[0041] The utility model is described below in combination with the drawings:

[0042] As shown in Figure 2 and Figure 3 , the lifting mechanism has the functions of transportation and carrying, ground walking, ground positioning and lifting; when transportation and carrying are performed, the hand wheel 301 on the lifting platform 3 is twisted, the hand wheel 301 drives the double-rotation screw to rotate, thereby driving the support platform 302 on the lifting platform 3 to descend, until it is lowered to the lowest height as shown in Figure 3 , at this time, the base 6 is rotated, so that the bottom disc of the base 6 is flush with the bottom surface of the universal caster 5, until it contacts the ground, thereby ensuring the stability of the device, and the volume of the lifting mechanism is smallest in this state, facilitating transportation and carrying; when ground walking is performed, the base 6 is rotated, so that the bottom disc of the base 6 is separated from the ground, at this time, only the universal caster 5 contacts the ground, and ground walking in any direction can be realized; when ground positioning is needed, the lifting mechanism is moved to a determined position through the moving assembly, the base 6 is rotated, so that the bottom disc of the base 6 is rotated downward to contact the ground, until the universal caster 5 is separated from the ground, and ground positioning can be realized.

[0043] As shown in Figure 4 , the hand wheel 301 is twisted to drive the lifting platform 3 to lower the support platform 302 to a certain height, the base 6 is rotated, so that the bottom disc of the base 6 is rotated downward to contact the ground, and the universal caster 5 is separated from the ground, thereby keeping the ground positioning of the lifting mechanism; then the photoelectric load 7 is placed on the lifting interface of the lifting support 1; as shown in Figure 5 , when the lifting photoelectric load 7 walks on the ground, the base 6 is rotated, so that the bottom disc of the base 6 is rotated upward to be separated from the ground, at this time, only the universal caster 5 contacts the ground, and ground walking in any direction can be realized; when the lifting photoelectric load 7 is positioned on the ground, after reaching the loading position of the photoelectric load 7, the base 6 is rotated, so that the bottom disc of the base 6 is rotated downward to contact the ground, and the universal caster 5 is separated from the ground, thereby realizing ground positioning; when the lifting photoelectric load 7 is lifted, the hand wheel 301 is twisted forward or backward, so that the lifting platform 3 drives the support platform 302 to ascend or descend, thereby realizing the ascending and descending of the photoelectric load 7.

[0044] AsFigure 6 and Figure 7 As shown, when the optoelectronic payload 7 is installed on the drone 8, the support platform 302 on the lifting platform 3 descends to... Figure 6 The low position shown, such as Figure 4 As shown, the photoelectric load 7 is placed on the support 1, as indicated. Figure 6 As shown, the photoelectric load 7 is then positioned below the mounting interface of the drone 8. The handwheel 301 on the lifting platform 3 is rotated to raise the photoelectric load 7. The lifting device is then moved on the ground via a moving component for fine-tuning of its position. After the position is adjusted, the handwheel 301 on the lifting platform 3 is turned to raise the photoelectric load 7, ultimately enabling the photoelectric load 7 and the drone 8 to interface. The operator then performs mechanical fastening. Subsequently, the handwheel 301 on the lifting platform 3 is turned to lower the support platform 302 on the lifting platform 3 and detach it from the photoelectric load, completing the installation operation. When removing the photoelectric load 7 from the drone 8, the process is reversed. First, the support platform 302 on the lifting platform 3 is raised to align the upper support 1 with the photoelectric load 7 interface. Then, the fastening screws are removed, allowing the photoelectric load 7 to detach from the drone 8. At this point, the photoelectric load 7 sits on the interface of the upper support 1. The handwheel 301 is turned to lower the lifting platform 3 to a certain height. At this point, the photoelectric load 7 is below the height of the drone 8's belly, pushing the lifting mechanism on the ground to detach the photoelectric load 7 from the drone's belly position, completing the disassembly operation.

[0045] It should be noted that the lifting mechanism of this utility model is small in size, light in weight, has a large stroke (55-280mm), and a load capacity of no more than 20Kg, making it easy to transport and carry. It also has certain expansion capabilities; during the loading and unloading of the photoelectric load 7, the upper support 1 can be disassembled from the side, facilitating replacement of the upper support in particularly low-ceilinged spaces, and allowing for easy transfer to photoelectric loads or other equipment with different structural interfaces.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
