PURPOSE:To improve operation efficiency ever so better, by connecting an extruder to a casing, where a condenser tube is housed, in time of replacing the condenser tube inside a regenerator or the like, while forcing out the tube by extrusive force of a pneumatic or hydraulic cylinder. CONSTITUTION:Gripping a handle 5, a truck 2 is shifted to some extent, while the whole lot of a device is also shifted to the vicinity of a casing 25 for a regenerator or the like. Then, an extruding pipe 10 is connected to the tip of a rod 8 of a cylinder 7 via a joint 9, connecting an extruding plate 11 to the tip. Under this condition, the tip of a rod 24 at both sides is connected to a flange 25a of the casing 25. In succession, a switch on a switch box 21 is operated, rotating a motor 12. And, a control lever 19 of a control valve 18 is operated, making the cylinder 7 operate and the rod 8 go ahead. If so, the extruding plate 11 comes into contact with the end part of a condenser tube inside the casing 25 whereby the condenser tube is extruded out of the inside of the casing 25 by extrusive force of the cylinder 7. |
