[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1 to 8The steel structure grinding device shown includes a lifting assembly 1, a guide assembly 2, and a grinding assembly 3. The lifting assembly 1 drives the guide assembly 2 and the grinding assembly 3 to move vertically, thereby grinding the column to be ground within a certain range along its length. Of course, if the length of the column to be ground is greater than the travel distance of the lifting assembly 1, a support rod can be used to raise the installation height of the lifting assembly 1, increasing the grinding range. In this embodiment, the column to be ground is cylindrical.

[0029] The lifting assembly 1 includes a base 10, a frame 11, a connecting block 12, a lead screw 13, and a vertical drive motor 14. The frame 11 is fixedly installed on one side of the top of the base 10, reducing the distance between the grinding assembly 3 and the column to be ground, thus avoiding positional interference between the base 10 and the column and affecting actual use. The base 10 is a square steel plate. Multiple auxiliary fixing plates 17 are provided on the base 10. In actual fixing, the base 10 can be laid flat on the ground and a weight can be pressed onto the top of the base 10, or it can be fixed to the ground using expansion bolts. At the same time, the lifting assembly 1 can be tied to the column to be ground through the auxiliary fixing plates 17 for further auxiliary fixing, improving the reliability of the base 10's fixation.

[0030] The lead screw 13 is rotatably mounted inside the frame 11. A vertical drive motor 14 is fixedly mounted on the top of the frame 11 by fasteners. The vertical drive motor 14 drives the lead screw 13 to rotate. Specifically, both ends of the lead screw 13 are rotatably mounted inside the frame 11 via bearings 15. The output end of the vertical drive motor 14 is fixedly connected to the lead screw 13 via a coupling 16. When the vertical drive motor 14 is energized and rotates, it drives the lead screw 13 to rotate via the coupling 16. The vertical drive motor 14 is a stepper motor.

[0031] The connecting block 12 is slidably mounted on the frame 11, and the lead screw 13 drives the connecting block 12 to move vertically along the frame 11. In this embodiment, the connecting block 12 is a steel plate, and a lead screw nut slider is fixedly mounted on the back of the steel plate. The lead screw nut slider is poweredly connected to the lead screw 13, and the lead screw nut slider is slidably mounted on the frame 11. When the lead screw 13 rotates, it drives the lead screw nut slider to slide along the frame 11.

[0032] The guide assembly 2 is used to drive the grinding assembly 3 to move along the length of the column to be ground. The guide assembly 2 includes a support frame 20, a spring 21, a connecting column 22, a guide ring 23, and a guide wheel 24. The support frame 20 includes two support units that are hinged together, and a locking element 25 is provided at one end of the two support units facing each other; the two support units can rotate around the hinge axis, and the locking element 25 is a bolt, which locks the two support units at one end facing the hinge axis.

[0033] The support frame 20 is fixedly mounted on the connecting block 12 by fasteners. When the connecting block 12 moves, it drives the support frame 20 to move. Multiple sets of springs 21 are fixedly installed inside the support frame 20. Each set of springs 21 has two springs. Guide wheels 24 are installed on the other end of the springs 21 via guide wheel brackets. When the column to be ground is installed inside the support frame 20, the guide wheels 24 are pressed against the outer surface of the column to be ground under the pressure of the springs 21, so that the grinding component 3 fits better against the outer surface of the column to be ground, thus improving the grinding quality.

[0034] The connecting column 22 is fixedly installed at the bottom of the support frame 20, and the guide ring 23 is fixedly installed at the bottom of the connecting column 22. The guide ring 23 is composed of two arc-shaped units spliced ​​together. When the two support units open, the two arc-shaped units open accordingly, and when the two support units close, the two arc-shaped units close accordingly.

