[0003] Previous blowout preventer (BOP) guiding devices did not have a structure to help the operator to observe from above in real time during operation. Multiple additional personnel were required to assist in observation and communicate with the operator in real time. This made BOP alignment time-consuming, labor-intensive, and costly. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a guiding device for drilling blowout preventers. During operation, it has a structure that helps the operator to make real-time overhead observations, saving time and effort when aligning the blowout preventer and helping to reduce operating costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is a guiding device for drilling blowout preventers, including a top plate, a triangular top block, a support frame, a fixed platform, a hydraulic cylinder, a drive rod, an extension rod, and a moving platform. The top of the fixed platform is fixed with hydraulic cylinders near the corners by bolts. The power output end of the hydraulic cylinder is connected to the drive rod. The lower end of the fixed platform is provided with a moving platform, and the bottom of the moving platform is provided with a blowout preventer mounting hole.

[0006] Connecting blocks are provided on both sides of the bottom end of the top plate. The connecting blocks are connected to the support frame by the first bolt. A side plate is provided at one end of the top plate. Mounting holes are provided through the side plate near the corner. A camera is mounted on the bottom of the fixed platform near the center by a fixed seat. A slot is provided through the top of the moving platform at the position corresponding to the camera. A U-shaped block is fixed to the bottom of the drive rod by the second bolt. A connecting plate is connected to the bottom of the U-shaped block by an extension rod. The moving platform is fixed to the bottom of the connecting plate by bolts.

[0007] By adopting the above technical solution, personnel can easily observe the footage captured by the camera when aligning the blowout preventer with the wellhead. The system also has a structure that helps personnel to make real-time overhead observations during operation, saving time and effort when aligning the blowout preventer and reducing operating costs.

[0008] Specifically, a triangular top block is fixed to the top of the top plate by bolts, and a hanging block is connected to the top of the triangular top block. A connecting groove is opened on the top of the hanging block near both sides.

[0009] By adopting the above technical solution, a pin is inserted into the connecting hole, and a lifting hole is provided on the pin. The lifting hole is connected and fixed to the main structure of the external lifting mechanism by a steel wire rope, thereby improving the stability of this guide device when it is fixed.

[0010] Specifically, a connecting hole is provided through one side of the triangular apex block.

[0011] Specifically, the top two sides of the support frame are fixed with a reinforcing frame by a third bolt at the corner of the top plate.

[0012] Specifically, the mobile station is equipped with chamfers near the corners.

[0013] By adopting the above technical solution, and by setting chamfers at the corners of the mobile platform, the sharp edges of the mobile platform can be reduced, thereby reducing the risk of accidental collisions during movement.
