Description

Cross skid beam structure < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for loading out a ship or a structure, and more particularly, to a cross-skid structure capable of performing longitudinal and lateral skipping and performing a weaving operation.

Generally, in order to dry a ship, a dock is provided on the coast, the ship is dried inside the dock, and then the dock is opened to inflow the seawater into the inside of the dock so that the ship is launched.

However, when the space for constructing the dock becomes insufficient, the cost for constructing the dock increases, and the ship is dried in the dock, there is a problem that ships under construction are often damaged due to natural disasters such as typhoons in summer. After the ship is dried, it is transferred to a floating dock to develop a land-based drying technique that launches a ship or an offshore structure.

For example, the above-mentioned land drying technique is a method in which a ship or a marine structure is mounted on a skid beam installed on the ground, or the ship or a marine structure is dried and then mounted on a skid beam, The sea structure is then loaded-out to a floating dock floating in the sea, and then the floating dock is submerged.

Although the load-out equipment such as a skid beam, a skid shoe, and a hydraulic lift used in the land-type drying method uses a method of launching in the longitudinal direction, in the case where the space for drying the ship is narrow, There has been a problem of reducing the productivity of ships or marine structures.

As shown in FIG. 1, the skid beam 10, which is installed on the ground and has reinforcing beams 15 on both sides thereof, is installed in the space as shown in FIG. 2 so that the ship or the sea structure can be dried or loaded out in a narrow space, However, in the process of installing the skid beams 10 in an intersecting manner, the skid beams 10 and the reinforcing beams 15, which are mutually interfering with each other, must be cut and modified So that it takes a long time and a lot of labor is consumed.

In addition, when the weighing operation is performed before the ship or the marine structure is loaded out, it is not possible to secure a space for installing a jig (not shown) provided with the hydraulic jack, so that the reinforcing beam 15 welded to the skid beam 10 is removed There is a problem that it is necessary to perform skewing for load-out after attaching the removed reinforcing beam 15 after performing the weaving operation, and thus there is a problem that the working time and labor are unnecessarily consumed.

It is an object of the present invention to integrate a crossing skid beam and a support jig so that a ship or an offshore structure can be transferred longitudinally or laterally so that the ship or an offshore structure can be loaded out even in a narrow space, And it is an object of the present invention to provide an intersecting skid structure that does not need to perform a correction operation and can perform a weighing operation without removing a reinforcing beam.
