Description
Technical field
The utility model relates to a kind of bottom lifting mechanism of hydraulic support, belongs to mine support technical field of mechanical equipment.
Background technology
The hydraulic support that coal pit mining coal uses, pedestrian's limited space; Particularly thin seam mining, mining height is low, down-hole pedestrian's limited space, requires the compact overall structure of Design of Powered Supports.
Traditional bottom raising mechanism is arranged, not only need to take limited pedestrian space, and the mining height scope adapted to is restricted, bringing difficulty to the compliance of hydraulic support and downhole production efficiency, is the needs that conserve space or hydraulic support mining height scope all can not meet existing particularly thin seam mining.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of compact conformation rationally, conserve space, easy to operate and ensure that the bottom lifting mechanism of hydraulic support of the safety production environment of down-hole.
Bottom lifting mechanism of hydraulic support described in the utility model, comprise and lift end jack, pusher rod, first support arm, second support arm and the 3rd support arm, lift end jack and each support arm is all placed horizontally in hydraulic support foundation front portion, lift the otic placode that the cylinder body tail end of end jack and hydraulic support foundation front end arrange hinged, piston rod top and the first support arm, second support arm is coaxially hinged, first support arm, second support arm is symmetricly set on piston rod both sides, 3rd support arm between the first support arm and the second support arm and with the first support arm, second support arm is arranged in opposite directions, each support arm structure is identical, otic placode on outer end and each self-corresponding hydraulic support foundation is hinged, the inner has gathering sill, inner bottom has outstanding support end, pusher rod is positioned at below support end, three support arms are coaxially hinged with the gathering sill respectively had.
Operating principle and process:
During work, lift end jack and stretch, drive each support arm along gathering sill moved in coaxial, each support arm is drawn close, when the support end of support arm drops in pusher rod, with this contact point for fulcrum to inner (i.e. the centre position of three support arms), lever force is utilized to make hydraulic support foundation leave ground, the end, is lifted in realization, afterwards, lifts end jack and regains, support arm support end is driven to rise, leave pusher rod, hydraulic support foundation falls back ground, completes and lifts end action.
In mechanism, owing to lifting end jack and each support arm is all placed horizontally in hydraulic support foundation front portion, compact conformation, the anterior pedestrian space of hydraulic support can be saved, downhole safety production environment is guaranteed, and integrated hydraulic support to lift the end simple and efficient to handle, be convenient to implement.
The beneficial effect that the utility model is compared with prior art had is:
This bottom lifting mechanism of hydraulic support structure design compact and reasonable, utilization is lifted end jack and is stretched support arm, three support arms can be made along gathering sill moved in coaxial, each support end to drop in pusher rod and as fulcrum, lever force is utilized to make hydraulic support foundation leave ground, complete and lift end action, whole simple and efficient to handle, be convenient to implement, and lift end jack and each support arm is all placed horizontally in base front portion, therefore, it is possible to save the anterior pedestrian space of hydraulic support, downhole safety production environment is guaranteed.

Fig. 3 is the top view of Fig. 1.
In figure: 1, pusher rod; 2, hydraulic support foundation; 3, otic placode; 4, cylinder body; 5, piston rod; 6, the first support arm; 7, gathering sill; 8, support end; 9, the 3rd support arm; 10, otic placode; 11, the second support arm.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 3, this bottom lifting mechanism of hydraulic support comprises lifts end jack, pusher rod 1, first support arm 6, second support arm 11 and the 3rd support arm 9, lifting end jack and each support arm, to be all placed horizontally in hydraulic support foundation 2 anterior, lift the otic placode 3 that cylinder body 4 tail end of end jack and hydraulic support foundation 2 front end arrange hinged, piston rod 5 top and the first support arm 6, second support arm 11 is coaxially hinged, first support arm 6, second support arm 11 is symmetricly set on piston rod 5 both sides, 3rd support arm 9 between the first support arm 6 and the second support arm 11 and with the first support arm 6, second support arm 11 is arranged in opposite directions, each support arm structure is identical, otic placode 10 on outer end and each self-corresponding hydraulic support foundation 2 is hinged, the inner has gathering sill 7, inner bottom has outstanding support end 8, pusher rod 1 is positioned at below support end 8, three support arms are coaxially hinged with the gathering sill 7 respectively had.
Operating principle and process:
During work, lift end jack and stretch, drive each support arm along gathering sill 7 moved in coaxial, each support arm is drawn close, when the support end 8 of support arm drops in pusher rod 1, with this contact point for fulcrum to inner (i.e. the centre position of three support arms), lever force is utilized to make hydraulic support foundation 2 leave ground, the end, is lifted in realization, afterwards, lifts end jack and regains, support arm support end 8 is driven to rise, leave pusher rod 1, hydraulic support foundation 2 falls back ground, completes and lifts end action.
In mechanism, owing to lifting end jack and each support arm, to be all placed horizontally in hydraulic support foundation 2 anterior, compact conformation, the anterior pedestrian space of hydraulic support can be saved, downhole safety production environment is guaranteed, and integrated hydraulic support to lift the end simple and efficient to handle, be convenient to implement.
