Device and method for detecting parallel drag steel wire slings

Abstract

The invention provides a device and a method for detecting parallel drag steel wire slings. The device comprise sensors, magnetic field equipment, amplification and filter equipment, a signal transceiver and a computer. The sensors can be mounted on drag slings and are used for transmitting test signals and receiving test reflection signals; the magnetic field equipment is used for supplementing magnetic fields for the sensors; the amplification and filter equipment is in communication connection with the sensors and is used for amplifying signal power for the transmitted test signals and thereceived test reflection signals and removing noise waves by means of filter; the signal transceiver is in communication connection with the amplification and filter equipment and is used for transmitting excitation signals and receiving echo signals; the computer is in communication connection with the signal transceiver and is used for stimulating excitation signal instructions and carrying outanalysis and oscillography on the received echo signals so as to obtain test parameters. According to the scheme, the device and the method have the advantages that the internal defect locations and defect levels of the parallel drag steel wire slings can be quickly and nondestructively detected by the aid of the device and the method, the detection efficiency can be effectively improved, and thedetection difficulty can be lowered.

Description

technical field [0001] The invention belongs to the technical field of wire-drawn sling detection, and in particular relates to a parallel wire-drawn sling detection device and method. Background technique [0002] Stayed cables or slings are the main load-bearing components of large-scale structural bridges, and their health directly affects the safety of the bridge. Judging from past bridge construction and management and maintenance experience, many cable-stayed bridges have problems such as broken cable wires or steel corrosion during construction or use. If the disease continues to develop, it will inevitably affect the operation safety of the bridge structure. However, at present, there is no fast and comprehensive technical means and equipment for bridge stay cables, which greatly restricts the safety evaluation cost of bridge structures. It took more than 10 years to change the cable for a long time. [0003] At present, the preliminary analysis of the research on ...
