Method for manufacturing annular lifting belt with weft constraint

Abstract

The invention provides a method for manufacturing an annular lifting belt with weft constraint. The method comprises the steps that a fiber tow penetrates through a sheath in a laminated state, and sheaths a driving wheel and driven wheel of winding equipment, and tensioning is carried out; a threadlet tow winds round the fiber tow; the winding equipment is started, a motor of the winding equipment drives the driving wheel to rotate, the driving wheel rotates to drive the annular fiber tow to rotate, at the same time, a rotating device drives the threadlet tow to wind round the fiber tow to constrain the fiber tow and a multi-bundle annular loop is formed through rotation, and the production of a bearing core of the annular lifting belt is completed; after the threadlet tow winds a certain number of turns, the sheath is pulled apart, and the two ends of the annular loop are stitched to complete the production of the annular lifting belt. The method for manufacturing the annular lifting belt with the weft constraint has the advantages that the threadlet tow is used for constraining the fiber tow to prevent the fiber tow from loosening and being misplaced, which can improve the utilization of the tow, reduce the production cost, and improve the use stability of the produced annular lifting belt.

Description

technical field [0001] The invention relates to the field of hoisting and hoisting, in particular to a manufacturing method of an endless hoisting belt. Background technique [0002] Soft rigging refers to a kind of rigging made of fiber filaments, woven into ribbons, or braided into ropes, or directly wound into rings with tow. This kind of rigging has light weight, soft texture, durable Anti-corrosion, easy to store and easy to maintain, it is very popular in the field of lifting and hoisting. [0003] There are many types of soft slings, especially ring slings. Ring sling, also known as ring sling, is made of winding equipment. The winding equipment includes a motor, a driving wheel driven by the motor and a driven wheel. The production process is: first, a bundle of fiber filaments composed of several bundles of Go through the sheath, put it on the driving wheel and the driven wheel and tighten it, turn on the winding equipment, the motor drives the driving wheel to ro...

AI Technical Summary

Problems solved by technology

Even if it is assumed that the winding length of each tow is guaranteed to be the same in theory without error, but in actual use, the tows move and overlap each other, and the overall breaking force will not be ideal

Secondly, on the winding equipment, the rotation of the tow is driven by the driving wheel, and the driving force directly acts on the bottom part of the tow, and the other tows rely on the friction between the tows to rotate, which is bound to cause movement, resulting in the winding of the wound yarn. bundle length variation

In a word, the ring-shaped sling is restricted by the manufacturing process, and some tows are bound to be unstressed, the material utilization rate is reduced, and the cost is increased. Moreover, as the tonnage of the ring-shaped sling increases, the tow utilization rate will increase. Low
