Gripper for remotely-operated gripping in the transport of barrels or containers

摘要

A gripper for remotely-operated gripping in the transport of barrels or containers of radioactive or toxic materials, which have on their upper side or their lid an undercut mounting ring behind which horizontally movable carrier arms or coupling bolts of the gripper engage, the coupling bolts being mounted movably in the gripper housing. The gripper has on the upper side two gripping mushrooms 7, 8 of which one 7 is arranged approximately in the geometrical centre of the gripping body 4, 6 and the other 8 is arranged eccentrically thereto. One gripping mushroom 7 is mounted rigidly on the gripping body 6, the other 8 is designed to be axially movable, penetrating the latter. The movable and eccentric gripping mushroom 8 is articulated pivotably at its lower end via a pit (recess) 16 and the rear articulation points 18 on toggle links 14. The toggle links 14 have further forward articulation points 19, with which they are articulated, likewise pivotably, on the rear ends of the coupling bolts 10. The coupling bolts 10 are mounted axially movably in bearing blocks 9 in the carrier frame 5 of the gripper. <IMAGE>
