Abstract

The invention discloses a hole plug for a paddle lifting hole and an installation method, and belongs to the technical field of ships. The hole plug comprises a first plug, a second plug and a connecting piece, the first plug is inserted into one end of the paddle lifting hole, the second plug is inserted into the other end of the paddle lifting hole, the connecting piece is located in the paddlelifting hole and is used for connecting the first plug with the second plug. According to the hole plug, a blade body can be prevented from being damaged in the process of removing the hole plug, theproblems of power fluctuation and vibration and noise are avoided, the service life of the blade is prolonged, and operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a hole plug for a blade hoisting hole and an installation method. Background technique [0002] In the technical field of ships, when installing or moving blades of larger propellers, it is usually necessary to drill hoisting holes on the blades, and the hoisting holes are used to bind ropes to hoist the blades for installation or movement. After the blade is installed, the hoisting hole needs to be filled and repaired. At present, hole plugs are used to fill and repair the lifting holes. If the filling and repairing of the lifting holes are unreasonable, the entire propeller will be unbalanced, which will have a negative impact on the propulsion system and power system of the ship. [0003] However, after the existing hole plug is installed, it is usually welded together with the blade and polished flat, and the hole plug needs to be destroyed and removed during disassembly, and ...
