External screw thread.Anchor pole is passed through in flange plate hole, and flanged plate is close to country rock surface, straight at the smooth place of free segment exposed junction with screw thread
Female connector has wedge-shaped intermediate plate, and wedge-shaped intermediate plate periphery is cased with adaptable taper ferrule pad, and taper ferrule pad is arranged on above flanged plate.It is adjacent
Wedge-shaped intermediate plate, metal self-aligning bearing between two endless metal intermediate plates, with hex nut fixed by the thread segment above wedge-shaped intermediate plate
Clamp.
The above-mentioned aligning recoverable anchor rod for increasing anchoring strength, it is characterised in that：The anchoring section processing is corrugated
Shape.
The above-mentioned aligning recoverable anchor rod for increasing anchoring strength, it is characterised in that：The adapter sleeve is welded on freedom
Duan Shang, and be connected by rivet with free segment.
Above-mentioned sees the aligning recoverable anchor rod that can increase anchoring strength, it is characterised in that：The adapter sleeve and anchor pole anchor
Linked Gu section is coincide by screw thread.Adapter sleeve is with free segment junction added with slip casting water fender.
The above-mentioned aligning recoverable anchor rod for increasing anchoring strength, it is characterised in that：The free segment revealed section outermost
It is processed into four prism type in end.
The above-mentioned aligning recoverable anchor rod for increasing anchoring strength, it is characterised in that：The wedge-shaped intermediate plate overcoat has cone
Shape hoop pad.
The above-mentioned aligning recoverable anchor rod for increasing anchoring strength, it is characterised in that：The self-aligning bearing and wedge grip
First annular pad is accompanied between piece, the second annular gasket is accompanied between hex nut.
The utility model has an advantageous effect in that compared with prior art：
1st, the utility model structure is convenient, and installation is simple, and application is strong.Machinery need not be specifically installed.
2nd, the utility model anchoring section is corrugated, big with country rock hole contact area, adds anchoring strength, improves
Anchoring effect.
3rd, the utility model adapter sleeve and the slip casting water fender of free segment threaded connection place, can prevent water from entering adapter sleeve
In bucket, so prevent from the threaded connection place of adapter sleeve and free segment due to water effect and corrosion, by increasing capacitance it is possible to increase this can be returned
The service life of half davit, while can also prevent from reclaiming difficulty caused by corrosion.
4th, the pulling force of prestressed anchor can be changed into the extruding force of wedge-shaped intermediate plate by the utility model, so as to clamp anchor pole
Free segment, external force holds more greatly more firm.
5th, the utility model is by setting self-aligning bearing, the recoverable anchor rod can be prevented with country rock face out of plumb or
To the damage of anchor pole when in installation process due to eccentric force, the recoverable anchor rod stress equalization can be made, make anchor pole more preferable
Play anchorage effect.
In summary, the utility model is simple in construction, easy for installation, and anchoring effect is good, and recovery is convenient, service life length,
Production cost is greatly reduced, economic technology is profitable, and application value is high.
