Embodiment Construction

[0035] figure 1 As shown, the specific implementation is as follows:

[0036] A portable wire rope damage detection device, comprising a housing 2 composed of a fixed housing 201 and two movable housings 202, an excitation shielding unit 11, a detection induction unit 10 for inductively processing the magnetic signal of the excitation shielding unit 11, and a stroke calculation unit 8 1. The guide holding unit 4 used to control the direction of travel of the detection device and the hand-held instrument 12 with a built-in power supply. The two movable shells 202 are arranged on the same side of the fixed shell 201, and one side of the two movable shells 202 is oppositely arranged, and the other The sides are respectively connected with the two sides of the fixed shell 201 through the hinge 3, and the two movable shells 202 are provided with a locking mechanism 9 that restricts their rotation around the hinge 3, and the two movable shells 202 rotate until they fit the fixed she...

Abstract

The invention relates to a portable flaw detection device for a steel wire rope. The device comprises a housing consisting of a fixed shell and two movable shells, an excitation shielding unit, a detection induction unit for inducing magnetic signals of the excitation shielding unit, a stroke computing unit, a guide maintaining unit for controlling the advancing direction of the detection device and a portable instrument which is internally provided with a power supply. The device provided by the invention is novel and practical in structure, convenient to carry manually and simple to install and operate; synchronous flaw detection in once mounting can be realized, and disassembly and conversion are not needed; the signal to noise ratio in detection is effectively improved by means of an advanced and reliable magnetic shielding anti-jamming technique; the repeatability and the stability of flaw detection results are good, the detection precision is remarkably enhanced, and the misjudgment rate of flaws is greatly reduced.

Description

technical field [0001] The invention relates to an all-magnetic information induction device, in particular to a portable wire rope damage detection device. Background technique [0002] During the actual use and operation of the steel wire rope, it must be subjected to pure mechanical effects such as bending, stretching, and torsion to cause fatigue. Severe fatigue leads to the fracture of the metal structure, resulting in a large number of broken wires, broken strands, and even instantaneous breakage of the whole rope. This type of problem brings great hidden dangers to the safe operation of hoisting equipment, which may lead to major casualties. [0003] Nowadays, the non-destructive testing techniques for steel wire and cable mainly include strong magnetic testing, weak magnetic testing and ultrasonic testing, but there are obvious technical or application defects. [0004] The strong magnetic inspection has the following defects: [0005] 1. The ability to detect th...
