[0055] According to the actual length of the steel pipe to be loaded, the distance between the two support assemblies is adjusted so that the steel pipe can be supported on the two support assemblies. The specific adjustment method is: start the servo motor 81 and the reducer 82, and drive the synchronous belt 10 to drive the adjustable support assembly 7 along the third linear guide rail 71 through the main pulley 8 and the slave pulley 9 until the distance between the two support assemblies is adapted to the length of the steel pipe.

[0056] Then, several steel pipes are placed on the two support components.

When the height of the steel pipe to be loaded exceeds the blocking portion 2, it falls along the inclined surface of the lifting member 31 to the corresponding production line. During this process, the next steel pipe rolls down the inclined surface of the support assembly to the loading station and becomes the next steel pipe to be loaded. This lifting operation is repeated, thereby realizing automatic and continuous loading of steel pipes.
