Maintain and maintain hoist ropes. According to relevant data, it is known from the above analysis that the lubrication of the steel wire rope has a great influence on the service life of the steel wire rope. Systematic lubrication of the steel wire rope can prolong the life of the steel wire rope by 23 times. Therefore, the wire rope should be lubricated on schedule, especially the steel wire rope of the elevator. Maintenance work is more important, and it is often in a good lubrication state. Being in a good lubrication condition is often in a good lubrication condition and is often in a good lubrication condition. The wire rope is constantly passing through the pulley groove and reel, and the wire rope should be checked regularly. When the lifting agency is working. To be subjected to pulling, squeezing, friction, torsion and other loads, at the same time, as the wire rope passes through a series of pulleys, it is repeatedly subjected to the repeated effects of bending and squeezing. This can cause fatigue and broken filaments, as well as other factors such as wear and corrosion. ,Increasing the development of broken wire rope, therefore, the wire rope should be subjected to a visual inspection once a week, a thorough and thorough detailed inspection should be carried out every month, and a small number of broken wires should be properly disposed to prevent broken wires from breaking other wires; Individual sections of steel wire rope should be cut off in time. For example, if the wire rope is not properly fixed and the torque is out of balance, bird cage phenomenon will occur near the anchorage end. If it is not cut off in time, it will affect the life of the entire wire rope. For the non-reversing wire rope, because of its special structure, it must not damage or interfere with the fixed pitch between the original strands when entangled around, so as to prevent the rope core from sliding or the outer layer strands from loosening to form the birdcage shape. The wire rope is an important part in the hoisting mechanism. Under the condition of ensuring the manufacturing quality, the use factor has a great influence on the service life of the wire rope. Otherwise, the wire rope will diverge during winding on the reel, which will reduce the service life of the wire rope. In the pulley group shown in Fig. 1 , when the steel wire rope bypasses the pulley block, the wire rope is subjected to many reverse bendings, and the direction of its bending stress also changes. Under the action of this alternating stress, the life of the wire rope must be reduced. Therefore, the pulley block In use, it is preferable to use the wire rope shown in Fig. 3 as a pulley block that is bent in the same direction. The entanglement of the steel wire rope directly affects the service life of the wire rope or does not exceed 2 °, and the use and maintenance have a great influence on the service life of the steel wire rope. Select the type of wire rope and pulley material, inspection, maintenance and use by the professional staff on schedule, and ensure that the declination angle α ≤ 1 ° 30 ′ produced by the line connecting the center line of the wire rope with the reel and pulley axis . Will extend the life of the rope and reduce it Construction interest, ensure the construction period, and improve economic efficiency. Before the wire rope is lubricated, the dirt and rust on the outside of the wire rope should be removed and the grease should be heated to about 60 ° C so that the grease can fully penetrate into the wire rope. Preventing the wire rope from bending several times in the opposite direction prevents the wire rope from bending backwards several times and prevents the wire rope from bending backwards several times to prevent the wire rope from bending backwards many times. The wire ropes constantly pass through the pulley grooves and reels, and talk about the impact of the maintenance of the lifting crane wire rope on its life: when the lifting mechanism is working. To be subjected to pulling, squeezing, friction, torsion and other loads, at the same time, as the wire rope passes through a series of pulleys, it is repeatedly subjected to the repeated effects of bending and squeezing. This can cause fatigue and broken filaments, as well as other factors such as wear and corrosion. ,Increasing the development of broken wire rope, therefore, the wire rope should be subjected to a visual inspection once a week, a thorough and thorough detailed inspection should be carried out every month, and a small number of broken wires should be properly disposed to prevent broken wires from breaking other wires; Individual sections of steel wire rope should be cut off in time. For example, if the wire rope is not properly fixed and the torque is out of balance, bird cage phenomenon will occur near the anchorage end. If it is not cut off in time, it will affect the life of the entire wire rope. If the hoisting mechanism uses a right-handed wire rope, the rope must be wound from above the drum when the rope drum groove runs from left to right . As shown in Fig. 2a, when the drum rope groove runs from right to left, the rope must be Below the drum, as shown in Fig. 2b, if the hoisting mechanism uses a left-handed wire rope, the rope must be taken out from under the drum when the rope drum groove runs from left to right, as shown in Fig. 2c. Right to left, the rope must be wound out from above the drum, as shown in Figure 2d. Therefore, the winding of the wire rope must be performed by professional staff to ensure that the entanglement is accurate and the service life of the rope is guaranteed.
