Abstract

The utility model discloses a mine single oscillating bar breaking coal hydraulic support, comprising a top beam, a tail beam, a plug board, a plug board jack, a tail beam jack, an oscillating bar, a pull-back slipping jack, a thrusting mechanism, a base and a vertical column; the support is characterized in that: the tail beam is articulated with the upper-rear end of the top beam, the base is articulated with the rear-lower end of the top beam by the oscillating bar, the two ends of the tail beam are respectively articulated with the rear end of the base and the middle-lower end of the tail beam, the plug board is arranged in a guide groove of the tail beam, and the thrusting mechanism is arranged in the base; the hydraulic support cam solve the problems that in the prior art, the lower level of the single oscillating bar is low, the coal placing effect of a plug board bracket is poor and the stability is not good.

Description

A kind of mining single wobbling pole caving roof coal hydraulic support

Technical field

The utility model relates to the hydraulic support technology, particularly a kind of mining single wobbling pole caving roof coal hydraulic support.

Background technology

Fig. 1 is the structural representation of a kind of single wobbling pole caving roof coal hydraulic support of prior art, this hydraulic support by back timber 1, tail boom 2, plate 3, plate jack 4, tail boom jack 5, fork 6, draw the back to slip jack 7, thrust gear 8, base 9, column 10 to form.Wherein fork 6 is hinged with base 9 and back timber 1 lower end respectively, be supported between back timber 1 and the base 9, the tail boom 2 of support is connected the lower end of back timber 1, the two ends of tail boom jack 5 are hinged with the tail bottom and the tail boom 2 of back timber 1 respectively, make tail boom 2 swing controls put coal by tail boom jack 5, thrust gear 8 is installed in the base 9.

Though this of prior art kind of hydraulic support alleviates weight support frame, reduces cost, still there is following defective in it:

(1) the support tail boom is hinged on the back timber bottom, adopts little tail boom to put coal mechanism, and the space is little, and the coal discharge outlet of support is little, and is poor to the destructive characteristics of top coal, poor to the destructiveness of coarse coal, and the support drawing effectiveness is poor, and particularly the hard coal seam exploitation effect is poorer;

(2) little tail boom links to each other with tail boom with back timber by the tail boom jack in the lower hinge of back timber, causes support top-heavy, the power at top in time can not be passed to base plate, and support fork, base are turned round seriously, poor stability.

Summary of the invention

Technical problem to be solved by this invention is, a kind of new type mining single wobbling pole caving roof coal hydraulic support is provided, it adopts the big plate of low level mechanism, the tail boom jack is linked to each other with base, simple in structure, good stability, it is big to put the coal space, can effectively overcome the problem of prior art single wobbling pole low level little plate support drawing effectiveness difference and poor stability.

For achieving the above object, the new type mining single wobbling pole caving roof coal hydraulic support that the utility model provides comprises back timber, tail boom, plate, the plate jack, the tail boom jack, fork, draw back slide jack, thrust gear, base, and column, it is characterized in that, the last rear end of described tail boom and described back timber is hinged, the posterior end of described base and described back timber is hinged by described fork, the two ends of described tail boom jack are hinged with the middle lower end of the rear end of described base and described tail boom respectively, described plate is installed in the guide groove of described tail boom, and described thrust gear is installed in the described base.

Above-mentioned mining single wobbling pole caving roof coal hydraulic support is characterized in that, described back timber, tail boom and base all are the box overall structures that is welded into steel plate.

Above-mentioned mining single wobbling pole caving roof coal hydraulic support is characterized in that, described back timber is the curved back timber of a whole rigidity.

Above-mentioned mining single wobbling pole caving roof coal hydraulic support is characterized in that described thrust gear is a pusher structure.

Compare with existing caving roof coal hydraulic support, hydraulic support of the present utility model has following advantage:

The one, connects the effective of top and control top board with the empty top portion of the back timber immediate support of machine after-poppet, can more effectively manage top board;

The 2nd, adopts the top beam rear end of big tail boom and support hinged, and hunting range is big, and is big to the loose range of top coal, and drawing effectiveness is good;

The 3rd. adopt big tail boom mechanism, tail boom built-in inserted plate stroke is long, and coal discharge outlet is big, destructive strong to coarse coal, drawing effectiveness is good;

The 4th. the tail boom jack links to each other with the rear end of base at tail boom, and setting load is big, and loosening top coal scope is big, and effectively the external force with top board in time passes to base and base plate, and the good stability of support is strong to the compliance of hard coal.

For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperate appended graphicly, be described in detail below.

Description of drawings

Fig. 1 is the structural representation of the single wobbling pole caving roof coal hydraulic support of prior art;

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing, with purpose, scheme and the effect of further understanding the utility model, but not as the restriction to the utility model claim protection domain.

Fig. 2 is the example structure schematic diagram of the mining single wobbling pole caving roof coal hydraulic support of the utility model, with reference to figure 2, this new type mining single wobbling pole caving roof coal hydraulic support comprises back timber 10, tail boom 20, plate 30, plate jack 40, tail boom jack 50, fork 60, draws back slide jack 70, thrust gear 80, base 90, column 100 to form.Wherein back timber 10, tail boom 20, base 90 are the box overall structures that are welded into steel plate.Back timber 10 is the curved back timber of a whole rigidity, and its front end upwarps that to connect the top effective, and the rear end is hinged on tail boom 20 and the back timber 10, and is good to the compliance of hard coal.Base 90 and back timber 10 posterior ends are hinged by fork 60, and the two ends of tail boom jack 50 are hinged with the middle lower end of the rear end of base 90 and tail boom 20 respectively, effectively top pressure passed to base plate, and broken simultaneously coal can be strong, and it is big that support is put the coal space.Plate 30 is installed in the guide groove of tail boom 20, and thrust gear 80 is installed in the middle of the base 90, and wherein thrust gear 80 is a pusher structure.

The operating process of support: 1, coal-winning machine is adopted the heel machine and is moved frame.2, push away preceding slide.3, put coal.4, receive the rear portion conveyer.The back timber front end of support inserts empty top portion, roof supporting when moving frame with machine.When putting coal, can operate the tail boom jack and drive the tail boom swing, also can operate plate jack drive plate and move in the tail boom guide groove, coal is put in control.

Though the utility model discloses as above with a preferred embodiment; right its is not in order to limit the utility model; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
