[0001] This utility model belongs to the field of power transmission line hardware installation technology, specifically relating to an auxiliary positioning device for high-altitude installation of power transmission line hardware. Background Technology
[0002] Auxiliary positioning equipment for high-altitude installation of power transmission line fittings is typically used to ensure the safety, accuracy, and efficiency of high-altitude work.
[0003] Windproof clamps are hardware used to fix and protect conductors in power transmission lines, especially in windy or severe weather conditions. Their design aims to prevent conductors from swaying or shifting due to wind, ensuring the stability and safety of the power supply line. Existing high-altitude installation auxiliary positioning equipment for power transmission line hardware has the following drawbacks: During installation, the cable is typically fixed to the clamp with bolts first, and then the clamp is fixed to the top of the insulator. This method cannot simultaneously fix the cable to the outside of the insulator, significantly reducing the efficiency of auxiliary positioning during installation. Therefore, a new high-altitude installation auxiliary positioning device for power transmission line hardware is needed. Utility Model Content
[0004] The purpose of this utility model is to provide an auxiliary positioning device for high-altitude installation of power transmission line fittings, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-altitude installation auxiliary positioning device for transmission line fittings includes a collar and two symmetrically arranged clamping seats. Two symmetrically arranged protrusions are fixed to the top of the collar. A V-shaped groove is formed in the middle of the top of each protrusion. A pressure block is provided above each V-shaped groove. The two pressure blocks are fixedly connected by a connecting rod. An inverted V-shaped groove is formed in the middle of the bottom of each pressure block. Two symmetrically arranged guide rods are fixed to the bottom of the left pressure block. Guide rods and hand-tightening bolts are respectively provided on both sides of the middle of the bottom of the right pressure block. The top of the guide rod is fixed to the bottom of the right pressure block. The hand-tightening bolt is threaded into a screw hole on the collar and is also rotatably connected to the right pressure block. The guide rods are movably inserted into guide holes on the collar. The outer arc walls of the two pressure blocks, facing away from each other, are connected to the outer arc wall of the clamping seat on the same side via a driving synchronization component.
[0007] Preferably, the driving synchronization assembly includes a U-shaped movable rod fixedly connected to the outer arc wall of the clamping seat, the U-shaped movable rod being movably inserted into the collar, and the inner side wall of the U-shaped movable rod being fixedly connected to the inner wall of the collar by an S-shaped spring piece.
[0008] Preferably, the U-shaped movable rod is movably sleeved on the outside of two symmetrically arranged inverted L-shaped pressure rods, and the bottom end of each inverted L-shaped pressure rod is provided with a first inclined surface.
[0009] Preferably, each of the U-shaped movable rods is provided with a groove that mates with the inverted L-shaped pressing rod, and the inner wall of the groove is provided with a second inclined surface parallel to the first inclined surface.
[0010] Preferably, the cross-sectional width of the groove is equal to the cross-sectional width of the bottom end of the inverted L-shaped pressure rod.
[0011] Preferably, rubber pads are fixed to the inner arc walls of both clamping seats.
[0012] Compared with the prior art, the high-altitude installation auxiliary positioning equipment for transmission line fittings provided by this utility model has at least the following beneficial effects:
[0013] When using the high-altitude installation auxiliary positioning device for transmission line fittings of this utility model, the cable is first placed into the groove at the top of the insulator, and the guide rods at the bottom of the two pressure blocks are inserted into the guide holes on the collar. Then, by rotating the hand-tightening bolt, the hand-tightening bolt spirals into the screw hole on the collar, so that the inverted V-shaped pressure grooves at the bottom of the two pressure blocks can clamp the cable in the V-shaped grooves to achieve positioning. At the same time, the first inclined surface at the bottom of the inverted L-shaped pressure rod moves down to press against the second inclined surface in the groove on the U-shaped movable rod, causing the two U-shaped movable rods to move towards each other, and the two clamping seats clamp and fix them on the outside of the insulator. This achieves cable fixation and simultaneously allows the collar to be linked and fixed on the outside of the insulator, greatly improving the efficiency of high-altitude installation auxiliary positioning. In addition, the height of the two pressure blocks can be adjusted according to the diameter of the installed cable, thus meeting the installation requirements for cables of different diameters.

Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0022] Example
[0023] Windproof clamps are hardware used to fix and protect conductors in power transmission lines, especially in windy or severe weather conditions. Their design purpose is to prevent conductors from swaying or shifting due to wind force, ensuring the stability and safety of power supply lines. Existing high-altitude installation auxiliary positioning equipment for power transmission line hardware has the following disadvantages during use: During installation, the cable 5 is usually fixed to the clamp with bolts first, and then the clamp is fixed to the top of the insulator 4. It is impossible to fix the cable 5 at the same time as simultaneously fixing it to the outside of the insulator 4, which greatly reduces the efficiency of installation auxiliary positioning.
