Problems solved by technology

At present, elevator traction machines with a single traction sheave are generally used in the market. When the size of the hoistway is limited, it is difficult to achieve a smaller structural size. When the elevator is not powered off and the traction machine breaks down, causing the elevator to fall rapidly, the traditional brake cannot perform braking, which makes it difficult to fully guarantee the safety of the elevator. Therefore, a multi-traction sheave, The Appearance of Elevator Traction Machines with Multiple Ways of Braking Is Imminent

Abstract

The invention discloses a multi-wheel driving device and a driving method. According to the multi-wheel driving device and the driving method, a plurality of traction wheels which are arranged separately are adopted, and traction machine stator rotors are placed in the middle positions of the traction wheels, so that the structure size of the traction machine is smaller, the structure is more reasonable, and the reasonable layout of an elevator component in a limited hoistway size is facilitated; a damping speed limiting disc and a strong magnet are arranged, when an elevator is powered off, asharp drop occurs, a metal block on a rotating disc generates an acting force opposite to the rotation of the rotating disc, the rotating speed of the rotating disc is reduced, and the descending speed of the elevator is reduced; an arranged overspeed brake device enables a limiting column to be separated from a rotating core and enter a limiting groove under the effect of the centrifugal force when the elevator abnormally descends, and then the limiting column is quickly clamped through a limiting baffle, so that the rotating core is braked in emergency, then a fixed shaft and a rotating shaft are braked in emergency, the traction wheels stop rotating, the elevator stops descending, and the safety guarantee of the elevator is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of elevator suspension devices; in particular, it relates to a multi-wheel drive device and a drive method. Background technique [0002] Elevator traction machine is the driving device of the elevator. Based on the principle of traction, it completes the function of controlling the elevator car to the designated floor. At present, elevator traction machines with a single traction sheave are generally used in the market. When the size of the hoistway is limited, it is difficult to achieve a smaller structural size. When the elevator is not powered off and the traction machine breaks down, causing the elevator to fall rapidly, the traditional brake cannot perform braking, which makes it difficult to fully guarantee the safety of the elevator. Therefore, a multi-traction sheave, The emergence of elevator traction machines with multiple braking methods is imminent. Contents of the invention [0003] The obj...
