Description
Technical field
The present invention relates to underground coal mine supporting lockset, the anti-anchor cable lock that breaks of specially a kind of mining aligning-type Self-unlocking
Tool.
Background technique
Currently, underground coal mine adopts tunnel uses combined support with bolt-net-cable mode mostly, cable bolting structure is by anchor cable, support
Plate, aligning ball pad and lockset composition.In work progress, the good anchor cable of anchor cable insertion top board construction is drilled first, it is hole to be drilled in
After Anchor Agent anchoring, it is successively inserted in supporting plate, aligning ball pad and anchor cable lock in anchor cable, then uses anchorage cable stretching machine tensioning anchor
Rope makes anchor cable generate certain flexible deformation and pretightning force, after tensioning, by carving among the elastical retraction and lockset of anchor cable
The self-locking function of shape lock core locks anchor cable, to have the function that cable bolting.
Lockset in cable bolting structure is made of outer lock body and internal lock core.Outer lock body is cylindrical, and inside is opened
If round platform hole；Internal lock core is made of three wedge locking plates, and dentation is processed into inside lock core, facilitates gripping by anchor cable.The lockset
Structure design can not achieve unlocking function, and with the increase of mining depth, roadway surrounding rock stress is with increase, anchor cable end
Portion's fracture collapses appearance as bringing very big security risk to Safety of Coal Mine Production in increasing trend year by year, the lockset also without
The function that anti-anchor cable breaks.
Lockset itself is without aligning function simultaneously, and aligning ball pad need to be cooperated using being just able to achieve aligning function.
Anchor wire withdrawing device is made of oil pump (manually, Pneumatic oil pump), high-pressure oil pipe assembly, anchor cable drawbench.
With the increase of mining depth, surrouding rock stress increases, and anchor cable stress increases with it, and stretcher strain is serious, due to mesh
Preceding situation is casted anchor, and to provide pulling force limited for rope anchor restorer, and anchor cable have stretching space enough, and it is very difficult to cause to move back anchor, with
After oil pressure constantly increases in anchor restorer, it is also possible to cause pipeline rupture, anchor cable to break the security risks such as hurt sb.'s feelings；
With the application of high-intensitive anchor cable, cause anchor wire withdrawing device to move back anchor watch and add difficulty, while also increasing under high-stress state
The security risk of personnel's construction；
In process of production, many anchor cable ends are serious by destructions such as advanced section bracket, development machine, transportation systems, so that anchor cable
Anchor restorer can not clamp anchor cable, cause that anchor can not be moved back, and so as to cause anchor wire withdrawing device reliability decrease, it is slower to move back anchor speed,
It is inefficient to move back anchor.
Summary of the invention
The present invention in order to solve existing lockset exist can not Self-unlocking, the protection that breaks without anti-anchor cable, Self-aligning and can not adopt
The time-consuming and laborious problem of anchor is moved back with anchor restorer, provides a kind of anti-anchor cable lock that breaks of mining aligning-type Self-unlocking.
The present invention is achieved by the following technical scheme: a kind of anti-anchor cable lock that breaks of mining aligning-type Self-unlocking,
Lock core including sleeve and position in the inner, sleeve are provided with made of the hexagonal prisms of through-hole center, are provided on the downside of sleeve
Portion's diameter is less than the ladder-like pedestal of lower diameter, and the center of ladder-like pedestal is provided with anchor cable hole, ladder-like pedestal lower end surface
Outer edge is aligning cambered surface, and the top of ladder-like pedestal is located in sleeve, and is cooperated with bush whorl, ladder-like pedestal upper surface
The sleeve lining of upside is the cone structure that upper diameter is less than lower diameter；Be cased on the outside of lock core cooperate with its lateral wall and with
The lock core groove of medial wall of the tube cooperation is covered, lock core groove is made of two block-shaped identical lock core groove ontologies；Sleeve bottom end and rank
It is provided with anti-fall ring pads between the cascaded surface of scalariform pedestal, and the opposite side of anti-fall ring pads is provided with and hangs with its one
Ear.
When operation, the good anchor cable of anchor cable insertion top board construction is drilled, after middle Anchor Agent solidification hole to be drilled, successively set is started going to a nursery
Plate and lockset carry out anchorage cable stretching, fixation, complete anchor cable installment work；One end of subsequent wirerope is connect with hanging ring, wirerope
The other end connect with tunnel surface metal net, prevent the fracture of anchor cable end from flying out and hurt sb.'s feelings；When moving back anchor, set is twisted using spanner
Cylinder, until sleeve back-outs, after sleeve is back-outed, lock core groove separation, anchor cable lock without bearing capacity, withdraw at this time lockset and
Anchor work is moved back in anchor cable pallet, completion；After last lockset and anchor rope supporting plate recycling, depending on lockset and supporting plate corrosion and situation is destroyed, choosing
Can be reused after selecting and examining, overcome existing lockset exist can not Self-unlocking, the protection that breaks without anti-anchor cable, not can oneself
Aligning and the time-consuming and laborious problem of anchor is moved back using anchor restorer.
The angle of sleeve lining and vertical direction on the upside of ladder-like pedestal upper surface is 1 degree.
Upper cartridge is main force part, and the angle of 1 degree of setting ensure that the thickness of upper sleeve wall well, sufficiently
The effect for having played material guarantees the intensity of lockset, and in anchor cable work, is primarily subjected to the horizontal direction transmitted by lock core
Power, manually sleeve can both be backed out from lockset using spanner, if anchor cable end is destroyed and (rushes open flower), sleeve can also be with
It is slowly pulled out along anchor cable.
The internal diameter of lock core groove lower end and the internal diameter of anchor cable hole are identical.
Structure of the invention design rationally it is reliable, compensate for anchor cable lock can not Self-unlocking defect, pass through spanner realize solution
It locks, move back anchor function, eliminate anchor wire withdrawing device, and realize aligning function, reduce component processing and execute-in-place process, together
When prevent the fracture of anchor cable end to fly out the generation of phenomenon of hurting sb.'s feelings, ensured under conditions of guaranteeing lockset bearing capacity and moved back anchor
Reliability and ease for operation substantially increase anchor cable and move back anchor efficiency and move back anchor success rate, and thoroughly having prevented anchor cable end can not pass
Enter anchor wire withdrawing device and leads to not the generation for moving back anchor phenomenon.
