Problems solved by technology

However, when taking the pulley, it is easy to cause the pulley to fall off, which will cause damage to the ground personnel.
The whole installation process consumes a lot of physical strength of the construction workers, and it is easy to sprain and squeeze the workers, which will affect the construction progress
[0003] At the same time, with the continuous increase of the transmission voltage of the power transmission system, higher requirements are placed on the bearing capacity of the suspension clamp. The traditional wires are fixed by binding for wires or optical cables, whether aluminum wire or self-adhesive tape is used. , after long-term aging and oxidation in the open air, it is easy to cause the wire or optical cable to fall off, and the discharge trip is not conducive to improving the reliability of the transmission line

Embodiment 1

[0021] The main structure of this embodiment, such as figure 1 As shown, a suspension clamp includes a hoop 1, an aluminum splint 3, a U-shaped hanging ring 5, a first hanging ring 6, an insulating clamp 7, an outer twisted wire 8, an inner twisted wire 9, and the inner twisted wire 9 Wrapping the wire 4, the insulating clamp 7 is fixed at the center of the inner twisted wire 9, and the outer twisted wire 8 is wound around the outer surface of the insulating fixture 7 with the central position of the insulating clamp 7 as a symmetrical axis. The aluminum splint 3 It is fixed at the center position outside the outer twisted wire 8, and the first hanging ring 6 at one end of the aluminum splint 3 is connected to the U-shaped hanging ring 5, and the U-shaped hanging ring 5 is connected to the hoop 1 through a nut, and the hoop 1 passes through The closed pin is fixed on the fastening fixture 2, and the present invention realizes the connection between the transmission medium wire...

Embodiment 2

[0023] In this embodiment, on the basis of Example 1, the insulating clamp 7 is further limited to be a rubber clamp. There are many options for the insulating clamp, and the rubber clamp is preferred here. The rubber clamp is composed of high-quality rubber and a central reinforcement, and has anti-ozone , chemical resistance, weather aging resistance, high and low temperature performance, small compression deformation, can effectively prevent the aging and oxidation of transmission media such as wires or optical cables, and at the same time reduce the friction between the aluminum splint and the transmission medium, reducing the friction Damage to the cable conductors. Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Embodiment 3

[0025] This embodiment further defines the first hanging ring 6 as a right-angle hanging ring on the basis of the above-mentioned embodiment. There are various structures of the first hanging ring. The connection of the ring 5 improves the bearing capacity of the suspension clamp; the center position of the inner twisted wire 9 coincides with the center position of the insulating clamp 7, and the positional relationship between the inner twisted wire and the insulating clamp 7 is further preferably restricted here, so as to The central position of the inner twisted wire 9 wound on the wire is a symmetrical point, and the insulating clamp is inlaid outside the inner twisted wire in two halves, the upper and lower halves, and fixed with a fixing device such as a thin adhesive tape, which enhances the protection of the wire and improves the safety of the wire. The ability to resist external influences; the gap between the outer twisted wires 8 is even, and there is no intersection...

Abstract

The invention discloses a suspension clamp which comprises a hoop, an aluminum clamp plate, a U-type hanging ring, a first hanging ring, an insulation clamp, outer twisted wires and inner twisted wires. The inner twisted wires are wrapped with wires. The insulation clamp is fixed to the center of the inner twisted wires. The outer twisted wires are wound around the outer surface of the insulation clamp with the center of the insulation clamp serving as a symmetry axis. The aluminum clamp plate is fixed to the center of the outer side of the outer twisted wires. The first hanging ring of one end of the aluminum clamp plate is connected with the U-type hanging ring. The U-type hanging ring is connected with the hoop through a nut. The hoop is fixed to a fastening clamp through a closed pin. Due to the arrangement of the insulation clamp, the aluminum clamp board, the outer twisted wires and the inner twisted wires, the service life of the wires and the suspension clamp which are fixed in a severe environment is prolonged, the wires are effectively prevented from falling down, the aging-resistant performance and the oxidizing-resistant performance of the wires are improved, and the suspension clamp is simple in structure, easy to operate and install and capable of effectively relieving the labor intensity of workers in the installation process.

Description

technical field [0001] The invention relates to the technical field of electric fittings, in particular to a suspension clamp for transmission lines. Background technique [0002] Suspension wire clips are often produced by aluminum alloy material casting process. The structure is anti-halo type bag type. inside the trunking. Suspension clamps are commonly used standard fittings on 35KV transmission lines, and they are used together with insulators to support the lines. When erecting high-voltage lines, if conventional suspension clamps are used, the wires must be erected with the help of pulleys, and then the very heavy wires must be supported by the arms of the construction workers, and the wires must be put into the wire clamps. But it is easy to cause the pulley to come off when taking the pulley, thereby causing the damage of the personnel on the ground. The whole installation process consumes a lot of physical strength of the construction workers, and it is easy to ...
