Double-roller linkage winding type lifting system

Abstract

The invention discloses a double-roller linkage winding type lifting system. The double-roller linkage winding type lifting system comprises a first lifting roller and a second lifting roller, and thefirst lifting roller and the second lifting roller are in engaged linkage through an engagement structure on the outer circumference or are in linkage through linkage middleware; the first lifting roller is wound with a first lifting rope, the second lifting roller is wound with a second lifting rope, and the first lifting rope and the second lifting rope are not connected with each other. The double-roller linkage winding type lifting system can increase the energy efficiency ratio of an extradeep well lifting system.

Description

technical field [0001] The invention relates to the field of mine equipment, in particular to a double-drum linkage winding lifting system. Background technique [0002] There are two kinds of existing lifting systems, one is a winding type, and the other is a friction type. For the winding type, in ultra-deep wells with a depth greater than 1200m, with the increase of well depth, the proportion of hoisting rope's own weight in the hoisting load increases rapidly, and the hoisting payload becomes smaller and smaller, and the energy efficiency ratio of the hoisting system becomes more and more Low. For the friction type, it must use the tail rope. When the depth is deeper, the tail rope will be longer, and the weight of the tail rope will be greater. When the depth of the mine is greater than 1000m, the weight of the hoisting rope itself will increase the load. The proportion of the tail rope increases sharply, the torque output by the drum is almost all used to carry the w...

Problems solved by technology

For the winding type, in ultra-deep wells with a depth greater than 1200m, with the increase of well depth, the proportion of hoisting rope's own weight in the hoisting load increases rapidly, and the hoisting payload becomes smaller and smaller, and the energy efficiency ratio of the hoisting system becomes more and more Low

For the friction type, it must use the tail rope. When the depth is deeper, the tail rope will be longer, and the weight of the tail rope will be greater. When the depth of the mine is greater than 1000m, the weight of the hoisting rope itself will increase the load. The proportion of the tail rope increases sharply, the torque output by the drum is almost all used to carry the weight of the tail rope, and the lifting payload decreases sharply, that is, the energy efficiency ratio is also very low

Therefore, none of the existing hoisting systems can solve the problem of low energy efficiency ratio in the ultra-deep well hoisting system
