Static rope with rope core in equilateral arrangement structure

Technical Field

The utility model belongs to the technical field of rescue equipment and specifically relates to a static rope of rope core equilateral arrangement structure.

Background

The static rope is mainly applied to exploration and rescue equipment and is also applied to protective ropes for high-altitude fast descent and rock climbing on the basis of the characteristics of high strength and small elongation, the traditional rope is often only in a single-woven structure and a double-woven structure, the problems of insufficient strength, overlarge elongation and the like exist, and the stable bearing of heavy load cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem, a static rope that limit structure such as rope core was arranged is provided, the technical scheme of its adoption as follows:

the utility model provides a rope core equilateral arrangement structure's static rope, includes rope core and the sheath outside the rope core, the rope core is regular polygon parallel arrangement by many strands and weaves and form, and every strand is merged by many twists and twists the twisting and weave and form, and every twists by many yarns merge the twisting and weave and form.

Preferably, the number of strands is 3.

Preferably, each strand is braided by an 8-spindle, 12-spindle or 16-spindle braiding machine.

Preferably, the rope core and the sheath are made of nylon, terylene or aramid.

Preferably, the diameter is 8.5-16mm, the diameter of the sheath accounts for 25% -55%, the number of yarn ends of the rope core is 10-70, and the number of yarn ends of the sheath is 10-70.

The beneficial effects of the utility model are that: rope core adopts 3 strands to constitute equilateral stable structure, and effective dispersion exerts the external force on quiet power rope, provides the fracture brute force of far away super average destructive power, keeps compact structure, possess more stable control power, avoids the sheath to take place to slide, can with accord with EN 341:2011 standard equipment is perfectly matched, has better braking force and stable speed under the condition of high load operation; through pre-drafting and post-treatment, the elongation of the fiber is reduced while the strength is improved, and the requirement of high strength and low elongation is met.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

in the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrated; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present invention, it is to be understood that the terms "center", "length", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the present application, unless expressly stated or limited otherwise, the recitation of a first feature "on" or "under" a second feature may include the recitation of the first and second features being in direct contact, and may also include the recitation of the first and second features not being in direct contact, but being in contact with another feature between them. Also, the first feature "on," "above" and "over" the second feature may include the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1 and 2, the static rope with the rope core in the equilateral arrangement structure comprises a rope core 1 and a sheath 2 outside the rope core 1, wherein the rope core 1 is formed by weaving a plurality of strands in a regular polygonal parallel arrangement, each strand is formed by combining, twisting and weaving a plurality of twisted threads, and each twisted thread is formed by combining, twisting and weaving a plurality of yarns. Preferably, the number of the strand ropes is 3, a stable three-equilateral structure is formed, and when the rope is impacted by external force, the three sides are simultaneously stressed, so that the strength of the rope is obviously improved compared with that of a common rope without an equilateral stable structure. Meanwhile, the middle cavity of the three-equilateral stable structure has an even gap structure, and when the middle cavity receives impact force, the middle cavity can effectively disperse the force and absorb the impact energy, so that the requirements of related marking impact force and impact and falling times are met. Each strand is braided by an 8-spindle, 12-spindle or 16-spindle braiding machine. The diameter is 8.5-16mm, the diameter of the sheath 2 accounts for 25% -55%, the number of yarn ends of the rope core 1 is 10-70, and the number of yarn ends of the sheath 2 is 10-70.

The rope core 1 and the sheath 2 are made of nylon, terylene or aramid fiber, so that the oil resistance and chemical corrosion resistance of the rope are effectively improved, and the rope is more suitable for being applied to various severe environments.

The static cords of the examples were tested in performance with conventional static cords according to standard EN1891-1998, personal protective equalisation for the prediction of falls, giving the test results shown in Table 1 under the conditions of a primary impact force of 5.1kN, a number of impacts of 7 and a static strength of 30 kN.
