The operation process is cumbersome and highly dangerous, and the workload of the crew is very large. How to safely and efficiently repair the cold box motor and reduce the workload of the crew has always been a difficult problem that needs to be solved. Patent publication number CN219770477U discloses a hydraulic motor transfer rack, which uses a setting method that cooperates with the fixing component and the base plate. When the hydraulic motor needs to be transported, it can be placed on the base plate and then automatically clamped and fixed in multiple directions by the fixing component, which effectively improves the convenience of disassembly and assembly of the hydraulic motor on the base plate, and also improves the efficiency of the hydraulic motor transportation work. However, the technical solution of this patent cannot be applied to ships with a large number of deck-mounted cold boxes.
