Description

{Ladder Construction for Crossing of Parallel Moored Ships}

The present invention relates to a shipboard ladder structure for double row mooring, and more particularly, to a double row shipboard ladder structure capable of safely and conveniently traveling on both decks of ships when two ships having different elevations of deck within a dock are arranged side by side and simultaneously dried, To a double lane mooring ladder structure.

A typical dock is designed to berth a ship to dry, repair or moor (hereinafter referred to as "mooring"). This is because the clearance of the quay wall is designed to fit one vessel.

In recent years, docks and construction methods that work by making two ships side by side moored (hereinafter referred to as "double mooring") are of interest. When two moored vessels are operated by mooring, The efficiency of the work can be increased.

In the past, since the double stream mooring was not generalized, the research on the ladder or the bridge structure for going to both ships was insignificant.

Patent Document 1 discloses a 'ladder for lifting and lowering a ship' proposed by the present applicant.

The ladder structure disclosed in Patent Document 1 has a structure in which the height of the deck of the ship and the height of the ground surface of the seam are different or vary and the distance between the ship and the seam is changed, So that they can easily adapt.

The ladder structure disclosed in Patent Document 1 has been proposed as a structure for safely traveling between the inner wall of a dock and a ship. Therefore, there is a part to be used as a structure for passing between two ships of two ships.

For example, the ladder structure disclosed in Patent Document 1 has a structure in which the sea connecting portion 130 is not formed in a step shape but a slip prevention pattern 131 is formed on the swash plate 131. Therefore, the height of the ground of the ship and the deck of the ship If the difference is large, the inclination of the marine connection becomes too harsh and it is difficult and dangerous to rise and fall.

The base end of the moving block 121 is horizontally moved along the rail 110 on the ground through the driving wheel 125 and the floating connection part 130 is placed on the free end of the moving block 121 The load of the structure constituting the marine connecting portion is concentrated on the free end of the moving block 121, so that a large deflection moment is generated in the form of a so-called 'cantilever beam', so that the structural stability is lowered.

Specifically, the double lane mooring ladder structure comprises a first deck 10, a second deck 10 having a weight tower structure 100, a horizontal pathway structure 210 and a first beveled stair structure 220, A second ramped ladder structure 300, and an inclined flow structure 400 of the ladder structure 200 of FIG.

The weight tower structure 100 is fixed to the first deck 10 and supports the entire weight of the ladder structure. The weight tower structure 100 includes a frame 110 in which a plurality of beams and columns are combined.

The boarding ladder structure 200 includes a horizontal pathway structure 210 and a first inclined stepped structure 220 to allow the second deck 20 and the ladder structure to move up and down through a plurality of steps 224, And provides horizontal passageways by the horizontal top plate 212.

The stairs 224 are not tilted even in a change, and are kept constantly in the initial installation state at all times, thereby enabling a safe walking of the operator.

The second bevel step structure 300 has a structure in which the fixed end thereof is connected and fixed to the first deck 10 and the weight tower structure 100 and the free end thereof extends downward toward the second deck 20 And the fixed end and the free end are connected by a plurality of steps 314 (see FIG. 2).

The second inclined step structure 300 is fixed to the first deck 10 and the weight tower structure 100 so that the inclination of the first and second ships does not change due to the change of the elevation of the first and second ships, It is a fixed type structure that maintains the slope. Therefore, the stairs 314 are not inclined even when the height of the first and second ships is changed or the distance is changed, so that the first installation state is always kept constant, thereby allowing the operator to walk safely.

The fixed end of the second bevel step structure 300 is connected to the weight tower structure 100 by a hinge axis 330 to increase the structural stability of the second bevel stair structure 300 and the structural stability of the entire ladder structure. And the free end is connected to the weight tower structure 100 by means of tension legs 304 so that the weight of the second inclined step structure 300 by the tension leg 304 .

In this case, as an auxiliary means for maximizing the structural stability of the second inclined step structure 300 and the structural stability of the entire ladder structure, the lower portion of the second inclined step structure 300 is attached to the side wall of the first ship with reinforcement supports 320 As shown in Fig.

The inclined flow structure 400 has a flat bottom plate 410 that provides a flat passage that an operator can walk on. And a safety guard 420 is installed on both sides of the flat bottom plate 410.

A roller 430 is mounted on the opposite end of the inclined flow structure 400 and the roller 430 is mounted on the upper surface of the horizontal top plate 212 of the horizontal passage structure 210, (Not shown).

Therefore, a change in height, a change in distance, or a shift in the forward and backward direction of the ship between the first vessel and the second vessel is caused by horizontal and vertical pivotal movements of one longitudinal end portion of the inclined flow structure 400, And is compensated by longitudinal rolling movement of the roller 430 at the opposite end.

One end of the planar bottom plate 410 of the inclined flow structure 400 is supported by the second inclined step structure 300 and the opposite end is supported by the horizontal top plate 212 of the horizontal pathway structure 210, A stable support structure is obtained in which both ends are supported without being subjected to an eccentric load as in the case of the moving block of Patent Document 1. In addition, in the inclined flow structure 400, the weight of the other structure is not loaded unlike the weight of the marine connection portion in the moving block of Patent Document 1, and the two ends of the inclined flow structure 400 are supported by the second inclined step structure 300, And the horizontal passageway structure 210. The horizontal passageway structure 210 shown in Fig.
