Abstract
The utility model discloses a bracket device, comprising a left supporting plate, a left top plate, a right top plate, a right supporting plate, a left hydraulic cylinder, an upper hydraulic cylinder and a right hydraulic cylinder, wherein the left supporting plate is hinged with the left top plate; the left top plate is hinged with the right top plate; the right top plate is hinged with the right supporting plate; the left supporting plate is hinged with one end of the left hydraulic cylinder; the other end of the left hydraulic cylinder is hinged with the left top plate; one end of the upper hydraulic cylinder is hinged with the left top plate and the other end of the upper hydraulic cylinder is hinged with the right top plate; one end of the right hydraulic cylinder is hinged with the right top plate and the other end of the right hydraulic cylinder is hinged with the right supporting plate. According to the utility model, a flexible supporting device is provided on the basis that situations that a supporting force is stable, operation is simple and convenient and a supported drive is unlikely to generate roof leakage and easy to carry are guaranteed, and safe and reliable support is provided for coal mining under the condition of steep seam or operation under the similar steep condition.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of for the holder device under the high-dipping operating condition.
Technical background
The support apparatus in colliery is the important leverage of coal miner safety coal mining, especially under the half-edge coal seam condition, larger from the pressure of top board (coal seam), because the not good security incident caused of supporting performance happens occasionally.
At present, in the exploitation of half-edge coal seam, generally use " flexible support coal-mining method ".This supporting structure form is that i iron is processed into to polygon, then with wire rope, h beam cap is linked together, and forms the disjunctor supporting of whole work plane.This support can provide supporting for exploitation at the half-edge coal seam pseudo-oblique arrangement of taking to bow substantially, and has economic benefit and social benefit preferably.
Although this supporting has solved the supporting problem of work plane to a certain extent, make work plane that safer production environment arranged, this supporting also has its obvious shortcoming.One, because the support arm of this kind supporting is thinner, make between support easily to leak to push up and hurt sb.'s feelings; Its two, because the operating angle of the support of this kind supporting is non-adjustable, so it is to the bad adaptability in top board coal seam; Its three, it does not have hydraulic operation and control system and can't fold, and needs frequent dismounting and is difficult for carrying, causes workman's labour intensity large; In addition, the easy Folding Deformation of wire rope so that disrumpent feelings.
Therefore, develop a kind of strong adaptability, supporting intensity large, simple to operate, be difficult for causing Lou top and be easy to remove the imperative for half-edge coal seam flexible support device of carrying, this is also in mine safety production, to be badly in need of the problem solved.
The utility model content
The purpose of this utility model is to guarantee that support force is stable, easy and simple to handle, supported drive is difficult for occurring leak top and be easy to remove on the basis of carrying, provide a kind of for the holder device under the high-dipping operating condition, the support shield of safety and reliability is provided for the coal mining under the half-edge coal seam condition.
To achieve these goals, the utility model has been taked following technical scheme.
A kind of holder device, comprise left support plate, left roof, right top board, right support plate, left hydraulic cylinder, upper hydraulic cylinder, right hydraulic cylinder.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 an end and the left roof of upper hydraulic cylinder are hinged, and the other end of upper hydraulic cylinder and right top board are hinged, one end and the right top board of right hydraulic cylinder are hinged, and the other end of right hydraulic cylinder and right support plate are hinged.
Further, between described left support plate, left roof, right top board and right support plate, by being hinged and connected, and can to operating angle, regulate and control by hydraulic system.
Further, the plate of described left support plate, left roof, right top board and right support plate is wide all over rice.
Further, an end of described 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, holder device provided by the utility model has following effect:
1) between the left support plate of this device, left roof, right top board and right support plate by being hinged and connected, and can to operating angle, regulate by hydraulic system, and the adjustability of operating angle is larger, thereby make this suspension device have compliance preferably for the top board coal seam;
2) this device metal sheet of using width to surpass 1 meter Metallic rod structure be processed into by i iron of having replaced being widely used, so it is larger with the coal seam contact surface, makes between supporting to be difficult for producing leakage top phenomenon;
3) this device can carry out folding shrinking by hydraulic cylinder, when removing equipment, can pass through to control the quick reclaimer of hydraulic system, thereby more save manpower and time than conventional art.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is effect structure figure of the present utility model;
Fig. 3 is folding shrinking schematic diagram of the present utility model.
In figure, 1--left support plate, 2--left roof, the right top board of 3--, 4--right support plate, 5--left hydraulic cylinder, the upper hydraulic cylinder of 6--, the right hydraulic cylinder of 7--.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model 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 an end of left hydraulic cylinder 6, the other end of left hydraulic cylinder 6 and left roof 2 are hinged, and an end and the left roof 2 of upper hydraulic cylinder 6 are hinged, and the other end of upper hydraulic cylinder 6 and right top board 3 are hinged, one end and the right top board 3 of right hydraulic cylinder 7 are hinged, and the other end of right hydraulic cylinder 7 and right support plate 4 are hinged.
As shown in Figure 3, when device shrank, left hydraulic cylinder 5 and right hydraulic cylinder 7 were overhanging, upper hydraulic cylinder 6 retractions, thus make device complete contraction.
The utility model is guaranteeing that support force is stable, easy and simple to handle, supported drive is difficult for occurring leak top and be easy to remove on the basis of carrying, provides a kind of holder device, for operation under the similar high-dipping condition of half-edge coal seam conditioned disjunction provides the support shield of safety and reliability.
Above a kind of holder device provided by the utility model is described in detail, for one of ordinary skill in the art, thought according to the embodiment of the present invention, all will change in specific embodiments and applications, can do respective change according to actual needs.In sum, this description should not be construed as restriction of the present utility model.
