[0003] When a street lamp is being produced and processed, the surface of the street lamp column needs to be ground, and a grinding device is required at this time.

[0004] After retrieval, the patent publication number CN212265353U discloses a grinding device for processing street lamp columns using solar energy, including a box body and a dust collection tank. Panels are arranged on both the left and right sides of the box body, and legs are arranged below the panels. The right side of the motor is connected to a rotating shaft, and the right side of the rotating shaft is connected to the inner wall of the grinding barrel. Ball bearings are arranged around the outer surface of the inner wall of the grinding barrel, and a grinding barrel is arranged on the outer surface of the ball bearings. A grinding layer is arranged on the inner surface of the inner wall of the grinding barrel. A leakage groove is opened below the inner surface of the inner wall of the grinding barrel. The dust collection tank is arranged below the box body, and a dust suction machine is arranged inside the dust collection tank. This grinding device for processing street lamp columns using solar energy is provided with ball bearings, which can facilitate the rotation of the inner wall of the grinding barrel, save electric power resources, prevent excessive loss of the motor, and increase the service life of the motor.

Because the outer wall of the guide rod 10 has a clearance connection with the hole wall of the through hole 13, it can play a role in limiting and guiding the movement of the moving mechanism 2.

[0031] When the staff polishes the surface of the street lamp pole, the two ends of the street lamp pole are placed on the tops of two second mounting seats 17, and the street lamp pole penetrates through the rotating cylinder 9. After the staff starts the first electric push rod 22, and the first electric push rod 22 drives the fixed clamping plate 24 to move in the Y-axis direction and makes the fixed clamping plate 24 fixedly clamp the street lamp pole, the staff starts the second electric push rod 28. The telescopic movement of the second electric push rod 28 will indirectly drive the grinding roller 33 to move in the Y-axis direction and make the grinding roller 33 contact with the surface of the street lamp pole. The staff starts the first reduction motor 7 and the second reduction motor 204. Starting the first reduction motor 7 will indirectly drive the rotating cylinder 9 to rotate. The rotation of the rotating cylinder 9 will indirectly drive the grinding roller 33 to rotate. The rotation of the grinding roller 33 will polish the surface of the street lamp pole. The second reduction motor 204 will indirectly drive the first rotating shaft 210 to rotate forward or backward. Since the external thread on the outer wall of the first rotating shaft 210 and the threaded hole 209 on the moving plate 207 are in threaded engagement connection, the forward or reverse rotation of the first rotating shaft 210 will make the moving plate 207 move in a straight line in the X-axis direction. The moving plate 207 moving in a straight line in the X-axis direction can indirectly drive the rotating cylinder 9 to move reciprocally in the X-axis direction. When the rotating cylinder 9 moves reciprocally in the X-axis direction, it can reciprocally polish the surface of the street lamp pole. Therefore, the utility model is convenient for polishing the surfaces of street lamp poles with different outer diameters, enhancing the versatility, and can also polish the four sides of the outer wall of the street lamp pole simultaneously, improving the polishing efficiency of the street lamp pole. When the grinding roller 33 contacts the surface of the street lamp pole, it will cause a certain interaction force. The pressure detection sensor 31 continuously detects the force exerted by the grinding roller 33 on the outer wall of the street lamp pole. When the magnitude of the force detected by the pressure detection sensor 31 reaches within the preset pressure data value range, the PLC controller 15 controls the second electric push rod 28 to close, thereby avoiding the situation that the force exerted by the grinding roller 33 on the outer wall of the street lamp pole is too large, resulting in the surface of the street lamp pole being polished too deeply, and avoiding the situation that the force exerted by the grinding roller 33 on the outer wall of the street lamp pole is too small, resulting in the surface of the street lamp pole being polished too shallowly, thus improving the polishing effect of the surface of the street lamp pole.
