Description

Technical Field

[0001] The invention belongs to the technical field of power wire support, and in particular relates to a connection structure between a clamp for supporting a power wire and an insulator. Background Art

[0002] Power wires are an important medium for electric energy transmission. They are widely used in various fields and provide indispensable power support for modern society. Power wires refer to wires used to transmit electric energy, usually composed of conductors, insulation layers and protective layers. Their specific categories are: bare wires: wires without insulation layers, mainly made of metals such as copper and aluminum, used for power transmission and communication lines; insulated wires: wires with insulation layers, the conductors can be copper, aluminum or steel, etc., and the insulation layers are made of materials such as plastic and rubber. They are widely used in household circuits, industrial equipment and building facilities. Electromagnetic wires: insulated wires that generate magnetic fields or induce currents in magnetic fields when energized, mainly used in coils of equipment such as motors and transformers; power wires are composed of the following parts: core wire: the core part of the power wire, usually made of highly conductive materials such as copper or aluminum; insulating sheath: the insulating layer wrapped around the outside of the core wire to prevent current leakage and short circuit, usually made of insulating materials such as plastic and rubber; protective sheath: the protective layer located outside the insulating layer, used to protect the wires from damage from the external environment, such as wear and corrosion.

[0003] The support of power lines is a vital part of the power system. It ensures that the lines can transmit electric energy stably and safely. In the power line support system, the selection of supporting components and connectors is equally important. These components and connectors should be products that meet national standards and undergo strict inspection and testing to ensure their quality and safety. Common supporting components include cable racks, bridges, crossarms, etc. They are used to fix and support wires to prevent them from sagging or swinging. Connectors are used to connect supporting components to wires or poles to form a stable support system.

[0004] The connection structure between the power wire support clamp and the insulator is a key part in the power system. It ensures that the wire can be stably mounted on the support structure and effectively connected to the insulator, thereby ensuring the safety and reliability of power transmission. The connection structure between the power wire support clamp and the insulator is mainly composed of a clamp, an insulator and a connector. The clamp is used to clamp the power wire, the insulator plays the role of electrical isolation and mechanical support, and the connector is responsible for firmly connecting the clamp and the insulator together. The connection structure between the power wire support clamp and the insulator plays a vital role in the power system. Through reasonable design and selection, the stable transmission and electrical safety of the power wire can be ensured.

[0005] Usually, power lines are installed in various forms above or below ground from power plants to users. Among the above-ground installation methods, utility poles are mainly used. By installing utility poles at certain intervals to support the power lines, it can be ensured that the power lines can be firmly installed and maintain their stability. However, in the prior art, clamps and insulators are usually connected by bolts, which are cumbersome to disassemble. It is inconvenient for workers to disassemble the clamps and insulators, thereby reducing the work efficiency of workers in maintaining the power lines.

[0006] The connection structure between the power line support clamp and the insulator of the present invention is equipped with a second cotter pin of the elastic hook rod, so that the connection and separation work between the clamp and the insulator can be carried out safely and quickly, thereby improving the efficiency and stability of the power line maintenance work;

[0007] The clamp and the insulator can be simply and stably connected, and they can be easily separated. Compared with the bolt installation method, it is convenient for workers to disassemble the clamp and the insulator, thereby improving the work efficiency of workers in power line maintenance work. Summary of the invention

[0008] The object of the present invention is to provide a connection structure between a clamp for supporting a power line and an insulator, which can quickly and stably complete the connection or separation work between the clamp and the insulator, thereby improving the work efficiency of the staff in the maintenance work of the power line.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] A connection structure between a clamp for supporting a power line and an insulator comprises a support rod, a power line, an insulator and a clamp, wherein the clamp is provided with a wedge-shaped body which gradually narrows at the front and a shell formed inside, a pair of slidable jaws are provided inside the shell, an arm body for connecting with the insulator is provided at the rear of the shell, an auxiliary arm is provided at the rear end of the arm body, a first cotter pin is provided at the front end of the insulator, a bayonet pin is inserted at the front end of the first cotter pin, a second through hole, a third through hole and a first through hole are respectively provided on the arm body, the auxiliary arm and the insulator, a second cotter pin is connected through the second through hole, the third through hole and the first through hole, an elastic hook rod is connected to the second cotter pin, a groove is provided on the second cotter pin, and a socket is provided at the bottom of the second cotter pin.

