Abstract
The utility model discloses a steep coal seam end hydraulic support, which comprises a support base, a telescopic column which is on one end of the support base, a telescopic top beam which is connected with the telescopic column, a support upright post which is arranged between the support base and the telescopic top beam, an advancing jack and a scraper transfer machine tail which are arranged on the support base, wherein the support upright post is arranged on the back of the scraper transfer machine tail, a gangue baffle plate is also arranged in front of the support upright post, and the bottom of the gangue baffle plate is arranged between the scraper transfer machine tail and the support upright post and is connected with the support base. Since the hydraulic support of the utility model adopts a structure that the column is arranged backwards and the scraper transfer machine tail is arranged forwards, thereby the purposes for protecting the column and enlarging passenger space are achieved, and since the support stand is arranged backwards, the under frame sinking phenomenon of an end support is reduced, which enables the end hydraulic support to easily achieve the purpose for advancing with a working face support together.
Description
Technical field
The utility model relates to the hydraulic support in a kind of support apparatus in coal mine field, relates in particular to a kind of half-edge coal seam end hydraulic support.
Background technology
At present, end hydraulic support of the prior art is two sectional shelf-units, be positioned at the work plane lower end, it is the interconnecting device of work plane flexible flightconveyor and machine lane scraper plate elevating conveyor, scraper plate elevating conveyor tail is installed on the face end support, and the pedestrian enters the support work plane by the face end support tailstock.
End hydraulic support of the prior art mainly is applicable to inclination angle large-inclination-angle coal bed less than 45 °, being two is used in combination, column is preceding, scraper plate elevating conveyor tail is positioned at the bracket upright post rear side, when inclination angle the time greater than 45 °, the coal of work plane can quicken automatically, coal and spoil impact bracket upright post, make that like this column is fragile, so existing end hydraulic support can't adapt to the impact of the acceleration coal breakage of present half-edge coal seam, and under the preposition situation of column, also be easy to occur support and prick end phenomenon, and scraper plate elevating conveyor tail postposition, can make that also the pedestrian space is very narrow and small, because retaining cash facility is not set, make the pedestrains safety coefficient greatly reduce again.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, provide a kind of column postposition, the preposition work plane coal breakage that prevents of scraper plate elevating conveyor tail to damage column, prevent column in the base front end bundle end, and can ensure the half-edge coal seam end hydraulic support of walkway safety.
The technical solution of the utility model is achieved in that a kind of half-edge coal seam end hydraulic support, comprise the telescopic mast on bracket base, bracket base one end, the flexible back timber that is connected with telescopic mast, the bracket upright post that is provided with between bracket base and the flexible back timber, place passing jack and scraper plate elevating conveyor tail on the bracket base, described bracket upright post places the back of scraper plate elevating conveyor tail.Be provided with the spoil baffle plate in the front of bracket upright post, the bottom of spoil baffle plate places between scraper plate elevating conveyor tail and the bracket upright post and is connected with bracket base.
The beneficial effects of the utility model are: because the utility model has adopted the column postposition; scraper plate elevating conveyor tail is preposition; thereby reached the protection column and increased the purpose in pedestrian space; and, make end hydraulic support be easy to reach and the common purpose that advances of force piece because the bracket upright post postposition has also reduced its bundle end phenomenon.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, as shown in Figure 1 and Figure 2: a kind of half-edge coal seam end hydraulic support, comprise the telescopic mast 2 on bracket base 1, bracket base 1 one ends, the flexible back timber 3 that is connected with telescopic mast 2, the bracket upright post 4 that is provided with between bracket base 1 and the flexible back timber 3, place passing jack 5 and scraper plate elevating conveyor tail 6 on the bracket base 1, described bracket upright post 4 places the back of scraper plate elevating conveyor tail 6.Be provided with spoil baffle plate 9 in the front of bracket upright post 4, the bottom of spoil baffle plate 9 places between scraper plate elevating conveyor tail 6 and the bracket upright post 4 and is connected with bracket base 1.Also be provided with spoil baffle plate 8 above the described spoil baffle plate 9, last spoil baffle plate 8 upper ends flexibly connect by engaging lug 10 and flexible back timber 3, and the lower end rides over the external surface of spoil baffle plate 9.
End hydraulic support of the prior art is used for the large tilt angle compound mining work plane, its scraper plate elevating conveyor tail 6 is positioned at the rear side of bracket upright post 4, after work plane drag conveyor head 7 produces coal, coal drops on the scraper plate elevating conveyor tail 6, scraper plate elevating conveyor transhipment coal produces to the flexible conveyor of DSJ, and face end support column 4 is when being positioned at scraper plate elevating conveyor tail 6 fronts, coal is after work plane drag conveyor head 7 comes out, directly impact bracket upright post 4, fall on scraper plate elevating conveyor tail 6 by bracket upright post 4, this kind mode makes bracket upright post 4 often be hit, life-span greatly reduces, because face end support column 4 is the support that turns forward, make face end support be easy to generate support and prick end phenomenon, particularly be under the softer or old man's ponding serious situation of machine lane base plate, in case after face end support is pricked the end, when force piece advanced, face end support then can't normally advance.
The utility model is applied to green coal 5654 high-dipping fully-mechanized mining workings, end hydraulic support is positioned at the work plane lower end, supporting with force piece, end hydraulic support is connected with scraper plate elevating conveyor tail 6, and end hydraulic support is over against work plane drag conveyor head 7, when coal is transported to elevating conveyor tail 6 by work plane conveyer head 7, be transported on the scalable rubber conveyer by elevating conveyor and transport, bracket upright post 4 of the present utility model is installed in scraper plate elevating conveyor tail 6 back, there is waste rock board 8 and 9 to separate therebetween, to prevent that coal from breaking bracket upright post 4 when work plane falls, and bracket upright post 4 postposition support occurs and prick end phenomenon in the time of can be because of bracket upright post 4 stressed supports.After bracket upright post 4 postposition, the pedestrian from bracket upright post 4 back by also having very high safety, because the pedestrian space has increased a lot.
