Abstract

The invention provides an elevator traction system and a control method thereof. The elevator traction system involves a machine base, a traction wheel device and a traction power source, wherein thetraction wheel device is arranged on the machine base; the traction wheel device comprises an outer ring wheel and an inner ring wheel which are coaxially arranged, and the radius of the outer ring wheel is larger than the radius of the inner ring wheel; and the traction power source is mechanically connected with the outer ring wheel. Due to the fact that the traction wheel device adopts the ringwheels with different diameters to drive a lift car to do lifting motion, the driving force of the lift car is reduced, waste of the electric energy is reduced, and then the cost of an elevator is reduced. Meanwhile, in regard to a large-load lift car, a counterweight structure can be omitted, the unnecessary driving electric energy of the elevator can be reduced, so that the cost of the elevatoris further reduced, and the running performance of the elevator is optimized.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an elevator traction system and a control method thereof. Background technique [0002] With the continuous development of society, there are more and more multi-functional commercial and residential buildings. As a vertical transportation tool, elevators are widely used in large-capacity specifications and become an indispensable transportation in people's life and work. tool. [0003] At present, the counterweight of the elevator is generally the sum of the empty weight of the car and the rated half-load, as well as the matching guide rails and guide rail brackets. When the elevator is a freight elevator such as a car, these mechanical parts of the counterweight function, especially the elevator at the lower floor station, will enter the deceleration state just after the running speed reaches the rated speed. At this time, the traction motor only has starting and d...
