Precise troubleshooting device for slip rope magnetic flux leakage detection fault region

Abstract

The invention discloses a precise troubleshooting device for a slip rope magnetic flux leakage detection fault region. The precise troubleshooting device comprises a mounting plate, wherein a pair ofpulley assemblies is arranged on the mounting plate, wire pressing clamps are mounted at the head and the tail of each pulley assembly, and the bottom parts of the pulley assemblies are matched with the mounting plate by means of guide rails; a motor is arranged on the mounting plate, the motor is connected with magnetic flux leakage detection equipment by means of a towing line cable, and a sliding speed adjusting device is mounted at the lower part of the mounting plate; when the magnetic flux leakage detection equipment detects magnetic flux leakage, the sliding speed adjusting device operates to make a slip rope magnetic flux leakage detection device stop near a fault point of slip rope steel cables to be detected; and the motor executes a forward and reverse rotation command to make the magnetic flux leakage detection equipment connected with the other end of the towing line cable repeatedly detect around the fault point, so that precise troubleshooting of the fault region is completed. The precise troubleshooting device reduces the manpower maintenance cost, lowers the labor intensity, can perform safety assessment, fault positioning and data acquisition on the steel cable ofslip rope equipment, and can carry out self-adaptive speed regulation parking of the detection device near the fault point.

Description

technical field [0001] The invention relates to an accurate troubleshooting device for a sliding cable magnetic flux leakage detection fault area, which is applied to the detection of sliding rope steel cable equipment, and further implements online precise troubleshooting for a series of potential risks such as steel cable wear, corrosion, and broken wires. Background technique [0002] After the steel cable equipment has been in service for a long time, the strands of the steel cable will be worn, broken, and corroded due to natural or man-made reasons, and there are potential safety hazards. The early detection of hidden dangers mainly depends on the non-destructive testing technology of steel cables. [0003] The non-destructive testing of steel cables is a non-destructive testing method based on the principle of magnetic flux leakage. The normal leakage magnetic field between steel cable strands is a regular and periodically distributed spatial field. When problems such ...

[0002] After the steel cable equipment has been in service for a long time, the strands of the steel cable will be worn, broken, and corroded due to natural or artificial reasons, and there are potential safety hazards. The early detection of hidden dangers mainly depends on the non-destructive testing technology of steel cables

[0003] The non-destructive testing of steel cables is a non-destructive testing method based on the principle of magnetic flux leakage. The normal leakage magnetic field between steel cable strands is a regular and periodically distributed spatial field. When problems such as broken wires, wear, and corrosion occur locally, the The irregular signal corresponding to the problem, the local fault of the steel cable will make the long-term stress uneven when the zipline is in use, and it is easy to cause the situation that the local point length is widened to both sides
