Description
Technical field
The present invention relates to coal mine lockset, specially a kind of coal mine is with self solving locking-type anchor cable lock.
Background technology
Currently, the supporting of the fully-mechanized mining working stope drift active workings of whole nation major part coal mine has been all made of combined support with bolt-net-cable side
Formula, in practice it has proved that, combined support with bolt-net-cable has good supporting effect, to keeping stope drift active workings section, simplifying coal work
Face end process, to adopt face per unit area yield extremely advantageous for raising.
Coal mine is mainly made of anchor cable, supporting plate, lockset and aligning ball pad using cable bolting structure.It is first in work progress
Anchor cable is first inserted into the good anchor cable of top board construction to drill, after middle Anchor Agent anchoring hole to be drilled, supporting plate is inserted in anchor cable successively, adjusts
Bulbus cordis pad and anchor cable lock.Then anchorage cable stretching machine stretch-draw anchor is used, anchor cable is made to generate certain flexible deformation and pretightning force,
After tensioning, anchor cable is locked by the self-locking function of wedge lock core among the elastical retraction and lockset of anchor cable, to reach anchor
The effect of rope supporting.
Anchor cable lock is made of outer lock body and internal lock core.Lock body is cylindrical, and inside opens up round platform hole.Lock core is by three
A wedge locking plate forms, and is processed into dentation inside lock core, is conducive to step up anchor cable.The lockset only has locking function, can not achieve
Unlocking function.
When carrying out moving back anchor processing to anchor cable, mine moves back anchor device and mostly uses anchor wire withdrawing device greatly at present, and anchor restorer is by oil pump
（Optional electronic, Pneumatic oil pump）, high-pressure oil pipe assembly, anchor cable drawbench composition.Anchor cable drawbench can clamp anchor cable, pass through height
Stretching force pulls out anchor cable, manually removes lock core, to realize the function of moving back anchor.But the mine larger in roadway surrounding rock stress,
Anchor cable stress increases therewith, and stretcher strain is serious, and since anchor wire withdrawing device offer pulling force is limited under present circumstances, and anchor cable is
Through not stretching space enough, it is very difficult to cause to move back anchor, after oil pressure constantly increases in anchor restorer, it is also possible to cause oil
Tracheal rupture, anchor cable break the security risks such as hurt sb.'s feelings.In particular with the application of high intensity anchor cable, anchor wire withdrawing device is caused to move back anchor watch
Add difficulty.In plus production process, many anchor cable ends are serious by destructions such as advanced section holder, development machine, transportation systems, make
Anchor cable can not be clamped by obtaining anchor wire withdrawing device, cause that anchor can not be moved back.So as to cause anchor wire withdrawing device reliability decrease, anchor speed is moved back
It is relatively slow, it is inefficient to move back anchor.
Invention content
The present invention is in order to solve larger and inefficiency there are time-consuming and laborious, security risk when existing anchor cable moves back anchor ask
Topic provides a kind of coal mine with self solving locking-type anchor cable lock.
The present invention adopts the following technical scheme that realization：A kind of coal mine is with self solving locking-type anchor cable lock, including sleeve-shaped
The lateral wall of lock body and lock core, sleeve-shaped lock body is provided with holding tank, and sleeve-shaped lock body bottom inside wall is provided with lower diameter and is more than
The ladder mouth of upper diameter, and sleeve-shaped lock body bottom end is provided with the ladder-like pedestal for coordinating and being threadedly coupled with ladder mouth, rank
The center of scalariform pedestal is provided with anchor cable impenetrating mouth, and several anti-skid studs are provided on the bottom face of ladder-like pedestal, sleeve-shaped lock
Body upper inner wall be upside diameter be less than downside diameter circular conical surface, and be provided in sleeve-shaped lock body top be close to it and
The sleeve-shaped snap ring being close to lock core, the inner wall of sleeve-shaped snap ring are more than the circular conical surface of downside diameter, and sleeve for upside diameter
Shape snap ring is made of two semicircle shape snap ring ontologies.
When operation, anchor cable is inserted into the good anchor cable of top board construction and is drilled, after middle Anchor Agent anchoring hole to be drilled, set is started going to a nursery successively
Plate, aligning ball pad and lockset carry out anchorage cable stretching, fixation, complete anchor cable installment work, under anchor cable working condition, vertical direction
Stress is transferred mainly to ladder-like pedestal so that anti-skid stud is in close contact with anchor rope supporting plate or supporting plate upper centring ball pad；When moving back anchor,
Lockset holding tank is blocked using spanner, under the friction force effect of anti-skid stud, sleeve-shaped lock body is back-outed, the separation of sleeve-shaped snap ring
For two halves, anchor cable lock without bearing capacity, withdraw at this time sleeve-shaped card slot, ladder-like pedestal, lock core, aligning ball pad and
Anchor cable pallet, the corrosion depending on anchor cable lock and anchor rope supporting plate and destruction situation, select and are reused after examining, overcome
Existing anchor cable has that time-consuming and laborious, security risk is larger and inefficiency when moving back anchor.
Sleeve-shaped lock body upper inner wall and the angle of its vertical direction are 1 °.
The structure design further ensures the stabilization of stress under the premise of ensureing that sleeve-shaped snap ring will not move axially
Performance.
Structure of the invention reasonable design is reliable, in the case of the external professionals equipment such as no anchor wire withdrawing device, passes through well
Lower ejector lever realizes the unlock of anchor cable lock, moves back anchor function, and substantially increases moving back for anchor cable and anchor efficiency and move back anchor success rate,
And then stope working surface of coal mines end top plate is made across falling, to reduce face end surrouding rock stress and working face up and down corners in time
Gas accumulation area area improves face end top-coal recovery rate, promotes safety of coal mines high-efficiency mining, while wanting to field condition
Ask relatively low, anchor cable end miscued, hit dissipate in the case of still can normally move back anchor, protected under conditions of ensureing lockset bearing capacity
Barrier moves back the reliability and ease for operation of anchor.
