Lift type driving device for elevator

Abstract

The invention discloses a lift type driving device for an elevator, and relates to the technical field of elevator equipment. The lift type driving device includes a motor, a bearing plate and a magnetic powder brake. An output shaft of the motor is fixedly provided with a driving pulley, and the motor is fixedly installed on the lower surface of the bearing plate through a first connecting plate;a connecting cylinder penetrates through the middle part of the bearing plate, and a first through hole is formed in the connecting cylinder; and a connecting ring is fixedly installed on the top endface of the connecting cylinder, and a second through hole is formed in the connecting ring. According to the lift type driving device, the driven pulley is driven to drive brake shaft sleeves of a step sleeve, the connecting cylinder, the connecting ring and the magnetic powder brake to rotate, so that a screw nut rotates and rises and falls in the axial direction of a screw rod; finally, the brake of the screw nut on the screw rod is realized by controlling the magnetic powder brake; and due to the process, the lifting and falling and brake stability of the elevator driving device are effectively ensured, the risk of people riding is reduced, and the comfort of people riding is improved.

Description

technical field [0001] The invention belongs to the technical field of elevator equipment, in particular to an elevator driving device. Background technique [0002] Nowadays, elevators have become a necessary facility for high-rise buildings, providing people with great convenience. However, the comfort of elevator riding has become the focus of attention. The stability of the lift car and the braking performance determine the detailed quality of the elevator; especially for vulnerable groups such as the elderly and patients, the operating quality of the elevator is particularly important. [0003] Existing elevators have a strong sense of frustration in operation, and the feeling of weightlessness is obvious, which brings people a very bad experience, and the lifting drive device of the elevator car determines the quality and comfort of the elevator operation; The lifting drive device is used to improve the stability of elevator operation and braking as well as the comfor...

Problems solved by technology

[0004] The object of the present invention is to provide a lifting type driving device for an elevator, which drives the driven pulley through the motor to drive the step sleeve, the connecting sleeve, the connecting ring and the brake bushing of the magnetic powder brake to rotate, so that the screw nut Occurs self-rotation, and lifts along the axial direction of the screw; finally, the braking of the nut on the screw is realized by controlling the magnetic powder brake, which solves the problem of poor lifting and braking stability of existing elevators and poor ride comfort The problem
