The front end of the hydraulic cylinder's push rod is hinged to the first or second tilting table; one end of the first or second tilting table is hinged to the central support of the frame. When the hydraulic cylinder's push rod is in place, one end of the first or second tilting table tilts up. When the plane of the first or second tilting table is perpendicular to the horizontal plane, the cylinder of the self-locking mechanism drives the self-locking plate to block the sliding guide rod of the self-locking mechanism, forming a fixed 90° angle between the planes of the first and second tilting tables; ensuring that the 90° angle remains unchanged when the first or second tilting table is tilted in the opposite direction.

When the turnover flat plate is turned upward, the sliding guide rod is retracted downward; when the upper end of the guide rod is retracted below the self-locking flat plate, the self-locking flat plate is extended, and the sliding guide rod cannot be returned, and the 90-degree angle between the first turnover table and the second turnover table is unchanged. When the first turnover table is not turned to the vertical position, the end of the sliding guide rod extends above the self-locking baffle; when the first turnover table is turned to the vertical position, the end of the sliding guide rod is retracted below the self-locking baffle. The self-locking baffle is extended under the pushing of the shaft of the self-locking oil cylinder, and blocks the end of the automatic sliding guide rod, so that the end cannot be extended. The 90-degree angle between the first turnover table and the second turnover table is maintained.

[0047] The hydraulic station 11 is installed at one end of the rack 7, and an electric control box is arranged close to the hydraulic station 11; the electric control box is isolated from the hydraulic cylinder lifting mechanism, so that safety and independence are ensured. The turnover flat plate lifting cylinder outer shell is slidably connected with the cylinder rod lower hinge, and the cylinder rod lower hinge is slidably connected with the equipment rack. The cylinder lifting rod is slidably connected with the first turnover table or the second turnover table by a cylinder upper hinge. The first turnover table and the second turnover table are slidably connected with the equipment rack by a turnover flat plate center hinge. The first turnover table and the second turnover table are centered on the turnover flat plate center hinge; the other end is lifted, and the first turnover table and the second turnover table can form a 90-degree angle or can be completely flat to form a 180-degree plane; the placing and maintenance operation of the workpiece needing to be turned over are greatly facilitated.

[0048] In summary, the full-automatic blowout preventer turnover device can ensure that the angle between the two turnover tables is unchanged, and facilitates the placing and maintenance operation of the workpiece needing to be turned over.
