The invention provides stepping self-moving temporary support equipment and a support method thereof, and belongs to the technical field of coal mine underground support. The technical problems that existing support equipment is low in working efficiency, and the number of corollary equipment is reduced are solved. According to the solution, a plurality of temporary support equipment stretches across the upper portion of a heading machine and is sequentially arranged in the heading advancing direction; a top beam assembly comprises a first top beam and a second top beam; the head end and the tail end of the first top beam are hinged to one end of the second top beam through top beam connecting lug bases correspondingly; the other end of the second top beam is hinged to stand column assemblies through stand column connecting lug bases; the stand column assemblies on the two sides are oppositely arranged; and self-moving base components are arranged below the stand column assemblies. The temporary support equipment at the tail end can shorten stepping self-moving walking, is unfolded after moving to the heading face head-on, and temporarily supports a roadway roof newly cut by the heading machine in time, synchronous following of heading machine coal cutting footage advancing and support advancing is achieved, the support strength and stability are enhanced, and adaptability is higher.
Description
technical field [0001] The invention belongs to the technical field of roadway support in coal mines, and in particular relates to a stepping self-moving temporary support equipment and a support method thereof. Background technique [0002] In the continuous mining and filling coal mining process of coal mines, the form of "long wall layout, short wall mining" is adopted. The length of the coal mining face of the branch road is generally 80m. The level of mechanical temporary support device and excavation production efficiency, the self-moving temporary support device of straddle roadheader plays an important role. Common temporary support methods include: [0003] 1. The single hydraulic support is equipped with π-shaped metal hinged beams. This support method is labor-intensive, cannot be mechanized, has low efficiency, and the support area is small. It requires personnel to enter the empty roof area and the operation safety risk is great; [0004] 2. Forward probing be...
