Technical Field

The invention relates to a mining ultra-deep well double-steel-wire-rope lifting system, in particular to a tension balancing device for balancing the tension difference of two lifting ropes and releasing the torque of the lifting ropes, which is used for the mining ultra-deep well lifting system.

Background

The ultra-deep well of the coal mine ultra-deep well hoisting system refers to that a deep well with a mine well exceeding kilometers is an ultra-deep well, the traditional single-rope winding type hoisting system is generally suitable for a mine well with a depth of more than 300m, the multi-rope friction hoisting system is generally used for a mine well with a depth of 300 plus 1400m, when the depth is increased, the effective hoisting load, the service life of a rope and the like of the multi-rope friction hoisting system are rapidly reduced, and the system is not suitable for hoisting the deep well.

In order to solve the lifting problem of the ultra-deep well, the double-rope winding type parallel lifting system becomes an effective lifting type for deep resource development, however, due to the interference of external factors such as driving difference, the lengths of two ropes cannot be completely guaranteed to be the same, the lifting container can be inclined, and due to the spiral twisting structure of the lifting rope, the torque can be generated when the lifting rope bears longitudinal load, and the service life of the lifting rope can be seriously influenced by the alternating torque.

The rope adjusting distance of a first rope suspension device of an existing multi-rope friction hoisting system is about 1m, and the application of the first rope suspension device in an ultra-deep well is limited, for example, the first rope suspension device is named as a compensation method of a multi-rope winding type hoisting machine steel wire rope synchronous compensation wheel with the publication number of CN105173974A, the rope adjusting method provided by the document is simple, convenient and effective, the rope adjusting distance is large, but the hoisting rope is influenced by bending stress for a long time, the torque of the hoisting rope cannot be released, fatigue damage is easily caused, and therefore the hoisting rope needs to be frequently replaced.

Disclosure of Invention

The invention aims to provide a tension balancing device which is simple in structure and is used for an ultra-deep well double-rope parallel winding type lifting system.

The above object is achieved by the following technical solution.

A tension balancing device for a double-rope parallel winding type lifting system of an ultra-deep well comprises a lifting rope, a wedge-shaped rope ring, a untwisted rope clamp, a balancing rope, a balancer and a lifting container; the method is characterized in that:

the tension balancing system of the U-shaped double-rope parallel winding type lifting system is characterized in that a lifting container is connected to the lower portion of the balancer, the upper portion of the balancer penetrates through two rollers in the balancer through the balancing rope and extends upwards from the left side and the right side of the top end of the balancer to be connected with a first wedge-shaped rope ring, and the second wedge-shaped rope ring and the lifting rope are connected through the untwisting rope in a clamping mode.

In the above technical solution, the method is further characterized in that: the balancer is composed of a shell and two balancing rollers symmetrically arranged on the middle shaft of the shell; the balance roller is fixedly connected to the shell through a bearing; the balance rope penetrates through the balancer and bypasses the two balance rollers to realize tension balance.

The technical scheme is realized, compared with the prior art, the double-rope parallel winding type lifting system has the advantages and positive effects that in the double-rope parallel winding type lifting system, due to the characteristics difference of the steel wire ropes, external excitation and other factors, the difference of the rope lengths inevitably occurs in the lifting process, so that the lifting container is enabled to deflect and transversely swing due to uneven stress, in addition, due to the spiral twisting structure of the steel wire ropes, the steel wire rope parallel winding type lifting system can generate axial torque when bearing longitudinal tension, the service life of the steel wire ropes is shortened, the system ensures that the tension of the two lifting ropes is kept equal in real time, the torque in the lifting ropes is effectively released, the rope adjusting range is greatly increased by adopting a balanced rope mode, the structure is simple, the manufacturing cost is low, the replacement is convenient, the using effect is good, and the.

Detailed Description

The following further describes the embodiments of the present invention.

The tension balancing device for the ultra-deep well double-rope parallel winding type lifting system comprises a lifting rope 1, a wedge-shaped rope ring 2, a untwisted rope clamp 3, a balancing rope 4, a balancer 5 and a lifting container 6; the lower part of the balancer 5 is connected with a lifting container 6, the upper part of the balancer 5 penetrates through two rollers in the balancer 5 through a balancing rope 4 to respectively extend upwards from the left side and the right side of the top end to be connected with a first wedge-shaped rope ring 2, and the second wedge-shaped rope ring 2 and the lifting rope 1 are connected through the unwinding rope clamp 3, so that a U-shaped double-rope parallel winding type lifting system tension balancing system is formed.

In the above embodiment, the balancer 5 is composed of a housing 5-1 and two balancing rollers 5-2 arranged symmetrically with respect to the central axis thereof; the balance roller 5-2 is fixedly connected to the shell 5-1 through a bearing; the balance rope 4 passes through the balancer 5 and bypasses the two balance rollers 5-2 to realize tension balance.

In the above embodiment, the untwisting rope clip 3 is composed of a rope clip sleeve 3-1 and a thrust bearing 3-4 arranged therein, a rope clip 3-3 sleeved on the rope clip sleeve 3-1, and a bolt 3-2 for connecting the rope clip sleeve 3-1 and the wedge-shaped rope ring 2 or connecting the rope clip 3-3 and the wedge-shaped rope ring 2.

In the above embodiment, the tension balancing system is that two lifting ropes 1 are respectively connected to two ends of a balancing rope 4 through an unwinding rope clip 3, and the tension of the balancing rope 4 is equal everywhere according to the mechanics analysis, so that the tension of the two connected lifting ropes 1 is ensured to be the same as the tension of the balancing rope 4; when rope length is poor when two lifting ropes 1 appear, shorter lifting rope 1 tension is bigger than normal, longer lifting rope 1 tension is littleer, and shorter side lifting rope 1 will stimulate balanced rope 4 and remove to longer side lifting rope 1 under the pulling force effect this moment, compensates the rope length of both sides poor, finally keeps the tension of the lifting rope 1 of both sides equal.

In addition, the untwisting rope clamp between the lifting rope 1 and the compensation balance rope 4 is equivalent to a rotating pair, so that the torque on the lifting rope 1 is effectively released, and the tension balance of double-rope parallel winding is realized.
