Retractable adjustable boarding device

Abstract

The invention provides a retractable adjustable boarding device, and belongs to the technical field of ocean engineering. A retractable adjustable boarding device comprises a rod system spiral lifting assembly, a gear assembly, a bridge and a retractable step ladder, and the rod system spiral lifting assembly axially extends and is placed on a breakwater platform; the bridge is connected with the rod system spiral lifting assembly and arranged in the rod system spiral lifting assembly in a contractible mode, and when the bridge is in a working state, the bridge extends in the horizontal direction relative to the sea level through the gear assembly. And the telescopic step ladder is fixed at the tail end of the bridge. When the size and the height of a berthing ship body are changed, the boarding device can be matched to a proper contact position with a ship deck through the bridging length and the lifting change of the rod system spiral lifting assembly, and the flexibility and the convenience of the boarding process are improved. And meanwhile, the telescopic horizontal bridge can be retracted into the device when the device is in a non-working state, so that the purpose of protecting the service life of the structure is achieved.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a retractable and adjustable boarding device. Background technique [0002] In recent years, with the continuous exploration and development of the marine field, various types of marine floating structures have flourished, such as offshore wind wave current power generation devices, offshore breakwater structures, offshore oil and gas development platforms, and so on. Wherein the offshore breakwater structure can be used as an entertainment place to carry out leisure and entertainment activities such as fishing and viewing, and it is also possible to directly take a motorboat to go out to sea from the offshore breakwater. [0003] As a fixed place, the offshore breakwater requires the boarding ladder used for disembarking and disembarking the ship to be used as a fixed device for a long time. However, in the process of disembarking and disembarking from the offshore br...

Problems solved by technology

[0003] As a fixed place, the offshore breakwater requires the boarding ladder used for disembarking and disembarking the ship to be used as a fixed device for a long time. However, in the process of disembarking and disembarking from the offshore breakwater, the traditional boarding ladder is often difficult to adjust after installation. When ships of different sizes are berthing or tourists are boarding the ship, the ship will have a certain degree of horizontal displacement with the movement of the waves, which will easily cause the original boarding ladder to no longer adapt due to problems such as installation angle or ladder length. New ships or new conditions need to be disassembled and assembled again; at the same time, the connection between the two ends of the traditional boarding ladder and the ship and boarding platform is in the form of lap joints. As the ship moves up and down in the water and moves horizontally, this rigid contact The structural stability is poor. For tourists with poor sense of balance, there are certain safety hazards in the process of boarding. Therefore, the traditional boarding ladder has problems such as low flexibility and poor stability, and cannot meet the needs of ship deck positions under different conditions. match, more restrictive
