Tooling for fixing hooks connecting the ends of belt conveyors

摘要

Tooling intended for fixing hooks connecting the ends of belt conveyors including a fixed lower part forming an anvil linked to a movable upper part by positioning and centering fingers, a main punch, and a complementary punch. The main punch includes a head provided with enlarged parts and can slide in a vertical channel. The complementary punch can slide in a vertical channel. A vertical guiding groove staple is arranged on the side of the complementary punch. A pneumatic hammer provided with a head hammers the main punch which drives the staple in and drives, or hammers, the complementary punch which simultaneously hammers the upper of the hook.

1. Tooling for fixing hooks connecting the ends of a belt conveyor of the type including an upper plate (5′) and a lower plate (5″′) connected by lugs (5″), positioned on the ends of a conveyor belt (BT), with the lugs (5″) being able to be connected after having being imbricated, by a linking and swivel rod, like a hinge, said tooling including a movable upper part (2) and a fixed lower part (3) positioned and centered with respect to each other by positioning and centering means, with the upper part (2) being able to vertically slide towards or away from the lower part (3), the lower part (3) including an anvil (3′) and wedging means for the lower plate (5′″) of a hook (5) positioned between the upper part (2) and the lower part (3), the upper part (2) including a vertical channel (2′) for receiving a main punch (1) substantially centered above the anvil (3′) and being able to be hammered, using a manual hammer or a device of the pneumatic, electromechanical or hydraulic hammer type mounted in the upper part, to drive in staples (7) engaged with capping into holes provided in the upper plate (5′) of a connection hook (5) positioned astride on a rim of one end of the conveyor belt (BT) positioned between the upper part (2) and the lower part (3), then in the material of the end of the conveyor belt, with prongs thereof being further folded either under the lower plate (5′″) of the hook (5) and meeting recesses having an appropriate shape provided in the anvil (3′) of the lower part (3) or under a bridge or bridges provided in the lower plate (5′″) of the hook (5) with the upper part of the lower plate (5′″) of the hook playing the part of an anvil, with a lower face of the lower plate (5′″) of the hook resting on the anvil of the lower plate which, in the later case, is smooth,
the upper part (2) including a second vertical channel (2′41 ) in which a complementary punch (4) is mounted so as to be able to slide in this channel (2′″) parallel to the main punch (1) while being juxtaposed next to the main punch (1) , and being able to be hammered, using the manual hammer or the device of the pneumatic, electromechanical or hydraulic hammer type mounted in the upper part (2) of the tooling, wherein the complementary punch (4) is positioned so that a lower end thereof is located above a part of the upper plate (5′) of the hook (5) located between the lugs (5″) and a branch of the staple (7) which is the closest to the lugs (5″), wherein a vertical dimension of the complementary punch (4) is substantially equal to a vertical dimension of the main punch (1), when the main punch (1) has driven the staple and applied the part of the upper plate (5′) of the hook (5) located under the staple (7) against an upper face of the end of the conveyor belt (BT), apexes of both the main and complementary punches are at the same level and are hit together by the manual hammer or the pneumatic, electromechanical or hydraulic hammer.
