Description
Technical field
The utility model relates to a kind of steel strand anchor pole, belongs to anchor pole ground tackle apparatus field.
Background technology
At present the steel strand anchor pole is often used in supporting under the colliery of China and tunnel shaft; Present steel strand anchor pole adopts steel strand afterbody and the integrally welded design of screw-thread steel more; This design not only needs welding procedure to increase cost; And, make the steel strand anchor pole not reach predetermined strength because high-temperature soldering reduces the intensity of screw-thread steel and steel strand.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of steel strand anchor pole, has characteristics simple in structure, that installation is convenient, intensity is high, technology is easy.
The utility model provides a kind of steel strand anchor pole, comprises steel strand, the body of rod, and the said body of rod comprises extruded sleeve and connecting rod; Extruded sleeve one end has boss, and the boss circumference has external screw thread, and connecting rod one end has shrinkage pool; The shrinkage pool wall has the internal thread that is used with extruded sleeve; Extruded sleeve and connecting rod are through screw fit, and both axis are positioned on the center line, pallet, packing ring, pallet packing ring, packing ring, nut assemble successively with connecting rod on.
Aforesaid steel strand anchor pole; The extruded sleeve other end has extruded hole; The steel strand afterbody is assemblied in extruded hole and through fluid power squeezer extruding integrator, said extruded sleeve cross section is a regular hexagon, and regular hexagon is used for spanner clamping extruded sleeve and tightens and being connected of connecting rod.
The beneficial effect of the utility model is: the utility model does not need complicated welding procedure, has improved production efficiency, has avoided the unstable phenomenon of quality of appearance in the welding, and the intensity of the body of rod is guaranteed.
Description of drawings
Fig. 1 is the utility model embodiment sectional drawing.
Fig. 2 is the utility model A-A sectional view.
The specific embodiment
Embodiment 1
It is a kind of that present embodiment provides, and structure is as shown in Figure 1, comprises steel strand 1, the body of rod; The said body of rod comprises extruded sleeve 3 and connecting rod 2, and extruded sleeve 3 one ends have boss, and the boss circumference has external screw thread; Connecting rod 2 one ends have shrinkage pool; The shrinkage pool inwall has the internal thread that is used with extruded sleeve 3, and extruded sleeve 3 passes through screw fit with connecting rod 2, and both axis are positioned on the center line.
Aforesaid steel strand anchor pole; Extruded sleeve 3 other ends have extruded hole; Steel strand 1 afterbody is assemblied in extruded hole and through fluid power squeezer extruding integrator, said extruded sleeve 3 cross sections are regular hexagon, and regular hexagon is used for spanner clamping extruded sleeve 3 and tightens and being connected of connecting rod 2.
When actual installation is used; Earlier steel strand 1 afterbody is stretched into the extruded hole of extruded sleeve 3 and pushes integrator with the fluid power squeezer; The extruded sleeve 3 that will have steel strand 1 then and connecting rod 2 are fixed through screw thread; The anchor pole insertion that assembles is equipped with in the working hole of anchoring agent, loads onto pallet 4, pallet packing ring 5, packing ring 6 and the nut 7 of screwing at last successively.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
