Description

Technical Field

[0001] The utility model relates to the technical field of battery monorail crane locomotive power replacement, in particular to a battery monorail crane locomotive power replacement system. Background Art

[0002] Battery monorail crane is a special ground rail coal mine auxiliary transportation equipment running on the roof of the tunnel. It is suitable for underground material and personnel transportation operations in coal mines. The locomotive is powered by batteries and has the advantages of flexibility, less impact from bottom plate deformation, low operating noise, and green environmental protection. With the increasing requirements for diesel engine monorail exhaust emissions in coal mine safety production, mines are gradually using battery monorail cranes to replace diesel engine monorail cranes. The proportion of battery monorail cranes in coal mine production is gradually increasing. As a result, the endurance of battery monorail cranes cannot meet the expected requirements during use, so locomotives are generally equipped with 1-2 sets of backup batteries.

[0003] The current technical solution is to use ground rails and unpowered trolleys. The battery monorail is lifted to the charging position, and the lifting beam is lowered to the battery onto the unpowered trolley. The trolley needs to be pushed along the ground rail to the charging position manually. This method pushes the battery trolley with a large load capacity, which increases the labor intensity of the workers. At the same time, the efficiency is low, and the speed of manual pushing is difficult to control. When the object is pushed too fast, the momentum is large, which poses a great safety hazard. Therefore, a battery monorail crane locomotive battery replacement system is proposed. Utility Model Content
