The refractory slab is fixed on the back timber of three-dimensional portal support by cushion block.
The column and knee type gang drill, is that at least two top jumbolters and at least two side anchor poles are fixed with lifting platform
Rig is formed.
The both sides of the three-dimensional portal support are at least provided with two groups of adjustment direction hydraulic cylinders.
The two ends column of the three-dimensional portal support is provided with road wheel.
Compared with prior art, the invention has the advantages that：1st, for temporary support for drivage face, it is capable of achieving
The mechanization of gib, is greatly enhanced the security and drivage efficiency of gib.2nd, face in advance for coal-face
When supporting, can effectively solve the problems, such as advanced falsework extrude repeatedly cause roof cracking, anchor shaft anchor cable fail, further carry
Security of superb preceding gib etc..

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described.Obviously, described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
A kind of canopy formula with gang drill is taken a step sectional shelf-unit, including three-dimensional portal support 1, refractory slab 2, connecting rod 3 and lifting platform
Formula gang drill；1 point of three-dimensional portal support is odd number frame and even number frame, and odd number frame or even number frame are connected by refractory slab 2 be combined into respectively
Integrally, odd number frame, even number frame are connected by elapsing hydraulic cylinder 12 and connecting rod 3；Column and knee type gang drill by elapse hydraulic cylinder 4 with
The rear portion of three-dimensional portal support 1 connects.
Three-dimensional portal support 1 is welded with crossbeam 10 and forms by two portal supports, the lower end connection of the column of three-dimensional portal support 1
There is column hydraulic cylinder 13, three-dimensional portal support 1 has stability and mechanical strength higher.
Refractory slab 2 is formed by the riveting of at least two-layer steel spring plate, and the outer layer plate gap at joint of refractory slab 2 is smaller to be beneficial to cunning
Dynamic, middle sandwich of layers steel plate disconnects adapting to top board fluctuating.
Refractory slab 2 is fixed on the back timber of three-dimensional portal support 1 with bolt by cushion block 14；And in three-dimensional portal support 1
Two ends form one section of cantilever beam.
The cushion block 14 being staggered is welded with odd number frame and even number frame, the effect of cushion block 14 is for drop frame reserves sky
Between, when can so ensure that odd number frame declines, refractory slab 2 is ridden on the back timber of even number frame, and vice versa.
The column lower end at the two ends of three-dimensional portal support 1 is provided with road wheel 11, is easy to three-dimensional portal support 1 to take a step to move frame and branch
Support.
As shown in Fig. 1~2：Three-dimensional portal support 1, refractory slab 2 are transported into driving face, with whole refractory slab 2 by solid
1 point of odd number frame of portal support, even number frame are sequentially connected, then install connecting rod 3 successively；With passage hydraulic cylinder 12 by three-dimensional gate-type branch
The odd number frame of frame 1, the connection of even number frame are combined into one；Adjustment direction hydraulic cylinder 8 is installed, in support upper berth anchor net；By lifting platform
Formula gang drill is assemblied in the rear end of three-dimensional portal support 1；Connect hydraulic tube, hydraulic power unit, control system.
Start pumping plant, after adjusting three-dimensional portal support 1 by adjustment direction hydraulic cylinder 8 and angle adjustment hydraulic cylinder 9, will be strange
Several framves hold out against；The reach of even number frame is held out against after odd number frame using hydraulic cylinder 12 is elapsed；Frame, reach, top are dropped into odd number frame again
Tightly；So circulation, holds out against, away from termination distance not influenceing development machine until sectional shelf-unit is proceeded to away from driving termination suitable distance
Shaping to top board and lane side is limited.
Connect the anchor net that continues；Start development machine and start operation, after one supporting step pitch of driving, support takes a step to move forward one
Step pitch；Start top jumbolter 6, permanent support is carried out to top board；Restart side jumbolter 7, permanent support is carried out to lane side；
So circulation, realizes driving, linked network, moves frame, supporting parallel operations.
Column and knee type gang drill is ridden on development machine transfer chute, and when platform rises, development machine can be passed through；Rise
The power that drop platform 5 rises provides the thrust of the top drilling of jumbolter 6.
Run into need the long period stop driving when, development machine should be exited, be accomplished manually permanent support.
After the completion of return airway tunnelling, column and knee type gang drill is withdrawn from, sectional shelf-unit can be used as coal-face
Advanced falsework is used.
Only presently preferred embodiments of the present invention is explained in detail above, but the present invention is not limited to above-described embodiment,
In the ken that those of ordinary skill in the art possess, can also be made on the premise of present inventive concept is not departed from each
Change is planted, various change should be included within the scope of the present invention.
