Description

Marine crane

The present invention relates to a marine crane.

In general, a crane (crane) is a mechanical device for lifting the load (운반 物) to transport up and down, left and right, back and forth. A crane is also called a crane, and is a mechanical device that lifts a heavy object and moves it to a desired position.

Cranes are variously applied according to the purpose of use and movement method, but the overhead crane is mainly used to transport heavy materials in facilities such as factories or warehouses.

This overhead crane lays rails along the walls facing each other and spans a beam running at right angles to the rails. A trolley with hoisting and traversing devices is attached to this beam to lower the hooks from the trolley to lift the heavy goods. With proper control of the beam's travel and transverse movement on it, the cargo can be transported anywhere in the building. In addition, when the heavy material to be transported is loaded without any form, such as waste, coal, gravel ore, a basket-shaped bucket may be installed at a hook position to transport the heavy material in the bucket.

Conventional crane is installed on the ground, the trolley is moved by the user's operation and moved to the position of the heavy material transported in a state of lowering the bucket using a hoisting device with a wire or chain installed to store the heavy object inside the bucket Can be lifted to the top and transported to the desired position.

However, when the above-mentioned crane is installed inside the ship with a heavy flow, there is a problem that the heavy material is hardly stored in the bucket as the bucket connected to the hoisting device in which the wire or the chain is installed is shaken by the flow. In other words, the bucket of the shape of the wire or chain hanging on the chain has a problem that it is difficult to accommodate the heavy object in the bucket because the movement is severe as the movement along with the flow of the vessel.

In addition, if the flow meets high waves during the ship operation, or the climate is bad, such as a typhoon, the flow of the buried bucket can be damaged while crashing inside the vessel, there was a problem that the inner wall of the crashing vessel is also damaged.

In addition, as the crane fails to maintain a fixed state, a continuous load acts on the wire or chain connected to the bucket as the flow of the vessel moves, and the service life is reduced, and when the load acts more than the strength of the wire or the chain. There was a problem that the bucket is released to the outside while being broken to collide with the ship, or personnel accidents hit the worker.

In addition, the ordinary ceiling crane is installed in the interior of the space divided by the wall to the rail facing the wall facing each other and transported from the position loaded in the space to the desired position, and transferred to another space separated by the wall To this end, as other transport devices such as a vehicle or a rail running on a rail must be further provided, the facility is expanded and the facility cost is increased.

In particular, a ship is divided into a plurality of compartments to carry out cargoes stored in each compartment to another compartment, or, when a power generation facility is installed inside the vessel, power generated in the compartment is installed in another compartment. When transporting to be supplied to the facility there was a problem that is difficult to transport with a conventional crane for transporting cargo in a space.

The problem to be solved of the present invention is to be transported while moving in a fixed state of the crane, even if installed inside the vessel with a heavy flow, the flow of the bucket is minimized, and can be transported while moving between the divided compartments of the ship The present invention relates to a marine crane with improved transportation performance.
