1results about How to "Avoid tearing off" patented technology

This utility model relates to a temporary support device for roadways in mining engineering, belonging to the field of mining engineering technology. The temporary support device for roadways in mining engineering includes: a support mechanism, comprising a base, a mounting block, and a lifting plate; two sets of lifting components are provided on the upper surface of the base; a detachable mechanism, comprising a detachable plate, a connecting plate, and a connecting threaded rod; the connecting plate is fixedly disposed on both sides of the detachable plate, and the detachable plate is threadedly connected to the lifting plate via the connecting threaded rod; and an auxiliary mechanism, comprising a connecting block, an extension column, an auxiliary top plate, and a drive component that drives the auxiliary top plate to rise and fall to support the roadway. When the detachable plate adheres to the roadway, the drive component drives the extension column to rise, thereby driving the auxiliary top plate to support the roadway on both sides of the detachable plate. At this time, the lifting component drives the lifting plate to fall, thus supporting the roadway while simultaneously lowering the detachable plate, thereby preventing the entire arch on both sides of the detachable plate from being torn off during attempts to disassemble it.
