Abstract
The utility model discloses a big-drop transition bracket, wherein a side baffle plate is hinged on one side of a top beam, and an inclined pushing jack is connected between the side baffle plate and the top beam. When the big-drop transition bracket is applied to the coal seam with bigger working face drop, the side of the bracket mounted with the side baffle plate faces to an end bracket with a lower height, and the other side thereof faces to a working face bracket with a higher height, therefore not only the problems of coal seam big drop and mining support are solved, but also the problem of the recovery rate of a large amount of coal seams is solved.
Description
Technical field
The utility model relates to the suspension device that uses under a kind of coal mine, relates 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.
The utility model content
The purpose of this utility model provides 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 purpose of this utility model is achieved through the following technical solutions:
Big drop transition bracket of the present utility model 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.
The technical scheme that provides by above-mentioned the utility model as can be seen, the big drop transition bracket that the utility model embodiment 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 utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, 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 utility model embodiment;
Fig. 3 be among the utility model embodiment big drop transition bracket at the layout design sketch of work plane.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that is obtained under the creative work prerequisite.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Big drop transition bracket of the present utility model, 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 utility model 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 " in the utility model 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 utility model 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; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
