There are several correct methods of wire rope detection
Wire rope detectionThere are several correct methods:
1. Inspection method
The wire rope inspector uses an oil caliper to measure its diameter. The measurement method is two outer diameters of the wire rope. The middle section should be a measuring point every 100m, and two measuring points should be measured 1m before and after respectively. Record the smaller diameter and compare it with the diameter measured by the new wire rope factory. Replace the measuring point every month to achieve monthly fixation and comparative analysis.
The measured value of the lay length in the wire rope strand is compared with the lay length measured by the new wire rope to determine the degree of loose twist.
2. Safety inspection parts
In general part inspection, attention should be paid to check the movement and fixed start and end of the wire rope; attention should be paid to check the rope section passing through the pulley block or bypassing the pulley block, especially any part of the wire rope bypassing the pulley under load; attention should be paid to check the rope section of the balance pulley; attention should be paid to check the rope section with corrosion, corrosion and fatigue parts.
The safety and reliability of the fixed connection part of the rope end is very important to the safety of hoisting machinery. The following safety inspection should be done for the rope end part: the wire rope led from the fixed connection end should be inspected, because fatigue broken wire or corrosion in this part is extremely dangerous; The deformation or wear of the fixing device itself should also be tested for wire rope; for the rope end fixing device with pressed or forged rope hoop, check whether there is crack and whether there is possibility of sliding between the rope hoop and the wire rope; check the broken wires and corrosion in the detachable wedge joint, rope clamp, pressure plate and other devices at the rope end and in the rope end to ensure that the rope end is the same curtain.
3. Safety inspection cycle
daily observation. The crane operator has the responsibility to observe any visible part of the wire rope as much as possible in each working day, so as to find the damage and deformation of the wire rope in time. If there is any abnormality, it should be reported to the competent department for processing.
Regular safety inspection by the competent personnel: conduct safety inspection at least once a month for general hoisting machinery and wire ropes used for hoisting and binding operations.
The competent personnel shall conduct safety inspection at least once a week on the steel wire ropes used for hoisting appliances at the construction site.
The person in charge shall conduct safety inspection on the steel wire rope used for hoisting machinery for lifting molten or hot metal, acid solution, explosives, inflammables and toxic substances at least twice a week.
To be able to do the above wire rope detection content, not only can extend the service life of the wire rope, but also can eliminate the safety hazards caused by the wire rope, safe work, small things.
