Problems solved by technology

For 1500m and below, multi-rope friction lifting is mainly used, but for deep mines, such as greater than 1500m, or even extremely deep mines, the lifting efficiency will be reduced due to the significant increase in the weight of the lifting wire rope. Two steel wire ropes are lifted, so the diameter of the steel wire rope is too thick to meet the large-load lifting of 2000m, or even 3000m or less deep mines. In order to overcome the above-mentioned shortcomings of lifting, the present invention proposes a multi-rope winding hoist for ultra-deep mine and the winding method

Embodiment 1

[0035] Embodiment 1, as figure 1 with 2 As shown, the deep vertical shaft multi-rope winding hoist of the present invention is mainly composed of a sky wheel train and a drive system located above the wellhead, and the drive system controls the steel wire rope that bypasses the sky wheel and is connected to the lifting container. The sky wheel train includes The upper sky gear train 1 and the lower sky gear train 3; the described drive system includes: as Figure 7 Shown front drive motor group 5 and rear drive motor group 16, front axle group 7, rear axle group 11, as Figure 8 Shown front drum group 9 and rear drum group 10, front and rear drum group 9,10 are respectively installed on the front and rear axle group 7,11, and the left and right ends of front and rear axle group 7,11 are provided with successively respectively Brake disc 12 and driving motor; the two ends of the front shaft 7 of the front drum group 9 are respectively connected to the output shafts of the fro...

Embodiment 2

[0045] Embodiment 2, as image 3 , 4 As shown, it is basically the same as Example 1, and the same part is omitted. The difference is that the number of rollers in the front and rear roller groups is 1, specifically:

[0046] Engage between the front gear one 8-1 and the rear gear one 17-1 on the left and right sides of the hoist. When the front lifting wire rope 2 was promoted, the driving motor 15 on the rear side rotated clockwise; the driving motor 5 rotating direction on the front side was opposite to the rear side motor 14 rotating direction, which was counterclockwise. When the rear hoisting wire rope 4 was promoted, the front drive motor unit 5 rotated clockwise; the rear side motor 14 rotation direction was opposite to the front drive motor unit 5 rotation direction, which was counterclockwise.

Embodiment 3

[0047] Embodiment 3, as Figure 5 , 6 As shown, it is basically the same as Example 1, and the same part is omitted. The difference is that the number of rollers in the front and rear roller groups is 3, specifically:

[0048] The front gear 1 8-1 on the front side of the drum in the front drum group 9 meshes with the front gear 2 8-2 through a front auxiliary wheel 15-1, and the front gear 2 8-2 and the front gear 3 8-3 Engage with 1 auxiliary wheel 15-2, the rear gear one 17-1 and the rear gear two 17-2 on the left and right sides of the drum in the rear drum group 10 are engaged by the rear auxiliary wheel 14-1, and the rear gear two 17-2 2 meshes with the gear 17-3 through an auxiliary wheel 14-2. The rotation directions of the front and rear drive motor groups 5 and 16 are opposite, that is, when the front hoisting wire rope 2 is lifted, the rear drive motor group 16 rotates clockwise; on the contrary. When the rear wire rope 4 was promoted, the drive motor 5 on the ...

Abstract

The invention discloses a multi-rope winding elevator for a deep vertical shaft and a winding method. The multi-rope winding elevator comprises an upper hoisting sheave system, a lower hoisting sheave system as well as a drive system which consists of a drive motor, front rollers and rear rollers, wherein rollers on front and rear roller groups are connected with upper and lower hoisting sheave groups of upper and lower sheave systems through steel wire ropes in a winding mode; a gear and a motor are arranged at the two sides of each roller of the rear roller group; rollers on the front and rear roller groups are engaged with each other through respective gears and an auxiliary gear between every two rollers; and the front and rear roller groups are engaged together through gears of every two adjacent two rollers. During winding, motors on the rollers of the front and rear roller groups drive the rollers to rotate in reverse directions, and two lifting containers are lifted in a mode that steel wire ropes wound on the front and rear rollers get across the upper and lower hoisting wave systems. The multi-rope winding elevator is simple in structure, is convenient to operate, reduces diameters of the hoisting steel wire ropes and the rollers, reduces an outlet rope deflection angle, increases an extra-deep distance and improves efficiency.

Description

technical field [0001] The invention relates to a winding hoist and a winding method, which are especially suitable for winding and lifting personnel and materials in extremely deep shafts of mines. Background technique [0002] With the increasing shortage of global resources and energy, many countries in the world are developing and utilizing mineral resources deeper in the earth. For example, Australia first proposed the "Glass Earth" plan at the beginning of this century to make the 1000m underground "transparent"; Canada recently proposed a plan to develop 3000m underground resources; South Africa's ultra-deep gold mines have reached a depth of more than 4800m below the surface. The "National "Twelfth Five-Year" Science and Technology Development Plan" also proposes to strengthen research on the three deeps (deep sea, deep ground, and deep space). There are two types of shaft hoists: winding hoist and friction hoist. For 1500m and below, multi-rope friction lifting is...
