Description

Method for transporting heavy materials in marine floating structures and apparatus for transporting heavy materials therefor {Transferring Method and Transferring Apparatus of Load in Column Structure}

The present invention relates to a heavy material conveying method and a heavy weight conveying apparatus for the same in the marine floating structure, specifically, floating in the sea vertically installed in the sea, such as a wind power tower, the main tower of the bridge, etc. In the column structure to be heavy, a heavy weight transfer method that can be easily transported by a transport device of the pulley configuration including a winch disposed in the hollow of the column structure, such as a wind turbine, the uppermost connecting structure, and the like It relates to a heavy material conveying device for.

In relation to renewable energy, there is a growing interest and need for wind power generation at sea. In such offshore wind power generation, it is necessary to install a wind power tower, which is a columnar structure in which a wind turbine is installed at the top. When the wind power tower is made of concrete for preventing salt, etc., a slip form method is generally used. In other words, while the formwork is raised in stages by pouring concrete in the field to produce a wind power tower in the form of reinforced concrete structures.

On the other hand, in recent years, as the demand for long bridges such as cable-stayed bridges and suspension bridges increases, construction of the pylons is being actively performed. It is common that the main tower of such bridge is also made of cast-in-place concrete using the slip foam method.

In the case of column structures such as wind towers or pylons, the heavy weights, such as wind turbines, support for main suspension lines, other machinery and top structures for equipment installation, are to be installed at the top. In general, even if the construction site of the column structure is at sea, it is possible to construct the column structure by placing concrete in a vertical state using the slip foam method up to the required height. There are several problems.

The most common method is to lift the weight (M) to the cable using a crane 200 by floating a ship on the sea. FIG. 1 is a schematic conceptual view showing a state in which a heavy object is lifted to an upper end of the columnar structure 100 using the crane 200 installed in the marine vessel. In particular, when the lower part of the column structure is present in the water can not only raise the weight using the crane 200 installed in the vessel, in this case, due to the instability of the vessel is very difficult to work as well as the weight (M) Collision with the columnar structure 100 has a problem that the possibility of damage to the heavy or columnar structure is very high.

On the other hand, Figure 2 is a schematic conceptual diagram showing a state in which the tower crane 300 is installed, it may be considered to install the tower crane 300 around the columnar structure 100 as shown in FIG. In the case of the tower crane 300, the lower part of the tower crane 300 must be fixedly installed on the ground. Therefore, when constructing the columnar structure 100 in the deep sea, the installation of the tower crane itself is very difficult and expensive and time-consuming. Since it is a waste of construction, it is not suitable for use in the columnar structure (100).

On the other hand, the Republic of Korea Patent No. 10-806661 discloses a prior art for raising the weight using a winch device installed on the ground. However, in the case of the above-described prior art, the winch device should be installed on the ground, but the winch device cannot be installed on the sea bottom, and thus cannot be used in the case of a column structure constructed at sea. In addition, since the winch device is installed on the ground, the length of the cable becomes longer, and thus, there are disadvantages such as an increase in cost and a limitation of a weight lifting range.

Since the lower part of the column structure constructed in the sea is submerged in water, there is a considerable difficulty in raising the weight (M) to the upper part of the column structure, and the construction cost is greatly increased. Therefore, the proposal of a technology that can solve this is very urgent situation.

See Republic of Korea Patent Publication No. 10-806661 (2008. 02. 26. notification).

The present invention was developed in order to overcome the limitations of the prior art as described above and to meet the necessity of the technical field, and specifically, even in a column structure that is constructed at sea so that the lower part is submerged in water, an easy and economic method of weighting. An object of the present invention is to provide an apparatus and a method for lifting a column structure to an upper portion thereof.

In order to achieve the above object, in the present invention, a horizontal platform having a hollow columnar structure extending in the longitudinal direction through the transverse direction and fixed to the upper portion of the columnar structure and the first pulley wheel is installed; A rail mounting frame having a lower portion coupled to the horizontal platform and installed above the top of the column structure; Arranged in the transverse direction while being supported by the rail mounting frame, the second pulley wheel is installed on one side and the third pulley wheel is movable to the other side and is parallel to the horizontal platform at a distance from the top of the column structure. A horizontal rail and a winch device installed on the horizontal platform, the winch device being located inside the hollow of the column structure, and one end wound around the winch device, and the other end of which has a first pulley wheel, a second pulley wheel, and a third It includes a lifting cable coupled with the heavy object to be lifted past the pulley wheel sequentially; When the winch device is operated in the state where the horizontal platform 10 is installed on the upper part of the column structure, the lifting cable is pulled up to lift the weight, and when the lifting device is lifted to a height higher than the upper end of the column structure, the third pulley wheel is horizontal along the horizontal rail. There is provided a heavy material conveying apparatus in a marine column structure, which has a configuration of moving and placing a heavy object above the upper end of the column structure.

In addition, the present invention comprises the steps of installing the horizontal conveyance device is coupled to the upper portion of the weight structure of the present invention the column structure; Operating the winch device to pull the lifting cable to lift a heavy object to a height above a top of a column structure; Moving the third pulley wheel along a horizontal rail to position the weight above the upper end of the column structure; And the weight of the lifting structure is provided by lowering the weight by lowering the weight to install on the upper end of the column structure.

In the present invention as described above, one side of the horizontal platform on which the first pulley wheel is installed, the balance weight for balancing can be provided in a movable state along the horizontal platform, in this case, lifting the weight When horizontally moving, the balance weight can be moved along the horizontal platform to maintain balance.

On the other hand, in the construction of the heavy weight conveying device in the present invention as described above, the rail mounting frame, a plurality of vertical members and the lower end is coupled to the horizontal platform, disposed across the vertical member and the horizontal rail is coupled It may be configured to include a horizontal connecting member.

The present invention has a configuration in which the winch device for winding or releasing the lifting cable for raising the lifting object weight is located in the hollow at the upper end of the column structure, so that the winch device is always above the water surface even when the column structure is installed at sea. Therefore, there is an advantage that can be easily operated at any time without a special waterproof measures.

That is, according to the present invention, even when the columnar structure is constructed at sea, the lifting cable can be wound or unwound without lifting a ship for a crane or installing a tower crane with the lower part fixed to the seabed. The winch device is positioned above the surface of the water and has the advantage of being able to easily lift and transport a heavy object to a desired height by using a pulley operation using a lifting cable.

Furthermore, in the present invention, there is no limit to the distance to lift and transport the heavy material after installing the heavy weight conveying device on the upper end of the column structure, even if the height of the column structure is high enough to be difficult to reach the tower crane or rack-mounted crane This has the advantage of being able to easily lift and install heavy objects up to its high position.

In particular, since the winch device in the present invention can be located near the upper end of the column structure on which the heavy weight is placed, the distance from the winch device to the heavy weight is close, and thus the length of the lifting cable used for lifting and transporting the heavy weight In addition, it is possible to reduce the costs associated with the use of the lifting cable, as well as to significantly reduce the time and cost of winding and unwinding the lifting cable.
