The invention discloses an electromagnetic induction starting type elevator bearing room emergency descending control device, and belongs to the technical field of construction machinery. The device is mainly composed of a magnet block, an induction coil, a micro-ammeter, a micro-ammeter pointer, a contact, a micro-current system wire, a power supply, an electromagnet system wire, an electromagnetbinding post, an electromagnet, an electromagnet box, a control pin, a control pin sleeve, a control bolt, a control bolt front gear, a spring, a control bolt rear gear and a foot margin. When a bearing room drops suddenly, the coil rapidly cuts magnetic lines of force to generate strong micro-currents, so that an electromagnet circuit is conducted. The electromagnet sucks the control bolt, and the front portion of the control pin separated from the control bolt slides into an elevator shaft under the action of gravity. The bearing room which suddenly descends from the upper side in the elevator shaft is clamped by the control pin. The device is convenient to manufacture, can be installed on each floor of an elevator room and is suitable for guaranteeing safe operation of elevators.
一种电磁感应启动式电梯承载间急降控制装置,属于建筑机械技术领域。主要由磁铁块,感应线圈,微电流表,微电流表指针,触点,微电流系统导线,电源,电磁铁系统导线,电磁铁接线柱,电磁铁,电磁铁箱,控制销,控制销套,控制栓,控制栓前档,弹簧,控制栓后档,地脚组成。当承载间急降时,线圈快速切割磁力线会产生较强微电流,使电磁铁线路导通;电磁铁吸引控制栓,脱离控制栓的控制销靠重力其前部滑落到电梯井内;电梯井内从上面急降下的承载间被控制销卡住。便于制作,可安装在电梯间各层,适用于保障电梯安全运行。
