Description

Technical Field

[0001] The utility model relates to a pipeline butt joint technology, in particular to a pipeline quick butt joint device. Background Art

[0002] The powder conveying pipeline and the silo pipe need to be quickly connected. The traditional structure cylinder is welded to the cylinder legs and the cylinder upper plate. When the cylinder is extended, the cylinder upper plate is parallel to the ground and has no freedom. The cylinder lower plate on the silo pipe is limited by the level of the ground, and it is difficult to ensure that the cylinder lower plate is completely parallel to the ground, so that the cylinder upper plate and the cylinder lower plate cannot be seamlessly connected, and there is a gap in the docking surface, resulting in leakage. After the improvement, the cylinder is connected to the cylinder legs and the cylinder upper plate by a universal connector. When the cylinder is extended, the cylinder upper plate still has freedom. When the cylinder lower plate is docked, it can self-compensate for the deflection of the cylinder lower plate caused by the uneven location, so that the cylinder upper plate and the lower plate are completely fitted, which can meet the needs of quickly transporting materials to the silo, and there will be no leakage at the interface during the transport. This device meets the above requirements. Utility Model Content

[0005] Furthermore, the number of the cylinder legs is 2-4, and correspondingly, the number of the cylinders is 2-4.

[0006] Furthermore, a universal joint is provided at the connection between the cylinder and the cylinder legs.
