移动式塔机塔身放倒四杆机构研究

RESEARCH OF THE MOBILE TOWER CRANE TOWER DOWN FOUR-BAR LINKAGE

为解决塔式起重机转场时重心过高,通过性差的问题,将塔身及其上所附部件整体放倒固定运输,不失为一种快捷高效的方法。采用四杆机构实现塔身放倒功能,介绍了其工作原理,并对各部件进行受力分析,利用Matlab对其进行仿真和优化。算例及工程实际验证了方法的可行性和实用性。

To solve the problem of transition of the tower crane with high center of gravity,through sex difference,fixed transportation for the tower body and its attached parts being put down may be regarded as a fast and efficient method. Four-bar linkage was adopted to put down the towerbody,its working principle is introduced,then the force analysis of its components is carried,finally,its simulation and optimization is carried out through using MATLAB. The feasibility and practicability of the method are verified by numerical examples and engineering practice.
