Aerial work platform related products mainly include six categories: scissor-type aerial work platforms, vehicle-mounted aerial work platforms, articulated boom aerial work platforms, self-propelled aerial work platforms, aluminum alloy aerial work platforms, and cylinder-type aerial work platforms. The scissor-type aerial work platform is a widely used special equipment for aerial operations. Its scissor-type mechanical structure enables the lifting platform to rise, with higher stability, a wide working platform and a higher load-bearing capacity, which makes the aerial operation range larger and suitable for multiple people to work at the same time.

[0020] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 3 The utility model provides an embodiment: a scissor-type aerial work platform, including a frame 1, a scissor-type lifting mechanism 3 is provided on the upper end surface of the frame 1, and two sets of walking tracks 2 are provided on the lower end surface of the frame 1. The scissor-type lifting mechanism 3 is fixedly connected to the work platform 4 away from the upper end surface of the frame 1, an air compressor 6 is installed on one side of the upper end surface of the frame 1, and an engine 5 for providing a power source for the air compressor 6 is provided on one side of the air compressor 6. A fence 7 is provided on the upper end surface of the work platform 4, and a high-pressure air interface 12 is installed on one side of the fence 7. A connecting pipe 8 is installed at the air outlet of the air compressor 6. The connecting pipe 8 adopts a high-strength hose, and the end of the connecting pipe 8 away from the air compressor 6 is installed at the air inlet of the connecting pipe 8. Support components for stabilizing the work platform 4 are provided at the four corners of the lower end surface of the work platform 4.

[0022] Specifically, the scissor-type lifting mechanism 3 includes a hydraulic cylinder and a scissor-type lifting frame, which is a lifting mechanism commonly used in scissor-type aerial work platforms. When aerial workers use pneumatic tools, the high-pressure gas generated by the air compressor 6 can be transported to the high-pressure air interface 12 through the connecting pipe 8, thereby providing high-pressure gas for the pneumatic tools. This setting facilitates the use of pneumatic tools by workers, improves the work efficiency of aerial workers, and reduces labor intensity.

[0023] The support assembly includes a fixed cylinder 11 fixedly connected to the lower end surface of the workbench 4, the outer wall of the fixed cylinder 11 is slidably connected to the lifting cylinder 9, and the outer walls on both sides of the fixed cylinder 11 are provided with limit grooves 22. The inner side walls of the lifting cylinder 9 are fixedly connected to the sliders 23, and the sliders 23 are slidably connected to the outer walls of the lifting cylinder 9 near the limit grooves 22. The limit grooves 22 and the sliders 23 can be used to limit the moving distance of the lifting cylinder 9 to avoid excessive movement. One side outer wall of the lifting cylinder 9 is fixedly connected to the drive motor 15, and the output end of the drive motor 15 passes through one side outer wall of the lifting cylinder 9 and extends to the interior of the lifting cylinder 9 and is fixedly connected to the rotating shaft 16, and the outer wall of the rotating shaft 16 is installed with a first bevel gear 17. One side of the first bevel gear 17 is meshed with the second bevel gear 18. The lower part of the inner wall of the lifting cylinder 9 is fixedly connected to the first connecting plate 19. The second bevel gear 18 is installed inside the first connecting plate 19. The bottom end of the second bevel gear 18 is fixedly connected to the threaded rod 20 away from the first bevel gear 17. One end of the threaded rod 20 away from the second bevel gear 18 is fixedly connected to the anti-slip plate 24. The outer wall of the threaded rod 20 is threadedly connected to the second connecting plate 21. The second connecting plate 21 is fixedly connected to the lower part of the inner wall of the fixed cylinder 11. The end of the lifting cylinder 9 away from the workbench 4 is fixedly connected to the flexible pad 10. The flexible pad 10 can reduce the damage suffered by the lifting cylinder 9 when it is lifted to the ground.

[0024] Specifically, since the second connecting plate 21 is fixed inside the fixed cylinder 11, and the fixed cylinder 11 is fixed at the bottom end of the work platform 4, when the threaded rod 20 rotates, the threaded rod 20 itself can move, thereby causing the first connecting plate 21 to drive the lifting cylinder 9 to move, thereby completing the descent of the lifting cylinder 9 until the flexible pad 10 contacts the ground. This arrangement increases the stability of the work platform 4 and avoids the work platform 4 from tilting during high-altitude operations.

[0025] The four corners of the upper surface of the workbench 4 are fixedly connected to electric push rods 13, and the output ends of the electric push rods 13 are fixedly connected to the lower surface of the fence 7. The upper surface of the workbench 4 is provided with several telescopic rods 14, and the end of the telescopic rods 14 away from the workbench 4 is fixedly connected to the lower surface of the fence 7.

[0026] Specifically, this setting allows the fence 7 to be adjusted according to the height of the staff, so that the fence 7 can better protect the staff.

[0027] Working principle: When the scissor-type lifting mechanism 3 lifts the work platform 4 to a certain distance, the drive motor 15 is started, and the drive motor 15 rotates the threaded rod 20 through the first bevel gear 17 and the second bevel gear 18. Since the second connecting plate 21 is fixed inside the fixed cylinder 11, and the fixed cylinder 11 is fixed, the threaded rod 20 can descend, and then the lifting cylinder 9 is lowered through the second connecting plate 19, so the flexible pad 10 can contact the ground, increasing the stability of the work platform 4; when the high-altitude workers need to use the starting tool, they can connect the pneumatic tool to the high-pressure air interface 12, and use the engine 5 to provide power for the air compressor 6, so that the air compressor 6 can generate gas, and then the gas is transported to the high-pressure air interface 12 through the connecting pipe 8 to provide air force for the pneumatic tool.

[0028] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
