AN APPARATUS FOR EDGE PREPARATION OF WATER WALL PANEL TUBES BY LIFTING AND POSITIONING A CHAMFERING MACHINE WITHOUT USING ELECTRIC OVERHEAD TRANSPORT (EOT) CRANE

摘要

The invention relates to an apparatus (A) for holding and positioning a chamfering machine for making edge preparation of water wall tubes. The apparatus comprises of a frame (12) with a screw rod (2) fixed at top with bush bearing and box nut (15). A cross slide through box nut (15) is connected with a hook (18) through a chain (13). The hook (18) carries a chamfering machine. A sliding base (10) consisting of wheels (9) moves on a track (17) to move the whole apparatus with the chamfering machine in x-y direction. A rotating base (7) fixed on the top of a sliding base (10) is connected with the frame (12) through guiding tube (11). The tube (11) rests on a rotating cylinder (8) with an in built locking mechanism. The apparatus can be rotated by the rotating cylinder (8) and can be locked at any angle for carrying out edge preparation of inclined panel assembly tubes. A chain (3) and sprocket (4) on with a rotating handle (5) is disposed for linear movement of chamfering machine. A hydraulic rock provides vertical movement of the apparatus and the machine. A box nut guiding rod (1), the cross slide and an interconnector provides a precise movement of the chamfering machine.
