Description

Technical Field

[0001] The invention belongs to the field of marine steel structure engineering, and in particular relates to a conductor rack hoisting lock buckle personnel lowering system and method. Background Art

[0002] The offshore lifting of the offshore platform jacket can be divided into two types: vertical lifting and horizontal lifting. The vertical lifting process requires the rope operator to board the lock platform to perform the hook operation. After the operation is completed, the personnel need to evacuate the lock platform. Usually, the lock hook of the crane ship is used to lift the personnel to the barge deck for evacuation. For jackets over 50 meters high, if the lock hook is used, there is a risk of pulling down the jacket. The patent of this invention designs a personnel lowering system that can lower the rope operator from the lock platform to the deck surface.

[0003] Therefore, it is urgent to design a system and method for lowering personnel for hanging locks and buckles of pipe rack hoisting to solve the above-mentioned problems. Summary of the invention

[0004] The object of the present invention is to provide a conductor rack hoisting lock buckle personnel lowering system and method, which has the advantage of being able to lower the rope operator to the barge deck for safe evacuation, and solves the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the catheter rack hoisting lock buckle personnel lowering system and method of the present invention is as follows: A conductor frame hoisting lock buckle personnel lowering system comprises a conductor frame lock platform arranged on a barge deck, the conductor frame lock platform is fixedly connected to a power control unit, a submersible cage is connected to the power control unit, the submersible cage is used for pulling rope personnel and objects, and the submersible cage is driven to move by the power control unit.

[0006] Furthermore, the power control unit includes a fixed end and an output end. The fixed end of the power control unit is fixedly connected to the catheter rack lock platform, and the output end of the power control unit is connected to the submersible cage. The submersible cage is driven to move through the output end of the power control unit.

[0007] Furthermore, the output end of the power control unit is connected to a crane part, and the crane part is connected to the submersible cage.

[0008] Furthermore, the submersible cage is linked to the crane unit via a lifting chain.

[0009] Furthermore, it also includes a remote controller, which is electrically connected to the power control unit, and controls the movement of the output end of the power control unit through the remote controller.

[0010] A method for lowering personnel for lifting a catheter rack with a lock hook, using a system for lowering personnel for lifting a catheter rack with a lock hook, comprises the following steps: S1. The rope operator enters the diving cage located on the catheter rack lock platform; S2, the power control unit then drives the diving cage to slide along the top surface of the jacket lock platform toward the outside of the jacket lock platform; S3. After the submersible cage moves out of the locking platform of the conductor rack, the power control unit drives the submersible cage to slide toward the deck of the barge; S4, until the diving cage lands on the barge deck, and then the rope operator evacuates from the diving cage.

[0011] Further, in S1, the rope operator enters the diving cage after completing the hooking operation.

[0012] Further, in S1, the submersible cage is linked to the crane part of the power control unit via a lifting chain.

[0013] Furthermore, in S2 and S3, the power control unit is controlled by a remote controller.

[0014] Further, the remote controller is operated by a deck crew located on the deck of the barge or by a cable operator.

[0015] The present invention has the following advantages: installing a power control unit on the conductor rack lock platform is equivalent to independently installing the lower system on the conductor rack lock platform, avoiding the effect of using the lock hook to lower and cause safety hazards. At the same time, the barge deck personnel can remotely control the submersible cage to lower the ropeman to the barge deck for evacuation, or the ropeman can control the submersible cage himself, and the ropeman evacuates after the submersible cage is lowered to the barge deck.
