Description
ULTRA-DEEP UNDERGROUND TRACTION SYSTEM ARRANGED
IN HORIZONTAL DRIVE MODE AND METHOD OF USING SAME
BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to an ultra-deep underground traction system arranged in horizontal drive mode and a method of using same, applicable to a multi-rope traction system for an ultra-deep vertical well and particularly applicable to a large-load hoisting system.
Description of Related Art For modem industry, exploitation and utilization of mineral resources are extremely important from the perspectives of both energy and production. From the beginning of the industrial revolution to the present day, long-term mining has made it difficult to maintain efficient industrial development from mineral resources near the surface. Exploiting resources deep in the earth is an issue that many countries must consider today, and therefore, it is crucial to develop ultra-deep well mining technology.
A mine hoisting system features prominently in ultra-deep well mining engineering, and the quality of a traction system directly determines the mining efficiency. Because common hoisting systems generally use a head sheave as a drive device, the drive device not only is subjected to natural abrasion but also needs to bear a heavy load from hoisted minerals, which undoubtedly reduces the service life of the system and may further cause an accident. Therefore, it is of great significance to improve a structural arrangement of the traction system by specific means.

To make the objective, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Apparently, the described embodiments are some rather than all of the embodiments of the present invention. Based on the described embodiments of the present invention, other embodiments acquired by those of ordinary skill in the art without creative effort all belong to the scope of protection of the present invention.
FIG. 1 shows an overall layout of an ultra-deep underground traction system arranged in horizontal drive mode in a preferred embodiment of the present invention.
The system includes two head sheaves, two horizontally symmetrically arranged multi-rope guide pulleys, four drive drums, four double winding drums that are attached to the drive drums respectively, two containers, two reels, eight horizontally symmetrically arranged single-rope guide pulleys, four driving steel wire ropes, and one driven steel wire rope. The two containers are a left container 3-1 and a right container 3-2. The two head sheaves are a main head sheave 1-1 and an auxiliary head sheave 1-2. A multi-rope guide pulley set is formed by a left multi-rope guide pulley 5-1 and a right multi-rope guide pulley 5-2. Each drive drum set is formed by one drive drum (successively from a left drive drum I 7-1-1, a left drive drum II 7-2-1, a right drive drum I 7-3-1, and a right drive drum II 7-4-1) and one double winding drum (successively from a left double winding drum I 7-1-2, a left double winding drum II
7-2-2, a right double winding drum I 7-3-2, and a right double winding drum II
7-4-2) that are corresponding to each other. Two left-side drive drum sets formed by the left drive drums and the left double winding drums are symmetrical to the two right-side drive drum sets formed by the right drive drums and the right double winding drums about a central axis of the main head sheave 1-1. Each drive drum is provided with eight rope grooves, each double winding drum is provided with four rope grooves, and each multi-rope guide pulley is provided with four rope grooves. Each single-rope guide pulley set is formed by two corresponding guide pulleys. Specifically, a left single-rope
6 Date Recue/Date Received 2020-09-01 guide pulley I 6-1 and a left single-rope guide pulley II 6-2 form a left-side single-rope guide pulley set, and a left single-rope guide pulley III 6-3 and a left single-rope guide pulley IV 6-4 form a right-side single-rope guide pulley set. The four left single-rope guide pulleys and the four right single-rope guide pulleys in all single-rope guide pulley sets are relatively staggered in an axial direction. Rope grooves in the single-rope guide pulley sets around which the four driving steel wire ropes are respectively wound are one-to-one corresponding to the four rope grooves in each of the four double winding drums. A tension balance control system is formed by a pump station 12, a left-side hydraulic cylinder set 10-1, a left-side hydraulic pipeline 10-2, a right-side hydraulic cylinder set 11-1, a right-side hydraulic pipeline 11-2, a reel 113, and a reel 11 14. The tension balance control system is used to control the left-side and right-side single-rope guide pulley sets independently. That is, the hydraulic pipeline 10-1 is not communicated with the right-side hydraulic cylinder set 11-1. In the tension balance control system, each single-rope guide pulley in the left-side and right-side single-rope guide pulley sets is fitted with a hydraulic cylinder, and has a degree of freedom to move left or right in a horizontal direction.
