LOADING MANIPULATOR Russian patent published in 1995 - IPC

FIELD: hoisting and transport equipment. SUBSTANCE: drive 4 and conducted 8 levers are mounted forming an angle Ψ between the longitudinal axle of lever 8 and the shortest straight line between axle 6 of the connecting rod of the arrow links and axle 5 of the connecting rod of the connection of lever 4 with the preceding arrow link. This angle is more than zero but less than that g between the mentioned shortest straight line and the longitudinal axle of the drive lever. In this case at all possible positions of the arrow links the value of the shoulder h_link of following link 7 exceeds that of shoulder h_lever of lever 4. The value l_link of the shortest distance between axle 6 and axle 11 of the connecting rod of coupling of conducted lever 8 with the following link of the arrow exceeds that of the shortest distance l_lever between axle 5 of the connecting rod of coupling of lever 8 with lever 4. At all actual angles α₁ of rotation of the arrow links the relationship h_link > h_lever is observed. At the maximum freight moment M_f.маx this relationship can be equal to . EFFECT: two times decreased area of the piston F_p of hydraulic cylinder 1. 2 dwg
