    • 专利摘要:
    A mine support assembly is composed of separate floor-engaging sills each supporting one or more telescopic props and a goaf shield pivotably connected to a roof cap. The props can be extended or retracted to raise or lower the roof cap. The shield is divided into a common upper section and lower parts each pivotably connected to the upper section and to a respective associated one of the floor sills. Levers are pivotably connected between the sills and the upper section of the goaf shield and serve with the lower shield parts as a guide means ensuring the roof cap is raised or lowered without appreciable horizontal displacement. The floor sills and lower shield parts are respectively spaced apart and a shifting ram is connected to the floor sills via a transverse yoke pivotably connected to the forward end regions of the sills. The ram is located in a space between the sills and is connected at its rear end to a cross piece guided in the sills and connected to bars which extend along the space between the sills to form a cantilever beam connected directly or indirectly to a longwall conveyor.

    专利说明:

    The invention relates to underground mining, namely, mechanized fortifications for stope faces. The mechanized lining sections are known, including both the upper and the base, made in the form of beams, while they are connected to the uprights by means of a flat spring or a system of flat springs 1. they do not provide independent shifting of the lining section. ... The closest solution to the technical essence and the achieved result is the mechanized crepe section, which includes the foundation, made of two beams, interconnected transverse, hydraulic, fencing, which is connected with the base by means of traverse connected at one end with a guide lion 2 The disadvantage of this support is insufficient adaptation; The bridge of the lining sections to the unevenness of the soil and the impossibility of independent movement of the lining sections. The aim of the invention is to increase the adaptability of the section to soil irregularities and. the possibility of independent advancing sections lining. The goal is achieved by the fact that the base beams are mounted with the possibility of vertical movement, for which the cross member is connected to the base beams. FIG. I depicts a lining section, a general view; ca fig. 2 - base of the lining section without. fences; in fig. 3 is a view along arrow A in FIG. 1. The mechanized support section consists of a top 1, a fence 2, a base 3, made of two beams and connected by a cross member 4, hydraulic posts 5. The fence is connected to the base by means of cross-arms b. The hydraulic slide of the movement 7 is connected with one end to the guide ski 8, and the other is fixed by means of a pivot bearing 9 on a cross member, which is connected by a hinge 10
    with beams, which allows the beams of the base to move relative to each other in the vertical direction. Hydraulically 5 mounted on each bgshke. The ski guide 8 is connected to the conveyor 11.
    The work of the lining section is carried out as follows. . - - jjpjj gdgJ,., s „„ J, Shch5,: the hydrant jack is moved and 7. the ped moves towards the zaeZo, and the cylinder rests through cross member 4 on the support section. When the cylinder is pushed in, the support section is pushed free of pressure, and the cylinder rests on the guide ski 8 connected to the bottomhole conveyor.
    In case of meeting with the support section of the soil unevenness, one beam relative to the other can be displaced, since they are connected by a transverse 4, which is fixed pivotally.
