Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a quick-release power line crossarm. Background Technology

[0002] A power line crossarm is an angle iron fixed horizontally at the top of a utility pole, fitted with porcelain insulators, used to support overhead power lines. It is an important component of the pole tower, its main function being to install insulators and fittings to support conductors and lightning protection wires, ensuring they maintain the prescribed safe distance.

[0003] Existing power line crossarms are fixed to utility poles using clamps and nuts during installation. The nuts are located inside the triangular bracket, which has limited space and is inconvenient to operate. In addition, multiple sets of nuts are used to lock the crossarm in place to prevent loosening. This requires removing nuts frequently, making it difficult to quickly disassemble the power line crossarm. To solve the above problems, this application proposes a quick-disassembly and assembly power line crossarm. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a quick-disassembly and assembly power line crossarm. The fixing screw on the fixed clamp is rotatably connected to the rotating clamp through a rotating connecting seat. The locking connecting ear at the end of the rotating clamp is locked by a fixing bolt. After the fixing bolt is removed, the two sets of rotating clamps can be unfolded outward, and the second splicing ring can be pushed up. The splicing groove and splicing socket can be separated, and the insulation ring can be disassembled. This enables the quick disassembly of the power line crossarm, thereby solving the problems mentioned in the background art.

[0006] (II) Technical Solution

A fixing hole is opened in the middle of the side wall of the triangular bracket. The fixing holes are symmetrically arranged, and a fixing clamp is movably installed in the cavity of the fixing hole. The fixing clamp has a U-shaped structure.

[0008] The fixing clamp consists of a fixing screw and a rotating clamp;

The mounting holes 2 are symmetrically opened at both ends of the triangular bracket 1, and the bottom of the insulating terminals 3 is fixed to the triangular bracket 1 by inserting and fixing bolts into the mounting holes 2. A fixing hole 6 is opened in the middle of the side wall of the triangular bracket 1. The fixing holes 6 are symmetrically arranged, and a fixing clamp 7 is movably installed in the cavity of the fixing hole 6. The fixing clamp 7 has a U-shaped structure.

[0028] The fixing clamp 7 consists of a fixing screw 8 and a rotating clamp 9;

[0029] The fixing screw 8 is inserted into the fixing hole 6. The fixing screw 8 and the rotating hoop 9 are rotatably connected by the rotating connecting seat 11. The two ends of the rotating hoop 9 that are close to each other are welded with locking connecting ears 10. The two sets of locking connecting ears 10 are connected by fixing bolts.

[0030] It should be noted that the bottom of the insulating terminal 3 is fixed to both ends of the triangular bracket 1 by inserting the fixing bolt into the mounting hole 2. When the triangular bracket 1 is hoisted to the top of the utility pole, the arc-shaped positioning seat 4 on the side wall of the triangular bracket 1 abuts against the surface of the utility pole. The triangular bracket 1 can be positioned by the arc-shaped positioning seat 4. The two ends of the fixing clamp 7 are inserted into the fixing hole 6 by fixing screw 8 and fixed by the fixing screw 8 with nuts. The triangular bracket 1 can be quickly installed on the utility pole by fixing clamp 7. The fixing screw 8 on the fixing clamp 7 is rotatably connected to the rotating clamp 9 by rotating connecting seat 11. The locking connecting ear 10 at the end of the rotating clamp 9 is locked by fixing bolt. After the fixing bolt is removed, the two sets of rotating clamps 9 can be unfolded outward, the second splicing ring 13 can be pushed up, the splicing groove 16 and the splicing socket 17 can be separated, and the insulating ring 5 can be disassembled, thereby realizing the quick disassembly of the crossarm of the power line.

The first splicing ring 12 is inserted into the fixing groove 14 through the fixing rod 15.

[0034] It should be noted that the fixing clamp 7 is clamped on the surface of the insulating ring 5. The insulating ring 5 can increase the friction and improve the stability of the installation of the tripod 1. It also serves as insulation to prevent current from being transmitted to the utility pole through the tripod 1 when the insulating terminal 3 is damaged, thus improving safety during use.

The first splicing ring 12 is inserted into the fixing rod 15 through the fixing groove 14 and fixed to the arc-shaped positioning seat 4. The fixing clamp 7 is... When fixing the triangular bracket 1, the fixing clamp 7 is clamped on the surface of the insulating ring 5. The insulating ring 5 increases the friction and improves the stability of the installation of the triangular bracket 1. It also serves as insulation to prevent current from being transmitted to the utility pole through the triangular bracket 1 when the insulating terminal 3 is damaged, thus improving safety during use. The fixing screw 8 on the fixing clamp 7 is rotatably connected to the rotating clamp 9 through the rotating connecting seat 11.
