Abstract

The invention discloses a safety elevator working method and an elevator with a safety interlock. The safety interlock is composed of L-shaped bolt rods, a transmission rod with transmission gears, guide rail locking frames, support frames, a motor drive gear and an interlock drive motor. The safety elevator working method is achieved through the safety interlock. The phenomenon that when the elevator is in the stop state, an elevator car is locked and cannot move before or after a car door is opened is achieved; and when the elevator car moves or the car door does not reach a hall door area, the car door is locked and cannot be opened. The safety elevator working method and the elevator with the safety interlock have the beneficial effects of being capable of achieving interlock control, high in reliability, easy to implement, maintain and manage.

Description

technical field [0001] The invention relates to a safe elevator working method and an elevator with a safety interlock device, belonging to the field of elevator safety technology or electromechanical. Background technique [0002] At present, the safety protection devices at the entrance of the elevator door mainly include the following types: [0003] 1. Contact protection device (contact door entrance safety protection device composed of door touch panel, control lever, micro switch and limit switch) [0004] 2. Photoelectric protection device (non-contact type) [0005] 3. Electromagnetic induction protection device (non-contact type) [0006] 4. Ultrasonic monitoring device (non-contact) [0007] 5. Infrared light curtain protection device (non-contact type) [0008] The above technologies basically belong to the detection control technology, which mainly installs detection sensors at the relevant positions of the equipment. When the car door is detected to be open,...
