Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The purpose of this utility model is to provide a support mechanism with adjustable height and shape to solve the problems existing in the prior art. It has a simple structure, is easy to use, and can effectively adapt to the shape differences of different aircraft models, thus effectively ensuring equipment life and operational safety.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] This utility model provides a support mechanism with adjustable height and shape, including: a base 1, a lifting mechanism 2, a support plate 5, a first flip plate 6, a second flip plate 7, a first telescopic mechanism 8, and a second telescopic mechanism 9. The base 1 is used to install on the top surface of the chassis of a transport vehicle; the fixed end of the lifting mechanism 2 is installed on the base 1; the support plate 5 is installed on the lifting end of the lifting mechanism 2; the first flip plate 6 is hinged to one side of the support plate 5; the second flip plate 7 is hinged to the side of the support plate 5 away from the first flip plate 6; one end of the first telescopic mechanism 8 is hinged to the bottom of the support plate 5, and the other end is hinged to the first flip plate 6; one end of the second telescopic mechanism 9 is hinged to the support plate 5. The first end is hinged to the second end, and the second end is hinged to the second flip plate 7. The extension and retraction of the first telescopic mechanism 8 can drive the first flip plate 6 to flip, and the extension and retraction of the second telescopic mechanism 9 can drive the second flip plate 7 to flip. This allows the top surfaces of the first flip plate 6, the second flip plate 7, and the support plate 5 to form a support surface that matches the large irregularly shaped parts that need to be supported. By setting the first flip plate 6 and the second flip plate 7, this structure can flexibly change the shape of the support surface according to the shape of the large irregularly shaped parts, which significantly improves the adaptability to large irregularly shaped parts of different shapes, ensures stable and reliable support for large irregularly shaped parts during transportation, and enhances the versatility and practicality of the support mechanism.

[0026] In a preferred embodiment, the system further includes multiple first hinge seats. The first telescopic mechanism 8 includes multiple first hydraulic cylinders. Each first hinge seat is evenly installed on the bottom of one side of the support plate 5. One end of the first hydraulic cylinder is hinged to the first hinge seat, and the other end is hinged to the middle of the first flip plate 6. The coordinated arrangement of multiple first hydraulic cylinders and first hinge seats makes the flipping control of the first flip plate 6 more precise. The combined action of multiple cylinders can provide greater driving force, ensuring that the first flip plate 6 can be flipped smoothly and reliably to the required position, thereby better matching the shape of the irregular large parts and improving the fit and stability of the support.

[0027] In a preferred embodiment, the system further includes multiple second hinge seats. The second telescopic mechanism 9 includes multiple second hydraulic cylinders. Each second hinge seat is evenly installed on the bottom of the support plate 5 on the side away from the first flip plate 6. One end of the second hydraulic cylinder is hinged to the second hinge seat, and the other end is hinged to the middle of the second flip plate 7. Analogous to the first telescopic mechanism 8, the combination of multiple second hydraulic cylinders and second hinge seats provides a stable and precise driving force for the second flip plate 7, ensuring that the flipping action of the second flip plate 7 is smooth and accurate. This further enhances the adaptability of the support mechanism to large, irregularly shaped parts and strengthens the overall performance of the support mechanism.

[0028] In a preferred embodiment, the first telescopic mechanism 8 and the second telescopic mechanism 9 can be electric telescopic rods. Electric telescopic rods, as an optional form of the first telescopic mechanism 8 and the second telescopic mechanism 9, have the advantages of high control precision, fast response speed, and remote control capability. They can more accurately and conveniently control the flipping action of the first flipping support plate 5 and the second flipping support plate 5, making it convenient for workers to quickly adjust the shape and angle of the support surface according to the actual situation, thereby improving work efficiency.

[0029] In a preferred embodiment, the first flip plate 6, the second flip plate 7, and the support plate 5 are all arc-shaped plates. This arc-shaped plate structure allows for a closer fit with common arc-shaped irregularly shaped large components, such as aircraft nose cones, significantly increasing the contact area. The larger contact area helps to distribute the weight of the irregularly shaped large component more evenly, reducing localized pressure. This not only effectively prevents damage to the irregularly shaped large component but also improves the load-bearing capacity and stability of the support mechanism, ensuring the safety of the irregularly shaped large component during support and handling.

