ABSTRACT:
A tube lane manipulator for the high-pressure blow-down of heat exchangers with tubes spaced apart by a given tube pitch includes a guide rail extended along the tube lane having a vertical leg with holes formed therein at mutual spacings substantially matched to the tube pitch; a stepping mechanism extended along and locked to the guide rail, the stepping mechanism including two stepping mechanism members, a device for executing steps of a length substantially matched to the tube pitch, clamping feet in the form of posts, and a device for extending the posts into the holes formed in the vertical leg for fixing the stepping mechanism members in a position provided by the steps; a spraying head carrier coupled to one of the stepping mechanism members, a spraying head holder, a device for telescopically extending and guiding the spraying head holder along the spraying head carrier in a direction perpendicular to the guide rail, and a spraying head with at least one spraying nozzle disposed on the spraying head holder.
