Insert the advance and retreat scales into the insulator operating rod, and the rotating operating rod drives the gear on the rotating shaft to rotate, and the rotation of the gears engages Advance and retreat the ruler, make the advance and retreat ruler move horizontally, so that the clamp handles can be closed or separated, and the insulator can be replaced or repaired when the insulator is charged. The advantage of the utility model is: by using the insulator pin remover of the utility model, Guaranteed to replace and repair insulators with problems in a timely manner under live conditions, flexible operation, fast and convenient use, thus effectively avoiding the situation that insulators cannot be replaced due to problems.

Description

New type insulator pin remover

Technical field:

The invention belongs to a special tool for maintenance of electrical equipment of transmission lines in the power supply industry, and in particular relates to a special canceler for bowl heads in live replacement linear insulator strings of 110KV-220KV transmission lines.

Background technique:

At present, with the development of the electric power industry, the number of transmission lines continues to increase, and the daily maintenance of transmission lines has become more and more arduous. Because the line fittings are constantly improving. For example: the 220KV Fuying 2759 line under the jurisdiction of our work area, due to the use of a new connection method, the opening of the bowl head faces the tower, and the opening of the bowl head follows the direction of the line during normal connection, but the opening of the bowl head faces the tower in the new connection method. Live maintenance, live replacement of insulators and other operations bring a lot of trouble. Operators cannot perform live operations to replace insulator strings. This is because the original insulator pin remover cannot be used. The safety risk also increases, and the labor intensity of the equipotential operators also increases. If the power outage is carried out, it will cause losses to the enterprise due to production stoppage.

Invention content:

In order to adapt to the maintenance of insulators under the new line fittings (bowl heads), the utility model discloses a novel insulator pin remover. It can make straight insulator strings of any transmission line. When the opening of the bowl faces the pole tower, the maintenance workers can use the new insulator remover of this project on the live line to ensure timely replacement and maintenance of problematic insulators under live conditions. Thereby effectively avoiding the situation that the insulator cannot be replaced due to a problem, resulting in a power outage of the line. At the same time, it also reduces the labor intensity of operators, reduces safety risks, eliminates hidden dangers of line safety and improves work efficiency.

The utility model is achieved through the following technical solutions:

A new type of insulator pin remover, which welds two fixing clips on the pliers handle of the existing insulator pin remover, inserts the transmission shaft into the fixing clips and fixes them, and fixes one end of the advancing and retreating rulers with fixing pins, and the middle is from the The transmission shaft is fixed by passing through it, and the top end is fixed with the fixed pin of the other pincer handle of the pin remover. Insert the advance and retreat scales into the insulator operating rod, and the rotating operating rod drives the gear on the rotating shaft to rotate, and the rotation of the gears engages Advance and retract the ruler, make the advance and retreat ruler move horizontally, so that the clamp handles are closed or separated, and the insulator is replaced or repaired under live conditions.

The scale is engraved on the described advancing and retreating ruler.

One end of the transmission shaft is provided with a rotating wheel, and the rotating wheel is provided with a gear, and the scale on the advance and retreat ruler is engaged with the gear on the rotating wheel.

The utility model has the advantages that: by using the insulator pin remover of the utility model, it can ensure timely replacement and maintenance of insulators with problems under electrified conditions. The replacement situation will cause power outages on the line, eliminate potential safety hazards on the line, improve work efficiency, and effectively reduce potential safety hazards on site.

Description of drawings:

Accompanying drawing is the structural representation of the utility model.

In the accompanying drawings, 1 is a pincer handle, 2 is a fixed card, 3 is a transmission shaft, 4 is an advance and retreat chi, 5 is a transmission wheel, and 6 is a fixed pin.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

A new type of insulator pin remover, which welds two fixing clips (2) on the pliers handle (1) of the original insulator pin remover, inserts the transmission shaft (3) into the fixing clips (2) and fixes them, and inserts and The retracting ruler (4) passes through the middle of the drive shaft (3), and the top end is fixed with the fixing pin (6) of the other pincer handle of the pin remover. Put the advancing and retracting ruler (4) on the operating rod of the insulator, and rotate the operating rod Drive the gear (5) on the rotating shaft (3) to rotate, and the rotation of the gear (5) engages the scale on the advance and retreat ruler (4), so that the advance and retreat ruler (4) moves horizontally so that the pliers handle (1) Close or separate, replace or repair the insulator when it is live, thus effectively avoiding the situation that the insulator (bowl head) cannot be replaced due to problems, causing power outage maintenance of the line, eliminating potential safety hazards of the line and improving work efficiency, effectively Reduce on-site safety hazards.
