[0023] See also Figure 1-6 As shown, the technical solution provided by the utility model is: a mobile platform for ship maintenance. Although the climbing device has the function of climbing and protecting maintenance personnel, it is not convenient to lift multiple maintenance personnel and maintenance tools at the same time, and it is not convenient to use lifting or climbing methods to repair the ship according to the needs of maintenance personnel. It is also not convenient to fine-tune the maintenance position according to work needs, and the structure and function are single. The present application combines a platform structure that combines climbing and lifting, and is manually pushed to the corresponding ship maintenance location, so that the maintenance personnel and maintenance tools can be lifted to the corresponding maintenance height by the lifting mechanism 3, and the gear moving mechanism 4 is operated to place the moving plate 47 on the corresponding climbing pole 2, and the moving plate 47 is electrically fine-tuned to move to the left or right, which is convenient for repairing the corresponding ship maintenance point. Or use the climbing pole 2 to climb according to the needs of maintenance personnel.

[0024] The innovation of the present application is that the ship maintenance platform 1 comprises a fixed frame 11 and a fixed frame 12, the bottom surfaces of which are provided with universal wheels 13 with wheel brakes. The fixed frame 11 and the fixed frame 12 are connected by a connecting rod 14, so as to facilitate manual pushing of the ship maintenance platform 1 to the corresponding ship maintenance point.

[0025] In order to facilitate the lifting of maintenance personnel and maintenance tools to a certain ship maintenance height, especially to lift multiple maintenance personnel and maintenance tools together, an electric lifting structure can be used in this application: a lifting mechanism 3 is installed in the fixed frame 11, and the lifting mechanism 3 is used to lift the movable plate 47, so as to lift the maintenance tools and maintenance personnel together.

[0026] The present application is also equipped with a climbing pole 2 according to the use needs of maintenance personnel, and the climbing pole 2 is screwed into the fixing frame 12; multiple climbing poles 2 are installed longitudinally, and the front and rear ends of the climbing poles 2 are both embedded with internal screw holes 21, and the fixing frame 12 is provided with through holes corresponding to the internal screw holes 21, which are respectively fixed by bolts 23. The detachable structure of the climbing pole 2 also facilitates the placement of the moving plate 47, thereby increasing the stability of climbing.

[0027] Specifically, the lifting mechanism 3 includes a driving motor 31 with a driving shaft and a lifting threaded rod 32 coupled to the driving shaft, a gear moving mechanism 4 is screwed to the lifting threaded rod 32, and the gear moving mechanism 4 is used to fine-tune the position of the moving plate 47 to the left or right according to the ship maintenance point. A screw connection portion 41 screwed to the lifting threaded rod 32 is provided on one side of the gear moving mechanism 4, and the thread direction arranged inside the threaded portion matches the thread direction arranged outside the lifting threaded rod 32. The bottom surface and top surface of the lifting threaded rod 32 are both provided with a shaft portion 33, and the shaft portion 33 provided on the bottom surface is coupled to the driving shaft, and the shaft portion 33 provided on the top surface is connected to the top surface of the fixed frame 2 12 by installing a ball bearing. A longitudinal shaft tube 34 is embedded on the top surface of the fixed frame 2 12 to facilitate the rotation of the lifting threaded rod 32. In this embodiment, the thread direction of the external arrangement of the lifting thread rod 32 is spirally arranged from left to right. When the driving motor 31 coupling drives the lifting thread rod 32 to rotate clockwise, the thread part moves from top to bottom, and vice versa.

[0028] Further, the gear moving mechanism 4 includes a fixed block 42 and a moving frame 48 which are integrally formed with the screw connection 41. A motor 61 box is provided on the top surface of the fixed block 42. A motor 61 with an output shaft and a battery 62 are installed in the motor 61 box. A knob 63 with a switch and forward and reverse functions is provided on the top surface of the motor 61 box, which is electrically connected to the motor 61 and the battery 62 respectively. A charging hole 64 electrically connected to the battery 62 is provided on one side of the motor 61 box. In this embodiment, the models of the driving motor 31 and the motor 61 can be flexibly used and installed as needed, which is not an innovative point of this application. Power is turned on to drive the motor 31 to rotate forward and reverse. Meshing gears are installed on the bottom surface of the fixed block 42. The gears include a gear 1 43 and a gear 2 44 of the same size, and the centers of the gears are provided with a wheel axle 45. The output shaft of the motor 61 passes through the fixed block 42 and is coupled to the wheel axle 45 provided on the gear 1 43. The gear 1 43 rotates to mesh with the gear 2 44, rotates in the opposite direction, and drives the rack 49 to adjust and move back and forth. A moving plate 47 is installed in the moving frame 48. A rack 49 is provided inside the moving frame 48, which meshes with the gear 1 43 and the gear 2 44 respectively. One end of the moving frame 48 is open and provided with a limit plate 50 to prevent one end of the moving frame 48 from falling off. The bottom surface of the fixed block 42 is provided with a slide rail 51 for the sliding of the moving frame 48. The length of the moving frame 48 is less than the length of the slide rail 51, so that the moving frame 48 moves in the slide rail 51 and meshes with the gear 1 43 and the gear 2 44 for stable transmission. The slide rail 51 extends to one side of the climbing pole 2 and a roller 52 is provided at the rear end of the slide rail 51. The inner side surface of the fixed frame 2 12 is provided with a track 53 for the roller 52 to move up and down, so that the moving plate 47 can be stably lifted and lowered.

[0029] The working principle of the present application is that the ship repair tools and maintenance personnel are driven by the driving motor 31 through the lifting mechanism 3 to drive the threaded lifting rod so that the screw connection part 41 drives the moving plate 47 to move up and down. At this time, the bottom surface of the fixed block 42 in the gear moving mechanism 4 is provided with a slide rail 51, and one end of the slide rail 51 is provided with a roller 52 that moves up and down in the fixed frame 2 12, which increases the lifting stability. When the mobile ship is repaired to a corresponding height, the gear moving mechanism 4 is operated with a forward and reverse switch to control the motor 61 to make the gear 1 43 of the coupling engage with the gear 2 44 to rotate, so that the rack 49 engaged in the moving frame 48 moves the moving frame 48, and the moving plate 47 can be fine-tuned according to the ship repair point, which is convenient for the maintenance personnel and maintenance tools on the moving plate 47 to repair the corresponding ship repair point. In addition, the maintenance personnel can also climb up or down to the moving plate 47 through the auxiliary climbing pole 2 according to personal needs.
