[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: Refer to Figures 1-4 As shown: A safety fixing structure for shipbuilding includes a guide frame 10. A calibration mechanism is provided on the top of the guide frame 10. The calibration mechanism includes a support clamp 3, a reinforcing plate 9, and a buffer plate 13. An extension plate 21 is fixedly connected to the bottom of the support clamp 3. An electric push rod 5 is embedded inside the extension plate 21. A limit plate 6 is fixedly connected to one end of the electric push rod 5. One side of the reinforcing plate 9 is fixedly connected to the guide frame 10. A hydraulic cylinder 11 is embedded inside the reinforcing plate 9. A positioning plate 8 is fixedly connected to one end of the hydraulic cylinder 11. A buffer rod 12 is fixedly connected to one side of the positioning plate 8. One end of the buffer rod 12 is fixedly connected to the buffer plate 13. The bottom of the buffer plate 13 is slidably connected to the guide frame 10. A guide roller is rotatably connected to one side of the guide frame 10. A hydraulic push rod 7 is fixedly connected to the bottom of the support clamp 3. A guide plate 2 is fixedly connected to the bottom of the hydraulic push rod 7. A cross plate 1 is engaged on one side of the guide plate 2. A conveying assembly 4 is bolted to the bottom of the guide plate 2. One end of the conveying assembly 4 is fixedly connected to the guide frame 10.

[0020] The conveying assembly 4 provides power for the movement of the hull, and the guide plate 2 and the cross plate 1 guide the movement of the hull, improving the stability of the hull during movement. When the hydraulic cylinder 11 extends, it pushes the positioning plate 8 to move towards the hull. When the positioning plate 8 contacts the component, the buffer rod 12 absorbs the impact force during positioning through its own elastic deformation. At the same time, the buffer plate 13 slides along the guide frame 10 to further disperse the pressure and provide buffer protection for one side of the hull. The electric push rod 5 extends and pushes the limiting plate 6 to move towards the component until the limiting plate 6 is in contact with the hull. When combined with the buffer plate 13, it can position both ends of the hull and reduce the positional deviation of the hull.

[0021] Example 2: Figures 1-4 As shown, a lead screw slide 15 is fixedly connected to one side of the guide frame 10. An adjusting frame 14 is slidably connected to the top of the lead screw slide 15. The adjusting frame 14 and the lead screw of the lead screw slide 15 are connected by threads. A motor 20 is fixedly connected to the top of the adjusting frame 14. A gear 16 is fixedly connected to one end of the output shaft of the motor 20. A rack 17 meshes on both sides of the gear 16. A clamping frame 18 is fixedly connected to one end of each rack 17. The clamping frame 18 is L-shaped. The bottom of the clamping frame 18 is slidably connected to the adjusting frame 14. A clamping plate 19 is bolted to one side of the clamping frame 18. The bottom of the clamping plate 19 is slidably connected to the guide frame 10.

[0022] When the lead screw slide 15 is started, the lead screw rotates, driving the adjusting frame 14 to move along the guide rail of the lead screw slide 15, adjusting the overall position of the adjusting frame 14 and the subsequent clamping assembly. When the motor 20 is powered on and rotates, it drives the gear 16 to rotate clockwise or counterclockwise. Since the gear 16 meshes with the racks 17 on both sides, it drives the two racks 17 to move synchronously. The reverse movement of the racks 17 drives the two clamping frames 18 to slide towards or in opposite directions along the guide rail of the adjusting frame 14. When they slide towards each other, the two L-shaped clamping frames 18 and the clamping plate 19 come into contact with each other from both sides of the hull to achieve clamping.

[0023] The operation and working principle of this device are as follows: First, a drive structure is installed on one side of the conveying assembly 4, which can drive the conveying roller of the conveying assembly 4 to rotate. The boat to be fixed is placed on top of the conveying assembly 4. The rotation of the conveying roller drives the boat to move above the conveying assembly 4. When the boat moves, the guide plate 2 and the cross plate 1 guide the boat, so that the boat moves above the guide frame 10 until one end of the boat overlaps with the buffer plate 13. The conveying assembly 4 stops operating, the hydraulic push rod 7 drives the support clamp 3 and the extension plate 21 to move down, and the electric push rod 5 drives the limit switch. Plate 6 moves so that one side of the limiting plate 6 is in contact with the stern of the boat. At this time, both ends of the boat are in contact with the buffer plate 13 and the limiting plate 6 respectively, completing the boat calibration. The motor 20 is used with a gearbox and is driven by an external controller. The motor 20 drives the gear 16 to rotate. The gear 16 drives the racks 17 on both sides to move. The racks 17 and the clamping frame 18 move along the adjusting frame 14, so that the clamping plates 19 on both sides move closer to the boat. The two symmetrical clamping plates 19 are used to clamp the boat and fix it.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
