Shakeproof hammer reset device

Abstract

The invention discloses a shakeproof hammer reset device. The shakeproof hammer reset device comprises a reset body, a second impactor and a first impactor, wherein the second impactor and the first impactor are vertically arranged, a sleeve element is fixedly connected to the bottom surface of the reset body and is used for sleeving a traction object, at least two frames are arranged in parallel on the top surface of the reset body in a left-right way, each frame is connected with a moving assembly, an accommodating region is formed between the moving assembly and the reset body and is used for accommodating an overhead line, the right end of the first impactor and the right end of the second impactor are arranged in the same vertical plane, the frames are symmetrically arranged at the two sides of the same vertical plane jointly formed by the axial line of the sleeve element, the moving directions of the moving assemblies, the axial line of the first impactor, the axial line of the second impactor and the axial line of the overhead line, so that the impact forces from the shakeproof hammer reset device relative to the two sides of the overhead line are more uniform when a shakeproof hammer is reset, the overhead line is prevented from being damaged due to fierce friction with the shakeproof hammer, and the service lifetime of the overhead line is prolonged.

Description

technical field [0001] The present invention relates to maintenance tools for power transmission lines, and more particularly, it relates to a reset device for anti-vibration hammers. Background technique [0002] The overhead lines often vibrate or dance due to the influence of the wind. The vibration frequency of the overhead line is high and the amplitude is small, so that the overhead line is repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands or broken lines; the frequency of galloping is very low but the amplitude is large, which is easy Cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burning wires. In order to reduce the vibration and galloping of the overhead line, an anti-vibration hammer is added to the suspension point of the overhead line to absorb or weaken the energy of vibration or galloping, and change the swing frequency of the overhead line. However, ...

AI Technical Summary

Problems solved by technology

Although the anti-vibration hammer resetter can reset the anti-vibration hammer, it has the following defects: because the wheel surface of the pulley is in contact with the peripheral surface of the overhead wire, that is, the contact between the surfaces, the contact area is relatively large, And then produce bigger contact resistance, make very strenuously when dragging rope, and can not produce higher speed, so the momentum of this anti-vibration hammer reset device is very little (momentum is equal to speed multiplied by quality), to the anti-vibration hammer The impact force is small, so the reset speed of the anti-vibration hammer is small; in addition, when the anti-vibration hammer reset device is subjected to uneven drag force, the pulley will jump on the overhead line, so that the anti-vibration hammer reset device cannot be stably Push the anti-vibration hammer to reset

[0006] However, according to the content of the comparative document 1, it can be seen that the impactor can only be used to withstand a part of the wire clip, so when the anti-vibration hammer is pushed, the anti-vibration hammer will be skewed and unable to move; clamp to push the anti-vibration hammer, the surface of the overhead ground wire will be worn by the anti-vibration hammer
