Abstract

The utility model discloses a combined type telescopic gangway ladder system for a deep sea drilling ship. The combined type telescopic gangway ladder system comprises a telescopic gangway ladder (1), a power motor (2), a pilot rope ladder (3), a sliding winch (4) and a guide rail (5). The telescopic gangway ladder (1), the power motor (2) and the guide rail (5) are installed on a deck (6) respectively. The pilot rope ladder (3) is installed on the sliding winch (4). The sliding winch (4) is installed on the guide rail (5) in a slidable mode. According to the combined type telescopic gangway ladder system for the deep sea drilling ship, the gangway ladder and the pilot rope ladder are combined together for usage, wherein the gangway ladder and the pilot rope ladder are independent originally, and therefore the installation length of the gangway ladder is reduced, space occupied by the deck is reduced, and the probability of optimization is provided for the layout of the whole deck; and meanwhile, the combined type telescopic gangway ladder system for the deep sea drilling ship can be assembled in advance in a modular mode off a ship and then installed integrally on the ship, and therefore working efficiency can be improved greatly, and a construction period can be shortened.

Description

Deep sea drilling ship composite extendible gangway ladder system

Technical field

The utility model relates to a kind of deep sea drilling ship composite extendible gangway ladder system.

Background technology

In the prior art, according to the requirement of IMO, every boats and ships must be equipped with pilot ladder and gangway ladder, and in conventional boats and ships, light draft and moldeed depth are all smaller, and the gangway ladder length that is equipped with is also less; Deck area is comparatively spacious for the space simultaneously, leaves the space of abundance for the layout of gangway ladder; In the design of deep large drilling ship, large-scale FPSO or multi-functional supply boats and ships, moldeed depth is all very big, the gangway ladder length of thinking outfit is also corresponding very long routinely, but because particularity and the complexity of this type ship oceangoing ship, the degree of utilization of between deck space is very high, and oversize gangway ladder can take very big between deck space, directly influences the layout on whole deck, arrange for miscellaneous equipment or structure Design and to bring a lot of difficult points, will bring more fringe cost simultaneously for this reason.

The utility model content

The purpose of this utility model provides a kind of deep sea drilling ship composite extendible gangway ladder system that gangway ladder and pilot ladder can be used in combination.

The technical scheme that the utility model adopts for achieving the above object is: a kind of deep sea drilling ship composite extendible gangway ladder system, comprise flexible gangway ladder (1), power motor (2), pilot ladder (3), crab winch (4) and guide rail (5), described flexible gangway ladder (1), power motor (2) and guide rail (5) are installed in respectively on the deck (6), pilot ladder (3) is installed on the crab winch (4), and crab winch (4) slidably is installed on the guide rail (5).

When at shallow draft or deposit highly big and flexible gangway ladder installation length when restricted, described crab winch (4) slides at guide rail (5), transfer pilot ladder (3) after finding the appropriate location, the pilot is arrived on harbour or other boats and ships by pilot ladder from the gangway ladder lower platform.

When absorbing water deeply and being no more than 8m, can directly promote crab winch (4) and slide to select the appropriate location directly to transfer pilot ladder (3) at guide rail (5) to arrive on harbour or other boats and ships for the pilot.

A kind of deep sea drilling ship of the utility model composite extendible gangway ladder system, will be originally independently gangway ladder and the pilot ladder use that combines, shortened the installation length of gangway ladder, saved the usage space on deck, for the layout on whole deck provide more optimal may; Simultaneously this cover system also can be under ship modular assembling in advance, integral body installations of going on board then can be increased work efficiency so greatly, thus the shortening production cycle.

Description of drawings

Fig. 1 is the birds-eye view of a kind of deep sea drilling ship of the utility model composite extendible gangway ladder system.

Fig. 2 is the lateral plan of a kind of deep sea drilling ship of the utility model composite extendible gangway ladder system.

Among the figure: 1, flexible gangway ladder; 2, power motor; 3, pilot ladder; 4, crab winch; 5, guide rail; 6, deck.

The specific embodiment

As depicted in figs. 1 and 2, deep sea drilling ship composite extendible gangway ladder system, comprise flexible gangway ladder 1, power motor 2, pilot ladder 3, crab winch 4 and guide rail 5, flexible gangway ladder 1, power motor 2 and guide rail 5 are installed in respectively on the deck 6, pilot ladder 3 is installed on the crab winch 4, crab winch 4 slidably is installed on the guide rail 5, the utility model composite extendible gangway ladder system, at shallow draft or deposit under the situation that height is big and flexible gangway ladder 1 installation length of aluminum is limited, pilot ladder 4 slides at guide rail 5, find suitable position to transfer pilot ladder 3 later on, the pilot is arrived on harbour or other boats and ships by rope ladder from the gangway ladder lower platform; Under the situation of dark drinking water and be no more than under the situation of 8m, can directly promote pilot ladder 4 and slide to select the appropriate location to transfer pilot ladder 3 at guide rail 5 to arrive on harbour or other boats and ships for pilots.

The utility model composite extendible gangway ladder system, be divided into 5 parts at composition, its each part is all relatively independent for other parts, ship positionning on gangway ladder 1 and the power motor 2 at first will stretch, by the maximum coverage range of the definite gangway ladder of folding and unfolding test, locate the preliminary position of pilot's winch guide rail 5 then according to this scope; After pilot ladder 3 is installed on crab winch 4, and together be positioned on the guide rail 5, promoting crab winch 4 slides at guide rail 5, further adjust the exact location of guide rail 5 according to the coverage of gangway ladder 1, finally finish welding successively after various piece finds corresponding suitable position, the total system assembling finishes like this, can satisfy corresponding function and use, this assembling process also can be gone on board after the assembling of ship lower module formula and directly be welded, and will decide according to the actual construction situation of every boats and ships.
