Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method for fixing the main engine traveling beam into the cabin, temporary fixing fixtures for cabin entry, and a ship. Background Technology

[0002] After the ship's engine room is assembled, the main engine needs to be hoisted into the engine room. Generally, the overhead crane beam located above the main engine is hoisted into the engine room and secured first, followed by the hoisting of the hull cover plates above the main engine. The main engine overhead crane beam is temporarily welded to the internal structure of the engine room, which involves a large amount of high-altitude welding work and requires the support of crane resources for an extended period. After the hull structure is fully assembled and welded, the overhead crane beam is then installed according to the assembly requirements.

[0003] The main engine traveling beam is installed on the hull structure above the main engine, spanning two hull sections, and cannot be pre-assembled within these sections. The engine room traveling beam is a double-rail beam, with the trolley moving back and forth via gears that mesh with a rack on the beam. Therefore, extremely high requirements are placed on the levelness and parallelism of the traveling beam, as well as the matching degree of the rack; both beams and the rack must be installed as a whole.

[0004] The current practice is to pre-install the traveling beams on the two hull sections, and then complete the installation of the traveling beams after the hull cover structure above the main engine is welded. Finally, the rack is installed. The current installation process requires a large amount of welding work, including butt welding of the traveling beams and overhead welding of the rack, after the engine room cover is closed.

[0005] In summary, the existing methods for installing the main crane beam are complex, require excessive crane resources, involve a large amount of work at height, and have low installation efficiency.

[0006] Therefore, there is an urgent need for a method for fixing the main engine traveling beam into the cabin, temporary fixing fixtures for cabin entry, and a vessel to solve the above problems. Summary of the Invention

Figures 1-3 This embodiment provides a method for fixing a main engine traveling beam into the engine room and a vessel. The vessel includes an engine room 1, a main engine, and a main engine traveling beam 100. The main engine traveling beam 100 is installed into the engine room 1 using the method provided in this embodiment.

[0032] The main steps for securing the main engine traveling beam into the cabin are as follows: Step S10: Assemble and adjust the straightness of the main crane beam 100; Step S20: Hoist the main engine traveling beam 100 into the engine room 1 of the ship and temporarily fix it below the target installation position 2; Step S30: Hoist the main engine into the engine room 1 and set up the engine room deck; Step S40: Fix the main engine traveling beam 100 and the target mounting position 2 to the same location. The target mounting position 2 is located below the engine room deck.

[0033] Specifically, step S10 includes: Step S11: Assemble the traveling beam 110 and rack 120 to form the main traveling beam 100; Step S12: Adjust the straightness of the main machine traveling beam 100.

[0034] In this embodiment, the rack 120 is assembled onto the traveling beam 110 by welding. Furthermore, in this embodiment, prestressed reverse tension can be used to correct the deformation of the main traveling beam 100.
