介绍了SC型施工升降机的吊笼与传动装置传统的连接方式,说明其缺陷,分析其原因,并针对该问题设计了新型的连接方式并将蝶形弹簧应用到此技术上。该技术不仅改善了由于以往连接方式的缺陷导致整机运行时振动大、启动和停止瞬间有较强的抖动等问题。也为蝶形弹簧在起重行业的应用做出了创举先例,供同行业人士参考。 This paper introduces the traditional connection between the cage and transmission of SC construction lifts, explains its defects, analyzes its causes and designs a new connection method to this problem and applies the butterfly spring to this technique. The technology not only improves the vibration of the whole machine due to the defects of the past connection modes, but also has strong jitter in the starting and stopping moments. But also for the application of the butterfly spring in the lifting industry has made precedent for the same industry for reference.
