Description

Polyester-polypropylene mixed rope

Technical Field

The utility model relates to the technical field of cables, in particular to a polyester-polypropylene mixed rope.

Background

In the field of shipping of ships, oil tankers, port hauling and the like, cables are required, and in order to avoid the cables sinking into water, ship mooring cables are usually made by twisting with floating fibers (polypropylene fibers) with specific gravity less than 1. However, if the cable is twisted by polypropylene, the cable is not strong enough and is easy to break, so that the cable has high strength and does not sink into the water.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a polyester-polypropylene mixed rope which has high strength, is not easy to break and can float on the water surface.

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model provides a polyester-polypropylene mixed rope, includes polyester rope core, twists stranded polypropylene rope on polyester rope core, polyester rope core's diameter is greater than polypropylene rope's diameter, every equidistant seam has the button on the polypropylene rope, it has the rope strap to tie on the button, it has the floater to tie on the rope strap.

Preferably, the periphery of the polypropylene rope is coated with a waterproof film, and the waterproof film can be polyurethane waterproof paint.

Preferably, the polyester rope core comprises a first polyester strand in the center and a plurality of second polyester strands twisted on the periphery of the first polyester strand, and cables with different intensities can be produced according to the difference of the numbers of the second polyester strands.

Preferably, the number of the second polyester strands is seven.

Preferably, the number of the polyester strands is eleven.

Preferably, the polypropylene rope comprises a first polypropylene fiber strand in the center and six second polypropylene fiber strands twisted outside the first polypropylene fiber strand.

Compared with the prior art, the utility model has the following beneficial effects:

the rope core adopts polyester, has the characteristics of high strength, good elasticity, wear resistance and corrosion resistance, the stranded polypropylene rope is twisted on the polyester rope core, the polypropylene rope is smooth in shape and low in density, is less than 1g/cm < 3 >, is easy to float on the water surface, and the polypropylene rope surrounds the polyester rope core, so that the polyester rope also has a protective effect, and can well float on the water surface and prevent sinking while the strength is increased.

The rope buckles are arranged on the polypropylene wheel rope at certain intervals, and the rope belts are tied on the rope buckles, so that floating balls can be tied on the rope belts according to the requirements, the buoyancy of the cable is further improved, and sinking is prevented.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, a polyester-polypropylene hybrid rope comprises a polyester rope core 1 and a plurality of polypropylene ropes 2 twisted on the polyester rope core 1, wherein the diameter of the polyester rope core 1 is larger than that of the polypropylene ropes 2, rope buckles 3 are sewn on the polypropylene ropes 2 at equal intervals, rope belts 4 are tied on the rope buckles 3, floating balls 5 are tied on the rope belts 4, a waterproof film 6 is coated on the periphery of the polypropylene ropes 2, and the waterproof film 6 is polyurethane waterproof paint and is coated on the periphery of the polypropylene ropes 2. The rope core adopts polyester, has the characteristics of high strength, good elasticity, wear resistance and corrosion resistance, the stranded polypropylene rope 2 is twisted on the polyester rope core 1, the polypropylene rope is smooth in shape and low in density, is less than 1g/cm < 3 >, is easy to float on the water surface, and the polypropylene rope 2 surrounds the polyester rope core 1, so that the polyester rope also has a protective effect, and can float on the water surface well while the strength is increased, and sinking is prevented. The rope buckles 3 are arranged on the pulley rope 2 at certain intervals, and the rope belts 4 are tied on the rope buckles 3, so that the floating balls 5 can be tied on the rope belts 4 according to the requirement, thereby further improving the buoyancy of the cable and preventing sinking.

Referring to fig. 3, a first embodiment of a polyester rope core 1 is shown, wherein the polyester rope core 1 includes a first polyester strand 11 in the center and seven second polyester strands 12 twisted around the first polyester strand 11.

Referring to fig. 4, a second embodiment of the polyester rope core 1 is shown, wherein the polyester rope core 1 includes a first polyester strand 11 in the center and eleven second polyester strands 12 twisted around the first polyester strand 11.
