Embodiment Construction
[0051] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:
[0052] First introduce the made support ring: such as Figures 1 to 3 , the maximum diameter of the support ring is Φ8.5m; the height of the fan-shaped block 102 is 2m, the width of the box is 0.6m, the thickness of the upper and lower cover plates of the box is 100mm, and the thickness of the arc-shaped side plate is 60mm; the diameter of the trunnion after finishing is Φ0 .9m, length 1.8m; total weight over 50 tons. The coaxiality of the trunnion is required to be ≤Φ1mm, and the flatness of the support ring is required to be ≤3mm.
[0053] The implementation steps are as follows:
[0054] (A) Preparatory stage:
[0055] 1. The upper and lower cover plates and side plates of the trunnion block and the sector block 102 are blanked and prefabricated according to the process requirements.
[0056] 2. Complete the pairing and welding of the fan-shaped ...
