Abstract
The utility model relates to a ground line hitching device used in a maintenance process of power distribution equipment, which comprises a movable frame. An expansion link capable of expanding vertically under electric operation or manual operation is installed on the frame. The whole expansion link can rotate freely or move back and forth under the electric or manual operation. An inserting hole for connecting with a ground line rod portion is arranged at the upper end of the expansion link. An L-shaped clamping groove is arranged on the hole wall of the inserting hole. An inserting and connection section capable of being matched with the inserting hole is arranged on a ground rod portion of the ground line. An axial bayonet lock is arranged on the outer wall of the inserting and connection section. The bayonet lock can perform linear movement along the upright section of the L-shaped clamping groove and perform circle motion along a horizontal section of the L-shaped clamping groove to enable the ground rod portion of the ground line to be capable of connecting with the upper end of the expansion rod in clamping mode. The ground line hitching device can finish hitching and separation of the ground line automatically, greatly improves efficiency and safety of maintenance work of power equipment, and is capable of ensuring reliability of grounding work.
Description
Technical field
