The specific embodiment
In the embodiment shown in fig. 1, the utility model Mine anchorage cable is by stirring-head (1), anchor cable body (2), adapter sleeve (3), pallet (4), nut (5) be connected spring (6) and constitute.
Anchor cable body (2) is to use the steel hinge line of being twisted with the fingers by many steel wires to make.Be with a stirring-head (1) on the head of anchor cable body (2); The afterbody of anchor cable body (2) is with adapter sleeve (3), accompanies between anchor cable body (2) and the adapter sleeve (3) to be connected spring (6), and the three is closely as one through extruding.Threaded on the external surface of adapter sleeve (3), be equipped with nut (5) on it, pallet (4) is enclosed within on the adapter sleeve (3).
Fig. 2 shows the structure that connects spring (6).It is one the circular steel bushing that vertically cracks to be arranged.Vertically crack in Fig. 2, be positioned at steel bushing front side middle part, in horizontal direction, parallel with center line.On the inside and outside surface of connection spring (6) steel bushing band annular line cusped edge, vertical with the axial line of steel bushing (8,7) is arranged all, similar with the thread form of screw thread; Its hardness is greater than the steel hinge line of anchor cable body (2).The effect that connects spring (6) is the degree of consolidation of strengthening between anchor cable body (2) and the adapter sleeve (3), increases the mechanical strength of the two connecting portion, improves the supporting capacity of anchor cable.Also can be similar projections thing of other band point or cusped edge on the inside and outside surface of connection spring (6) steel bushing, as: interrupted annular line, interrupted screw thread etc.
The length of adapter sleeve (3) is 80～200mm, and the length of adapter sleeve should be than connecting the big at least 25mm of spring (6) length.Anchor cable body (2) is not less than 95% of anchor cable body (2) intensity with the intensity of adapter sleeve (3) connecting portion.
Fig. 3～5 show the structure of stirring-head (1).It is the tubular article of a top band pawl, and its external diameter is less than bore diameter, and the external diameter of internal diameter and anchor cable body (2) is complementary, and top is center plug with holes (11).Pawl (12) on plug (11) top is four, and the direction of these pawls (12) is also outward-dipping vertically, arc enveloping surface of the common formation of their medial surface; Pawl point to the distance of axis is the maximum radius of stirring-head (1).The external peripheral surface of stirring-head (1) has left-handed cross rib (10).Stirring-head (1) is by the nylon manufacturing, and its inner circumferential surface is provided with the linear fin of reflex (9), and this fin (9) is complementary with the spiral grooves of the steel hinge line external surface of anchor cable body (2).Also can add epoxy resin between stirring-head (1) and the anchor cable body (2) cements.
Fin (9) on stirring-head (1) inner surface is for guarantee that stirring-head (1) rotates with anchor cable in the anchor cable installation process.The cross rib (10) of pawl at stirring-head top (12) and external surface is in anchor cable rotation agitating resin powder stick process, improves the mixing effect and the compactness of anchor cable.
Pawl on the stirring-head (12) is at least two, and the medial surface of these pawls is common to form an arc enveloping surface so that make, and adapts with the arcwall face of anchoring agent powder stick termination.The hole at plug center can be for the bundle head that injects the powder stick end.These characteristics are for ease of holding powder stick, and it successfully is pushed to the boring deep and designs.
In a word, the effect of stirring-head is to make the resin explosive roll installation convenient, and mixing time is short, effective, and anchored force is big, improves the supporting capacity of anchor cable.
The also available steel manufacturing of stirring-head (1), it is enclosed within on the head of anchor cable body (2) and reinforces through extruding.At this moment, do not need to establish fin on the inner circumferential surface of stirring-head (1), need not adding additives between it and the anchor cable body (2), but its inner circumferential surface is coarse, and projection is preferably arranged yet.
Nut (5) adopts quick mounting nut.The intensity of pallet (4) and shape and nut shape coupling, contact will be got well.
Using method:
Mine anchorage cable utilizes its stirring-head, resin explosive roll can be installed to foot of hole quickly and easily, uses roof-bolter directly to stir then, behind the stirring certain hour, loads onto pallet, last jack panel.Realize the Fast Installation of Mine anchorage cable.Requirement makes the Mine anchorage cable protruded length be not more than 10mm.
Processing and manufacturing:
When processing connects spring (6), to process earlier the annular line (8,7) of band cusped edge on the inside and outside surface of steel bushing, Quenching Treatment makes the steel hinge line of its hardness greater than anchor cable body (2) then.
The afterbody of anchor cable body (2) is connected spring (6) with being enclosed within to insert between its outer adapter sleeve (3), by pushing, the three is closely as one, and then, screw thread on adapter sleeve (3) Surface Machining is mixed nut (5).The length of adapter sleeve (3) satisfies the requirement that pretightning force was installed and applied to Mine anchorage cable, and the length that connects spring (6) satisfies the intensity 95% that connecting portion intensity is not less than the anchor cable body.
Stirring-head (1) is when making with nylon, injection mo(u)lding.When the material of stirring-head (1) adopted metal, moulded by casting connected or adhesive method with can pushing being connected of anchor cable body.
