Abstract
The invention discloses a kind of fiber rope end casting consolidation method, comprise fiber rope and joint, is scattered in fiber rope one end, be folded and spliced, bitter end portion is increased thick; Local, fiber rope end is increased slightly and penetrates from the small-caliber end of joint, the fiber strand of the fiber rope penetrated in joint is fallen apart into taper, is evenly distributed in pouring cup, ready resin is slowly poured into, the end of fiber rope and joint are consolidated.Butt joint and the pre-stretch-draw of fiber rope thickened portion, make the fiber uniform force of thickened portion, to improve overall rupture pull force.The end of a kind of fiber rigging of the invention connects resin consolidation method, the method is by selecting suitable resin, and joint and the solidified portion local of band reverse taper holes increase thick casting, improve rigging consolidation strength, to reach the object of fiber rigging equal strength casting, thus improve fiber utilization rate.
Description
Technical field
The present invention relates to a kind of fiber rope end casting consolidation method, belong to soft rigging manufacturing technology field.
Background technology
Along with the develop rapidly of fibre manufacturing technology in modern times, the Application Areas of fibrecord is increasingly extensive, and especially, coming out one after another of the high-strength materials such as ultra-high molecular weight polyethylene, the fiber rigging made is applied, and instead of rope rig to a certain extent.And the end consolidation of fiber rigging, main dependence is spliced the method for rope sling, method is single, impact is promoted the use of, and in the place of all use casting consolidations of having to, the tensile strength of joint binding site, have and reduce in various degree, material property is not in full use, and for some widely used new materials, such as, ultra-high molecular weight polyethylene etc., the strength of materials is high, with the poor again in conjunction with firmness of binding agent of casting, make the reduction of casting consolidation strength fairly obvious, strongly limit applying of casting fiber rigging.
Summary of the invention
In order to make joint casting have uniform strength design with cordage, improving fiber utilization rate, to promote the application of fiber casting rigging, the invention provides a kind of fiber rope end casting consolidation method.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of fiber rope end casting consolidation method, comprises fiber rope and joint, is scattered fiber rope one end, be folded and spliced, bitter end portion is increased thick; Local, fiber rope end is increased slightly and penetrates from the small-caliber end of joint, the fiber strand of the fiber rope penetrated in joint is fallen apart into taper, is evenly distributed in pouring cup, ready resin is slowly poured into, the end of fiber rope and joint are consolidated.
Butt joint and the pre-stretch-draw of fiber rope thickened portion, make the fiber uniform force of thickened portion, to improve overall rupture pull force.
The end of a kind of fiber rigging of the invention connects resin consolidation method, the method is by selecting suitable resin, and joint and the solidified portion local of band reverse taper holes increase thick casting, improve rigging consolidation strength, to reach the object of fiber rigging equal strength casting, thus improve fiber utilization rate.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the fiber rope fracture mode schematic diagram that existing casting method manufactures.
Fig. 2 is that scatter structural representation in cordage end described in the embodiment of the present invention.
Fig. 3 is the structural representation that described in the embodiment of the present invention, cordage end anti-plug enters to restrict in body.
Fig. 4 chops rear cordage structural representation off.
Cordage structural representation when Fig. 5 is casting.
Detailed description of the invention
As shown in Figure 1, usually, the casting of fibrous material, affects larger by factors such as cast material intensity.General lower tenacity fibers rupture pull force test value impact is less, part may can reach cable body intensity; And for superhigh intensity fiber, because the strength of materials is far longer than cast material intensity, fiber extends in casting material, cause part overloading, make rope disrumpent feelings in cup inside, thus, do not reach the rupture strength of rope body.Such as: superhigh molecular weight polyethylene material rope body, pouring cup rupture pull force only reaches cable body rupture pull force about 70%.Below, be the casting test done for superhigh molecular weight polyethylene material rope:
Get the common superhigh molecular weight polyethylene material rope of diameter an about 35mm, its cable body rupture pull force value is about 100 tons (100 tons of rupture pull force rope body diameter 33.5mm that international outstanding rope is announced).After rigging casting, tested by static load rupture pull force, adopt different casting material to contrast, best result is no more than 80 tons.
Theoretical according to the present invention, by end overstriking 30%, rope body local reaches 45mm, as Fig. 1: do rupture test after casting, cable body dead load rupture pull force enough exceedes the minimum breaking force of rope body, reaches 103.2 tons.
Below, composition graphs 2-5, is cast into example with a 35mm diameter ultra-high molecular weight polyethylene rigging, manufacturing process is described:
First, select the cordage that a stereotyped writing superhigh molecular weight polyethylene material makes, the two ends of rope are shattered into stereotyped writing by diameter 35mm, see Fig. 2, per share for stereotyped writing cutter is removed 2/3, and anti-plug enters to restrict in body, formed as Fig. 3 structure, then end is chopped off, as shown in Figure 4.
The second, select a small-caliber end aperture 48mm to be with terminal lug (ear facilitates tension test and disrumpent feelings experiment), taper hole length is about about 216, and tapering gets 14 degree.Then, the small-caliber end of cordage from joint is penetrated, then cordage is fallen apart into taper, fiber is dispersed in taper hole, and keep rope coaxial with taper hole, as shown in Figure 5.
3rd, select a kind of high-intensity resin, as LY3600CI/LY3600CI-2, about 1.2 kilograms, filled stone sand 2.0 kilograms, cold casting, by the fiber in pouring cup, intersperses, as far as possible uniformly as Fig. 2:
4th, be heated to 70 DEG C of insulations to Casting Joint and thickened portion and naturally cool for 2 hours, then pre-stretch-draw, makes the fiber uniform force of thickened portion.
Claims (1)
1. a fiber rope end casting consolidation method, comprises fiber rope and joint, is scattered fiber rope one end, be folded and spliced, and bitter end portion is increased thick; Local, fiber rope end is increased slightly and penetrates from the small-caliber end of joint, the fiber strand of the fiber rope penetrated in joint is fallen apart into taper, be evenly distributed in pouring cup, ready resin is slowly poured into, the end of fiber rope and joint are consolidated, butt joint and the pre-stretch-draw of fiber rope thickened portion, make the fiber uniform force of thickened portion, to improve overall rupture pull force.
