Abrégé

Disclosed is a bellows protection connecting adjacent trolleys of a conveyor belt along an object transport line, where the conveyor belt includes trolleys movable along tracks and connected to one another by connectors allowing their reciprocal rotation at least around a vertical or horizontal axis. The device includes: a pleated covering positioned between two adjacent trolleys and connected thereto; a beam supporting the covering transversely to the direction of advancement of the transport line; and a base structure resisting vertically directed forces and supporting the beam. The base structure includes a reinforcing element binding in at least one point the beam. The reinforcing element includes: a first punctiform binder connecting it to at least one of the two trolleys; and a second punctiform binder connecting it to the at least one beam and adapted to avoid reciprocal transversal sliding between it and the at least one beam.

Abrégé

The invention relates to the sector of accessory mechanical components for conveyor belts, and in particular the invention relates to a bellows protection (1) adapted to connect adjacent trolleys (2) of a conveyor belt along an object transport line, where said conveyor belt comprises a plurality of trolleys (2) movable along tracks and connected to one another by means of connecting means (3) adapted to allow their reciprocal rotation at least around a vertical or horizontal axis. Said bellows protection bellows protection (1) comprises: - a pleated covering (4) positioned between two adjacent trolleys (2) and connected thereto; - at least one beam (5) adapted to support said covering (4) transversely to the direction of advancement of said transport line; - a base structure adapted to resist vertically directed forces and to support said at least one beam (5). Said base structure comprises at least one reinforcing element (6) positioned so as to bind in at least one point said at least one beam (5), where said at least one reinforcing element (6) comprises: - first punctiform binding means (10) adapted to connect it at least indirectly to at least one of said two trolleys (2); - second punctiform binding means (20) adapted to connect it to said at least one beam (5) and adapted to avoid reciprocal transversal sliding between it and said at least one beam (5).
