Gravel removal tube, to be attached to rotating device moved along rails of train and comprising plug of bigger diameter than tube

摘要

The tubes (5) are attached to a rotating shaft (2), to be moved along the rail of a train in order to remove gravel from the rails. One end (6) of each tube (5) is joined with a hose clip (7) to a cylindrical element (4) protruding radial from the shaft (2), the opposite end (8) is closed with a plug (9) of the same material as the tube (5) or made of rubber. The plug (9) is of a bigger diameter than the tube (5), resulting in a tight connection and an increased durability.
