'an apparatus for welding platen inlet headers, de super heater lines, and recirculation system of a high pressure bioler in saw (submerged arc welding) automatic welding machine'

摘要

The invention relates to an apparatus for welding Platen inlet headers, De super heater lines, and Recirculation system of a high pressure boiler in SAW (Submerged Arc Welding) automatic welding machine, the apparatus comprising a counter weight block (4) with a fulcrum at the bottom for interlocking the block (4) with a counter weight interlock gear (5) to fix in a particular position two weight carrying beams (8) so as to conduct welding of an inter connecting box channel (6) to lift the sub-assembly to fix on the welding machine; a supporting beam (7) provided for welding between the box channel (6) and a circular pipe (9); a clamping device (2) provided to clamp the counter weight block (4);a vertical screw (10) for moving up and down to tighten or loosen the counter weight block (4) to move the assembly in horizontal directions after lifting from the fulcrum; several gripping pads (3) to avoid slipping of the counter weight block (4); wherein the circular pipe (9) is holding a work piece (11) concentrically loaded on the machine by adjusting four annular screws (12) provided on the circular pipe (9), and wherein both of the counter weight carrying beam (8) and supporting beam (7) are welded in the circular pipe (9).
