Abstract

The invention provides a friction type mine hoisting system which comprises a friction wheel, a drive unit, a first hoisting container, a balance weight or a second hoisting container and carbon fiber ropes. The drive unit is connected with the friction wheel to drive the friction wheel to rotate. The carbon fiber ropes are provided with first ends and second ends, wherein the first ends are connected with the first hoisting container, and the second ends wind around the friction wheel to be connected with the balance weight. According to the friction type mine hoisting system, the carbon fiber ropes are adopted to replace the existing steel wire ropes, carbon fibers are new materials with excellent mechanical properties, the specific gravity of the carbon fibers is less than one-fourth that of steel, the tensile strength of the carbon fibers is 7-9 times that of the steel, the elastic tensile modulus of the carbon fibers is also high than that of the steel, the influences of well depth on load hoisting and service life prolonging of the carbon fiber ropes are far smaller than those of the steel wire ropes, and the use cost of the carbon fiber ropes is low. In addition, the friction type mine hoisting system is needless to be provided with tail ropes, and therefore system configuration is simplified.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a friction type mine hoisting system. Background technique [0002] Mine hoisting system is one of the commonly used hoisting systems in mines. Mine hoists in the related art usually use wire ropes to pull the first hoisting container. However, the steel wire rope of the mine hoist in the related art has the problems of heavy weight, small carrying capacity, and short service life, and there is a demand for improvement. Contents of the invention [0003] The present invention is based on the inventor's discovery of the following facts and problems: the mine hoisting system in the related art adopts wire rope traction, and the wire rope has a large dead weight, which causes a large load on the driving device and reduces the efficiency of the hoisting system; when the mine is deep, Practice has proved that the hoisting wire rope has a short life, frequent replacement, high cost,...
