[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 1 As shown, the hydraulic lifting head floor grinder provided by this utility model includes a body 1, a hydraulic pump station 2, three hydraulic cylinders 3, three mounting frames 4, and three head groups 5. Each head group 5 is connected and driven by a planetary disc to carry 12 grinding discs 11. A single-head planetary disc floor grinder can only grind with one head (equipped with 12 grinding discs). This grinder adopts a planetary grinding disc design, which can install a total of 36 grinding discs, resulting in higher efficiency. The grinding heads on the grinding disc can also revolve autonomously while rotating at high speed, achieving all-round grinding. This design makes the grinding more uniform and avoids scratches and unevenness that may occur in traditional grinding methods. Using a high-power motor and frequency converter, it is suitable for grinding various types of floor surfaces, with high power, strong drive, frequency conversion speed regulation, and stable and reliable operation.

[0023] The cylinder block of the hydraulic cylinder 3 and the hydraulic pump station 2 are fixedly arranged on the machine body 1. The hydraulic pump station 2 provides oil pressure and is connected to drive the telescopic rod of the hydraulic cylinder 3 to expand and contract. The middle part of the mounting frame 4 is vertically rotatably arranged on the machine body 1. The nose groups 5 are arranged in a triangular structure on the outer circumference of the machine body 1, distributed in a "pin" shape. Not only is the working area large, but the working lines of the three nose groups 5 overlap each other when viewed from the front and side, which can eliminate the gaps between adjacent nose groups 5, improve the grinding quality. And one end of each mounting frame 4 is hinged to the telescopic rod of a hydraulic cylinder 3, and the other end is hinged to a nose group 5. The telescopic movement of the telescopic rod of the hydraulic cylinder 3 can drive the nose group 5 to move up and down around the middle part of the mounting frame 4. When replacing the nose grinding disc 11, press the hydraulic lifting button on the door of the electric control box 9, and the hydraulic pump station 2 starts to work. At this time, the telescopic rod of the hydraulic cylinder 3 contracts, and the nose group 5 is in a state of rising at a 50° elevation angle. Then the nose grinding disc 11 can be replaced. After replacement, extend the telescopic rod of the hydraulic cylinder 3 again, and the nose group 5 descends and resets to contact the ground.

[0024] Universal wheels are arranged at the bottom of the machine body 1. The universal wheels only play a supporting role and do not need to provide a guiding function for the machine body 1, which is not shown in the figure. Front wheel groups are arranged on both the left and right sides at the front end of the machine body 1. The front wheel groups provide guiding and forward driving forces for the machine body 1. The front wheel groups include a steering drive motor 6 and a wheel frame 7. Both the steering drive motor 6 and the traveling drive motor are servo motors, which are used to precisely control the rotation position. The steering drive motor 6 is fixedly arranged on the machine body 1, and the wheel frame 7 is arranged below the steering drive motor 6. The steering drive motor 6 is connected to drive the wheel frame 7 to rotate horizontally, which is used to realize the steering of the machine body 1. The wheels can rotate 0 - 90° self-rotation, which can realize both longitudinal grinding and transverse grinding. The longitudinal grinding width can reach 2400 mm, and the transverse grinding width can reach 1600 mm. A traveling drive motor and wheels 8 are arranged on the wheel frame 7. The traveling drive motor is arranged inside the box body on the wheel frame 7. The traveling drive motor is connected to drive the wheels 8 to rotate, which is used to provide the forward driving force and can also cooperate with the steering drive motor 6 to perform steering operations simultaneously.

[0025] An electric control box 9 is also arranged on the machine body 1. A remote control receiver is arranged inside the electric control box 9, which can realize remote control operation and improve the automation level. Components such as a battery, a power inverter, a power supply, a remote control receiver, a servo driver, a frequency converter, a charger, a circuit breaker, an exhaust fan, a filter screen, a frequency converter panel, and buttons are also arranged inside the electric control box 9. A wire hanging rod 10 is also arranged on the machine body 1. The wire hanging rod 10 is horizontally rotatably arranged on the top of the machine body 1. The power cord is arranged on the wire hanging rod 10 to realize 360° horizontal rotation, preventing the wire from being wound.

[0026] Working principle:

[0027] In use, this invention enables the grinding machine to perform horizontal and vertical grinding by controlling the steering drive motor 6 and the travel drive motor. The three head groups 5 adopt a planetary grinding disc design, which can install a total of 36 grinding discs, resulting in higher efficiency. When changing the grinding disc 11, the telescopic rod of the hydraulic cylinder 3 is retracted, and the head group 5 is raised off the ground for easy replacement. After replacement, the head group 5 is lowered back to contact the ground, reducing labor intensity and improving work efficiency.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
