(2) The tooling is assembled with the base panels, wherein a pair of strip-shaped base panels are arranged in parallel and at intervals, a pair of parallel connecting arms arranged at intervals are connected between two ends of the strip-shaped base panels, and are fixed by bolts to form a rectangular integral frame;
(3) The installation comprises the steps of adopting a base panel to adjust a supporting frame, supporting the rectangular integral frame and abutting with a hanging beam above a ship bucket gate;
(4) Setting up a pair of reference bridge plates between upper planes of left and right brackets of a longitudinal conveyor of a ship self-unloading system, wherein the pair of reference bridge plates are respectively and correspondingly positioned below the pair of connecting arms;
(5) The quick centering correction assembly is arranged, namely the quick centering correction assembly is mounted between the reference bars of a pair of connecting arms through a detachable second hinge shaft;
(6) Adjusting, namely adjusting the supporting frame by adopting a base panel, and adjusting the left-right direction position, the height position and the front-back direction position of the rectangular integral frame by matching with the rapid measuring assembly and the rapid centering correction assembly;
(7) Spot welding and positioning, namely after the position of the rectangular integral frame is adjusted, installing reinforcing ribs between the strip-shaped base panel and the hanging beam, fixing the strip-shaped base panel on the hanging beam by spot welding, and dismantling the connecting arm after spot welding to firmly weld the strip-shaped base panel and the hanging beam.
7. The method for adjusting the adjustment support frame of the door base panel of the self-unloading system of the ship according to claim 6, wherein the adjusting method in the step (6) comprises the following steps:
S1, adjusting the height, namely starting digital display infrared distance measuring pens at two ends of a reference bridge plate, and observing the readings of the digital display infrared distance measuring pens during adjustment to ensure that the distance from the strip-shaped base panel to the upper plane of a longitudinal conveyor bracket meets a design specified value;
S2, laser centering adjustment, namely starting a central laser pen and an end laser pen on the rapid centering correction assembly, wherein the laser line of the central laser pen is aligned with a center position point of a hopper door on a bottom deck and the laser line of the end laser pen is aligned with a center line of a longitudinal conveyor bracket during adjustment, so that the left-right direction position and the front-back direction position of the rectangular integral frame are fixed;
And S3, rechecking and confirming, namely confirming the height position of the rectangular integral frame in the step S1 and the centering position of the rectangular integral frame in the step S2, and ensuring that the final position meets the requirement through fine adjustment.
