Blowout preventer transportation and installation device for oil drilling platform

The utility model belongs to the field of oil exploitation machines, and particularly relates to a blowout preventer transportation and installation device for an oil drilling platform. Full hydraulic control and semi-automation are achieved through the blowout preventer transportation and installation device. The whole installation device has five spatial freedom degrees so that a blowout preventer can be longitudinally moved, turned over, lifted, rotated and transversely moved in the installation operation and the functions of alignment connection of flange threaded holes, detachment, repair and the like can be achieved in the blowout preventer pairing process. All motions are completed through a hydraulic operation device fixed to a trolley sledge base by an operator, the whole process is coherent and simple, the installation procedure of the blowout preventer is effectively simplified, the labor intensity is relieved to a large extent, and the work efficiency and the safety are greatly improved.
