[0026] See also Figure 1-4 In this embodiment, a shot blasting rust remover with a limiting structure includes a shot blasting rust remover body 1, a transmission belt 3 is connected to the lower side of the shot blasting rust remover body 1, a rust removal mechanism for rust removal on the surface of steel structures of different thicknesses is arranged at the top of the shot blasting rust remover body 1, and a clamping and fixing mechanism for clamping the rust removal mechanism is arranged inside the shot blasting rust remover body 1. The rust removal mechanism includes a movable bracket 12 slidably sleeved on the top wall of the shot blasting rust remover body 1, three second springs 18 fixedly connected to the middle of the movable bracket 12, a driving motor 19 fixedly installed at the lower right end of the movable bracket 12, a cleaning roller 20 fixedly connected to the output end of the driving motor 19, and a height adjustment mechanism fixedly connected to the left side of the movable bracket 12. The height adjustment mechanism includes a connecting frame 8 fixedly connected to the lower left end of the movable bracket 12, two second support plates 9 fixedly connected to the connecting frame 8 away from the movable bracket 12, and a plurality of driving rollers 10 rotatably connected between the two second support plates 9.

[0027] Among them, the clamping and fixing mechanism includes two electric push rods 15 fixedly installed on the inner top wall of the shot blasting and rust remover body 1 and an arc-shaped clamping plate 17 fixedly connected to the output ends of the two electric push rods 15. A driving structure for height driving the electric push rods 15 is arranged outside the second support plate 9. The driving structure includes an object sensor 11 embedded on the lower side of the second support plate 9 and a sensor 16 embedded at one end of the two electric push rods 15. Three second springs 18 are arranged equidistantly in the horizontal direction. The top end of the movable bracket 12 passes through the top of the shot blasting and rust remover body 1 and extends to the outside. Two through holes 13 are opened on one side of the shot blasting and rust remover body 1. Two connecting frames 8 pass through the through holes 13 and extend to the outside. Multiple transmission rollers 10 are arranged equidistantly in the horizontal direction.

[0028] Embodiment 2:

[0029] See also Figure 1 and Figure 3 On the basis of the first embodiment, it includes a limiting mechanism arranged at one end of the shot blasting rust remover body 1 for limiting the steel structure, the limiting mechanism includes two first support plates 2 fixedly connected to the lower side of the front end surface of the shot blasting rust remover body 1, two first connecting rods 4 slidably sleeved on the inner sides of the two first support plates 2, a limiting plate 6 fixedly connected to one end of the two first connecting rods 4, two limiting rollers 7 rotatably connected to one side of the limiting plate 6, a second connecting rod 14 fixedly connected to one end of the limiting plate 6 close to the first connecting rod 4 and a first spring 5 sleeved on the outer side of the second connecting rod 14, the two limiting rollers 7 are arranged horizontally, and the two ends of the first spring 5 are respectively fixed on the opposite sides of the limiting plate 6 and the first support plate 2.

[0030] By adopting the above technical solution, when the steel structure passes through between the two limit plates 6 and contacts the surface of the limit roller 7, the limit roller 7 moves toward the first support plate 2 through the elastic action of the first spring 5 and the first connecting rod 4 and the second connecting rod 14 to expand the distance between the two limit plates 6. In cooperation with the rebound action of the first spring 5, the limit roller 7 contacts the left and right sides of the steel structure, thereby achieving the limitation of the left and right sides of steel structures of different shapes.

[0031] The working principle of the above embodiment is:

[0032] The steel structure is placed on the upper side of the transmission belt 3, and as it moves between the two limit plates 6, the limit rollers 7 are used to abut against the left and right surfaces of the steel structure. During this period, the first spring 5, the first connecting rod 4 and the second connecting rod 14 are used to limit the left and right sides of the steel structure, and the lower side of the upper transmission roller 10 of the steel structure abuts against the upper surface of the steel structure. When the steel structure is thicker, the steel structure abutted by the transmission roller 10 pushes up and moves the transmission roller 10. During this period, the movable bracket 12 connected by the connecting frame 8 moves upward synchronously, and the second spring 18 is also compressed and deformed synchronously to change the height of the transmission roller 10 and the cleaning roller 20 in the shot blasting rust remover body 1, and automatically realize height adjustment according to steel structures of different thicknesses. For the purpose of rust removal on the surface of the structure, after the steel structure moves away from the lower side of the driving roller 10, the object sensor 11 on the lower side of the second support plate 9 transmits information to the sensor 16 through electrical connection. At this time, the sensor 16 will start the arc-shaped clamping plate 17 at the output end of the electric push rod 15 to clamp the surface of the movable bracket 12 to prevent the movable bracket 12 from moving downward. Then the steel structure enters the inside of the shot blasting and rust removal device body 1, and the cleaning roller 20 at the output end of the drive motor 19 is started to rotate to remove rust from the surface of the steel structure. After rust removal, the steel structure moves out from the other end of the shot blasting and rust removal device body 1, and the arc-shaped clamping plate 17 is separated from the movable bracket 12 under the action of the electric push rod 15. The second spring 18 uses elastic action to restore the driving roller 10 and the cleaning roller 20 to their original positions.
