During use, the position of the square collar ring 15 and the length of the second telescopic rod 19 are adjusted according to the size of the hollow round steel. Subsequently, the length of the third electric telescopic rod 102 is adjusted so that the second support column 104 extends into the hollow round steel. The fourth electric telescopic rod 1 is started. At this time, the fourth electric telescopic rod 1 extends, and the end of the fourth electric telescopic rod 1 abuts against the inner wall of the hollow round steel. Through the symmetrically arranged first electric telescopic rods 13, hoisting ropes 17, third electric telescopic rods 102 and a plurality of fourth electric telescopic rods 1 fixedly connected to the side wall of the second support column 104, clamping of the inner wall of the hollow round steel workpiece is realized, and the stability of the hollow round steel workpiece during hoisting is increased.

At this time, the elastic pull rope 2 will exert a reaction force on the electric reel 16 and the connecting platform 101, increasing the stability of the second telescopic rod 19. The stretching of the fourth electric telescopic rod 1 drives the movement of the elastic sheet 3. When the surface of the elastic sheet 3 contacts the inner wall of the hollow round steel workpiece, it deforms. The fourth electric telescopic rod 1 continues to extend so that the elastic sheet 3 fits the inner wall of the hollow round steel. By providing the elastic sheet 3, the contact area between the end of the fourth electric telescopic rod 1 and the inner wall of the hollow round steel workpiece is increased, further enhancing the support and clamping effect on the inner wall of the hollow round steel workpiece. Start the air pump 41. At this time, the air pump 41 generates air flow and then sprays out from the air jet head 4. By providing the air jet head 4 and the air pump 41, the inner wall of the hollow round steel workpiece can be purged, reducing the rust and impurities on the inner wall of the hollow round steel, making the elastic sheet 3 better fit the inner wall of the hollow round steel workpiece, and reducing the dislocation and sliding of the hollow round steel workpiece. Through the symmetrically arranged backing plates 5, clamping of the end cross-section of the hollow round steel workpiece is achieved, increasing the stability of the hollow round steel workpiece during the lifting process. By providing the second rubber block 6, the friction between the backing plate 5 and the end cross-section of the hollow round steel can be increased, reducing the dislocation and sliding of the hollow round steel.
