Description

Special operating lever and operation method for quick installation of ground wire

technical field

The invention relates to a special operating rod for quick installation of ground wires and an operating method.

Background technique

The special operating rod for quickly installing the grounding wire is a special tool for installing and wiring the power transmission line when the power is cut off. In the case of power outage operation and maintenance of 220kV and above voltage transmission lines, it is necessary to install grounding wires on the three-phase conductors at both ends of the work area to ensure the personal safety of operators. Under the current conditions, operators use the throwing method to install the grounding wire. Due to the influence of the tower type, wire position and climate (especially in windy weather), the installation of the grounding wire is time-consuming and laborious, which is not conducive to the personal safety of the operators and affects the power outage operation. Bad results for efficiency.

Contents of the invention

Aiming at the deficiencies in the prior art, the present invention discloses a special operating lever and operation method for quick installation of ground wires. time, reduce the operation risk, and improve the efficiency of power outage operation.

The present invention is achieved by the following technical means:

Quickly install the special operating lever for the ground wire, including the opening and closing clips connected to the round pipe through the clip shaft, the opening and closing clips are fixedly connected with the slotted ground wire clip clips, and the bottom of the round pipe is equipped with a rotary connector, and the rotary connector is connected to the hollow wire tube Connection, the hollow wire tube is fixedly connected with the inner insulating tube; the hollow wire tube is covered with matching nuts, and the nuts are fixedly connected with the outer insulating tube. Sliding wheels are installed on the opening and closing clips.

The rotary connector can also be replaced by a processed bearing sleeve structure.

Positioning pins are also arranged on the clip of the grooved ground wire clamp.

The inner insulating tube and the outer insulating tube are respectively wrapped with rubber insulating handles.

The operation method for quickly installing the special operating lever for the ground wire is characterized in that it includes the following steps:

(1) Place the grounding wire clamp to be installed in the grooved grounding wire clamp clip, and the positioning pin will play a fixed role;

(2) Hold the outer insulating tube with one hand, and the inner insulating tube with the other hand, and turn the inner insulating tube clockwise to drive the round tube and the opening and closing clips to move in the direction of the hand. Due to the action of the sliding wheel, the contraction The bracket supports the opening and closing clip so that it is stressed toward the inner corner, so that the front end of the grounding wire clamp is opened to wrap the wire.

The advantages and beneficial effects of the present invention are as follows: the present invention adopts the principle of lever machinery, which is labor-saving in operation, convenient in application, shortens the time for installing grounding wires, simplifies the procedure of high-altitude operations, reduces the time for high-altitude operations, and thus reduces the number of workers. Reduce operational risks and labor intensity, while improving the efficiency of power outage operations. The invention is easy to carry, easy to operate, labor-saving and low in cost, and is easy to popularize and use in the field of power transmission production.

Detailed ways

Example 1:

As shown in Figure 1, a special operating lever for quick installation of ground wires includes opening and closing clip 1 connected to round pipe 7 through clip shaft 3, opening and closing clip 1 is welded and fixed with slot-type ground wire clamp clip 2, and round pipe 7 The lower part is equipped with a rotary connector 8, the rotary connector 8 is connected with the hollow wire tube 9, and the hollow wire tube 9 is fixedly connected with the top of the inner insulating tube 11; the hollow wire tube 9 is also covered with a wire mother 10, and the wire mother 10 is insulated from the outside The top of the pipe 12 is fixedly connected, the bottom end of the shrink bracket 5 is fixedly welded with the screw nut 10, and the top is equipped with a sliding wheel 6 which pushes against the opening and closing clips 1 on the left and right sides respectively. Positioning pins 4 are also housed on the grooved ground wire clamp clip 2 . The inner insulating tube 11 and the outer insulating tube 12 are wrapped with rubber insulating handles 13 respectively.

Production process: The opening and closing clips are made of 20mm wide and 4mm thick steel plates, and the slotted grounding wire clips are welded with the opening and closing clips. . The hollow wire tube of the retractable bracket and the screw nut can be rotated so that the opening and closing clips can move 35-40mm. The inner insulating tube is an insulating tube with a diameter of 20mm and a length of 2800mm. The outer insulating tube is an insulating tube with a diameter of 30mm and a length of 2500mm.

Operation method:

(1) Place the grounding wire clamp to be installed in the grooved grounding wire clamp clip 2, and the positioning pin 4 will play a fixed role;

(2) Hold the outer insulating tube 12 with one hand, hold the rubber insulating handle 13 on the inner insulating tube with the other hand, turn the inner insulating tube 11 clockwise, and drive the round tube 7 together with the opening and closing clip 1 to hold direction movement, due to the effect of sliding wheel 6, the retractable bracket 5 supports the opening and closing clip 1 and makes it stressed to the inner corner, so that the front end of the ground wire clamp is open and wraps up the wire.
