Description

Technical Field

[0001] The invention relates to the technical field of offshore hoisting construction, and in particular to an offshore cast-in-place beam steel bar integral hoisting construction device. Background Art

[0002] There are many unique challenges in offshore cast-in-place beam reinforcement construction, especially the complexity and uncertainty of the offshore environment, which puts higher demands on construction safety and efficiency. Traditional offshore cast-in-place beam reinforcement construction methods often rely on relatively simple lifting equipment, which can still meet construction needs when the wind and waves are small and the working environment is relatively stable.

[0003] However, when encountering severe weather conditions, especially when there are strong winds and waves at sea, traditional lifting equipment often cannot guarantee the stability and safety of construction. For example, the offshore lifting devices proposed in Chinese Patent Publication No. 217126745 and Chinese Patent Publication No. 115744675 have the above-mentioned problems. Specifically, when there are strong winds and waves at sea, the offshore lifting equipment is prone to shaking or capsizing, which may cause construction interruptions and even lead to safety accidents. In addition, the offshore lifting equipment is relatively simple in structural design and function, lacks sufficient flexibility and adaptability, and is difficult to meet the complex and changeable offshore construction needs. For example, when encountering extreme weather such as storms, traditional lifting equipment often cannot quickly adjust its status to cope with the harsh environment, resulting in equipment damage or injuries to construction personnel.

[0004] In order to solve these problems, the industry urgently needs a new type of offshore cast-in-place beam and steel bar integral lifting construction device that can adapt to the complex offshore environment and improve construction stability and safety. This device has stronger wind and wave resistance, higher level of automation and more flexible structural design. It can significantly improve the safety and efficiency of offshore cast-in-place beam and steel bar construction, and provide more reliable guarantees for large-scale structure construction such as offshore bridge construction, so as to cope with various challenges in offshore construction.

[0052] In offshore bridge construction, especially in sea areas with strong winds and waves, the device can significantly improve the safety and efficiency of construction; in large offshore structure construction, such as offshore platforms, offshore wind power generation facilities and other construction scenarios that require cast-in-place beam and steel structure; in construction projects that require rapid deployment and evacuation, since the device has a folding structure, it is easy to deploy and evacuate quickly, so it is very suitable for those projects that require rapid response and flexible adjustment of construction plans; in the event of severe weather such as storms, the device can be quickly folded and retracted to reduce the impact of weather on construction and ensure the safety of construction workers and the integrity of equipment.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
