Manipulator for damper bolt dismounting

Abstract

The invention discloses a manipulator for damper bolt dismounting. The manipulator comprises a damper bolt automatic loading / unloading module and a damper clamping and positioning module; the damper clamping and positioning module comprises an arched or L-shaped rocker arm, an electric push rod for clamping jaws arranged at the lower part of the rocker arm, two clamping jaws symmetrically arranged left and right, and a positioning platform; the electric push rod is connected to the rocker arm; one end of one clamping jaw in the two clamping jaws is hinged to a push rod of the electric push rod; the clamping jaw connected with the electric push rod drives the other clamping jaw to perform a closing or opening motion through a gear; the positioning platform for supporting a damper is arranged below the clamping jaws; and the damper bolt automatic loading / unloading module comprises an arched or L-shaped rocker arm, an electric slide table, a sleeve shaft, an extension sleeve and a fixed frame. The manipulator for damper bolt dismounting can realize automatic electrified installation and disassembly of the damper, prevents manual equipotential operation, greatly improves the working safety, and reduces the labor intensity.

Description

technical field [0001] The invention relates to a device for disassembling and assembling anti-vibration hammer bolts, in particular to a manipulator for disassembling and assembling anti-vibration hammer bolts. Background technique [0002] When the overhead transmission line is subjected to a stable and moderate breeze, more than one airflow vortex with a certain frequency that alternates up and down will be generated on the leeward side of the ground wire. When the alternating frequency of the airflow vortex is equal to the natural frequency of the overhead wire, resonance will be generated in the vertical plane, which will cause the vibration of the overhead wire. The breeze vibration of the overhead line is a harmful vibration that often occurs, which poses a great threat to the safe operation of the line. Vibration causes "fatigue" phenomenon in the overhead line, causing strand breakage or even wire breakage in the overhead line. In order to prevent the overhead lin...

AI Technical Summary

Problems solved by technology

The equipotential operation is relatively dangerous, the labor intensity of the operators is extremely high, the quality of the operators is high, and the operation risk is high; the second is that some compact towers and wires are arranged vertically or crossed , there is not enough space for live work to meet the work requirements, and a power outage is required

[0006] (2) The power outage operation also has the disadvantages of high labor intensity and high operation risk

In addition, if the power outage is dealt with, first, it will affect the reliability of power supply, and second, because the power outage has been included in the planned management, the suddenness and timeliness of defect handling will conflict with the planning of the power outage, and it is often impossible to deal with anti-vibration in time Hammer defect, there is a risk that the defect will continue to develop and endanger the safe operation of the line

[0007] In addition, the ground wire fittings will have defects such as bolt looseness, nut looseness, and nut drop-off due to breeze vibration and other effects. The fittings should be replaced in time. Serious accidents such as disconnection
