Deviation measurement method for head rope length and rope groove diameter

Abstract

The invention relates to a deviation measurement method for a head rope length and a rope groove diameter. The deviation measurement method comprises the following steps that cages are put at a well mouth, skips are put at the bottom of a well, the cage and the skip are installed on each head rope, and a tension automatic balancing device is installed at each cage and each skip of each head rope;oil cylinder stroke data of the tension automatic balancing device at each cage are measured, and the oil cylinder stroke data are sequentially recorded according to the sequence; meanwhile, the oil cylinder stroke data of the tension automatic balancing device at each skip at the bottom of the well are measured, and are recorded in sequence according to the sequence; and after the measurement isfinished, the skips are lifted to the well mouth, the cages are arranged at the bottom of the well, and the oil cylinder stroke data of the tension automatic balancing device at the cages and the skips are recorded correspondingly and accurately through the same method. The method has the advantages that the defects of blind rope feeding and empirical rope feeding are overcome, and a traditional rope groove measuring method is replaced, so that the diameter difference measurement of a rope groove is more scientific and reasonable.

Description

technical field [0001] The invention relates to a method for measuring the deviation of the length of the first rope and the diameter of the rope groove. Background technique [0002] The force balance of the first rope and steel wire rope of multi-rope friction hoist has always been the focus and difficulty of the hoisting system management. At present, the tension automatic balance device is often used to adjust the tension between the hoisting container and the first rope, but the adjustment range of the oil cylinder of the tension balance device is limited. When it exceeds the adjustment range, it is necessary to adjust the length deviation of the first rope or turn the rope groove. Among them, the length deviation of the first rope and the diameter deviation of the rope groove play a key role in the force of the first rope steel wire rope, so how to accurately measure the length deviation of the first rope and the diameter deviation of the rope groove is particularly im...

[0002] The force balance of the first rope and steel wire rope of multi-rope friction hoist has always been the focus and difficulty of the hoisting system management. At present, the tension automatic balance device is often used to adjust the tension between the hoisting container and the first rope, but the adjustment range of the oil cylinder of the tension balance device is limited. If it exceeds the adjustment range, it is necessary to adjust the first rope length deviation or turn the rope groove

As a result, in the process of rope adjustment, we either intercepted the wire rope too long, or the intercepted wire rope did not meet the expected requirements; and because the "Safety Regulations for Metal and Nonmetal Mine" required that the diameter deviation of the rope groove should not be greater than 0.8mm, while the traditional direct measurement , diameter measurement and other methods have large errors, and it is impossible to accurately measure the deviation between the diameters of each rope groove, which will lead to inaccurate turning and low work efficiency, which prolongs the maintenance time and fails to achieve the expected effect

There is a certain blindness in the operation process, and such blindness will lead to uneven stress on the first rope, accelerate the wear of the drum friction pad, and shorten the service life of the first rope. production safety
