Abstract

The invention relates to elevator braking equipment, a braking control method and device and a storage medium. The elevator braking equipment comprises a driving module and a plurality of brakes, thedriving module is connected with each brake, under the condition that a power grid power supply loses power, the driving module drives any brake to perform braking action, the driving module drives the other brake to perform a braking action after a preset duration to complete the driving, driving times are updated, and the driving module accumulates the driving times until each brake completes the braking action. According to the elevator braking equipment, all the brakes can conduct braking respectively, the braking torque is generated in advance in the mode that the braking torque is reduced by multiple times, and after preset time is delayed, the other group of brakes generates the braking torque again to conduct superimposed braking; therefore, the rising speed of the braking torque is reduced, the deceleration of a lift car under the condition of power loss is effectively reduced, and the impact degree on passengers is reduced; and meanwhile, abrasion of a steel wire rope and traction wheel parts is weakened, and the service life is prolonged.

Description

technical field [0001] The present application relates to the technical field of elevators, in particular to an elevator braking device, a braking control method, device and storage medium. Background technique [0002] With the increasing popularity of elevators, elevators have become an indispensable means of vertical transportation in daily production and life. Elevator braking is an indispensable part of elevator technology. In the current traditional elevator technology, there are three types of braking devices, namely: speed governor braking, rope clamp braking and brake braking. [0003] During the implementation process, the inventors found at least the following problems in the traditional technology: traditional brake braking has problems such as low service life of equipment. Contents of the invention [0004] Based on this, it is necessary to provide an elevator braking device, a braking control method, a device, and a storage medium that can improve the servi...
