Abstract
The proposed device comprises chain links alternately connected to upper fastening plates and to lower fastening plates. These plates comprise fastening claws of which some are arranged on the front and/or rear edges of the plates and others inside the surface of the plates. Stops are provided for blocking the chain links along the edge of the end of a conveyor belt. Another series of similar chain links are placed against the other end of the conveyor belt. The two series of chain links and plates are braced against the upper and lower sides of the respective conveyor belt ends, the claws fastening them to these ends. A connecting rod is then fitted into the chain links of the two pre-interleaved series, bringing together the conveyor belt ends in the process.
Claims13
A junction device for conveyor belts comprising:
- a first series of chain links fastened on one end of a conveyor belt;
- a second series of chain links fastened on the other end of the conveyor belt, with the first and second chain links of both first and second series being fastened to the respective ends of the conveyor belt so as to protrude with respect to such ends, the first and second series of chain links being able to be brought together in an articulated way using a connecting and articulation rod, the chain links of the first series of chain links and in the chain links of the second series of chain links being disposed alternatively and successively along said articulation rod, with the chain links of both series of chain links fastened to the respective ends of the conveyor belt having been pre-interleaved by bringing together the two conveyor belt ends;
- claws;
- in each one of the first and second series of chain links, the chain links are connected to plates, said plates having upper plates to be disposed above the conveyor belt and lower plates to be disposed under the conveyor belt with an upper branch of a first chain link being connected to an upper plate and an upper branch of a second chain link, adjacent to the first chain link, being connected to said upper plate;
- and
- a lower branch of the second chain link being connected to a lower plate, a lower branch of a third chain link, adjacent to the second chain link, being connected to said lower plate, such a disposition with the first, the second and the third chain links, being repeated along the articulation rod throughout the remaining chain links of each first and second series of chain links, said disposition allowing to receive between the upper and lower plates one end of the conveyor belt, with the upper and respective lower plates being provided with claws or hooks, the tips of which are globally oriented downwards as regards the upper plates and globally upwards as regards the lower plates, such claws being positioned on at least one edge of the plates, and/or inside the surface of the plates.
