[0002] In the processing of stainless steel pipes, long tubular stainless steel pipes are centrally transferred to a storage location for stacking after production. However, the current transfer tool is a traditional cart. After a certain number of stainless steel pipes are placed, they are transported to a designated location by the cart. Then, the stainless steel pipes are taken off the cart by a crane mechanism and turned to the same location as the stacking location before being lowered. However, during the turning process of the crane, the stainless steel pipes are in a suspended state, making it inconvenient to turn, and shaking can easily cause collision damage to surrounding equipment or personnel.

The rotating shaft 2 is rotatably mounted at the bottom of the frame, and the gear 2 is fixedly arranged on the rotating shaft 2, and the number of the gears 2 is consistent with the number of the gears 1 on the corresponding side. The gear 1 on the rotating shaft 1 is meshed with the gear 2 on the rotating shaft 2 in a one-to-one correspondence. The driving motor 1 and the reducer are respectively mounted at the bottom of the frame, and the rotating shaft of the driving motor 1 is connected to the input end of the reducer, and the output end of the reducer is connected to the rotating shaft 2.

[0030] A steering mechanism is provided between the rail car and the lower side of the frame, and the steering mechanism includes a control turntable, a fixed frame and a second drive motor. The turntable is rotatably mounted on the rail car, the second drive motor is mounted on the rail car, and a rotating shaft of the second drive motor is arranged corresponding to the side of the turntable. The fixed frame is mounted on the upper side of the turntable, and the storage rack is mounted on the fixed frame. A rack is arranged in a circle around the side of the turntable, and a third gear is mounted on the rotating shaft of the second drive motor, and the third gear is meshed with the rack.
