Abstract

An eighteen-strand non-twist braided rope is a braided rope with an orthohexagonal cross-section, which is knitted crossly by nine left-lay strand ropes with circular cross-sections and nine right-lay strand ropes with circular cross-sections according to the rule that the left-lay strand ropes turns right and the right-lay strand ropes turns left. Because the absolute value of the torque sum of the nine left-lay strand ropes is equal to the absolute value of the torque sum of the nine right-lay strand ropes, the synthesized torques of the eighteen strand ropes offset mutually at the axial center and become zero, which makes the eighteen strand ropes have the characteristic of no rotation under tensile forces and no twist without tensile forces. The utility model is suitable for hoisting machinery and construction traction equipment, and is also suitable for ropes for ships, ropes for binding heavies and so on.

Description

Eighteen strand non-twist plaited rope

The utility model belongs to rope tool class, is specifically related to the not improvement of turn-knob kernmantle of multiply.

Along with rapid economic development and scientific and technological progress, the application of kernmantle is increasingly extensive, and extremely the user welcomes, and departments such as industry, boats and ships have higher requirement to intensity, serviceability, the description of kernmantle.At present, the employed kernmantle kind of China is single, structure is also looser, and limitation is in use arranged, and can not satisfy the requirement of industrial department.

The purpose of this utility model provides a kind of high strength, and is applied widely, and do not rotate when having the tension force of being subjected to, and loses tension force or do not beat not turn-knob kernmantle of ten stereotyped writings turned round under free state, for the multiply kernmantle increases a kind of new designs and varieties.

The technical solution of the utility model is: according to the dextrorotation of left-hand lay strand, it is orthohexagonal kernmantle that the left-handed regular interlacing of right-laid strand becomes the cross section by the right-laid strand of the left-hand lay strand of 9 bursts of circular cross-sections and 9 bursts of circular cross-sections.

Description of drawings:

Fig. 1 is external form figure of the present utility model;

Fig. 2 is a schematic cross-section of the present utility model.

Fig. 1-2 has provided an embodiment of the present utility model: the left-hand lay strand of 9 bursts of circular cross-sections is divided into three groups, the right-laid strand of every group of 3 strands, 9 bursts circular cross-sections also is divided into three groups, every group 3 strands, each organizes strand by the dextrorotation of left-hand lay strand, and it is orthohexagonal kernmantle that the left-handed regular interlacing of right-laid strand forms the cross section.Described circular cross-section strand can be steel wire rope, nylon rope, the rope made of hemp.

In the utility model, because the absolute value from torque of each strand equates, the absolute value of the torque sum of 9 strands of left-hand lay ropes equates with the absolute value of the torque sum of 9 strands of right-laid strands, is zero thereby the synthetic torque that weaves back 18 strands of strands is cancelled out each other in its axle center.Do not rotate the characteristics of not twisting together when losing tension force when making it have the tension force of being subjected to.Nylon, the rope made of hemp that can be widely used in braidings such as the crane gear of occasions such as mine, boats and ships, harbour and power transmission and transformation line construction pulling equipment according to the steel wire rope of the utility model braiding can be used as Cable rope for ship, binding weight with restricting etc.

Claims

1, a kind of 18 strands of turn-knob kernmantles not, it is characterized in that it by the right-laid strand of the left-hand lay strand of 9 bursts of circular cross-sections and 9 bursts of circular cross-sections according to the dextrorotation of left-hand lay strand, it is orthohexagonal kernmantle that the left-handed regular interlacing of right-laid strand becomes the cross section.
