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.

    本申请涉及一种电梯制动设备、制动控制方法、装置和存储介质。其中,电梯制动设备,包括驱动模组和多个制动器;驱动模组与各制动器连接;在电网电源失电的情况下,驱动模组驱动任一制动器进行制动动作;驱动模组在间隔预设时长后驱动另一制动器进行制动动作以完成本次驱动,并更新驱动次数;驱动模组累加驱动次数直至各制动器均完成制动动作。上述电梯制动设备可以使得各组制动器分别进行制动,制动力矩以减少数倍的形式提前产生,并延时预设时长后另一组制动器再产生制动力矩进行叠加制动。从而降低了制动力矩上升的速率,进而有效的降低了失电情况下的轿厢减速度,降低了对乘客的冲击度。同时,减弱了钢丝绳及曳引轮部件的磨损,提高了使用寿命。
