Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a temporary support device for coal mining. Background Technology

[0002] During coal mining, the inner walls of the roadway need to be supported and protected. Existing temporary support equipment is mostly constructed of plate-like structures, whose support range is too fixed and difficult to adapt to actual conditions, thus limiting its use. Therefore, designing a temporary support device for coal mining is crucial. For example, the temporary support device for coal mining roadways with authorization announcement number CN222254011U includes multiple protective supports, a carrier plate, and two fixing mechanisms. The end face of the carrier plate has multiple square grooves, and both sides of the carrier plate have threaded grooves and multiple fixing grooves, with the fixing grooves penetrating the square grooves. Two roller mechanisms are provided at both ends of the carrier plate. Multiple hydraulic jacks are provided below the carrier plate, and support plates are provided at the output ends of the multiple hydraulic jacks. Two fixing mechanisms are symmetrically arranged on both sides of the carrier plate. Each fixing mechanism includes multiple fixing rods, screws, and connecting plates. A rotating ring is provided on the screw, and a rotating disk is provided at one end of the screw. The middle of the connecting plate has a rotating groove. Through the arrangement of multiple fixing rods and the connecting plate, multiple protective brackets can be fixed at the same time, thereby enabling quick assembly and disassembly of the protective brackets. At the same time, the connecting plate is fixed by the screws, thereby improving the fixing effect of the fixing rods on the protective brackets.
