Today, Passenger Elevator Factory Shares The Benefits Of Designing Elevator Spaces
1. Opening and closing of car door. The car door is a device for opening or closing the car, and also a device for opening and closing the operating floor door. Under normal circumstances, the car door can only be opened when the car stops at the floor. Its opening and closing are usually driven by a door opener. The car door is connected to the landing door through a special device and synchronizes the two to open and close the door. In order to prevent the passengers from being injured during the door closing process, the maximum closing speed does not exceed 0.3m / s, the maximum blocking closing force does not exceed 150n, and the maximum kinetic energy at the average closing speed does not exceed 10j; the door will automatically restart when it encounters passengers Open; without the car door fully closed, the elevator cannot be started or kept running. Under special circumstances, near the landing, when the car stops moving and the power of the door opener is cut off, the car door and the landing door connected to it can be opened (or partially opened) with a force not greater than 300n.
2. The role of door locks. The door lock is installed on the landing door and is a device that keeps the landing door closed. When locking the landing door, using a force of less than 300n in the direction of opening the door will not reduce the locking efficiency of the door lock, and using a force of less than 1 000n will not cause the locking element to permanently deform. The door lock is anti-dust, anti-vibration and easy to check. Under normal circumstances, the door lock can only be opened by the car door. In special cases, it can be opened by a special person with a key. In addition to the mechanical device, the door lock also has an electrical device, that is, a safety contact that keeps synchronously closed or opened with the landing door. It is responsible for providing the control cabinet with information on whether the landing door is closed. There is a same set of safety contacts on the car door. These safety contacts are connected in series with the safety contacts of other important parts in the safety circuit. As long as there is a group of safety contacts that are not closed, the elevator cannot be powered on.
