Description

Technical Field

[0001] This utility model relates to the field of marine engineering equipment technology, and in particular to a base for the overall hoisting of wave-compensated trestle and gangway support. Background Technology

[0002] With the deepening of human understanding of marine resources and continuous technological advancements, marine development activities are becoming increasingly frequent. The rapid development of offshore wind power, offshore oil and gas extraction, and marine scientific research has led to a rapid increase in the number of offshore facilities such as offshore operation platforms and offshore wind power platforms. These facilities are often located in sea areas far from land, requiring personnel to be stationed regularly or for extended periods for operation, maintenance, and management. Therefore, equipment capable of safely and efficiently transporting personnel from ships to these offshore facilities is particularly important, leading to the development of multi-degree-of-freedom wave-compensated piers.

[0003] Existing multi-degree-of-freedom wave-compensated trestle bridges face two major problems during offshore construction: First, existing multi-degree-of-freedom wave compensation piers at sea are generally welded and fixed directly to the main deck of the ship, making it impossible to move or replace the ship at will. When facing complex and ever-changing marine environments, it is not possible to flexibly change the ship to meet construction needs. Secondly, when the wave-compensated trestle is in operation, personnel need to enter the waiting area of ​​the trestle's gangway in advance. When the wind and waves are significant and it is difficult to maintain stability, personnel must wait for the trestle's gangway to return to standby mode before they can evacuate, increasing operational risks. These problems not only reduce the practicality and safety of offshore multi-degree-of-freedom wave-compensated trestle bridges but also limit their application in critical areas such as offshore wind power operation and maintenance. Utility Model Content

[0004] To address the technical problems of existing multi-degree-of-freedom wave compensation trestle bridges being welded and fixed to the main deck of ships, making it impossible to move or replace the ship at will, and the increased operational risks caused by personnel needing to enter the waiting area of ​​the trestle gangway in advance when the wave compensation trestle is in operation and having to wait for the gangway to return to standby mode before leaving when the wind and waves are strong and it is difficult to maintain stability, this utility model provides a base for the overall hoisting of wave compensation trestle bridges and gangway support.

[0005] The present invention provides a base for the overall hoisting and gangway support of a wave-compensated trestle, which adopts the following technical solution: A base for the overall hoisting and gangway support of a wave-compensated trestle bridge, comprising: The base is on which the slewing mechanism of the main body of the multi-degree-of-freedom wave-compensated trestle is connected; The supporting rest arm connected to the base has a gangway support point at its top. This gangway support point contacts the outer aluminum alloy gangway of the relatively telescopic and movable multi-degree-of-freedom wave compensation pier at sea. The outer side of the top of the supporting rest arm has a lifting point for overall hoisting. A waiting platform for personnel installed in the middle of the supporting rest arm; A trapezoidal frame for personnel boarding the gangway is connected to the personnel waiting platform and the base. A buffer platform is provided on the top of the trapezoidal frame.

[0006] Furthermore, the base is provided with a slewing connection hole, and the main slewing mechanism of the multi-degree-of-freedom wave compensation trestle is rotatably connected to the slewing connection hole.

[0007] Furthermore, the trapezoidal frame is installed on the upper part of the base.

[0008] Furthermore, the personnel waiting platform is connected to the base.

[0009] Furthermore, the lifting point installed on the top outer side of the supporting arm is a lifting lug for hoisting, and the lifting lug is connected to the rigging.

[0010] Furthermore, the gangway support points are covered with rubber material.

[0011] Furthermore, the main body of the multi-degree-of-freedom wave-compensated trestle at sea is equipped with movable lifting lugs.

[0012] Furthermore, the buffer platform includes a base platform and a side platform, and the included angle between the base platform and the side platform is greater than 90°.

[0013] In summary, the beneficial effects of this utility model are as follows: This utility model features a stable base and a trapezoidal frame. The base is connected to the rotating structure of the main body of the offshore multi-degree-of-freedom wave compensation trestle, breaking away from conventional fixed-ship offshore multi-degree-of-freedom wave compensation trestle. It not only provides a solid foundation for the entire trestle but also allows for flexible replacement of the operating vessel according to actual engineering needs. In offshore wind power operation and maintenance, this basic structure provides strong support for maintenance personnel, enabling them to complete inspection, repair, and maintenance tasks more safely and efficiently.

[0014] In terms of stability and safety, this invention incorporates several innovative measures in its base design. The personnel waiting platform and trapezoidal frame are designed independently of the main structure of the multi-degree-of-freedom wave-compensated pier at sea, allowing personnel to pass through the gangway sequentially during sea traversal. In case of emergency, remaining personnel can also quickly evacuate from the trapezoidal frame. This design provides a fast and safe passage for personnel to access the gangway, further enhancing safety and convenience.

[0015] Furthermore, the supporting rest arm design not only enhances the stability and overall load-bearing capacity of the base, but also provides support for the gangway in standby mode, eliminating the need for additional rest arm design and fixing work. This further improves the convenience of multi-degree-of-freedom wave-compensated piers at sea.

[0016] These innovative designs collectively constitute the core advantages of this utility model's base, enabling the multi-degree-of-freedom wave compensation trestle at sea to break free from the constraints and influences of ships. It can flexibly change operating vessels according to actual needs, without requiring additional installation and fixing work. This greatly improves its economy and applicability in the field of offshore wind power operation and maintenance, and has a wider range of application prospects. Attached Figure Description
