Abstract
The invention discloses an expansion-shell anchor rope which is characterized in that a steel wire sleeve is sleeved onto the upper end of a steel strand, a conical pressure sleeve provided with a conical drum on the outer surface is disposed on the periphery of the steel wire sleeve, and the conical pressure sleeve is integrally pressed through the steel wire sleeve and the steel strand. A conical shell is sleeved outside the conical pressure sleeve. An inner conical face which is mutually nested with the conical pressure sleeve is formed on the inner periphery of the conical shell. The lower portion of the conical shell is evenly divided into three pieces. The upper portion of the conical shell is fixedly connected with an anchor rod. A steel strand socket is reserved on the lower end face of the anchor rod. The upper end of the steel strand is inserted into the steel strand socket to drive the anchor rod to rotate. The expansion-shell anchor rope is reliable in anchoring performance and high in anchoring force, is capable of increasing mounting and anchoring depth of the anchor rope greatly, and is widely applicable to tunnel supporting of coal mines with various lithology and various geological conditions.
Description
Technical field
The present invention relates to a kind of mechanical anchor anchor cable that is applied to the colliery shaft and drift supporting.
Background technology
The anchoring process of colliery shaft and drift supporting stream line mainly adopts resin anchoring.But in running into the roadway country rock, water is arranged, or the roadway country rock is when being weak coal rock layer, adopts the resin anchoring can the serious anchoring property that reduces anchor cable.In addition, also there is following problem in the resin anchoring anchor cable that adopts at present: the one, and anchoring agent difficult installation, the anchoring agent that has can not all successfully arrive anchorage point, causes anchor cable partly to lose anchor; The 2nd, receive the high restriction in lane, the anchorage length of anchor cable is restricted, and then the anchored force of raising anchor cable is restricted; The 3rd, anchoring agent packaging bag can not all be stirred broken, influence and reduction anchor cable adhesion stress.
Summary of the invention
The present invention provides a kind of bloated shell-type anchor cable, to remedy the weak point that existing anchorage cable anchoring is deposited.
The design feature of the bloated shell-type anchor cable of the present invention is: the suit steel wire cover in the upper end of steel strand; Periphery at said steel wire cover is provided with the taper gland; Said taper gland is that external surface is the conically shaped little, that go up the big end of going to the bottom, and it is an integral body that said taper gland press-fits with steel strand through the steel wire cover; At the outside suit conical lobe shell of said taper gland, said conical lobe shell is to be formed with the big and inner conical surface mutually nested with the taper gland of little, the upper base of going to the bottom interior week; The bottom of said conical lobe shell is for evenly to be divided into three valves along circumference, and the top and the anchor rod of conical lobe shell are fixedly connected; On the lower surface of said anchor rod, be provided with the steel strand embedded hole, the upper end intercalation of said steel strand is used to drive the rotation of anchor rod in said steel strand embedded hole.
The design feature of the bloated shell-type anchor cable of the present invention also is: the external surface rolling at said conical lobe shell has screw thread.
Compared with present technology, beneficial effect of the present invention is embodied in:
The present invention adopts the mode of mechanical anchor, and anchoring property is reliable, anchored force is strong, can improve the installation and the anchorage depth of anchor cable greatly; Can be widely used in the roadway support under all kinds of lithology in colliery and the various geological conditions, mounting means is simple, and installation process is convenient and swift.

Label among the figure: 1 steel wire cover; 2 steel strand; 3 taper glands; 4 conical lobe shells; 5 anchor rods; 6 steel strand embedded holes; 7 resin anchoring sections; 8 borings; 9 backing plates; 10 ground tackles.
The specific embodiment
Referring to Fig. 1, the structure of the shell-type anchor cable that expands in the present embodiment is set to:
Suit steel wire cover 1 in the upper end of steel strand 2, in the periphery of steel wire cover 1 taper gland 3 is set, taper gland 3 be external surface be go to the bottom little, go up the conically shaped at the big end, it is an integral body that taper gland 3 press-fits with steel strand 2 through steel wire cover 1;
At the outside suit conical lobe shell 4 of taper gland 3, conical lobe shell 4 is to be formed with big and mutually nested with taper gland 3 inner conical surface of little, the upper base of going to the bottom interior week; The bottom of conical lobe shell 4 is for evenly to be divided into three valves along circumference, and the top of conical lobe shell 4 and anchor rod 5 are fixedly connected;
On the lower surface of anchor rod 5, be provided with the steel strand embedded hole, the upper end intercalation of steel strand 2 is used to drive the rotation of anchor rod in the steel strand embedded hole.
In the practical implementation, screw thread is arranged, to increase the anchored force with hole wall in the external surface rolling of conical lobe shell 4.
Installation process:
1, at first to the boring resin anchoring agent isometric of packing in 8, utilize the bloated shell-type anchor cable that has assembled completion that resin anchoring agent is pushed into foot of hole then with anchor rod 5.
2, steel strand 2 are connected with rig, start rig, at this moment; The upper end intercalation of steel strand 2 is in steel strand embedded hole 6; Utilize the rotation of steel strand to drive anchor rod 5 agitating resin anchoring agent, form resin anchoring section 7, anchor rod 5 together is fixed on foot of hole with conical lobe shell 4.
3, backing plate 9 and ground tackle 10 are installed; Utilize tensioning equipment stretch-draw steel strand 2, in steel strand 2 outside stretch-draw, conical lobe shell and taper gland produce the mutual changing of the relative positions; Because its taper direction is opposite; The conical lobe shell is strutted under the expansion of taper gland, and produces the bloated expansion of deformation, tightly pushes with hole wall.The frictional force that tight extruding produced of lobe shell and hole wall makes anchorage cable anchoring.
Claims (2)
1. bloated shell-type anchor cable; It is characterized in that: at the upper end of steel strand (2) suit steel wire cover (1); Periphery at said steel wire cover (1) is provided with taper gland (3); Said taper gland (3) is that external surface is the conically shaped little, that go up the big end of going to the bottom, and it is an integral body that said taper gland (3) press-fits through steel wire cover (1) and steel strand (2); At the outside suit conical lobe shell (4) of said taper gland (3), said conical lobe shell (4) be formed with in interior week little, the upper base of going to the bottom big and with the mutually nested inner conical surface of taper gland (3); The bottom of said conical lobe shell (4) is for evenly to be divided into three valves along circumference, and the top of conical lobe shell (4) and anchor rod (5) are fixedly connected; On the lower surface of said anchor rod (5), be provided with the steel strand embedded hole, the upper end intercalation of said steel strand (2) is used to drive the rotation of anchor rod in said steel strand embedded hole.
