Description

Device and method for guiding round tail ropes of vertical shaft elevator in parallel rope clamping manner

Technical Field

The invention relates to the technical field of mine hoisting equipment, in particular to a round tail rope parallel rope clamping guide device and a round tail rope parallel rope clamping guide method suitable for a vertical shaft hoist.

Background

The vertical shaft hoist as mine hoisting equipment consists of motor, main shaft unit, steel cable, hoisting container, tail rope and guide track, is used in hoisting ore, lowering material, raising and lowering personnel and equipment and is the connection junction between mine shaft and ground. The tail rope is installed in two promotion container bottoms through linkage as the counter weight of vertical elevator, its both ends, plays key counter weight balanced action at the endless promotion of vertical with transfer in-process.

The tail rope is divided into a round tail rope and a flat tail rope. Compared with a round tail rope, the flat tail rope has the characteristic of absolute non-rotation, high wear resistance and small use failure. However, the flat tail rope is mainly woven by hands, the weaving quality cannot be guaranteed, the cost is high, the yield is low, and the price is high. The round tail ropes are generally two, the manufacturing technology is mature, the processing quality is reliable, the cost is low, the yield is high, the price is low, however, the round tail ropes are used as one part of the counterweight system and are easy to swing along with the container body, and the self length and weight change generate spinning, so that the two round tail ropes are easy to rub and twist in the lifting and lowering process of the container body, and the two round tail ropes are abraded, broken wires, broken strands and even pulled to be broken. In addition, as the counterweight needs, the tail rope needs to have larger mass per unit length, when two round tail ropes are adopted, a large-diameter steel wire rope needs to be adopted, and the large-diameter steel wire rope has high processing difficulty, large bending curvature radius and is easy to generate bending broken wires. In the existing research, a learner uses a plurality of thin steel wire ropes in parallel, however, on the premise that additional guiding and fixing are not added, the plurality of steel wire ropes are more prone to tangling in the process of swinging along with the container body. There are also studies to embed a plurality of parallel thin steel wire ropes in rubber to make a flat adhesive tape, however, because the tail rope needs to be circularly bent at the bottom of the shaft, the steel wire ropes are easy to separate from the rubber, and the service life is short. Therefore, it is necessary to research a parallel guide device for a plurality of round tail ropes arranged in parallel, so as to avoid the collision or kink between the plurality of round tail ropes caused by the swinging and spinning of the round tail ropes, so that the round tail rope counterweight system not only has the non-rotation characteristic of the flat tail rope and small fault probability, but also has a round tail rope parallel rope clamping guide device for a vertical shaft elevator with reliable round tail rope processing quality and high economy.
