Abstract
The utility model relates to a support equipment used in underground mining working face, in particular to a mobile scaffold for underground coal mining working face. The utility model is composed of a drag beam, a roof beam, a support column and a hydraulic cylinder; one end of the move-in hydraulic cylinder is connected with the drag beam, while the other end is connected with the roof beam; the end socket of the drag beam is provided with a connecting sleeve connected with other drag beams. When in operation, all the components will be assembled and connected as an integrity which is of strong adaptability, high stability, convenient and fast moving and can be synchronized with a coal mining machine.
Description
Technical field
The utility model relates to a kind of support apparatus that uses at the underground mining work plane, particularly a kind of traversing carriage that is used for stope under the coal mine.
Background technology
At present, the existing support apparatus of home and abroad colliery underground mining work plane can be divided into from move mode: plug-type, crawler type, step type and sliding.All be not suitable for large inclination working surface, soft seat work plane, pressure large working area; When breaking roof work plane and top-coal caving face use, also to lay wire lath thereon in addition, exist the scope of application little, use the high shortcoming of cost.
Technical scheme
The purpose of this utility model provides the sectional shelf-unit that a kind of band that uses drags beam in the big work plane of high inclination-angle, soft seat, pressure, it can be by dragging the integral body that is connected to form between beam, even in breaking roof work plane or top-coal caving face, use, because the gap between support need not re-lay wire lath less than 150 millimeters.
The purpose of this utility model is to realize like this, drag the sectional shelf-unit of beam by the band that drags beam, back timber, pillar, hydraulic cylinder to form, comprise that also two forward and backward beams that drag that are arranged in parallel are connected with the rectangle back timber by the PF cylinder pressure respectively, forward and backward drag the beam-ends headband to have to connect other drag the branch sleeve of beam, four hydraulic props are vertically connected on the lower end of rectangle back timber respectively.
PF cylinder pressure one end is connected with dragging beam, and the other end is connected with the rectangle back timber, on the rectangle back timber beam slab is housed, and has the support hydraulic cylinder in the hydraulic prop.
The utility model has the advantages that: good integrity when being used in combination, compliance is strong, stability is high, and is convenient, fast when needs are mobile, can be synchronous with coal-winning machine.

The specific embodiment
Below in conjunction with the embodiments the utility model is described in further details with reference to the accompanying drawings.
During use, at first band is dragged the sectional shelf-unit of beam to arrange successively, the supporting cylinder in the hydraulic prop 79 to the prolonging direction fluid injection, is made rectangle back timber 5 add suitable power and is supported on the roof at work plane.To before drag beam 1 to couple together one by one with branch sleeve 6 then; Equally with branch sleeve 6 with after drag beam 2 to couple together one by one; Thereby make each band drag the sectional shelf-unit of beam to connect into whole support apparatus on the work plane.Behind the working face mining, when shipper pole dragged the sectional shelf-unit of beam before needing, operating procedure was as follows:
1) to all PF cylinder pressures 3 simultaneously to the prolonging direction fluid injection, drag before making beam 1 below rectangle back timber 5 along the i iron lower edge to step pitch of front slide;
2) to all PF cylinder pressures 4 simultaneously to shortening the direction fluid injection, drag after making beam 2 below rectangle back timber 5 along the i iron lower edge to step pitch of front slide;
3) successively to four supporting cylinders in each sectional shelf-unit 9 simultaneously to shortening the direction fluid injection, hydraulic prop 7 unloadings are mentioned, break away from seat earth, rectangle back timber 5 breaks away from roofs, drops on its forward and backward dragging on the beam 1,2;
4) successively rectangle back timber 5 has been dropped on its forward and backward sectional shelf-unit that drags on the beam 1,2, shorten direction fluid injection, the 4 prolonging direction fluid injections of PF cylinder pressure for simultaneously its PF cylinder pressure 3, make its rectangle back timber 5 under the active force of two PF cylinder pressures, drag the step pitch of reach of sliding on the beam at it;
5) to four supporting cylinders in the sectional shelf-unit that has moved forward 9 simultaneously to the prolonging direction fluid injection, make its rectangle back timber 5 add suitable power by hydraulic prop 7 and be supported on the roof.
Claims (5)
1, a kind of band drags the sectional shelf-unit of beam, form by dragging beam, back timber, pillar, hydraulic cylinder, it is characterized in that two be arranged in parallel before drag beam 1, after drag beam 2 to be connected with rectangle back timber 5 by PF cylinder pressure 3,4 respectively, before drag beam 1, after drag beam 2 terminations to have to connect other and drag 6, four hydraulic props 7 of branch sleeve of beam to be vertically connected on the lower end of rectangle back timber 5 respectively.
2, drag the sectional shelf-unit of beam according to the said band of claim 1, it is characterized in that PF cylinder pressure 3 one ends are connected with before dragging beam 1, the other end is connected with rectangle back timber 5.
3, drag the sectional shelf-unit of beam according to the said band of claim 1, it is characterized in that PF cylinder pressure 4 one ends with after drag beam 2 to be connected, the other end is connected with rectangle back timber 5.
4, drag the sectional shelf-unit of beam according to the said band of claim 1, it is characterized in that being equipped with on the rectangle back timber 5 beam slab 8.
5, drag the sectional shelf-unit of beam according to the said band of claim 1, it is characterized in that having in the hydraulic prop 7 support hydraulic cylinder 9.
