The main frame is completed, other rib plates with less important functions are not in butt joint, the rib plates do not need to be matched with other parts, the requirements on form and position tolerance are lower, and the rib plates are subjected to repair welding after full welding is completed. If all parts are welded on the upper group of the invention, the structure of the invention becomes too complex, the parts interfere with each other, and the operation is inconvenient and irreparable.
The invention has the beneficial effects that: the produced guide chutes have consistent size, simplified process and good interchangeability, are not required to be assembled with other parts with good interchangeability, provide convenience for maintenance, prevent the production time of users from being delayed and improve the working efficiency. The parts with holes are drilled before welding, the position tolerance of the holes on the same flange surface is guaranteed through the positioning pins, the size of the drilled parts is small, the specification of using bench drills is reduced, and the investment of equipment is reduced for enterprises.
