A bottom groove 3 is provided at the center of the bottom end of the chassis 1. A fixing frame 4 is installed on the left side of the top end of the bottom groove 3. A lead screw 5 is movably installed on the top end of the bottom groove 3. A screw sleeve 6 is provided on the outside of the lead screw 5. A drive motor 7 is installed on the right side of the bottom groove 3. The output end of the drive motor 7 is fixedly connected to the right side of the lead screw 5. The bottom ends of the fixing frame 4 and the screw sleeve 6 are movably installed... The chassis 1 is equipped with a scissor frame 8. A lifting platform 9 is movably mounted at the bottom of the scissor frame 8. A first rotating shaft 10 is movably mounted on the right side inside the lifting platform 9. A first drive wheel 11 is mounted at both ends of the first rotating shaft 10. A first driving wheel 12 is mounted on the outer side wall of the first rotating shaft 10. A first driven wheel 13 is provided on the left side of the first driving wheel 12. A first motor 14 is mounted at the front end of the first driven wheel 13. A first auxiliary wheel 15 is movably mounted on the left side of both ends of the lifting platform 9. A second rotating shaft 16 is movably mounted at the rear end inside the chassis 1. A second driving wheel 18 is mounted on the outer side wall of the second rotating shaft 16. A second driven wheel 19 is provided at the front end of the second driving wheel 18. A second motor 20 is mounted on the right side of the second driven wheel 19. A second drive wheel 17 is mounted on both sides of the second rotating shaft 16. A second auxiliary wheel 21 is movably mounted on the front end of both sides of the chassis 1.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, when in use, the second motor 20 is started, and the second driven wheel 19 cooperates with the second driven wheel 19 to drive the second rotating shaft 16 to drive the second driving wheel 17 to rotate, and the auxiliary device moves in position. When stopping, the drive motor 7 is started, and the screw sleeve 6 cooperates with the lead screw 5 to drive the scissor frame 8 to push the lifting platform 9 down. After the first driving wheel 11 contacts the ground, the chassis 1 moves up in the opposite direction, and the second driving wheel 17 and the second auxiliary wheel 21 separate from the ground. At this time, the switching of the moving wheel group is completed. The first motor 14 is started, and with the cooperation of the first driven wheel 13 and the first driving wheel 12, the first rotating shaft 10 can be driven to drive the first driving wheel 11 to rotate, and the reversing operation of the device is completed.

[0026] Both sides of the top of the chassis 1 are provided with top grooves 22, and an air pump 23 is installed inside the top groove 22. An air supply pipe 24 is installed at the top of the air pump 23. Both sides of the top of the top plate 2 are provided with bosses 25, and an air channel 26 is provided inside the bosses 25. Both sides of the air channel 26 are provided with air holes 27. Several air holes 27 are provided on both sides of the air channel 26. The air holes 27 are distributed at equal intervals. The top of the air supply pipe 24 extends into the interior of the air channel 26.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, when in use, starting the air pump 23 can accelerate the gas to be sent into the air groove 26 inside the boss 25 through the air supply pipe 24. When the gas is sprayed outward through the air holes 27 on both sides of the air groove 26, it can be sprayed onto the surface of the top plate 2. With the help of high-speed gas, it can help remove dust and debris from the surface of the top plate 2 and clean it.

[0028] The outer side wall of the chassis 1 is provided with a side groove 28. There are several side grooves 28 on the outer side wall of the chassis 1. The several side grooves 28 are symmetrically distributed. A support tube 29 is movably installed inside the side groove 28. An electric push rod 30 is installed inside the support tube 29.

[0029] Specifically, such as Figure 2 and Figure 5 As shown, when in use, starting the electric push rod 30 can help push the support tube 29 stored inside the side groove 28. When the multiple sets of support tubes 29 move downwards at an angle, after contacting the ground, the multiple sets of support tubes 29 cooperate to help support the device.

[0030] Working principle: In use, starting the second motor 20, the second driven wheel 19 engages with the second driven wheel 19 to drive the second rotating shaft 16 to rotate the second drive wheel 17, thus moving the auxiliary device. When stopping, starting the drive motor 7, the screw sleeve 6 engages with the lead screw 5 to drive the scissor frame 8 to push the lifting platform 9 downward. As the first drive wheel 11 contacts the ground, the chassis 1 moves upward in the opposite direction, and the second drive wheel 17 and the second auxiliary wheel 21 separate from the ground. At this time, the switching of the moving wheel set is completed. Starting the first motor 14, with the cooperation of the first driven wheel 13 and the first driving wheel 12, drives the first rotating shaft 10 to rotate the first drive wheel 11, completing the reversing operation of the device. At the same time, as the lifting platform 9 continues to move downward, the chassis 1 and the top plate 2 can also be raised in the opposite direction. Switching between wheel 17, second auxiliary wheel 21, first drive wheel 11, and first auxiliary wheel 15 completes the four-way movement operation of the device. At the same time, when the device is stopped and goods are being transported, the electric push rod 30 located inside the support tube 29 can be activated. The electric push rod 30 pushes the support tube 29 to move outward. As the bottom end of the support tube 29 contacts the ground, multiple sets of support tubes 29 can assist the device in reinforcement when the device is stationary. If dust or debris remains on the top surface of the top plate 2 during the transport of goods, the air pump 23 can be activated. The air pump 23 can accelerate the gas to be sent into the air groove 26 inside the boss 25 through the air supply pipe 24. When the gas is sprayed outward through the air holes 27 on both sides of the air groove 26, it can be sprayed onto the top surface of the top plate 2. With the help of high-speed gas, the dust and debris on the surface of the top plate 2 can be removed and cleaned.