[0035] The grinding assembly 3 is used to grind the outer surface of the column to be ground; the grinding assembly 3 includes a lower support 30, a rotary drive motor 31, a grinding drive motor 32, and a grinder 33. The rotary drive motor 31 is fixedly installed on one side of the lower support 30, and the rotary drive motor 31 is powered by the guide ring 23. When the rotary drive motor 31 is energized and rotates, it drives the lower support 30 to rotate around the guide ring 23.

[0036] The rotary drive motor 31 is poweredly connected to the guide ring 23 via a gear set. The gear set includes an internal gear 26 fixedly or integrally disposed within the guide ring 23 and a drive gear 27 fixedly mounted on the output end of the rotary drive motor 31. The drive gear 27 meshes with the internal gear 26. When the rotary drive motor 31 is energized and rotates, it drives the drive gear 27 to rotate. Through the meshing of the drive gear 27 with the internal gear 26, the guide assembly 2 rotates along the internal gear 26.

[0037] In a preferred embodiment, to improve the stability of the guide assembly 2 rotating along the internal gear 26, a slide rail is provided on the guide ring 23, and a slider is rotatably provided on the output end of the rotary drive motor 31, sliding within the slide rail. Alternatively, the slider can be mounted on the housing of the rotary drive motor 31 or on the lower bracket 30.

[0038] The grinding drive motor 32 is fixedly installed on the other side of the lower bracket 30. The grinding drive motor 32 is powered by the grinder 33. After being powered, the grinding drive motor 32 drives the grinder 33 to rotate and perform grinding operations.

[0039] The grinder 33 includes a drive pulley 330, a driven pulley 331, a toothed belt 332, and a grinding wheel 333. The drive pulley 330 is fixedly mounted on the output shaft of the grinding drive motor 32. Two driven pulleys 331 are provided and are rotatably mounted on the lower bracket 30. The drive pulley 330 is poweredly connected to the two driven pulleys 331 through the toothed belt 332.

[0040] The grinding wheel 333 is connected to the driven pulley 331 via a connecting shaft. When the grinding drive motor 32 is energized and rotates, the drive pulley 330 rotates accordingly, and drives the two driven pulleys 331 to rotate through the toothed belt 332, so that the grinding wheel 333 can perform the grinding operation.

[0041] In a preferred embodiment, an abrasive belt is provided on the outer side of the toothed belt 332. When the toothed belt 332 is driven, the outer abrasive belt can also polish the column to be polished. For columns of different sizes to be polished, the installation position of the driven pulley 331 can be adjusted within a certain range, and the toothed belt 332 of the corresponding length can be replaced, which has a certain adaptability.

[0042] A microcontroller program controller is set on the base 10 or frame 11. The microcontroller program controller controls the rotation direction, speed and start / stop of the grinding drive motor 32, the rotary drive motor 31 and the vertical drive motor 14, so that the above three motors can work according to the set parameters to complete the grinding of the column. The microcontroller program controller is a 32 series microcontroller with model STM32F103C8T6.

[0043] The specific method of using this device is as follows:

[0044] Step 1: Equipment assembly. First, fix the lifting component 1 so that the grinding component 3 can fit snugly against the column to be ground. At the same time, the auxiliary fixing plate 17 can be used to reinforce and fix the entire lifting component 1 to prevent the lifting component 1 from shaking and affecting the grinding effect.

[0045] Open the support frame 20 so that the column to be polished is located inside the support frame 20. Then install the polishing component 3 on the guide ring 23. Finally, fix the support frame 20 with the locking component 25. At this time, the polishing component 3 is attached to the column to be polished.

[0046] Step two, grinding operation: Power on the grinding drive motor 32 and the rotary drive motor 31 to make the grinder 33 rotate rapidly. Driven by the rotary drive motor 31, the grinder 33 rotates slowly around the column to be ground, grinding the circumference of the column. After one revolution, the grinding assembly 3 is raised or lowered to a certain height using the lifting assembly 1, and the grinding operation is repeated. After grinding is completed, simply remove the locking part 25 to quickly separate the support frame 20 from the column to be ground, and finally disassemble and store the device.

[0047] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
