WIPO Patent Application WO/1986/002427
Kind Code:
A1
Abstract:
A device for coating the inner surface of a pipeline with the cement sand comprises a coating mechanism (1), systems (2 and 3) for feeding, correspondingly, the cement sand and a working agent, hoses (4 and 5), a pull rope (6) and a hoist (7). The shaft (8) of the drum of the hoist (7) carries, coiled up thereon, the pull rope (6) and hoses (4 and 5), the one ends of which are passing through the hollow of the shaft (8) and are connected by means of supporting units (11) of the shaft with the corresponding systems (2 and 3) for feeding the cement sand and the working agent, whereas their other ends are connected to the coating mechanism. The simultaneous winding on or winding off of the hoses (4 and 5) and the pull rope (6) allows to significantly simplify the maintenance of the device and to pass through the hoses the working agent, the cement sand and the water for washing the hose (5).
