Description
Technical field
The present invention relates to technical field of coal mine, particularly a kind of safe defense-help network of driving face in coal mine split blade type.
Background technology
At this stage, wall caving refer to mine, tunnel, culvert excavate, during lining cutting because excavating or supporting is improper, side wall is in ore deposit
Mountain pressure effect is lower to be deformed, the phenomenon destroyed and come off.On-site actual situations take the circumstances into consideration one or to play the post reinforcement of patch side every a dozen
Supporting, helped if necessary with small backboard.Structural strength is low and its installation expends more time, and installation effectiveness is low.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art, there is provided a kind of driving face in coal mine split blade type is anti-safely
Wall caving net.The present invention uses following technical scheme to achieve the above object：
A kind of safe defense-help network of driving face in coal mine split blade type, it is characterised in that including ladder-shaped frame, horizontal gird, add
Strengthening tendons, adjustment plate, protection network, column, bradyseism frame, ladder-shaped frame upper end level have welded horizontal gird, and horizontal gird is built-in to be welded
Reinforcement, the adjustment plate bolt connection ladder-shaped frame side support bar of horizontal gird both sides welding, the installation of horizontal gird bolt are connect
Column hung protection network, ladder-shaped frame bottom bolt is mounted with bradyseism frame.
Preferably, the bradyseism frame by mounting blocks, bradyseism column, middle standing pillar and bradyseism shim pack into before and after mounting blocks
End is mounted with bradyseism column, and mounting blocks center has welded middle standing pillar, bradyseism pad has been set with middle standing pillar.
Preferably, the column is drilled with multigroup mounting hole, and the mounting hole bolt of column is mounted with to link up with.
Preferably, the fire-retardant material braiding of the protection network material selection.
Compared with prior art, the present invention has advantages below：A kind of driving face in coal mine split blade type anti-wall caving safely
Net, present apparatus design is applied to the safety work in ore deposit machine tunnel, in use, ladder-shaped frame is fixed on pit barring, mine
Bracket support tunnel prevents tunnel from caving in, and protection network encloses formed section and matched with drift section, and is close to meet head on
End face, the coal on the wall of tunnel lane drop in protection network, and so as to ensure that the security of operating personnel, the design of bradyseism frame makes
The present apparatus possesses certain bradyseism performance.
