Description

Technical Field

[0001] The invention relates to the technical field of lifting systems, and in particular to an ultra-deep well winding and friction composite depth adaptive lifting system and method. Background Art

[0002] The hoisting system is responsible for the lifting of coal, personnel and materials. As the mining depth of mines continues to increase, the winding hoisting system is more suitable for deep mining in mines than the friction hoisting system. However, the multi-layer winding method of the winding hoisting system will cause the wire rope to be squeezed due to the weight of the material and the weight of the wire rope, which will significantly reduce the service life of the wire rope. In addition, the probability of wire rope winding errors is greatly increased under high-tension multi-layer winding conditions, which seriously affects the working safety of the hoisting system, requires frequent replacement of wire ropes, and affects the working efficiency and economic benefits of the mine.

[0003] The Chinese patent application with publication number CN220702963U, a single-rope winding mine hoist, uses a tensioning mechanism for preventing rope overlap and an anti-overlapping rope limiter to work together, so that when rope overlap occurs in the single-rope winding type, an alarm is triggered and the hoist stops running. However, the device only prevents and alarms rope overlap, and is not safe and reliable enough.

[0004] The Chinese patent application with publication number CN217708476U is an interlayer transition device for the drum of an ultra-deep mine hoisting system. The interlayer transition device provided allows the steel wire rope near the rope retaining plate to smoothly change direction and climb to the next layer, but it cannot improve the situation where the high-tension interlayer steel wire ropes squeeze each other.

[0051] like Figure 7 As shown, the steel wire rope 5 is wound from the lifting container to the active friction drum 16, and comes out from the active friction drum 16 after being wound multiple times between the active friction drum 16 and the passive friction drum 21. The specific winding direction is: A→B→C→D→E→F→G→H.

[0053] like Fig.12 As shown, the height of the guide wheel 31 can be adjusted by adjusting the extension and retraction of the hydraulic cylinder 35, thereby changing the envelope angle of the wire rope, so that the tension difference at both ends of the active friction drum can be adjusted to adjust the tension of the wire rope drawn out of the winding rope storage device.

[0054] like Figure 8-11 As shown, the active drive device also includes: a reversing gear set 18 and a brake 17; the reversing gear set 18 is arranged between the two active friction reels 16 and the two winding reels 45. Taking the active friction reel 16 as an example, the active friction reel 16 close to the motor 11 is the active side; the other active friction reel 16 is the driven side, the motor drives the active friction reel on the active side to rotate, and the active friction reel on the active side drives the active friction reel on the driven side to rotate in the opposite direction through the reversing gear set, and the reversing gear set 18 changes the movement direction of the wire rope 5 to realize two-way transportation of the cage bucket and the like; the reversing gear set 18 includes an active bevel gear 181, a steering bevel gear 182 and a driven bevel gear 183. For active friction reels 16 with different steering directions, the reversing gear set 18 is as follows Fig.10 The parallel connection shown and Fig.11 There are two series connection modes shown. In the parallel connection mode, the axes of the two active friction drums 16 are parallel, the two input shafts are coaxially connected to the active bevel gear 181 and the passive bevel gear 183 respectively, and both ends of the steering bevel gear 182 are helical teeth, which are respectively meshed with the active bevel gear 181 and the passive bevel gear 183; in the series connection mode, the axes of the two active friction drums 16 are coaxial, the two input shafts are coaxially connected to the active bevel gear 181 and the passive bevel gear 183 respectively, there are two steering bevel gears 182, the two steering bevel gears 182 are arranged opposite to each other, and the steering bevel gears 182 are respectively meshed with the active bevel gear 181 and the passive bevel gear 183.

[0055] The brake 17 is arranged on the active friction reel 16 on the driven side to brake the active friction reel 16 on the driven side, and the start and stop states of the active friction reel on the driven side are controlled by the brake to adjust the relative positions of the lifting containers on both sides.

The brake 17 in the winding rope storage device and the brake 17 in the active drive device act synchronously, and the relative positions of the lifting containers on both sides are adjusted by the brake.

[0058] like Figure 8 As shown, in Fig. 9 Based on the winding rope storage device shown, the motor 41, the reducer 42 and the coupling 43 can be omitted; since the movement directions of the two lifting containers are opposite, the traction force of the wire rope can be provided by the gravity assistance of the downwardly moving lifting container, and the motor can be omitted to reduce costs and power consumption.
