Description

Technical Field

[0001] This invention relates to the field of flatness equipment technology, specifically a floor grinding device. Background Technology

[0002] Currently, with economic development, people's requirements for building functions are gradually increasing, leading to a rapid emergence of buildings with extra-long and extra-wide floor plans. These are mostly used in large public buildings, industrial plants, logistics warehouses, airport parking lots and runways, etc. After construction is completed, the floor needs to be ground to ensure its quality and meet the requirements of subsequent construction, thus guaranteeing its flatness. However, in existing grinding equipment, the grinding head is generally positioned at a fixed height. Most equipment cannot adjust the grinding head height according to the unevenness of the floor surface, resulting in the grinding equipment being unable to grind burrs of varying heights, thus affecting the grinding quality of the floor. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a floor grinding device.

The grinding component includes a lifting drive unit and a grinding roller, which is connected to the vehicle-mounted base via the lifting drive unit. The leveling component includes a leveling drive unit and a grinding and polishing disc. The sensing component includes a horizontal tube, a gravity sensor, and a controller. A steel ball is rolled inside the horizontal tube, and gravity sensors are respectively installed at both ends of the horizontal tube. A spring is installed between each gravity sensor and the steel ball. The gravity sensor, the lifting drive unit, and the leveling drive unit are respectively connected to the controller. The gravity sensor transmits the collected force change signal to the controller, and the controller issues a command to drive the lifting drive unit and the leveling drive unit to operate.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] This invention utilizes a sensing component to control the lifting drive unit to move left and right, adjust the grinding roller to maintain a horizontal state, and promptly grind down any protruding areas on the floor to ensure the flatness of the floor. Then, a leveling component is used to perform secondary grinding and polishing on the floor to improve its cleanliness.

[0018] The following describes specific embodiments, such as Figures 1 to 3 The present invention is further illustrated as shown, and is intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0019] A floor grinding device comprises a vehicle-mounted base 1, grinding components, leveling components, and sensing components. The bottom of the vehicle-mounted base 1 has two rows of support frames 4, with two support frames 4 symmetrically arranged in each row. Each support frame 4 has a caster wheel 5 mounted on its bottom, and the two casters 5 of the same row of support frames 4 are connected by an axle 6. The casters 5 on the front and rear rows of support frames 4 remain flush. A push rod 2 is located at the rear end of the vehicle-mounted base 1, and a handle 3 is mounted on the push rod 2.

[0020] 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 seat 1. The piston rod of each lifting cylinder 7 is fixedly connected to a bearing seat 8. A grinding roller 14 is arranged between the two bearing seats 8. In the initial state, the grinding roller 14 is horizontal and the bottom of the grinding roller 14 is flush with the bottom of the moving wheel 5.

[0021] In this embodiment, a drive motor 10 is mounted on one of the bearing seats 8. A drive gear 9 is provided at the output end of the drive motor 10, and a driven gear 11 is mounted on the end of the grinding roller 14 corresponding to one end of the drive motor 10. The drive gear 9 meshes with the driven gear 11. The drive motor 10 drives the drive gear 9 to rotate, and the drive gear 9 drives the grinding roller 14 to rotate by meshing with the driven gear 11.

[0022] The leveling component consists of a leveling drive unit and a 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 equipped with a polishing disc 13. The bottom of the polishing disc 13 is flush with the bottom of the moving wheel 5. The rotation of the drive motor 12 drives the polishing disc 13 to rotate.

[0023] The sensing component consists of a horizontal tube 16, gravity sensors 18, and a controller. The horizontal tube 16 is horizontally mounted at the front end of the vehicle seat 1. A mounting base 15 is provided at the front end of the vehicle seat 1, and the horizontal tube 16 is placed between two mounting bases 15 and connected to the vehicle seat 1 through the mounting bases 15. Gravity sensors 18 are respectively installed at both ends of the horizontal tube 16, and steel balls 17 are rolled inside the horizontal tube 16. A spring 19 is respectively provided between each gravity sensor 18 and the steel ball 17. In this embodiment, the spring 19 is a lightweight spring. The controller in this embodiment is a PLC controller, and the lifting cylinder 7, drive motor 10, drive motor 12, and the two gravity sensors 18 are respectively connected to the controller.

[0024] In this embodiment, the entire device is moved to the ground, and then the handle 3 is slowly pushed to move the vehicle 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, it presses the light spring 19 to the left. The gravity sensor 18 on the left side transmits the collected force change signal to the controller. The controller issues an action command to control the right lifting cylinder 7 to descend and press the grinding roller 14, so that the two ends of the grinding roller 14 are kept horizontal. At the same time, the controller controls the drive motor 10. Drive motor 10 drives the grinding roller 14 to rotate through gear transmission to grind the floor until the raised floor is smooth. At this time, the roller moves on the smooth floor, 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, drive motor 10 stops rotating, and the grinding roller 14 stops grinding. Drive motor 2 starts to rotate the polishing disc 13 to perform secondary grinding and polishing on the smooth floor, thereby achieving the effect of a smooth floor.

[0025] This invention uses a gravity sensor to collect force signals and feed them back to a controller. The controller then issues action commands to control the lifting cylinder and drive motors one and two to grind and polish the raised areas of the floor, achieving the effect of grinding the floor. The height of the grinding roller can be adjusted in real time according to the changes in the floor's height, improving the flatness and cleanliness of the floor and reducing the difficulty of grinding.

[0026] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
