Description

Technical Field

[0001] This utility model relates to the field of lifting outrigger technology, specifically to an automatic leveling lifting outrigger for heavy load equipment. Background Technology

[0002] In practical applications of heavy-load equipment, operations often need to be carried out on uneven ground. Traditional support legs often cannot automatically level themselves according to ground conditions, resulting in poor stability of the equipment during operation. This leads to problems such as swaying and tilting, affecting not only the normal operation and accuracy of the equipment but also potentially damaging the equipment itself and even causing safety accidents. Furthermore, the adjustment of outriggers is not flexible or efficient enough during the movement and fixing of some heavy-load equipment, failing to quickly adapt to different working scenarios. Therefore, an automatic leveling lifting outrigger is needed to solve this problem for heavy-load equipment. Utility Model Content

Detailed Implementation

[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0021] Example 1

[0022] refer to Figures 1 to 2 Example 1 describes a device including wheels 1 located at the bottom of the entire device. Wheels 1 are mounted on the bottom of a vehicle body 2 and distributed around its perimeter. An adjustment assembly is mounted on the vehicle body 2, and a top frame 9 is mounted on the adjustment assembly. Lifting and leveling assemblies 3 are fixedly mounted around the perimeter of the vehicle body 2. A second cylinder 16 is installed inside the lifting and leveling assembly 3, and a piston rod 14 is mounted at the output end of the second cylinder 16. A support leg 12 is mounted on the piston rod 14. A first cylinder 4 is mounted on the adjustment assembly, and a first air rod 5 is mounted at the output end of the first cylinder 4. A second movable rod 7 is mounted on the first air rod 5. The second movable rod 7 and the first movable rod 6 are rotatably connected via a rotating shaft 8. The first movable rod 6 and the second movable rod 7 are respectively located at the top frame 9 and the U-shaped frame on the vehicle body 2 and are rotatably connected via a shaft. A telescopic rod 19 is installed between the vehicle body 2 and the top frame 9, and the telescopic rod 19 is fixedly mounted at the bottom of the vehicle body 2 and evenly distributed around its perimeter.

[0023] In this embodiment, the telescopic rods 19 are fixedly installed at the bottom of the vehicle body 2 and evenly distributed around the perimeter. The telescopic rods 19 serve as auxiliary support and guides, ensuring that the relative movement between the top frame 9 and the vehicle body 2 is more stable.

[0024] Example 2

[0025] refer to Figures 2 to 3 Example 2 is described below. This embodiment further describes Example 1. It includes a piston sleeve 15 sleeved on the outside of the piston rod 14 of the lifting and leveling assembly 3. The outer layer of the piston sleeve 15 is protected by a protective shell 17. An installation rod 11 is fixedly installed on the piston rod 14. The installation rod 11 is sleeved with the installation part 13 on the support leg 12. A reinforcing member 10 is installed on the outer layer of the protective shell 17. A guide rod 18 is provided on the outside of the piston sleeve 15.

[0026] In this embodiment, the extension and retraction of the second cylinder 16 drives the piston rod 14 to move, thereby realizing the lifting and lowering of the support leg 12 to adapt to different ground heights and achieve the purpose of leveling.

[0027] In practical applications, when heavy-load equipment needs to be moved, the second cylinder 16 of the lifting and leveling assembly 3 retracts, raising the support leg 12, and the equipment moves using the wheels 1. After the equipment moves to the designated position, the second cylinder 16 of the lifting and leveling assembly 3 is activated, the piston rod 14 extends, and the support leg 12 descends until it contacts the ground. Depending on the flatness of the ground, each second cylinder 16 can be independently controlled to lower the support leg 12 at different positions to a suitable height, achieving initial leveling. The first cylinder 4 of the adjustment assembly is then activated, extending and retracting to move the first air rod 5. The first air rod 5 pushes the second movable rod 7. Since the second movable rod 7 and the first movable rod 6 are rotatably connected via a rotating shaft 8, and they are respectively rotatably connected to the top frame 9 and the U-shaped frame on the vehicle body 2 via shafts, the first movable rod 6 and the second movable rod 7 will rotate relative to each other, thereby adjusting the relative position between the top frame 9 and the vehicle body 2, achieving height adjustment of the top frame 9. During this process, the telescopic rod 19 plays an auxiliary support and guiding role, ensuring the stability of the adjustment process.
