Technical field
The present invention relates to underground coal mine fully-mechanized coalface support apparatus technical field, particularly a kind of multi-pace band tail boom brace type filling hydraulic support.
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 resource exhaustion problem, for solving " three times " pressure coal problem, coal mining rate, by adopting traditional Striping noise, resettlement multiple technologies measure liberation such as village, filling mining " three times " pressure coal, improves in China.But along with the increase of mining depth, the increase of village migration cost and the raising of filling technique technological level, 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, rear extensible canopy and extensible member is provided with 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 part of described support moves forward, by rear extensible canopy and tail boom roof supporting, whole support is made to produce multiple step pitch; 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 adjust pendulum angle under the effect of described support component.
Further, described tail boom carries out angular adjustment by the tail boom jack be hinged on rear extensible canopy and tail boom.
Further, described flexible plate flexible under the effect of plate telescopic jack.
Further, boots at the bottom of the lower end design of described flexible plate, under the effect of plate telescopic jack, strengthen the enabling capabilities to top board by tail boom.
Further, described extensible member is telescopic jack.
Further, described support component is 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 coal mining and 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, the supporting to top board when not only can play coal mining, can also realize the filling in goaf, achieves supporting and fills integration.
Accompanying drawing explanation
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.
Detailed description of the invention
See 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, rear extensible canopy 6 and extensible member is provided with in the casing of the rear back timber 5 open rearward end formula of hydraulic support, in the present embodiment, as a kind of concrete implementation of extensible member, extensible member is telescopic 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 end is hinged with tail boom 8, tail boom 8 can regulate certain angle by the tail boom jack 7 be hinged on rear extensible canopy 6 and tail boom 8, after the coal mining part of hydraulic support moves forward, by rear extensible canopy 6 and tail boom 8 roof supporting, whole support is made to produce multiple step pitch, tail boom is hinged with flexible plate 9 for 8 times, flexible plate 9 can stretch certain distance under the effect of plate telescopic jack, support component is provided with between rear extensible canopy 6 and flexible plate 9, in the present embodiment, as a kind of concrete implementation of support component, support component is plate jack 10, and flexible plate 9 can swing certain angle under the effect of plate jack 10, has certain compliance.
Wherein, the lower end of flexible plate 9 is designed with end boots 15, under the effect of plate telescopic jack, can strengthen the 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 coal mining and 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 adopting face, and one end is connected with base by advancing jack, play a part pushing and sliding and move frame and play and move frame and pushing and sliding effect.
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 retaining portion of hydraulic support is the same with the effect of conventional hydraulic bracket support, as follows in filling part implementation procedure: with the tail boom 8 of this hydraulic support rear end and flexible plate 9 for baffle plate, coordinate other transition brackets, add goaf, form a closed space, thus realize the filling to goaf lotion (Gao Shui); The rear extensible canopy 6 of later back timber 5 rear end is bridge, can mine multiple step pitch in support front end, stretching by rear extensible canopy 6, adapt to the support to top board, then after having adopted repeatedly coal, rear extensible canopy 6 is regained, and after driving, the tail boom 8, flexible plate 9 etc. at extensible canopy 6 rear portion moves forward, together for next filling is prepared.
It should be noted last that, above detailed description of the invention is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to example to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
