Problems solved by technology
When the elevator is running normally, there is generally no safety problem, but when the elevator does not stop at the normal floor stop position, if the door can still be opened, there will be a safety hazard
If the elevator stops between two floors, if the people in the car can open the car door, they may be trapped in the elevator shaft. If the elevator is not in place, the floor door can be opened, and there will be a risk of falling

The invention provides an elevator safety device. The elevator safety device comprises an acting connecting plate and a flap rotating recess mechanism, wherein the acting connecting plate comprises a short double-acting connecting plate fixed to a floor door and a long double-acting connecting plate fixed to a lift car door; the flap rotating recess mechanism comprises a touch assembly and a recess assembly, the recess assembly is arranged on the same side of the acting connecting plate, the touch assembly is arranged on the side opposite to the acting connecting plate, and a limit part is arranged on the recess assembly; when the touch assembly is in contact with the recess assembly, the limit part is positioned in a first position; and when the touch assembly is separated from the recess assembly, the limit part is positioned in a second position capable of blocking the movement of the acting connecting plate. The door is opened and closed under the control of a lift car clamping mechanism. When an elevator does not arrive, both the lift car door of the elevator and the floor door of the floor are positioned in a locked state and cannot be opened, so that the purpose of ensuring elevator safe running is achieved, and the event of elevator lift car movement after the door is opened and the accidental event of a door system are avoided.
Description
technical field [0001] The invention relates to an elevator safety device, in particular to an elevator safety insurance device. Background technique [0002] In elevator installations that meet modern safety requirements, the elevator car and the elevator shaft are usually equipped with automatically operable sliding doors. Depending on the size of the doorway, it can be a single sliding door with one or more leaves, or a double sliding door with a central opening. In addition, various doors can also be combined in different elevator installations. When the elevator is running normally, there is generally no safety problem, but when the elevator does not stop at the normal floor stop position, if the door can still be opened, there will be a safety hazard. If the elevator stops between two floors, if the people in the car can open the car door, they may be caught in the elevator shaft, and if the elevator is not in place, the floor door can be opened, and there will be a ...
