Description

Fixed self-locking heel block

technical field

The utility model relates to a self-locking pulley, which belongs to the field of inspection and maintenance of power transmission lines.

Background technique

In order to ensure the normal operation of the transmission lines in the power grid, it is necessary to carry out live inspection and maintenance on the transmission lines. Live work is a defect treatment method adopted to improve line operation level, reduce power outage time, and improve line availability factor. At present, the methods used to enter the equipotential on the tension tower include flat ladder entry and soft ladder entry. The process of entering the flat ladder is cumbersome. When the soft ladder enters, it is necessary to use the insulating rope to pull the soft ladder and hang it on the wire. At present, the insulating rope when the soft ladder enters is generally hung on the wire by throwing it, and then used to lift the ladder. The method wears the insulating rope more seriously. In order to solve this problem, a simple tool for entering the equipotential on the strain tower is specially developed.

Contents of the invention

The purpose of this utility model is to provide a fixed self-locking heel block to solve the problem that when the existing tension tower enters the equipotential, the use of a soft ladder to enter the insulating rope is very serious, the loss is large, and the cost is high. There is a certain degree of difficulty in hanging insulating ropes.

The scheme of the present utility model is as follows: the fixed self-locking bucket tackle includes self-locking metal plate, pulley, pulley hanger, U-shaped groove plate and slider, the pulley is rotated and arranged on the pulley hanger, and the upper end of the pulley hanger is fixedly arranged On the outside of one side wall of the U-shaped groove plate, a slider is fixedly arranged at the notch of the U-shaped groove plate on the other side wall of the U-shaped groove plate, or is located on the other side wall of the U-shaped groove plate in the U-shaped groove. The notch of the plate is fixed with a slider positioning plate, the slider is fixed on the slider positioning plate, a chute is opened on the self-locking metal plate, the slider is slidably set on the chute, and the self-locking metal plate passes through the slider The relative sliding in the chute realizes the opening and closing of the notch of the U-shaped groove plate.

Preferably, the chute is a bar-shaped hole opened on the self-locking metal plate, one end of the slider passes through the chute, and a limit block is fixedly arranged on one end of the slider passing through the chute, and the self-locking metal The plate is clamped between the limiting block and the U-shaped groove plate through the limiting block.

Preferably, the slider is a threaded rod structure, and the limit block is a nut structure matched with the external thread of the slider.

Preferably, on the other side wall of the U-shaped groove plate, a slider positioning plate is fixedly arranged at the notch of the U-shaped groove plate, and a second slider is also fixedly arranged on the slider positioning plate, and the second slider is also slidably arranged On the chute of the self-locking metal plate.

Preferably, the slider positioning plate is perpendicular to the side wall of the U-shaped groove plate.

Preferably, the line connecting the fixed ends of the slider and the second slider is perpendicular to the side plate of the U-shaped groove plate.

Preferably, the upper end of the self-locking metal plate is provided with a suspension ring structure.

Compared with the prior art, the utility model has the main advantage that the insulating rope is bypassed by the pulley, and the U-shaped groove plate is directly hung on the wire by the operating rod. When the operating rod is removed, the self-locking metal plate can automatically lock due to its own gravity. Close the notch of the U-shaped channel plate to prevent the U-shaped channel plate from falling off from the wire, and then lift the ladder through the insulating rope wound on the pulley to realize the entry of the soft ladder, which greatly reduces the wear of the insulating rope. At the same time, the block has a simple structure and is easy to use. It can be made by using only some scraps in the factory, and the cost is very low. It has been used in the transmission operation and maintenance branch of Guizhou Power Grid Corporation for a period of time, and the actual use effect is very good.
