CONDUIT INNER SURFACE LUBRICANT COATER

摘要

PURPOSE: To provide a coater by which lubricant is applied to the inner circumferential surface of a conduit uniformly before a cable is pulled into the conduit. CONSTITUTION: A pulling wire 12 which is laid in a conduit is connected to the one side end of the lubricant coating vessel 6 of a conduit inner surface lubricant coater in which semi-solid lubricant 7 is stored and the vessel 6 can be moved in a longitudinal direction in the conduit by pulling the wire 12. A wire 14 is also connected to the end of a piston rod 13 which protrudes from the other side end of the lubricant coating vessel 6. A piston 8 is moved forward through the piston rod 13 by pulling the wire 14 gradually in a direction opposite to the direction of the movement to push out the lubricant 7 through a push-out hole 9.
