Problems solved by technology

In this application, the wire rope group of each main shaft device pulls the same lifting container, which causes a large torque difference between the main shaft device pulling the empty container and the heavy-duty container, and the gear transmission system between the two main shaft devices needs to bear Larger loads, and the required gear size is larger, resulting in a larger moment of inertia

Abstract

The invention discloses a multi-rope lifting system for an ultra-deep vertical shaft and a guiding method of the multi-rope lifting system, and belongs to the technical field of mine lifting. The multi-rope lifting system comprises an upper guiding wheel system, a lower guiding wheel system, a front lifting container, a rear lifting container, a driving unit, a front lifting rope, a rear lifting rope, a tail rope and a plurality of balance head ropes, wherein the front lifting rope is lapped on the upper guiding wheel system, one end of the front lifting rope is connected with the top of the front lifting container, and the other end of the front lifting rope is connected with the driving unit; the rear lifting rope is lapped on the lower guiding wheel system, one end of the rear lifting rope is connected with the top of the rear lifting container, and the other end of the rear lifting rope is connected with the driving unit; one end of the tail rope is connected with the bottom of thefront lifting container, and the other end of the tail rope is connected with the bottom of the rear lifting container; and the balance head ropes are lapped on the upper guiding wheel system, one end of each balance head rope is connected with the top of the front lifting container, and the other end of each balance head rope is connected with the top of the rear lifting container. According tothe multi-rope lifting system, the balance head ropes are arranged, so that the traction load borne by the driving unit is greatly reduced, the effective service life of the driving unit is greatly prolonged, and the multi-rope lifting system for the ultra-deep vertical shaft can carry out lifting operation with larger load.

Description

technical field [0001] The invention belongs to the technical field of mine hoisting, and more specifically relates to an ultra-deep shaft multi-rope hoisting system and a guiding method thereof. Background technique [0002] At present, for the hoisting of deep wells exceeding 1800m, the single-rope winding hoisting system is used to be affected by the weight of the wire rope and the size of the hoisting drum, and the payload is small, while the double-rope Blair type hoist overcomes the small payload of the single-rope winding hoist. Disadvantages, but compared to the large load lifting capacity that can be achieved by 4 or 6 steel wire ropes through multi-rope friction, it is particularly insufficient, and the arrangement of the drum will be difficult due to the increase in the number of winding steel wire ropes. [0003] The existing multi-rope friction hoist has a large fluctuating stress on the wire rope due to the self-weight of the wire rope and the load of the conta...
