Description

Reset device of anti-vibration hammer for overhead ground wire of transmission line

technical field

The invention belongs to electric construction equipment, in particular to an anti-vibration hammer reset device for overhead ground wires of power transmission lines.

Background technique

The transmission line runs in the field all the year round, and is affected by the natural environment and meteorological conditions for a long time. The anti-vibration hammer of the overhead ground wire of the transmission line has more chances of moving defects. When such defects occur, the anti-vibration hammer is out of its own installation position, Rolling in the direction of the center of the gear span, when it is found that it has been out of position for several meters or even hundreds of meters, which brings considerable difficulty to the maintenance work. If the power failure is dealt with, it will also affect the reliability of the line and bring economic losses. Wire removal will increase the workload. Because the anti-extension vibrating hammer is out of its own position, the anti-vibration protection effect on the overhead ground wire will be lost. If such defects are not dealt with in time, the overhead ground wire will be too large due to vibration and wear. And the occurrence of broken strands or even broken lines will cause transmission line accidents and bring greater losses.

Contents of the invention

The object of the present invention is to overcome the above-mentioned technical deficiencies, and provide a reset device for anti-vibration hammers of overhead ground wires of transmission lines that has a simple structure, can ensure safe and stable operation of transmission lines, and is convenient for defect elimination.

The technical solution adopted by the present invention to solve the technical problem is: the anti-vibration hammer reset device for the overhead ground wire of the transmission line includes a steering pulley, a riding pulley, an insulating pulley, an insulating pulley two, an insulating pulley three, and an insulating pulley four. The feature is that two riding pulleys arranged in front and back are installed on the pulley mounting frame, and the riding pulleys are respectively mounted on the overhead ground line. There is a reset baffle in the shape of a few characters. An insulating rope hanging ring is installed on the left end of the traction link. One end of the insulating rope is connected to the insulating rope hanging ring. The other end of the insulating pulling rope is wrapped around the steering pulley and hangs down. , the steering pulley is fixed on the transmission pole tower, the second insulating pull rope is fixed under the traction link on the left side of the pulley mounting frame, the third insulating pulling rope is fixed under the pulley mounting frame, and the insulating pulling rope 4 is fixed on the right side of the pulley mounting frame Below the drawbar.

The beneficial effects of the present invention are: the reset device of the anti-vibration hammer for the overhead ground wire of the transmission line has a simple structure, can reduce the difficulty of eliminating the defect of the anti-vibration hammer of the overhead ground wire, reduce the workload of the maintenance personnel, and ensure the safe and stable operation of the transmission line. It saves time and effort in eliminating defects.

detailed description

Embodiment, with reference to accompanying drawings 1 and 2, the pulley mounting frame 4 of the anti-vibration hammer reset device for the overhead ground wire of the transmission line is equipped with two riding pulleys 6 arranged in front and rear, and the riding pulleys 6 are respectively mounted on the overhead ground wire 7 , the overhead ground wire is erected on the power transmission tower through the suspension clamp 1 and the supporting wire clamp 2, and the anti-vibration hammer 9 and the hammer head 8 are just hung on the overhead ground wire 7. The pulley mounting bracket 4 and the traction link 10 are hinged through the connecting pin 5, and the right end of the traction link 10 is provided with a reset baffle 10-1 in the shape of a zigzag, and the reset baffle 10-1 is placed on the anti-vibration On the overhead ground wire 7 on the right side of the hammerhead 9. An insulating rope hanging ring 3 is housed on the left end of traction pull bar 10, and insulating rope hanging ring 3 connects an end of insulating stay rope one 12, and the other end of insulating stay rope one 12 hangs down around steering pulley 11, and steering pulley 11 is fixed on On the transmission tower.
