Technical Field

[0001] The invention belongs to the technical field of offshore oil engineering, and in particular relates to a shallow water Christmas tree hydraulic control valve operating tool. Background Art

[0002] In the installation project of the Christmas tree underwater production system, a special hydraulic tool is needed to lock the Christmas tree valve. In deep water environment, ROV is usually used for operation. However, due to the low visibility underwater in Bohai Sea, ROV cannot be used, and divers are required to operate the hydraulic tool in the water.

[0003] However, the underwater operation of the divers highlighted two problems: First, the hydraulic tool has no rotation stop plate, and the diver cannot stop it in time after rotating it to the right position, which may cause the diver to over-rotate and fall off during underwater operation. Second, the tool needs to be rotated 45 degrees to be completely locked. The hydraulic tool lacks a tooling that rotates the float synchronously during the rotation locking process. There is a risk that the buoyancy of the float will pull the tool to rotate 45 degrees in the opposite direction, and unlocking the tool also poses a safety risk to the diver.

[0004] Therefore, it is urgent to design a shallow water oil production tree hydraulic control valve operating tooling to solve the above-mentioned problem of locking the oil production tree valve by the hydraulic tool. Summary of the invention

[0005] In order to solve the problem that the hydraulic tool mentioned in the background technology has no rotation stop plate, the diver cannot stop in time after rotating it to the right position, there is a risk of over-rotation and falling off when the diver operates underwater, and it can only be completely locked after rotating 45 degrees. The hydraulic tool lacks a tooling for synchronous rotation of the float during the rotation locking process. There is a technical problem that the buoyancy of the float pulls the tool to rotate 45 degrees in the opposite direction, and the unlocking tool also poses a safety risk to the diver. A shallow water oil tree hydraulic control valve operating tool is provided to solve the problem of hydraulic tools locking the oil tree valve.

[0006] To achieve the above-mentioned purpose, the specific technical scheme of the shallow water Christmas tree hydraulic control valve operating tooling of the present invention is as follows: A shallow water Christmas tree hydraulic control valve operating tool comprises a fixed ring and a sliding ring, wherein the sliding ring is connected to the fixed ring, the fixed ring is clamped on the groove of the hydraulic tool, the fixed ring is provided with a bolt hole, a fixed base is hinged on the bolt hole of the fixed ring, the fixed base is connected to the hydraulic tool, a floating ball is connected to the sliding ring, the hydraulic tool is inserted into the Christmas tree valve, and the hydraulic tool is driven to rotate 45 degrees by the sliding ring to lock the hydraulic tool with the Christmas tree valve.

[0007] Furthermore, the sliding lifting ring is hinged at the opening of the fixed circular ring.

[0008] Furthermore, the openings of the fixed ring are respectively connected to vertical plates, and the two ends of the sliding ring are respectively connected to the two vertical plates.

[0009] Furthermore, first screw holes are symmetrically provided on the two vertical plates, and a fixed base is connected inside the first screw holes.

[0010] Furthermore, a second screw hole is provided on the fixed base, and a bolt passes through the first screw hole of the vertical plate and the second screw hole of the fixed base, so that the fixed base is hinged on the fixed ring.

[0011] Furthermore, the fixed base is fixedly connected to the upper connecting plate of the hydraulic tool at one side away from the second screw hole.

[0012] Furthermore, a notch is provided on one side of the second screw hole of the fixed base so that the structure on the hydraulic tool can pass through the notch.

[0013] Furthermore, the sliding lifting ring is connected to the floating ball via a shackle.

[0014] Furthermore, the fixed ring is inserted into the groove of the hydraulic tool, and the sliding lifting ring is located above the hydraulic tool.

[0015] Furthermore, the upper connecting plate of the hydraulic tool is connected to the fixed base so that the angle between the fixed base and the fixed ring is 90 degrees.

[0016] The shallow water Christmas tree hydraulic control valve operating tool of the present invention has the following advantages: By setting a fixed ring on the groove of the hydraulic tool, the fixed ring is hinged with the fixed base, and the fixed base is connected to the hydraulic tool, the sliding ring connected to the fixed ring is rotated, the sliding ring is rotated 45 degrees, and the floating ball connected to the sliding ring is synchronously rotated 45 degrees and always kept at the top of the tool. After the hydraulic tool is rotated into place, it will not automatically reset due to the influence of the floating ball.
