1. Reasonable choice of wire rope

Different functions have different requirements for wire rope, and the rotation of wire rope is an important reference index. The wrong choice will bring great harm to the service life of the pulley. For a single group of pulleys, the steel wire rope should be selected to prevent rotation. For the guided load, the steel wire rope that can rotate should be selected. For the steel wire rope used on the drum, as it often bends during use, the torsion amount of the rope begins to accumulate gradually. In order to prevent the impact on the strength of the steel wire rope, should choose the core and the outer strand of the opposite rotation direction of the model, this model in use because of the inner and outer two layers of rope between the winding direction is opposite, the rotation torque will cancel each other, the free end is not easy to produce rotation, while the increase of the support point also makes its strength is greater, to the safe use of wire rope has brought greater protection. The reasonable choice of wire rope will have a direct impact on its service life, and it should be flexibly selected according to the functional requirements in the actual use process.

2. Scientific wire rope detection means

At present, the diagnosis of steel wire rope mostly stays in the manual detection stage. This diagnosis method can only detect some damage problems of steel wire rope from the appearance, and cannot detect the potential safety hazards inside. For example, even if the appearance of steel wire rope used for a long time does not see serious damage, a large number of steel wire fractures have occurred inside, and there are great potential safety hazards in continued use. The use of weak magnetic detection technology can quickly and accurately detect the internal problems of the wire rope without changing the function of the wire rope. Through regular diagnosis of the wire rope, it can ensure that the damaged wire rope is found in time, and it can save the replacement cost of the wire rope. Great help.

3. Ensure adequate lubrication

The wire rope used on the winch is a safety part. The wire rope is generally lubricated and rust-proof before leaving the factory, but it can only play a role in storage, transportation and the initial stage of use. During long-term use, the original lubricating oil will slowly be lost and distributed. Therefore, it is necessary to strengthen lubrication and maintenance and regularly apply lubricating oil to the wire rope to ensure that the oil film is attached to the inner and outer surfaces of the wire rope, thus ensuring the traction and prolonging, to reduce the occurrence of accidents, wire rope lubricants have four main functions:

1) Reduce the friction and wear caused by the movement of the wire rope between the wires, between the strands and the wire rope and the pulley, and reduce the possibility of fracture;

2) Provide internal and external anti-corrosion protection for the core, steel wire and each strand of the wire rope, reduce corrosion and extend the life of the wire rope;

3) Increase the flexibility of the wire rope, so that the load is evenly distributed on the strands, and reduce bending fatigue;

4) The lubricant applied on the wire rope can be used as a buffer between the wire rope and the pulley block and the roller. Lubricant is an important component of wire rope, which is often underestimated. If the wire rope does not have enough lubricating oil, or if the wrong lubricating oil is used, it will inevitably lead to premature fatigue damage or internal corrosion of the wire rope. For the selection of lubricating oil for steel wire rope, the following principles must be followed: 1) good adhesion; 2) good permeability; 3) low volatility; 4) high extreme pressure and wear resistance;

5) Strong corrosion resistance;

6) the role of anti-external interference to be strong.

The safety and economic analysis of the wire rope used by the ship unloader is important for improving.wire ropeutilization efficiency, prolong the service life of wire rope has a positive significance. Due to the special use environment of the wire rope, it is easy to be damaged under repeated loads. Once the wire rope breaks, it will cause serious safety accidents. Therefore, it is necessary to regularly detect and analyze the service life of the wire rope. Combined with the functional requirements of the wire rope, the safety and economy of the wire rope can be effectively improved by selecting a reasonable wire rope model, regularly carrying out non-destructive testing of the wire rope, and strengthening the lubrication of the wire rope.
