It is dynamic, in place after, then by the left front upper telescopic mast of preceding branch protecting assembly, it is right before upper telescopic mast 20, left front lower telescopic mast, right front lower flexible
Post 21, which all stretches out, to lengthen, and makes all left front supporting backing boards 3, right anterior branch river bottom protection supporting plate 5 all compress ground, Mei Geqian
Supporting crossbeam 22 all pushes up the top to face before support top beam 13 and preceding spy, it is now whole before branch protecting assembly forward
The distance that the piston rod of oil cylinder 15 forward extends out is moved, in the process, although each preceding support top beam of preceding branch protecting assembly
13 no longer withstand on the top plate of face, but each rear support top beam 14 of rear branch protecting assembly still withstands on getter
Make on the top plate in face, thus achieve the continuous supporting to face top plate, effectively can prevent from being moved along sending out during support
Raw roof fall accident；
Then it is lower telescopic mast behind upper telescopic mast, left back lower telescopic mast and the right side behind the left back upper telescopic mast of rear branch protecting assembly, the right side is complete
Portion is retracted, and makes supporting backing board 10 and left back supporting backing board 8 behind all right sides all leave ground, it is each after the He of support top beam 14
Supporting crossbeam 25 all leaves the top of face after preceding spy, and now whole rear branch protecting assembly all passes through rear supporting longeron 12
Support, by frame on the top of multiple preceding supporting crossbeams 1, then again by the piston rod contraction of multiple oil cylinders 15, supporting after pulling
On component it is corresponding after supporting crossbeam 6, allow it is whole after branch protecting assembly travel forward, in place after, then by the left back of rear branch protecting assembly
Lower telescopic mast all lengthens behind upper telescopic mast, left back lower telescopic mast and the right side behind upper telescopic mast, the right side, makes supporting collet behind all right sides
Plate 10 and left back supporting backing board 8 all compress ground, and supporting crossbeam 25 is pushed up to mining after each rear support top beam 14 and preceding spy
The top of working face, the piston rod that now whole rear branch protecting assembly has moved forward oil cylinder 15 are collapsible into the distance of cylinder body,
In the process, although supporting crossbeam 25 no longer withstands on mining activity after each rear support top beam 14, the preceding spy of rear branch protecting assembly
On the top plate in face, but supporting crossbeam 22 still withstands on getter before each preceding support top beam 13 of preceding branch protecting assembly, preceding spy
Make on the top plate in face, thus achieve the continuous supporting to face top plate, effectively can prevent from being moved along sending out during support
Raw roof fall accident.
It is an object of the invention to provide a kind of new gib equipment and promote a kind of new tunneling construction process.Pass through
The use of support of the present invention, do not improved using only the intensity of gib, and gib operation realizes mechanization and remote
Process control, therefore reached safe and reliable, simple to operate, purpose rapidly and efficiently, realize to top plate continuity supporting.Pass through
The application of the construction skill, separate the cutting operation region of driving machine gun and the supporting operating area of personnel, the place of supporting by
