The mounting end of the controller 22 is installed corresponding to the lower side of the base plate 11. The mounting end of the controller 22 is fixedly connected to the lower side of the base plate 11. The control assembly 2 also includes a control panel 23 independently located on one side of the platform assembly 1. The controller 22 is electrically connected to both the dual-axis tilt sensor 21 and the control panel 23. The independent control panel 23 allows the operator to manually adjust the tilt angle of (1) according to the weight requirements of the item.

[0021] A leveling support assembly 3 is installed at each of the four corners below the platform assembly 1. Each leveling support assembly 3 includes a mounting plate 31. The mounting end of the mounting plate 31 is installed corresponding to one side of the bottom of the platform assembly 1 and is fixedly connected to one side of the bottom of the platform assembly 1. A sleeve 32 is provided on one side of the mounting plate 31, and the mounting end of the sleeve 32 is fixedly connected to one side of the mounting plate 31. The sleeve 32 is fixedly connected to the mounting plate 31. The installation of the mounting plate 31 increases the contact area between the sleeve 32 and the platform assembly 1 when the sleeve 32 is in the assembled state, thereby improving the stability of the sleeve 32 in the assembled state. The sleeve 32 is hollow and has an internal thread on its inner wall. The cross-section of the internal thread is trapezoidal. A support rod 33 is provided inside the sleeve 2. An adjusting block 34 is fitted around the top of the support rod 33. The outer ring of the adjusting block 34 has an external thread, which is threaded to the inner ring of the sleeve 32. The internal and external threads, which are trapezoidal in cross-section, have a self-locking property when threaded. A limiting groove is provided on one side of the adjusting block 34. The top of the support rod 33 is installed corresponding to the limiting groove. The support rod 33 is rotatably connected to the adjusting block 34 through the limiting groove. A drive motor 35 is provided inside the support rod 33. An installation cavity is provided inside the support rod 33. The installation end of the drive motor 35 is installed corresponding to the bottom of the inner wall of the installation cavity. The drive motor 35 is fixedly connected to the installation cavity and electrically connected to the controller 22. The operator can access the control panel 23. The drive motor 35 can be operated via controller 22. A reducer 36 is installed at the output end of the drive motor 35, corresponding to the input end of the reducer 36. The output end of the drive motor 35 and the input end of the reducer 36 are fixedly connected. A coupling 37 is installed at the connection point between the output end of the drive motor 35 and the input end of the reducer 36. The coupling 37 is fixedly sleeved on the outer ring of the connection end between the drive motor 35 and the reducer 36. The coupling 37 makes the reducer 36 and the drive motor 35 more stable when assembled. The output end of the reducer 36 passes through support rod 33 and is installed corresponding to the inner side of the limiting groove on adjusting block 34. The output end of the reducer 36 and the adjusting block 34 are fixedly connected. Multiple heat dissipation slots are provided at the corresponding mounting cavity positions. These slots allow for ventilation and heat dissipation of components 35 and 36. When the drive motor 35 is in operation, it can drive the adjusting block 34 to rotate via the reducer 36. The rotation of the adjusting block 34, through the external thread connecting to the internal thread of the sleeve 32, allows the adjusting block 34 to move up and down along the sleeve 32. During operation, the adjusting block 34 can drive the support rod 33 to move accordingly. The outer ring of the support rod 33 is provided with multiple sets of guide strips 6, and the mounting ends of the guide strips 6 are fixedly connected to the support rod 33. A sealing plate is provided at one bottom end of the mounting plate 31, and the mounting end of the sealing plate is fixedly connected to the mounting plate 31. The outer ring of the support rod 33 and the inner ring of the sealing plate fit together, and the support rod 33 and the sealing plate are slidably connected.A limiting groove is provided on the inner ring of the sealing plate at the position corresponding to the guide strip 6. The guide strip 6 is installed correspondingly to the limiting groove. The setting of the guide strip 6 and the limiting groove can stably guide the support rod 33 along the sleeve 32, and at the same time can prevent the adjusting block 34 from driving the support rod 33 to rotate during operation. The setting of the leveling support component 3 can independently adjust the tilt angle at the four end corners of the platform component 1, so as to better and more quickly and accurately level the platform component 1 after tilting.

[0022] Each leveling support assembly 3 has a caster wheel 4 at the end furthest from the platform assembly 1. The caster wheel 4 has a braking function. A pressure sensor 5 is installed between the bottom end of the support rod 33 and the caster wheel 4. A connecting plate 7 is installed at the mounting end of the caster wheel 4. One side of the connecting plate 7 is fixedly connected to the caster wheel 4. The mounting end of the pressure sensor 5 is installed corresponding to the upper side of the connecting plate 7, and the upper side of the pressure sensor 5 is installed corresponding to the bottom end of the support rod 33. The detection end of the pressure sensor 5 is connected to the support rod 33. The bottom ends of the components abut against each other, and the pressure sensor 5 is electrically connected to the controller 22. The pressure sensor 5 is set to monitor the pressure of each leveling support component 3 in real time. A damping spring 8 is sleeved on the outer ring of the sleeve 32 on the upper side of the connecting plate 7 and the lower side of the mounting plate 31. One end of the damping spring 8 is fixedly connected to one side of the connecting plate 7, and the other end of the damping spring 8 is fixedly connected to one side of the mounting plate 31. The damping spring 8 can improve the shock absorption performance of the leveling support component 3 on the platform component 1 when it moves through the universal caster 4 after the leveling operation is adjusted.

[0023] In this embodiment, the operator first pushes the platform assembly 1 to the work point according to the work requirements. At this time, the platform assembly 1 can move stably through the universal caster 4. When the platform assembly 1 moves to the work point, it is braked and positioned by the braking function on the universal caster 4, so that the platform assembly 1 is stably placed at the work point. At this time, the dual-axis tilt sensor 21 monitors the horizontal angle of the platform assembly 1 in real time, and the pressure sensor 5 monitors the pressure value of each leveling support assembly 3 in real time.

[0024] When the platform assembly 1 tilts at an angle, the dual-axis tilt sensor 21 detects the tilt signal and sends it to the controller 22. At the same time, the pressure sensor 5 at the tilted end angle sends the pressure value to the controller 22. The controller 22 then issues a work command to the drive motor 35 at the corresponding end angle. The drive motor 35 drives the adjusting block 34 to rotate through the reducer 36. The adjustment block 34 rotates and, through the connection between the external thread and the internal thread of the sleeve 32, moves up and down along the sleeve 32. During the operation, the adjustment block 34 drives the support rod 33 to follow. The support rod 33 is limited and guided by the guide strip 6 and the limiting groove, so that the support rod 33 is longitudinally and stably adjusted along the sleeve 32 until the dual-axis tilt sensor 21 detects that the platform assembly 1 is in a horizontal state. At the same time, when the pressure values ​​of each leveling support assembly 3 are the same by multiple pressure sensors 5, the drive motor 35 stops working, thus completing the automatic leveling operation of the platform assembly 1.
