Abstract
The invention discloses a great-drop transition support. One side of a top beam is hinged with a side baffle plate, and an obliquely pushing jack is connected between the side baffle plate and the top beam. When the great-drop transition support is applied to a coal bed with a greater working face drop, one side with the side baffle plate can be arranged toward a shorter end support, and the other side is arranged toward a higher working face support. Therefore, the problems on great coal bed drop and exploitation support can be solved, meanwhile, the problem on recovery rate of lots of coal beds can also be solved.
Description
Technical field
The present invention relates to the suspension device that uses under a kind of coal mine, relate in particular to a kind of big drop transition bracket.
Background technology
Along with the quick growth of coal demand, various colliery both domestic and external emerges like the mushrooms after rain, and the geological conditions in each colliery has nothing in common with each other, and the coal seam excursion is big.The work plane mining height is bigger, and the end support height is less.
As shown in Figure 1, in the prior art, the support in the work plane in big drop coal seam adopts by face end support 01, many transition brackets 02 usually gradually to the arrangement of intermediate support 03 transition.
There is following shortcoming at least in above-mentioned prior art:
Though this kind arrangement is also to have solved the big problem of coal seam drop substantially, can cause the coal of Delta Region, support top to be wasted.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can solve the big problem of coal seam drop, also can stop the big drop transition bracket that a large amount of coals are wasted in the big drop coal seam simultaneously.
The objective of the invention is to be achieved through the following technical solutions:
Big drop transition bracket of the present invention comprises back timber, column, and a side of described back timber is hinged with side shield, is connected with the cant jack between described side shield and the described back timber.
As seen from the above technical solution provided by the invention, the big drop transition bracket that the embodiment of the invention provides because a side of back timber is hinged with side shield, is connected with the cant jack between side shield and the back timber.When being applied to the bigger coal seam of drop, can will be provided with a side of side shield towards shorter face end support, opposite side can solve the big problem of coal seam drop towards higher intermediate support, also can stop the problem that a large amount of coals are wasted in the big drop coal seam simultaneously.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is the layout design sketch of transition bracket in the big drop working face of coal seam in the prior art;
The structural representation of the big drop transition bracket that Fig. 2 provides for the embodiment of the invention;
Fig. 3 be in the embodiment of the invention big drop transition bracket at the layout design sketch of work plane.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on embodiments of the invention, those of ordinary skills belong to protection scope of the present invention not making the every other embodiment that is obtained under the creative work prerequisite.
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Big drop transition bracket of the present invention, its preferable specific embodiment be as shown in Figure 2:
Comprise back timber 4, column 5, a side of described back timber 4 is hinged with side shield 6, is connected with cant jack 7 between described side shield 6 and the described back timber 4.
The height of described side shield 6 can be more than or equal to 2 meters.
The height of described side shield 6 can be more than or equal to 1/2 of the supporting height of this support.
As shown in Figure 3, when big drop transition bracket 2 of the present invention is applied to the bigger coal seam of drop, can will be provided with a side of side shield towards shorter face end support 1, opposite side is towards higher intermediate support 3, can solve the big problem of coal seam drop, also can stop the problem that a large amount of coals are wasted in the big drop coal seam simultaneously.
" big drop " among the present invention refers to the coal seam that drop is bigger, is the call of this area custom, and concrete value not refers generally to drop more than or equal to one and half or two meters coal seam.
The present invention is in conjunction with the geological conditions in big drop coal seam, adopt a kind of big drop transition bracket, can solve the big problem of coal seam drop, also can stop simultaneously the situation that a large amount of coals are wasted in the big drop coal seam, the coal of Delta Region is fully reclaimed, and the coal supply mine belt comes huge economic benefit.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
