The technical realization elements of the fully automatic gangway device of the wave-adaptive offshore platform

4. The technical problem to be solved by this utility model is to provide a wave-adaptive automatic gangway device for ocean platforms, which has a simple structure and adopts a telescopic ladder in the space between the fixed ladder and the ship’s outboard, and the drive system is located on the ocean platform. On the deck, the noose wound on the winch is connected to the telescopic ladder. The laser ranging system is located at the bottom of the telescopic ladder. One end of the security device is connected to the deck of the offshore platform, and the other end is connected to the telescopic ladder. The ship is driven to the side of the offshore platform by laser After the ranging system is detected, the plc control system controls the telescopic ladder to fluctuate with the ship according to the preset height, and always keeps the height of the operator stepping on the folding pedal unchanged. When the operator climbs, it is connected to the security device to avoid the collision of the gangway with the ship. And when the operator collides with the ship, it can prevent the operator from falling in a fast state, which is safe and reliable, low cost, simple and convenient to operate.

5. In order to solve the above technical problems, the technical solution adopted by this utility model is: a wave-adaptive marine platform full-automatic gangway device, which includes a fixed ladder, a telescopic ladder, a driving system, a laser ranging system and a security device; The driving system is located at the upper end of the fixed ladder, the telescopic ladder is vertically parallel to the fixed ladder, the driving system is connected with the telescopic ladder, the laser ranging system is located at the lower end of the telescopic ladder and connected with it, and the security device is suspended on the fixed ladder and the side of the telescopic ladder; The driving system automatically controls the telescopic ladder to adjust the height vertically along the fixed ladder according to the height feedback from the laser ranging system.

6. The fixed ladder is a straight ladder, a plurality of mutually symmetrical fixed supports are arranged on both sides, and a limit plate is arranged at the middle and lower part of the straight ladder.

7. The telescopic ladder is a straight ladder, with a limit support on the back side of the upper end, and a lifting ear plate in the middle, which is located at the bottom

Folding pedals are arranged in the lower part of the folding pedals, and a safety ear plate is arranged on the lower side of the folding pedals to connect with the straight ladder.

8. The limit plate of the fixed ladder and the limit support of the telescopic ladder cooperate with the limit.

9. The driving system includes a noose wound on a winch, a fixed pulley and a noose roll in cooperation, and the noose is connected with the lifting lugs of the telescopic ladder.

10. The laser ranging system is connected with a plc control system, and the plc control system controls the driving system to adjust the height of the telescopic ladder according to the height measured by the laser ranging system.

11. The security device includes lap buckles respectively connected to the two ends of the safety rope, one end of the lap buckle is connected to the ear base, and the other end of the lap buckle is connected to the safety ear plate of the telescopic ladder.

12. An anti-dropping device is arranged on the safety rope, and the buckle of the anti-dropping device is connected with the safety rope.

13. A wave self-adaptive marine platform full-automatic gangway device, which includes a fixed ladder, a telescopic ladder, a drive system, a laser ranging system and a security device; the drive system is located on the upper side of the fixed ladder, and the telescopic ladder and the fixed ladder are vertical Parallel, the drive system is connected to the telescopic ladder, the laser distance measuring system is located at the lower end of the telescopic ladder, and the security device hangs on one side of the fixed ladder and the telescopic ladder; the drive system automatically controls the telescopic ladder to be erected along the fixed ladder according to the elevation feedback from the laser distance measuring system Adjust the height straight up and down. The structure is simple. A telescopic ladder is set in the space between the fixed ladder and the ship’s outboard. The drive system is located on the deck of the offshore platform. The noose wound on the winch is connected to the telescopic ladder. The laser ranging system is located at the bottom of the telescopic ladder. One end of the device is connected to the deck of the offshore platform, and the other end is connected to the telescopic ladder. After the ship travels to the side of the offshore platform and is detected by the laser ranging system, the plc control system controls the telescopic ladder to rise and fall with the fluctuation of the ship according to the preset height. The height at which the operator steps into the folding pedal remains unchanged, and the operator is connected to the security device when climbing to avoid the collision between the gangway and the ship and the collision between the operator and the ship, and avoid the operator from falling in a rapid state. It is safe, reliable, low-cost, and easy to operate. convenient.

14. In a preferred solution, the fixed ladder is a straight ladder, a plurality of mutually symmetrical fixed supports are arranged on both sides, and a limit plate is arranged at the middle and lower part of the straight ladder. The structure is simple. During installation, the fixed support is connected and fixed with the outboard plate of the hull of the offshore platform, and a space for the telescopic ladder is reserved between the outboard plate and the fixed ladder, so that the telescopic ladder can move vertically in the space.
