Description
Technical field
The utility model is related to a kind of timbering technology in coal mine fields, and in particular to a kind of underground combined type wall supporting net.
Background technology
In underground coal mine recovery process, portion of side or head-on wall slabbing is hurted sb.'s feelings, it is necessary to coordinate by strut in order to prevent
Wall supporting net protects portion of side, traditional wall supporting net be usually protected using polylith bar-mat reinforcement, bar-mat reinforcement by width because
Element limitation often requires to use tied silk connection and is spliced, it is easy to which it is not in place local area protection occur, is not achieved expected anti-
Protect effect；In addition existing bar-mat reinforcement is often transported to working face in rolls, and scene is needed to cut suitable dimension, Ran Houxu before use
Manually spliced with tied silk, operate and be inconvenient, and influence work efficiency.Therefore, it is necessary to design a kind of underground combined type
Wall supporting net, to solve the problems, such as that existing wall supporting net exists.
The content of the invention
In order to solve the above technical problems, the utility model provide it is a kind of simple in structure, it is easy to operate, existing shield can be solved
Help the underground combined type wall supporting net of net installation operation inconvenience problem.
The utility model is realized by following technical proposals：
A kind of underground combined type wall supporting net, including：Multiple wall supporting net units, each wall supporting net unit include rectangular frame and
Bar-mat reinforcement；Rectangular frame is welded by angle bar, and bar-mat reinforcement is weldingly fixed on rectangular frame；Between adjacent wall supporting net unit
It is hinged.
Further, the upper and lower part of the rectangular frame both sides of each wall supporting net unit is respectively fixedly connected with horizontal company
Lug；Adjacent wall supporting net unit through the safety pin of two neighboring engaging lug inner via hole by being hinged.In use, use safety pin
Wall supporting net unit is articulated and connected successively, while is also prevented from wall supporting net axis pin in protection process and extracts, it is ensured that is safe to use.
During driving, safety pin need to only be extracted, the storage of wall supporting net folding hangs over portion of side.
Further, the surface of the bar-mat reinforcement of each wall supporting net unit is fixedly connected with a support ring.Support ring can match somebody with somebody
Wall supporting net strut is closed, support ring is withstood in wall supporting net strut one end, and the support to wall supporting net is realized, to reach in other end country rock top
To the protection to portion of country rock side.
The utility model has the advantage that compared with prior art：The utility model is simple in structure, easy to operate, pass through by
Bar-mat reinforcement, which is welded on the rectangular frame being made of angle bar, forms wall supporting net unit, then wall supporting net unit is hingedly formed sheet of
Wall supporting net, operator simply easily operate very much, and hard use tied silk splice bar net is not required, and greatly improve work effect
Rate and labor intensity.In driving, safety pin need to only be extracted, the storage of wall supporting net folding hangs over portion of side, and wall supporting net can be with
It repeatedly uses, and has saved the operating space of working face, effectively solve traditional bar-mat reinforcement and splice not in place and installation
The problem of inconvenient.

Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments, so as to skill in the art
Art personnel understand the utility model.
A kind of underground combined type wall supporting net, including：Multiple wall supporting net units 8, each wall supporting net unit 8 include rectangular frame
1 and bar-mat reinforcement 2；Rectangular frame 1 is welded by angle bar, and bar-mat reinforcement 2 is weldingly fixed on rectangular frame 1；Adjacent wall supporting net
It is hinged between unit 8.The upper and lower part of 1 both sides of rectangular frame of each wall supporting net unit 8 is respectively fixedly connected with horizontal company
Lug 3；Adjacent wall supporting net unit 8 is hinged by the safety pin 4 through two neighboring 3 inner via hole of engaging lug.Each wall supporting net
The surface of the bar-mat reinforcement 2 of unit 8 is fixedly connected with a support ring 5.
In use, wall supporting net unit 8 is hinged to full wafer wall supporting net successively using safety pin 4, on each wall supporting net unit 8
Support ring 5 is fixed with, support ring 5 can coordinate wall supporting net strut 6, and support ring 5, other end top are withstood in 6 one end of wall supporting net strut
At the top of portion's country rock, the support to wall supporting net is realized, to reach the protection to portion of country rock side 7.
The above is only the preferable specific embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality
New technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
