Problems solved by technology

At present, manual docking is used, and the loading and unloading arm is operated to make the connecting pipe port close to the conveying pipe port of the tanker. The connecting pipe port of the loading and unloading arm is manually docked with the conveying pipe port of the tanker. Since the tanker is moored at sea and shakes with the waves , causing great difficulties to the docking operation, the docking operation process is complex, time-consuming, low work efficiency, and labor-intensive

Abstract

The invention discloses an automatic butt-joint device of an offshore fluid delivery pipeline interface and relates to the technical field of fluid loading-unloading devices. The automatic butt-joint device comprises two obliquely-arranged conical guide barrels with large downward ports, wherein one guide barrel is installed a delivery pipe of a tanker through a first installing rack, the other guide barrel is installed on a connecting pipe of a loading-unloading arm through a second installing rack, the two guide barrels are located on the same of the delivery pipe and the connecting pipe, and the guide barrel on the connecting pipe is located above one side of the guide barrel located on the delivery pipe. A winch is arranged on one side of the loading-unloading arm, a traction steel wire rope of the winch sequentially penetrates through the guide barrel on the connecting pipe and the guide barrel on the delivery pipe and is fixed to the first installing rack. Compared with the prior art, the automatic butt-joint device achieves butt joint of a connecting pipe port of the loading-unloading arm and a delivery pipe port of the tanker through gradual sleeving of the guide barrel on the connecting pipe and the guide pipe on the delivery pipe under the traction effect of the steel wire rope and is accurate in butt joint positioning and high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of fluid loading and unloading equipment, in particular to an automatic docking device for the interface of an offshore fluid delivery pipeline. Background technique [0002] The long-distance transportation of liquefied natural gas is mainly transported by tanker. When loading or unloading the ship, the delivery pipe of the tanker and the connecting pipe of the loading and unloading arm must be connected. At present, manual docking is used, and the loading and unloading arm is operated to make the connecting pipe port close to the conveying pipe port of the tanker. The connecting pipe port of the loading and unloading arm is manually docked with the conveying pipe port of the tanker. Since the tanker is moored at sea and shakes with the waves , causing great difficulties to the docking operation, the docking operation process is complex, time-consuming, low work efficiency, and labor-intensive.