[0011] Preferably, both ends of the elastic hook rod protrude from the second cotter pin to form a spiral spring structure.

[0012] Preferably, the elastic hook rod is inserted into the interior of the insertion hole formed at the bottom of the second cotter pin by means of a chimerical manner.

[0013] Preferably, the bottom of the first cotter pin is located inside the protection box.

[0014] Preferably, the grooves are located on both sides of the second cotter pin.

[0015] By setting the above technical solution, when connecting the clamp and the insulator, as shown in the figure, the front end of the insulator is inserted between the arm body and the auxiliary arm of the clamp, so that the second through hole and the third through hole on the arm body and the auxiliary arm are aligned with the first through hole of the insulator, and then the second cotter pin equipped with the elastic hook rod is pushed into the second through hole, the third through hole and the first through hole;

[0016] When the two ends of the elastic hook rod protruding from the second cotter pin pass through the second through hole, the third through hole and the first through hole, the two ends will bend upward elastically, so that the distance between the two ends is reduced, and the two ends can pass through the second through hole, the third through hole and the first through hole smoothly;

[0017] After the elastic hook rod passes through the second through hole, the third through hole and the first through hole, the bent ends thereof will elastically recover and unfold again to return to their original state;

[0018] After the elastic hook rod is restored to its original state, as shown in the figure, since the length of the elastic hook rod is greater than the diameter of the second through hole, the elastic hook rod will be stuck on the arm body of the clamp, thereby ensuring that the second cotter pin will not be disengaged from its original position without human intervention;

[0019] In order to separate the clamp and the insulator, it is necessary to pull out the second cotter pin inserted into the second through hole, the third through hole and the first through hole. At this time, the operator grabs the second cotter pin and pulls it outward to make the elastic hook rod bend elastically, and the second cotter pin can be pulled out through the second through hole, the third through hole and the first through hole.

[0020] Through the above operation, the clamp and the insulator can be simply and stably connected, and they can be easily separated. Compared with the bolt installation method, it is convenient for the staff to disassemble the clamp and the insulator, thereby improving the work efficiency of the staff in the maintenance of power lines.

[0021] The fixing structure of the elastic hook rod is that when the elastic hook rod is inserted into the insertion hole of the second cotter pin, the bottom of the second cotter pin is knocked with a tool to deform the protrusion inside the insertion hole, so that the elastic hook rod can be tightly pressed into and fixed inside the insertion hole.

[0022] The fixing structure of the elastic hook rod utilizes the characteristics of the second cotter pin made of metal material. Compared with the method of fixing the elastic hook rod to the second cotter pin using adhesive or the like, the working speed is faster and the fixing state is more stable.

[0023] The connection structure between the clamp and the insulator for supporting the power wire can be applied not only to the clamp and the insulator, but also to all components with a detachable connection structure for supporting the power wire;

[0024] In summary, the connection structure between the power line support clamp and the insulator of the present invention, by being equipped with a second cotter pin of the elastic hook rod, enables the connection and separation of the clamp and the insulator to be carried out safely and quickly, thereby improving the efficiency and stability of the power line maintenance work.

[0025] Preferably, a protective mechanism is connected to the bottom of the arm body to protect the bottom positions of the first cotter pin and the second cotter pin to prevent their bottoms from being damaged by corrosion. The protective mechanism includes a protective box, an outer wall of the protective box is connected to a connecting rope, and an end of the connecting rope away from the protective box is connected to a sliding plug plate.