Referring to FIG. 1 continuously, the main head sheave 1-1 is disposed above the ground, and the auxiliary head sheave 1-2 is disposed at the right side below the main head sheave 1-1. The driven steel wire rope 2 is wound through the half circumference of an upper rim of the main head sheave 1-1 and hangs down from its two ends.

FIGs. 10-1 and 10-2 show a connection manner of steel wire ropes on the bottoms of the left container 3-1 and the right container 3-2 respectively. The reel 113 and the reel 11 14 are provided on the bottom of the left container 3-1. The first driving steel wire rope 9-1 and the second driving steel wire rope 9-2 are wound onto the reel 113, the third driving steel wire rope 9-3 and the fourth driving steel wire rope 9-4 are wound Date Recue/Date Received 2020-09-01 onto the reel 11 14, and the four driving steel wire ropes extend out from the two sides of their corresponding reel 113 or reel 11 14. A specific arrangement is described with reference to FIG. 10-1. The reel 113 and the reel 11 14 are fixedly arranged on the bottom of the left container 3-1 via a bearing support. For the two driving steel wire ropes wound onto each reel 113, one end of each driving steel wire rope is connected to the reel 113 via a rope fastener on the outer cylinder of the reel 113 that is close to its end face. The two hoisting steel wire ropes are spirally wound on the reel 113 in the same direction. Rope extension ends of the two driving steel wire ropes are located on the middle part of a reel shaft, and the ropes both extend out from the lower side of the reel 113.
When the left container 3-1 is hoisted, the main head sheave 1-1, the drive drum sets (including the left-side drive drum sets and the right-side drive drum sets), and the single-rope guide pulley sets rotate clockwise, while the auxiliary head sheave 1-2 and the multi-rope guide pulley set rotate counterclockwise. A closed system formed by the driving steel wire rope set and the driven steel wire rope 2 move clockwise along corresponding winding paths. When the right container 3-2 is hoisted, rotation directions of the wheels and a motion status of the steel wire ropes are contrary to those in the case where the left container 3-1 is hoisted.
When the left side and the right side of the driving steel wire rope set are subjected to unequal tension forces, tension forces on the four driving steel wire ropes are transmitted to their respective corresponding hydraulic cylinders in the left-side hydraulic cylinder set 10-1 via the four left single-rope guide pulleys. The left-side hydraulic cylinder set 10-1 performs operations by control through the left-side hydraulic pipeline 10-2, to readjust the positions of the four left single-rope guide pulleys so that the steel wire ropes at the left side of the driving steel wire rope set are subjected to an equal tension force, and then the hydraulic cylinders in the left-side hydraulic cylinder set 10-1 stop operations and the four left single-rope guide pulleys stop movement. Tension forces on the steel wire ropes at the right side of the driving steel wire rope set are transmitted to their respective corresponding hydraulic cylinders in the right-side hydraulic cylinder set 11-1 via the four right single-rope guide pulleys.
The hydraulic cylinders in the right-side hydraulic cylinder set 11-1 perform operations by control through the right-side hydraulic pipeline 11-2, to readjust the positions of the four right single-rope guide pulleys so that the steel wire ropes at the right side of Date Recue/Date Received 2020-09-01 the driving steel wire rope set are subjected to a tension force equal to that on the driving steel wire ropes at the left side, and then the hydraulic cylinders in the right-side hydraulic cylinder set 11-1 stop operations and the four right single-rope guide pulleys stop movement.
The first driving steel wire rope 9-1 and the second driving steel wire rope 9-wound onto the reel 113 apply torque with a rotational inclination on the reel 113 in opposite directions. The reel 113 rotates from a side at which the tension force is smaller between the first driving steel wire rope 9-1 and the second driving steel wire rope 9-2.
