Asymmetric hydraulic supports for pseudo inclined mining in steeply dipping seam

An asymmetric hydraulic support for pseudo inclined mining in steeply dipping seam, wherein the asymmetric hydraulic support includes a top mechanism, a bottom mechanism, a telescopic mechanism, and a connecting mechanism;

• wherein
• the top mechanism and the bottom mechanism are disposed in parallel to each other, the top mechanism includes a top plate in a shape of a parallelogram, the bottom mechanism includes a bottom plate in a shape of a parallelogram, and a projection of the top mechanism on a working surface and a projection of the bottom mechanism on the working surface are two parallelograms, and a sum of an acute angle of each of the two parallelograms and a steeply dipping angle in pseudo inclined mining is 90°;
• the telescopic mechanism is provided between the top mechanism and the bottom mechanism, and two ends of the telescopic mechanism are rotationally connected to the top mechanism and the bottom mechanism, respectively;
• the connecting mechanism includes a telescopic structure and two sets of connecting structures, the two sets of connecting structures include a first connecting structure and a second connecting structure;
• one end of each of the first connecting structure and the second connecting structure is hinged by a first articulating shaft, and a central axis of the first articulating shaft is located in a middle of the top mechanism and the bottom mechanism, and the other end of the each of the first connecting structure and the second connecting structure is hinged to a first side of the top mechanism and a first side of the bottom mechanism, respectively, by a second articulating shaft;
• each of the two sets of connecting structures includes a connecting plate and two sets of shelter assemblies, each set of the two sets of shelter assemblies includes a baffle plate and a plurality of inserting components;
• the plurality of inserting components is arranged on one side of the baffle plate;
• the two sets of shelter assemblies are arranged on a surface of the connecting plate, two baffle plates in the two sets of shelter assemblies are arranged on two sides of the first articulating shaft, and a side of one of the two baffle plates on which the inserting components are set is adjacent to the side of the other of the two baffle plates on which the inserting components are set, so that when the two sets of the connecting structures are rotated relative to each other, the two baffle plates move in a direction of the center axis of the first direction, to make the two baffle plates and the connecting plate have no gaps and a sum of a width of the connecting plate and widths of the two baffle plates along a direction of the center axis of the first articulating shaft is adapted to a width of the top mechanism;
• and
• one end of the telescoping structure is hinged to the first connecting structure which is hinged to the top mechanism, the other end of the telescoping structure is hinged to the bottom mechanism, and a center point of the hinging is coplanar with a vertical bisector of a projection of an edge of the first side of the bottom mechanism on the working surface.
