Description

Annular hoisting belt with weft binding

Technical Field

The utility model relates to a jack-up hoist and mount field especially relates to an annular hoisting belt.

Background

The soft rigging is made up by using fibre filament yarn and making it into the form of band, rope or directly using fibre bundle to wind into ring form, and said rigging has the characteristics of light weight, soft texture, corrosion-resisting and corrosion-resisting property, easy storage and easy maintenance, and is popular in the field of hoisting and hoisting.

The types of soft rigging are various, and especially the annular soft rope is common. The annular soft rope, also known as annular hoisting belt, adopts winding equipment to make, and winding equipment includes the motor, by motor drive's action wheel and follow driving wheel, and its production process is: firstly, a bundle of fiber yarns consisting of a plurality of fiber bundles passes through the sheath, is sleeved on the driving wheel and the driven wheel to be tensioned, the winding equipment is started, the motor drives the driving wheel to rotate to drive the annular fiber bundles to rotate, after the annular fiber bundles are wound for a certain number of circles, the sheath is pulled open, and the two ends are sewn, so that the annular hoisting belt is manufactured. Generally, the number of filament bundle winding turns is dozens of turns, and for a large-tonnage annular cable with the weight of more than 5 tons, the number of filament bundle winding turns needs to reach hundreds of turns or hundreds of turns. In theory, the annular hoisting belt produced by the process and the equipment has the advantages that each wire is parallel to each other, is uniformly stressed and can bear the maximum breaking tensile load, but the process and the equipment are not the same. Firstly, when the filament bundle is wound, even if the tension of the filament bundle is very uniform, the filament bundle is wound on two rollers layer by layer, the length of the filament bundle wound in each circle is inconsistent, and the outer circle is long. Even if the winding length of each tow is theoretically ensured to be consistent without error, the tows of each tow move and are overlapped with each other in actual use, and the overall breaking tension is not ideal. Secondly, on the winding equipment, the rotation of the tows is driven by a driving wheel, the driving force directly acts on partial tows on the bottom layer, and other tows rotate by the friction force among the tows and are bound to generate the phenomenon of play, so that the length of the wound tows is changed. In a word, the annular hoisting belt is limited by the structure and the manufacturing process, the condition that partial tows are not stressed appears, the material utilization rate is reduced, the cost is increased, and the tow utilization rate is lower and lower along with the increase of the tonnage of the annular hoisting belt.
