古建筑平移工程中多采用滚轴作为移动装置,易产生平移偏位,且移动过程中需人工调整滚轴位置,增加了辅助工作时间。通过对滚轴支撑系统、轴承支撑系统、滚珠支撑系统进行顶推力比对试验分析发现,在相同荷载下,轴承支撑系统的顶推力与滚轴、滚珠支撑系统的顶推力相比较小,从而降低了建筑移位时的加速度,且定向性能好。对轴承支撑系统的滚动摩擦特性及受压承载力进行试验研究,结果表明,轴承支撑系统的顶推力与荷载之比F/N值较为平稳,其极限受压承载力远远高于额定载荷,安全度高、可操作性好,尤其适用于结构自重较小的平移工程。
In the ancient architecture, many rollers are used as the moving device in the translation project, which is easy to shift and deflect, and the position of the roller needs to be manually adjusted during the moving process, which increases the auxiliary work time. Through the analysis of the thrust support of the roller support system, the bearing support system and the ball support system, it is found that under the same load, the thrust force of the bearing support system is smaller than the thrust force of the roller and the ball support system, The displacement of the building when the acceleration, and good directional performance. The rolling friction characteristics and compressive bearing capacity of the bearing support system are studied. The results show that the ratio of thrust load to thrust load F / N of the bearing support system is relatively stable, and the ultimate compressive load capacity is much higher than the rated load, High safety, good maneuverability, especially for the translation of the smaller structure weight.
