Embodiment 1

[0031] see figure 1 , in an embodiment of the present invention, a steel wire cable with reinforced steel wire prestressing includes a cable body, and the cable body is composed of a compacted strand 1, a sleeve assembly and a sealing strand; the center of the cable body is provided with a The compacted strand 1 bearing the axial force, the outer edge of the compacted strand 1 located in the center of the cable body is covered with the first sleeve 2 for keeping the inside tight, specifically, the compacted strand 1 includes a main wire 11 , gap-filling wire 12 and covering wire 13, wherein the main wire 11 is positioned at the central position of the compacted strand 1, and the outer edge of the main wire 11 is equidistantly arranged with the covering wire 13, and the covering wire 13 and the main wire 11 There are interstitial wires 12 for filling the gap between the two, and the first sleeve 2 is coated on the outer edge of the covering wire 13. It should be noted that the ...

Embodiment 2

[0036] In another embodiment of the present invention, there is also provided a method for manufacturing a steel wire cable for reinforcing steel wire prestress, comprising the following steps:

[0037] Step 1, prefabricating the compacted strands, determining the diameter of the compacted strands according to the diameter of the prepared cables, wherein the diameter of the compacted strands should be less than a quarter of the diameter of the cables, and selecting materials for the components in the compacted strands, specifically Say, the selection consists of the following parts:

[0038] S1, main wire selection, select the steel wire processed from carbon steel wire as the main wire, and cut the length;

[0039] S2, material selection for the gap filler wire, choose aluminum wire as the gap filler wire, and cut the length to make it consistent with the length of the main wire;

[0040] S3, material selection of covering wire, choose chromium-molybdenum low-alloy wire as t...

Abstract

The invention discloses a steel wire cable for strengthening steel wire prestress and a manufacturing method of the steel wire cable and particularly relates to a steel cable for improving the yield strength, the elongation and the straightening property. A compacted strand used for bearing axial stress is arranged in the center of a cable body, the outer edge of the compacted strand located in the center of the cable body is coated with a first casing pipe used for keeping inside compacted; a levorotary airtight strand used for strengthening prestress of an inner ring is arranged in the circumference of the outer edge of the first casing pipe and is formed by spirally winding and attaching multiple prestress steel wires and tightly attaching the prestress steel wires to the surface of thefirst casing pipe; multiple compacted strands used for improving the overall rigidity of the cable body are arranged in the circumference of an outer ring of the levorotary airtight strand, and the outer edges of the compacted strands distributed on the outer ring of the levorotary airtight strand are covered with a second casing pipe; a dextrorotatory airtight strand used for strengthening the prestress of the outer ring is arranged in the circumference of the outer edge of the second casing pipe and is formed by spirally winding and attaching multiple prestress steel wires and tightly attaching the prestress steel wires to the surface of the second casing pipe.

Description

technical field [0001] The invention relates to the field of steel cables, in particular to a steel wire cable for reinforcing steel wire prestress and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development of my country's construction industry, lifting equipment is very popular in the market. Most of the lifting equipment realizes the lifting and transportation of heavy objects through cables. Among strands, prestressed steel cables are most frequently used. [0003] Prestressed steel wire, which is made of high-quality high-carbon steel round wire rod after austempering and drawing, is the most commonly used steel strand variety in China at present. However, the service life of the prestressed steel cables on the market is not long, mainly because they still need to be improved in terms of yield strength, elongation and straightness. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned...
