The concrete structure of further improvement of the utility model is: on the pin joint of front back timber and rear back timber also hinged one height-adjustable on connecting rod, upper connecting rod forms quadric chain together with base, front rod, back link, and front rod, back link are hinged on base; In the middle part hinged of the upper connecting rod balance jack hinged with front back timber.
The concrete structure of further improvement of the utility model is: described face guard comprises one-level face guard and secondary protecting side plate, one-level face guard is connected to the front end of front back timber, the front end of the hinged one-level face guard of secondary protecting side plate, between one-level face guard and front back timber, be hinged with the one-level wall supporting jack that lifts or regain one-level face guard, below one-level face guard, be provided with the secondary protecting side jack for secondary protecting side plate lifted or put down hinged with secondary protecting side plate.
The concrete structure of further improvement of the utility model is: in base, be provided with advancing jack and passing frame, advancing jack is connected with passing frame, passing frame front end is provided with the cross head being connected with coal-winning machine and drag conveyor, relies on the flexible realization of advancing jack to pass forward coal-winning machine and drag conveyor and pull support reach.
The concrete structure of further improvement of the utility model is: the elongation of described flexible jack is the twice or three times of advancing jack stroke.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model is propped front back timber, rear back timber by two telescopic columns, withstands on the top in goaf, realizes while mining the supporting of coal-winning machine and drag conveyor and the supporting to packing job.Support of the present utility model can make coal mining activity and packing job carry out simultaneously, front back timber before support and face guard can carry out supporting to coal mining region and rib, rear back timber and rear extensible canopy can be in coal mining activities above, the end face in goaf is below supported and carries out filling and support, can realize support front portion in coal mining supporting, packing job is carried out at support rear portion simultaneously, greatly improved coal mining and pack effectiveness, be applicable to full-seam mining and need the work plane of filling.
Brace summer on rear extensible canopy, when packing job, by retaining device, prop up the end support top, make support to goaf, treat that the support degree of end face of filling is larger, be convenient to high water rapidly solidified material Jin Shuhuohejinrongtiyi104～106℃/s satchel form firm solid below rear extensible canopy, retaining device can support brace summer when packing job, the material being filled in below rear extensible canopy is isolated with the part of mining above simultaneously.
The quadric chain and the balance jack that are hinged on the pin joint of front back timber and rear back timber can also be adjusted front back timber and rear back timber angle in the horizontal direction, with adapt to the top height in goaf different, be not the situation of plane.The face guard arranging at the front end of front back timber, for the rib supporting to bank; And face guard consists of two sections of one-level face guard and secondary protecting side plates, when coal-winning machine and support-moving of the present utility model are during to coal mining position, supporting is carried out at the top that before first using, back timber is split exploiting field, and now face guard is regained the rib of supporting bank downwards.When coal-winning machine completes an operation cycle, the advancing jack of support moves forward a step pitch by drag conveyor and coal-winning machine, and then pulls support forward, carries out next one coal mining circulation.Now, rear flexible jack stretches out the stroke of a step pitch, and under extensible canopy jack and baffle plate and support beam action, rear extensible canopy and baffle mechanism stay put, to guarantee that the fill paste of rear extensible canopy bottom solidifies.
Be arranged on the rear extensible canopy of the rear end of rear back timber, for the supporting of stowing operation.In rear extensible canopy stowing operation, inject backward above extensible canopy high water rapidly solidified material Jin Shuhuohejinrongtiyi104～106℃/s, high water rapidly solidified material Jin Shuhuohejinrongtiyi104～106℃/s is frozen into the solid with some strength very soon, and the top board in goaf is formed and supported, and realizes the filling to goaf.When coal mining finishes to pull support reach, when keeping support reach, stretch out rear flexible jack, because rear extensible canopy is supported on top, rear extensible canopy and baffle plate can continue to stay original position, do not affect solidifying of obturation.Two step pitches or 3 step pitches that after the utility model design, effective stroke of extensible canopy is advancing jack, adopt two cutter coals or three cutter coals, support moves forward two or three times, and rear extensible canopy pulls forward once, to guarantee that high water rapidly solidified material Jin Shuhuohejinrongtiyi104～106℃/s solidifies fully completely.After high water rapidly solidified material Jin Shuhuohejinrongtiyi104～106℃/s fully solidifies, the supporting role of retaining device is removed (shrink plate jack), rear flexible jack is shunk, rear extensible canopy is moved forward and is close to rear back timber, and again carry out filling next time, supporting operation.Face guard and rear extensible canopy are used in conjunction with, and can realize the operation effectiveness of " two adopt fills " or " three adopt fills ".
Front column and rear column are designed to multi-stage expansion oil cylinder can carry out supporting to the end face of differing heights.Quadric chain can be by the front back timber of flexible adjustment of balance jack and the angle between rear back timber, to adapt to the supporting of the end face that is not plane.
The plate of retaining device of the present utility model supports to vertically downward bottom surface under the effect of plate jack, rear extensible canopy is formed to stable support, make rear extensible canopy prop up the top board in goaf, the end face in rear extensible canopy end face and goaf forms box board effect, high water rapidly solidified material Jin Shuhuohejinrongtiyi104～106℃/s injects, and forms the thickness with supporting role.The support point of plate lower end can be inserted on bottom surface.
