一、上轨机构的运动学综合设计上轨机构的目的是将整体拖运的塔机自动地放到轨道上或者将轨道上的塔机自动地提起拖运。由于塔机前后两对台车很难水平放下或同时提起,所以上轨机构多数是先将塔机的一对台车放下或提起,然后再将另一对台车放下或提起。这样在每对台车上下轨道时,塔机底盘都要从第一个位置运动
1. The kinematics design of the upper track organization The purpose of the upper track mechanism is to automatically place the hauled tower crane on the track or automatically lift and haul the tower crane on the track. Since two pairs of trolleys at the front and the rear of the tower crane are difficult to be lowered horizontally or lifted at the same time, most of the upper rail vehicles first put down or lift a pair of trolleys of the tower crane, and then lower or lift the other pair of trolleys. In this way, when each pair of trolleys orbits up and down, the tower crane chassis must move from the first position
