[0012] In conjunction with specific embodiments, Figures 1 to 3 As shown, the purpose of further illustrating the present invention is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0013] A floor grinding device is composed of a vehicle-mounted seat 1, a grinding component, a leveling component and a sensing component. Two rows of support frames 4 are arranged at the bottom of the vehicle-mounted seat 1, and two support frames 4 in each row are arranged symmetrically. A moving wheel 5 is installed at the bottom of each support frame 4, and the two moving wheels 5 of the support frames 4 in the same row are connected by an axle 6. The bottoms of the moving wheels 5 on the front and rear rows of support frames 4 are kept flush. A push rod 2 is arranged at the rear end of the vehicle-mounted seat 1, and a handle 3 is arranged on the push rod 2.

[0014] The grinding assembly consists of a lifting drive unit and a grinding roller 14. The lifting drive unit consists of two lifting cylinders 7. Each lifting cylinder 7 is fixedly connected to the bottom of the vehicle-mounted seat 1. The end of the piston rod of each lifting cylinder 7 is fixedly connected to an axle seat 8. A grinding roller 14 is arranged between the two axle seats 8. In the initial state, the grinding roller 14 is in a horizontal state, and the bottom of the grinding roller 14 is flush with the bottom of the moving wheel 5.

[0015] In this embodiment, a driving motor 10 is installed on one of the shaft seats 8, a driving gear 9 is provided at the output end of the driving motor 10, a driven gear 11 is installed at one end of the grinding roller 14 corresponding to the driving motor 10, and the driving gear 9 is meshed with the driven gear 11. The driving motor 10 drives the driving gear 9 to rotate, and the driving gear 9 drives the grinding roller 14 to rotate by meshing with the driven gear 11.

[0016] The leveling assembly consists of a leveling drive unit and a grinding and polishing disc 13. The leveling drive unit consists of two drive motors 12. Each drive motor 12 is fixedly installed in parallel at the bottom of the vehicle seat 1. The output end of each drive motor 12 is respectively installed with a grinding and polishing disc 13. The bottom of the grinding and polishing disc 13 is flush with the bottom of the moving wheel 5. The rotation of the drive motor 12 drives the grinding and polishing disc 13 to rotate.

[0017] The sensing component is composed of a horizontal tube 16, a gravity sensor 18 and a controller. The horizontal tube 16 is horizontally mounted at the front end of the vehicle seat 1. The front end of the vehicle seat 1 is provided with a mounting seat 15. The horizontal tube 16 is placed between the two mounting seats 15 and connected to the vehicle seat 1 through the mounting seat 15. Gravity sensors 18 are respectively mounted at both ends of the horizontal tube 16. Steel balls 17 are rollingly mounted inside the horizontal tube 16. Springs 19 are respectively arranged between each gravity sensor 18 and the steel balls 17. In this embodiment, the springs 19 are lightweight springs 19. The controller in this embodiment is a PLC controller. The lifting cylinder 7, the drive motor 1 10, the drive motor 2 12 and the two gravity sensors 18 are respectively connected to the controller.

[0018] When the present embodiment is used, the device is moved as a whole to the ground, and then the handle 3 is slowly pushed to move the vehicle-mounted seat 1. If the ground is uneven, the steel ball 17 in the horizontal tube 16 slides left and right according to the flatness of the ground. When the steel ball 17 moves to the left in the horizontal tube 16, the steel ball 17 squeezes the light spring 19 to the left, and the gravity sensor 18 on the left transmits the signal of the force change collected to the controller. The controller issues an action command to control the right lifting cylinder 7 to descend and squeeze the grinding roller 14, so that both ends of the grinding roller 14 remain in a horizontal state; at the same time, the controller controls the drive motor 10 , the driving motor 10 drives the grinding roller 14 to rotate through the gear transmission to grind the floor until the raised floor is polished flat. At this time, the rolling wheel moves on the flat floor, and the steel ball 17 returns to the middle position. The gravity sensor 18 on the left transmits the collected force signal to the controller. The controller issues an action command, the lifting cylinder 7 on the right stops, the driving motor 10 stops rotating, and the grinding roller 14 stops grinding; the driving motor 2 12 is started to make the grinding and polishing disc 13 rotate, and the polished floor is polished for the second time, so as to achieve the effect of flat floor.

[0019] The present invention collects force signals through a gravity sensor and feeds them back to a controller, which issues action instructions to control the lifting cylinder and drive motor one and two actions to grind and polish the raised positions of the floor, thereby achieving the effect of grinding the floor. The height of the grinding roller is adjusted in real time according to the height changes of the floor, thereby improving the flatness and cleanliness of the floor and reducing the difficulty of grinding.

[0020] The above description is only the preferred embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made by using the contents of the present invention specification and its drawings are included in the scope of rights of the present invention.
