Multipurpose ship berthing device

Abstract

The invention discloses a multipurpose ship berthing device. The multipurpose ship berthing device is characterized in that the multipurpose ship berthing device comprises one or more double-acting single-piston oil cylinders arranged in a ship; an electromagnet is fixed at the outer end of each piston rod; a hydraulic system controls extension of the piston rods in the double-acting single-piston oil cylinders and controls power-on/power-off of the electromagnets. Secondary depression slow pulling devices are mounted at the front ends of the piston rods respectively. When a large ship is docked, each piston rod extends outwards under the action of the oil cylinders, and the ship gradually approaches the shore side of a wharf; the electromagnets are powered on to generate powerful magnetic force, the front ends of the electromagnets are enabled to be tightly adhered to the shore side of the wharf, and the ship is slowly docked toward the wharf under the action of the multiple piston rods to finally approach the wharf smoothly, so that the impact force of the ship to the wharf during docking is greatly reduced, and the safety of the wharf is guaranteed. The device is applicable to mutual berthing among offshore ships, and effective transverse safety mooring between two ships is realized.

Description

technical field [0001] The invention relates to the field of ship equipment, in particular to a multi-purpose ship berthing device technology. Background technique [0002] At present, in order to alleviate the contradiction between the insufficient handling capacity of the wharf design and the increasing production demand, it is often necessary to strengthen the structural transformation of the old wharf and improve the adaptability of the old wharf to new ship types; in addition, many port projects are currently under construction. , the impact force generated by the ship berthing, the mooring force generated by the offshore wind after the ship berthed, and the ship squeeze force generated by the onshore wind are three common dock dynamic loads. This lateral force has a particularly significant impact on high-piled wharves and deep-water open wharfs, and must be considered in wharf structural design and safe operation. [0003] In order to prevent the ship from collidin...

Problems solved by technology

But there are many defects in utilizing waste tires as the anti-collision decompression device: 1, when the ship is docked, because the ships are still in motion, and the waste tires are fixed, only when the ships are close to the shore, the waste tires just play a role. Protective effect, the ship has a great impact on the tires, and there will be greater friction between the waste tires and the ship, which will still cause damage to the ship's surface; The effect is limited, especially under the action of strong transverse wind, when the ship docks too fast, the existing fixed protection device often cannot effectively protect the hull and the pile platform in front; Into the water causing water pollution

The above-mentioned berthing method has the following disadvantages: 1. It requires multiple people to operate at the same time, which is time-consuming and labor-intensive, and there is a certain risk; 2. The position of the ship's berthing is not very accurate, and friction and collision between the hull and the dock often occur
