Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation, and more specifically, to a steel pipe loading and unloading machine. Background Art

[0002] Steel pipe loader is a kind of mechanical equipment specially used for loading and unloading long materials such as steel pipes. It usually includes lifting gantry, lifting crane, lifting main arm, telescopic arm and other components. These components work together to efficiently and safely load and unload steel pipes. It is mainly used in environments where steel pipes need to be frequently loaded and unloaded.

[0003] Most of the existing steel pipe loading and unloading machines are equipped with a clamping device to clamp the steel pipe for transportation. However, since the cross-section of the solid steel pipe is circular and the clamp cannot be inserted into the steel pipe, when clamping the outer surface of the solid steel pipe, the clamp of the existing clamping device needs to wrap the outer surface of the steel pipe. The solid steel pipe needs to be placed on a bracket so that the outer surface of the steel pipe is a certain distance from the ground to facilitate the existing steel pipe disassembly machine to clamp it. When placed on the ground, the clamping device is not easy to clamp, which makes it inconvenient for the disassembly machine to clamp the solid steel pipe close to the ground.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a steel pipe loading and unloading machine. Utility Model Content
