It is small, exclude insecurity factor caused by gas and coal dust accumulation.
Utility model content
For various deficiencies of the prior art, to solve the above-mentioned problems, it is proposed that a kind of structure is simple, it is easy to use and
Safe and reliable Mine anchorage cable moves back anchor device, can quickly return anchorage, pallet etc., realizes effective recycling of anchorage material,
Avoid the security hidden troubles such as the accumulation of gas and coal dust present in mine.
To achieve the above object, the utility model provides the following technical solutions:
A kind of Mine anchorage cable moves back anchor device, including sleeve and nut, and the inside of the sleeve is set as hollow structure to be formed
Inner hole, outer wall are equipped with external screw thread, and the nut is sheathed on sleeve periphery, and nut and bush whorl cooperate, the inner hole
Hole wall form multiple continuous circular arcs to the outer wall depression of sleeve, and inner hole is set as the spiral shell to match with anchor cable steel strand wires orientation
The number of trepanning structure, the circular arc is identical as the number of share of stock of anchor cable steel strand wires；
When anchoring, for the anchor device that moves back between anchor cable pallet and strand tapered anchorage, the sleeve is sheathed on anchor cable steel
Twisted wire periphery, top are embedded in inside anchor cable pallet, and bottom is embedded in inside strand tapered anchorage, the top of the nut and anchor cable
Pallet offsets, and offsets at the top of bottom and strand tapered anchorage.
Further, the height of the sleeve is greater than the thickness summation of anchor cable pallet and nut.
Further, the middle part of the anchor cable pallet is equipped with through-hole, and the aperture of the through-hole is greater than the outer diameter of sleeve, and through-hole
Aperture be less than nut outer diameter.
Further, the strand tapered anchorage be include anchor cup and intermediate plate, anchor cup inner hole, the anchor are equipped with inside the anchor cup
Cup inner hole, the longitudinal section of intermediate plate are tapered.
Further, in the bottom insertion anchor cup inner hole of the sleeve, the aperture of the anchor cup inner hole is greater than the outer diameter of sleeve,
And the aperture of anchor cup inner hole is less than the outer diameter of nut.
The beneficial effects of the utility model are:
The displacement for promoting sleeve to generate vertical direction by turning nut, to realize that anchor cable pallet, anchorage and anchor cable steel twist
The utensils such as line quickly and effectively recycle, and to reuse, reduce economic costs, save the material expenditure of mine, meanwhile, operation
Simply, it realizes quickly being caving for top plate, releases stress, can avoid the security risks such as the accumulation of gas and coal dust present in mine and ask
Topic.

Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to the utility model
Attached drawing carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this field is general
Logical technical staff other similar embodiments obtained without making creative work, all should belong to the application
The range of protection.In addition, the direction word mentioned in following embodiment, such as "upper" "lower" " left side " " right side " etc. are only with reference to attached drawing
Direction, therefore, the direction word used is for illustrative and not limiting the invention.
The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.
Embodiment one:
As shown in Figs. 1-2, a kind of Mine anchorage cable moves back anchor device, including sleeve 1 and nut 2, and the inside of the sleeve 1 is set as
Hollow structure is to form inner hole 9, and outer wall is equipped with external screw thread, and the nut 2 is sheathed on 1 periphery of sleeve, and nut 2 and sleeve
1 is threadedly engaged.
When anchoring, the drilling 7 being embedded in for anchor cable steel strand wires 8 is opened up inside country rock 6, meanwhile, anchor cable is arranged in anchor cable steel strand wires 8
Pallet 3 and strand tapered anchorage, the anchor device that moves back is between anchor cable pallet 3 and strand tapered anchorage.In the anchor cable pallet 3
Portion is equipped with through-hole, and the aperture of the through-hole is greater than the outer diameter of sleeve 1.The sleeve 1 is sheathed on 8 periphery of anchor cable steel strand wires, top
Portion is embedded in inside anchor cable pallet 3, and bottom is embedded in inside strand tapered anchorage.Meanwhile the aperture of through-hole is less than the outer diameter of nut 2,
The top of the nut 2 offsets with anchor cable pallet 3, offsets at the top of bottom and strand tapered anchorage, that is to say, that nut 2 is hanging down
Histogram is to can not generate displacement.Specifically, it includes anchor cup 4 and intermediate plate 5 that the strand tapered anchorage, which is, it is equipped with inside the anchor cup 4
Anchor cup inner hole, the anchor cup inner hole, the longitudinal section of intermediate plate 5 are tapered, and the aperture of the anchor cup inner hole is greater than the outer of sleeve 1
Diameter, and the aperture of anchor cup inner hole is less than the outer diameter of nut 2, the bottom of the sleeve 1 is embedded in anchor cup inner hole, 2 bottom of nut
It offsets at the top of portion and anchor cup 4.
When needing to move back anchor, nut 2 is rotated using spanner, since nut 2 is clamped by anchor cable pallet 3 and anchor cup 4, is caused
