On.
The cherry coal tunnels U-shaped canopy mechanization installation shield ejection device in use, first, according to said structure connected mode,
It is good that cherry coal driving face will protect ejection device mounting arrangements；It is that support post 14 stretches out to give tacit consent to original state, moves frame hydraulic cylinder
15th, outrigger hydraulic cylinder 23 and passage hydraulic cylinder 18 are withdrawn.Then, using development machine or drive hoeing machine, in supporting support body main frame
In the safety work space 17 formed with auxiliary case frame, the excavation operation of soft coal opening is carried out.With the vertical of embedded Hu Ding mechanisms 11
Plate is the plane of reference, is shut down after tunneling 600~700mm forward, and U-shaped canopy 9 and top anchor net 10 are placed on to the arc of installation outrigger 8
Lift in neck 22, and protection network 12 and protecting wire net hydraulic cylinder 13 can be installed according to specific gear cash needs；Afterwards, stretching is chosen
Beam hydraulic cylinder 23, and then drive and rotate U-shaped canopy 9 and top anchor that swing arm 21 drives arc to lift neck 22 and arrange thereon
Net 10 swings upwards into installation station, then fixes the U-shaped side leg of canopy two and anchor net, and then in the protection of embedded Hu Ding mechanisms 11
Under, realize U-shaped canopy 9 and anchor net 10 mechanization installation；Lift operating efficiency.
When shield ejection device needs to move forward with the excavation operation of soft coal opening, need first by protection network 12 and network protecting liquid
Cylinder pressure 13 is pulled down；Stretch out the passage hydraulic cylinder 18 of the auxiliary front end of beam 2 of auxiliary case frame again, come promote whole embedded Hu Ding mechanisms 11 to
Preceding movement, and then supporting is carried out to cherry coal top plate exposed in front of supporting support body.Then, fall（Withdraw）Supporting support body main frame
Main front beam 3 and the both ends of main rear cross beam 7 support post 14, the main beam I 4 and main beam II 5 and tunnel for making main frame push up
Plate is temporarily disengaged from out；Afterwards, stretch out and move frame hydraulic cylinder 15, promote the main frame reach for having dropped frame.Before the main frame of supporting support body
After moving on to position, rise again（Stretch out）The main front beam 3 of main frame and the support post 14 at the both ends of main rear cross beam 7, allow main frame
Main beam I 4 and main beam II 5 support back.Then, then the auxiliary front beam 1 of supporting support body auxiliary case frame and auxiliary is fallen
The support post 14 at the both ends of rear cross beam 6, the auxiliary beam 2 of auxiliary case frame is separated from back, and withdraw and move frame hydraulic cylinder 15,
And then pull the auxiliary case frame reach for having dropped frame.After the auxiliary case frame reach in place of supporting support body, the support post 14 of auxiliary case frame is risen.
Repeat the operation of above-mentioned driving, the U-shaped canopy of mechanization installation and anchor net, reach supporting support body and embedded Hu Ding mechanisms
Circulation, alternately lifted by this main frame of supporting support body and auxiliary case frame, the form of reach, ensure the moving process in device
In, there is a framing to be in all the time and connect dome-shaped state, and advance support in working region top, is realized all the time for embedded Hu Ding mechanisms
Continuous-stable supporting to cherry coal Roadway Roof, it is ensured that the security of cherry coal driving face operation.
