By and be easy to workmen pass through.
The support bar is square-tube-shaped steel.It is easy to selection, it is cheap.
Lay the reinforced mesh of supporting in the top of support frame as described above.Before supporting operation, reinforced mesh is routed to into support
Frame top, bracing frame is risen to after top plate contact, and operating personnel can the safety work under the temporary support device.
The both sides of the supporting platform are provided with for the upper and lower staircase of personnel.It is easy to the upper and lower operation platform of personnel.
The supporting platform is grid type pedal.It is not only convenient for installing, changes, can also well plays anti-skidding effect.
The hydraulic jack of the present invention is mainly used in controlling the rising and dropping control of bracing frame.Support post is combined into hydraulic jack
One toggle, is equally used for the rising and dropping control of temporary support, while weight and the top for undertaking bracing frame
Plate pressure.
The present invention has compared to existing technology advantages below：When the present invention solves mining TBM supportings, the erect-position of personnel,
Gib and mesh sheet lift problem, not only can to the temporary support of back, while can be used for lifting mesh sheet, and
Using hydraulic control, relative to traditional full-mechanized roadway gib, safety is higher, and labor intensity of operating staff is low, operation
Simply, it is easy to operate, it is very useful at the scene.
