摘　　要：现有的过轨桥式起重机锁定装置普遍采用电动液压推杆形式,该型式锁紧装置不但体积较大,而且控制系统复杂,定位精度低,为此研究设计了一种采用电机驱动四连杆传动的过轨锁紧装置.根据四连杆机构运动几何关系,在建立运动学方程的基础上,运用MATLAB软件求解非线性方程组,得到从动杆的位移、速度等参数变化情况,实现过轨锁紧过程平稳无冲击.Electrohydraulic push-rod form is widely used in present locking device of rail crane.This type of locking device is not only large in volume but also complicated with its control system,and of low positioning accuracy.Therefore,a over-rail locking device is studied and designed,in which a motor-driven four-bar linkage transmission is employed.According to the motion geometric relationships of the four-bar linkage and on the basis of establishing kinematic equation,the nonlinear equations is solved by using MATLAB software,the variation of displacement,velocity,and other parameters of the follow-up lever is obtained,and the stable,shock-free over-rail locking process is realized.
