When the impurities adsorbed on the surface of the tensioning jack 1 are removed, the double-axis motor 311 is operated to drive the threaded screw 32 to rotate. When the threaded screw 32 rotates, the slider 33 is driven to move through the slip ring 331. When the slider 33 moves, it drives the cleaning plate 332 to move. The cleaning plate 332 is in contact with the surface of the tensioning jack 1, and then when the cleaning plate 332 moves, the impurities adsorbed on the surface of the tensioning jack 1 are removed, thereby achieving the purpose of improving the cleaning efficiency.

[0028] Embodiment 2
[0029] like Figure 1 , Figure 2 and Figure 4 As shown, a prestressed tensioning device for a steel structure proposed by the utility model is another implementation mode of the utility model compared to Example 1.

When the moving component 12 moves, the guide plate 22 is driven to move through the connecting block 223. When the guide plate 22 moves inside the square groove 2, the guide plate 22 cooperates with the square groove 2 to guide the connecting block 223, and then limit the moving component 12, so that the moving component 12 can move smoothly.

When the impurities adsorbed on the surface of the tensioning jack 1 are removed, the double-output shaft motor 311 is operated to drive the threaded screw 32 to rotate. When the threaded screw 32 rotates, the slider 33 is driven to move through the slip ring 331. When the slider 33 moves, the cleaning plate 332 is driven to move.
