摘要
附着升降脚手架广泛应用在高层建筑施工中,当其不同步升降时机位荷载将重新分配,可能使某段架体或某些机具超载,构成安全隐患。依据一种基于测量电动葫芦电机转数的同步控制方法,基于微动开关对电机的转速测量,间接计算脚手架升降的高度差,从而实现各个机位的同步运行。在此基础上利用AT89C52单片机开发出同步控制装置。经过试验和实际运行结果表明,能够达到附着升降脚手架同步升降的目的。
Attached self-lifting scaffolds are widely used in construction of high buildings.Machine position load will re-distributed when attached lifting scaffolding are lifted asynchronously,some members or some machine parts will be overloaded and form incipient faults.A study on measuring the rotational speed of motor was introduced in this paper,which calculated the lifting length difference by detecting the rotational number of motor and then synchronous lifting and declining solution of different machine position were achieved.Based on the principle,the synchronous device was designed using AT89C52 micro chip computer.The operational result shows that attached self-lifting scaffolds can run synchronously with this device.
