Abstract

Construction of a two-layer steel balancing rope with a sisal insert. In contrast to the existing multi-strand ropes of circular cross-section, in which two or three layers of round or flat tubeless strands are wound onto a sisal insert, the solution introduces the production of a rope in which there are six round strands wound uniformly on the left on a sisal insert and a layer of eight flat strands formed by a core (core) and two layers of wires is wound uniformly on them uniformly on the right. Since the designed flat strands are compact and rigid, it is ensured that the possibility of the rope spinning and the formation of deformation is prevented at significantly balanced torques, which significantly increases the service life of the rope.

Description

(54) Steel leveling rope

Two-layer steel leveling rope construction with sisal insert. In contrast to the existing circular cross-sectional strands where two or three layers of round or flat tubeless strands are wound onto a sisal insert, the solution introduces the production of a rope in which six round strands are wound DC on the sisal insert and wound DC. a layer of eight flat strands consisting of a core (soul) and two layers of wires. Since the designed flat strands are compact and rigid, the rope can not spin and become deformed at greatly balanced torques, thereby significantly increasing the rope's service life.

The invention relates to a steel leveling rope.

Until now, multi-spoke steel balancing ropes of circular cross-section have been used for underground mining equipment. In ropes of this type, two or three layers of circular or flat tubeless strands are wound onto the sisal pad. The disadvantage of these ropes is their susceptibility to deformation, which is manifested by cutting out individual strands or the whole layer of strands from the rope cross-section. The operation of such deformed ropes is unreliable and the ropes must be set aside so their service life is low.

These drawbacks are overcome by the steel leveling rope according to the invention. Its essence is that on six circular strands wound DC on the sisal insert, a layer of eight flat strands consisting of a core (core and two layers of wires) is wound DC. This achieves greatly balanced torques, prevents the rope from twisting and creating deformations, since the designed flat strands of the outer layer are compact and rigid. The same stress and load of all strands and wires is achieved throughout the use of the rope, thereby significantly increasing its life.

An exemplary embodiment of a steel alignment rope according to the invention is shown in the accompanying drawing, in which a schematic cross-section of a two-layer steel alignment rope with a sisal insert is shown schematically. The inner layer on the sisal insert 1 has six strands of circular 2 wound DC 1 + 6 + 12 wires. The outer layer is made up of eight flat strands 2 wound DC on the right, construction - core + 2 layers of wires (J + 12 + 16 or J + 8 + 16? J + 8 + 14) J + 9 + 15).

The steel balancing rope according to the invention, manufactured in particular for individual diameters from 37.5 to 67.0 mm, is suitable for static and dynamic loading on deep mining equipment, where the distance between the suspensions is more than 25 times the diameter of the rope. Ensures reliable operation with a significantly longer lifetime compared to existing multi-strand ropes of circular cross-section.
