It should be understood that the specific embodiments described below are not intended to limit the specific implementation of the technical solution of this utility model, but are merely possible implementations of the technical solution of this utility model. It should be noted that the descriptions of the positional relationships of the components herein, such as component A being located above component B, are based on the relative positions of the components in the illustrations and are not intended to limit the actual positional relationships of the components. Example 1

[0025] See Figure 1-4, Figure 1 A schematic diagram of a rapid positioning and clamping device for ship section construction according to Embodiment 1 is shown. As shown in the figure, the rapid positioning and clamping device for ship section construction according to Embodiment 1 includes a first carrier plate 3. The four corners of the bottom of the first carrier plate 3 are equipped with casters 2, which facilitates the movement of the device when not in use and makes it more convenient to position and clamp the sections.

[0026] The top four corners of the first carrier plate 3 are connected to the second carrier plate 4 via connecting rods 15. Multiple third hydraulic cylinders 12 are installed at the bottom center of the second carrier plate 4. The output end of the third hydraulic cylinder 12 is connected to the fixed base 1. The bottom of the fixed base 1 penetrates the first carrier plate 3, and an electromagnetic chuck 14 is installed at the bottom of the fixed base 1. The electromagnetic chuck 14 is mainly composed of coils, magnets, control circuits, etc. When positioning and clamping, the fixed base 1 is pushed down by the third hydraulic cylinders 12 and is attracted to the platform by the electromagnetic chuck 14, making it more stable and convenient to use. In addition, after the fixed base 1 is fixed to the platform by the third hydraulic cylinders 12, the overall height of the device can be adjusted by extending the third hydraulic cylinders 12.

[0027] A screw drive mechanism is installed at the top center of the second carrier plate 4, and a third carrier plate 5 is installed on the screw drive mechanism. The screw drive mechanism can drive the third carrier plate 5 to move laterally, which can make the hull held by the clamping plate 10 more stable and precise in positioning. Movable support devices are installed on both sides of the screw drive mechanism between the second carrier plate 4 and the third carrier plate 5. The movable support device includes a first slide groove 16 fixedly connected to the second carrier plate 4 and a guide block connected to the bottom of the third carrier plate 5. The guide block slides in the first slide groove 16 to support the third carrier plate 5 and maintain the stability and safety of the third carrier plate 5 during use.

[0028] The screw drive mechanism includes a screw box installed at the top center of the second carrier plate 4. Inside the screw box, a screw 17 connected to the output end of the motor 19 is rotatably installed. A slider 18, which is fixedly connected to the bottom of the third carrier plate 5, is threaded onto the screw 17. In use, the motor 19 is started to drive the screw 17 to rotate, thereby driving the third carrier plate 5 to move.

[0029] The third carrier plate 5 has end seats 13 symmetrically installed at the top center. A fourth carrier plate 6 is rotatably installed above the third carrier plate 5. A rotating shaft connected to the end seats 13 is installed at the bottom center of the fourth carrier plate 6. A second hydraulic cylinder 11 is fixedly installed on the continuous top of the third carrier plate 5. The output end of the second hydraulic cylinder 11 is connected to a support roller 20. The bottom of both ends of the fourth carrier plate 6 is provided with a second sliding groove 21, in which the support roller 20 can slide. When one of the second hydraulic cylinders 11 is raised, the other second hydraulic cylinder 11 is retracted, adjusting the angle of the fourth carrier plate 6, thereby facilitating the adjustment of the segmented positioning and clamping, making it more convenient to use.

[0030] The fourth carrier plate 6 has brackets 8 symmetrically installed at both ends. A first hydraulic cylinder 7 is fixedly installed on the outer side of the bracket 8. The output end of the first hydraulic cylinder 7 passes through the bracket 8 and is connected to a clamping seat 9. Multiple clamping components are installed on the inner side of the clamping seat 9. Each clamping component includes two clamping plates 10, and the ends of the two clamping plates 10 that are close to each other are rotatably connected to the middle of the clamping seat 9 via a rotating shaft. A connecting rod 23 is rotatably connected to the back of the other end of the clamping plate 10. A mounting seat 24 is rotatably installed on the other end of the connecting rod 23 via a rotating shaft. The mounting seat 24 is connected to the clamping seat 9. The clamping seat 9 is bolted together and has multiple threaded holes that mate with the mounting seat 24, facilitating the fixing of the connecting rod 23. During adjustment, the angle between the two clamping plates 10 is adjusted by changing the height of the threaded holes in the mounting seat 24. This allows for adjustment of the angle between the two clamping plates 10 according to the actual shape of the segmented ship, making it easier to fit the ship surface with different curvatures during clamping, and providing greater stability and convenience during positioning and clamping. Rubber pads 25 are adhered to the outer surface of the clamping plates 10, providing a cushioning effect and increasing friction.

[0031] Working principle:

[0032] This utility model provides a rapid positioning and clamping device for ship section construction. In use: the device is moved by the moving wheel 2. After moving to the designated position, the fixed base 1 is lowered by the third hydraulic cylinder 12. After the bottom of the fixed base 1 contacts the slipway, the electromagnetic chuck 14 at the bottom of the fixed base 1 is fixed to the slipway surface. Then, the first hydraulic cylinder 7 is activated to move the clamping seat 9. The clamping plate 10 is used to position and clamp the ship section. Before clamping, the angle between the two clamping plates 10 in the clamping assembly can be adjusted to improve the clamping effect.

[0033] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
