[0029] 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.

[0030] Reference Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a ship maintenance fixing device, including a base 1 and a transmission belt 10, the top left and right sides of the base 1 are fixedly connected with T-shaped plates 3, the inner side of the base 1 is provided with a cavity 4, the top front side of the left T-shaped plate 3 is fixedly connected with a servo motor 5, the output end of the servo motor 5 passes through the T-shaped plate 3 and is fixedly connected with a first screw rod 6, the other three corners of the inner top of the two T-shaped plates 3 are rotatably connected with a second screw rod 7, the middle and lower parts of the first screw rod 6 and the second screw rod 7 pass through the cavity 4 and are fixedly connected with a pulley 9, and the multiple pulleys 9 are connected by a transmission belt 10 for transmission, the outer middle and upper parts of the first screw rod 6 and the second screw rod 7 are threadedly connected with an L-shaped plate 8, the front and rear ends of the adjacent sides of the two L-shaped plates 8 are fixedly connected with a support belt 11, the top of the L-shaped plate 8 is provided with a clamping mechanism 2, the front and rear ends of the inner tops of the two T-shaped plates 3 are fixedly connected with a slide rod 13, and the two L-shaped plates 8 are respectively slidably connected with the outer sides of the corresponding slide rods 13;

[0031] Specifically, the servo motor 5 drives the first screw 6 to rotate, thereby driving the pulley 9 to rotate. This design method cleverly transmits power to the second screw 7, so that the pulley 9 on it rotates through the transmission belt 10. In this way, the second screw 7 can rotate smoothly, thereby driving the L-shaped plates 8 on both sides to move upward. This structural design allows the support belt 11 to move upward as well, thereby realizing the lifting and lowering of the ship. The biggest advantage of this new lifting device is that it abandons the traditional method of multiple motors driving the threaded rod to lift and lower, reducing the complexity of the device.

[0032] Reference Figure 1 , Figure 2 and Figure 4The clamping mechanism 2 includes a U-shaped frame 201 and a connecting rod 209. The two U-shaped frames 201 are respectively fixedly connected to the top of the corresponding L-shaped plate 8. The rear side of the U-shaped frame 201 is fixedly connected with a micro motor 202. The output end of the micro motor 202 passes through the U-shaped frame 201 and is fixedly connected with a bidirectional screw rod 203. The front and rear sides of the outer walls of the two bidirectional screw rods 203 are both threadedly connected with movable blocks 204. One side of the movable block 204 is rotatably connected with a first rotating shaft 205. The adjacent sides of the two U-shaped frames 201 are each provided with a clamping plate 206. The front and rear ends of the two clamping plates 206 that are away from each other are fixedly connected with a U-shaped plate 207. The inside of the U-shaped plate 207 is rotatably connected with a second rotating shaft 208. The plurality of second rotating shafts 208 are respectively connected to the corresponding first rotating shaft 205 through the connecting rod 209. The plurality of movable blocks 204 are respectively slidably connected to the inside of the corresponding U-shaped frame 201.

[0033] Specifically, the micro motor 202 can drive the bidirectional screw 203 to rotate, and the movable block 204 thereon will move toward the middle accordingly. This design enables the first rotating shaft 205 to rotate accordingly, and further drives the second rotating shaft 208 to rotate through the connecting rod 209. This linkage effect ultimately enables the clamping plates 206 on both sides to move toward the middle, and accurately clamp the two sides of the ship. The advantage of this device is that it can adapt to ships of different sizes and achieve precise fixation. In traditional support devices, the bottom of the ship needs to bear a large support force, which often causes unnecessary pressure on the bottom of the ship and affects its service life. The device mentioned in this article reduces the support force of the bottom of the ship through a clever design, thereby improving the support strength.

[0034] Reference Figure 1 and Figure 2 The inner top of the two T-shaped plates 3 is fixedly connected to a supporting rod 210 on one side away from the inner top, and a round sleeve 211 is slidably connected to the outer side of the supporting rod 210. A fixing rod 212 is fixedly connected to one side of the round sleeve 211. A groove 213 is opened in the middle of the two T-shaped plates 3. The adjacent ends of the two fixing rods 212 respectively penetrate the corresponding grooves 213 and are fixedly connected to one side of the U-shaped frame 201. The sizes of the two fixing rods 212 match the internal sizes of the corresponding grooves 213.

[0035] Specifically, the cooperation between the circular sleeve 211 and the support rod 210 can further increase the stability of the U-shaped frame 201, thereby increasing the stability of the movement of the L-shaped plate 8.

[0036] Reference Figure 1A controller 14 is fixedly connected to the front end of the right wall of the right T-shaped plate 3. The controller 14 is electrically connected to the micro motor 202 and the servo motor 5 respectively. A protective cover 15 is arranged on the outside of the controller 14. One end of the protective cover 15 is rotatably connected to one side of the corresponding T-shaped plate 3.

[0037] Specifically, the operation of the micro motor 202 and the servo motor 5 can be controlled by the controller 14 , and the protective cover 15 can protect the controller 14 from being damaged by external factors.

[0038] Reference Figure 1 , a plurality of rubber balls 12 are fixedly connected to the tops of the two support belts 11 at equal distances;

[0039] Specifically, the rubber ball 12 can prevent the bottom of the ship from directly contacting the support belt 11 and causing damage.

[0040] Working principle: When using the device, first drive the ship to be inspected to the upper side of the two support belts 11, and then the servo motor 5 can drive the first screw rod 6 to rotate, and then the pulley 9 on the first screw rod 6 will rotate accordingly, and the pulley 9 on the second screw rod 7 will also rotate through the transmission belt 10, thereby driving the second screw rod 7 to rotate, and then the L-shaped plates 8 on both sides will move upward, and the support belts 11 will also move upward, and the ship will be lifted up, and there is no need to drive the threaded rods to rotate by multiple motors to realize the lifting and lowering of the ship. The structure is relatively simple and the cost is low, which can meet the needs of users. The U-shaped frame 201 will move upwards as the L-shaped plate 8 moves upwards. At this time, the micro motor 202 can drive the bidirectional screw rod 203 to rotate, and the movable block 204 on the bidirectional screw rod 203 will move toward the middle, and the first rotating shaft 205 will rotate accordingly. The second rotating shaft 208 will also rotate via the connecting rod 209, thereby driving the clamping plates 206 on both sides to move toward the middle to clamp the two sides of the ship, so that it can fix ships of different sizes, and at the same time reduce the support force of the bottom of the ship, improve its support strength, thereby improving the practicability of the device.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
