[0025] This embodiment provides a driving trolley with an adjustable support structure, which can stably adjust the horizontality of the driving trolley and the position of the support point on the ground, thereby enhancing the practicality of the driving trolley and further meeting the use needs of the driving trolley in various fields.

[0026] Combine Figures 1 to 3 As shown, the driving trolley of this embodiment includes a trolley body 10 and a support part 20. The trolley body 10 can transfer and transport the carried objects, while the support part 20 can support the trolley body 10 after transfer and transportation, and adjust the horizontality of the trolley body 10 and the position of the support point on the ground to meet the use requirements of the carried objects on the trolley body 10.

[0027] In this embodiment, the trolley body 10 includes a transmission belt 11 and a platform 12. The transmission belt 11 drives the platform 12. Several movable frames 30 are provided on the platform 12. The platform 12 of this embodiment is located on the transmission belt 11, and the transmission belt 11 drives the platform 12. A load object is installed on the platform 12, thereby achieving stable transportation of the load object.

[0028] Furthermore, a number of control boxes 40 are provided on the carrier 12 of this embodiment for controlling and exchanging information with the outside. A controller is provided in the control box 40, which controls the trolley body 10 to achieve stable transportation of the trolley body 10, and a data transmitter is provided in the control box 40 for transmitting data to achieve information interaction with the outside.

[0029] Combine Figure 2 and Figure 3 As shown, one end of the support portion 20 of this embodiment is rotatably mounted on the movable frame 30, and the support portion 20 includes a lifting drive 21, a support body 22 and a support leg 23. One end of the lifting drive 21 is mounted on the movable frame 30, and the other end is connected to the connecting frame 60 on the outer end side of the support body 22. The end of the support body 22 is installed and connected to the movable frame 30, and the other end is connected to the support leg 23. In the initial state, the support portion 20 is in an inverted state. At this time, the support portion 20 does not support the trolley body 10. When the trolley body 10 moves to a predetermined position, the lifting drive 21 is started, and the support body 22 is lowered and rotated relative to the movable frame 30. At this time, the support portion 20 is The inverted state is transformed into the upright state. When the support body 22 descends and rotates to a certain angle, the support feet 23 located at the outer ends of the support body 22 are in contact with the ground, and the support body 22 will be subjected to a reverse force, which is transmitted to the movable frame 30, thereby supporting the trolley body 10 and causing the trolley body 10 to rise. In this way, the four lifting drivers 21 are started in sequence to change the heights of the four corners of the trolley body 10, thereby realizing the adjustment of the horizontality of the trolley body 10. The ends of the lifting drivers 21 and the ends of the support body 22 of this embodiment are rotatably mounted on the movable frame 30, realizing the switching of the support part 20 between the inverted state and the upright state.

[0030] In this embodiment, there are four movable frames 30, which are respectively located at the four corners of the platform 12. The four movable frames 30 correspond to four groups of support parts 20, so the trolley body 10 can be supported from four directions, thereby improving the support stability of the trolley body 10.

[0031] like Figure 1 As shown, a swing driver 50 is provided between two adjacent movable frames 30 of this embodiment. One end of the swing driver 50 is fixed to the side of the platform 12, and the other end is connected to the movable frame 30. The lifting driver 21 and the swing driver 50 are both cylinders, hydraulic cylinders or electric cylinders. The swing driver 50 of this embodiment can adjust the swing angle of two adjacent support parts 20, thereby adjusting the position of the support point of the support foot 23 on the ground to adapt to the different overturning stability requirements of the load on the trolley. In addition, the swing driver 50 also plays a role in strengthening the fixation to avoid the support part 20 from deflecting during use, thereby ensuring the support stability of the trolley body 10.

[0032] In this embodiment, a connecting frame 60 is provided at the outer end of the support body 22, and the connecting frame 60 connects one end of the lifting driver 21 to the support body 22. When the lifting driver 21 is driven, the supporting body 22 is driven by the connecting frame 60, so that the supporting body 22 pushes the supporting foot 23 to fit on the ground, and then the support body 22 is driven by the reaction force to make the supporting body 22 rise.

[0033] In actual use, in the driving trolley of this embodiment, in the initial state, the support part 20 is in an inverted state, at which time the support part 20 does not support the trolley body 10. When the trolley body 10 carries the carried object and moves to a predetermined position, the lifting drive 21 is started, and the support body 22 is lowered and rotated relative to the movable frame 30. At this time, the support part 20 is changed from the inverted state to the upright state. When the support body 22 is lowered and rotated to a certain angle, the support foot 23 located at the outer end of the support body 22 is in contact with the ground, and the support body 22 will be subjected to a reverse force, which is transmitted to the movable frame 30, thereby supporting the trolley body 10 and causing the trolley body 10 to rise. In this way, the four lifting drives 21 are started in sequence to change the heights of the four corners of the trolley body 10, thereby realizing the adjustment of the horizontality of the trolley body 10.

[0034] In summary, the driving trolley of this embodiment has an adjustable support structure, which can stably adjust the horizontality of the driving trolley and the position of the support point on the ground, thereby enhancing the practicality of the driving trolley and further meeting the use requirements of the driving trolley in various fields. The presence of the swing drive 50 can also strengthen the connection between the two adjacent movable frames 30, so that the support part 20 can support the driving trolley more stably and improve the stability of the driving trolley.
