Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figure 1-8 , the present utility model provides a technical solution: a swing device for an aerial work platform, including a connecting block 1, a rotatable speed reduction mechanism 2 and a working platform 3. The speed reduction mechanism 2 includes an air chamber rod 4 and a piston rod 5. A first rotation hole 6 is provided below the connecting block 1. One end of the L-shaped air chamber rod 4 is rotatably fitted in the first rotation hole 6. A second rotation hole 7 is provided below the working platform 3. One end of the L-shaped piston rod 5 is rotatably fitted in the second rotation hole 7. A piston 8 is provided at one end of the piston rod 5. A piston ring 27 is sleeved on the piston 8. An air chamber 9 is provided in the air chamber rod 4. The piston 8 is slidably fitted with the air chamber 9 in the air chamber rod 4. An air injection port 10 is provided on the side wall of the air chamber rod 4. A connection hole 11 is provided on one side of the connecting block 1. A swing oil cylinder 12 is connected to the protruding block of the connecting block 1. Rotatable supporting blocks 13 are provided at the upper and lower ends of the swing oil cylinder 12. The working platform 3 is provided on the supporting blocks 13. Two groups of the speed reduction mechanisms 2 are arranged in a mirror image. An air injection cover 26 is provided on the air injection port 10. The working platform 3 is made of aluminum alloy material, and the aluminum alloy is lighter, reducing the lifting weight.

[0028] Among them, a sliding groove 14 is arranged above the operation platform 3 and close to one side of the connecting block 1. A toolbox 15 is arranged in the sliding groove 14. The toolbox 15 is slidably matched with the sliding groove 14 through a slider 16. A limiting hole 17 is opened in the sliding groove 14, and a limiting rod 18 is fitted in the limiting hole 17. The limiting rod 18 is connected to the operation platform 3 through a spring 19. A box cover 20 is arranged at the opening of the toolbox 15. The box cover 20 is rotatably matched with the toolbox 15 through a hinge 21. A box cover handle 22 is arranged on the box cover 20. A hook 23 is arranged above the box cover 20. An elastic rope 24 is correspondingly arranged above the inner side of the operation platform 3 and opposite to the hook 23. One end of the elastic rope 24 is provided with a hanging ring 25. The elastic rope 24 is made of rubber cowhide material and has good elasticity, and can well seal the toolbox 15 through the box cover 20.

[0029] The swing oil cylinder 12 adopts a spiral swing oil cylinder of L30-65-E-FT-180-S1-C-H, which has the advantages of large rotation angle, compact structure, high load-bearing capacity, long service life, simple maintenance and stable operation.

[0030] A specific application of this embodiment is as follows: The utility model drives the spring 19 to stretch by pulling the limiting rod 18, installs the toolbox 15 in the sliding groove 14 through the slider 16, and retracts the limiting rod 18 to engage and hold the toolbox 15 by releasing the limiting rod 18 and contracting the spring 19 to prevent the toolbox 15 from falling off. When the operation platform 3 is in a horizontal state, the air injection cover 26 is opened, and air is injected through the air injection port 10 to make the piston 8 located at the center position of the air chamber 9. After the air injection is completed, the air injection cover 26 is manually closed to ensure gas tightness. The operation platform 3 is driven to swing and turn by starting the swing oil cylinder 12. During turning, the operation platform 3 drives the piston rod 5 to rotate, so that the piston rod 5 close to the turning direction pushes the piston 8 to compress the air chamber 9 in the air chamber rod 4, and the piston rod 5 away from the turning direction stretches the piston 8 to limit the rotation speed of the operation platform 3, preventing the danger of continuous turning due to inertia when the turning stops or gets out of control. At the same time, the box cover 20 is closed through the box cover handle 22, and then the elastic rope 24 is pulled to hang the hanging ring 25 on the elastic rope 24 on the hook 23 corresponding to the box cover 20, so that the box cover 20 is tightly closed to hold too high tools and lower tools, preventing the tools from shifting or falling due to turning. This device realizes the limitation of inertia when the aerial work platform rotates through the speed reduction mechanism 2, and realizes the placement of tools through the installation of the toolbox 15 to prevent moving and falling.
