[0014] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0015] like Figure 1 , 2 , 3, and 4, a device for quickly cleaning rust on the surface of steel bars is used for removing rust from steel bars, comprising a rotating shaft base 1, a rotating shaft 2, a rotating cylinder 3, a fixing nut 4, a limiting steel plate 5, a fixing screw 6, a semicircular arc clamp 7, an electric drill 8, and a bowl-shaped wire wheel 9; the device for quickly cleaning rust on the surface of steel bars is connected to other devices through two rotating shaft bases 1, two rotating shafts 2 are arranged between the two rotating shaft bases 1, and rotating cylinders 3 are respectively sleeved on the two rotating shafts 2, so as to remove rust from the steel bars. Figure 1 It can be clearly seen from the figure that each of the two rotating shafts is respectively sleeved with a rotating cylinder 3, the rotating cylinder 3 is hollow, and is sleeved on the rotating shaft 2 and can rotate freely relative to the rotating shaft 2, so as to facilitate the subsequent pushing of the rusty steel bars forward; a fixing nut 4 is welded on the rotating shaft base 1 on one side, and a limiting steel plate 5 is provided on one side of the fixing nut 4, and the limiting steel plate 5 is connected to the fixing nut 4 through a fixing screw 6. It should be noted here that the fixing screw 6 penetrates the fixing nut 4 and cooperates with its thread; a semi-circular arc clamp 7 is provided on the rotating shaft base 1 on the other side, and an electric drill 8 is fixed on the semi-circular arc clamp 7, and a bowl-shaped wire wheel 9 is provided at one end of the electric drill 8.

[0016] A limiting steel plate 5 is provided on one side of the bowl-shaped wire wheel 9 , and a steel bar is provided between the bowl-shaped wire wheel 9 and the limiting steel plate 5 .

[0017] The electric drill 8 and the bowl-shaped wire wheel 9 are connected through the self-contained slotted hole, and the electric drill 8 drives the bowl-shaped wire wheel 9 to rotate when working; the lower end of the semicircular arc clamp 7 is welded and fixed to the rotating shaft base 1 near the position of the electric drill 8, and the semicircular arc clamp 7 fixes the end of the electric drill 8 by tightening the self-contained bolts; the rotating shaft base 1 is fixed to other devices by welding; the inner end of the fixed screw 6 is rotatably connected to the limiting steel plate 5. It should be supplemented here that there are many ways to achieve the rotatable connection between the inner end of the fixed screw 6 and the limiting steel plate 5, such as For example, the limiting steel plate 5 is close to the fixed bearing on one side of the fixing screw 6, and the inner end of the fixing screw 6 is inserted into the inner ring of the bearing and has an interference fit therewith; when the fixing screw 6 is turned, the fixing screw 6 generates a forward thrust or a backward pulling force on the limiting steel plate 6, and under the action of this thrust or pulling force, the limiting steel plate 5 moves along the length direction of the rotating shaft 2, and the limiting steel plate 5 limits the rusty steel bars, thereby improving the frictional rust removal efficiency between the rusty steel bars and the bowl-shaped wire wheel 9, and the overall device is combined into a device for quickly cleaning the rust on the surface of the steel bars.

[0018] The semicircular arc fixture 7 of the device for quickly cleaning the rust on the surface of the steel bar has a size that matches the end size of the electric drill 8 and is fixed by tightening the bolts provided on the semicircular arc fixture 7.

[0019] A device for quickly cleaning rust on the surface of a steel bar is provided, wherein a semicircular arc fixture 7, a rotating shaft 2 and a rotating shaft base 1 are fixed by welding to form a whole.

[0020] The specific construction steps are: first install the bowl-shaped steel wire wheel 9 of the device on the electric drill 8, unscrew the bolts of the semicircular arc fixture 7, put the electric drill 8 into the semicircular arc fixture 7, close the semicircular arc fixture 7 and tighten the bolts; place the rusty steel bar on the rotating cylinder 3 and close it to the bowl-shaped steel wire wheel 9; manually pass the fixing screw 6 through the fixing nut 4 and continuously screw it in until the limit steel plate 5 is close to the rusty steel bar, turn on the switch of the electric drill 8, and the bowl-shaped steel wire wheel 9 will start to rotate and rub the rusty steel bar with the electric drill 8. When the rusty steel bar has been cleaned within the range of the bowl-shaped steel wire wheel 9, push the rusty steel bar forward by hand, and the rotating cylinder 3 will rotate accordingly, which is convenient for the rusty steel bar to continue to be cleaned. Repeatedly push the rusty steel bar to complete the rust removal of the steel bar.

[0021] In this embodiment, the electric drill 8 of the device for quickly cleaning the rust on the surface of the steel bar and the matching bowl-shaped wire wheel 9 are connected through the self-contained slots, and the function is mainly based on the contact friction between the bowl-shaped wire wheel 9 and the rusted steel bar. The electric drill 8 can be replaced by a connector, one end of which is connected to the slot of the bowl-shaped wire wheel 9, and the other end of the connector is connected to the power source through a slot structure.
