Magnetic eraser special for steel wire rope

Abstract

The invention relates to a magnetic eraser special for a steel wire rope. The magnetic eraser comprises a shell, side plates, support rods, a residual magnetic intensity detection device, a magnetic erasion coil and a lining, wherein the shell at the top is shaped as a step, arch via holes are formed in the shell at the two sides, and the shell at the top and the shell at the two sides are orthogonally and fixedly connected; the side plates are arranged at the other two ends of the shell at the top; the support rods are arranged in the shell at the two sides and are orthogonally and fixedly connected with the side plates; the residual magnetic intensity detection device is arranged in a convex part of the shell at the top; the magnetic erasion coil is arranged in the shell and provided with an U-shaped iron core and a coil wound by an enameled wire, and the U-shaped iron core penetrates through the coil wound by the enameled wire; and the lining is arranged under the magnetic erasion coil. By the magnetic eraser special for the steel wire rope, residual magnetism of the detected steel wire rope can be effectively eliminated, and the influence of the residual magnetism of the steel wire rope on device control is avoided.

Description

Technical field [0001] The invention relates to a steel wire rope detection device, and mainly relates to a special degausser for steel wire rope that can eliminate the remanence of the steel wire rope. Background technique [0002] Wire rope refers to a flexible rope twisted with multiple or strands of thin steel wires. The wire rope is a rope twisted into strands from multiple layers of steel wires, and then a certain number of strands are twisted into a spiral with the core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying. The steel wire rope has high strength, light weight, stable work, not easy to be broken suddenly, and reliable work. [0003] At present, steel wire ropes are used in many fields such as mine hoisting and elevators. Because the steel wire rope is made of multiple steel wires, it is difficult to find the broken wires and corrosion inside. The wire rope non-destructive tester is the main testing instrumen...

AI Technical Summary

Problems solved by technology

The wire rope non-destructive testing instrument is the main testing instrument for detecting broken wires and corrosion inside the steel wire rope. However, the steel wire rope non-destructive testing instrument adopts the principle of magnetic detection, and the tested steel wire rope will have residual magnetism, which will make the equipment magnetic The switch malfunctions
