Embodiment 1

[0094] The tension self-balancing multi-rope winding lifting system of this embodiment includes,

[0095] guide wheel train 1;

[0096] Lifting container one 2 and lifting container two 3 arranged below the guide wheel train 1;

[0097] Drive unit 5, it is made up of drive unit one 50, drive unit two 51, drive unit three 52 and drive unit four 53 arranged in sequence, each drive unit structure is all the same, and mutually parallel arrangement; Each drive unit comprises drive motor 500, the main shaft 501 and the roller 502, the driving motor 500 provides the driving force for the rotation of the main shaft 501, and each main shaft 501 is socketed with two rollers 502;

[0098] Lifting rope group 6, one end of which is connected to the drum 502 in transmission, and the other end is connected to the top of lifting container 1 2 and lifting container 2 3 after bypassing the top of guide wheel system 1;

[0099] A transmission bevel gear 503 is sleeved on the main shaft 501 of ...

Embodiment 2

[0113] The tension self-balancing multi-rope winding lifting system of this embodiment is further improved on the basis of Embodiment 1. A primary tension equalization unit 70 is arranged between the drive unit one 50 and the drive unit two 51, and the drive unit three 52 and the drive unit A first-level tension equalization unit 70 is also arranged between unit four 53, and two first-level tension equalization units 70 are symmetrically arranged;

[0114] The primary tension equalization unit 70 also includes a large gear 709, which is rotatably sleeved on the second half shaft 704;

[0115] The tension equalization part 7 also includes a secondary tension equalization unit 71, which includes:

[0116] Shell two 710, which is a hollow structure, placed between the drive unit two 51 and the drive unit three 52;

[0117] There are two transmission mechanisms, symmetrically arranged on both sides of the housing two 710, each transmission mechanism includes a major shaft 711, a ...

Embodiment 3

[0125] The tension self-balancing multi-rope winding hoisting system of this embodiment is further improved on the basis of Embodiment 2. Drive unit 1 50, drive unit 2 51, drive unit 3 52 and drive unit 4 53 have their respective main shafts 501 from front to back The height position of each drive unit increases successively, and the main shafts 501 of each drive unit are all in the same plane.

[0126] Such as Figure 5 As shown, the main shafts 501 of the four driving units are in the same plane, and this plane forms an angle θ with the horizontal plane. Through the setting of this embodiment, on the one hand, it can effectively prevent the contact interference between the lifting ropes. On the other hand, this Compared with directly arranging the main shafts 501 on the horizontal plane, the arrangement can make the hoisting ropes on the rear row of drums 502 obtain a smaller chord length and reduce the amplitude of the hoisting ropes, thereby preventing the hoisting ropes f...

Abstract

The invention discloses a tension self-balancing multi-rope winding hoisting system and method, belonging to the field of mine hoisting. The lifting system includes a guide wheel train; a lifting container 1 and a lifting container 2 arranged under the guide wheel train; a driving part, which is composed of four driving units arranged in sequence; and a lifting rope group; and a tension equalization part, which includes A primary tension equalization unit placed between adjacent drive units, the primary tension equalization unit is connected to the main shafts of the drive units on both sides of the primary tension equalization unit respectively. The invention balances the tension through the first-level tension equalization unit, and through the revolution and rotation of the bevel gear five, it can balance the different torques on both sides of the first-level tension equalization unit, and finally ensure that the driving force output by the drive unit is equal. The purpose of balancing the tension is achieved, the structure is simple and light, and it is suitable for the working environment of the mine without increasing the load of the system.

Description

technical field [0001] The invention belongs to mine hoisting technology, more specifically, it relates to a self-balancing multi-rope winding hoist which is applied to super-deep vertical shafts with friction wheel suspension traction and multi-rope winding mixed traction, and can also be used for multi-rope winding traction. The system and method are also applicable to special elevators with multi-rope winding, hoisting machinery and port machinery suspension hoisting machinery and the like. 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. However, compared with the large-load lifting capacity that can be achieved by multi-rope friction through 4 or 6 steel wire ropes, it is still ...
