[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1 to 4 This utility model provides a hydraulic adjustment device for a mobile frame, which includes a base frame 1. The upper end of the base frame 1 is provided with a sliding groove 6, and a first slider 4 is slidably connected to the sliding groove 6. The first slider 4 and the upper end of the base frame 1 are fixedly connected to a support seat 3. A first connecting rod 7 is rotatably connected to a plurality of support seats 3. A support frame 2 is hinged to the end of the first connecting rod 7 away from the support seat 3. A first hydraulic push rod 5 is fixedly connected to the upper end of the base frame 1. The output end of the first hydraulic push rod 5 is fixedly connected to the first slider 4. A bracket 9 is fixedly connected to the lower end of the base frame 1. A caster wheel 10 is fixedly connected to the lower end of the bracket 9. A fixing mechanism 11 is provided at the lower end of the base frame 1.

[0024] The fixing mechanism 11 includes a support leg 1101. The side wall of the bracket 9 is provided with a slide rail 12. The support leg 1101 is slidably connected to the slide rail 12. The lower end of the base frame 1 is fixedly connected to a guide rod 8. The surface of the guide rod 8 is slidably connected to a second slider 14. The second slider 14 is a metal block with a bushing, which reduces the coefficient of sliding friction and reduces wear.

[0025] The lower end of the base frame 1 is fixedly connected to a second hydraulic push rod 15. The output end of the second hydraulic push rod 15 is fixedly connected to a second slider 14. The lower end of the second slider 14 is hinged to a second connecting rod 13. The end of the second connecting rod 13 away from the second slider 14 is rotatably connected to the upper end of the support leg 1101.

[0026] The lower end of the support leg 1101 is threaded with a support rod 16, and the lower end of the support rod 16 is fixedly connected with a foot pad 17. The threaded structure allows for fine adjustment of the height of the support leg 1101, adjusting the height of each support leg 1101 to adapt to uneven ground and ensure that the base frame 1 is level. The two second connecting rods 13 are located on both sides of the lower end of the base frame 1. There are two second hydraulic push rods 15, and a synchronization valve is set between the two second hydraulic push rods 15. The synchronization valve ensures that the extension speed and stroke of the two second hydraulic push rods 15 are completely consistent, avoiding the difference in the lifting height of the support leg 1101 due to the asynchronous action of the push rods on both sides, thereby preventing the device from tilting and ensuring the stability of the fixing process.

[0027] Working principle: In use, when the height of the support frame 2 needs to be adjusted, the first hydraulic push rod 5 is activated, driving the first slider 4 to slide along the slide groove 6, which in turn drives the connected support seat 3 to move synchronously. This causes the first connecting rod 7 to rotate around the support seat 3. Since the other end of the first connecting rod 7 is hinged to the support frame 2, and the two sets of support seats 3 and the first connecting rod 7 form a parallelogram mechanism, the support frame 2 rises smoothly under the push of the first connecting rod 7 until it reaches the set height. When the device is in the moving state, the support leg 1101 of the fixing mechanism 11 is in a high position, and the caster wheel 10 is in contact with the ground. When the operator pushes the base frame 1, the caster wheel 10 rolls on the ground, realizing multi-directional movement of the device. Once the device reaches the designated working position, activate the second hydraulic push rod 15. Under the action of the synchronizing valve, the piston rods of the two push rods extend synchronously. The two second hydraulic push rods 15 simultaneously drive the second slider 14 to slide outwards along the guide rod 8. As the second slider 14 slides, it drives the support leg 1101 downwards along the slide rail 12 via the second connecting rod 13 until the foot pad 17 at the lower end of the support leg 1101 contacts the ground, lifting the base frame 1 and the caster 10 so that the caster 10 is off the ground. If the ground is uneven, observe the level of the base frame 1 and adjust the height of the corresponding support leg 1101 by rotating the support rod 16 until the base frame 1 remains level, thus securing the device and ensuring stability without shaking during operation. After the operation is completed, activate the second hydraulic push rod 15 to pull the second slider 14 inwards. This drives the support leg 1101 upwards via the second connecting rod 13, causing the caster 10 to re-contact the ground, releasing the device from its fixed position, and allowing it to move again.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
