Problems solved by technology

[0002] Existing equipment processes 600m-160mm ultra-high molecular weight polyethylene (UHMWPE) braided rope with a total length of 600m, which cannot provide a whole braided rope with an anchoring length of 800m-3000m for deepwater drilling platforms and 6000m for ultra-deep water; and At present, the technology of manufacturing super-large rope-making equipment is immature; the super-long braided anchor rope is currently obtained by using the method of cross-socket connection of rope strands, and the double braided layer is used for sand prevention treatment. The defect is that the rope elongation is large and unstable, and sea sand enters the anchor. After the cable is re-braided, it is easy to cut the anchor cable fiber and reduce the service life

Embodiment Construction

[0006] Use UHMWPE fiber with a linear density of 200dtex-5000dtex (single fiber linear density 2dtex-12dtex), and twist it into a 400dtex-20000dtex rope yarn on a constant tension twister;

[0007] 400dtex-20000dtex UHMWPE fiber rope yarn is twisted into 20-40 twist / m non-joint strands under the tension of 20%-60% rope yarn strength;

[0008] On the 8-12 braiding machine, twist into 8-12 strands of 60-160mm in diameter and 800m-6000m in length with a diameter of 1 / 3 of the anchor cable and a twist coefficient of 5-20;

[0009] Each braided rope core is treated with polyurethane glue dipping, the dipping amount is 5-10% of the weight of the braided rope core, and dried naturally for 24-48 hours; then arranged in three layers to form anchor cable cores;

[0010] Wrap it with a polyester non-woven fabric with a total thickness of 3mm-5mm ultra-fine filter effect, and then dry it naturally for 48-96 hours;

[0011] Use a 24-48-ply braiding machine to weave the strands twisted fro...

Abstract

The invention discloses a sand-proof anchor cable with three layers of parallel ultra-high molecular weight polyethylene fiber braided rope cores and relates to textile cables. A rope formed by braiding polyester fiber single-stranded and double-stranded rope strands and ultra-high molecular weight polyethylene (UHMWP) 8 to 12-strand braided ropes is adopted. The sand-proof anchor cable is characterized in that: as an outer layer, the polyester fiber single-stranded and double-stranded rope strand is braided on the three layers of parallel inner cores which are formed by braiding the UHMWP 8 to 12-strand braided ropes; the rope strands of the inner cores do not have joints; the outer layer and the inner cores are impregnated in a polyurethane adhesive; and a polyester non-woven fabric wraps on the three layers of parallel inner cores to form a middle sand-proof layer. The sand-proof anchor cable is used for anchoring ocean engineering super-long towropes, is applied to framework steel cables of deep sea fishery, such as high-opening and middle-layer dragnets, large seines and the like, is applied to special ocean engineering, such as deep sea salvage, sea exploration and the like, and is applied to projects, such as aerospace military, traffic shipping, industry, agriculture, mines and the like.

Description

technical field [0001] The invention belongs to textile ropes. Background technique [0002] Existing equipment processes 600m-160mm ultra-high molecular weight polyethylene (UHMWPE) braided rope with a total length of 600m, which cannot provide a whole braided rope with an anchoring length of 800m-3000m for deepwater drilling platforms and 6000m for ultra-deep water; and At present, the technology of manufacturing super-large rope-making equipment is immature; the super-long braided anchor rope is currently obtained by using the method of cross-socket connection of rope strands, and the double braided layer is used for sand prevention treatment. The defect is that the rope elongation is large and unstable, and sea sand enters the anchor. After the cable is re-braided, it is easy to cut the anchor cable fiber and reduce the service life. Contents of the invention [0003] The object of the present invention is to provide an ultra-high molecular weight polyethylene three-l...
