In the installation of ship equipment, the installation of shafting is the most important thing, also has higher requirement to the installation of shafting lobe seal. Because the ship shafting is generally not horizontal, an included angle is formed between the shaft and the bulkhead wall. The installation difficulty of the shafting bulkhead seal is increased.
In the shafting bulkhead seal installation, the perpendicularity between the shafting bulkhead seal and the shafting is kept after the shafting bulkhead seal is installed. In the conventional installation, a shaft system compartment seal welding seat plate is firstly welded on a cabin wall by using a hoist and an adjusting support, as shown in figure 2. In order to ensure the perpendicularity between the bulkhead seal welded seat plate and the shaft system, the position of the welded seat plate needs to be repeatedly measured through a dial indicator, a gauge stand and a pagoda iron, as shown in fig. 3. The position of the welding seat plate is adjusted by the adjusting support according to the measuring result, the adjusting difficulty is high, and the installation requirement of a large-sized bulkhead sealing seat plate is difficult to meet. And adjusting the welding seat plate to meet the installation requirement, then welding, and finally installing the bulkhead on the welding seat plate in a sealing manner. The method is difficult and time-consuming when the position of the shafting compartment seal welding base plate is adjusted, and the perpendicularity of the mounted compartment seal cannot be effectively guaranteed. Along with the larger ship is built, the shaft system is longer and thicker, the compartment sealing device is enlarged, the positioning difficulty of the welding seat plate is higher, the installation quality of equipment is difficult to ensure by an old compartment sealing device installation method, and a new installation method needs to be developed.
