The invention relates to the technical field of elevator control, in particular to a protection device for accidental movement of an elevator car and a control method.The device comprises a first brake, a second brake and a brake control module, and the first brake and the second brake are both connected with the brake control module. The brake control module is used for detecting a brake signal of the first brake, and when the brake signal of the first brake is inconsistent with a preset brake signal, the second brake is controlled to limit the action of a gearless traction machine. The first brake and the second brake are arranged on the gearless traction machine, a first brake signal of the first brake is obtained through the brake control module, and then the obtained first brake signal is compared with a preset brake signal in a preset brake control module; and then the second brake is controlled to limit the gearless traction machine to act according to the comparison result, so that the elevator stops operating, an elevator car is prevented from moving accidentally, and the safety of the elevator passengers is guaranteed.
本发明涉及电梯控制技术领域,具体涉及一种电梯轿厢意外移动的保护装置及控制方法,该装置包括:第一制动器、第二制动器及制动控制模块,第一制动器和第二制动器均与制动控制模块连接,制动控制模块用于检测第一制动器的制动信号,当第一制动器的制动信号与预设制动信号不一致时,控制第二制动器限制无齿轮曳引机动作。通过在无齿轮曳引机上设置第一制动器、第二制动器,利用制动控制模块获取第一制动器的第一制动信号,再将获得的第一制动信号与预设制动控制模块中的预设制动信号进行比较,之后根据比较结果控制第二制动器限制无齿轮曳引机动作使其电梯停止运作,从而防止电梯轿厢产生意外移动,保证乘梯人的安全。
