Abstract
The utility model discloses a double-stage side protecting device for comprehensive mechanized coal mining and large mining height working face transition supports, which comprises a top beam large side board and a shield beam large side board which are welded on the same side of a hydraulic support top beam and a shield beam, and a top beam movable side board and a shield beam movable side board which are hinged on the other side of the hydraulic support top beam and the shield beam. The top beam movable side board and the shield beam movable side board are respectively provided with side-thrusting jacks which are hinged with the hydraulic support top beam and the shield beam. The lower edge of the top beam large side board of the box-type structure is horizontally hinged with a lower side board of the integral structure through connecting lugs, and the lower side board is provided with a supporting jack which is hinged with the top beam large side board. The double-stage side protecting device has the advantages of realizing the safe protection of large height drop areas between a middle support and end supports, and achieving the aims of effectively recycling triangle coals on two lateral sides of the large mining height working face and improving the recovery rate of coals.
Description
Technical field
The utility model relates to the suspension device of the big mining height of coal mine fully-mechanized mining working, especially relates to being suitable for the comprehensive twin-stage side protection unit of adopting the large-mining-height working surface transition bracket of coal.
Background technology
The fully-mechanized mining equipment primary recovery height that has used in the colliery is many seven meters left and right sides, and along with the development exploitation of combining the technology of adopting highly improves constantly.The roadway workface height is tunneled, the restriction of support apparatus, highly generally about four meters, highly again will sharply increase labour intensity and have certain potential safety hazard.Therefore, tunnel and work plane just have a bigger difference in height.Existing transient mode is to reduce gradually by several even tens hydraulic supports highly to realize slow transition, this just makes and leaves coal district, triangle top at top, work plane two ends, caused certain wasting of resources, and along with the raising waste of exploitation height is more and more serious.
Summary of the invention
The utility model purpose is to provide a kind of coal that is suitable for to combine the twin-stage side protection unit of adopting the large-mining-height working surface transition bracket, to solve transition bracket and the big discrepancy in elevation protection question of face end support.
For achieving the above object, the utility model can be taked following technical proposals:
The coal that is suitable for described in the utility model is combined the twin-stage side protection unit of adopting the large-mining-height working surface transition bracket, the big side plate of back timber, the big side plate of caving shield that comprise the box-structure that is welded in hydraulic support back timber, caving shield the same side, with the movable side plate of the back timber that is articulated in described hydraulic support back timber, caving shield opposite side, the movable side plate of caving shield, on the movable side plate of described back timber, the movable side plate of caving shield, be respectively arranged with and be used for the thruster jack that is hinged with hydraulic support back timber, caving shield; The big side plate of back timber lower edge at described box-structure is hinged with integrally-built lower side panel by engaging lug, and described lower side panel is provided with the support jack that is hinged with the big side plate of back timber.
The utility model advantage is to realize the security protection in the big zone of work plane intermediate support and face end support supporting height drop, reaches the purpose of lane, effective recovery large-mining-height working surface both sides ventral triangle coal, raising coal recovery rate.When work plane is arranged hydraulic support, big side plate of back timber and face end support side guard board overlap joint with described box-structure, can use the big side plate of back timber separately or be used in combination according to the mining height difference with integrally-built lower side panel, be beneficial to large-mining-height working surface and just gone out to cut a mining height and dodge transporter and coal-winning machine when low, the movable side plate of the back timber of described box-structure is overlapped with intermediate support get final product then.
