Description
Technical Field
The utility model relates to the technical field of nondestructive testing of steel wire ropes, in particular to excitation and detection technology for detecting damage of steel wire ropes by an electromagnetic method.
Background
The steel wire rope is a key component of important equipment related to life and production safety of hoisting machinery, elevators and the like, and has irreplaceable unique functions in the processes of lifting, bearing, traction, tensioning and the like. The safe use of the steel wire rope has important social and economic benefits. The nondestructive testing research of the steel wire rope has important significance for the safe use of the steel wire rope and the avoidance of huge economic waste.
The nondestructive testing method of the steel wire rope is various, and comprises an ultrasonic testing method, a ray testing method, an acoustic emission testing method, an eddy current testing method, an electromagnetic testing method, a mechanical testing method, an acoustic testing method, a current testing method, an optical testing method, a vibration testing method and the like which are commonly used in nondestructive testing. Until recently, electromagnetic detection has been one of the most practical detection methods currently accepted.
According to the working principle of electromagnetic detection method, its magnetization modes are classified into AC magnetization, DC magnetization and permanent magnetic magnetization. The AC magnetization detection precision is low, and the sensor is easy to generate heat and is troublesome to operate; the DC magnetization has the advantage of adjustable excitation intensity, but the equipment has larger weight and complex structure, and the matched DC power supply equipment is also needed to be provided during the working. Due to the limitations of both, these two approaches have been phased out in recent years. The permanent magnet magnetization detection device has the advantages of small volume, light weight, convenient use and low detection cost, and particularly the development and application of novel permanent magnet materials in recent years make the advantages of the novel permanent magnet materials more obvious, so that a large number of permanent magnet magnetization modes are used in a magnetic detection method.
According to the difference of signal acquisition positions and modes of an electromagnetic detection method, the detection modes at the current stage mainly comprise strong magnetic detection and weak magnetic detection, which are applied to the existing electromagnetic steel wire rope flaw detector and have thousands of times, but the weak magnetic detection and the strong magnetic detection both occupy a great part of weight on an excitation device, such as an utility model patent steel wire rope flaw detector (CN 210834761U) and an utility model patent steel wire rope flaw detector (CN 202837240U). In addition, for the strong magnetic detection technology, a strong permanent magnet is often adopted to excite the steel wire rope to a supersaturated state, and the magnetic field intensity of the permanent magnet is in a surplus state in most cases.
Most of the current steel wire rope flaw detection instruments detect single axial signals or radial signals, and if the two signals are switched, the inner support structure is redesigned or a new flaw detector is newly processed, so that the detection is extremely inconvenient.
Disclosure of Invention
In view of the above, the utility model provides a semi-excitation semi-detection type steel wire rope flaw detector, which not only fundamentally avoids the reaction force caused by mutual exclusion of magnetic poles through a semi-side excitation device, but also can process the output signal of a Hall element nearby, thereby reducing the external interference in the signal transmission process, and simultaneously, the self weight is greatly reduced due to the elimination of a side excitation device, and further light weight and convenience are realized.
According to the utility model, the NdFeB permanent magnet with the model N48 is adopted, and the main magnetic flux direction is radial, so that a stronger magnetic field passes through the inside of the steel wire rope. By means of the permanent magnet, the steel wire rope and the transitional armature structure, a complete magnetic path is realized inside the instrument. The neodymium-iron-boron permanent magnet can quickly magnetize the dynamically operated steel wire rope and is not influenced by the speed of the steel wire rope.
The utility model adopts the plastic outer shell and the plastic inner supporting sleeve, thereby not only reducing the weight of the instrument, but also ensuring that other hybrid magnetic circuits are not arranged in the flaw detector except for the permanent magnet, the steel wire rope and the transitional armature structure, and effectively avoiding the waste of magnetic fields.
The Hall element placement unit designed by the utility model can be suitable for various collection modes. The Hall element is a main sensor for collecting magnetic leakage signals, and can convert the change of the leakage quantity of the magnetic path caused by the damage of the steel wire rope into corresponding voltage change, and reversely diagnose the damage of the steel wire rope by means of the voltage change.
The detachable annular positioning sleeve capable of being embedded into the Hall element placing unit can effectively position the Hall element and the replaceable lining, is composed of four parts, and is provided with positioning and supporting devices which are matched with each other, so that the sensor is prevented from being damaged due to improper installation positions in the installation process.
The upper shell designed by the utility model can contain other processing units such as amplification, filtering, difference and the like of Hall element signals, processed data can be displayed in a display screen at one side in real time, and a switch operation panel with related functions is arranged beside the display screen.
