Problems solved by technology

[0002] At present, the safety protection measures for elevators are mainly to install detection switches at relevant positions of the equipment. When the car door is detected to be opened, the system cannot send the car movement signal. Only when the car door is detected to be closed, the system sends the car movement signal. At this time, the elevator car can rise or fall; but if any part of the elevator host or drive system on which the safe movement of the elevator depends fails and fails, the car may move unexpectedly, which will also cause accidental injury to passengers serious consequences of the accident

Abstract

The invention discloses a safety protection mechanism for accidental moving of an elevator car. The safety protection mechanism comprises a triggering device, an executing device and a linking device, wherein the triggering device is used for recognizing an opening state of a door of the elevator car; the executing device is used for immediately locking the elevator car when accidental moving happens in the unclosed state of the door of the elevator car; the linking device is used for linking the triggering device and the executing device; and the triggering device adopts a mechanical triggering structure, the executing device adopts a locking block type locking structure, and the linking device adopts an electrical control structure. The safety protection mechanism can timely detect whether accidental moving happens to the elevator car and can immediately take safety protection measures to lock the car when the safety protection mechanism detects that accidental moving happens to the elevator car, so that the mechanism has important significance in protecting safety of elevator equipment and personal safety of a passenger; and particularly, the safety protection mechanism has the advantages of simple structure, safety, reliability, convenience and flexibility in mounting and the like, and has an obvious practical value in improving the safety of a conventional elevator.
