Abstract
The utility model relates to a support device used on the working surface of underground mining, in particular to a movable support used on the working surface in underground coal extraction, which comprises a plurality of joists, propping girders, member bars, support pillars and a hydraulic cylinder; wherein, the end of the connecting member bar perpendicular to the joistis connected with the front joist, the other end is connected with the rear joist for pushing one end of the hydraulic cylinder to be connected with the propping girders, and the other end is connected with a joist; a connecting sleeve is arranged on the end head of each joist for connecting other joists. While in use, the components are connected into a whole; therefore, the utility model has the advantages of strong adaptability, high stability, and more convenient and rapid movement.
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, in the prior art, with the forward and backward sectional shelf-unit that drags beam, its forward and backward dragging there is no connection between the beam, but reaches forward and backward purpose of dragging beam to move respectively by PF cylinder pressure separately.Its defective is the molar behavior complexity, and required time is long, use two PF cylinder pressures, just can finish its whole reach.
Technical scheme
The purpose of this utility model provides a kind of synchronization-moving sectional shelf-unit of beam that drags, the forward and backward beam that drags can be moved under the effect of a PF cylinder pressure together, both reduced required step and the time in the support reach, again two PF cylinder pressures in the support are kept to one, have reduced the manufacturing cost of support.
The purpose of this utility model is achieved in that by what drag that beam, back timber, rod member, pillar, hydraulic cylinder form drags the synchronization-moving sectional shelf-unit of beam, comprises that also the connecting rod vertical with dragging beam one end is connected with before dragging beam, the other end with after drag beam to be connected; PF cylinder pressure one end is connected with the rectangle back timber, and the other end is connected with dragging beam; Forward and backward drag the beam-ends headband to have to connect other drag the branch sleeve of beam, hydraulic prop is vertically connected on the lower end of rectangle back timber respectively; Connecting rod can be one, also can be two; PF cylinder pressure one end is connected with the rectangle back timber, the other end with after drag beam to be connected; The PF cylinder pressure can also be connected with the rectangle back timber by an end, and the other end is connected with before dragging beam; On the rectangle back timber beam slab is housed, has supporting 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 when needs are mobile, convenient, quick.

The specific embodiment
Below in conjunction with the embodiments the utility model is described in further details with reference to the accompanying drawings.
Embodiment 1
It is that front end with PF cylinder pressure 4 fixes on the beam slab 8 by hinges fixing, drags on the beam 1 before its rear end fixes on by hinges fixing, and all the other structures are identical with embodiment 1.
It is with the two ends of a rigidity connecting rod 3 respectively with preceding drag beam 1, after drag beam 2 vertical hinged, drag before making beam 1 with after drag 2 one-tenth on beam as a whole, all the other structures are with embodiment 1.
During use, at first will drag the synchronization-moving 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 drag the synchronization-moving sectional shelf-unit of beam to connect into whole support apparatus on the work plane.Behind the working face mining, when needing reach to drag the synchronization-moving sectional shelf-unit of beam, operating procedure is as follows:
1) to all PF cylinder pressures 4 simultaneously to shortening the direction fluid injection, make the forward and backward beam 1,2 that drags at square
Shape back timber 5 belows along the channel-section steel lower edge to step pitch of front slide;
2) successively to four supporting cylinders in each sectional shelf-unit 9 simultaneously to shortening the direction fluid injection, make liquid
Press pillar 7 unloadings to mention, break away from seat earth, rectangle back timber 5 disengaging roofs, drop on it
Forward and backward dragging on the beam 1,2;
3) successively rectangle back timber 5 has been dropped on its forward and backward sectional shelf-unit that drags on the beam 1,2, to its propelling
Drag the step pitch of reach of sliding on the beam at it;
4) to four supporting cylinders in the sectional shelf-unit that has moved forward 9 simultaneously to the prolonging direction fluid injection, by
Hydraulic prop 7 makes its rectangle back timber 5 add suitable power and is supported on the roof.
