Ships are composed of various parts, including hulls, engines, deck equipment, etc. Since ships are usually very large and heavy, the use of auxiliary lifting devices is necessary during maintenance. Auxiliary lifting devices can help maintenance personnel lift and hang various parts, equipment or cargo of the ship in appropriate positions to facilitate maintenance, inspection or replacement of parts. These devices usually include cranes, hoists, winches, etc. The use of these devices can ensure the safety of maintenance personnel and carry out maintenance work effectively, while reducing the risk of damage that may be caused to the ship's structure.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 , Figure 2The utility model provides an embodiment: an auxiliary lifting device for ship maintenance, including a gantry 1, a motor 2 is fixedly connected to the upper surface of the gantry 1, a winding roller 3 is fixedly connected to the output end of the motor 2, a steel cable 4 is fixedly connected to the outer wall of the winding roller 3, a fixed shell 5 is fixedly connected to the lower surface of the steel cable 4, a connecting shell 6 is fixedly connected to the lower surface of the fixed shell 5, a motor 7 is fixedly connected to the upper surface of the connecting shell 6, the fixed shell 5 is sleeved on the outer wall of the motor 7, a worm 8 is fixedly connected to the output end of the motor 7, a worm gear 9 is rotatably connected to the inside of the connecting shell 6, two worm gears 9 are meshed with the worm 8, a connecting rod 10 is fixedly connected to the outer wall of the worm gear 9, and a clamping assembly is arranged on the outer wall of the connecting rod 10; the clamping assembly includes a clamping block 11 and a connecting rod 12, the clamping block 11 is rotatably connected to one side of the outer wall of the connecting rod 10, the outer wall of the clamping block 11 is rotatably connected to the connecting rod 12, and one side of the outer wall of the connecting rod 12 is rotatably connected to the inner wall of the connecting shell 6;

[0024] Specifically, first of all, starting motor 12 plays a key role, which drives the winding roller 3 to rotate. This step is crucial because it is the prerequisite for realizing the lifting of the steel cable 14. When the steel cable 14 is lifted and lowered to the desired position, we can place the parts on the upper surface of the clamping block 11. Next, start motor 27 so that motor 27 drives the worm 8 to mesh and rotate with the worm wheel 19. This process is to allow the connecting rod 10 to rotate smoothly. When the connecting rod 10 rotates, it will drive the clamping block 11 and the connecting rod 12 to move together. This design allows the parts to be conveniently clamped by the clamping block 11 when needed. In this process, the coordination between the various components is crucial. If any component has a problem, it may affect the operation of the entire equipment. Therefore, it is very necessary to regularly inspect and maintain the equipment to ensure the normal operation of each component. In addition, in order to improve the operating efficiency and stability of the equipment, we can also optimize and improve the equipment. For example, we can consider using more advanced motors and transmission devices to increase the operating speed and reduce energy consumption. At the same time, the design of the clamping block 11 and the connecting rod 10 can also be optimized to improve the clamping effect and safety of the components.

[0025] Reference Figure 2 , Figure 3, a left-right symmetrical rotating rod 13 is rotatably connected inside the connecting shell 6, a worm gear 14 is fixedly connected to the outer wall of the rotating rod 13, and the worm gear 14 is meshed with the worm 8; a stabilizing plate 15 is fixedly connected to the outer wall of the rotating rod 13, and a hinge block 16 is rotatably connected inside the stabilizing plate 15; a fixed plate 17 is fixedly connected to the lower surface of the hinge block 16, and a plurality of limiting rods 18 are slidably connected inside the fixed plate 17; a spring 19 is sleeved on the outer wall of the limiting rod 18, and the upper end of the spring 19 is fixedly connected to the upper surface of the fixed plate 17; a bottom plate 20 is fixedly connected to the lower surface of the bottom plate 20, and a buffer block 21 is slidably connected inside the bottom plate 20; a plurality of steel cables 22 are fixedly connected to the outer wall of the connecting shell 6, and a hook 23 is fixedly connected to the lower surface of the steel cables 22;

[0026] Specifically, the rotation of the worm 8 can drive the worm wheel 2 14 to rotate in meshing, and this mutually coordinated rotation mode makes the operation of the entire mechanical system more stable and reliable. Under the coordinated action of the worm 8 and the worm wheel 2 14, the outer wall stabilizing plate 15 of the rotating rod 13 can rotate smoothly. The stabilizing plate 15 not only has the function of this, but also drives the hinge block 16 to rise and fall synchronously. This design makes the operation of the mechanical equipment more stable and avoids failures and damage caused by asynchrony. In this process, the buffer block 21 made of silicone plays a key buffering role. When the parts are impacted, the buffer block 21 can effectively abut the parts to prevent the impact force from being too large. At this time, the bottom plate 20 plays the role of receiving pressure, so that the spring 19 can be contracted. This design effectively controls the pressure of the mechanical equipment and avoids damage to the equipment caused by excessive pressure. The bottom plate 20 is also responsible for driving the limit rod 18 to slide. This design enables the mechanical equipment to achieve precise limit control during operation to ensure the safe operation of the equipment. At the same time, the sliding design of the limit rod 18 also makes the debugging and maintenance of the equipment more convenient. Finally, the hook 23 plays a role in hanging parts. When it is necessary to repair or replace parts, the hook 23 can conveniently hang the parts, thereby making the maintenance work more convenient. This design improves the efficiency of the equipment and reduces the difficulty and cost of maintenance.

[0027] Working principle: First, the winding roller 3 is rotated by starting the motor 2, thereby achieving the effect of driving the steel cable 4 to rise and fall. At this time, the parts are placed on the upper surface of the clamping block 11. At this time, the motor 27 is started, and the worm 8 and the worm wheel 9 are meshed and rotated by the motor 27, thereby achieving the effect of driving the connecting rod 10 to rotate. The connecting rod 10 drives the clamping block 11 and the connecting rod 12 to move, thereby achieving the effect of facilitating the clamping block 11 to clamp the parts;

[0028] Secondly, by rotating the worm 8, the worm gear 2 14 can be driven to rotate in meshing, thereby achieving the effect of driving the outer wall stabilizing plate 15 of the rotating rod 13 to rotate, and the hinge block 16 is driven to rise and fall synchronously through the stabilizing plate 15, thereby driving the buffer block 21 made of silicone to abut against the parts. At this time, the pressure is received through the bottom plate 20, so that the spring 19 contracts, thereby achieving the effect of reducing the clamping pressure, and the limit rod 18 is driven to slide through the bottom plate 20, thereby achieving the effect of facilitating limited sliding, and the hook 23 can also be used to hang the parts.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
