Description
Technical Field
The invention relates to the technical field of elevator landing doors, in particular to a screw type driving landing door with controllable door opening width.
Background
The elevator landing door is an elevator door arranged on each floor and corresponds to the elevator car door. Among the prior art, generally be through the switching of sedan-chair door drive layer door, when the sedan-chair door reachd current floor, the short circuit is carried out to sedan-chair door lock, and all layer doors are in dangerous state this moment, can all be opened, and ordinary people is not familiar with elevator equipment, may cause the incident. For example, children, old people and drunk people in families may be misused and mistakenly open the landing door, thereby causing a falling accident.
The layer door can be opened from the outside, and non professional can use specific key to open layer door, when opening, only connects through a latch hook between the two-layer door. When the latch hook is opened, if the force is too large, the door opening width is too large, and a person opening the door can fall into a hoistway, so that potential safety hazards can be caused;
in addition, the bottom of the landing door moves above the sill by using the sliding block, and if violent impact is met, the door plate can be separated from the sill, so that impact personnel fall into a hoistway.
The present invention has been made based on such a situation.
Disclosure of Invention
The screw type driving landing door aims to overcome the defects of the prior art, is simple in structure, convenient to install, high in safety, capable of controlling the door opening width of the landing door during maintenance, free from separation when the landing door is impacted, capable of effectively preventing personnel from falling, low in cost and capable of improving the material utilization rate.
The invention is realized by the following technical scheme:
the utility model provides a controllable screw drive layer door of width of opening door, thereby removes the layer door that opens and shuts including ability, the top of layer door is equipped with the drive assembly that drive layer door opened and shut, drive assembly includes the driving source, the output of driving source is connected with drive screw, the last a plurality of drive nuts that is equipped with of drive screw, drive nut fixes the upper portion at layer door. The driving source drives the screw rod to rotate, so that the driving nut moves along the driving screw rod, and the opening and closing of the landing door are driven.
Thus, the landing door can only be driven by a driving source and cannot be directly opened; and because the driving nut moves slowly and gradually along the movement of the driving screw rod, the driving nut can also stay at any position of the driving screw rod, so that the door opening speed and the door opening width can be controlled, namely, the landing door is opened gradually when the landing door is opened, and even if the landing door is violently impacted, the landing door cannot be opened greatly, so that the safety can be ensured, and the personnel can be prevented from falling off because of impacting and passing through the landing door.
