Description

Technical Field

[0001] The utility model relates to the technical field of insulator calibration, in particular to a power insulator calibration device. Background Art

[0002] In power lines, the most widely used conductor support equipment is the power insulator, which has various forms such as magnetic column type and composite type. Generally, the internal structure is metal and the external structure is ceramic or synthetic material. However, with the long-term operation of the line, especially the widespread use of insulated wires, the pressure and tension on the insulators are getting greater and greater. When the wires dance for a long time, the poles tilt, and tree barriers are hung, the insulator tilt problem often occurs. The main treatment method is to replace the insulators. The cost of replacing insulators is high. When replacing, the line needs to be shut down for maintenance, which increases the cost of maintenance.

[0003] At present, in the prior art, for example, Chinese patent with announcement number CN2174052 discloses a power insulator calibration device, which fixes the metal bottom rod of the insulator by rotating the threaded guide rail and sliding the card to the left on the outside of the threaded guide rail. Then, by prying the device up and down, the bent and deformed metal bottom rod of the insulator is restored to verticality. The insulator can be restored to verticality without replacing the insulator, which reduces the cost of replacing the insulator. When repairing the tilt of the insulator, it can be completed without shutting down the line, which reduces the maintenance cost.

[0004] However, the device cannot cope with the simultaneous tilting of multiple sets of insulator devices, and it is impossible to calibrate multiple sets of insulator devices when there are only a few staff members. In addition, the insulators are at high altitudes and cannot protect themselves when facing high-speed collisions with debris or strong winds, which increases maintenance costs and reduces work efficiency. In view of this, we propose a power insulator calibration device. Utility Model Content

When the insulating handle 13 is rotated, the insulating handle 13 drives the threaded rod 9 to rotate upward, and the threaded rod 9 drives the connecting seat 10 to move upward at the same time. When the connecting seat 10 moves upward, the card joint 11 fixedly connected on its outer wall will be snapped into the card groove 12 fixedly connected on the outer wall at the bottom end of the connecting rod 5 for fixing.

[0031] A telescopic column 14 is fixedly connected to the outer wall of the fixed base 2, and a telescopic column 14 is also fixedly connected to the outer wall of the bottom end of the connecting rod 5 at the end away from the fixed base 2. Telescopic springs 15 are fixedly connected to the outer walls of the two groups of telescopic columns 14. When the insulator body 3 is hit by a strong wind, the insulator body 3 swings left and right. At this time, the telescopic spring 15 is squeezed downward by the insulator body 3 and compressed. The telescopic spring 15 has a rebound force, which will drive the insulator body 3 to rebound upward, so that the insulator returns to its original position.

[0032] The connecting rod 5 is fixedly connected to a stabilizer 6 at one end away from the center rotator 4.

When the insulator body 3 is impacted by a strong wind, the insulator body 3 swings left and right. At this time, the telescopic spring 15 is squeezed downward by the insulator body 3 and compressed, and the telescopic spring 15 has the power of rebounding, which will drive the insulator body 3 to rebound upward, so that the insulator returns to its original position. If it is about to encounter a stronger strong wind attack, the insulating handle 13 is rotated, and the insulating handle 13 drives the threaded rod 9 to rotate upward. At this time, the threaded rod 9 drives the connecting seat 10 to move upward at the same time.
