Powered roof support section
专利摘要:
The invention relates to an advance mechanism for a roof support unit to be used in a longwall face of a mineral mining working. The advance mechanism comprises a hydraulic advance ram and guide means constituted by a guide rod means and a guide rail. One end of the guide rod means is attached to a conveyor extending along the longwall face, the other end of the guide rod means being attached to a guide element. The guide rail extends slidably through a guide aperture in the guide element and is pivotally attached to the floor sill of the roof support unit for pivotal movement in a vertical plane perpendicular to the longwall face. The hydraulic advance ram is attached to the guide element and acts on a member fixed to the floor sill. 公开号:SU927128A4 申请号:SU782668753 申请日:1978-10-04 公开日:1982-05-07 发明作者:Плевак Любомир;Додт Юрген 申请人:Геверкшафт Эйзенхютте Вестфалия(Фирма); IPC主号:
专利说明:
I The invention relates to underground mining, namely, to structures of powered roof supports. Under main patent No. 5, a mechanized support section is known, comprising a base made of two beams interconnected by a cross member, hydroresistance, a fence which is connected to the bottom by means of traverses, and a hydraulic jack of movement connected at one end with a guide. by ski. This section provides for the installation of base beams with IS possibility of vertical movement, for which the cross member is hinged to the base beams, the hydraulic end jack 20 of the shifter is attached to it with a free end through a swivel support, and hydroracks 1 are installed on each base beam. With a vertical displacement of one of the base beams relative to the second the swarm of the guide skid rotates, as a result of which it is subjected to heavy loads, which limit the efficiency of the section lining. The purpose of the invention is to increase the efficiency of the lining section operation on seams with complex hypsometry. The goal is achieved by the fact that one of the base beams in the rear part is provided with a guide rod pivotally connected to it by means of a horizontal axis, mounted parallel to the ski guide, and the coupling of the hydraulic jack with the ski guide is made with a hole in which movement set guide rod FIG. 1 shows the lining section, side view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. 2 The lining section includes a base made of two beams 1, which are interconnected by a cross bar 2, supporting the top to the hydroracks 3, a hydraulic sleeper k of movement, connected by one end to the cross bar 2, and the other end to the guide ski 5 The rear part has a guide rod 7 pivotally connected by means of a horizontal axis 6 and parallel to the guide ski 5, and the link of the travel hydraulic jack J to the guide ski 5 has an opening 8 for mounting the guide rod 7 in it. ski guide 5 and guide rod 7 are mounted with relative movement. The work of the lining section is carried out as follows. . When the cylinder of cylinder is moved in and around, the downhole conveyor moves in the direction of the bottom, and the cylinder is supported through cross-piece 2 on the support sections. When moving the cylinder, moving the support section free of pressure, we will adopt the cylinder resting on the ski guide. four 5, associated with a downhole conveyor. In this case, the rear end of the guide ski 5 is moved along the guide rod 7. In case of meeting with the ground support section, one beam relative to the other can move without causing the guide ski 5 to turn. invention formula The mechanized support section according to patent No., characterized in that, in order to increase its efficiency on formations with complex hypsometry, one of the base beams in the rear part is equipped with a guide rod pivotally connected to us through a horizontal axis the ski guide, and the coupling of the hydrojack of movement with the ski guide is made with a hole in which the guide rod is installed with the possibility of longitudinal movement. Sources of information taken into account in the examination 1. USSR patent If, cl. E 21 D 23/00, 1976 (prototype).
