[0055] Working principle and technical effect of the present invention:

[0056] The bundled steel bars are placed on the steel bar support platform structure 7, and the horizontal distance adjustment component 3 adjusts the distance between the two slings 2. When the distance between the two slings 2 is adjusted to the maximum, the vertical distance adjustment component 4 adjusts the height of the two slings 2 downward, so that the bottom side height of the sling 2 is lower than the bottom side height of the steel bar. The horizontal distance adjustment component 3 adjusts the distance between the two slings 2 so that the two slings 2 are close to each other, and the two ends of the steel bar are nested by the two slings 2. The vertical distance adjustment component 4 adjusts the height of the two slings 2 upward, so that the steel bar is suspended from the steel bar support platform structure 7.

[0057] The two first hydraulic cylinders 402 of the vertical distance adjustment assembly 4 are respectively telescopically adjusted, that is, when the push rod of one of the first hydraulic cylinders 402 is extended, the push rod of the other first hydraulic cylinder 402 is retracted, thereby realizing the turning of the steel bar in the hanging ring 201. At this time, the sandblasting head 607 of the sandblasting pipeline structure 6 moves along the length direction of the steel bar under the drive of the linear moving guide rail assembly 5, thereby realizing all-round sandblasting and rust removal of the steel bar; wherein, the push rods of the third hydraulic cylinders 801 of the two end pushing structures 8 are extended, thereby driving the two push plates 803 to approach each other, and the two push plates 803 push the two ends of the steel bar along the middle, so that the two ends of each steel bar are flush with each other;

[0058] After rust removal is completed, the vertical distance adjusting component 4 adjusts the height of the two slings 2 downward. When the steel bar falls on the steel bar support platform structure 7 for support, the bottom side height of the sling 2 is lower than the bottom side height of the steel bar. Then the horizontal distance adjusting component 3 adjusts the spacing between the two slings 2 so that the two slings 2 are away from each other. The two slings 2 are separated from the two ends of the steel bar, and the steel bar after rust removal is removed from the steel bar support platform structure 7.
