Abstract
The invention relates to a lift safe operation automatic locking device. An electromagnet (2), a reset spring (3), a positioning rod (4), a positioning rod retractable hole (5) and a blocking iron block (6) are all installed in a device outer shell (1). The electromagnet (2) is installed on the rear portion of the device outer shell (1). The reset spring (3) and the positioning rod (4) are installed in the middle of the device outer shell (1), and the positioning rod (4) stretches and retracts through the positioning rod retractable hole (5) in the middle of the blocking iron block (6) while conducting positioning. The whole automatic locking device is installed in an installation wall (7). Normally, the blocking iron block (6) and the installation wall (7) are in the same plane under the action of the electromagnet (2). When a failure happens, the electromagnet (2) loses power, and the blocking iron block (6) stretches out of the installation wall (7) and prevents a lift from operation, so that the lift is safely locked.
