Description

Technical Field

[0001] The present invention relates to the technical field of electric line fixing, in particular to a wire clamp hanging plate for a high-voltage transmission line and an installation method thereof. Background Art

[0002] High-voltage transmission line clamps are devices used to secure and suspend cables or conductors in high-voltage transmission lines. These clamps are typically used in conjunction with wire clamps to ensure that cables or conductors are securely mounted on the transmission line's supporting structure, such as a tower or pole. The design and manufacture of these clamps must meet the specific requirements of high-voltage power transmission to ensure safe, reliable, and efficient operation of the power system.

[0003] Chinese patent publication number CN217824167U discloses a high-strength, wear-resistant power bracket. The bracket includes a support assembly that provides a connection and support for the bracket's original hollow portion. This significantly improves the bracket's deformation resistance, structural reliability, and service life, particularly for larger brackets. Furthermore, a wear-resistant liner is installed in the suspension groove, replacing the frictional contact between the connecting hardware and the U-shaped plate connection body with frictional contact between the wear-resistant liner and the connecting hardware. This significantly improves the bracket's wear resistance and ensures reliable connection between the hardware.

[0004] When the power hanging plate of the above patent reduces friction through the wear-resistant plate, although the wear-resistant plate wraps the friction-affected position, the friction force will be transferred to the surface of the wear-resistant plate, and the friction force will cause damage to the wear-resistant plate. The wear-resistant plate needs to be replaced frequently, which affects the service life of the wire clamp hanging plate. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In order to solve the problem that when existing power hanging plates use wear-resistant plates to reduce friction, although the wear-resistant plates wrap the friction-affected parts, the friction force will be transferred to the surface of the wear-resistant plates, causing damage to the wear-resistant plates. Friction will cause damage to the wear-resistant plates, requiring frequent replacement of the wear-resistant plates, and affecting the service life of the wire clamp hanging plates, this embodiment provides the following technical solutions:

[0034] A wire clamp hanging plate for high-voltage transmission lines includes a hanging plate bracket 1, an upper connecting rod 2 is horizontally arranged at the upper end of the hanging plate bracket 1, and a lower connecting rod 3 is horizontally arranged at the lower end of the hanging plate bracket 1. The upper connecting rod 2 is used to connect with the connecting hardware on the upper side, and the lower connecting rod 3 is used to connect with the connecting hardware on the lower side. The upper connecting rod 2 and the lower connecting rod 3 are vertically arranged. Figure 1 、 Figure 2 And Figure 3 As shown in the figure, the lower connecting rod 3 and the outside of the upper connecting rod 2 are provided with a second connecting frame 5, one side of the second connecting frame 5 is provided with a first connecting frame 4, and the second connecting frame 5 and the first connecting frame 4 are welded and fixed with the hanging plate support 1. The inside of the lower connecting rod 3 and the upper connecting rod 2 is provided with a rotatable rotating handle 6, one end of the rotating handle 6 towards the first connecting frame 4 is provided with a first threaded wall 8, the inside of the first connecting frame 4 is provided with a second threaded wall 18 which is threadedly matched with the first threaded wall 8. The rotating handle 6 moves towards the first connecting frame 4 and penetrates the fitting. After penetration, the fitting is fixed by thread cooperation. Thus, it is supported and connected by the hanging plate support 1, and the inside of the second threaded wall 18 is threadedly matched with the outside of the first threaded wall 8.

[0035] In this embodiment, one end of the first connecting frame 4 and the second connecting frame 5 towards the middle position of the hanging plate support 1 is provided with a second annular track 22, and the second annular track 22 is recessed in the inside of the hanging plate support 1, as shown in Figure 4 And Figure 5 As shown in the figure, both sides of the inside of the second annular track 22 are provided with a connecting ring 9, and the connecting ring 9 is welded and fixed with the hanging plate support 1. One side of the outside of the two connecting rings 9 is slidingly provided with an anti-skid piece 10. After the rotating handle 6 is rotated and penetrates the fitting, the internally fixed fitting will be blocked by the anti-skid piece 10 to protect the hanging plate support 1. After friction, the friction force will drive the anti-skid piece 10 to rotate in the inside of the second annular track 22. The friction force is directly offset by sliding rotation, avoiding damage to the anti-skid piece 10 and the hanging plate support 1 caused by friction;

[0036] In this embodiment, the inside of the anti-skid piece 10 is provided with a first annular track 21 towards the middle position of the hanging plate support 1, and the outside of the first annular track 21 is provided with a rubber pad 11 made of rubber material. The rubber pad 11 replaces the contact between the anti-skid piece 10 and the fitting penetrated by the rotating handle 6. The fitting can stably drive the rubber pad 11 and the anti-skid piece 10 to rotate after rotation by the rubber material;

