Abstract
The utility model discloses a single-grade side protecting device for a transition support of a comprehensive large-mining high working surface, comprising a top beam large side plate and a cover beam large side plate of a box-shaped structure, welded at the same side of a top beam and a cover beam of a hydraulic support, and a top beam movable side plate and a cover beam movable side plate hinged with the other side of the top beam and the cover beam of the hydraulic support; the top beam movable side plate and the cover beam movable side plate are respectively provided with side pushing jacks hinged with the top beam and the cover beam of the hydraulic support. The single-grade side protecting device for the transition support has advantages that the region with large supporting height difference between a middle support and an end support of the working surface can be protected safely, so that triangular coal at two sides of the large-mining high working surface is effectively recycled, the recycling rate of coal is improved. When the working surface is provided with the hydraulic support, the top beam large side plate of the box-shaped structure is overlapped with the end support side protecting plate, and the top beam movable side plate of the box-shaped structure is overlapped with the middle support.
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 single-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 7 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 4 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 single-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 single-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 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 was arranged hydraulic support, big side plate of back timber and face end support side guard board overlap joint with described box-structure got final product movable side plate of the back timber of described box-structure and intermediate support overlap joint.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the coal that is suitable for described in the utility model is combined the single-stage side protection unit of adopting the large-mining-height working surface transition bracket, the big side plate 1 of back timber, the big side plate 2 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 3 of the back timber that is articulated in described hydraulic support back timber, caving shield opposite side, the movable side plate 4 of caving shield, on the movable side plate 3 of described back timber, the movable side plate 4 of caving shield, be respectively arranged with and be used for the thruster jack that is hinged with hydraulic support back timber, caving shield.
Claims (1)
