Abstract

A compensation method for a multi-rope winding type elevator steel wire rope synchronous compensation wheel is characterized in that in the process of lifting a container, when the length of one steel wire rope is shortened and the stress is heavier during lifting, the length of the other steel wire rope is lengthened and the stress is relieved, a wheel body and a wheel shaft rotate in the direction of lengthening the length of the steel wire rope and relieving the stress through a lever principle, so that two steel wire ropes are stressed in a balanced manner; the tension of the steel wire rope of the multi-rope winding type hoister can be flexibly and conveniently balanced and asynchronously compensated; the weight is lighter than that of a hydraulic tension balance system of the multi-rope friction type hoister, and the adjusting capacity is larger than that of the tension balance system; because the lever principle is relied on, the tension of the steel wire ropes on two sides can be compensated to be the same by means of the rotation of the compensation wheel around the mandrel, and the mechanism is safe and reliable.

Description

Compensation method for wire rope synchronous compensation pulley of multi-rope winding hoist

technical field

The invention relates to a steel wire compensating wheel of a mine hoist, in particular to a compensation method for synchronously compensating the steel wire rope of a multi-rope winding hoist.

Background technique

At present, the mine hoist is one of the important and key equipment in the mine, mainly used in coal mines, metal mines and non-metallic mines, hoists and decentralized personnel to lift coal, ore, and transport materials and equipment. It is an important means of transportation to connect the well and the underground. It occupies a very important position in the mine and is an important equipment of the mine. The mine hoist is developed from the hand potter's wheel. With the development of science and technology, the hoist has developed from the KJ type to the JKA type, and from the XKT type, XKTB type to the current JKZ type and the new multi-rope winding type. Mine hoist.

The multi-rope winding mine hoist uses two wire ropes to simultaneously lift a hoisting container, so the diameter of the wire rope can be effectively reduced, making it more suitable for ultra-deep shaft hoisting. However, because two wire ropes are used to simultaneously lift a hoisting container, there are Tension balance problem of wire rope on the same lifting container. At the same time, the multi-rope winding hoist has to be wound synchronously on the drum because the wire rope is wound synchronously. However, in reality, the winding of the wire rope may be asynchronous, for example, one wire rope on the same hoisting container occurs earlier than the other. If there is no corresponding synchronization device, it will cause the lifting container to tilt in the shaft, causing serious overload of one wire rope while the other wire rope is not under force, loose rope, etc. Consequences; in view of the above reasons, the lengths of the two steel wire ropes on the existing lifting container are different, causing a serious overload of the steel wire rope, and the other steel wire rope is not under force to loosen the rope, which will cause the lifting container to tilt in the shaft. A compensation method for the synchronous compensation pulley of the wire rope of the multi-rope winding hoist is invented.

Contents of the invention

The purpose of the present invention is to overcome the different lengths of the two steel wire ropes on the existing lifting container, causing a serious overload of one steel wire rope, and the other steel wire rope is loose due to no force, which will cause serious consequences for the lifting container to tilt in the shaft. Through reasonable design, a compensation method for the synchronous compensation wheel of the steel wire rope of the multi-rope winding hoist is provided. Because it relies on the principle of leverage and relies on the compensation wheel to rotate around the mandrel, it can compensate for the same tension of the steel wire ropes on both sides, and the mechanism is safe and reliable.

In order to achieve the above object, the present invention adopts the following technical scheme: a compensation method for the wire rope synchronous compensation wheel of a multi-rope winding hoist, the multi-rope winding hoist wire rope synchronous compensation wheel is clamped by a wheel shaft and a wheel body It consists of a device, a wire rope, a container, a rope outlet hole, and a wheel frame plate; two symmetrical wheel frame plates are arranged in the middle above the container, and a wheel body is arranged between the two wheel frame plates. The two wheel frame plates correspond to the center of the wheel body. Leave a hole, and set the wheel shaft in the hole; set the wire rope in the wheel groove of the wheel body, and reserve rope holes on both sides of the wheel groove; The rope ends of the steel wire ropes are respectively set in the rope hole and the gripper; two steel wire ropes are respectively set in the wheel grooves, and the two steel wire ropes are wound opposite to each other for at least three turns; when the two steel wire ropes of the hoist are lifting the container, different lengths cause tension When changing, the wheel body and the wheel shaft use the principle of leverage, and the wheel body will rotate around the mandrel towards the side where the force is greater, so that the two steel wire ropes are balanced; in the process of lifting the container, the length of one steel wire rope becomes When the short stress is heavy, the length of the other steel wire rope is lengthened and the stress is lightened. The wheel body and the wheel shaft are through the principle of leverage, and the wheel body turns to the direction of lengthening the length of the steel wire rope to reduce the stress, so that the two steel wire ropes are balanced.

The beneficial effects of the present invention are: it can flexibly and conveniently balance the tension of the wire ropes of the multi-rope winding hoist and compensate for the asynchronousness; the weight is lighter than the hydraulic tension balance system of the multi-rope friction hoist, and the adjustment ability is better than that of the tension The balance system is large; because it relies on the principle of leverage, relying on the compensation wheel to rotate around the mandrel, it can compensate for the same tension of the wire ropes on both sides, and the mechanism is safe and reliable.

The width of the compensation wheel can be designed according to the actual needs. When the width needs to be increased to increase the adjustment capacity, its influence on its own weight is not as obvious as the tension balance system of the multi-rope friction hoist.

The wire rope synchronous compensating pulley adopts a helical rope groove matching the diameter of the wire rope processed on the wheel shell, and the number of turns of the rope groove is calculated according to the specific parameters of the multi-rope winding hoist, so as to ensure normal winding and occurrence After the wrong winding emergency brake stops, each steel wire rope has at least 1.5 winding ropes on the wheel. The two steel wire ropes on the same lifting container are respectively installed on both sides of the compensation wheel. After winding several turns on the compensation wheel, the wire rope ends are installed on the web plate of the compensation wheel with a clamp.

There is a mandrel in the center of the compensation wheel, and the lifting container is suspended on the mandrel, and the compensation wheel can rotate around the mandrel, so that when the tension in the two wire ropes is different or the tension is different due to the length of the wire rope, according to the principle of leverage, the compensation wheel will revolve around the center The shaft rotates toward the side where the force is greater, so that the steel wire rope on the side with greater force becomes longer, and the force therein is reduced until the tension of the steel wire ropes on both sides is equal.