[0024] For this purpose, please refer to Figure 1-3This utility model provides an auxiliary positioning device for high-altitude installation of transmission line fittings, comprising: a collar 1 and two symmetrically arranged clamping seats 2. Two symmetrically arranged protrusions 11 are fixedly connected to the top of the collar 1. A V-shaped groove 12 is formed in the middle of the top of each of the two protrusions 11. A pressure block 13 is provided above each V-shaped groove 12. The two pressure blocks 13 are fixedly connected by a connecting rod 131. An inverted V-shaped pressure groove is formed in the middle of the bottom end of each pressure block 13. Two symmetrically arranged guides are fixedly connected to the bottom end of the left pressure block 13. The rod 14 and the pressure block 13 on the right side are respectively provided with guide rods 14 and hand-tightening bolts 15 on both sides of the bottom middle part. The top end of the guide rod 14 is fixed to the bottom end of the pressure block 13 on the right side. The hand-tightening bolt 15 is threaded into the screw hole 151 opened on the collar 1. The hand-tightening bolt 15 is also rotatably connected to the pressure block 13 on the right side. The guide rods 14 are movably inserted into the guide holes 141 opened on the collar 1. The outer arc walls of the two pressure blocks 13 that are opposite to each other are connected to the outer arc wall of the clamping seat 2 on the same side through the driving synchronization component 3.
[0025] The top of the insulator 4 has a groove to facilitate the insertion of the cable 5.
[0026] Further as Figure 1-3 As shown, it is worth noting that in order to fix the cable 5 while allowing the collar 1 to be quickly fixed to the outside of the insulator 4, the driving synchronization assembly 3 is provided, including a U-shaped movable rod 33 fixed to the outer arc wall of the clamping seat 2. The U-shaped movable rod 33 is movably inserted into the collar 1. The inner side wall of the U-shaped movable rod 33 is fixed to the inner wall of the collar 1 by an S-shaped spring piece 36. The U-shaped movable rod 33 is movably sleeved on the outside of two symmetrically arranged inverted L-shaped pressure rods 31. The bottom end of each inverted L-shaped pressure rod 31 is provided with a first inclined surface 32. The U-shaped movable rod 33 is provided with a sleeve groove 34 that cooperates with the inverted L-shaped pressure rod 31. The inner wall of the sleeve groove 34 is provided with a second inclined surface 35 that is parallel to the first inclined surface 32. The cross-sectional width of the sleeve groove 34 is equal to the cross-sectional width of the bottom end of the inverted L-shaped pressure rod 31.
[0027] Among them, after the inverted L-shaped pressing rod 31 is pulled out of the sleeve groove 34, the rebound force of its S-shaped spring piece 36 causes the second inclined surface 35 in the sleeve groove 34 to spring back to directly below the first inclined surface 32, so that it can be pressed again when the first inclined surface 32 moves down. Figure 1 and 2 The S-shaped spring 36 is in a stretched state, attached Figure 3 The S-shaped spring clip 36 is in a rebound state.
[0028] Further as Figure 1-3 As shown, it is worth noting that rubber pads are fixed to the inner arc walls of both clamping seats 2.
[0029] The rubber pad increases the friction during clamping, allowing it to be clamped to the outside of the insulator 4.
[0030] In summary: When using this high-altitude installation auxiliary positioning device for transmission line hardware, first place the cable 5 into the groove at the top of the insulator 4, and insert the guide rods 14 at the bottom of the two pressure blocks 13 into the guide holes 141 on the collar 1. Then, by rotating the hand-tightening bolt 15, the hand-tightening bolt 15 spirals into the screw hole 151 on the collar 1, so that the inverted V-shaped pressure grooves at the bottom of the two pressure blocks 13 can clamp the cable 5 in the V-shaped support groove 12, achieving positioning. At the same time, the bottom of the inverted L-shaped pressure rod 31... The first inclined surface 32 moves down to press against the second inclined surface 35 opened in the groove 34 on the upper sleeve of the U-shaped movable rod 33, causing the two U-shaped movable rods 33 to move towards each other, and making the two clamping seats 2 clamp and fix them on the outside of the insulator 4. This achieves the fixation of the cable 5 at the same time, and also allows the collar 1 to be linked and fixed on the outside of the insulator 4, which greatly improves the efficiency of high-altitude installation auxiliary positioning. In addition, the height of the two pressure blocks 13 can be adjusted according to the diameter of the installed cable 5, so as to meet the installation of cables 5 with different diameters.
