Abstract:
The subject of the invention is a device for curing inner linings dragged into pipelines in the form of tubes impregnated with a UV resin. The device is equipped with a central segment of a rotating housing (1), having the form of a monolithic solid with cross-section of the shape similar to a square with two opposite sides (2 and 3) being rounded and provided with radiators (21) on their outer arched surfaces, while LEDs (17) are installed on the two other flat faces (14) of the solids; moreover, the rotating housing (1) is coupled, via a gear transmission (40), with an electric motor (39) setting said housing in rotational motion, whereas the housing has also an coaxial straight-through assembly hole (4) for electric connectors. Outer wall of said assembly hole is elongated and has side two-step annular offsets (5 and 6) and (7 and 8), with ball bearings (9) mounted on annular offsets (5 and 7) of the rotating housing (1), whereas a front annular stabilising lid (10) and a rear annular stabilising lid (10′) are mounted on the front annular offset (6) and on the rear annular offset (8) of the housing. Upper inner ends of said stabilising rings are provided with annular recesses (11) in which a sleeve-shaped shield (13) made of quarts glass is permanently mounted to protect tightly both LEDs (17) and the two radiators (21) of the rotating housing (1).
