The present invention concerns a device for supporting and guiding supplying lines 2 intended to be used in combination with a digging tool 15, mounted on a drilling machine 1. Such a device comprises at least one support branch 4, formed by a plurality of spacers (3, 300, 301, 302), adjacent to one another in which a rope or tie-rod 16 is inserted in at least one housing 31 comprised in said spacers (3, 300, 301, 302), at least one supplying pipe 22, for such a supplying line 2 and at least one crosspiece 42, comprising at least one seat suitable for supporting the pipes 22, connected to said at least one branch 4. Each pair of adjacent spacers (3, 300, 301, 302), comprises retaining means. Such retaining means comprise at least one retaining element or hook 34, associated to a first spacer of said pair of adjacent spacers (3, 300, 301, 302) and at least one slot 35, having a shape substantially matching the shape of said retaining element or hook 34, associated to a second spacer of said pair of adjacent spacers (3, 300, 301, 302). Said at least one retaining element or hook 34 during use engages with said at least one slot 35 allowing a relative axial movement, in the longitudinal direction of the rope 16, of a predetermined amount, such as to prevent said pair of adjacent spacers (3, 300, 301, 302) from moving away from each other of a distance higher than a predetermined value as well. |
