Description

An insulating hanger

technical field

The utility model belongs to the technical field of an insulating hanger used for live inspection and replacement of ±500kV and ±800kV tension single-chip insulators.

Background technique

In the operation of live replacement of tension-resistant single-piece insulators on high-voltage transmission lines, the connection method of insulating rope sleeves and insulating pulleys is currently used to transfer working tools and materials up and down through insulating ropes. In the process of transferring the fixture, due to the elasticity of the rope sleeve itself, the elastic elongation occurs when the force is applied to move the lifting point downward, and due to the increase in the voltage level, the weight of the operating tool increases sharply, and the operator lifts and installs the fixture. 1. The difficulty of the insulator increases, which increases the time spent on the whole work and reduces the work efficiency, which affects the reliability of power supply and the safety of work to a certain extent. If the insulating rope is too loosely wound on the insulator string, the lifting point will move down a greater distance, and the operator may lose balance during lifting with one hand due to the heavy weight of the tools and insulators in the process of taking a prone position and reaching out to grab the fixture or insulator , or even fall from a high altitude, resulting in insufficient clearance with the drainage wire combination, causing electric shock accidents.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems of the prior art, to provide a lifting point that can improve the lifting point, and without the use of a rope sleeve, the clamp and insulator can be lifted by the cooperation of the ground personnel, and the labor intensity and operation risk of the personnel on the tower can be reduced. insulated hangers.

The purpose of this utility model is achieved through the following technical solutions.

An insulating hanger, comprising a long horizontal insulating pull plate, symmetrically arranged in pairs and four insulating rods with aluminum alloy support frames at the bottom, which are installed on both sides of the insulating pull plate and The stopper and anti-drop insulating screws located outside the aluminum alloy support frame, the self-plugging insulating pulleys that are set on the insulating pull plate and located between the aluminum alloy support frames on both sides; The circular structure formed by the circular arc frame and the adjustable connecting screw on both sides.

In the utility model, an insulating rotating support head with a collar is installed on the upper end of the insulating rod, and the insulating rod is set on the insulating pull plate through the collar of the insulating rotating supporting head. The upper semi-arc plate of the aluminum alloy support frame is inserted or screwed onto the insulating rod through the sleeve section at the top.

After the utility model is assembled, it is hoisted to the operator as a whole, and the operator loosens the adjustable connecting screws of the four aluminum alloy support frames, and buckles the upper and lower halves of the circular arc frame on the left and right symmetrical sides of the tension-resistant double-string insulator. On the arc-shaped steel caps of the four tension insulators, tighten the adjustable connecting screw, and fix the utility model on the tension double-string insulator strings, and the hoisting position of the lifting equipment will be raised from the bottom of the original insulators to the height of the insulation hanger. on the tackle. During operation, the operator only needs to install the insulating hanger as described above, and put the hoisting rope of the lifting operation tool (fixture) on the pulley of the insulating hanger, and the ground personnel will pass the hoisting rope on the insulating hanger. The operating tool (fixture) is passed to the operator. Due to the improvement of the lifting position, the operator does not need to bend down to lift the operating tool (fixture) to the installation position like the traditional operation method, and only needs to direct the ground personnel to lift the operating tool. The appliance is raised to the required installation height and can be installed directly. The utility model is simple and light in structure and easy to install. When the utility model is used to replace the tension-resistant single-chip insulator, the operating tools (clamps) can be easily installed, reducing the labor intensity of operating personnel and reducing operating risks.

The utility model can be processed by using existing insulating pull plates and insulating rods, and the installation process is simple. It only needs to loosen the screws of the adjustable connecting screw rod, open the upper and lower halves of the support frames, fit them on the insulators, and tighten the screws.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, the insulating hanger includes a horizontal strip-shaped insulating pull plate 5, and four insulating rods 2 with aluminum alloy support brackets 1 at the bottom, which are arranged symmetrically in pairs and whose top ends are set on both sides of the insulating pull plate. The stopper and anti-drop insulating screws 4 on both sides of the insulating pull plate and outside the aluminum alloy support frame, the self-plugging insulating pulley 6 that is sleeved on the insulation pull plate and positioned between the aluminum alloy support frames on both sides; the aluminum alloy support frame 1 is a circular structure formed by connecting the upper and lower two halves of the circular arc frame and the adjustable connecting screw rod 7 on both sides. An insulating rotating support head 3 with a collar is installed on the upper end of the insulating rod 2, and the insulating rod is set on the insulating pull plate 5 through the collar of the insulating rotating supporting head. The upper semi-arc plate of the aluminum alloy support frame 1 is inserted or screwed onto the insulating rod 2 through the sleeve section at the top. The parts of the insulating hanger are mostly made of epoxy resin material, which is light in weight and high in strength, and will not increase the extra burden on the operators.

The utility model is used in the lifting and installation work of the tension-resistant single-chip insulator operating tool (clamp) for live replacement in the transmission network, as shown in Figure 1, Figure 2, and Figure 3. The operation steps are as follows:

1) The operator lifts the insulating hanger and stands it on the tension-resistant double-string insulator string 10, loosens the adjustable connecting screw 7, clamps the upper and lower halves of the aluminum alloy support frame 1 on the steel cap of the insulator, and tightens the screws;

2) The operator puts the lifting rope 9 on the pulley 8 of the self-plugging insulating tackle 6;

3) The ground personnel pull the sling to lift the entire operating tool (fixture).
