Abstract
The invention relates to an integrated composite anchor with high intensity, which solves the problem that because in prior composite anchor the bar is connected with the nut in screw thread fit with partial structure and the prescription of composite is not reasonable, the intensity of anchor is bad and it is broken at the connection position of screw thread by shear force or the nut is cracked in ring direction. It comprises composite bar body with screw thread, nut and pallet. The nut is molded to form at the end of bar directly. The composite constituting nut comprises 35%-42% of short glass fiber by wt, 30%-35% of 191# or 196# resin by wt, 2%-4% of methyl ethyl copper peroxide by wt, 3%-7% of isooctanoic cobalt styrene, 15%-20% of calcium carbonate by wt, 6%-12% of aluminum hydroxide by wt and 2%-6% of antistatic agent by wt. the invention can improve the intensity of composite anchor greatly. By using test for a long time, phenomena of shear breaking at the connection position of screw thread or ring crack of nut does not appear in the composite anchor.
Description
Technical field
The present invention relates to be used for the suspension device of mine working, highway, railway tunnel and slope retaining---anchor pole, be specially a kind of high-strength integral composite material anchor shaft.
Background technology
Anchor pole is the supporting articles for use of a kind of mine working, highway, railway tunnel and side slope, the anchor pole material of Shi Yonging mainly is wooden, bamboo matter and steel etc. in the past, though wooden or bamboo made anchor rod is in light weight, cost is low, the low supporting effect of intensity is poor, apt to rot, application life is short; Though steel anchor pole intensity height, supporting effect are better, but also there are two big defectives in the steel anchor pole, promptly very easily corroded and reduce intensity and, cause the local gas blast because of coal-winning machine cut and anchor pole collision produce spark, bring potential safety hazard for the mining production operation.
From the nineties beginning in last century, developed multiple composite material anchor shaft in succession, wherein glass fibre reinforced plastics rockbolts is in light weight because of it, cost is low, corrosion-resistant, the life-span long, characteristics such as safe in utilization and easy for installation, having begun to replace gradually the uses on mine working, highway, railway tunnel and side slope such as conventional metals anchor pole and bamboo and wood matter anchor pole, is the developing direction of present bolt support articles for use.
Existing composite material anchor shaft and steel anchor structure are similar, are made up of the threaded composite material body of rod, nut and pallet.Composite material adopts glass fiber reinforced plastic mostly.Be the split-type structural of threaded engagement between the body of rod of existing composite material anchor shaft and the nut, during use supporting plate be placed on the body of rod, again nut is twisted in body of rod lower end; Because the screw thread between the body of rod and the nut is the coarse-pitch thread that forms in the composite material forming process, or is the threaded engagement tension, nut can't be screwed on, or is that Screw Thread Fit Clearance is excessive, causes the shear failure of screw thread junction, forms nut and threads off; Simultaneously, because the prescription of composite material is unreasonable, the body of rod particularly tension, the torsional strength of nut itself is lower, often causes the nut hoop to ftracture.Adopted some improving technologies to overcome above-mentioned defective at present: 1, to reprocess screw thread in the body of rod appearance of coarse-pitch thread, as through the body of rod appearance reshaping screw thread of secondary mould pressing at coarse-pitch thread, but differ because of two kinds of material properties so again, bonding interface is unreliable, tension, torsional strength still are difficult to be up to state standards, and complex process, processing cost height, and the mold pressing external screw thread is second-rate, still has above-mentioned nut and the threaded engagement problem between the body of rod.2, on the coarse-pitch thread body of rod, overlap metal tube, outside metal tube, reprocess screw thread; But so not only complex process, processing cost height, and coal-winning machine cut tool and the easy spark that produces of anchor pole collision cause the local gas blast.
Summary of the invention
The present invention for solve existing composite material anchor shaft because of poor between the body of rod and the nut for the unreasonable anchor rod strength that causes of the prescription of the split-type structural of threaded engagement, composite material, often shear failure of screw thread junction or nut hoop problems of crack take place, a kind of high-strength integral composite material anchor shaft is provided.
The present invention adopts following technical scheme to realize: high-strength integral composite material anchor shaft, to form by the threaded composite material body of rod, nut and pallet, and the direct compression molding of nut is in the end of the body of rod; The composite material that constitutes nut is to constitute with following raw materials by weight percent: short glass fiber 35%-42%, 191# or 196# resin 30%-35%, peroxidating first and second bronze medals (as curing compound) 2%-4%, different cobalt green styrene (as accelerator) 3%-7%, calcium carbonate (as filler) 15%-20%, aluminium hydroxide (as fire retardant) 6%-12%, antistatic additive 2%-6%.Wherein, different cobalt green styrene is that different cobalt green is with the solution of arbitrary proportion in styrene.
For further improving the intensity of anchor pole, the composite material that constitutes the body of rod is to constitute with following raw materials by weight percent: continuous glass fibre bundle 50%-57%, short glass fiber 5%-10%, 191# or 196# resin 25%-35%, peroxidating first and second bronze medals (as curing compound) 1%-2%, different cobalt green styrene (as accelerator) 2%-3%, aluminium hydroxide (as fire retardant) 3%-6%, antistatic additive 2%-6%.
During manufacturing, make body of rod composite material with raw material existing or of the present invention, proportioning, carry out body of rod moulding with prior art, be about to the nib that composite material passes existing pultrusion mould, make cross section and the surperficial body of rod that coarse-pitch thread arranged identical with the nib shape, length is blocked in accordance with regulations, makes the composite material body of rod.Make the composite material of nut with above-mentioned raw material, proportioning, with the direct compression molding of nut in the end of the body of rod, thereby make the anchor pole of the body of rod and nut one.With the NUT FORMING DIES of composite material molded be that those skilled in the art realize easily in body of rod end.
The present invention in structure design and the nut of optimization and the composite-material formula of the body of rod of the end of the body of rod, has greatly improved the intensity of composite material anchor shaft by the direct compression molding of nut.Through long service test, shear failure of screw thread junction or nut hoop cracking phenomena do not take place in this composite material anchor shaft.Composite material anchor shaft of the present invention has the product strength height, manufacture craft is simple, safe and reliable and low cost and other advantages, and wide application prospect is arranged.
