[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1 to 3 As shown, this embodiment includes a support platform 1, a scissor arm assembly 2, a first hydraulic cylinder arm 3, a second hydraulic cylinder arm 4, and a base frame 5. A limiting platform 11 is installed on one side of the support platform 1 by bolts. Its height is adapted to the bottom thickness of the air compressor, which can laterally limit the air compressor placed on the support platform 1, effectively preventing the air compressor from sliding or deviating during the lifting or moving of the device, thus improving the safety of operation. At the same time, guide wheels 12 are symmetrically installed at the four corners of the lower end of the support platform 1, which facilitates the flexible movement of the entire device or the adjustment of the working position without the need for additional handling equipment.

[0016] like Figures 1 to 3 As shown, the scissor arm assembly 2 is the core lifting structure of the device, including an outer support arm 21 and an inner support arm 22. The inner support arm 22 and the outer support arm 21 are arranged in a cross-hinged structure, and the inner support arm 22 is adapted to be installed inside the outer support arm 21, which effectively reduces the overall space occupied in this embodiment. A connecting pin 211 is integrally formed in the middle of the outer support arm 21. Correspondingly, a connecting hole 221 adapted to the connecting pin 211 is opened in the middle of the inner support arm 22. The inner support arm 22 is sleeved on the connecting pin 211 through the connecting hole 221, realizing the rotatable connection between the outer support arm 21 and the inner support arm 22.

[0017] like Figure 1 As shown, the upper and lower ends of the outer support arm 21 and the inner support arm 22 are respectively provided with an upper connecting block 6 and a lower connecting block 7. The upper connecting block 6 is fixedly connected to the lower end face of the bearing platform 1 by bolts, and the lower connecting block 7 is also fixedly connected to the upper end face of the base frame 5 by bolts. The connection points of the upper connecting block 6 and the lower connecting block 7 with the outer support arm 21 and the inner support arm 22 are all equipped with reamed bolts 8. The reamed bolts 8 have both connecting and guiding functions, improving the rigidity and rotational flexibility of the connection parts.

[0018] To elaborate further, such as Figure 1 As shown, a hinged roller 9 is also embedded inside the upper end of the outer support arm 21. The hinged hole bolt 8 passes through the hinged roller 9 and is connected to the upper connecting block 6. The sliding friction is converted into rolling friction through the hinged roller 9, which reduces the wear between the hinged hole bolt 8 and the outer support arm 21 and extends the service life of the device.

[0019] like Figures 1 to 3 As shown, an upper connecting seat 222 and a lower connecting seat 223 are integrally formed on both sides of the middle portion of the inner support arm 22. An upper connecting ear plate 224 extending upward along the inner support arm 22 is formed in the upper connecting seat 222, and a lower connecting ear plate 225 extending downward along the inner support arm 22 is formed in the lower connecting seat 223. Both the upper connecting ear plate 224 and the lower connecting ear plate 22 are provided with pin holes. Correspondingly, a first connecting arm 212 and a second connecting arm 213 are integrally formed at the upper and lower ends of the outer support arm 21, respectively. A first ear plate 214 is formed at the end of the first connecting arm 212, and a second connecting arm 213 is formed at the end of the second connecting arm 212. The end of the first hydraulic cylinder arm 3 is provided with a second ear plate 215. The first ear plate 214 and the second ear plate 215 are also provided with pin holes. The lower end of the first hydraulic cylinder arm 3 is hinged to the lower connecting ear plate 225 by a pin, and the upper end is hinged to the first ear plate 214 by a pin. The upper end of the second hydraulic cylinder arm 4 is hinged to the upper connecting ear plate 224 by a pin, and the lower end is hinged to the second ear plate 215 by a pin, forming a dual hydraulic cylinder arm cooperative drive structure. The driving force can be distributed and transmitted to the scissor arm assembly 2, avoiding force concentration during lifting and ensuring that the bearing platform 1 is lifted and lowered smoothly, and preventing the air compressor from being damaged by vibration.

[0020] To elaborate further, such as Figure 1 As shown, the base frame 5 is formed by welding square tubes, and the overall structure is stable, providing a stable support foundation for the device.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
