Execution mechanism of shakeproof hammer reset device for overhead lines

Abstract

The invention provides an execution mechanism of a shakeproof hammer reset device for overhead lines. The execution mechanism comprises a mechanism bottom plate, a one-degree-of-freedom moving platform in a horizontal direction, a pitching adjustment mechanism, an impact wrench feeding mechanism, an impact wrench and a camera, wherein the mechanism bottom plate is taken as a support of the whole mechanism, the lower end of the mechanism bottom plate is connected with a shakeproof hammer reset device body, the moving platform comprises two parallel linear sliding rails and a sliding table, the types of the two parallel linear sliding rails are same, a lead screw driving part is arranged between the sliding rails and is used for achieving horizontal movement of the sliding table, the pitching adjustment mechanism comprises a 90-degree corner gear box and a pair of four-bar mechanisms, the pair of four-bar mechanisms are arranged at the two sides of the gear box, the gear box is used for transferring power from a motor in a vertical direction, the second degree of freedom is achieved through adjusting the angle of a workbench by the four-bar mechanisms, the impact wrench feeding mechanism comprises a one-degree-of-freedom sliding table, a gear rack transmission mechanism and a sensor, the third degree of freedom of the impact wrench is achieved through adjustment along a direction of a screwed bolt, the impact wrench and the camera are arranged at the tail end, and a shakeproof hammer bolt can be positioned and fastened through the reset device by the impact wrench. The execution mechanism is simple to abut and is high in reliability, manual operation can be substituted, and the execution mechanism is safe and reliable and is simple to operate.

Description

technical field [0001] The invention provides an actuator for a resetter of an anti-vibration hammer of an overhead line to replace manual work and solve the maintenance problem of "slipping" of the anti-vibration hammer of a high-voltage line. Background technique [0002] Since the overhead transmission line is erected on the pole tower of tens of meters in the field for a long time, it is susceptible to vibration due to the influence of the wind. Long-term strong vibration will cause fatigue damage to the material of the overhead transmission line, which will lead to broken strands and wires. In order to prevent or reduce the damage caused by the vibration of the overhead ground wire, a common method is to install a shockproof hammer outside the suspension point of the overhead ground wire. If the anti-vibration hammer is not tightened when the bolt is installed on the overhead ground line or is affected by the natural environment during operation, the anti-vibration hamm...

AI Technical Summary

Problems solved by technology

The robot technology is relatively advanced, the structure is relatively complex, and the functions are relatively complete.

However, the robot is bulky, too heavy, and the cost is very high, which is a difficult burden for ordinary power supply companies

[0005] On the other hand, the robots developed by most researchers have multiple functions, but the completion of individual functions is not ideal, and the degree of modularization of the mechanism is not high, which is why many robots cannot be widely used

As for the execution module for the reset of the anti-vibration hammer, there is no relevant mechanism developed yet.
