(4) And (3) installing an anchor platform wrapping plate: positioning an anchor platform wrapping plate under the condition of guaranteeing the center of the anchor chain tube and the length of eight section positions, wherein eight section position lines on the anchor platform wrapping plate are required to coincide with corresponding involution lines on the outer plate, sampling the installation angles of the eight section positions on the anchor platform wrapping plate after the anchor platform is positioned, modifying the allowance of the anchor platform wrapping plate after the angle is determined, welding and fixing the anchor platform wrapping plate with the outer plate after the anchor platform wrapping plate is installed and positioned, and simultaneously welding and fixing the lower end face of the anchor chain tube with the anchor platform panel.
2. The method of claim 1, wherein a gap is provided between the inner and outer toggle plates, the inner toggle plates of the three toggle plates below the outer wall of the hawse pipe are provided with arc-shaped notches, and the inner toggle plates with arc-shaped notches and the corresponding outer toggle plate members form arc-shaped holes.
3. The method of claim 1, wherein the anchor cylinder is formed by welding two semi-cylinders.
4. The method of claim 1, wherein the bottom surface of the anchor lip is an arc surface.
