Description

Technical Field

[0001] This utility model relates to the field of bevel grinding technology for square tubes, and more specifically, it relates to a bevel grinding device for square tubes used in power transmission towers. Background Technology

[0002] Transmission line towers are generally classified into five types according to their shape: goblet-shaped, cat-head-shaped, T-shaped, dry-shaped, and barrel-shaped. According to their purpose, they are classified into tension towers, straight-line towers, angle towers, transposition towers (towers for changing the phase position of conductors), terminal towers, and crossing towers. Square tubes are used on power transmission towers. Usually, bevels are cut into the square tubes, and after cutting, the burrs on the bevels need to be polished.

[0003] When grinding the beveled corners of square tubes used in power transmission towers, people usually hold the tube by hand, bringing the beveled corner close to a motor-driven grinding disc. The grinding disc grinds the beveled corners of the tube. Because it is difficult for people to control the tube stably by hand, the tube tends to tilt during grinding, affecting the grinding effect. In addition, iron filings are generated during the grinding process, which fly everywhere and can easily cause injury to workers. Utility Model Content

[0034] In summary, when using the overall equipment:

[0035] The second motor 29 drives the screw 28 to rotate, causing the convex seat 27 to slide inside the convex groove 26. The convex seat 27 drives the horizontal seat 6, the round seat 7, the fixed seat 13, and the grinding disc 16 to move, adjusting the grinding disc 16 to the appropriate position. Then, the protective door 24 is opened, and a hand is placed inside the protective box 17. The first screw 10 is loosened to separate the locking pin 11 from the locking groove 12. Then, the fixed seat 13, the vertical seat 14, the first motor 15, and the grinding disc 16 are rotated to adjust the grinding disc 16 to a suitable angle. Finally, the first screw 10 is tightened. Insert the locking pin 11 into the corresponding locking slot 12 to fix the rotating base 9, the fixing base 13, and the grinding disc 16. Then close the protective door 24 and fix it with the door pin. Then, use multiple electric cylinders 4 to push the second positioning plate 5 to move and adjust the distance between the first positioning plate 3 and the second positioning plate 5 so that the distance between the first positioning plate 3 and the second positioning plate 5 is equal to the side length of the square tube. Then place the square tube in the middle of the first positioning plate 3 and the second positioning plate 5, and insert one end of the square tube into the interior of the protective box 17. At this time, the side end of the square tube is aligned with the side of the box. The first protective plate 18 is brought into contact with its side end. Then, the second screw 21 is loosened, and the side end of the second protective plate 19 is brought into contact with the side end of the square tube. The second screw 21 is then tightened to secure the second protective plate 19. The third screw 22 is then loosened, and the bottom end of the third protective plate 20 is brought into contact with the top end of the square tube. The third screw 22 is then tightened to secure the third protective plate 20. To prevent damage to the second and third protective plates 19 and 20 from the second and third screws 21 and 22, the side ends of the second and third screws 21 and 22 can be... The rubber head is fixedly connected so that it presses and fixes the second protective plate 19 and the third protective plate 20. Then, the square tube is pushed to move inward into the protective box 17 and the bevel on the square tube that needs to be ground comes into contact with the grinding disc 16. The grinding disc 16 grinds the bevel of the square tube. During this process, the first protective plate 18, the second protective plate 19 and the third protective plate 20 not only play a protective role, but also prevent the square tube from moving up, down and left and right. After grinding is completed, the square tube is pulled out, and then other square tubes are inserted into the interior of the protective box 17 for bevel grinding.
