Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an exterior paint polishing device for a steel structure bridge workshop. Background Art

[0002] Steel is a material of a certain shape, size and performance made from steel ingots, steel billets or steel through pressure processing. Most steel processing is done through pressure processing, which causes the processed steel (billets, ingots, etc.) to undergo plastic deformation. In order to ensure the appearance of the steel structure, different colors of paint or anti-corrosion paint will be sprayed on the outside.

[0003] During the production process of steel structures, in order to remove the burrs and surface impurities generated during the processing of steel, the steel must be polished. The existing polishing device is inconvenient for workers to fix different steels. Since the diameters of different steel pipes are different, or when square steel pipes need to be polished, it is more troublesome to fix them. Utility Model Content

[0020] Reference Figure 1-5The utility model provides a steel structure 7 bridge workshop exterior paint polishing device 12: comprising a base 1, the upper end of the base 1 is provided with opposite support plates 2 on both sides; the left end of the base 1 is provided with a polishing device 12; the inner side of the support plate 2 is provided with a pulling plate 3; the upper ends of the two pulling plates 3 are provided with connecting plates 4; the middle part of the upper end of the connecting plate 4 is provided with a handle 5; the lower end of the connecting plate 4 is provided with a steel structure 7; the lower end of the steel structure 7 is provided with a tensioning assembly 6; the end of the pulling plate 3 close to the steel structure 7 is provided with a plurality of tensioning rods 8; a mounting plate 9 is provided at one end of the pulling plate 3 close to the steel structure 7; a plurality of friction rods 10 are provided at one end of the mounting plate 9 close to the pulling plate 3. When in use, the pulling plate 3 is moved upward in the supporting plate 2 by holding the handle 5 upward, thereby increasing the space between the tensioning assembly 6 and the connecting plate 4. The steel structure 7 is inserted from front to back between the connecting plate 4 and the tensioning plate through external equipment. When the steel structure 7 is installed, it can be manually pressed downward so that the connecting plate 4 fits with the steel structure 7, which can facilitate fixing and limiting it in this way.

[0021] As a further implementation scheme of the above technical solution: Figure 2-5 As shown, the tensioning assembly 6 includes a tensioning frame 601; the upper end of the tensioning frame 601 is provided with evenly distributed mounting holes 602; the upper left and right ends of the base 1 are provided with sliding grooves 603; the upper left and right sides of the tensioning frame 601 are provided with sliding rods 604, the lower end of the tensioning frame 601 is provided with a fixing ring 605, the inner side of the fixing ring 605 is provided with a damping rod 606, and the lower end of the fixing ring 605 and the lower end of the damping rod 606 are fixedly connected to the base 1, the upper end of the damping rod 606 is located at the middle of the lower end of the tensioning frame 601, the sliding rod 604 is located in the mounting holes 602 opened on the left and right sides of the fixing frame, and the sliding rod 604 is connected to the base 1. The fixing frame is fixedly connected, and the sliding rod 604 is located in the sliding groove 603 opened on the left and right sides of the base 1, and the sliding rod 604 is slidably connected to the base 1. When the steel structure 7 is inserted into the gap between the connecting plate 4 and the tensioning frame 601 in the tensioning assembly 6, as the connecting plate 4 is pressed down, the sliding rods 604 to be tested on both sides of the tensioning frame 601 are slightly offset in opposite directions in the sliding groove 603, so that the tensioning frame 601 is deformed and contacts downward with the damping rod 606 in the fixing ring 605, and the upper end of the tensioning frame 601 is supported by the damping rod 606 to prevent the steel structure 7 from being squeezed too hard and causing the tensioning frame 601 to deform excessively, resulting in an irreversible state.

[0022] As a further implementation scheme of the above technical solution: Figure 1-4As shown, the pulling plate 3 passes through the supporting plate 2, and the pulling plate 3 is slidably connected to the supporting rod, the pulling plate 3 is fixedly connected to the tensioning rod 8, and the mounting plate 9 is fixedly connected to the friction rod 10, the mounting plate 9 is fixedly connected to the supporting plate 2, and the friction rod 10 is tightly connected to the tensioning rod 8. When it is necessary to adjust the height of the connecting plate 4, the handle 5 is held and pulled upward. When the pulling force is greater than the damping between the friction rod 10 and the tensioning rod 8, the pulling plate 3 moves upward in the supporting rod, and the space between the connecting plate 4 and the tensioning assembly 6 is increased. In the state of no force, the tensioning rod 8 in the pulling plate 3 and the friction rod 10 in the supporting plate 2 fit each other, thereby fixing the position of the pulling plate 3 in the supporting plate 2, which is convenient for changing the height of the pulling plate 3 and adjusting the gap between the pulling plate 3 and the tensioning assembly 6.
