The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done explanation in further detail.
Two wirerope ring synchronous medical mobile platforms that this push rod drives; It is characterized in that: it is by push rod (1), and wirerope fixture (2), big wirerope ring (3), little wirerope ring (4), pulley (5), push rod wirerope fixture (6), translation plates (7), translation plates fixture (8), slideway (9) and translation grillage (10) are formed.8 pulleys (5) are installed on the translation grillage (10), lay respectively on 8 angle points of two adjacent rectangles, are wound with wirerope on it respectively, have formed big wirerope ring (3) and little wirerope ring (4), and two wirerope rings can detour around angle point pulley separately.The adjacent edge of two wireropes abuts against together, and locates on one point to link up through wirerope fixture (2), thus the active of one of them wirerope ring detour the motion all will drive another wirerope around passive detouring.Translation plates (7) is placed on the slideway (9) that is fixed on the translation grillage (10), and slideway (9) provides the supporting and the spacing effect of straight line of translation plates (7).The same limit of translation plates (7) by translation plates fixture (8) respectively with big or small two wirerope rings locate on one point be linked together.Push rod overlaps placements with one side of big wirerope ring, and its stiff end is fixed on the translation grillage (10), flexible end by through push rod wirerope fixture (6) and greatly wirerope ring (3) be linked together.
