Abstract

PURPOSE: The remover which can quickly, surely pull out the tube, by rotating and sending forward the specified tube-removing jig provided with the tap at its tip inside the tube for carrying out the tapping, and then, by pulling this tube-removing jig backward.
CONSTITUTION: The center of the tap 6a of the removing jig 6 is made to coincide with the center of the hole 2a of tube plate 2; after that, the pressure oil is supplied to the inside hydraulic ram 4a for sending the lever 5a forward in the direction of arrowed mark A; as a result, the tube-removing jig 6 is rotated by the spiral screw 6c engaged with this lever 5a, and also, the tap 6a is rotated for performing the tapping on the inner surface of the tube 3. Next, the pressure oil is supplied to the outside hydraulic ram 4b so as to pull the lever 5b backward in the direction of arrowed mark B; hereby, the lever 5b strikes at the drawing plate 6d of the tube- removing jig 6 and pulls the jig 6 backward in the same direction, and hereby, removes the tube 3 from the tube plate 2 through the tap 6a. In this case, within the clamp mechanism 7, the inside clamp 7b is engaged with the jig 6 through these tooth type grooves 8,6b.
