Description
Technical field
The invention belongs to coal mine support field of mechanical technique, particularly a kind of flexible support device for half-edge coal seam.
Technical background
The support apparatus in colliery is the important leverage of coal miner safety coal mining, and especially under half-edge coal seam condition, the pressure from top board (coal seam) is comparatively large, and the security incident caused because supporting performance is not good happens occasionally.
At present, in the exploitation of half-edge coal seam, generally " flexible support coal-mining method " is used.This support configurations is that i iron is processed into polygon, is then linked together by h beam cap with wire rope, forms the disjunctor supporting of whole work plane.This support can provide supporting at half-edge coal seam pseudo-oblique arrangement of taking to bow for exploitation substantially, and has good economic benefit and social benefit.
Although this supporting to some extent solves the support issues of work plane, work plane is had safer production environment, this supporting also has its obvious shortcoming.One, because the support arm of this kind of supporting is comparatively thin, makes easily to leak top between support and hurts sb.'s feelings; Its two, because the operating angle of the support of this kind of supporting is non-adjustable, therefore it is to the bad adaptability in top board coal seam; Its three, it does not have hydraulic operation and control system and cannot fold, and needs frequent dismounting and not easily carries, causing the labour intensity of workman large; In addition, the easy Folding Deformation of wire rope is consequently disrumpent feelings.
Therefore, develop a kind of strong adaptability, supporting intensity large, simple to operate, not easily cause Lou top and be easy to remove the imperative for half-edge coal seam flexible support device of carrying, this is also the problem being badly in need of in mine safety production solving.
Summary of the invention
The object of the invention is to stablize at guarantee support force, easy and simple to handle, not easily occurred leak top and be easy to remove on the basis of carrying by support drive, provide a kind of for half-edge coal seam flexible support device, for the coal mining under half-edge coal seam condition provides the support shield of safety and reliability.
To achieve these goals, this invention takes following technical scheme.
For a flexible support device for half-edge coal seam, comprise left support plate, left roof, right top board, right support plate, left hydraulic cylinder, upper hydraulic cylinder, right hydraulic cylinder.Left support plate and left roof hinged, left roof and right top board hinged, right top board and right support plate hinged, one end of left support plate and left hydraulic cylinder is hinged, the other end and the left roof of left hydraulic cylinder are hinged, and one end and the left roof of upper hydraulic cylinder are hinged, and the other end and the right top board of upper hydraulic cylinder are hinged, one end and the right top board 3 of right hydraulic cylinder are hinged, and the other end and the right support plate of right hydraulic cylinder are hinged.
Further, described left support plate, left roof, between right top board and right support plate by being hinged and connected, and by hydraulic system, operating angle to be regulated and controled.
Further, the plate of described left support plate, left roof, right top board and right support plate is wide all more than 1 meter.
Further, described one end of upper hydraulic cylinder and the pin joint of left roof are near the top margin of left roof, and the pin joint of the other end and right top board is near the base of right top board.
Compared with prior art, flexible support device provided by the present invention has following effect:
1) the left support plate of this device, left roof, between right top board and right support plate by being hinged and connected, and by hydraulic system, operating angle is regulated, and the adjustability of operating angle is comparatively large, thus this suspension device is made to have good compliance for top board coal seam;
2) this device uses the metal sheet of width more than 1 meter to instead of the Metallic rod structure be processed into by i iron be widely used, and therefore itself and coal seam contact surface are larger, makes not easily to produce between supporting to leak top phenomenon;
3) this device carries out folding shrinking by hydraulic cylinder, when removing equipment, by the quick reclaimer of hydraulic control system, thus more saves manpower and time than conventional art.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, technical scheme of the present invention is further described.
As depicted in figs. 1 and 2, this example comprises left support plate 1, left roof 2, right top board 3, right support plate 4, left hydraulic cylinder 5, upper hydraulic cylinder 6, right hydraulic cylinder 7.Left support plate 1 is hinged with left roof 2, left roof 2 is hinged with right top board 3, right top board 3 is hinged with right support plate 4, left support plate 1 is hinged with one end of left hydraulic cylinder 6, the other end and the left roof 2 of left hydraulic cylinder 6 are hinged, and one end and the left roof 2 of upper hydraulic cylinder 6 are hinged, and the other end and the right top board 3 of upper hydraulic cylinder 6 are hinged, one end and the right top board 3 of right hydraulic cylinder 7 are hinged, and the other end and the right support plate 4 of right hydraulic cylinder 7 are hinged.
Described left support plate 1, left roof 2, between right top board 3 and right support plate 4 by being hinged and connected, and by hydraulic system, operating angle to be regulated and controled.
The plate of described left support plate 1, left roof 2, right top board 3 and right support plate 4 is wide all more than 1 meter.
One end of described upper hydraulic cylinder 6 and the pin joint of left roof 2 are near the top margin of left roof 2, and the pin joint of the other end and left roof 2 is near the base of right top board.
