Abstract
The invention discloses a method for casting and solidifying the end portion of a fiber rope. The method relates to the fiber rope and a joint. The method comprises the steps of scattering one end of the fiber rope, folding the end portion in half in an inserting and weaving mode, thickening the end portion of the fiber rope, inserting the partially thickened end portion of the fiber rope from the small-bore end of the joint, scattering fiber strands, inserted into the joint, of the fiber rope into a cone shape, allowing the fiber strands to be evenly distributed inside a casting cup, slowly pouring prepared resin into the casting cup, and allowing the end portion of the fiber rope and the joint to be solidified together. The joint and the thickening portion of the fiber rope are pre-tensioned, and fibers of the thickening portion are evenly stressed so that whole breaking force is improved. The method is used for solidification of the end portion, connected with the resin, of the fiber rope. According to the method for casting and solidifying the end portion of the fiber rope, the proper resin, the proper joint with an inverted-cone-shaped hole and a proper solidification part are selected for partial thickening and casting, solidification strength of the rope is improved so that the aim of equal strength casting of the fiber rope can be achieved, and therefore a fiber use ratio is improved.
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, especially, the coming out one after another of high-strength materials such as ultra-high molecular weight polyethylene, the fiber rigging that makes is used, and has substituted rope rig to a certain extent.And the end of fiber rigging is fixed, the main method of inserting the sennit cover that relies on, method is single, influence is promoted the use of, and have to use the fixed place of casting at all, the tensile strength of joint binding site, have in various degree and reduce, make material property be not in full use, and for some widely used new materials, for example, ultra-high molecular weight polyethylene etc., strength of materials height is with the poor again in conjunction with firmness of binding agent of casting, make that the reduction of casting consolidation strength is fairly obvious, greatly limited applying of casting fiber rigging.
Summary of the invention
In order to make joint casting and cordage have the equal strength design, improve the fiber utilization rate, to promote the application of fiber casting rigging, the invention provides a kind of fiber rope end casting consolidation method.
Purpose of the present invention is come specific implementation by the following technical programs:
Casting consolidation method in a kind of fiber rope end comprises fiber rope and joint, and fiber rope one end is scattered, and doubling is inserted and compiled, and bitter end portion is increased slightly; Part, fiber rope end is increased thick back small-caliber end from joint penetrate, the fiber strand that penetrates the fiber rope in the joint is loose into taper, be evenly distributed in the 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 of thickened portion stressed evenly, to improve whole rupture pull force.
The invention a kind of end of fiber rigging connect the resin consolidation method, this method is by selecting suitable resin, and joint and the fixed part part in band back taper hole increase thick casting, improve the rigging consolidation strength, reaching the purpose of fiber rigging equal strength casting, thereby improve the fiber utilization rate.
Description of drawings
The present invention is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is the fiber rope fracture mode schematic diagram that existing casting method is made.
Fig. 2 is the described cordage of the embodiment of the invention end structural representation that scatters.
Fig. 3 is the anti-structural representation that inserts in the rope body in the described cordage of embodiment of the invention end.
Fig. 4 chops back cordage structural representation off.
Cordage structural representation when Fig. 5 is casting.
The specific embodiment
As shown in Figure 1, usually, the casting of fibrous material is subjected to factor affecting such as cast material intensity bigger.General lower tenacity fibers rupture pull force test value influence is less, may part can reach cable body intensity; And for the superhigh intensity fiber, because the strength of materials is far longer than cast material intensity, fiber extends in casting material, causes local overload, makes rope disrumpent feelings in cup inside, thereby, do not reach the rupture strength of rope body.For example: superhigh molecular weight polyethylene material rope body, pouring cup rupture pull force only reach cable body rupture pull force about 70%.Below, be the casting test of doing at the superhigh molecular weight polyethylene material rope:
Get the common superhigh molecular weight polyethylene material rope about a diameter 35mm, its cable body rupture pull force value is (100 tons of rupture pull force rope body diameter 33.5mm that international outstanding rope is announced) about 100 tons.After the rigging casting, by the test of static load rupture pull force, adopt different casting material contrasts, best result is no more than 80 tons.
The theory according to the present invention, with end overstriking 30 %, rope body part reaches 45mm, and as Fig. 1: do rupture test after the casting, cable body dead load rupture pull force enough surpasses the minimum breaking force of rope body, reaches 103.2 tons.
Below, in conjunction with Fig. 2-5, be cast into example with a 35mm diameter ultra-high molecular weight polyethylene rigging, manufacturing process is described:
At first, the cordage of selecting a stereotyped writing superhigh molecular weight polyethylene material to make, diameter 35mm is shattered into stereotyped writing with the two ends of restricting, see Fig. 2, remove 2/3 with cutter with stereotyped writing is per share, the anti-insertion in the rope body, form as Fig. 3 structure, then the end is chopped off, as shown in Figure 4.
The second, select the terminal lug (ear makes things convenient for tension test and disrumpent feelings experiment) of a small-caliber end aperture 48mm band, taper hole length is about about 216, and tapering is got 14 degree.Then, the small-caliber end of cordage from joint penetrated, again cordage is loose into taper, fiber is dispersed in the taper hole, and keep rope coaxial with taper hole, as shown in Figure 5.
The 3rd, select a kind of high-intensity resin, as LY3600 CI/LY3600 CI-2, about 1.2 kilograms, fill 2.0 kilograms of quartz sands, cold casting, the fiber with in the pouring cup intersperses as far as possible uniformly, as Fig. 2:
The 4th, Casting Joint and thickened portion are heated to 70 ℃ of insulations cooling naturally in 2 hours, pre-stretch-draw then makes the fiber of thickened portion stressed evenly.
Claims (2)
1. a fiber rope end casting consolidation method comprises fiber rope and joint, and fiber rope one end is scattered, and doubling is inserted and compiled, and bitter end portion is increased slightly; Part, fiber rope end is increased thick back small-caliber end from joint penetrate, the fiber strand that penetrates the fiber rope in the joint is loose into taper, be evenly distributed in the pouring cup, ready resin is slowly poured into, the end of fiber rope and joint are consolidated.
2. consolidation method as claimed in claim 1 is characterized in that, butt joint and the pre-stretch-draw of fiber rope thickened portion make the fiber of thickened portion stressed evenly, to improve whole rupture pull force.
