专利汇可以提供Direct profiling and transporting apparatus专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain an economical direct profiling and transporting apparatus by using common hydraulic circuits in place of hydraulic servo mechanism.
CONSTITUTION: The apparatus of this invention comprises a multi-articulated crane 2 including a vertical post 3 and three arms 4 to 6, wherein length of the first arm 4 is equal to that of the second arm 5, the third arm 6 is extended in parallel with vertical post 3, and a cylinder is connected respectively between adjacent arms and vertical post 3. At the top of the third arm 6, there is provided a profiling detector 11 for detecting the amount of movement of suspended body 1. Further, there are provided fluidic control valves 24 to 26, 27 to 29, 41 which can supply such an amount of hydraulic fluid as required to keep required openings between adjacent arms and post 3 at a given position of crane 2, by the function of cam surfaces of cams 22 to 24 which are designed to move in response to the change of distance between hinge points P
1 and P
3 , and these control valves are driven in their biasing direction by the output of profiling detector 11.
