Problems solved by technology

[0006] When the elevator is closing the door, the light curtain (an invisible light directing device installed on the side of the elevator car door, which will trigger the stop door closing signal when there is an object blocking the light) is triggered and stops closing the door, because the middle door and the outside of the elevator door The door is generally driven by a motor. Since the middle door and the outer door are generally thick and made of metal, if they stop suddenly during the closing process, their inertia will be large. Larger inertia and continue to close, resulting in the phenomenon of people being pinched or impacted

Abstract

The invention relates to an inertia control system for a door machine of a multi-door elevator. Conventional elevator door machines often collide due to inertia. A locking device is installed at a traction belt of the elevator door machine and connected with a logic control unit through a locking device controller. When a driving motor is in a stop state, the logic control unit drives the lockingdevice to lock the door traction belt on the outer side through the locking device controller. When the driving motor needs to be started, the logic control unit drives the locking device to release the door traction belt on the outer side through the locking device controller. By adoption of the inertial control system, mutual collision, caused by the inertia action, of existing elevator doors orcollision to elevator door frames in the opening and closing processes is avoided, and equipment damage caused by frequent collision is avoided. In the case of emergency stop, the inertia control system can eradicate the probability of colliding and crushing injuries, caused by the inertia action of a middle door and an outer door of an elevator, to people.

Description

Technical field [0001] The invention relates to an elevator equipment, in particular to a door machine inertia control system of a multi-door elevator. Background technique [0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or whose inclination angle to the plumb line is less than 15°. The vertical elevator has a car that runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload cargo. It is customary to regard elevators as the general term for vertical transportation vehicles in buildings regardless of their driving methods. According to the speed, it can be divided into low-speed elevators (below 4m / s), fast elevators 4-12m / s) and high-speed elevators (above 12m / s)....
