Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for the installation of fully mechanized mining support, specifically to a hanging plate assembly for installing circuit breakers on top support. Background Technology

[0002] Fully mechanized top support is a large-scale machine used in mines to provide support for the roof of roadways. Its operation is mostly powered by electrically controlled hydraulic props. Therefore, each fully mechanized support unit needs to have an independent circuit breaker installed to achieve effective circuit control. However, currently, the circuit breakers of most fully mechanized support equipment are installed at the position between the two hydraulic props on the underside of the rear beam. Furthermore, due to the small size and large weight of these circuit breakers, there are significant obstacles to their installation. Because of their small size, they cannot be moved by multiple people working together, and their large weight and relatively confined operating environment further increase the installation difficulty. This is the main purpose of this invention. Utility Model Content
