Description

Technical Field

[0001] The utility model belongs to the technical field of oil and gas chemical terminals and relates to a hose lifting device for an oil and gas chemical terminal. Background Art

[0002] The floating dock is a widely used dock type in coastal and inland oil and gas chemical ports and docks. Among them, the pipelines of the oil and gas chemical dock are arranged on the fixed approach bridge, valve room platform, movable steel approach bridge and pontoon. The movable steel approach bridge is connected to the valve room platform and pontoon with a hose. As the water level changes, the movable steel approach bridge moves on the pontoon deck, the bracket and the valve room platform, and the hose connecting the movable steel approach bridge pipeline to the pontoon is stretched accordingly, and the hose connecting the movable steel approach bridge to the valve room platform also moves accordingly. This part usually has a large number of pipelines, and the pipe racks are arranged in multiple layers. The hoses are staggered and closely arranged, and are directly placed on the deck surface, the end face of the steel approach bridge or the valve room platform surface.

[0003] A search of CN213452129U disclosed a hose lifting device for an oil and gas chemical terminal. The pipe rack is raised and lowered as a whole by a winch to meet the hose lifting height at different water levels, effectively solving safety issues such as pipeline damage and static electricity generated by friction caused by the movement of the hose on the valve room platform, movable steel approach bridge and pontoon.

[0004] The lifting device can adjust the height of the hose up and down to prevent the hose from being damaged during movement. However, the lifting device directly places the hose on the hose roller during placement, and does not limit the hose. In this way, the hose will fall off during use, which will still cause damage to the hose. Utility Model Content
