The present invention relates to a large support tower dedicated to mounting a rudder horn, which is free to move in a dock and is easy to install and release when mounting a rudder horn of a large ship. It consists of a driving support that can support and support, a support that can support high volume, a height adjuster that can adjust height, and a screw jack (SCREW-JACK) that comes in contact with the hull to facilitate the installation process by reducing drying labor and simplifying work. It is to provide a support tower dedicated to the installation of a rudder horn.

In general, a stern block is placed in a dock to install a rudder horn mounted on a stern. To this end, a support structure for supporting a ship in a dock is arranged and a stern block is mounted on a support structure by a goliath crane. After mounting, install the rudder horn.

The conventional support structure was supported by distributing a plurality of supports 10 to the left and right sides of the stern block as a support 10 in the form of a pipe that supports a weight of about 30 tons as shown in FIG. 1.

Due to this work method, the following work problems are raised.

First, the support 10 is arranged according to the weight of the structure, but as the weight increases, the quantity of the support 10 increases, and safety problems such as work loss and fall risk occur when the support 10 is installed and dismantled. There are many difficulties in work, such as having to move to a crane or forklift every time it moves.

In addition, the height of each support 10 should be different according to the shape of the stern, and must be provided in accordance with its size every time, and there is no place for the worker to install, so it is cumbersome and dangerous to install on another structure. There is a problem that must be done.

The present invention has been made to solve the conventional problems as described above, the object of which is to move and support by using the hydraulic pressure to be free to move in the dock, the installation and release smooth when mounting the rudder horn of a large vessel It consists of a driving support, a support that can support high volumes, a height adjustment that can adjust the height, and a screw jack that abuts on the hull, so that the installation process can be easily carried out by reducing the drying labor and simplifying work. This free and supportable structure can be safely seated so that productivity can be improved due to the efficiency of the worker's work, the risk of worker's fall and falling to surrounding objects is reduced, and the heavy weight can be withstood. It is to provide that only the support structure of the installation arrangement is possible.

In other words, it provides a driving support tower dedicated to the rudder horn installation to improve productivity and simplify the work.