[0030] In a preferred embodiment, the lifting mechanism 2 includes a drive motor 21 and four screw jacks 22. The four screw jacks 22 are installed at the four corners of the top surface of the base 1, and the drive motor 21 is installed in the center of the top surface of the base 1. The output shaft of the drive motor 21 is connected to each screw jack 22 via a transmission assembly to drive the output end of the screw jack 22 to rise or fall. The output end of the screw jack 22 is fixedly connected to the bottom surface of the support plate 5. The drive motor 21, in conjunction with the screw jacks 22 at the four corners, can precisely control the lifting height of the support mechanism to adapt to different work scenarios. The four screw jacks 22 are evenly distributed at the corners, ensuring that the support mechanism is subjected to uniform force during lifting, greatly improving the stability and synchronization of lifting, and ensuring that the support mechanism can reliably support large, irregularly shaped components at different heights.

[0031] In a preferred embodiment, a horizontal rotation mechanism 3 is also included. The fixed end of the horizontal rotation mechanism 3 is installed at the output end of the screw jack 22, and the rotating end of the horizontal rotation mechanism 3 is fixedly connected to the bottom surface of the support plate 5. The setting of the horizontal rotation mechanism 3 enables the support mechanism to rotate flexibly in the horizontal direction. When facing large irregularly shaped items placed in different directions, the support surface can be quickly adjusted to a suitable direction without adjusting the position of the moving vehicle, which significantly improves the flexibility and convenience of the support operation and expands the working coverage of the support mechanism.

[0032] In a preferred embodiment, the horizontal rotation mechanism 3 is a slewing bearing. The outer ring of the slewing bearing is fixedly connected to the drive end of each screw jack 22, and the inner ring of the slewing bearing is fixedly connected to the bottom surface of the support plate 5. The slewing bearing has advantages such as compact structure, large load-bearing capacity, and smooth operation. Using a slewing bearing as the horizontal rotation mechanism 3 enables 360-degree rotation of the upper mechanism, firmly supporting the upper support plate 5 and other components, ensuring the stability and reliability of the support mechanism during horizontal rotation, and meeting the various directional adjustment requirements of complex support operations.

[0033] In a preferred embodiment, an elastic buffer mechanism 4 is further included. The bottom end of the elastic buffer mechanism 4 is fixedly connected to the inner ring of the slewing bearing, and the top end of the elastic buffer mechanism 4 is fixedly connected to the bottom surface of the support plate 5. The elastic buffer mechanism 4 plays an important role in buffering and shock absorption during the support operation. When subjected to impact forces generated by factors such as road bumps and the shift of the center of gravity of irregularly shaped large components, the elastic buffer mechanism 4 can absorb and disperse energy. The sway-capable elastic buffer mechanism 4 greatly reduces the impact of impact forces on the support mechanism and irregularly shaped large components, effectively protecting the equipment and the supported irregularly shaped large components, and extending their service life.

[0034] In a preferred embodiment, the elastic buffer mechanism 4 includes a connecting plate and multiple buffer springs. The connecting plate is fixedly connected to the inner ring of the slewing bearing. The bottom end of each buffer spring is fixedly connected to the connecting plate, and the top end is fixedly connected to the bottom surface of the support plate 5. The buffer springs are arranged in groups and evenly distributed along the circumference of the connecting plate. The elastic buffer mechanism 4, composed of multiple buffer springs, can provide stronger buffering capacity. The buffer springs evenly distributed around the circumference of the connecting plate ensure that the buffering effect is consistent across all parts of the support plate 5 when subjected to impact force, avoiding excessive local stress. This arrangement effectively enhances the ability to disperse impact force, further improving the stability and reliability of the support mechanism in dealing with unbalanced forces, and ensuring the safety and stability of the entire support operation process.

[0035] Example 2

[0036] This embodiment also provides a moving vehicle, including a height- and shape-adjustable support mechanism as described in Embodiment 1. Applying this height- and shape-adjustable support mechanism to the moving vehicle enhances its adaptability and functionality. The moving vehicle can utilize the multi-angle, height-adjustable, and cushioning protection functions of the support mechanism to handle large, irregularly shaped items of different types and shapes more easily and efficiently. This not only improves the moving vehicle's operational capabilities and applicability but also significantly enhances the safety, stability, and reliability of moving operations, providing a superior solution for related operations in fields such as aviation and large equipment handling, demonstrating broad application prospects and practical value.