[0026] Preferably, a sliding slot is provided on the protection box.

[0027] Preferably, the sliding plug plate is slidably connected to the protection box through a sliding slot.

[0028] Preferably, the length of the elastic hook rod is greater than the length of the second through hole.

[0029] Preferably, the second cotter pin is slidably arranged with the second through hole, the third through hole and the first through hole respectively.

[0030] By setting the above technical solution, according to the effect that the bottoms of the first cotter pin and the second cotter pin are located inside the protection box, the bottoms of the first cotter pin and the second cotter pin can be protected to prevent them from being corroded by the outside air, thereby improving the use and removal effect of the first cotter pin and the second cotter pin;

[0031] It should be noted that: according to the function of the connecting rope, the sliding plug board can be stably located on one side of the protection box, which is convenient for the staff to plug and use the sliding plug board.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The connection structure between the power line support clamp and the insulator of the present invention is equipped with a second cotter pin of the elastic hook rod, so that the connection and separation work between the clamp and the insulator can be carried out safely and quickly, thereby improving the efficiency and stability of the power line maintenance work;

[0034] The clamp and the insulator can be simply and stably connected, and they can be easily separated. Compared with the bolt installation method, it is convenient for workers to disassemble the clamp and the insulator, thereby improving the work efficiency of workers in power line maintenance work.

[0035] Through the function of the protection mechanism, the bottoms of the first cotter pin and the second cotter pin are located inside the protection box, so that the bottoms of the first cotter pin and the second cotter pin can be protected to prevent them from being corroded by the outside air, thereby improving the use and removal effect of the first cotter pin and the second cotter pin;

[0048] The present invention further specifically describes that the two ends of the elastic hook rod 22 protrude from the second cotter pin 20 and form a spiral spring structure, the length of the elastic hook rod 22 is greater than the length of the second through hole 10a, and the elastic hook rod 22 is inserted into the inside of the insertion hole 20b formed at the bottom of the second cotter pin 20 by a chimeric manner, the bottom of the first cotter pin 12 is located inside the protection box 3, the second cotter pin 20 is respectively slidably arranged with the second through hole 10a, the third through hole 10b and the first through hole 8a, and the groove 20a is located on both sides of the second cotter pin 20;

[0049] As can be seen from the above, when connecting the clamp 10 and the insulator 8, Figure 4 As shown, the front end of the insulator 8 is inserted between the arm body 103 and the auxiliary arm 104 of the clamp 10, so that the second through hole 10a and the third through hole 10b on the arm body 103 and the auxiliary arm 104 are aligned with the first through hole 8a of the insulator 8, and then the second cotter pin 20 equipped with the elastic hook rod 22 is pushed into the second through hole 10a, the third through hole 10b and the first through hole 8a;

[0050] When the two ends of the elastic hook rod 22 protruding from the second cotter pin 20 pass through the second through hole 10a, the third through hole 10b and the first through hole 8a, they will bend upward elastically, so that the distance between the two ends is reduced, and the elastic hook rod 22 can pass through the second through hole 10a, the third through hole 10b and the first through hole 8a smoothly;

[0056] The fixing structure of the elastic hook rod 22 utilizes the characteristics of the second cotter pin 20 made of metal material. Compared with the method of fixing the elastic hook rod 22 to the second cotter pin 20 using adhesive or the like, the working speed is faster and the fixing state is more stable.

[0057] The connection structure between the power wire supporting clamp 10 and the insulator 8 can be applied not only to the above-mentioned clamp 10 and the insulator 8, but also to all components for supporting power wires with a detachable connection structure;

[0058] In summary, the connection structure between the power line supporting clamp 10 and the insulator 8 of the present invention, by being equipped with a second cotter pin 20 of an elastic hook rod 22, enables the connection and separation of the clamp 10 and the insulator 8 to be carried out safely and quickly, thereby improving the efficiency and stability of the power line maintenance work.
