Abstract
The utility model relates to an anchor rope that anchor ring was moved back to crisscross knot formula mutually of pre -installation moves back anchor device, two a set of, two crisscross knot styles mutually of when used are moved back anchor ring and are spliced into one hollow cylinder, install between tool to lock and tray, when moving back the anchor, strike the convex body that one side of anchor ring was moved back to crisscross knot formula mutually with the hammer, form the compensating space that a segment supplied tool to lock axial motion between tool to lock and tray, move back the anchor with the completion, simplification that this device is very big move back anchor operation construction process, the hand -operated cutter assembling body is also advantaged by reducing labor intensity of workers, the security of moving back the anchor operation has improved, and processing technology and application method are simple, the part can repeat repetitious usage, investment cost has been saved, and easy popularization.
Description
Technical field
This utility model patent is a kind of to pre-install the anchor cable that staggered phase button moves back anchor ring and move back anchor device, moves back anchor operation for realizing the safety of anchor cable at underground coal mine.
Background technology
Anchor pole rope supporting has low cost, supporting effect is good, easy and simple to handle, use flexibly, take the advantages such as construction headroom is few; it it is most popular a kind of support pattern in China's coal-mine; but in actual application; owing to the anchorage cable anchoring power of face end top board does not release; often can cause the outstanding top of face end rear larger area; easily cause methane accumulation, thus bring great challenge to roof control and gas control.Therefore, China's coal-mine many employings anchor restorer moves back the method for anchor and solves this problem making goaf top plate be caving, but this method easily causes fall of ground, there is great danger, therefore back anchor cable moves back anchor problem is the problem needing solution in Safety of Coal Mine Production badly.
Summary of the invention
Technical problem: this utility model is the drawback solving to use the tradition such as anchor restorer to move back anchor instrument, to reach to move back safely the purpose of anchor operation.
Technical scheme: this utility model is a kind of to be pre-installed the staggered phase button that the anchor cable that staggered phase button moves back anchor ring moves back used by anchor device and move back anchor ring, two one group, with the use of, during use two interlock phase button move back about anchor ring splice, be installed between lockset and pallet, when moving back anchor, tap, with hammer, the convex shape that staggered phase button moves back the side of anchor ring, make two to move back anchor ring and open and drop, the most just provide a compensation space for lockset axially-movable, such that it is able to take off lockset, to complete to move back anchor.
Its technology path is as follows:
A, on ground, the staggered phase button of preparation moves back anchor ring, its material is ferrum or rigid plastics, after two staggered phase buttons move back anchor ring alignment installation, form hollow circular cylinder, its internal diameter is big 1 ~ 5mm than anchor cable diameter, external diameter 0-10mm bigger than anchor ring diameter, highly 3-40mm, staggered phase button moves back convex shape on anchor ring side, all vertical hollow cylindrical shafts to plane all produce anti-slip veins；
B, work surface two crossheading tunnel during install anchor cable time, two staggered phase buttons move back anchor ring fastening, be installed between pallet and anchor cable lock, other operations are identical with anchor cable installation procedure；
C, in work exploitation process, when needing to move back anchor, tap staggered phase button with hammer and move back the convex shape of anchor ring, make to move back anchor ring and drop between lockset and pallet, the most just provide a compensation space for lockset axially-movable, such that it is able to take off lockset, it is achieved move back anchor.
Beneficial effect:
1, simple in construction, processing technique is simple, can realize anchor cable lock and the recycling of anchor restorer tool, significantly reduce cost；
2, easy to use, reduce the requirement of the operation level to workman；
3, increase and move back anchor operational security.
Accompanying drawing explanation
Fig. 1 is to install staggered phase button to move back the anchor cable profile of anchor ring, and Fig. 2, Fig. 3 are side views of the present utility model；
1-anchor cable in Fig. 1,2-top board, 3-pallet, the 4-phase button that interlocks moves back anchor ring, 5-anchor cable lock, 6-convex shape；In Fig. 2, a, b, c are three parts that staggered phase button moves back anchor ring parts.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is further described:
As shown in Figure 1, Figure 2, Figure 3 shows, this utility model is a kind of pre-installs the anchor cable that staggered phase button moves back anchor ring to move back anchor device detailed description of the invention as follows:
1, anchor ring is moved back at the staggered phase button of ground preparation, staggered phase button moves back anchor ring by a, b, c tri-part composition, 1/4 hollow cylinder that b is cut out by hollow cylinder axle center and mutually perpendicular two planes, a with c is identical, be by be perpendicular to plane axial for b along b height half be cut into, connected mode between three parts is welding or one piece casting, there is convex shape (6) in the outside of b, all vertical hollow cylindrical shafts to plane all produce anti-slip veins, it is ferrum or ferroalloy that staggered phase button moves back anchor ring (4) material, after two staggered phase buttons move back anchor ring (4) alignment installation, the hollow circular cylinder with two convex shapes (6) can be formed, its internal diameter is than the big 1 ~ 5mm of anchor cable (1) diameter, external diameter is than the big 0-10mm of anchor cable lock (5) diameter, highly 3-40mm；
When 2, installing anchor cable during work surface two crossheading tunnels, two staggered phase buttons being moved back anchor ring (4) and buckles, form a hollow cylinder, be installed between pallet (3) and anchor cable lock (5), other operations are identical with anchor cable installation procedure；
3, in work exploitation process, when needing to move back anchor, tap staggered phase button with hammer and move back the convex shape (6) of anchor ring, make two to move back anchor ring to drop between pallet (3) and anchor cable lock (5), the most just a compensation space is provided for lockset (5) axially-movable, such that it is able to take off lockset (5), it is achieved move back anchor.
