本文首先阐述了桥式起重机理想和非理想的运行情况,产生不理想运行情况的各个因素——称之为偏差值.提出非理想运行的四种情况,认为单走轮啃道运行为最不利情况.并从运动学进一步分析了此种歪斜运行情况的特性,求出滑动率,滑动摩擦系数,滑动极点和极距,导出集中驱动和分别驱动的侧向力计算公式.文中还讨论了侧向力计算式的几个问题,指出:分别驱动桥式起重机的运行特性较集中驱动优越,产生的水平侧向力较集中驱动要小40～50%左右.桥式起重机应广泛采用分别驱动装置.文中最后对在5~t-16.5~M桥式起重机上试验测定的侧向力数据与计算值进行了比较.实测值均较计算值为大.根据对这台起重机的实测数据和我国实际使用的损坏情况,以及西德DIN15018和Hannover的实测值的综合分析,可以初步认为:从定性上看,我国现行对侧向力的取值是偏小的,须进一步研究和修订.
In this paper, firstly, the ideal and non-ideal operation of overhead traveling cranes are expounded, and all the factors which cause the unsatisfactory operation are called as deviation value. Four cases of non-ideal operation are proposed, And further analyzed the characteristics of such skewed operation from the kinematics and obtained the sliding force, sliding friction coefficient, sliding pole and pole pitch, and derived the formula of lateral force for centralized driving and separate driving.The article also discussed the side The paper points out that the driving characteristics of driving overhead traveling crane are better than those of centralized driving, and the generated horizontal lateral force is 40 ~ 50% smaller than that of centralized driving.The bridge crane should be widely used separately driving device In the last part, the lateral force data and calculated values measured on the 5 ~ t-16.5 ~ M overhead traveling crane are compared, the measured values are larger than the calculated value.According to the measured data of this crane and our country’s actual Using the damage situation and the comprehensive analysis of the measured values of DIN15018 and Hannover in West Germany, it can be preliminarily considered that qualitatively speaking, the current value of lateral force in our country is relatively small and needs to be further studied Research and revision.
