Abstract
The utility model relates to a colliery anchor rope supporting device specifically is anchor rope tapered end anti -falling device. The utility model provides a lack colliery anchor rope tapered end anti -falling device in the pit at present, leading section problem that the anchor rope tapered end became invalid and falls of actual mining roadway. The utility model discloses a scheme does: anchor rope tapered end anti -falling device, including internal diameter and anchor rope complex sleeve pipe, the sleeve pipe outer wall leaves has the through -hole that has a perfect understanding with the cover internal diameter of pipe, the through -hole oral area is fixed with the nut, it has the screw that has a perfect understanding with the cover internal diameter of pipe to twist in the nut. The utility model has the advantages of it is following: 1, simple structure, low in cost, 2, convenient to use dismantles portably, 3, it is obvious to prevent weighing down the effect, safe and reliable.
Description
Technical field
The utility model is related to colliery anchor cable support apparatus, specially anchor rope lock anti-fall device.
Background technology
In underground coal mine production, cable bolting is that one kind carries out combined supporting using anchor cable and wire netting to coal mine roof plate
A kind of support pattern, because of its relatively conventional supporting for, in terms of bearing capacity, in the supporting of large span section and to emitting
Push up in the supporting in region, be respectively provided with very big superiority, so in China's coal-mine underground with relatively broad.Existing anchor cable branch
It is the upper berth wire netting 7 of top board 6 to protect, and anchor rope supporting plate 8 is then provided with wire netting 7, and the He of anchor rope supporting plate 8 is sequentially passed through with anchor cable 1
Wire netting 7, on the top plate 6, the lower end of anchor cable 1 is screwed with anchor rope lock 9 for anchoring.At present, due to lacking anchor rope lock anti-fall device,
During underground coal mine working face extraction, influenceed by advanced stress, caused crushing for stope drift active workings, so as to cause back
On anchor rope lock often failure falls, to the worker safety of the supporting of stope drift active workings safety and advanced section operation with
Grave danger is carried out.Therefore, in order to eliminate the unsafe factor of the advanced section of support in gateway of coal mining face, it is necessary to design a kind of structure
Simply, convenient anchor rope lock anti-fall device quick for installation, with the defect for overcoming anchor rope lock shielding failure to fall, it is to avoid anchor cable
Tapered end falls the generation of casualty accident.
The content of the invention
The utility model solves to lack underground coal mine anchor rope lock anti-fall device, the advanced section anchor rope lock of stope drift active workings at present
A kind of problem that failure is fallen, there is provided anchor rope lock anti-fall device.
The utility model is achieved through the following technical solutions：Anchor rope lock anti-fall device, including internal diameter is matched somebody with somebody with anchor cable
The sleeve pipe of conjunction, described sleeve pipe outer wall is provided with the through hole with casing inner diameter insertion, and the through hole oral area is fixed with nut, the nut
Inside it is screwed with the screw with casing inner diameter insertion.Casing inner diameter coordinates with anchor cable, sleeve pipe can be placed on into anchor cable lower end.Sleeve outer wall is consolidated
Surely there is nut, screw, screw and casing inner diameter insertion are screwed with nut, tighten screw, head of screw can compress anchor cable lower end, increase
Anti-fall device and the frictional force of anchor cable, fall when preventing the anchor cable head of anchor cable lower end from failing.
Described sleeve pipe outer wall is provided with multiple through holes, and each through hole oral area is respectively and fixedly provided with nut, nut and is screwed with screw.It is many
Be screwed with screw in individual nut, increase the frictional force of head of screw and anchor cable, the adhesive force of the two is increased, can bear bigger top board to
Under pressure.Each through hole is centrosymmetric distribution in the same cross section of sleeve pipe.Each through hole is in same cross section
Central Symmetry is distributed so that head of screw is more preferable to the adhesive force centering of anchor cable, and frictional force is more balanced.The anchor cable head is anti-fall
Device also includes one or more anti-fall iron chains, and one end of the anti-fall iron chains is connected with the wire netting of top board surface, the other end
It is fixedly connected with bushing outer surface.Anti-fall iron chains prevents anchor rope lock and the anti-fall device rear sleeve that fails from falling and injure people from lower section by a crashing object
Member.
The utility model has advantages below：1st, simple structure, it is cheap；2nd, easy to use, dismounting is easy；3rd, it is anti-fall
Effect is substantially, safe and reliable.
Brief description of the drawings
Fig. 1 is the utility model mounting structure schematic diagram；
In figure：1- anchor cables, 2- sleeve pipes, 3- nuts, 4- screws, the anti-fall iron chains of 5-, 6- top boards, 7- wire nettings, 8- anchor cable supports
Plate, 9- anchor rope locks.
Specific embodiment
Anchor rope lock anti-fall device, including the sleeve pipe 2 that internal diameter coordinates with anchor cable 1, the outer wall of described sleeve pipe 2 are provided with and sleeve pipe 2
The through hole of internal diameter insertion, the through hole oral area is fixed with nut 3, the nut 3 screw 4 being screwed with the internal diameter insertion of sleeve pipe 2.
During specific implementation, the outer wall of described sleeve pipe 2 is provided with multiple through holes, and each through hole oral area is respectively and fixedly provided with nut 3, nut 3
Inside it is screwed with screw 4.Each through hole is centrosymmetric distribution in the same cross section of sleeve pipe 2.The anti-fall dress of anchor cable head
Putting also includes one or more anti-fall iron chains 5, and one end of the anti-fall iron chains 5 is connected with the wire netting 7 on the surface of top board 6, another
End is fixedly connected with the outer surface of sleeve pipe 2.
When installing and using, sleeve pipe 2 is put by the lower end of anchor cable 1, the upper end of sleeve pipe 2 is adjacent to anchor rope lock 9, by 4 points of screw
Not by being screwed into the nut 3 of the surrounding of sleeve pipe 2,4 compression anchor cables 1 of screw, so as to increase the frictional force of sleeve pipe 2 and anchor cable 1, are prevented
Anchor rope lock 9 falls after failing.After tightening screw 4, the other end of the anti-fall iron chains 5 that one end is fixed with the outer wall of sleeve pipe 2 is hitched
On wire netting 7, prevent anti-fall device from being fallen after also failing.
