Abstract
The utility model provides a high anchor-hold anchor cable, comprising a steel strand, a clamp sheathed with the steel strand and an anchorage section, wherein the steel strand is made of steel wires; a steel wire in the middle of the anchorage section is orderly sleeved by hexagon nuts, two hexagon nuts are combined into one body with the support of a steel pipe; the other steel wires are orderly abutted with each angle of the nuts, which makes the anchorage section form a jujube-stone shaped structural body. Compared with the prior clamp type anchor cable, the utility model enlarges the diameter of the steel strand, thereby making the steel strand capable of completely and evenly stirring up the resin anchoring agent to the utmost, providing the reliable anchoring force, furthermore enhancing the production efficiency and realizes the safe production, hence an ideal high anchor-hold anchor cable for supporting coal mine roadways.
Description
Technical field
The utility model relates to a kind of anchor cable, particularly a kind of colliery tunnel support strong anchoring force anchor cable.
Background technology
At present, the anchor cable that use in the colliery mostly is ф 15.24mm steel strand greatly, resin-bonded anchoring, and its structure is a clamping hoop type.The anchor cable of this structure, its shortcoming is: resin anchoring agent is stirred inhomogeneous insufficient, thereby easily cause anchored force not reach designing requirement, cause anchor cable to lose efficacy, bring hidden danger to safety in production.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of full and uniform stirring that can guarantee effectively resin anchoring agent is provided, the structural drag that increases anchored end reduces the stretch-draw stand-by period, accelerate the anchor cable installation rate, the strong anchoring force anchor cable of reliable anchored force is provided.
The purpose of this utility model is achieved in that and comprises the clip that is sleeved on the steel strand, steel strand, anchoring section, wherein steel strand are made up of steel wire, its structural feature is that according to being with hex nut, two nuts support to one by steel pipe on a steel wire in the middle of the anchoring section, remaining steel wire apical grafting according to the order of sequence makes anchoring section constitute jujube nutty structure body on each angle of nut.
Compare with existing clamping hoop type anchor cable, the utility model has increased the steel strand diameter, makes it provide reliable anchored force to greatest extent with the full and uniform stirring of resin anchoring agent.The variation of anchoring section structure can provide good structural drag.The fat edges structure of clip also can play an important role to the stirring of resin anchoring agent simultaneously, and the combination of several structures can greatly improve anchored force, and then enhances productivity, and realizes safety in production.
The explanation of accompanying drawing drawing
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is by clip 5, anchor cable section 6 compositions such as grade.Clip 5 be two ends all with the clip of fat edges 4, according to designing requirement a plurality of being sleeved on the steel strand can be set.Steel strand are made up of seven steel wires, wherein on a steel wire in the middle of the anchoring section, be with hex nut 1 successively, two hex nuts 1 support to one by steel pipe 2, remaining six roots of sensation steel wire according to the order of sequence apical grafting on each angle of nut 1, just head on steel wire respectively on six of nut 1 angles, anchoring section 6 is strutted formation jujube nutty structure as accompanying drawing.Make gauge of wire by original ф 15.24mm, become ф 21mm.
Preparation method of the present utility model is; Earlier some circular clips 5 are inserted in steel strand, then steel strand anchoring section 6 is taken apart, therebetween on straight line steel wire, be inserted in nut 1, steel pipe 2, nut 1 successively, nut 1 and steel pipe 2 play the effect of spreading steel strand and steel wire jointly, then the steel strand of taking apart are compiled back original state, have so just formed a jujube nutty structure body, the clip that will in advance be inserted in is suppressed on mould at last, suppresses fat edges 4.
Claims (2)
1, a kind of strong anchoring force anchor cable, comprise the clip that is sleeved on the steel strand, steel strand, anchoring section, wherein steel strand are made up of steel wire, it is characterized in that, on a steel wire in the middle of the anchoring section, comply with and be with hex nut, two nuts support to one by steel pipe, and remaining steel wire apical grafting according to the order of sequence makes anchoring section constitute jujube nutty structure body on each angle of nut.
2, strong anchoring force anchor cable according to claim 1 is characterized in that clip is provided with a plurality of, and the two ends of each clip all have fat edges.
