(57) Abstract:

The inventive rope contains located in an outer protective sheath of synthetic strands, each of which is made of modules that represent bundles of filament yarn, twisted yarn. Each strand is additional shell. External and additional sheath strands are woven case in which the warp threads are parallel to the axis of the rope. This design provides increased strength and durability of the rope when it is used as a load-bearing element. 4 Il., 1 tab.

The invention relates to wire ropes of different capacity, for which the load-carrying element used synthetic fibers. Ropes can be used as a ship ropes at deep seabed mining, as well as carrying rigging.

Famous rope, containing situated in an outer protective sheath of synthetic strands, each of which is made from a group of modules that represent bundles of filament yarn, twisted yarn [1].

In the known device the breaking strength of a rope is determined in osnovnoi shell and synthetic strands are different.

The purpose of the invention is the improvement of the strength and durability of the rope.

This is due to the fact that the rope is provided with an additional membranes that surround each group of modules corresponding strands, while the outer protective shell and the additional sheath is made in the form of woven covers, the warp threads which are parallel to the axis of the rope, and the weft threads is perpendicular to this axis, and the modules and strands are also parallel to the axis of the rope.

In Fig.1 presents a unified module load-bearing part of the rope of Fig.2 - strand consisting of modules of Fig.3 - rope Assembly of Fig.4 is a cross - section of the rope.

The rope contains located in an outer protective sheath 1 synthetic 2 strands, each of which is made in the form of a group of modules 3, representing the beams 4 filament yarn, twisted yarn 5. Each group of modules 3 corresponding strands 2 is provided with an additional shell 6. When this outer protective sheath 1 and the additional sheath 6 made in the form of woven covers, the warp threads which are parallel to the axis of the rope, and the weft threads is perpendicular to this axis, and the modules strands are also parallel to the axis of the rope.

In ispolneny of synthetic fibres, with high resistance to abrasion and repeated bending (polyamide or polyester filaments).

Modules 3 and 2 strands are parallel to the axis of the rope. Modules are a bunch RAS-yarn linear density 58.8 Tex, comprehensive wound filament linear density of 187 Tex. The diameter of the module is 2-4 mm, the number of modules in strands from 46 of 100, the number of strands in the rope from 1 to 7. Linear density modules 8340 Tex. The rope can be manufactured in lengths up to 200 m Breaking load of the rope is from 150 to 400 thousand Dan.

Characterization of physico-mathematical indicators known and proposed ropes shown in the table.

The design of the rope allows the use of an outer protective sheath and a protective sheath strands, the warp threads which make up 98% of the weight of the shells, together with the load-carrying elements of the rope strands, modules). This parallel arrangement of strands and modules, consisting of high-modulus synthetic (synthetic) fibres makes it possible to eliminate additional warp strands and modules from repeated bending, which creates favorable conditions for the exception of the loss of strength from Curling modules and locks.

Hakimullah utilization from 0.5 to 0.8.

The design of the rope by 25% increases the durability of the rope.

When you shell rope and strand woven covers actually become the outer layer of each strand and the outer layer of the rope, since the elements (the warp and the weft) woven cover perform several new, non-core functions: ducks, compressing parallel elements, seals structural load-bearing elements (strands and modules), contributing to the improvement of the adhesion forces and friction, which provides simultaneous operation of all power components. When stretching, i.e., during operation of the weft yarn of the outer layer of the fabric, due to its physical features contribute more to the large crimping each of the strands and greater compactness of the rope, which increases the effect simultaneous operation of the power elements. This circumstance increases the utilization rate from 0.5 to 0.8 and allows you to grow the maximum loads on the rope from 150 to 400 thousand Dan.

When you load the curved base of woven layer is rectified, resulting in bending of the weft threads relative to the base, causes the reduction of the diameter of the woven layer and the additional crimping force elements inside the case.

Thus the outer is about they are in it power load-carrying elements. Thus, the fact that changes phase structure (3 7-8) tissue under load, allowed not only to increase the number of strength elements (base participates in the load), but to get high quality racing in the seal-bearing elements. It is possible to increase the utilization rate from 0.5 to 0.8.

ROPE, containing situated in an outer protective sheath of synthetic strands, each of which is made in the form of a group of modules that represent bundles of filament yarn, twisted yarn, characterized in that, to increase strength and durability, it has more shells surrounding each group of modules corresponding strands, while the outer protective shell and the additional sheath is made in the form of woven covers, the warp threads are parallel to the axis of the rope, and the modules and strands are also parallel to the axis of the rope.
