Reset unit for correcting displacement of damper on electric transmission line

Abstract

The invention discloses a reset unit for correcting the displacement of a damper on an electric transmission line. The reset unit comprises a shell, wherein a laser range finder and a striker are arranged at the front end of the shell, a strip-shaped opening is formed in the shell in the length direction, and the shell is hung on a power transmission line through the strip-shaped opening to enable the power transmission line to pass through the interior of the shell; traveling wheels are arranged in the shell and located above the power transmission line, and a locking wheel capable of moving near the power transmission line is arranged in the shell and located below the power transmission line; a signal transceiver and a controller are also arranged inside the shell, the controller is connected with the signal transceiver, the laser range finder and the striker, movement of the shell and working of the striker are controlled by a remote controller matched with the signal transceiver, and the striker can reciprocate along the power transmission line to strike the damper constantly so as to make the damper reset. The whole reset unit is controlled remotely to move, correction and operation are easy, operability is high, and safety is high.

Description

【Technical field】 [0001] The invention relates to a reset device, in particular to a reset machine capable of correcting the displacement of an anti-vibration hammer of a power transmission line. 【Background technique】 [0002] There are many vibration damping devices selected in the power system, and a component installed on the wire designed to prevent breeze vibration is widely used in the actual erection of transmission lines. In principle, the anti-vibration hammer consists of a short steel strand with a heavy hammer installed at both ends, and a splint that can be hung on the wire is installed in the middle. When the wire vibrates, the steel strand of the anti-vibration hammer The two ends of the wire are constantly shaking up and down, so as to consume the vibration energy transmitted from the wire, thereby reducing the amplitude of the wire, so as to reduce the harm caused by the breeze vibration. [0003] After running for a period of time, the anti-vibration hamme...

AI Technical Summary

Problems solved by technology

[0004] One is that the grip strength of the anti-vibration hammer clamp cannot meet the needs of the line erection project

Second, the anti-loosening measures of the anti-vibration hammer clamp cannot effectively compensate for the creep of the wire

The third is that the construction personnel failed to reach the maximum pressure when tightening the bolts

Fourth, the design of the center of gravity of the two ears of the anti-vibration hammer is unreasonable and its own weight leads to a slip to the center of the gear during the vibration process.

Fifth, the initial elongation of the wire and the inconsistent thermal expansion coefficient of the wire and the anti-vibration hammer lead to changes in the grip of the wire clamp

[0007] However, the above improvement measures can only prevent the displacement of the anti-vibration hammer to a certain extent, but after the anti-vibration hammer is installed, in case of displacement, there is currently no effective means to assist the reset of the anti-vibration hammer
