AI Technical Summary

Technical Problem

During the flipping process, the gripper of the inspection robot is prone to loosening, which may cause it to lose its grip on the insulator cap and potentially fall off.

Method used

Design a gripper structure in which the first and second grippers are hinged side by side on the same bracket and rotate synchronously through a drive assembly. During gripping, the projections of the free ends of the grippers overlap. The connection stability is enhanced by a snap-fit ​​structure. The gripping force is uniformly transmitted by combining a motor module and a lead screw and nut transmission system.

Benefits of technology

It effectively prevents gaps from forming in the gripper when the gravitational acceleration changes, ensuring that the gripper can always hold the insulator tightly, preventing the robot from falling, and improving the stability and torsional resistance of the gripper.

Abstract

A gripper structure for insulator inspection includes a first gripper and a second gripper, which are hinged side-by-side to the same support. The support is equipped with a drive assembly, which is hinged to both the first and second grippers. The drive assembly is used to drive both grippers to rotate simultaneously. When both grippers are clamped together, the X-direction projections of the free ends of the first and second grippers overlap. This overlap increases the contact area and interaction force between the grippers, effectively preventing gaps from forming due to changes in gravitational acceleration, thus ensuring the gripper always holds the steel cap firmly and preventing the inspection robot from falling off the insulator.
