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 crane ship balance system and a working method thereof. The crane ship balance system comprises a ship body, balance water grooves, tuning balance water tanks, lift fans, self-balance cranes and a PLC control system; the balance water grooves are formed in ship rails of the two sides of the ship body, the tuning balance water tanks are arranged at the head part and the tail part of the interior of the ship body and comprise main water tank bodies and subsidiary water tank bodies, and the lift fans are arranged on decks around the ship body respectively; two crane tracks are arranged on the decks and provided with the self-balance cranes, and balancing arms of the self-balance cranes are provided with fixed weight balance blocks and variable weight balance water tank devices. According to the crane ship balance system and the working method thereof, gravity and buoyancy of the balance water grooves, the gravity of the tuning balance water tanks and balance moment which is provided by the lift fans for the ship body are utilized, the cranes can automatically adjust the balance force when conduct craning for carrying goods, the whole system is connected to thePLC control system to be automatically controlled, and the requirement for machining and manufacturing novel ships is met.

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...
