Description

Technical field [0001] The invention relates to the field of steel wire rope testing, in particular to a steel wire rope cleaning, testing and maintenance equipment, which is used for steel wire rope torsion release, cleaning and descaling, non-destructive testing and oil immersion maintenance. Background technique [0002] In the construction of transmission line conductors, wire ropes are often used. Due to the torsion of the wire itself, with the increase in the number of times of use, the torsion of the wire to the wire rope will accumulate, and the accumulated torsion cannot be released. The wire rope bends, the load is reduced, and the wire rope is finally broken. For this reason, the storage and distribution departments of tools and instruments need to perform wire rope pay-off inspections frequently, and the torsion of the wire ropes needs to be released during the pay-off test; the current method of releasing the wire rope torsion Most of them use cranes or forklifts to ...

Problems solved by technology

[0002] In the construction of power transmission line conductor deployment, steel wire ropes are often used. Due to the torsion of the wire itself, as the number of uses of the wire rope increases, the torsion transmitted from the wire to the wire rope will accumulate and increase, and the accumulated torsion cannot be released. The wire rope is bent, the load is reduced, and the wire rope is eventually broken. For this reason, the tool storage and distribution department needs to carry out wire rope release inspection frequently. During the wire rope inspection, the wire rope torque needs to be released; the current method of wire rope torque release , most of them use cranes or forklifts to release the internal force by means of suspension. The working method is complex, heavy, and the work efficiency is low, and there are still great safety hazards in the operation.

[0003] During the long-term use of the steel wire rope, the oil on the surface of the steel wire rope is easily eroded by the environment and adheres to a lot of sand and dust, which affects the service life of the steel wire rope; the traditional manual treatment method is labor-intensive and low-efficiency in cleaning the surface of the steel wire rope. Unsatisfactory cleaning effect

[0004] Steel wire ropes are prone to defects such as broken wires, wear, corrosion, local properties, and journal thinning during use, resulting in a decrease in the strength of the steel wire rope or even failure, which is likely to cause accidents; the most widely used and popular methods for non-destructive testing of steel wire ropes are divided into There are two categories of visual inspection and electromagnetic inspection. Visual inspection is the simplest, most reliable, and most traditional inspection method, but this method has great limitations; wire rope electromagnetic inspection is currently the most mature, most widely used, and the most widely used inspection method is The LF (local damage) detection method and the LMA (metal cross-sectional area loss) detection method, these two detection methods use the magnetic flux leakage detection principle and the main magnetic flux detection principle in electromagnetism. Apply a strong constant magnetic field to saturate the wire rope magnetization, detect the local damage (LF) of the wire rope through the magnetic field leaked at the damaged part of the wire rope, and detect the metal cross-sectional area of ​​the wire rope by measuring the magnetic flux passing through the inside of the wire rope These two methods detect different types of damage to steel wire ropes. Local damage mainly detects broken wires, deformation, corrosion pits, etc. Metal cross-sectional area loss (LMA) mainly detects wear and corrosion and wide fracture broken wires.
