Description
Technical Field
[0001] The utility model relates to the field of rust removal of steel structures, in particular to a rust removal device for the inner corner surface of a steel structure. Background Art
[0002] Steel structure has become a commonly used structural form due to its advantages such as light weight, high strength, strong tensile and compressive resistance, and convenient construction. During the use of steel components, since steel components generally need to be assembled on the construction site and then sprayed with anti-rust paint, they need to be stored after production and then transported uniformly. However, due to the erosion of moisture in the air environment, some steel components often rust during storage. Therefore, before being packaged and shipped out of the factory, the rusted steel components are generally polished and rust-removed. However, conventional manual tools such as wire discs and steel grinding heads are not easy to use. It is often impossible to thoroughly remove rust from the inner negative angle surfaces of steel components. Although the conventional steel grinding heads have good surface treatment effects, it is difficult to reach the dead corners of the negative angle surfaces. When using steel grinding heads or brushes for treatment, it is also necessary to exchange tools back and forth, which increases the difficulty and time of construction. Although the wire reel can reach the dead corners, its surface treatment roughness does not meet the grinding standards required by national regulations. At the same time, it is easy to damage the chamfers of the inner negative angle surfaces of steel components and affect the stress distribution. Therefore, we propose a rust removal device for the inner corner surfaces of steel structures to solve the above-mentioned problems. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] In actual use, people can place the bent angle I-beam on the top of the machine body, first fit the inner negative angle surfaces of the two bent angle I-beams with the grinding head, and then align the two ends of the bent angle I-beam. At this time, starting the vacuum pump inside the machine body can extract the gas inside the roller, and the bent angle I-beam can be adsorbed and fixed through the walking frame on the roller, which is convenient for subsequent grinding and rust removal. The motor inside the fixing frame can drive the bottom mounting frame to rotate, and the mounting frame can drive the outer connecting frame to rotate synchronously. The grinding block on the outside of the connecting frame can realize the grinding and rust removal of the inner negative angle surfaces of the bent angle I-beams that are in contact with the front and rear parts. By grinding the front and rear two bent angle I-beams at the same time, the four working strokes originally required for grinding and rust removal of two bent angle I-beams separately can be reduced to two working strokes, so that the work efficiency is doubled, which is beneficial to the mass production of production-oriented enterprises.
[0016] By using rollers to adsorb and fix the angled I-beams, the time wasted in loading and unloading with traditional clamping tools can be greatly reduced, and at the same time, damage to the surface of the angled I-beams by the clamping tools can be effectively avoided. By designing the rollers to have square end faces, the stability of the angled I-beams on the rollers can be effectively improved, so that the angled I-beams can be fixed more stably. At the same time, the reduction motor and transmission chain group at the ends of the rollers can drive the rollers to rotate. Before and after grinding and rust removal, people can start the reduction motor, and the rollers can assist in loading and unloading the angled I-beams, thereby greatly reducing the labor intensity of the staff. By setting the edges of the rollers to be rounded, the angled I-beams can be more stable when being transmitted, which is beneficial to practical use.
[0017] In the actual grinding and rust removal process, the stepper motor inside the machine compartment can drive each driving gear to rotate, and the driving gear can drive the meshing transmission gear on one side to rotate synchronously, and the transmission gear can use the meshing tooth groove on the other side to drive the guide bar to move. Since the upper and lower driving gears turn in opposite directions, the upper and lower guide bars and the upper and lower racks can move in opposite directions, thereby adjusting the grinding range of the grinding head, so that the grinding head can adapt to angled I-beams of different heights during grinding, which is conducive to grinding different types of angled I-beams in actual production, avoiding the operating steps of replacing the grinding head, and making the equipment operation simpler and more practical.
[0018] The grinding block can be installed on the upper frame and the lower frame through the mounting groove. The grinding block is designed to be detachable, and the grinding block can be replaced according to the material of the curved angle I-beam and the degree of rust consolidation during actual use, which is conducive to coping with different usage scenarios. At the same time, the fixed frame is designed to be a single-sided ring and a multi-side block superposition design, so that while ensuring the grinding efficiency, the use of abrasives can be effectively reduced, thereby effectively reducing the investment in production costs, and the single-sided ring and the side block of the grinding block can simultaneously realize the grinding of the inner negative angle side surface and the upper and lower surfaces of the curved angle I-beam, so that there is no need to adjust the grinding angle of the curved angle I-beam and the grinding head, and only the inner negative angle surface of one side of the curved angle I-beam can be completely ground. Compared with traditional fixed grinding blocks and grinding belts, it is more practical and more convenient to operate, so that a single grinding stroke only needs to run one grinding track, thereby greatly improving the actual production efficiency.
[0019] During grinding, the bristles on the single-sided ring of the grinding block can be used to clean the upper and lower inner angle surfaces after grinding, preventing rust debris from sticking to the plane, eliminating the subsequent cleaning steps and preventing the accumulated rust debris from affecting the subsequent grinding and rust removal work, and causing damage to the grinding block and the polished inner angle surfaces, which is beneficial to the grinding of long curved I-beams.
[0020] The corners of the single-sided ring of the grinding block are changed to an inlaid grinding ring. The soft grinding ring can grind the curved I-beam at high speed while having a certain degree of deformability, thereby preventing the hard abrasive from damaging the chamfers of the two contacting sides of the inner female angle of the curved I-beam and affecting the stress distribution of the curved I-beam. This can truly achieve non-destructive rust removal of the curved I-beam, which is beneficial to actual use. During grinding, the air pump inside the mounting frame can draw air and discharge it through the spray hole, and the high-pressure airflow sprayed through the spray hole can blow off the rust produced by grinding the curved I-beam, which is beneficial to actual use.
