[0023] 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.

[0024] Reference Figure 1The utility model provides an embodiment: a shell lifting structure, including a base plate 1, the base plate 1 can provide support and a stable foundation for the entire device, the four corners of the top of the base plate 1 are fixedly connected with support legs 2, so that the base plate 1 can support and fix the support legs 2, and the four support legs 2 are slidably connected to the outside of the workbench 3, so that the support legs 2 can support the workbench 3 and enable it to slide on the outside.

[0025] Reference Figure 3 The bottom of the workbench 3 is fixedly connected with a driving assembly, which is the main power source of the driving assembly. The driving assembly includes a motor 23, which is fixedly connected to the bottom of the workbench 3, so that the workbench 3 can ensure the stable support and position of the motor 23. The driving end of the motor 23 is fixedly connected with a rotating disk 4, which can drive the rotating disk 4 to rotate. The rotating disk 4 is rotatably connected to the top inner wall of the workbench 3. To ensure that the rotating disk 4 can rotate smoothly,

[0026] Reference Figure 2 Both sides of the driving assembly are rotatably connected with a rotating shaft 5, and the rotating shaft 5 is rotatably connected to both sides of the rotating disk 4, so that the rotation of the rotating disk 4 can drive the rotating shaft 5 to rotate, and the far ends of the two rotating shafts 5 are rotatably connected with a transmission block 6, so that when the rotating shaft 5 rotates, it can drive the transmission block 6 to move accordingly.

[0027] A sliding rod 7 is fixedly connected to the inside of the transmission block 6. Inside the transmission block 6, the sliding rod 7 is firmly connected to ensure that it remains integrated with the transmission block 6. Two sliding grooves 14 are provided on the inner walls on the front and rear sides of the workbench 3. The function of the sliding grooves 14 is to provide a sliding track and space for the sliding rod 7 to ensure that the sliding rod 7 can move smoothly therein. At the same time, the sliding path of the sliding rod 7 is limited by the sliding grooves 14, which can ensure that its movement range and direction meet the design requirements.

[0028] Reference Figure 1 and Figure 2 The front and rear ends of the sliding rod 7 are slidably connected with the sliding shaft 8, so that the movement of the sliding rod 7 can make the sliding shaft 8 move. A moving groove 21 is opened on the top of the workbench 3, and the sliding shaft 8 slides on the inner wall of the moving groove 21. Through the limiting of the moving groove 21, it can ensure that the sliding shaft 8 maintains a stable moving trajectory on the top of the workbench 3, so that the sliding shaft 8 can move on the inner wall of the moving groove 21.

[0029] A fixed block 9 is fixedly connected to the top of the sliding shaft 8 , and the fixed block 9 is slidably connected to the top of the workbench 3 , so that the movement of the sliding shaft 8 can drive the fixed block 9 to slide on the top of the workbench 3 .

[0030] A telescopic rod 10 is fixedly connected to the inside of the fixed block 9, so that the movement of the fixed block 9 can drive the telescopic rod 10 to move. A clamping plate 12 is fixedly connected to the inner wall of the telescopic rod 10. A spring 11 is sleeved on the outside of the telescopic rod 10. One end of the spring 11 is fixedly connected to the outside of the telescopic rod 10, and the other end of the spring 11 is fixedly connected to one side of the clamping plate 12.

[0031] By fixing the spring 11 between the telescopic rod 10 and the clamping plate 12, this design ensures that the spring 11 can participate in the support and buffering of the object during the lifting process. When the telescopic rod 10 is telescopic, the spring 11 can provide appropriate support force to the clamping plate 12 to maintain the stability and balance of the clamping plate 12.

[0032] The inner side wall of the clamping plate 12 is fixedly connected with a rubber plate 13, and then the telescopic rod 10 can drive the clamping plate 12 and the rubber plate 13 to move, so as to complete the clamping and fixing of the shells. It can be adjusted according to shells of different lengths and diameters, so it has high flexibility. Whether it is a longer or shorter, thicker or thinner shell, the position of the clamping component can be adjusted, which can increase the versatility of the device.

[0033] At the same time, the elasticity of the rubber plate 13 can absorb and mitigate external impact or vibration, play a certain shock-absorbing effect, can reduce the vibration of the shell during transportation or operation, and play a certain protective role in the personal safety of soldiers.

