The invention discloses a control method of electronic safety tongs, the electronic safety tongs comprise two sets of safety tongs, two guide rails and a control box, each set of safety tongs is installed on one guide rail, and the two sets of safety tongs are electrically connected with the control box; each set of safety tongs comprises a safety tongs body (1), a pin roller (2), a suction cup (3), an electromagnet (4), a safety tongs rotating plate (5), a spring (6) and a safety tongs wedge block (7). The control method of the electronic safety tongs comprises the following actions of a power-on reset process, a braking action process, safety tongs releasing and resetting, electromagnet fault protection maintaining and power-off time delay. According to the method, the sucker is low in power consumption and reliable in suction and release, the control loop has a self-detection function, and the sucker control loop is connected in series with an overspeed signal to ensure that the safety tongs act when overspeed occurs.
本发明公开了一种电子安全钳的控制方法,所述电子安全钳包括两组安全钳、和两根导轨和控制盒,每一组安全钳分别安装在一根导轨上,两组安全钳与控制盒电连接;每一组安全钳包括安全钳钳体(1)、滚柱(2)、吸盘(3)、电磁铁(4)、安全钳旋转板(5)、弹簧(6)和安全钳锲块(7);所述电子安全钳的控制方法包括以下动作:上电复位过程、制动动作过程、安全钳释放及复位、维持电磁铁故障保护和断电延时。该方法使吸盘保持功耗小、吸合可靠、释放可靠、控制回路有自检测功能、吸盘控制回路与超速信号串接,确保安全钳超速即动作。
