Description
Technical Field
The invention relates to a steel wire rope reel of lifting machinery and a method for coiling a steel wire rope on the reel, in particular to a double-groove primary-secondary type steel wire rope reel and a method for coiling the steel wire rope.
Background
In various industrial and mining enterprises, ports and wharfs, the steel wire rope is an indispensable common part of large-scale hoisting machinery and is also one of three safety devices. The daily maintenance and service life of steel wire ropes in the industry are also strict technical specifications and standards: firstly, when the accumulated broken wire of the steel wire rope used on line exceeds 10 percent in any pitch, namely the broken wire number reaches 22 wires (the total number of the steel wire rope is 216 wires), replacement or maintenance is carried out according to the actual broken wire condition; secondly, the diameter abrasion of the steel wire rope exceeds 7% of the original diameter, and at the moment, the strength of the steel wire rope is greatly reduced, and the steel wire rope needs to be replaced; thirdly, using a steel wire rope with the tonnage accumulated to 250 ten thousand tons to show that the fatigue strength of the steel wire rope basically reaches the limit, and replacing the whole steel wire rope as soon as possible; the safe and stable operation of the port machine can be ensured only by implementing the replacement and repair of the steel wire rope according to the standard and the on-site use specification.
The steel wire rope used on the port hoisting mechanical equipment allows for transportation and field replacement. Referring to fig. 1, before leaving the factory, a manufacturer always takes an ordered reel of a steel cable of a desired tonnage in a drum 100 with baffles on both sides, so that a first end 101 of the steel cable 1 is pressed against the bottom of the innermost turn of the drum, while a second end 102 is exposed.
The replacement operation of the steel wire rope of the large-scale hoisting equipment comprises the steps of firstly placing an old steel wire rope on the ground, then reeling and loading a rope end 102 with exposed leading ropes and a whole new steel wire rope by using a reel of a machine room after the old steel wire rope is firmly woven by measures, and after the steel wire rope on a reel of a wharf is completely paid out, a maintainer can pour the pear-shaped rope end 101 buried at the bottommost part, the process commonly called 'steel wire rope end-making' in the industry is complex and rigorous, has high requirements and long time, particularly the cooling and solidification after the tin-based alloy is poured, is greatly influenced by the temperature of seasons and the environment, generally needs to be cooled for 2.5-3 hours in summer, and can reduce the temperature of a body of the pear-shaped end to below 50 degrees after 1.5-2 hours in winter, so that the installation of the operator is convenient. Whole large-scale hoisting machinery wire rope changes process, because the single reel coiling method that present wire rope adopted, so a fag end buries in the reel bottom all the time, only wait that whole wire rope batches the completion back, just can carry out next fag end pouring process, and the scattered strand of wire rope among this process removes oil, the first stoving of pear shape is heated and is irritated steps such as cooling after the plumbous, 50% time of whole maintenance process has been taken at least, can't accomplish synchronous and wrong peak completion between wire rope batches and the two processes of "workhead", so the maintenance process is relatively lagged behind, overhaul the operation time can't obtain effective reduction. The total time for replacing the steel wire rope of the large-scale ship unloading machine is about 8 hours, and for port and wharfs with fierce competition, the time is benefit on the premise of safety guarantee, and the production operation efficiency is often seriously influenced by the 8-hour overhaul time.
The 'rope end pouring' after the steel wire rope is replaced needs to be carried out on site, and the process is that the tin-based alloy is dissolved and poured into a treated pear-shaped rope sleeve, so that the alloy, the strand-scattered steel wire rope and the pear-shaped head are firmly bonded together. The process has strict requirements on the surrounding environment, the state and the time; the process steps can be implemented only in a production field according to the current situation, and are influenced by various factors such as mineral powder, rainwater, time, how to fix the steel wire rope and the like, so that the safety factor and the service life are reduced.
Therefore, the coiling mode of the reel steel wire rope in the prior art has a plurality of overhauling potential safety hazards and defects of long overhauling time, low working efficiency, low safety factor and the like.
