<p>The present invention provides a jack-up platform driving device having a fixing supporter. The jack-up platform driving device comprises a leg part having multiple vertical shafts with rack gears formed on both surfaces thereof; a spud can coupled to the bottom of the leg part, fixed while being in surface-contact with the seabed, and supporting the leg part; a fixing supporter connected to the outside of the leg part to be slid along the leg part, having connection parts arranged on the outer surface to be coupled to an offshore structure, and capable of moving up and down the leg part; and lifting units installed on one side of the fixing supporter, and connected to the rack gears to generate driving force for making the leg part slide on the fixing supporter. The jack-up platform driving device according to the present invention can be easily manufactured by reducing the number of the vertical shafts of the leg part, and can reduce the manufacturing costs of the offshore structure. The present invention can reduce the malfunctions of a jack-up platform and can facilitate the maintenance of the jack-up platform by having the structure simplified by reducing the number of gears. Also, the three-stepped gears and gear boxes connected to one driving motor can convert a rotary motion to a vertical motion and can provide a low-capacity driving effect.</p> |
