Embodiment Construction

[0014] Such as figure 1 As shown, in general, the casting of fiber materials is greatly affected by factors such as the strength of the casting material. Generally, the breaking force test value of low-strength fibers has little influence, and may partially reach the strength of the cable body; while for ultra-high-strength fibers, because the material strength is much greater than that of the casting material, the fibers extend in the casting material, causing local overload, making the rope It breaks inside the cup body, thereby failing to reach the breaking strength of the rope body. For example: the UHMWPE material rope body, the breaking force of the casting cup only reaches about 70% of the breaking force of the cable body. The following is a casting test for UHMWPE material ropes:

[0015] Take an ordinary ultra-high molecular weight polyethylene material rope with a diameter of about 35mm, and its breaking force value is about 100 tons (the 100-ton breaking force rop...

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 [0001] The invention relates to a method for casting and consolidating fiber rope ends, which belongs to the technical field of soft rigging manufacturing. Background technique [0002] With the rapid development of modern fiber manufacturing technology, the application fields of fiber ropes are becoming more and more extensive. In particular, the successive appearance of high-strength materials such as ultra-high molecular weight polyethylene makes the application of fiber rigging replace steel wire rope rigging to a certain extent. . The end consolidation of fiber rigging mainly depends on the method of inserting and knitting rope sleeves. The method is single, which affects the popularization and use. In all places where casting consolidation has to be used, the tensile strength of the joint joints has different degrees. Reduced, so that the material properties can not be fully utilized, and for some widely used new materials, such as ultra-high molecular...
