Such as a mining friction hoist or a construction elevator. The former is realized by winding a single steel wire rope, so that the borne load is limited, and if the lifting height or the moving distance is long, the diameter of the winding drum needs to be designed to be large; although the latter can realize the simultaneous bearing of a plurality of ropes and the lifting height is not limited by the winding width of the winding drum, the wrap angle formed by the steel wire ropes placed on the friction wheel is about 180 degrees generally, and if other structures are adopted, the wrap angle of not more than 270 degrees can be realized at most. Based on an Euler formula, the tension difference (effective load) generated at two ends of the steel wire rope is 2-3, and the steel wire rope can be used for lifting load limitation.
The utility model is a driving mode which is provided on the basis of combining the two types, namely, the lifting requirements of super-long height and large tension difference (effective load) can be realized by using one steel wire rope without a winding drum with a large diameter; the reduction of the diameter of the winding drum directly reduces the rotational inertia of the equipment, so that the equipment is more suitable for quick start and stop operation.