The steel wire rope subjected to a large tension force turns slack on the reel, while the one subjected to a small tension force tightens around the reel. After the tension forces on the two steel wire ropes become equal, the reel stops rotation. A tension adjustment manner for the third driving steel wire rope 9-3 and the fourth driving steel wire rope 9-4 wound onto the reel 11 14 is identical with that for the reel 113.
The above merely describes preferred embodiments of the present invention, and is not intended to limit the present invention in any form. Any simple modifications and equivalent changes made to the foregoing embodiments according to the technical essence of the present invention all fall within the scope of protection of the present invention.

For the two driving steel wire ropes wound onto each reel 113, one end of each driving steel wire rope is connected to the reel 113 via a rope fastener on the outer cylinder of the reel 113 that is close to its end face. The two hoisting steel wire ropes are spirally wound on the reel 113 in the same direction. Rope extension ends of the two driving steel wire ropes are located on the middle part of a reel shaft, and the ropes both extend out from the lower side of the reel 113.
When the left container 3-1 is hoisted, the main head sheave 1-1, the drive drum sets (including the left-side drive drum sets and the right-side drive drum sets), and the single-rope guide pulley sets rotate clockwise, while the auxiliary head sheave 1-2 and the multi-rope guide pulley set rotate counterclockwise. A closed system formed by the driving steel wire rope set and the driven steel wire rope 2 move clockwise along corresponding winding paths. When the right container 3-2 is hoisted, rotation directions of the wheels and a motion status of the steel wire ropes are contrary to those in the case where the left container 3-1 is hoisted.
When the left side and the right side of the driving steel wire rope set are subjected to unequal tension forces, tension forces on the four driving steel wire ropes are transmitted to their respective corresponding hydraulic cylinders in the left-side hydraulic cylinder set 10-1 via the four left single-rope guide pulleys. The left-side hydraulic cylinder set 10-1 performs operations by control through the left-side hydraulic pipeline 10-2, to readjust the positions of the four left single-rope guide pulleys so that the steel wire ropes at the left side of the driving steel wire rope set are subjected to an equal tension force, and then the hydraulic cylinders in the left-side hydraulic cylinder set 10-1 stop operations and the four left single-rope guide pulleys stop movement. Tension forces on the steel wire ropes at the right side of the driving steel wire rope set are transmitted to their respective corresponding hydraulic cylinders in the right-side hydraulic cylinder set 11-1 via the four right single-rope guide pulleys.
The hydraulic cylinders in the right-side hydraulic cylinder set 11-1 perform operations by control through the right-side hydraulic pipeline 11-2, to readjust the positions of the four right single-rope guide pulleys so that the steel wire ropes at the right side of Date Recue/Date Received 2020-09-01 the driving steel wire rope set are subjected to a tension force equal to that on the driving steel wire ropes at the left side, and then the hydraulic cylinders in the right-side hydraulic cylinder set 11-1 stop operations and the four right single-rope guide pulleys stop movement.
The first driving steel wire rope 9-1 and the second driving steel wire rope 9-wound onto the reel 113 apply torque with a rotational inclination on the reel 113 in opposite directions. The reel 113 rotates from a side at which the tension force is smaller between the first driving steel wire rope 9-1 and the second driving steel wire rope 9-2.
The steel wire rope subjected to a large tension force turns slack on the reel, while the one subjected to a small tension force tightens around the reel. After the tension forces on the two steel wire ropes become equal, the reel stops rotation. A tension adjustment manner for the third driving steel wire rope 9-3 and the fourth driving steel wire rope 9-4 wound onto the reel 11 14 is identical with that for the reel 113.
The above merely describes preferred embodiments of the present invention, and is not intended to limit the present invention in any form. Any simple modifications and equivalent changes made to the foregoing embodiments according to the technical essence of the present invention all fall within the scope of protection of the present invention.