[0037] In this embodiment, as shown in Figure 4 , Figure 6 And Figure 7 As shown in the figure, one side of the outside of the anti-skid piece 10 is provided with an extension piece 15 for transmission, and the inside of the extension piece 15 is provided with an adjusting block 16, and the outside of the adjusting block 16 is threadedly matched with the inside of the rubber pad 11. The rotation of the adjusting block 16 in combination with the limitation of the first annular track 21 can drive the rubber pad 11 to adjust the horizontal position. The fine adjustment of the position of the rubber pad 11 can make the rubber pad 11 closely contact with the connected fitting, so that the fitting can stably drive the anti-skid piece 10 to rotate when rotating;

[0038] In this embodiment, a fixed frame 12 connected to the card slot is provided on one side of the outer portion of the extension piece 15, and a gasket 13 resting on the surface of the hardware is provided on one side of the outer portion of the fixed frame 12. The gasket 13 is rotatably connected to the fixed frame 12 via a damping shaft 14. Figure 4 and Figure 5 As shown, the rotation connection of the damping shaft 14 allows the gasket 13 to rest on the surface of the hardware. When the hardware rotates, it can directly drive the anti-slip sheet 10 to rotate through the transmission of the gasket 13 and the fixed frame 12, and the friction is directly offset by the rotation.

[0039] In this embodiment, a support block 20 is provided at the lower end between the two connecting rings 9, and the support block 20 is welded and fixed to the anti-slip sheet 10. Figure 5 and Figure 6 As shown, springs 19 are provided between the two sides of the support block 20 and the connecting ring 9. The rotation of the anti-slip sheet 10 will squeeze the spring 19, and the resilience of the spring 19 will actively drive the fixed hardware to reset.

[0040] In this embodiment, if Figure 2 and Figure 3 As shown, recessed transverse sliding rails 7 are provided at the upper and lower ends of the interior of the lower connecting rod 3, and sliding blocks 17 are slidably provided at the upper ends of the outside of the two transverse sliding rails 7, and the sliding blocks 17 are welded and fixed to the hanging plate bracket 1. The sliding blocks 17 are embedded in the transverse sliding rails 7 and the lower connecting rod 3 and the internal rotating handle 6 are continuously suspended and fixed to prevent the rotating handle 6, the lower connecting rod 3 and the first connecting frame 4 for connection from being separated from the outside of the hanging plate bracket 1. The rotating handle 6, the lower connecting rod 3 and the first connecting frame 4 are an integrated structure with the hanging plate bracket 1, which facilitates the rotation and fixation of the rotating handle 6 and improves the installation and disassembly efficiency of the hardware.

[0041] The installation method of the wire clamp hanging plate for high-voltage transmission lines includes the following steps:

[0042] Step 1: When installing and connecting the hardware at the position of the upper connecting rod 2, the penetration position of the hardware is placed at the upper end of the interior of the hanging plate bracket 1, and the penetration position overlaps with the center position of the upper connecting rod 2. Slide the upper connecting rod 2 horizontally, and slide the upper connecting rod 2 horizontally so that the upper connecting rod 2 passes through the hardware and fits the first connecting frame 4;

[0043] Step 2: Turn the rotating handle 6. The rotation of the rotating handle 6 can rotate the first threaded wall 8 that is in contact with the first connecting frame 4. The rotation of the first threaded wall 8 and the second threaded wall 18 inside the first connecting frame 4 generate relative motion.

[0044] Step 3: After the rotation of the rotating handle 6 is restricted by the sliding block 17 on the transverse sliding rail 7, the upper connecting rod 2 is embedded in the first connecting frame 4;

[0045] Step 4: Rotate the adjustment block 16. After the adjustment block 16 rotates and is restricted by the first annular track 21, the rubber pad 11 can move toward the outer wall of the hardware. After fine-tuning the rubber pad 11, the rubber pad 11 is closely attached to the hardware.

[0046] Step 5: When installing and connecting the hardware at the position of the lower connecting rod 3, the penetration position of the hardware is placed at the lower end of the interior of the hanging plate bracket 1, and the penetration position overlaps with the center position of the circle of the lower connecting rod 3. Slide the lower connecting rod 3 horizontally and repeat steps 2 to 4;

[0047] Step 6: The rotation and shaking of the hardware will directly drive the anti-skid sheet 10 to rotate in the second annular track 22. After being restricted by the connecting ring 9, the anti-skid sheet 10 can rotate along the second annular track 22, and the rotation directly offsets the damage caused by friction.
