Abstract
The utility model discloses a thin-coal-seam hydraulic bracket bottom-lifting device. The thin-coal-seam hydraulic bracket bottom-lifting device is characterized by comprising a bent bottom-lifting rocking arm and an inclined bottom-lifting jack, wherein one end of the bottom-lifting rocking arm and one end of the bottom-lifting jack are respectively hinged with a base of a hydraulic bracket; the other end of the bottom-lifting jack is hinged with the bottom-lifting rocking arm; the other end of the bottom-lifting rocking arm is a lifting end; and the lifting of bottom-lifting jack drives the bottom-lifting rocking arm to rotate. The bottom-lifting jack is inclined, simple in structure, convenient to mount and maintain, and large in bottom-lifting distance.
Description
Technical field
The utility model relates to a kind of technical field of support apparatus in coal mine, and specifically a kind of coal mine fully-mechanized mining working is used for the hydraulic support for low coal seam bottom lifting device.
Background technology
The hydraulic support for low coal seam bottom lifting device is the important mechanism of fully-mechanized mining working surface hydraulic support of the soft end.The major function of hydraulic support for low coal seam bottom lifting device is a support when pricking the end, lifts bracket base, is convenient to support and passes.
At present, following problem has in use appearred in the bottom lifting device of the type:
(1) existing bottom lifting device is vertical the layout, and it is big to take up room, and causes the Bracket in Thin Coal Seam bottom lifting device to install;
(2) vertically arranged bottom lifting device complex structure is lifted problems such as little, the difficult maintenance of end distance.
Summary of the invention
To above deficiency, the purpose of the utility model is to provide a kind of hydraulic support for low coal seam bottom lifting device, the utility model lift that end jack is in tilted layout and simple in structure, be easy for installation and maintenance, it is big to lift end distance.
For achieving the above object, the technical scheme of the utility model is:
A kind of hydraulic support for low coal seam bottom lifting device comprises and lifts end rocking arm, lifts end jack; The described end rocking arm of lifting is hinged on respectively on the base of hydraulic support with an end of lifting end jack, lifts the hinged end rocking arm of lifting of the other end of end jack, and the other end of lifting end rocking arm is for lifting end; Lift jack action drive and lift end rocking arm rotation.
Further, the described jack that lifts is obliquely installed.
Further, the described end rocking arm of lifting is a curved shape.
Further, the described upper articulation of lifting end rocking arm is on base, and the middle part is with to lift end jack hinged.
Further, the said jack that lifts is hinged on the maximum curvature place that end rocking arm is lifted in bending.
Further, the described jack that lifts is positioned at the side to outer lug that end rocking arm is lifted in bending.
Further, the described rocking arm that lifts lifts end and turns to when bottom, and it is corresponding with the pusher rod of hydraulic prop to lift end.
The operating principle of the utility model promptly reaches beneficial effect:
The utility model is hinged with the cylinder bottom end of lifting end jack at base, lifts end jack piston rod end and lift end rocking arm hinged.Through lifting stretching out or shrink to make and lifting end rocking arm of end jack, and make and lift end rocking arm and be pressed on the pusher rod, lift the purpose at the end to reach base along base and the jointed shaft rotation of lifting end rocking arm.
Compared with prior art, lift jack and be obliquely installed, and lift swing arm and adopt the bending design, not only solved the problem that the Bracket in Thin Coal Seam bottom lifting device can't be installed, especially simple in structure, lift end distance big, be easy for installation and maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1 is that pusher rod, 2 is that base, 3 is for lifting end rocking arm, 4 for lifting end jack.
The specific embodiment
Be described further according to accompanying drawing, as scheme to combine accompanying drawing that the utility model is further described at present, Fig. 1 is a kind of enforcement of the utility model.
As shown in Figure 1, a kind of hydraulic support for low coal seam bottom lifting device comprises and lifts end rocking arm 3, lifts end jack 4.
The described end rocking arm 3 of lifting is curved shape, and its upper end is hinged on the base 2 through gudgeon, the hinged tailpiece of the piston rod of lifting end jack 4 in middle part maximum curvature place, and the other end of lifting end rocking arm 3 is for lifting end.
The other end of lifting end jack 4 just oil cylinder end is hinged on the base 2 of hydraulic support through gudgeon, lifts end jack 4 and satisfies and are obliquely installed; And lift jack 4 and be positioned at the crooked side to outer lug of lifting end rocking arm 3.
Lift rocking arm 3 and lift end and turn to when bottom, it is corresponding with the pusher rod 1 of hydraulic prop to lift end.
During use; Since the utility model lift end rocking arm 3 under the effect of lifting end jack 4; Rotating the end of lifting of realizing support around jointed shaft moves; Not only solved Bracket in Thin Coal Seam the difficult problem of bottom lifting device can't be installed, and had simple in structurely, be easy for installation and maintenance and lift the big characteristics of end distance.
