Safe and reliable full-rotation retractable gap bridge

Abstract

The invention relates to a safe and reliable full-rotation retractable gap bridge, which is characterized by comprising a base frame (1), wherein a rotation support (2) is arranged on the base frame (1); a gap bridge (5) is hinged to one end of the rotation support (2) and comprises a fixing gap bridge (5.1) and a movable gap bridge (5.2); the movable gap bridge (5.2) is connected with the fixing gap bridge (5.1) through a retractable device (5.3); a landing support (6) is fixed at one end, which is away from the fixing gap bridge (5.1), of the movable gap bridge (5.2); and a supply system (7) is also arranged on the safe and reliable full-rotation retractable gap bridge. By the safe and reliable full-rotation retractable gap bridge, supplies are conveyed safely and conveniently, personnel are transferred quickly, the dropping impact of the gap bridge is reduced, the service life of the gap bridge is prolonged, and the gap bridge is convenient to operate and repair.

Description

technical field [0001] The invention relates to a safe and reliable full-rotation telescopic bridge, which is mainly used for the passage or transfer of personnel and limited-weight materials between marine living platforms and offshore supply ships or marine drilling platforms. Background technique [0002] On offshore drilling platforms, it is often necessary to replenish or relocate materials or transfer personnel through offshore supply ships. The offshore drilling platform or offshore supply ship connects the marine living platforms through a bridge device, so as to transport materials and personnel. The bridge crossing device is controlled by the operator. The bridge crossing is first lifted, then turned and then lowered, so as to be erected on the deck of an ocean drilling platform or an offshore supply ship. [0003] However, due to the heavy weight of the bridge, when one end of the bridge is lowered on the deck, it is easy to generate shock vibration, thereby affe...

AI Technical Summary

Problems solved by technology

[0003] However, due to the heavy weight of the bridge, when one end of the bridge is lowered to the deck, it is easy to generate shock and vibration, which affects the service life of the bridge

[0004] And for some liquid and gas resources, it is necessary to transport the liquid and gas resources from the bridge device to the drilling platform again and again, which is inefficient and inconvenient

[0005] In the past, the control room was set on the slewing support. Since the bridge is set in front of the control room, it will affect the sight of the operator, thereby affecting the lapping efficiency of the bridge.

[0006] There are many parts on the slewing support, the connection structure is complex, and failures will occur during use. Once a failure occurs, a ladder needs to be repaired on the base frame, which is very inconvenient to repair and the repair efficiency is low.
