Abstract
To eliminate frequent abnormal opening of shaft door resulting from shaft door shoe disengaging from sill groove with elevator shaft door under external force, a protection device is designed for this end. The device is equipped with a mandatory mechanical mechanism in tandem with shaft door opening and closing, which pushes the protection device into or out of the working position, i.e., the hook of the device getting into or out of the anti-off device installed on the sill and door pocket. When the shaft door is under external shock, the device can reduce the deformation of the shaft door under the action of the hook, further enhance the strength of the shaft door and prevent the shaft door shoe disengaging from the sill, thus avoiding abnormal opening of the elevator shaft door under external force. This mode is intrinsically safe, which not only eliminates the shaft door shoe disengaging from the groove and prevents abnormal opening of the shaft door due to external force, but also ensures the normal operation of the elevator.关键词
