Abstract
The present invention relates to a marine crane capable of moving a boom. Specifically, according to an embodiment of the present invention, there is provided a boom comprising: a boom to which a lifting rope for lifting a heavy object is connected; A bogie portion provided on an upper surface of the barge and movably supporting the boom on the barge; And a connecting part connecting the boom to the boom.
Description
The present invention relates to a marine crane capable of moving a boom.
In general, the shipbuilding industry, which consists of designing, building and delivering, starting with the order of the ship, determines the survival and success of the industry. An important factor in determining such profitability is productivity in the process of ship construction, and all shipbuilding industries compete for productivity improvement.
In order to improve the drying capability of vessels, various shipbuilding facilities are required, including large scale shipyards, efficient planned production plans, and marine cranes to support new drying methods.
Conventional marine cranes are very large to handle hundreds to thousands of tons of heavy goods at the shipyard. In addition, the marine crane lifts heavy objects by using seawater having a higher specific gravity than ordinary water as a supporting base. Most of the marine crane is placed on an inclined hull of a general barge and is equipped with a crane boom to be manufactured in an undulation type have.
The principle of lifting a heavy object using such a floating crane is such that the free end of the lifting rope extending downward from the upper portion of the boom is fixed to the heavy object and the lifting rope is lifted from the upper portion of the boom to float the heavy object . In addition, the boom is stably held by the wire rope having one end connected to the fixed frame disposed on the deck of the barge and the other end connected to the upper portion of the boom.
However, in the conventional marine cranes, the position of the boom is fixed. Therefore, in order to transport the heavy object to a relatively long distance, the heavy object has to be lifted to the air and the barge has to be drawn to the target point. As a result, there is a problem that the fatigue breakdown can proceed due to the load acting on the structure of the boom, and the lifetime of the boom can be shortened and the structural stability can be hindered.
Further, there is a problem that maintenance and repair of the boom is not easy as the position of the boom is fixed.
The embodiments of the present invention have been made to solve the problems of the prior art, and it is possible to mount a heavy object on a deck of a barge when a heavy object is transported at a long distance, thereby securing the structural stability without significantly shortening the life of the boom. And it is an object of the present invention to provide a marine crane capable of easily maintaining and repairing a boom.
According to an aspect of the present invention, there is provided a boom comprising: a boom to which a lifting rope for lifting a heavy object is connected; A bogie portion provided on an upper surface of the barge and movably supporting the boom on the barge; And a connection part connecting the boom to the boom, wherein the boom is movable.
Further, it is possible to provide a floating crane capable of moving the boom further including a guide portion for guiding the movement of the bogie portion.
Further, the braking unit may include a wheel provided to be rotatably driven, and the rotation driving of the wheel may be provided with a floating crane capable of moving the boom guided by the guide unit.
In addition, a guide groove for receiving the wheel is formed on the upper surface of the guide portion. The guide portion is provided on a bottom surface of the guide groove, and the movement of the boom including the rail, which is in contact with the wheel, Possible marine cranes may be provided.
Further, the bogie portion may include: a support plate connected to a lower surface of the connection portion; A wheel provided rotatably driveable; And a driving body connecting the wheel to the support plate.
The driving body may further include: a driving device for transmitting a driving force to the wheel; And a braking device for braking the wheel, can be provided.
Further, a plurality of the wheels may be provided, at least a part of the plurality of wheels may be connected to the driving device, and at least part of the plurality of wheels may be connected to the brake device, have.
In addition, a marine crane capable of moving the boom may be provided, wherein the driving device is connected to half of the plurality of wheels and the brake device is connected to the other half of the plurality of wheels.
According to the embodiments of the present invention, operation can be performed without greatly deteriorating the structural stability of the boom compared to conventional marine cranes, and maintenance and repair of the boom can be easily performed.
Further, there is an effect that the range in which the boom can lift the heavy object can be wider than the conventional one.
