Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ship repair tooling, and particularly relates to a universal tooling for supporting a vane. BACKGROUND

[0002] Ships need to be overhauled after long-term use. During the ship repair process, parts such as the steering engine, grinding disc, vane, rudder post and rudder pin need to be disassembled and repaired, and then reinstalled after repair.

[0003] During the process of disassembling and assembling them in the dock, for safety, the bottom of the vane is often prepared with a threaded jack and tooling to support the vane and the rudder post. However, due to the different structures of the ship and the rudder, the different weights of the vane and the rudder post, and the different heights of the dock piers of different docks, the height of the required support tooling is also different.

[0004] In the past, during the above repair process, after the ship enters the dock, the height of the bottom of the vane and the dock bottom is measured on site, the minimum height of the threaded jack itself is subtracted, and then a seamless steel pipe and upper and lower steel pads are temporarily cut and processed, and the support tooling is then welded and manufactured on site. This temporarily manufactured support tooling has the problems of poor stability, lack of universality, time-consuming, labor-intensive, and material waste. UTILITY MODEL CONTENTS
