Problems solved by technology

The usual lifting and feeding transport ships are equipped with rail cranes on both sides of the ship for hoisting and handling cargo, but in the process of hoisting cargo, due to the instability of the ship, it is easy to cause the center of gravity of the crane to be unbalanced, resulting in tilting and overturning, thereby reducing The service life of the crane; at the same time, when lifting heavy objects in large quantities, the center of gravity of the ship is unstable, which may easily cause the ship to roll over, and the phenomenon of cargo scattering caused by the swaying of the ship during transportation and navigation

Embodiment 1

[0034] A balancing system for lifting ships, including a hull 1, and also includes a balancing water tank 2, a tuning and balancing water tank 3, a lift fan 4, a self-balancing crane 5, and a PLC control system 6; the balancing water tank 2 is provided with two groups, respectively On the sides 1.2 of the hull 1, the balance tank 2 includes a tank body 2.1 and a hydraulic telescopic arm 2.2. The tank body 2.1 is a U-shaped boat structure with an open top, and the bottom of the tank body 2.1 is hinged on the hydraulic telescopic arm 2.2. The extension end, the side of the tank body 2.1 is hinged to the extension end of the flip hydraulic cylinder 2.4, the bottom end of the flip hydraulic cylinder 2.4 is hinged to the hydraulic telescopic arm 2.2, and the head end of the hydraulic telescopic arm 2.2 is hinged to the side of the ship 1.2 , the hydraulic telescopic arm 2.2 is provided with an extension hydraulic cylinder 2.3, the extension end of the extension hydraulic cylinder 2....

Embodiment 2

[0041] The structure and principle of this embodiment 2 are basically the same as that of embodiment 1. The difference is that the rotary table 5.6 is provided with a crane rotation angle sensor 5.11. The PLC control system is convenient for the control system to quickly calculate the position of the center of gravity and adjust the balance of the hull.

Embodiment 3

[0043] The structure and principle of this embodiment 3 are basically the same as that of embodiment 1. The difference is that the balance arm 5.3 is provided with a fixed counterweight 5.7, and the counterweight can be used to balance the counterweight when the crane is empty, so as to avoid the crane being empty. Rollover occurs due to the shaking of the hull during loading, and the balance of gravity can also be used when lifting cargo.

Abstract

The invention provides a balancing system for a lifting ship and a working method thereof, comprising a hull, a balancing water tank, a tuning and balancing water tank, a lift fan, a self-balancing crane and a PLC control system; the balancing water tanks are arranged on the sides of the hull, The tuning and balancing water tank is arranged at the bow and tail of the hull, the tuning and balancing water tank includes a main water tank and an auxiliary water tank, and the lift fans are respectively arranged on the decks around the hull, and two sets of lifting fans are arranged on the decks. A self-balancing crane is arranged on the lifting rail, and a fixed counterweight and a variable counterweight water tank device are arranged on the balance arm of the self-balancing crane. The invention utilizes the gravity and buoyancy of the balance water tank, the gravity of the tuning balance water tank and the lift fan to provide the balance moment of the hull, the crane can automatically adjust the balance force when lifting and transporting goods, and the whole system is connected to the PLC control system to realize automatic control , in line with new ship manufacturing requirements.

Description

technical field [0001] The invention belongs to the technical field of lifting ships, and relates to a balancing system and a working method thereof. Background technique [0002] At present, there are medium and large lifting and feeding transport ships among ships, which can lift the goods and transport them to large oil tankers docked in the deep sea. The ships can be used in imperfect ports. The usual lifting and feeding transport ships are equipped with rail cranes on both sides of the ship for hoisting and handling cargo, but in the process of hoisting cargo, due to the instability of the ship, it is easy to cause the center of gravity of the crane to be unbalanced, resulting in tilting and overturning, thereby reducing The service life of the crane; at the same time, when lifting heavy objects in large quantities, the center of gravity of the ship is unstable, which may easily cause the ship to roll over, and the ship will sway during transportation and navigation, ca...
