Embodiment Construction
[0014] Below in conjunction with embodiment the present invention is further described.
[0015] Such as figure 1 , figure 2 A special support for safety exits in coal mining face is shown, which includes a load-bearing beam at the upper part and a base at the lower part, a hydraulic load-bearing column is connected between the load-bearing beam and the base, and the load-bearing beam includes two The load-bearing side beams 1 have a middle beam 12 between the two load-bearing side beams 1; four beam boxes 3 are welded on the lower part of the middle beam 12, and two cross beams 4 with opposite directions and staggered arrangements are arranged side by side in the beam box 3. The beam can be a back-shaped steel beam, with a partition between the two beams, one end of the beam is slidably connected to the beam box, and the other end is fixed on the load-bearing side beam 1; in the two beam boxes 3 in the middle of the middle beam 12, the beam 4 is equipped with a width adjus...

The invention discloses a bracket special for a safety exit of a coal face, belonging to the technical field of coal mine support equipment. The bracket comprises a bearing side beam, a middle beam, a hydraulic bearing column and a base, wherein a plurality of crossbeam boxes are fixed at the lower part of the middle beam, two crossbeams in opposite directions are installed in the crossbeam boxesin juxtaposition, one end of the crossbeam is slidably connected with the crossbeam boxes, and the other end is fixed on the bearing side beam; a width-adjusting oil cylinder is installed in the crossbeam; the bearing side beam is provided with an upper chute, the lower part of the base is provided with a lower chute; a movable top beam is installed in the upper chute and is internally provided with an upper traveling cylinder; the lower part of the movable top beam is connected with an auxiliary hydraulic column, the auxiliary hydraulic column is connected with a movable base beam arranged in the lower chute, and the movable base beam is internally provided with a lower traveling cylinder. The invention has adjustable total width, strong adaptability, convenient operation, safety and stability, can travel by self-shift in the support state, is manufactured easily and saves cost.
Description
technical field [0001] The invention relates to coal mine support equipment, in particular to a special hydraulic support for two safety exits of a coal mining face, which belongs to the technical field of coal mine equipment. Background technique [0002] The currently known support equipment for two safety exits in the coal mining face generally adopts a hydraulic unit and a hinged top beam or a lace steel beam for support. The support strength is poor, and the support quality is unstable. In the process of advancing the coal mining face, there are disadvantages such as large support workload, large material consumption, time-consuming, and poor safety, which seriously restrict the safe production of coal mines. Work. Especially in the current coal mining technology, the degree of mechanization is getting higher and higher, and the support work of the two safety exits has become a bottleneck restricting the yield benefit and safety benefit. As the support equipment for t...
