Due to the limitations of cost and welding technology, the protrusions at the welds will be uneven. If the welds are not polished, the protrusions and burrs at the welds will cause uneven spraying during the later painting, affecting the later painting and rust prevention process. The existing technology mostly uses manual polishing, but due to the long length of the street light poles, the time and workload of manually polishing a single street light pole are extremely large, which can easily affect the polishing accuracy and efficiency.

[0016] The beneficial effects of the utility model are as follows:
[0017] 1. The utility model provides a grinding guide device. When the equipment is in use, the base and the side plate are placed on the ground, and the welded street lamp pole is inserted from the grinding guide device. The clamping device clamps and fixes one end of the polished street lamp pole. The side plate increases the contact area between the base and the ground to prevent the bottom of the base from tilting up when the lamp pole gradually moves toward the side plate. The collecting plate collects the polished debris to prevent the debris from scattering. In the process of inserting the street lamp pole, the street lamp is placed obliquely on the top of the guide strip. As the equipment starts to grind and polish, in order to make the polishing more uniform, the lamp pole is pushed to rotate along the outer wall of the roller. When the street lamp pole is placed on the guide strip, under the pressure of the street lamp pole, the right end of the guide strip moves downward and contacts the ground, the spring sheet bends, and the bracket drives the roller to roll along the upper surface of the base. As the lamp pole is continuously pushed in, the overall center of gravity gradually approaches the side plate, and the guide strip gradually becomes horizontal. The obliquely placed guide strip can The process of loading and unloading the pole is convenient and has a certain labor-saving effect. During this process, the motor drives the pulley group outside it to rotate, and the rotating pulley group drives the top grinding disc and the bottom grinding disc to rotate through the belt pulley. During the rotation of the two grinding discs, the two grinding discs contact and rub against the outer surface of the street light pole to grind and polish the protruding parts of the weld. The motor drives the belt and belt pulley in the pulley group to rotate, and the belt pulleys at both ends of the fixed pole respectively drive the top grinding disc and the bottom grinding disc to rotate. Before starting the motor, the pin can be pulled out from the inside of the fixed pole according to the outer diameter of the street light pole to be polished, and the vertical position of the top grinding disc can be adjusted up and down along the fixed pole to control the grinding pressure. When the top grinding disc moves to the specified position, the pin is inserted. During this process, the adjusting screw is controlled to slide left and right along the inside of the slide slot by loosening and tightening the adjusting screw to prevent the belt from falling off and ensure stable operation of the equipment.
[0018] 2. The utility model is provided with a clamping device. When the equipment is in use, the conical seat is fixed on the top of the base. As the polished end of the street light pole is inserted into the gap between the two plywood plates, the dead weight of the street light pole will press the vertical telescopic rod to slide downward along the inner wall of the conical seat, and the vertical telescopic rod drives the left end of the guide strip to slide downward. During this process, the top end of the vertical telescopic rod retracts downward under the squeezing of the street light pole, and the hydraulic oil inside the vertical telescopic rod is injected into the inside of the horizontal telescopic rod. The horizontal telescopic rod is extended to push the connecting rod to rotate a certain angle. The rotating connecting rod drives the plywood to deflect slightly, so that the ball bearings are placed on both sides of the street light pole. As the street light pole moves and is polished, the ball head at the bottom rolls, and the street light pole can slide smoothly left and right by reducing frictional resistance. The clamping device can prevent the street light pole from deviating during the left and right movement, thereby causing the weld to be unable to be polished. BRIEF DESCRIPTION OF THE DRAWINGS
