The quality of the internal partition plate often affects the mechanical properties of the column itself and thus affects the safety of the entire building.

[0003] Before the electroslag strip is assembled, it needs to be polished to remove the surface cutting slag. The electroslag strip has a slender rectangular strip structure. Workers need to polish the edges of the electroslag strip smoothly, and the consumption is extremely large. The manual method is economically poor, and it is very easy for workers to hold the polishing tool to cause danger. Summary of the Invention

It can not only perform shot peening on the sorted electroslag strips through a particle spraying device to remove the slag adhering to the surface of the electroslag strips, but also strengthen the surface of the electroslag strips to facilitate subsequent welding. At the same time, through the stepping mechanism, the polished electroslag strips can be automatically transported into the robot working position without manual sorting, reducing the labor intensity of manual operation.

[0070] During the process of the lifting and transfer mechanism 6 swallowing the electroslag strip, the electroslag strip is clamped by the transfer trolley 8 at this time. The lifting and transfer mechanism 6 moves downward. When the tip 6106 of the spoon-shaped member 6104 abuts against the electroslag strip, it rotates around the rotation axis. The tip 6106 of the spoon-shaped member 6104 withdraws from the cavity 6102. When the electroslag strip passes through, the rotation axis is pulled back, and the tip 6106 of the spoon-shaped member 6104 returns to the cavity 6102 again and plays a blocking effect on the electroslag strip.

[0071] When the lifting and transfer mechanism 6 continues to descend, when the pendant 6108 contacts the lower stepping mechanism 7, the pendant 6108 contacts the protrusions on both sides, driving the spoon-shaped member 6104 to rotate, and the tip 6106 retracts, and the electroslag strip falls into the groove 706.

The support tabletop 707 is connected to the second slide rail 711 through a second slider 712. A first rotating seat 713 is provided on the support tabletop 707. The first rotating seat 713 is connected to a second rotating seat 715 through a connecting rod 714. Positioning blocks 716 are symmetrically provided on both sides of the second rotating seat 715. The positioning blocks 716 are connected to the stepping tabletop 705 through support members 717. The stepping tabletop 705 is located between two fixed tabletops 704. Grooves 706 are evenly provided on the stepping tabletop 705 and the fixed tabletops 704. A waist-shaped hole 702 is provided on the side surface of the second frame body 701. The second rotating seat 715 passes through the positioning blocks 716 through a connecting shaft 703 and is limited in the waist-shaped hole 702 and moves along the waist-shaped hole 702. The support tabletop 707 is driven by the cylinder 709 through the piston rod 710 to make a reciprocating movement along the second slide rail 711, and then the connecting rod 714 is pushed to move along the waist-shaped hole 702. The descending height of the stepping tabletop 705 is the vertical projection of the moving distance of the connecting rod 714 along the waist-shaped hole 702, and the horizontal moving distance of the stepping tabletop 705 is the horizontal projection of the moving distance of the connecting rod 714 along the waist-shaped hole 702, that is, each step is the distance of an adjacent groove 706. The first rotating seat 713, the second rotating seat 715, the positioning blocks 716, and the support members 717 improve the stability and reliability of the stepping tabletop 705 during movement. The grooves 706 facilitate the stepping conveyance of the processed electroslag bars.

[0074] There are grooves 706 on the stepping tabletop 705. When the rotating shaft moves from point C to point D, its horizontal component is the horizontal distance of the groove 706 moving from point C to point D, and its vertical component is the vertical distance of moving from point C to point D. Those skilled in the art can design the stepping mechanism 7 at different angles according to their own situations.

[0075] The grooves 706 on the stepping tabletop 705 are arranged in sequence to lift the electroslag bars forward one by one and are finally picked up by the robot, realizing the automatic processing and conveying of the electroslag bars.

[0076] Through the design of the above structure, not only can the sorted electroslag bars be shot peened by the particle spraying device 5 to remove the slag hanging on the surface of the electroslag bars, but also the surface of the electroslag bars can be strengthened, facilitating subsequent welding. At the same time, through the stepping mechanism 7, the polished electroslag bars can be automatically conveyed into the robot work position without manual sorting, reducing the labor intensity of manual operation.

[0077] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to achieve substantially the same technical effects are all covered by the protection scope of the present invention.
