基于多组并联控制的高层建筑遇险循环链梯研究

为了解决居住在高层建筑中的人们遇险后安全疏散的问题,研究出一种新颖的无动力链梯逃逸系统。在没有电力资源的情况下,既要解决循环链梯缓降速度,实现平滑控制的问题,又要解决系统长期处于闲置状态,而不影响其可靠性的问题。提出了循环链梯缓降速度多组并联控制的方案;采用液压式并联控制机构,很好地解决了链梯缓降速度的平滑控制及其可靠性的问题;并成功地研制出循环链梯的试验装置,经实际的性能测试表明,具有启动负荷小、运行平稳、工作可靠的特点。

Study on Circular Chain Ladder for High Building in Emergency Based on Multiple Sets Parallel Control Technology

In order to safely evacuate people living in high building in emergency, a new escape system, um- powered circular chain ladder, is studied. When there is on dectrical power, slaw descending control of circular chain ladder as well as to assure the reliability in use when set aside far a long time has to be solved. An approach to slowdown the descending speed of circular chain ladder based on multiple sets parallel control technology is put forward, in which hydraulic pressure parallel control structure is adopted. This approach well solves smooth control of the chain ladder and its reliability. The test device is also developed. Results of performance tests show that its initiating load is small, and operation is steady and reliable.
