Cantilever-type slidable anti-collision connection device for ship berthing platform

Abstract

A cantilever-type slidable anti-collision connection device for a ship berthing platform is characterized in that a winch is fixed over the platform, a bidirectional shaft is fixed to the side of the platform, one end of a lattice boom is connected with the bidirectional shaft, and a manipulator is disposed at the other end of the lattice boom, the lattice boom is formed by connecting hydraulic dampers in order, the manipulator is formed by connecting two semicircular rings through a hinge, a steel ball with a retainer is arranged within the manipulator, a rubber cushion layer is arranged between the manipulator and the steel ball, and another rubber cushion layer is fixed between the side of the platform and the bidirectional shaft. The ship connection end of the cantilever-type slidable anti-collision connection device is capable of sliding up and down and rotating, so that damage of connections caused by a ship floating in sea currents and waves during berthing can be prevented. The cantilever-type slidable anti-collision connection device is used a safety distance away from the ship, so that no collision between the ship and the platform occurs. The lattice boom is capable of extending and retracting, an operation range of the ship can be guaranteed to the maximum extent; a hydraulic damping system is mounted in the lattice boom, and the service life of the cantilever-type slidable anti-collision connection device is prolonged. The cantilever-type slidable anti-collision connection device is simple in structure, convenient to use and safe and reliable.

Description

technical field [0001] The invention belongs to an anti-collision device used for berthing ships on an ocean platform.

When the ship is connected to the offshore platform, the impact of the ship on the platform and the damage of the connecting components often occur, and even part or most of the platform is damaged

[0003] At present, there is no anti-collision device design specifically for the structural connection between ships and offshore platforms. Other similar anti-collision devices are mostly used as bridge piers or land structures for anti-collision use. Such mechanical equipment or structure anti-collision patents are generally used to prevent collisions, The main purpose is to reduce the impact energy, and the influence of factors such as height difference, distance, and relative rotation between anti-collision objects is rarely considered. However, the ocean environment where the offshore platform is located is very complex, and environmental influences such as waves, wind, currents, and tidal fluctuations It will definitely cause great changes in the height difference, distance, relative rotation angle, etc. between the connection point of the ship and the offshore platform

The traditional way of connecting a platform to a ship is to hoist a truss girder directly between the ship and the offshore platform. There is no special treatment for the connection part of this connection method. With the change of wind, waves and currents, the position of the offshore platform is not fixed. However, the ship connected to it will rotate, float up and down or change the distance greatly, which may cause mutual collision between the offshore platform and the ship or damage or separation of the connecting parts at any time. The detachment of components will not only cause damage to the connecting components, resulting in the inability to continue the oil transportation work, but also cause partial damage or even collapse of the offshore platform, which will greatly affect the safety of the offshore platform and ships

Therefore, the general energy transmission work can only be carried out in a particularly stable and good state in the sea area. The limitation of the use of the device has caused the limitation of the oil transportation work. Therefore, it is urgent to design a multi-directional adjustable anti-collision that can work around the clock connecting device
