Technical Field

[0001] The utility model relates to the technical field of ship maintenance, in particular to a vertical lifting device for ship maintenance. Background Art

[0002] After a period of operation, ships need to be regularly inspected and maintained to reduce the probability of accidents during navigation. The side of the ship is in contact with seawater or river water for a long time and is easily corroded. Even if anti-corrosion paint is applied, it still needs to be regularly inspected and maintained on shore to improve the safety of operation. Therefore, the vertical lifting method is the simplest and most effective way.

[0003] However, the existing vertical lifting equipment has a poor fixing effect on the hull, and it will shake during the lifting process, which poses a safety hazard to the workers' maintenance work. At the same time, during the maintenance process, the hull can usually only be moved by lifting equipment, which makes the hull moving process time-consuming and labor-intensive, adds unnecessary extra steps, and greatly reduces work efficiency. Utility Model Content

[0004] The technical problems to be solved by the utility model are: the fixing effect of the hull is poor, which brings potential safety hazards to workers; the hull moving process is time-consuming and labor-intensive, which greatly reduces the work efficiency.

[0006] As a further improvement of the utility model, the transmission platform assembly includes a driving motor and two horizontal plates fixedly connected to the base plate, a plurality of rotating shafts are rotatably connected between the two horizontal plates, a plurality of rotating shafts are fixedly sleeved with transmission rollers on the outer sides, a plurality of rotating shafts are fixedly connected with sprockets at both ends, a plurality of sprockets located on the same side are connected by chains, and one of the sprockets is fixedly connected to the output shaft of the driving motor.

[0007] As a further improvement of the utility model, the plurality of rotating shafts are rotatably connected to the two transverse plates via a first bearing.

[0008] As a further improvement of the present invention, the threaded rod is rotatably connected to the fixing frame via a second bearing, and the bottom end of the threaded rod is rotatably connected to the bottom plate via a third bearing.

[0009] As a further improvement of the utility model, two T-shaped sliding blocks are fixedly connected to both sides of the lifting side plate, and T-shaped sliding grooves for the T-shaped sliding blocks to slide are provided on both side walls of the fixing frame.

[0010] The beneficial effects of the utility model are as follows: the utility model can conveniently move the hull during the hull maintenance process through the transmission platform assembly, without the need for lifting equipment, thereby greatly increasing work efficiency; at the same time, the utility model can fix the hull during the hull lifting process, making it more stable during the vertical lifting process to prevent shaking, and even during the maintenance process, the hull can be kept fixed, which is convenient for the workers' subsequent work and reduces unnecessary safety hazards.
