Description

Lifting system and lifting method for realizing double-code balance and energy conservation of auxiliary vertical shaft

Technical Field

The invention belongs to the technical field of mine hoisting, and particularly relates to a hoisting system and a hoisting method for realizing double-code balance and energy conservation of a secondary vertical shaft.

Background

In underground mining of mines, the auxiliary vertical shaft is used for lifting people up and down, blanking and lifting gangue. In general, auxiliary vertical shaft hoisting is usually a double-drum winch or a multi-rope friction-wheel winch, i.e. so-called double lift. When the winch works, the efficiency is improved and the stress balance of the winch roller is realized. In theory, when the loads on two sides are equal (namely the weight of lifting upwards is equal to the weight of lowering downwards), the winch is stressed in a balanced manner, and the work done by the winch is the minimum. Generally, when the winch is heavy in upward lifting and light in downward lowering, the force borne by the winch is the difference between the two, and the winch works greatly and consumes the most electricity; this will increase the power consumption much more than 500 meters when the deep well is lifted. When the weight of downward lowering is large and the weight of upward lifting is small, the lowering speed of the winch needs to be accelerated; in order to control the lowering speed to keep the lowering speed within a safe allowable range, the old winch mostly adopts friction braking to control the lowering speed, which requires a winch driver to perform manual control adjustment according to experience, and the safety is difficult to guarantee. Most of the advanced winches adopt reverse torque self-balancing control and also need to consume a large amount of electric power.

In fact, during normal production under the well, the number of people going into the well in one shift is equal to the number of people going up the well; the weight of the material being lowered is also substantially balanced with the total weight of the object that needs to be lifted upwards. However, in practice, due to the difference between the time of going up and down the well by workers and the inconsistency between the time of discharging and discharging the waste rock, it is difficult to achieve the equivalent weight of each time of lowering and lifting the winch. And to achieve the purpose that the weight of each lifting and lowering is basically equal, only when the winch is lifted each time, a method of counterweight compensation balance is adopted.
