Abstract
An elevator lifting prevention apparatus is disclosed. The elevator door lifting device according to an embodiment of the present invention is located below the ground of the elevator hall when the elevator door is closed and moves to the elevator silo when the elevator door is opened so as to prevent fall of the passenger plate; And a spring for moving the fall-prevention plate to the elevator silo by an elastic force, wherein one of the edges constituting the fall-prevention plate includes a guide plate attached to the lower end of each of the elevator doors and extending downward, And the movement of the fall prevention plate is guided by the spring in which an elastic force acts in a direction perpendicular to the moving direction of the guide plate and the elevator door as the elevator door is opened and closed .
Description
An elevator according to an embodiment of the present invention is a device for preventing a person from falling into the elevator. When an elevator door is opened without an elevator chamber reaching the door, passengers accidentally enter the elevator silo, The present invention relates to an elevator lifting prevention apparatus.
Sometimes an elevator door opens even though the elevator chamber has not arrived behind the door. In this case, many people are being sacrificed due to the accident that occurs when the user accidentally enters the silos.
In 2013, accidents occurred at 0.0177% in elevators and 0.0133% in 2014, and the incidence of accidents is decreasing every year, but there are still dozens to hundreds of accidents.
Although the invention relating to the fall prevention in the conventional elevator has been filed, a technique against the case in which the door is opened even if there is no chamber due to a malfunction has not been released yet.
A related prior art is Korean Patent Laid-Open Publication No. 20-1998-0014270 (entitled: Lift-up Hall Collapsible Prefabricated Safety Footrest, Open Date: 1998. 06. 05).
An object of an embodiment of the present invention is to provide an elevator lifting prevention device capable of preventing an accident that a door is opened and a passenger falls due to an elevator not arriving.
According to another aspect of the present invention, there is provided an elevator lifting device for an elevator, the elevator door being located below a floor of an elevator hall when the elevator door is closed, and moving to an elevator silo when the elevator door is opened, A fall prevention plate preventing fall; And a spring for moving the fall-prevention plate to the elevator silo by an elastic force, wherein one of the edges constituting the fall-prevention plate includes a guide plate attached to the lower end of each of the elevator doors and extending downward, And the movement of the fall prevention plate is guided by the spring in which an elastic force acts in a direction perpendicular to the moving direction of the guide plate and the elevator door as the elevator door is opened and closed .
The fall-down device of the elevator according to an embodiment of the present invention further includes a fall prevention case which is fixed under the ground of the elevator hall and in which the fall prevention plate is located when the elevator door is closed, Is connected to the fall prevention plate and the other end is connected to the fall prevention case.
The lifting device of the elevator according to an embodiment of the present invention includes a load cell located on an upper portion of the fall prevention plate; And a notification unit for generating a notification when a load is detected on the load cell.
Preferably, the guide plate includes a roller in contact with the fall prevention plate, and movement of the fall prevention plate is performed by contact rotation of the roller.
An embodiment of the present invention relates to an elevator door which is located in a hall of an elevator when the elevator door is closed and moves to the elevator silo by the restoring force of the spring when the elevator door is opened, A fall prevention device is provided.
