Abstract
The utility model discloses a temporary supporting frame. The temporary supporting frame comprises a left supporting plate, a right supporting plate and a plurality of top plates; the temporary supporting frame is characterized by further comprising a left hydraulic cylinder, a right hydraulic cylinder and a plurality of upper hydraulic cylinders, wherein the two ends of each upper hydraulic cylinder are respectively connected with two top plates; one end of the left hydraulic cylinder is hinged with the left supporting plate; the other end of the left hydraulic cylinder is hinged with the top plate connected with the left supporting plate; one end of the right hydraulic cylinder is hinged with the right supporting plate; the other end of the right hydraulic cylinder is hinged with the top plate connected with the right supporting plate. On the basis of ensuring the supporting force is stable, the operation is easy and convenient, and a supported mine path is hard to have top leakage and can enable the transportation to be easy, the utility model provides the temporary supporting frame which provides safe and reliable supporting cover for coal mining under a high-dipping coal-bed condition.
Description
Technical field
The utility model belongs to the coal mine support field of mechanical technique, particularly a kind of device of flexible support for half-edge coal seam.
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 top Lou and be easy to remove the temporary lining frame of carrying imperative, 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, and a kind of temporary lining frame is provided, and 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 temporary lining frame, comprise left support plate, right support plate, and some top boards, it is characterized in that, also comprise left hydraulic cylinder, right hydraulic cylinder, and some upper hydraulic cylinders, the two ends of described upper hydraulic cylinder connect respectively two top boards, one end and the left support plate of described left hydraulic cylinder are hinged, and the other end is hinged with the top board that is connected the left support plate; One end and the right support plate of right hydraulic cylinder are hinged, and the other end is hinged with the top board that is connected the right support plate.
Further, described upper hydraulic cylinder is asymmetric is hinged on two top boards.
Further, between described left support plate, each top board and right support plate, by being hinged and connected, and can to operating angle, regulate and control by hydraulic system.
As preferably, the plate of described left support plate, left roof, right top board and right support plate is wide all over 1 meter.
Compared with prior art, flexible support 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 thick plate 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, a kind of temporary lining frame, comprise left support plate 1, left roof 2, right top board 3, right support plate 4, also comprises left hydraulic cylinder 5, upper hydraulic cylinder 6, right hydraulic cylinder 7; One end and the left roof 2 of described upper hydraulic cylinder 6 are hinged, and the other end and right top board 3 are hinged, and upper hydraulic cylinder 6 is asymmetric to be hinged on left roof 2 and right top board 3.
One end and the left support plate 1 of described left hydraulic cylinder 6 are hinged, and the other end and left roof 2 are hinged; One end and the right top board 3 of right hydraulic cylinder 7 are hinged, and the other end and right support plate 4 are hinged.
Described left support plate 1 is hinged with an end of left hydraulic cylinder 6, by being hinged and connected, and can to operating angle, regulate and control by hydraulic system between described left support plate 1, left roof 2, right top board 3 and right support plate 4.
As figure, an end of the upper hydraulic cylinder 6 in the present embodiment 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 right top board 3 is near the base of right top board 3.
Also can be set to the base of the pin joint of an end of hydraulic cylinder 6 and left roof 2 near left roof 2, the top margin of the close right top board 3 of the pin joint of the other end and right top board 3.
The plate of described left support plate 1, left roof 2, right top board 3 and right support plate 4 is wide all over 1 meter.
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, and supported drive is difficult for occurring leak top and be easy to remove on the basis of carrying, and a kind of temporary lining frame is provided, and the support shield of safety and reliability is provided for the coal mining under the half-edge coal seam condition.
Above a kind of temporary lining frame provided by the utility model is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
