Further, be provided with chute in the described rear back timber, being equipped with in the described chute plays fills the supporting plate of transporter, and described supporting plate slides in chute under the effect of the supporting plate jack of rear back timber inside.
Further, described base tail end is hinged with balance arm, and column, front-rear linkage are installed on it.
Further, described passing frame is installed between the base crotch, and passing frame one end links to each other with the main transporter of adopting face, and an end links to each other with bracket base by advancing jack, plays a part pushing and sliding and moves frame.
Further, described upper balance arm adopts body structure, and its end part is hinged with the rear top beam rear end ears or side handles of a utensil, and an end and upper balance arm jack are hinged, in upper balance arm jack effect lower swing angle.
Further, described balance arm or upper balance arm be according to support height and the requirement of balance arm magnification, adopts the flexible balance arm of single-stage, twin-stage balance arm mechanism or multistage balance arm mechanism.
Further, the described hinged face guard of front back timber front end and extensible canopy mechanism.
Further, in described balance arm or the upper balance arm, the extensible canopy Front-end Design becomes the shovel board structure at angle of inclination
The utility model is compared existing hydraulic support and has been compared following difference:
Forward and backward back timber, base, balance jack and quadric chain in the utility model can play the roof timbering effect of traditional fully mechanized coal face, is a requisite ingredient therefore.
Be the function that can realize filling better, position unique design suitable on rear back timber has otic placode, and the balance arm jack can be installed, thereby can and allow balance arm be in suspension status by balance arm jack push-and-pull balance arm; The balance arm jack is hinged with rear back timber and balance arm respectively up and down, up-down adjustment balance arm under its effect; The hinged end of balance arm is articulated in the base rear portion.
When the balance arm of support below can not be put certain altitude, in order to realize better filling effect, in rear top beam rear end unique design on balance arm mechanism, under upper balance arm jack telescopic action, balance arm swings certain angle in the promotion, thereby can realize the filling on top, goaf, thereby make filling effect better.
In sum, to the supporting of top board, can also realize the filling in goaf when the utility model not only can play coal mining, realize that the supporting filling is integrated.

The specific embodiment
The utility model is done with detailed description below with reference to example (accompanying drawing):
As shown in Figure 1, 2, the utility model four post double-swing-beam type gangue filling hydraulic supports, this hydraulic support comprise the compositions such as connecting rod 2, rear back timber 3, column 4, balance jack 5, balance arm 6, balance arm jack 7, back link 8, front rod 9, base 10, passing frame and advancing jack 11 on front back timber 1, the Y type, upper balance arm jack 12, upper balance arm 13.Column 4 be supported on forward and backward back timber 1,3 and base 10 between; Connecting rod 2 upper ends are hinged on forward and backward back timber 1,3 the pin joint on the Y type, form the unique texture of 3 unifications, connecting rod 2 is hinged with an end of back link 8 with front rod 9 respectively on the Y type simultaneously, described front rod 9 is hinged with the other end and the base 10 of back link 8, connecting rod 2, front rod 9, back link 8 and the base 10 formation four-bar linkage structure that is hinged in twos on the Y type; Balance jack 5 is connected to be used between the connecting rod 2 on front back timber 1 and the Y type regulating and keeps front back timber attitude; Rear back timber 3 is hinged on front back timber 1 afterbody, under the effect of column 4, can support the goaf, in the chute on rear back timber 3 supporting plate is installed, the filling transporter plays on the supporting plate, supporting plate slides in chute under the effect of the supporting plate jack of rear back timber 3 inside, suitable Position Design has otic placode on the rear back timber 3, and balance arm jack 7 can be installed, thereby can allow balance arm 6 be in suspension status by balance arm jack 7; Balance arm 6 hinged with base 10 rear ends, its top is hinged with the balance arm jack 7 that is installed on the rear back timber 3, can swing up and down certain angle under 7 effects of balance arm jack, thus charges that can each position of filling; Balance arm jack 7 is hinged with rear back timber 3 and balance arm 6 respectively up and down, up-down adjustment balance arm 6 under 7 effects of balance arm jack; The ears or side handles of a utensil of upper balance arm jack 12 1 ends and rear back timber 3 rear ends are hinged, and the hinged and upper balance arm of an end 13 is hinged, by its telescopic action, can push-and-pull on balance arm 13 swing certain angles; Upper balance arm 13 adopts body structure, and its end part is hinged with the rear back timber 3 rear end ears or side handles of a utensil, and an end and upper balance arm jack 12 are hinged, at upper balance arm jack 12 effect lower swing certain angles; Base 10 tail ends are hinged with balance arm 6, and column 4, front-rear linkage 9,8 etc. are installed on it; Passing frame is installed between base 10 crotch, and passing frame one end links to each other with the main transporter of adopting face, and an end links to each other with bracket base by advancing jack, plays a part pushing and sliding and moves frame.
Operating principle of the present utility model is as follows:
The supporting part of support is the same with the effect of conventional hydraulic bracket support, as follows in the filling part implementation procedure: as to hang the goaf that the supporting plate of filling transporter slides into needs filling in the chute at rear back timber under the effect of supporting plate jack, filling transporter transportation filler and fill the goaf; The balance arm that is hinged on the base is adjusted to certain elevation angle under the push-and-pull action by the balance arm jack on the back timber after being hinged on, have under the compacting jack effect in the balance arm to promote extensible canopy again, and charges are carried out the tamping filling; When the balance arm of support below can not be put certain altitude, in order to realize better filling effect, in rear top beam rear end unique design ground balance arm mechanism, under upper balance arm jack telescopic action, balance arm swings certain angle in the promotion, thereby can realize the filling on top, goaf, thereby make filling effect better.
Minimum when the highest at support, balance arm minimax angular range is 0 °-50 °; And in its working depth scope, balance arm minimax angular range is 5 °-40 °; When support is worked when filling (mine), the maximum angle of balance arm be balance arm topmost along with rear scratch board conveyor bottom along tangent, minimum angles is decided according to concrete actual conditions.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
