Abstract

The invention discloses a gangway ladder base with a lifting function, which comprises a gangway ladder, wherein the base at the bottom of the gangway ladder is driven by a gangway ladder supporting structure, the gangway ladder supporting structure comprises a supporting plate fixed at the bottom of the base, the supporting plate is connected with a lifting device of a ship structure, the lifting device comprises a fixed plate connected with the ship structure, the supporting plate is driven by a lifting oil cylinder on the fixed plate, lug plates at two ends of the lifting oil cylinder are connected with pin holes at the edge of the fixed plate by a low-position bolt and a high-position bolt, and the supporting plate slides on the ship structure by rails at two sides of the fixed plate. Realize through this application that the gangway ladder can go up and down to not co-altitude to satisfy normal use gangway ladder when ocean platform has co-altitude with the external world.

Description

Accommodation ladder base with lifting function

Technical Field

The invention relates to the technical field of marine ships, in particular to a gangway ladder base with a lifting function.

Background

The gangway ladder is a movable passage facility for the ocean platform and the outside traffic, and is used for transporting the ocean platform and the outside personnel. However, due to the design limitation, when the height difference between the ocean platform and the outside is large, the height of the platform can be adjusted to meet the transportation requirement, so that the time is wasted, and the cost is increased.

Disclosure of Invention

In order to solve the problems, the invention discloses a gangway base with a lifting function.

The technical scheme of the invention is as follows: the utility model provides a gangway ladder base with raising and lowering functions, including the gangway ladder, the base of gangway ladder bottom drives through gangway ladder bearing structure, gangway ladder bearing structure is including the backup pad that is fixed in the base bottom, the backup pad links to each other with hull structure's elevating gear, elevating gear includes the fixed plate that links to each other with hull structure, the backup pad drives through the lift cylinder on the fixed plate, the otic placode at lift cylinder both ends links to each other through the pinhole at low-order bolt and high-order bolt and fixed plate edge, the track that the backup pad passes through the fixed plate both sides slides structurally at the hull.

Furthermore, the stroke stress rate of the hydraulic oil cylinder is greater than the distance between two pin holes connected with the lug plates, and the distance of each lifting of the hydraulic oil cylinder is the distance between the two pin holes.

Furthermore, a row of pin holes are formed in the edge of the fixing plate.

The invention has the advantages that: realize through this application that the gangway ladder can go up and down to not co-altitude to satisfy normal use gangway ladder when ocean platform has co-altitude with the external world.

Detailed Description

For the purpose of enhancing an understanding of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.

As shown in fig. 1-3, a gangway base with lifting function comprises a gangway 1, a base 2 at the bottom of the gangway 1 is driven by a gangway supporting structure, the gangway supporting structure comprises a supporting plate 3 fixed at the bottom of the base 2, the supporting plate 3 is connected with a lifting device of a ship body structure 4, the lifting device comprises a fixing plate connected with the ship body structure, the supporting plate 3 is driven by a lifting oil cylinder 7 on the fixing plate 5, the shell of the lifting oil cylinder 7 is connected with the supporting plate 3 into a whole, the edge of the fixing plate 5 is provided with a row of pin holes 6, lug plates 8 at two ends of the lifting oil cylinder 7 are connected with the pin holes 6 at the edge of the fixing plate 5 by a low-position pin 9 and a high-position pin 10, the supporting plate 3 slides on the ship body structure 4 by rails 11 at two sides of the fixing plate 5, the stroke response rate of the lifting oil, the distance of each lifting of the lifting oil cylinder 7 is the distance between the two pin holes 6.

The working principle is as follows:

the gangway ladder base is in fixed state, and the base concrete action when rising: firstly, after confirming that the low-position bolt is in the pin hole, the high-position bolt is pulled out of the pin hole; then, the lifting oil cylinder enters oil and begins to extend out to drive the supporting plate to move upwards until the position of the next pin hole; then inserting the high-position bolt into the pin hole; then, the low-position plug pin 24 is pulled out from the pin hole; then, the lifting oil cylinder begins to contract to the next pin hole position, the low-position bolt is inserted into the pin hole, a lifting action is completed, and the lifting operation can be continuously carried out by repeating the circulating action.

The descending process is similar in principle and operates in reverse.

This application drives gangway ladder base altitude mixture control through elevating gear, has increased the altitude range that docks mutually with the platform, has overcome the platform and has used gangway ladder during operation to add the pressure through conventional platform self and carry or the complexity of drainage operation adjustment platform height at sea, very big saving working cost and time, improvement work efficiency.
