A cryogenic plant production line

Abstract

The application discloses a cryogenic equipment production line, which comprises a carrying device, a numerical control machine tool, a plate rolling and welding device and an inner support welding assisting device, wherein the inner support welding assisting device comprises a circular ring limiting mechanism, inner support mechanisms and inner wall detection mechanisms arranged on both sides of the circular ring limiting mechanism respectively; the circular ring is placed on the circular ring limiting mechanism, then the inner support mechanisms support the inner wall of the circular ring, and the inner wall detection mechanisms are connected with the inner wall during the supporting of the inner wall of the circular ring; after the adjacent circular rings placed on the circular ring limiting mechanism are welded, the inner support mechanisms can drive the inner wall detection mechanisms to detect the inner wall roundness of the finished product circular ring during the resetting of the inner support mechanisms. The application automatically carries each semi-finished product through the carrying device, so that manual operation of a travelling crane for carrying is not needed, and workers only need to control a controller, so that the operation is simple, the labor intensity of the workers is reduced, and the workers do not need to approach the equipment and the processed products during the carrying process, so that the personal safety of the workers is ensured.
