Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1:

[0023] As Figure 1 、 Figure 2 shown, an adjustment platform ball joint locking structure includes:

[0024] adjustment platform 1;

[0025] Four ball hinge attitude adjustment and fixing structures; one ball hinge attitude adjustment and fixing structure includes a ball hinge 3, three oil cylinders 5 arranged around the ball hinge 3, and three groups of universal joints 4. The ball arm of the ball hinge 3 is fixedly connected to the bottom surface of the adjustment platform 1, and the ball socket of the ball hinge 3 is fixedly connected to the equipment base 2. Two universal joints 4 are in one group. The first ends of the two universal joints 4 in one group are respectively fixedly connected to both ends of an oil cylinder 5, and the second ends are respectively fixedly connected to the bottom surface of the adjustment platform 1 and the equipment base 2;

[0026] Oil circuit assembly; all the oil cylinders 5 are connected to the oil circuit assembly, and the oil circuit assembly is used to control the actions of the oil cylinders 5;

[0027] Control module; the control module is connected to the oil circuit assembly, and the control module is used to send control instructions to the oil circuit assembly.

[0028] In this embodiment, after the adjustment platform 1 of the present application completes the platform attitude adjustment through the ball hinge 3, the control module controls the oil circuit assembly, and then controls the stretching of multiple groups of oil cylinders 5 around the ball hinge 3 under the condition of unchanged torque, ensuring that multiple oil cylinders 5 reach the specified stretching position simultaneously, completing the locking of the ball hinge 3. Using the present application, the complete locking state of the ball hinge 3 can be achieved, and a single or multiple ball hinges 3 can be locked in any attitude. When multiple ball hinge supports are locked, the attitude of any ball hinge support is not changed, and the locking state is stable and will not change under external forces.

[0029] Embodiment 2:

[0030] The difference between this embodiment and Embodiment 1 is that, as Figure 1 、 Figure 2 shown, a ball hinge attitude adjustment and fixing structure further includes a jacking assembly 6. The fixed end of the jacking assembly 6 is fixedly connected to the top surface of the equipment base 2, and the lifting end of the jacking assembly 6 is fixedly connected to the ball socket of the ball hinge 3.

In addition, it also plays roles such as dissipating heat from the oil fluid, precipitating impurities, and allowing the air in the oil fluid to escape. The hydraulic pump is a power component, and its function is to provide pressurized oil. From the perspective of energy conversion, the hydraulic pump converts the mechanical energy output by a prime mover such as an engine into the pressure energy of a liquid that is convenient for transportation.

[0037] In this embodiment, the rectangular distribution can make the force on the adjustment platform 1 more uniform, enhancing the structural stability of this application.
