MANIPULATOR ROTATING DEVICE Russian patent published in 1994 - IPC

FIELD: manipulators. SUBSTANCE: force sensor is made in the form of additional power cylinder. Its piston is linked with rod of braking device power cylinder and its body mounted for movement inside column is engageable with spring. Power cylinder rod is mounted for movement in slide and is provided with piston stroke regulator of braking device power cylinder with initial spring compression regulator mounted on its rod. Slide is provided with lug, which interacts with column. Piston heads of power cylinders of boom lifting arrangement and force sensor communicate directly with each other. Piston stroke regulator of braking device power cylinder and regulator of spring initial compression are made in the form of threaded nuts placed respectively on rods of power cylinders of braking device and force sensor. EFFECT: improved reliability of manipulator operation. 2 cl 2 dwg
