Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Taking the connection of Φ2.46mm (thick end) / Φ1.63mm (thin end) variable-diameter steel cable as an example, the structural parameters of the cable used for steel cable connection are shown in Table 1.

[0027] Table 1 selects the structural parameters of the cable

[0028]

[0029] The specific connection method is as follows:

[0030] 1) if figure 1 As shown, the outer monofilament 3 in the connection area of ​​the Φ2.46mm / Φ1.63mm variable-diameter steel cable is loosely twisted and opened, the central monofilament 4 of the Φ2.46 end steel cable is left long, and the center monofilament 4 of the Φ1.63 end steel cable 5 Cut short, the outer monofilaments in the joint area of ​​the two steel cables are divided into 2 groups and cut short, deburring;

[0031] 2) if image 3 As shown, the diameter of the thin end / diameter of the thick end ...

Abstract

The invention relates to a composite connection method for a high-strength variable-diameter steel cable and aims to overcome the defects of complicated process, large strength loss, corrosiveness, large joint size, low flexibility and difficulty in winding of an existing high-strength variable-diameter steel cable connection method. A composite connection process method for strengthening equal-pitch plugging joints by using impregnated glass fiber strips / impregnated nylon fiber ropes is adopted. By single-wire equal-pitch grouped plugging, the strength loss of a steel cable junction is reduced; meanwhile, the plugging joints are wrapped, wound and tied in a sectional mode by using impregnated glass cloth / impregnated nylon ropes in a connection area, and the connection area can be strengthened and fixed after solidification to form a flexible composite joint of which the interior is twisted and wound by metal steel wires and the exterior is wrapped and reinforced by composite materials in a sectional mode. The composite connection method for the high-strength variable-diameter steel cable has the characteristics of high connection strength, reliable performance, small joint size, high flexibility and strong environment resistance.

Description

technical field [0001] The invention relates to a composite material connection method of variable-diameter steel cables, in particular to a high-strength flexible composite material connection method and a preparation process thereof. Background technique [0002] Variable-diameter high-strength steel cables have specific uses in many special occasions, especially in the towing of marine engineering ships and aviation vehicles. Due to the requirements of load bearing and service conditions, there are often special requirements for the connection of steel cables, such as: high strength, flexibility, and the size of the connection area is similar to the diameter of the steel cable. The existing high-strength variable-diameter steel cable connection is adopted abroad by first annealing the steel wire at the joint to reduce the rigidity and strength of the steel wire, and then twisting the steel wire at the joint butt. This steel cable connection method completely relies on th...
