Description
Technical Field
The invention relates to a monitoring device and a control method, in particular to a device for monitoring rotation of a round tail rope of a friction type mine hoist and a control method, and belongs to the technical field of mine hoisting.
Background
The mine hoist is a main transportation device which is connected with the underground and the ground in mining engineering, is arranged on the ground, drives a hoisting container to run along a shaft or a slope by means of a steel wire rope, and is widely applied to lifting coal, ores and gangue, lifting personnel, lowering materials, tools, equipment and the like in shafts and inclined shafts. The common mine hoist forms in China are mainly a single-rope winding type and a multi-rope friction type.
In a multi-rope friction type mine hoist system, it is necessary to adopt a balance tail rope in order to reduce the tension difference between the steel wire ropes on the hoisting side and the lowering side. The balance tail rope suspension device is divided into a flat tail rope suspension device and a round tail rope suspension device, the two devices have the same effect, and the tension difference between the steel wire ropes on the lifting side and the lowering side is reduced through the weight change of the tail rope, so that the overall balance of the elevator system is achieved. Most of the current friction type hoisting machines use a round tail rope suspension device.
Because the round tail rope is also a steel wire rope and also has a steel wire twisting direction, in the lifting operation process of the round tail rope following the lifting machine system, the round tail rope can rotate around the central axis thereof due to the twisting direction of the round tail rope and the toughness action of the steel wire, so that two ends of the round tail rope are required to be connected with a round tail rope suspension device arranged at the bottom of the lifting container through a plane bearing, and just because the round tail rope rotates in the lifting operation process of the lifting machine system, if the round tail rope breaks down, the adjacent round tail ropes are easily twisted.
Because the round tail rope suspension device is arranged at the bottom of the lifting container or the balance weight, daily point inspection and oiling are difficult, and the probability of the round tail rope failure is increased. The round tail rope fault has the following characteristics: 1. broken filaments of the round tail rope are not easy to spot-detect, and generally found after strand breakage occurs and scattered strands are wound on other round tail ropes to break down; 2. when the round tail rope runs, natural swinging can occur due to the self stress action, and rope twisting faults can occur due to the fact that the round tail rope swings or is wound together with other facilities in a well; 3. after a plane bearing of the round tail rope suspension device is abraded, twisting rotating force of the round tail rope cannot be timely released, and the round tail rope is broken and twisted or damaged. The existing round tail rope monitoring device is mostly arranged for preventing kinking between round tail ropes, a partition plate and a kinking alarm mechanism are usually arranged between the round tail ropes, namely, the alarm is carried out after the rope twisting fault occurs, however, the traditional monitoring mode cannot fundamentally solve the problem of the round tail rope fault, and the alarm is carried out after the rope twisting fault occurs, so that the equipment maintenance cost is usually high.
