The concrete scheme that the utility model is solved the above problems is:The aligning recoverable anchor rod of anchoring strength can be increased, It is characterized in that:This anchor pole is made up of anchoring section and free segment.Anchoring section is connected with free segment by adapter sleeve.Adapter sleeve welds , also by rivet interlacement, add adapter sleeve with free segment close to the side of anchoring section, adapter sleeve in free segment and connect with free segment The stability connect, for the not strong technology short slab of nowadays recoverable anchor rod anchoring strength, the utility model processes anchoring section It is corrugated, the contact area of increase anchoring section and country rock hole, so as to reach the purpose of increase anchoring strength.And anchoring section leans on The side of nearly free segment is machined with external screw thread, and adapter sleeve is machined with the internal thread to match, adapter sleeve close to the side of anchoring section It is connected through a screw thread with anchoring section.Slip casting water fender is also lined with anchoring section and adapter sleeve junction, in order to avoid anchoring section and connection The threaded connection place of set is difficult to dismantle because of corrosion, influences anchor recovering.The exposed junction of free segment, it is machined with away from country rock one end 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.

Embodiment
As shown in figure 1, the utility model includes anchoring section 1, free segment 2, adapter sleeve 3, rivet 4, slip casting water fender 5, method Blue plate 6, taper ferrule pad 7, taperliner 8, endless metal pad 9,11, self-aligning bearing 10, hex nut 12.The anchoring section 1 For corrugated, anchoring section 1 is connected with free segment 2 by adapter sleeve 3, and the external screw thread of the internal thread and anchoring section 1 of adapter sleeve 3 is mutual It coincide.Adapter sleeve 3 is welded on free segment 2, and adapter sleeve 3 is also connected with free segment 2 by rivet 4 in addition.Slip casting water fender 5 is set In the threaded connection place of adapter sleeve and free segment.Free segment exposed junction, the periphery of taperliner 8 are cased with taper ferrule pad 7, padded together On flanged plate 6.Self-aligning bearing 10 is accompanied between two endless metal pads 9,11, and is fastened by self-aligning bearing.
As shown in Fig. 2 there are taper ferrule pad 7 and taperliner 8. on flanged plate 6
As shown in figure 3, hex nut 12 is threaded onto on free segment 2 by coincideing, and wedge-shaped intermediate plate 8 is fastened. The outermost one end of free segment exposed junction is arranged to four prism type.
When this utility model is installed, punched by roof bolting machine on the lateral wall of tunnel, be put into Anchor Agent;Free segment is worn Flange plate hole is crossed, is linked together through adapter sleeve and anchoring section;Body of rod stirring powder stick is rotated, powder stick is solidified, fastens hexagonal spiral shell Mother, flanged plate is set to be close to help wall.And by self-aligning bearing, make anchor pole from the exposed junction of free segment to the anchoring in country rock hole Section center line keep point-blank, reach anchor pole will not fatigue use and cause it is anchor rod anchored effect failure purpose.And The fastening force of hex nut is acted on wedge-shaped intermediate plate, is conducted fastening force to anchoring section by taper ferrule pad, is made anchor pole more preferable Performance anchorage effect.
During this utility model disassembly & recycling, hex nut is unclamped, remove in order endless metal pad, taperliner, Taper ferrule pad and flanged plate.An exposed junction outermost part for free segment is processed as quadrangular present situation, is easy to anchoring-rod dismounting to reclaim. Anchor pole is rotated, adapter sleeve is separated with anchoring section, so as to reach the purpose of recovery free segment.
