The invention relates to an elevator brake release system which comprises an electric brake release device and a brake, the elevator brake release system further comprises a speed measuring module and a pressure regulating module, the output end of the electric brake release device is connected with the brake through the pressure regulating module, and the speed measuring module is connected with the brake through the pressure regulating module. The speed detection module is used for detecting the real-time speed of an elevator after brake release and outputting a real-time speed signal to the voltage regulation module; and the voltage regulating module is used for regulating the brake voltage output to the brake by the electric brake releasing device according to the real-time speed signal. Through the application, the problems that the sliding speed is too high, accidents are easy to occur and panic of passengers in a lift car is caused after a main engine band-type brake is loosened, and the leveling precision is poor and not safe enough due to the high speed during stopping in the prior art are solved, the operation is simple, the sliding speed is stable after the brake is loosened, the leveling precision is high, and the safety is high. Therefore, the elevator taking safety and taking experience of passengers are improved.

    本申请涉及一种电梯松闸系统,包括电动松闸装置和制动器,所述电梯松闸系统还包括测速模块以及调压模块,所述电动松闸装置的输出端经由所述调压模块与所述制动器连接,其中:所述测速模块,用于检测电梯松闸后的实时速度并向所述调压模块输出实时速度信号;所述调压模块,用于根据所述实时速度信号调节所述电动松闸装置向所述制动器输出的抱闸电压。通过本申请,解决了相关技术中主机抱闸松开后溜车速度过快,易发生事故和引起轿厢内乘客的恐慌,停下时因速度快而导致平层精度较差且不够安全的问题,操作简单,松闸后的溜车速度稳定,平层精度较高,从而提高了乘客乘坐电梯的安全性和乘坐体验。
