This utility model offer techniques below scheme:
A kind of flexible roof bolt, it is characterised in that: it includes steel strand wires, is arranged with sleeve pipe on steel strand wires, on sleeve pipe also
It is provided with the nut of corresponding matching, the steel strand wires of sleeve pipe side are equipped with pallet, the steel wire rope of pallet side is additionally provided with
The latch of one, the circle centre position at described latch is provided with the cross section corresponding matching plum blossom-shaped through hole of and steel strand wires.
On the basis of above-mentioned art scheme, it is also possible to have a technical scheme further below:
Described latch is rectangle, and is additionally provided with the pin of and latch end face corresponding matching on pallet.
Being provided with a circular arch protruding to side on pallet, it is logical that the circle centre position of circular arch is provided with sleeve pipe corresponding matching
Hole.
Described nut is spherical crown regulation of mental activities nut, and spherical crown one end of described spherical crown regulation of mental activities nut and pallet opposite side table
Face is corresponding.
The beneficial effects of the utility model:
This utility model is compared with common bolt, flexible roof bolt, and installation is convenient, and lever strength high-bearing capacity is big,
During fastening nut, the body of rod does not rotates, can reach design torsional forces requirement, exposed junction reliable lock, non-slip, occur without spark
And protruded length is little, do not affect the effective depth in tunnel.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of this utility model embodiment 1；
Fig. 2 is the structural representation of latch 4 in this utility model；
Fig. 3 is the structural representation of this utility model embodiment 2.
Detailed description of the invention:
Embodiment 1:
As shown in Figure 1, 2, a kind of flexible roof bolt, it is characterised in that: it includes steel strand wires 1, coordinates in figure on steel strand wires 1
Sleeve pipe 2 is fixed on steel strand wires 1 by the method that not shown Extruding spring hydraulic pressure press-fits.Described Extruding spring is triangular shape
The helical spring of cross section.
The outer wall of sleeve pipe 2 is provided with screw thread 2b, sleeve pipe 2 is arranged with the spherical crown regulation of mental activities nut with screw thread corresponding matching
2a, it is possible to use plain nut adds the combination of spherical washer to replace spherical crown regulation of mental activities nut 2a.
Arranging one and be provided with a circular arch 3b raised up on pallet 3 at pallet 3, the circle centre position at circular arch 3b sets
Have and the through hole of sleeve pipe 2 corresponding matching, pallet 3 lower surface is the most vertically provided with the pin 3a of a column.
Described pallet 3 is located on the steel strand wires 1 of spherical crown regulation of mental activities nut 2a spherical crown side so that spherical crown regulation of mental activities nut
2a spherical crown top forms corresponding matching with the top of the circular arch 3b of pallet 3.
Arranging a rectangle latch 4, the circle centre position at described latch 4 is provided with the cross section pair of and steel strand wires 1
Plum blossom-shaped through hole 4a should be coordinated.
Described latch 4 is located on the steel strand wires 1 of pallet 3 lower surface side so that latch 4 one side surface and torr
Dish 3 lower surface fits, and described latch 4 thickness end face forms spacing cooperation with the wherein one side on pin 3a.
Work process:
The diameter of flexible roof bolt, the length made according to steel strand wires 1 first get out corresponding armature boring with jumbolter,
Anchor Agent puts into boring, and with flexible roof bolt anchored end jacking foot of hole, then with top tool, rig is connected with anchor pole afterbody
Get up, start jumbolter stirring Anchor Agent, and allow rectangle latch 4 be close to crag, after Anchor Agent reaches setting time,
Again the pin 3a on pallet 3 is stuck on the side thickness end face of rectangle latch 4, rectangle latch 4 is carried out spacing, then
Spherical crown regulation of mental activities nut 2a is rotated so that spherical crown top is pushed against the top of the circular arch 3b of pallet 3 by instrument.
At this moment, owing to rectangle latch 4 is close on crag, again latch 4 is squeezed by fastening nut pallet 3
Pressure, so adding again the frictional resistance with scar, adding the pin 3a on pallet 3 and stopping that latch 4 rotates, so further
Rear latch 4 by the plum blossom-shaped through hole being enclosed within steel strand wires 1, prevents again the flexible roof bolt body of rod be made up of steel strand wires 1
Reversing, the most do not affect body of rod stress and freely stretch, such nut just can be tightened on request and reach design torque power.
Embodiment 2:
As shown in Figure 2,3, a kind of flexible roof bolt, it is characterised in that: it includes steel strand wires 1, coordinates in figure on steel strand wires 1
Sleeve pipe 2 is fixed on steel strand wires 1 by the method that not shown Extruding spring hydraulic pressure press-fits.Described Extruding spring is triangular shape
The helical spring of cross section.
The outer wall of sleeve pipe 2 is provided with screw thread 2b, sleeve pipe 2 is arranged with the spherical crown regulation of mental activities nut with screw thread corresponding matching
2a, it is possible to use plain nut adds the combination of spherical washer to replace spherical crown regulation of mental activities nut 2a.
Arranging one and be provided with a circular arch 3b raised up on pallet 3 at pallet 3, the circle centre position at circular arch 3b sets
Have and the through hole of sleeve pipe 2 corresponding matching.
Described pallet 3 is located on the steel strand wires 1 of spherical crown regulation of mental activities nut 2a spherical crown side so that spherical crown regulation of mental activities nut
2a spherical crown top forms corresponding matching with the top of the circular arch 3b of pallet 3.
Arranging a rectangle latch 4, the circle centre position at described latch 4 is provided with the cross section pair of and steel strand wires 1
