Abstract

The invention discloses a single-stage side protective device applicable to a high working surface transition support in mechanized mining and deep mining of coal, comprising a large top beam side plate and a large shield beam side plate which are welded at the same side of a hydraulic support top beam and a shield beam and are in a box-type structure as well as a movable top beam side plate and a movable shield beam side plate which are hinged with the other side of the hydraulic support top beam and the shield beam, and side thrusting jacks used for being hinged with the hydraulic support top beam and the shield beam are respectively arranged on the movable top beam side plate and the movable shield beam side plate. The invention has the advantages that safe protection of a high supporting height fall region of a middle support and an end support in a working surface is realized and the aims of effectively recycling triangle coals at the top of lanes at the two sides of the working surface in deep mining and improving the recovery rate of the coal are achieved. When a hydraulic support is arranged on the working surface, the large top beam side plate in the box-type structure is overlapped with an end support side protective plate, and the movable top beam side plate in the box-type structure is overlapped with the middle support.

Description

Be suitable for coal and combine the single-stage side protection unit of adopting the large-mining-height working surface transition bracket
Technical field
The present invention relates to the suspension device of the big mining height of coal mine fully-mechanized mining working, especially relate to and be suitable for coal and combine the single-stage side protection unit adopt the large-mining-height working surface transition bracket.
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 object of the invention 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 present invention can take following technical proposals:
The coal that is suitable for of the present invention 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 invention has the advantages that the security protection that realizes the big zone of work plane intermediate support and face end support supporting height drop, reach 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 invention.
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 of the present invention 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)

1. one kind is suitable for the comprehensive single-stage side protection unit of adopting the large-mining-height working surface transition bracket of coal, it is characterized in that: the big side plate of back timber (1), the big side plate of caving shield (2) 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 of caving shield (4), be respectively arranged with and be used for the thruster jack that is hinged with hydraulic support back timber, caving shield.
