文中叙述了某超高层项目采用的ZSL850内爬式塔式起重机,该机配备创新的支撑梁及自动附墙锁紧机构,可优化其自爬工艺并提高施工稳定性。详细研究了支撑梁及自动附墙锁紧机构的技术参数、结构组成、工作原理、性能特点、实际应用;进行了支撑梁系统的设计与建模,并分析了支撑梁的构成、框架设计及荷载工况。结果表明:支撑梁自动附墙锁紧机构在正常工作和爬升状态下的各项受力情况均符合设计标准,确保了施工的安全性和稳定性。该研究为类似超高层建筑中的塔式起重机应用提供了一定的理论和实践经验。

In this paper,the ZSL850 internal climbing tower crane used in a super-high-rise project is described.The crane is equipped with innovative supporting beams and automatic wall-attached locking mechanism,which can optimize its self-climbing technology and improve construction stability.The technical parameters,structural composition,working principle,performance characteristics and practical application of the supporting beam and the automatic wall-attached locking mechanism are studied in detail.The design and modeling of supporting beam system are carried out,and the composition,frame design and load condition of supporting beam are analyzed.The results show that all the stress conditions of the automatic wall-attached locking mechanism of supporting beam meet the relevant design standards under normal working and climbing conditions,and the safety and stability of construction are guaranteed,which provides some theoretical and practical experience for the application of tower crane in similar super high-rise buildings.
