Device for detecting steel tie rod or inhaul cable and application

Abstract

The invention provides a device for detecting a steel tie rod or an inhaul cable and application. A rod section detection mechanism which can stretch and retract relative to a fixing frame is installed in the fixing frame. Sensors are evenly installed in the plane, in the same vertical axis direction as an outer fixing ring, of the inner wall of an inner fixing ring. A lug base detection mechanism used for detecting a lug base of the detected steel tie rod or inhaul cable is installed on the fixing frame. The device is used for detecting the application of the steel tie rod or the inhaul cable through a metal magnetic memory detecting method. The inner diameter of a detection cavity can be adjusted immediately according to the diameter changes of the detected steel tie rod or the inhaul cable, and the adaptability is good. A detection gap produced by reducing when the outer fixing ring is expanded can be filled in time, and therefore a reducing detection ring is a complete detection ring both before and after reducing; due to the fact that the sensors are evenly distributed, comprehensive detection can be achieved, and the detection accuracy is greatly improved. The rod section of the detected steel tie rod or inhaul cable is detected, and meanwhile the lug base of the detected steel tie rod or inhaul cable is comprehensively detected.

Description

technical field [0001] The invention belongs to the field of construction engineering, and mainly relates to the detection of steel rods or cables, in particular to a device and application for detecting steel rods or cables. Background technique [0002] Steel tie rods or cables are tension members assembled from rods and connectors. They have the advantages of strong wind load resistance, good toughness, and long fatigue life, so they are widely used in stadiums, airports, stations, roads and bridges, etc. field. However, the steel tie rods or cables, especially the ends, are also subjected to other actions such as bending moments and shear forces in actual engineering. Therefore, the steel tie rods or cables are prone to stress concentration, hidden damage or even obvious cracks at the above positions, which is serious. Threat to the security of the structure in which it is located. In recent years, many safety accidents caused by the failure of steel tie rods or cables...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, this application provides a device and application for detecting steel rods or cables, which solves the problem that steel rods or cables cannot be monitored in real time in the prior art, and solves the problem of magnetic memory detection of steel in the prior art. In the process of pulling the rod or cable, the accurate normal component and tangential component of the magnetic memory cannot be obtained, so that the problem of accurate detection cannot be achieved