[0034] Reference Figure 3 A fixing plate 15 is fixedly connected to the right end of the top of the bottom plate 1, so that the bottom plate 1 can fix the fixing plate 15, and a lifting component is fixedly connected to the top of the fixing plate 15. The existence of the lowering component can adjust the height of the workbench 3 as needed to meet different operation requirements. The lifting component includes a motor 16, and the motor 16 is fixedly connected to the top of the fixing plate 15, ensuring a firm connection between the motor 16 and the fixing plate 15, so that the motor can effectively control the lifting component.

[0035] The driving end of the second motor 16 is fixedly connected to a rotating rod 17, and the outer two ends of the rotating rod 17 are rotatably connected to a rotating plate 18. The rotating rod 17 is the driving mechanism of the second motor 16. Through the rotating rod 17, the second motor 16 can transmit power and motion to the rotating plate 18. The far ends of the two rotating plates 18 are rotatably connected to support plates 24. The support plates 24 serve as extensions of the rotating plates 18. Their connection relationship ensures that power can be transmitted along the entire structure.

[0036] Two support frames 20 are fixedly connected to the left and right ends of the top of the base plate 1. The support frames 20 are rotatably connected to the outside of the rotating rod 17, so that the support frames 20 can provide support for the rotating rod 17, the rotating plate 18, and the support plate 24. The four corners of the bottom of the workbench 3 are fixedly connected with a snap-fit ​​shell 22, thereby ensuring that the workbench 3 can be firmly installed on the support leg 2 and has sufficient support and stability. The snap-fit ​​shell 22 is slidably connected to the outside of the support leg 2, and then the snap-fit ​​shell 22 slides on the surface of the support leg 2 to adjust and fix the position and stability of the workbench 3.

[0037] The two support plates 24 are rotatably connected to the push block 19 at the far end, so that the support plates 24 can rotate to adjust the height of the push block 19, and the push block 19 is fixedly connected to the bottom of the workbench 3. Therefore, through the push block 19, the motor 2 16 can drive the workbench 3 up and down to complete the height adjustment, so as to realize the required lifting or moving operation.

[0038] In summary, the motor 2 16 can effectively transmit power to the workbench 3 through a series of connections including the rotating rod 17, the rotating plate 18, the supporting plate 24 and the pushing block 19, thereby realizing the movement and operation of the entire lifting system. This design ensures the stability and reliability of power transmission, while also providing the necessary flexibility and precision for operation.

[0039] Working principle: First, place the shells to be lifted between the two groups of clamping components, and then start the motor 23. The driving end of the motor 23 can drive the rotating disk 4 to rotate. The rotation of the rotating disk 4 can drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 can make the transmission block 6 drive the sliding rod 7 to move on the inner wall of the sliding groove 14. The movement of the sliding rod 7 can drive the sliding shaft 8 to move. Then, through the limit of the sliding shaft 8 by the moving groove 21, the sliding shaft 8 can slide along the inner wall of the moving groove 21, so that the sliding shaft 8 can drive the fixed block 9 to move. The fixed block 9 can drive the telescopic rod 10 to move, and the telescopic rod 10 can drive the clamping plate 12 and the rubber plate 13 to move, so as to complete the clamping and fixing of the shells.

[0040] A spring 11 is sleeved on the outside of the telescopic rod 10. After the surface of the rubber plate 13 contacts the shell, pressure can be applied to the clamping plate 12 through the rubber plate 13, and the clamping plate 12 will apply pressure to the spring 11, so that the telescopic rod 10 can be adjusted to a suitable position, so that the clamping of the shell can be more stable. At the same time, the rubber plate 13 can also play a buffering role, thereby improving the safety of the shell lifting.

[0041] In the actual transportation process, workbenches 3 and carriers of different heights will be encountered in order to complete the system docking of the artillery shells. At this time, the motor 2 16 can be started, and then the driving end of the motor 2 16 can drive the rotating rod 17 to rotate, and the rotation of the rotating rod 17 can rotate the rotating plate 18, and the rotating plate 18 can drive the support plate 24 to rotate, and then the support plate 24, the rotation of the support plate 24 can drive the push block 19 to rise and fall, and the lifting of the push plate can drive the workbench 3 to slide on the outside of the support leg 2, so as to complete the height adjustment of the artillery shell device, thereby improving the flexibility of the device in actual use.

[0042] 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.
