摘要
近几年超高层建筑物日益增加,人们对超高层建筑物的电梯使用效率提出了更高的要求,当前仅靠增加电梯速度和轿厢载重的一台电梯一个轿厢的多台电梯群控的方法,已不能满足超高层建筑物运输乘客的需求。一种在一个井道运行2个独立轿厢的双子电梯应用而生。如何避免在同一个井道内2个轿厢在运行时发生碰撞,确保电梯运行安全,是双子电梯应该解决的关键问题。针对双子电梯双轿厢运行的安全性问题,采用冗余性的位置探测技术,实时探测井道内2个轿厢之间的相对距离,设定2个轿厢运行的最小安全距离;同时,根据国家电梯制造标准要求,在电梯控制系统设置曳引机紧急制停系统、安全钳保护系统等多重安全保护措施,确保双轿厢在极端异常情况下电梯能够停止运行,避免2个轿厢相撞。实践表明,该技术措施行之有效。
In recent years, with the increasing of super high-rise buildings, people have put forward higher requirements on the elevator efficiency of super high-rise buildings. The group control method of increasing the elevator speed and car load of one elevator and one car of multiple elevators can not meet the needs of super high-rise buildings to transport passengers. A twin elevator application with two independent cars running in a well was desiged. How to avoid the collision between two cars in the same well and ensure the safety of the elevator operation was the key problem that should be solved by the twin elevator. Aiming at the safety problem of the operation of the double car of the twin elevator, the redundant position detection technology was used to detect the relative distance between the two cars in the shaft in real time, and the minimum safe distance of the two cars was set. At the same time, according to the requirements of national elevator manufacturing standards, multiple safety protection measures such as emergency stop system of tractor and safety clamp protection system were set up in the elevator control system to ensure that the elevator could stop running under extreme abnormal circumstances and avoid the collision of two cars.Practice shows that the technical measures proposed are effective.
