Abstract
The invention discloses a device and a method for withdrawing a striking type anchor cable provided with anchor withdrawing rings. The device comprises a lock and a tray both sleeving the exposed section of the anchor cable; anchor withdrawing rings combined in pairs are arranged between the lock and the tray and are the same in structure; a plurality of lugs are arranged at the outer edges of the anchor withdrawing rings; a plurality of grooves are formed in the opposite ends of the anchor withdrawing rings and can be engaged into each other. When the anchor cable is mounted, the lugs at the outer edges of the paired anchor withdrawing rings are aligned to each other and mounted between the lock and the tray; before withdrawing, the lugs of one anchor withdrawing ring are knocked so that two anchor ring in a pair can be staggered and engaged with each other and the concavo-convex connection of the two anchor withdrawing rings can be realized; as a result, an axial compensation space for the axial motion of the lock can be provided, the anchor cable can be loosened, and consequently, the purpose of efficiently and safely withdrawing the anchor can be achieved. The anchor withdrawing process is greatly improved; the labor intensity of a worker can be reduced; the safety of the anchor withdrawing work is increased; the device is simple in structure, low in cost and easy to popularize.
Description
Technical field
Patent of the present invention is that a kind of prepackage is moved back the knocking anchor cable of anchor ring and moved back anchor device and method, is particularly suited for tunnel
Move back anchor operation.
Background technology
Push ahead with coal-face, the anchorage cable anchoring power of two lane goaf side top boards does not release, and easily causes work
Make face termination larger area and hang top, aggravation termination stress raisers, cause termination methane accumulation simultaneously, be roof control with watt
This improvement brings potential safety hazard.Therefore, for timely caving, reduce control top area, solve the problems, such as termination gas, coal mining activity simultaneously
During often carry out moving back anchor operation.
Mainly anchor is moved back using stretch-draw anchor mode at present.But during initial stage construction anchor cable, control country rock to become by high pretightening force
Shape, significantly reduces the extending length of anchor cable；And later stage tunnel be subject to mining influence large deformation when, particularly superficial loosely crushes
Tunnel, a batch of anchorages are absorbed in inside country rock.Tensioning is significantly greatly increased and moves back anchor difficulty, cause to move back that anchor effect is poor, efficiency is low, anchor
Rope decortication takes place frequently, and moves back anchor process simultaneously and stretches the meaning, there is roof fall risk.Therefore need a kind of novel disk withdrawal anchor device of proposition and side badly
Method, solves an above-mentioned difficult problem.
Content of the invention
Technical problem: the purpose of the present invention is to overcome the shortcomings of to use anchor restorer operation at present, provides a kind of prepackage to move back anchor
The anchor cable of ring moves back anchor device and method, moves back anchor ring, thus reaching highly effective and safe to move back anchor by pair-wise combination.
Technical scheme: the knocking anchor cable that anchor ring is moved back in the prepackage of the present invention moves back anchor device, including being set on anchor cable revealed section
On lockset and pallet, be provided with the anchor ring that moves back of pair-wise combination between described lockset and pallet, described pair-wise combination move back anchor ring
Structure is identical, and outer rim is provided with multiple lugs, and opposite side is all machined with the multiple grooves that can be mutually entrenched togather.
The described anchor ring height that moves back is 30～40mm；The lug moving back in anchor ring outer rim is 2～5, uniformly arranges；Relatively one
The groove that end can mutually be entrenched togather is 2～5, and depth of groove is 8～20mm.
Described move back anchor ring internal diameter than anchor cable diameter big 5～10mm, external diameter big 5～30mm than lockset diameter.
Move back anchor method using the knocking anchor cable that anchor ring is moved back in the prepackage of said apparatus, comprise the steps:
When a, construction anchor cable, moved back the lug alignment of anchor ring outer rim in pairs, be arranged between lockset and pallet, other operations
Identical with anchor cable installation procedure；
B, move back anchor operation before, tap and move back anchor ring in pairs one of them moves back anchor ring outer rim lug, make the pair of two and move back anchor
Ring dislocation is chimeric, in concavo-convex connection shape so that anchor cable relaxes；
C, when moving back anchor operation, it is locked anchor cable using moving back anchor clamping device, by moving back the chimeric nose balance providing of anchor ring dislocation
Space, conveniently moves back anchor clamping device jack-up lockset overcoat, thus conveniently taking off lockset, moving back anchor ring and pallet, completes to move back anchor operation.
Beneficial effect: due to employing technique scheme, the present invention compared with prior art has the advantage that
1st, tap and move back anchor ring outer projection, make to move back the anchor ring changing of the relative positions and be fitted together to, provide an axle for anchor restorer jack-up lockset overcoat
To compensation space, make the easy operation of anchor restorer, significantly improve and move back anchor effect and efficiency；
2nd, during moving back anchor, all parts are not damaged substantially, the reuse of the part such as achievable lockset, effectively save
Cost；
3rd, move back anchor ring big compared with lockset diameter, reduce the stress concentration to pallet for the lockset, improve the force environment of pallet；
4th, present configuration is simply exquisite, convenient operation, significantly reduces labour intensity, reduces the danger moving back anchor operation
Dangerous coefficient is it is easy to promote.

Specific embodiment
Below in conjunction with the accompanying drawings one embodiment of the present of invention is further described:
The knocking anchor cable that anchor ring is moved back in the prepackage of the present invention moves back anchor device, mainly by being set on moving back on anchor cable 2 revealed section
Anchor ring 1, lockset 3 and pallet 4 are constituted, and anchor cable 2 stretches in top board, and pallet 4 acts against on top board.Described moves back paired group of anchor ring 1
Close, the anchor ring 1 that moves back of pair-wise combination is located between lockset 3 and pallet 4, pair-wise combination move back that anchor ring 1 structure is identical, outer rim is provided with
Multiple lugs, opposite side is all machined with the multiple grooves that can be mutually entrenched togather.Moving back anchor ring height is 30～40mm；Move back anchor
Lug in ring 1 outer rim is 2～5, uniformly arranges；The groove that opposite side can mutually be entrenched togather is 2～5, groove
