Description

Steel wire rope joint-free loop rope core

Technical Field

The invention relates to the field of metal products, in particular to a technology for manufacturing a steel wire rope jointless rope ring.

Background

The steel wire rope jointless rope ring (hereinafter referred to as a rope ring) is particularly manufactured by winding the same steel wire rope, namely, one end of the steel wire rope is folded back, the steel wire rope is bound with the original steel wire rope and is wound into a circle (rope core), the other end of the steel wire rope is inserted and wound on the circle, and the steel wire rope is wound for six circles to manufacture the steel wire rope rigging.

After the rope loop is wound, the exposed end of the steel wire rope needs to be inserted into the position of the rope core, the original rope core needs to be replaced, the process is called as core replacement, and the length of the core replacement is about half of the circumference of the rope loop (the process is suitable for a small rope loop which can be wound in a hand). In actual production, however, in order to adapt to large-scale production, a complete substitute cord is often adopted, and after winding is completed, the cord ends at two ends are respectively pressed in, so that the substitute cord is completely replaced.

At present, the popular rope cores are mainly 2 types, one type is to use a certain fixed-length steel pipe (mostly made of steel materials) to be wound into a circle, to wind a steel wire rope outside the steel pipe, then to plug the two ends of the steel wire rope into six circles of core parts respectively along the gap of a rope strand, to replace the steel pipe, and the process of replacing the core is the most original method (the steel pipe after replacing the core is scrapped under the common condition). When the steel pipe is selected, the diameter of the steel pipe is generally 1.12 times larger than that of the rope.

The other is that a steel wire rope with the diameter similar to that of the steel pipe is used to replace the steel pipe, and the rope core is mainly suitable for a rope ring made on machine equipment, and in order to enable the rope core to rotate on a driving wheel of the equipment, a flexible steel wire rope is adopted. However, the steel wire rope has three major disadvantages, namely, the rigidity of the rope core is insufficient. No matter how much tension is applied to the steel wire rope core, when the steel wire rope is wound around the steel wire rope core, the twisting force of the steel wire rope and the steel wire rope core can interact, so that the steel wire rope core rotates at an initial winding section, and the twisting angle of the steel wire rope on the steel wire rope core is locally reduced along with the gradual change of the increase of the winding length, thereby influencing the subsequent production and the product quality of a rope ring; moreover, when the second circle and the third circle are wound, the rope core is changed again; and secondly, the rope core made of the steel wire rope has high cost. When the wire rope core is used, untwisting and loosening are carried out, so that the wire rope core can be used for only two times and must be scrapped; on the other hand, the method cannot be used universally when producing the rope loops with the same diameter and different lengths, and the middle butt joint is time-consuming and troublesome; thirdly, the diameter of the connecting joint is too large, so that the rotating and winding effects on the driving wheel are influenced, and the workload of subsequent rope repair (correction to make the lay length uniform) is increased.

A steel wire rope jointless rope loop is a hoisting rigging mainly used for large-tonnage hoisting, such as offshore assembly of a petroleum jacket and the like, has the characteristics of large hoisting tonnage and convenient use, has production yield of a considerable scale since being introduced into China, and discloses a rope core manufacturing method and a rope core using method newly developed by our company for mutual study in order to reduce material waste and manpower resource waste and reduce labor intensity. The specific contents are as follows:

disclosure of Invention

The invention relates to a loop rope core of a steel wire rope without a joint, which is composed of 1-3 locking joints, a plurality of connecting joints and a plurality of pins, wherein: one end of each locking section is an opening section, the other end of each locking section is a socket section, and a concave connecting section is arranged between the opening section and the socket section; one end of each connecting joint is an opening section, and the other end of each connecting joint is a socket section; the opening section and the socket section are respectively provided with a first pin hole and a second pin hole, the socket section of one connecting joint or locking joint is inserted into the opening section of the other connecting joint or locking joint, so that the first pin hole of the socket section of one connecting joint or locking joint is aligned with the second pin hole of the opening section of the other connecting joint or locking joint, a pin passes through the first pin hole and the second pin hole, two connecting joints or two locking joints or one connecting joint and one locking joint are connected together, and by analogy, a plurality of connecting joints and 1-3 locking joints are connected into a rope ring rope core.

The invention relates to a loop rope core of a steel wire rope without joints, wherein: it still includes: rope card, the rope card includes: collet, U type ring and nut, the rope card dress is on the spill linkage segment of locking section, and the bottom cover in the U type ring is on the spill linkage segment, and two tip of U type ring are passed respectively and are opened on two holes of collet, and wire rope passes between collet and the spill linkage segment, and U type ring tip is through the nut respectively with wire rope card between collet and spill linkage segment.

The invention relates to a loop rope core of a steel wire rope without joints, wherein: the rope core of the rope loop is provided with 1-3 rope clamps.

The loop rope core of the steel wire rope without the joint has the following advantages:

1. the loop rope core without the joint of the steel wire rope overcomes the problem of local looseness caused by untwisting of the steel wire rope core, thereby improving the overall quality and the production efficiency.

2. Pressing the connected joints with aluminium tubes affects the running and thus the quality when passing over the driving wheels. The rope clip solves the problem to the maximum extent.

3. More economical, efficient and more convenient to use. The rope core can be repeatedly used for many times and can be conveniently connected. The steel wire rope core connection needs pressing, and the rope ring rope cores with different lengths are also independently manufactured and can not be repeatedly used; when the steel pipe is wound with the rope loops with different lengths, the steel pipe cannot be repeatedly utilized, and the production efficiency is lower.
