[0018] Specific implementation plan
[0019] The present invention will be further described below in conjunction with the drawings and specific embodiments:
[0020] Such as Figure 1-3 As shown, the manufacturing and installation method of the azimuth rudder propeller device base of the present invention operates in the following steps:
[0021] 1. Cut the steel plate into four fan-shaped rings 4 after pretreatment, and cut out the welding groove;
[0022] 2. Splice 4 fan-shaped rings on a flat frame or platform to form a base panel 3. Anneal and flatten the panel and submit the weld and flatness (≤2mm) for inspection. Mark the front, back, left, and right marks to facilitate drilling;
[0023] 3. The upper and lower sections and inner and outer circles of the base panel are processed to remove the oxide scale and meet the requirements of the drawings (considering the stop position). The lower end surface is used as the working surface and requires finishing, and at the same time...
