[0028] In a preferred embodiment, the automatic hanging and unloading mechanism 3 includes a shield 31. One end of the shield 31 is provided with a vertically penetrating slot 34. The two side walls of the slot 34 are arc-shaped surfaces. The opening of the slot 34 is larger on the outside and smaller on the inside. Openings are provided on both side walls of the slot 34 or on one side wall, which can be set according to actual situations and all fall within the protection scope of this application. The hook rod of the hook member 37 is exposed from one side opening. The inner side of the shield is a cavity structure, and a control mechanism for controlling the opening and closing of the hook member (37) is provided inside the cavity structure. The area enclosed by the hook rod of the hook member and the slot wall is the locking area for the round steel on the material cart.

[0029] The control mechanism includes a swing block 38, a pressure rod 39, a manual hanging and unloading operation port cover plate 310, an electric cylinder 40, a fixing plate 41, a first proximity switch 42, a second proximity switch 43, an arc-shaped hole 44, a tension spring 45, a detection piece 46, a first longitudinal plate 47, a second longitudinal plate 48, a longitudinal reinforcing rib 49, an L-shaped plate 410, and a proximity switch mounting plate 411.

[0030] One side of the fixing plate 41 is connected to the inner side of the shield 31. Two longitudinal reinforcing ribs 49 are arranged in parallel at intervals in the middle part of the other side of the fixing plate. The ends of the two longitudinal reinforcing ribs 49 are connected to one end of the L-shaped plate 410, and a U-shaped block 412 is connected to the L-shaped plate 410;

[0031] The hook member 37 includes a hook rod. One end of the hook rod is a hook, and the other end is provided with a shaft hole. The hook is exposed from the side wall opening of the slot. A tension spring connecting ear is arranged on one side of the shaft hole, and a pressing plate is arranged on the other side. A shaft is arranged in the U-shaped block 412, and the shaft passes through the shaft hole of the hook member 37, enabling the hook member 37 to rotate around the shaft. A first longitudinal plate 47 and a second longitudinal plate 48 are arranged on the side surface of the fixing plate 41 where the longitudinal reinforcing rib is provided, and the first longitudinal plate 47 and the second longitudinal plate 48 are respectively arranged on both sides of the longitudinal reinforcing rib 48.

[0032] The first longitudinal plate 47 is connected to the tension spring connection ear through a tension spring 45. The second longitudinal plate 48 is connected to the tail end of the electric cylinder 40. The piston rod of the electric cylinder 40 is connected to the lower end of a longitudinally arranged pressure rod 39. The upper end of the pressure rod 39 is rotatably connected to one side of the upper end of the swing block 38. A longitudinal axis is provided at the upper end of the U-shaped block 412. The other side of the upper end of the swing block 38 is rotatably connected to the longitudinal axis. The swing block 38 is driven to swing around the longitudinal axis by the telescopic movement of the electric cylinder 40. The pressing plate is located inside the pressure rod 39. When the electric cylinder 40 retracts, the pressure rod 39 can press the pressing plate to drive the hook member to rotate around the rotating shaft hole. A proximity switch mounting plate 411 is connected to the U-shaped block 412. An arc-shaped hole 44 is provided on the proximity switch mounting plate 411.
