Abstract
The invention provides a multi-step-pitch band tail beam supporting-type filling hydraulic support. A back telescopic beam and a telescopic part are arranged inside an open-type box body at the back end of a back upper beam of the support. Under the effect of the telescopic part, the back upper beam and the back telescopic beam generate relative motion. The back end of the back telescopic beam is provided with a tail beam in a hinged mode. After a coal mining part of the support moves forward, the whole support generates multiple step pitches by the back telescopic beam and the tail beam supporting a top plate. A telescopic plugging plate is hinged on the lower portion of the tail beam, a supporting part is arranged between the telescopic plugging plate and the back telescopic beam, and the telescopic plugging plate can be used for adjusting a swing angle under the effect of the supporting part. The multi-step-pitches band tail beam supporting-type filling hydraulic support not only can support the top plate when be used for mining the coal, but also can achieve filling of a worked-out section, and achieves integration of support filling.

Background technology
Rich coal resources in China, fully-mechanized mining equipment is ripe, coal winning technology is gradually improved, in short supply along with the energy, the quickening day by day of coal in China exploitation paces, increasing mine is faced with the resource exhaustion problem, presses the coal problem for solving " three times ", China presses coal by adopting traditional band exploitation, the multiple technologies measures such as village, filling mining of moving to liberate " three times ", improves coal mining rate.But along with the increase of mining depth, the raising of the increase of village migration cost and filling technique technological level, the filling mining technology has become flourish gesture.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of performing comprehensive coal mining supporting and fills integrated multi-pace band tail boom brace type filling hydraulic support.
For solving the problems of the technologies described above, the invention provides a kind of multi-pace band tail boom brace type filling hydraulic support, be provided with rear extensible canopy and extensible member in the casing of the rear top beam rear end open type of described support, under the effect of extensible member, rear back timber and rear extensible canopy produce relative motion, and described rear extensible canopy rear end is hinged with tail boom, after the coal mining of described support partly moves forward, by rear extensible canopy and tail boom roof supporting, make whole support produce a plurality of step pitches; Be hinged with flexible plate under described tail boom, be provided with support component between described flexible plate and rear extensible canopy, flexible plate can be adjusted pendulum angle under the effect of described support component.
Further, described tail boom carries out angular adjustment by the tail boom jack that is hinged on rear extensible canopy and tail boom.
Further, described flexible plate flexible under the flexible jack effect of plate.
Further, design end boots in the lower end of described flexible plate under the flexible jack effect of plate, strengthen enabling capabilities to top board by tail boom.
Further, described extensible member is flexible jack.
Further, described support component is the plate jack.
Further, the front back timber of described support, column, balance jack, upper connecting rod, rear back timber, base, back link, front rod, passing frame and advancing jack complement each other to form four basic post hydraulic supports, play basic the coal mining and the supporting roof effect.
Further, described balance jack is hinged between front back timber and upper connecting rod.
Further, described balance jack is hinged between rear back timber and upper connecting rod.
Further, described balance jack is hinged between front back timber and rear back timber.
A kind of multi-pace band tail boom brace type filling hydraulic support provided by the invention to the supporting of top board, can also be realized the filling in goaf in the time of not only can playing coal mining, has realized that the supporting filling is integrated.
Description of drawings
After the multi-pace band tail boom brace type filling hydraulic support that Fig. 1 provides for the embodiment of the present invention, back timber and rear extensible canopy are in the schematic diagram of contraction state.
After the multi-pace band tail boom brace type filling hydraulic support that Fig. 2 provides for the embodiment of the present invention, back timber and rear extensible canopy are in the schematic diagram of extended state.
The specific embodiment
referring to Fig. 1 and Fig. 2, a kind of multi-pace band tail boom brace type filling hydraulic support that the embodiment of the present invention provides, be provided with rear extensible canopy 6 and extensible member in the casing of the rear back timber 5 open rearward end formulas of hydraulic support, in the present embodiment, a kind of concrete implementation as extensible member, extensible member is flexible jack, under the effect of extensible canopy jack, rear back timber 5 produces relative motion with rear extensible canopy 6, rear extensible canopy 6 rear ends are hinged with tail boom 8, tail boom 8 can be regulated certain angle by the tail boom jack 7 that is hinged on rear extensible canopy 6 and tail boom 8, after the coal mining of hydraulic support partly moves forward, by rear extensible canopy 6 and tail boom 8 roof supportings, make whole support produce a plurality of step pitches, tail boom is hinged with flexible plate 9 for 8 times, flexible plate 9 certain distance that can stretch under the flexible jack effect of plate, be provided with support component between rear extensible canopy 6 and flexible plate 9, in the present embodiment, a kind of concrete implementation as support component, support component is plate jack 10, and flexible plate 9 can swing certain angle under the effect of plate jack 10, have certain compliance.
Wherein, the lower end of flexible plate 9 is designed with end boots 15, under the flexible jack effect of plate, can strengthen enabling capabilities to top board by tail boom 8.
The front back timber 1 of hydraulic support, column 2, balance jack 3, upper connecting rod 4, rear back timber 5, base 11, back link 12, front rod 13, passing frame and advancing jack 14 complement each other to form four basic post hydraulic supports, play basic the coal mining and the supporting roof effect.
Wherein, balance jack 3 is hinged between front back timber 1 and upper connecting rod 4, and balance jack 3 also can be hinged between rear back timber 5 and upper connecting rod 4.Balance jack 3 also can be hinged between front back timber 1 and rear back timber 5.
Wherein, passing frame and advancing jack 14 are positioned between base 11 crotch, and passing frame one end is connected with the main transporter of adopting face, and an end is connected with base by advancing jack, play a part pushing and sliding and move frame and work frame and the pushing and sliding effect of moving.
The operating principle of a kind of multi-pace band tail boom brace type filling hydraulic support provided by the invention is as follows:
The supporting part of hydraulic support is the same with the effect of conventional hydraulic bracket support, as follows in the filling part implementation procedure: take the tail boom 8 of this hydraulic support rear end and flexible plate 9 as baffle plate, coordinate other transition brackets, add the goaf, form the space of a sealing, thereby realize the filling to goaf lotion (Gao Shui); The rear extensible canopy 6 of back timber 5 rear ends is bridge later on, support front end a plurality of step pitches of can mining, by stretching of rear extensible canopy 6, the support of adaptation to top board, then after having adopted repeatedly coal, rear extensible canopy 6 is regained, and after driving, the tail boom 8 at extensible canopy 6 rear portions, flexible plate 9 etc. move forward together, for next filling is prepared.
