[0039] This utility model discloses a device for disassembling and assembling a blowout preventer gate.

[0046] The first guide plate 52 and the first cylinder top block 54 are based on the support connection mechanism 2. The first end of the first push-pull cylinder 51 is disposed on the first cylinder top block 54. The second end of the first push-pull cylinder 51 is connected to the first sliding plate 53.

[0049] In addition, the blowout preventer gate disassembly device may further include a hydraulic oil tank, hydraulic lines and a hydraulic control valve 8; the hydraulic oil tank is connected to the lifting cylinder and the push-pull cylinder respectively through the hydraulic lines and the hydraulic control valve.
[0050] In one application scenario of this utility model, the blowout preventer gate disassembly and assembly device includes: a hoisting mechanism, a hydraulic mechanism, a clamping mechanism, an ejection mechanism, and a magnetic adsorption mechanism.
[0051] The lifting mechanism is used to connect with the power-assisted manipulator or other movable lifting devices. The lifting mechanism is equipped with lifting fixing holes, which can realize fixed docking with other devices and can move in the horizontal and vertical directions, thereby enabling the removal and installation of the blowout preventer gate 10 from the blowout preventer body 9.
[0052] The hydraulic mechanism includes a lifting hydraulic cylinder and a push-pull cylinder, hydraulic lines, and hydraulic control valves. During gate clamping, the lifting hydraulic cylinder provides hydraulic power to the clamping mechanism, thereby clamping the gate plate. The hydraulic lines and hydraulic control valves switch the gripping and releasing actions of the lifting cylinder when clamping the gate plate; for the ejection mechanism, they switch the ejection and pulling actions of the push-pull cylinder.
[0053] The clamping mechanism includes a connecting rod, a clamping chuck, and a clamping plate. When the lifting cylinder is working, the vertical motion of the lifting cylinder can be converted into the rotational motion of the clamping jaws through the geometric movement of the connecting rod and the clamping plate in space. This allows the clamping jaws to convert the ejection pressure of the lifting cylinder into a clamping and lifting force on the gate.
[0054] The ejection mechanism includes a guide plate, a sliding plate, and a hydraulic cylinder push block. The power for the ejection mechanism is provided by an ejection push-pull hydraulic cylinder. When removing the gate from the blowout preventer, due to prolonged sludge blockage, considerable force is required to remove the gate from the blowout preventer's clips. The push-pull hydraulic cylinder provides power to overcome the sludge and other blockages during disassembly and installation, facilitating the removal and installation of the gate.
[0055] The magnetic adsorption mechanism consists of permanent magnets and a magnetic control mechanism. The specifications of the permanent magnets can be customized to meet different requirements, such as 600kg or 1t. Its main function is to enable the gate plate to be adsorbed after being clamped by the chuck, providing horizontal positioning and lifting assistance, thus achieving a smooth and safe removal and installation of the gate plate from the blowout preventer. The permanent magnet controller uses a motor and belt to control the opening and closing of the permanent magnet's magnetic force.
[0056] In one application scenario of this utility model, the process of disassembling and assembling the blowout preventer gate using the blowout preventer gate disassembly and assembly device of this utility model includes:
[0057] After the blowout preventer's side door is opened, the gate plate is exposed. This gate plate removal and assembly device, using lifting equipment such as a power-assisted manipulator, moves the gate plate to a suitable position above it for alignment. The clamping jaw switch is activated, and the hydraulic valve group controls the lifting cylinder to lift it. Through the linkage mechanism and clamping mechanism, the jaws grip the gate plate. Once the gripping action is in place and complete, the permanent magnet controller switch is activated, and the magnet attracts the gate plate surface. The push-pull cylinder switch is activated, enabling the push-pull cylinder to advance. After the cylinder top block reaches the blowout preventer body, the reaction force causes the clamping mechanism to move in the opposite direction, overcoming the frictional resistance between the gate plate and the blowout preventer, and separating the gate plate from the blowout preventer. The gate plate is then placed in the designated position using the lifting equipment such as the power-assisted manipulator. The magnet controller switch is deactivated, removing the attraction force. The hydraulic valve group switch is switched, and the lifting cylinder pushes down, releasing the clamps. This completes the entire process of removing the gate plate from the blowout preventer.
[0058] Conversely, the installation process for the gate valve is similar. Because both the blowout preventer and the gate valve are cleaned during installation, there is no installation resistance. Simply clamp the gate valve and use lifting tools such as a robotic arm to move it to the appropriate position to complete the installation.
[0059] In summary, the blowout preventer gate disassembly and assembly device proposed in this utility model can improve the automation level of blowout preventer gate disassembly and assembly, increase work efficiency, and reduce labor costs.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
