rods 5 are rotatably connected to the left and right sides of each lower clamping block 1, connecting the left and right sides of the lower clamping block 1. The connecting rods 5 are designed to withstand a certain tension to ensure stable operation of the clamp during use. A suspension hook 6 is fixedly connected to the exterior of the connecting rod 5, used to suspend the clamp. The suspension hook 6 allows the clamp to be easily suspended on the transmission line, facilitating operation by personnel working at height. A quick-connect mechanism is fixedly connected inside each upper clamping block 2.

[0027] The quick-connect mechanism includes two locking blocks 7, which are fixed to the top of the lower clamping block 1 and serve to lock the upper clamping block 2. The bottom of the locking blocks 7 is fixedly connected to the lower clamping block 1, ensuring the stability of the clamp and preventing loosening during operation. The bottoms of the two locking blocks 7 are fixedly connected to the tops of the two lower clamping blocks 1. Two sliding locking blocks 9 are slidably connected inside the two upper clamping blocks 2. The sliding locking blocks 9 are located inside the upper clamping blocks 2 and can slide during locking and unlocking. Multiple adjusting springs 8 are fixedly connected to the opposite sides of the two sliding locking blocks 9. The adjusting springs 8 are positioned between the sliding locking blocks 9 and the upper clamping blocks 2, providing appropriate elasticity to allow the sliding locking blocks 9 to slide smoothly during operation, facilitating locking and unlocking. An unlocking component is slidably connected inside the upper clamping blocks 2, and a rotating mechanism is rotatably connected to the tops of the two sliding locking blocks 9. Block 10, the rotating block 10 is used to realize the rotation action of the locking mechanism. By rotating the rotating block 10, the upper clamping block 2 can be unlocked or locked. The bottom of the rotating block 10 is rotatably connected to the inside of the upper clamping block 2. The upper clamping block 2 has a sliding groove inside, which is used to accommodate the sliding lock block 9, ensuring that the lock block can slide smoothly during the adjustment process. The outside of the two sliding lock blocks 9 is slidably connected to the inside of the sliding groove. A fixing block is fixedly connected to the adjacent side of the two sliding lock blocks 9. The fixing block is fixedly connected to the adjacent side of the sliding lock block 9. The sliding block is connected to the locking block 7 to ensure that the clamp is stable and does not shift during the clamping process. The outside of the fixing block is slidably connected to the inside of the locking block 7.

[0028] The unlocking assembly includes a return spring 11, one end of which is fixedly connected to the inside of the upper clamping block 2, and the other end of which is fixedly connected to an unlocking block 12. The unlocking block 12 can push the locking system of the upper clamping block 2 when needed. The design of the squeezing block and the pushing block ensures that the operator can easily and quickly unlock and lock the clamp, and complete the work quickly. The outside of the unlocking block 12 is slidably connected to the inside of the upper clamping block 2, and the outside of the unlocking block 12 is slidably connected to the inside of the locking block 7. The top of the unlocking block 12 is provided with a squeezing block, the outside of which is in contact with the adjacent side of the two rotating blocks 10. The top of the squeezing block is fixedly connected to a pushing block, which is used to adjust the state of the locking mechanism to ensure that the locking and unlocking process can proceed smoothly. The pushing block is in contact with the user. An adjustment groove is opened inside the upper clamping block 2 to accommodate the pushing block. The outside of the pushing block is slidably connected to the inside of the adjustment groove.

[0029] Reference Figures 2 to 4The micro-adjustment mechanism includes multiple rubber pads 3, which are fixed inside the lower clamping block 1 and the upper clamping block 2 to increase friction and reduce potential damage to the insulator from metal-to-metal contact. The external and internal connection design of the rubber pads 3 ensures stable fixation. The external connections of the multiple rubber pads 3 are fixedly connected to the interiors of the lower clamping block 1 and the upper clamping block 2, while the internal connections of the multiple rubber pads 3 include multiple anti-slip teeth 4. These anti-slip teeth 4, designed inside the rubber pads 3, effectively increase clamping force and prevent slippage between the clamp and the insulator. The anti-slip teeth 4 provide additional friction during clamping, ensuring more stable clamping. The adjacent sides of the multiple anti-slip teeth 4 contact the exterior of the insulator. Fixing grooves are provided inside both the lower clamping block 1 and the upper clamping block 2, and the external connections of the rubber pads 3 are fixedly connected inside these grooves.

[0030] Working principle: The insulator is clamped by the cooperation of the lower clamping block 1 and the upper clamping block 2. Pressing the unlocking block 12 squeezes the return spring 11 and drives the two rotating blocks 10 to rotate, thereby pushing the sliding locking block 9 to slide. After the upper clamping block 2 is aligned with the locking block 7, the unlocking block 12 is released. The return spring 11 and the adjusting spring 8 push the sliding locking block 9 and the unlocking block 12 to reset, thus completing the clamping of the locking block 7. Furthermore, the three-way clamping of the locking block 7 by the two sliding locking blocks 9 and the unlocking block 12 enhances the stability of the connection between the lower clamping block 1 and the upper clamping block 2, while reducing the cumbersome use of bolts for fixing when using traditional insulator replacement clamps.

[0031] The two connecting rods 5 located between the two lower clamping blocks 1 ensure the stability between the two lower clamping blocks 1, thereby ensuring the stability of the insulator during the replacement process. At the same time, the suspension hooks 6 fixed to the outside of the connecting rods 5 facilitate the transportation of the connecting rods 5.

[0032] The rubber pads 3 and anti-slip teeth 4 fixed inside the lower clamping block 1 and the upper clamping block 2 cooperate with each other, so that the device can be finely adjusted according to insulators of different sizes. The anti-slip teeth 4 fits tightly with the insulator, thereby enhancing the friction between the anti-slip teeth 4 and the insulator, and thus enhancing the stability of the device.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
