CLAMP FOR COUPLING CONVEYER BELT ENDS AND DEVICE FOR SECURING CLAMPS AT BELT ENDS Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: clamp has toothed loops for inserting a coupling pin and U-shaped housing for receiving ends of the conveyer belt between its shelves. One of the shelves is provided with inlet openings and the other with outlet openings for pressing legs of a U- shaped fixing member and chute for arranging folded ends of the legs provided on the outer surface of the shelf. Additional openings for passing one of the ends of the leg into the clamp are made in the shelf with outlet openings. The end is pressed into the conveyer belt and interposed between the shelf of the clamp and the belt when a distance between shelves decreases in hammering the fixing members. The outlet and additional openings are arranged at the ends of the chute. The device for securing clamps at the ends of conveyer belt has mandrel for pressing fixing members, guide member for mandrel, fixed stop constructed as a bearing block having curved groove for bending the leg of the fixing member. The bearing block has projections arranged along its edge with a constant step. Grooves for clamp positioning are formed between the projections. Seats for positioning of the guide member for the mandrel are provided in the projections. The surface of the curved groove is used for directing the free end of the leg of the fixing member into the additional opening. EFFECT: enhanced reliability. 5 cl, 9 dwg
