Abstract

The invention discloses a grounding handcart locking device for locking a grounding handcart and aims to provide a grounding handcart locking device for compulsively locking a grounding handcart stored inside a switch cabinet, and then the problem that potential danger is caused if the ground grounding handcart inside the switch cabinet is operated randomly by an operator can be avoided. The grounding handcart locking device comprises a positioning pre-locking mechanism and a locking mechanism, wherein the positioning pre-locking mechanism comprises a left horizontal guide sleeve and a right horizontal guide sleeve which are coaxially arranged on a bottom rack of a grounding handcart, a left positioning rod which is arranged inside the left horizontal guide sleeve in a sliding manner, a left positioning hole which is formed in the inner side surface of a switch cabinet, a right positioning rod which is arranged inside the right horizontal guide sleeve in the sliding manner, and a rightpositioning hole which is formed in the inner side surface of the switch cabinet; the locking mechanism comprises a left operation rod locking buckle which is matched with a left operation rod, a right operation rod locking buckle which is matched with a right operation rod, and a locking rod which is used for connecting the left operation rod locking buckle and the right operation rod locking buckle.

Description

technical field [0001] The invention relates to a locking device, in particular to a grounding handcart locking device for locking a grounding handcart. Background technique [0002] With the continuous update and application of substation equipment in the power system, a large number of grounding handcarts have been used in the substations of the power system. Although the application of the grounding handcart facilitates the actual operation, in actual use, since the grounding handcart cannot be locked in the switch cabinet, the grounding handcart stored in the switch cabinet can be operated at will, which is not only unfavorable for the grounding handcart Standardized management, and prone to misoperation, resulting in potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a grounding trolley that can be stored in the switch cabinet forcibly locked in the switch cabi...
