新型可离塔运行施工升降机设计
Design of new off-tower running construction hoist
【摘要】 传统建筑施工升降机只能实现货物及人员在轨垂直输送,施工效率低。以常用的SC200型施工升降机为基础,设计了一种既可自动联轨爬升,也可自动脱轨巡航的新型可离塔运行施工升降机。根据相似理论建立了1∶5原理样机模型,应用多体动力学软件对新型施工升降机在不同爬升速度下的整机运行工况进行分析,得到关键部件齿轮与齿条的啮合力曲线,并导出啮合过程的冲击载荷数据。采用有限元软件对齿轮齿条和导轨架的结构强度进行分析,并结合理论计算验证了齿轮齿条的结构安全性。在此基础上制作出新型施工升降机的原理样机,并对典型运行工况进行试验,为工程样机的设计制造提供参考。
【Abstract】 Traditional construction hoists can merely achieve vertical transportation of goods and personnel on the track, thus resulting in low efficiency in construction. In this article, based on the commonly used SC200 construction hoist, a new off-tower running construction hoist is designed, which not only automatically tracks climbing but also derails cruising. The 1∶5 principle prototype model is set up according to the similarity theory; the analysis is conducted on the operation of the construction hoist with different climbing speeds by the multi-body dynamic software. Thus, the meshing force curve of such key components as the gear and the rack is identified, and the impact load in the meshing process is obtained. The FEM software is used to explore the structural strength of the gear and the rack as well as the guide rail frame; a series of theoretical calculation are used to verify that the gear and the rack have a high standard of structural safety. On this basis, a prototype of the new construction hoist is manufactured, and typical operating conditions are tested, which provides reference for design and manufacturing of engineering prototypes.
