Abstract

A steel wire rope with an oversized diameter and a plastic-coated compacted strand of a metal core sequentially comprises a metal rope core (1), plastic (2) and an outer strand (3) from inside to outside; the structure is formed by twisting six outer layer strands (3) around a plastic-coated metal rope core (1); the plastic (2) is filled between the outer layer strand (3) and the metal rope core (1), the structure of the outer layer strand (3) is 52WS, the structure of the metal rope core (1) is 6X19S, and the structure of the central strand of the metal rope core (1) is 1X 19S. The invention solves the technical problem of producing the oversized diameter metal core plastic-coated compacted strand steel wire rope with the diameter of more than 100mm, and can meet the requirements of compacted strand steel wire ropes for equipment such as large-scale hoisting, ships, offshore facilities, hoisting and transportation and the like.

Description

Super large diameter metal core plastic-coated compacted strand wire rope

Technical Field

The invention relates to an oversized-diameter metal core plastic-coated compacted strand steel wire rope, and belongs to the technical field of metal products.

Background

The requirement of the compacted strand steel wire rope on production tooling equipment is high, and the maximum diameter of the six-strand compacted strand steel wire rope is 130mm according to the standard of ' coarse diameter steel wire rope ' GB/T20067-2017 of the people's republic of China. But the difficulty is very great for producing the metal rope core plastic-coated compacted strand steel wire rope with the diameter of more than 100 mm. With the continuous development of social economy and the continuous change of the use condition of the steel wire rope, the product localization market is also deepened continuously, and the existing compacted strand steel wire rope cannot meet the use requirements of equipment such as large-scale hoisting, ships, offshore facilities, hoisting and transportation and the like.

Disclosure of Invention

The invention aims to solve the technical problem of production of the oversized-diameter metal core plastic-coated compacted strand steel wire rope with the diameter of more than 100mm, improve the breaking force of the steel wire rope, prolong the service life of the steel wire rope and meet the requirements of compacted strand steel wire ropes for equipment such as large-scale hoisting, ships, offshore facilities, hoisting and transportation.

A steel wire rope with an oversized diameter and a plastic-coated compacted strand of a metal core sequentially comprises the metal core, plastic and an outer strand from inside to outside; the structure is formed by twisting six outer layer strands around a plastic-coated metal rope core; plastics are filled between outer layer strand and the metal cord core, and outer layer strand structure is 52WS, and the metal cord core structure is 6X19S, and the central thigh structure of metal cord core is 1X 19S.

Adopt above-mentioned technical scheme's beneficial effect:

1. the invention solves the technical problem of producing the oversized diameter metal core plastic-coated compacted strand steel wire rope with the diameter of more than 100mm, and can meet the requirements of compacted strand steel wire ropes for equipment such as large-scale hoisting, ships, offshore facilities, hoisting and transportation and the like.

2. Compared with the common compacted strand steel wire rope, the metal core plastic-coated six-strand steel wire rope has the advantages of relatively more stable structure and higher bearing breaking tension.

Drawings

Fig. 1 is a schematic cross-sectional structure of the present invention.

In the figure: 1-metal rope core, 2-plastic and 3-outer layer strand.

Detailed Description

The oversized-diameter metal core plastic-coated compacted strand steel wire rope is further described in detail with reference to the accompanying drawings as follows:

as shown in figure 1, the oversized-diameter metal core plastic-coated compacted strand steel wire rope sequentially comprises a metal rope core 1, plastic 2 and an outer layer strand 3 from inside to outside; the structure is formed by twisting six outer layer strands 3 around a plastic-coated metal rope core 1; the plastic 2 is filled between the outer layer strand 3 and the metal rope core 1, the structure of the outer layer strand 3 is 52WS, the structure of the metal rope core 1 is 6X19S, and the structure of the central strand of the metal rope core 1 is 1X 19S.

The invention solves the technical problem of producing the oversized diameter metal core plastic-coated compacted strand steel wire rope with the diameter of more than 100mm, and can meet the requirements of compacted strand steel wire ropes for equipment such as large-scale hoisting, ships, offshore facilities, hoisting and transportation and the like.
