Transmission Line Insulator String Operation Robot Based on Gear Rack Meshing Mechanism
Insulator flashover is one of the most common accidents that affect the reliability of transmission lines.In order to ensure the normal operation of transmission lines,it is necessary to regularly clean the insulators.Due to the inconvenience,low efficiency and low safety of manual operation on towers,the use of work robots is particularly important.In response to the problems of low work efficiency and poor job stability of existing robots,this article proposes a lightweight tension insulator string operation robot based on the gear rack meshing mechanism.Based on the workingenvironment of transmission lines and theoretical analysis,a new type of driving wheel and passive guide plate structure is proposed.Furthermore,the influence of sag and lateral wind force is considered in the simulation.Finally,a stability test is conducted on the robot's movement on the insulator string.The experiments show that under normal operation of the power grid,operators can remotely control the work robot to accurately and stably reach the designated work position.This not only ensures the normal operation of the power grid,improves work efficiency,but also protects the safety of workers.
