[0025] like Figure 1 and Figure 2As shown, the rust removal device for the surface of a steel structure comprises: a first roller brush 8, a second roller brush 4, a first drive assembly and a second drive assembly; the first roller brush 8 is provided with a first rotating shaft, the drive end of the first drive assembly is connected to one axial end of the first rotating shaft, for driving the first rotating shaft to rotate along its axial direction, and the radial side wall of the first rotating shaft is ringed with first bristles, and the axial cross-section of the first bristles along the first rotating shaft is rhombus-shaped; the second roller brush 4 is provided with a second rotating shaft, the drive end of the second drive assembly is connected to one axial end of the second rotating shaft, for driving the second rotating shaft to rotate along its axial direction, and the radial side wall of the second rotating shaft is ringed with an annular second bristle, the annular inner wall of the second bristle is fixedly sleeved on the rotating shaft, the annular outer wall of the second bristle is provided with an annular groove, and the annular groove adopts a V-groove matching the angle steel.

[0026] The device for removing rust from the surface of steel structure parts proposed in this embodiment is simple in setting and can meet the purpose of removing rust from the surface of steel structure by the implementers in this field. By transporting the angle steel 7 from the material discharge pile to the loading device through the roller conveyor 14, during this transportation, a process of removing rust from the surface of the angle steel 7 is added, so that the first roller brush 8 contacts the surface of one side of the angle steel 7, and the second roller brush 4 contacts the surface of the other side of the angle steel 7, and the first drive assembly and the second drive assembly drive the first rotating shaft and the second rotating shaft respectively, so that the first roller brush 8 and the second roller brush 5 rotate at high speed, and the rotation gap between the first brush bristles and the second brush bristles matches the size of the angle steel, so that the rust on the surface of the angle steel 7 can be removed. In order to better allow the first roller brush 8 and the second roller brush 4 to contact the surface of the angle steel 7, an additional set of support springs 5 ​​is set between the spring seat and the bearing connecting the first roller brush 8 and the second roller brush 4 to the support part, so that the elastic force of the support spring 5 always presses the first roller brush 8 and the second roller brush 4 to contact the surface of the angle steel 7, thereby improving the rust removal effect. After the rust is removed, the paint on the surface of the angle steel 7 after color coating is more firmly combined with the angle steel 7, the paint is not easy to fall off, and the anti-corrosion effect is obvious. And if the angle steel 7 needs to be pickled for surface galvanizing, the pickling speed of the angle steel 7 after rust removal is increased, thereby improving production efficiency; the rust removal work of the angle steel 7 is carried out in a relatively closed space, and the rust dust is sucked away and removed by the dust collector 13.

[0027] In one specific embodiment, a rotation gap is provided between the first bristles and the second bristles, and the angle steel 7 is suitable for being inserted into the rotation gap, and the rhombus-shaped vertex of the first bristles matches the annular groove of the second bristles, and the rhombus-shaped vertex of the first bristles can extend into the annular groove of the second bristles.

In this embodiment, it should be noted that in order to better allow the first roller brush 8 and the second roller brush 4 to contact the surface of the angle steel 7, a support spring 5 is added between the spring base of the support part and the bearing seat, and is tightened with a locking bolt and a locking nut 9, and the size of the elastic force is adjusted so that the elastic force always presses the first roller brush 8 and the second roller brush 4 to contact the surface of the angle steel, thereby improving the rust removal effect.
