Stretching is supported on ground, and the protection of many weights is provided for the present apparatus, staff's warning function is also given, is provided to staff
Escape space.
3rd, when running into rock burst or when side slope produces large deformation, anchor pole can absorb energy by the deformation of itself,
The deformation of adaptive country rock, the support capacity of effective guarantee anchor pole.To common ground supporting, slope retaining, tunnel rock burst etc.
Burst fire-disaster can play effective buffering and governance role.
Preferred scheme one, as the further optimization to base case, the support column and bottom plate are threaded connection.Support
Post and bottom plate are that threaded connection can be conveniently that hydraulic oil is changed in support column, have ensured the service life of support column.
Preferred scheme two, as the further optimization to preferred scheme one, one end of the support column connection top plate is provided with
With the symmetrical second hydraulically extensible bar of the first hydraulically extensible bar.The present apparatus that is set to of second hydraulically extensible bar provides many weights
Supporting role, be staff safely provide it is many one weight guarantees.
Preferred scheme three, as the further optimization to base case, the quantity of the anchor pole is at least 5.Anchor pole number
Amount at least 5 can be the validity of this suspension device strengthening supporting.
Preferred scheme four, as the further optimization to preferred scheme three, the first hydraulically extensible bar, the second hydraulic pressure are stretched
Contracting bar is corresponding with the quantity of anchor pole.Because the first hydraulically extensible bar and the second hydraulically extensible bar are located at space correspondence between anchor pole
On the support column at place, so quantity is equal, the supporting role of equity is provided for this supporting construction, it is not pressurised generation inclined
Move.
Preferred scheme five, as the further optimization to base case, the reinforcing bar energy-absorbing section is externally provided with outer sleeve, overcoat
Cylinder inwall is provided with screw thread.The setting of outer sleeve can be when anchor pole energy-absorbing section be pulled off, and the inner thread of outer sleeve can connect
Anchor pole reinforcing bar is connect, continues to ensure the validity of suspension roof support by the snap-in force between bush whorl and anchor pole screw thread steel.
