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 hoisting system for an ultra-deep vertical shaft and a guiding method thereof, belonging to the technical field of mine hoisting. It includes an upper guide wheel system; a lower guide wheel system; a front lifting container; a rear lifting container; a drive unit; a front lifting rope, which rides on the upper guide wheel system, and one end is connected to the top of the front lifting container, and the other end is connected to the drive unit; The rear hoisting rope is placed on the lower guide wheel train, and one end is connected to the top of the rear hoisting container, and the other end is connected to the drive unit; the tail rope is connected to the bottom of the front hoisting container at one end, and the other end is connected to the bottom of the rear hoisting container; it also includes a balance head Rope has several roots, rides on the upper guide wheel train, one end of the balance head rope is connected with the top of the front lifting container, and the other end is connected with the top of the rear lifting container. The invention is equipped with a balance head rope, which greatly reduces the traction load on the driving unit, greatly prolongs the effective service life of the driving unit, and enables the multi-rope hoisting system of the ultra-deep shaft to carry out lifting operations with greater loads.

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...
