Description

Technical Field

[0001] The utility model relates to the technical field of excavators, in particular to a multi-functional excavation device suitable for offshore construction. Background Art

[0002] An offshore excavator is a mechanical device specifically used for underwater excavation and construction. It completes various work tasks by controlling the actions of the excavation device. The hydraulic system provides power for the offshore excavator and controls the movement of each component, enabling the excavator to perform excavation, cleaning, and other construction work on water. In addition, the offshore excavator also has the ability to work underwater. By adjusting the balance of the floats and the hull, the excavator floats on the water surface. By operating the control lever or button, the driver can control the movement and actions of the excavator, thereby realizing excavation, cleaning, and other construction work underwater. Maintaining the balance state of the offshore excavator during work is a key issue. At the same time, when floating on the sea, it is easy to cause insufficient driving force of the robotic arm during the excavation process. The offshore excavator also needs to adapt to the construction environment of different underwater soils.

[0003] Chinese Patent Authorization Publication No. CN221608972U provides a ship-type excavator with upper and lower floating crawlers for submersible walking. This utility model relates to the technical field of construction excavation equipment for water environment treatment, and specifically discloses a ship-type excavator with upper and lower floating crawlers for submersible walking, including a hull. An excavation body is fixedly installed on the hull. A crawler-type traveling body is provided below the hull. The hull is floatingly connected to the crawler-type traveling body through a floating lifting connecting rod assembly, enabling the hull to rise and fall with the water depth. The crawler-type traveling body is equipped with a load-bearing frame, and a load-bearing and stabilizing device is provided at the top of the load-bearing frame. A linkage shaft member and a stabilizing block are arranged above the load-bearing and stabilizing device on the hull. Before underwater excavation operations, the piston shaft of the hydraulic cylinder pushes the linkage shaft member downward to abut against the bottom of the stabilizing block and the load-bearing and stabilizing device, so that the hull is placed on the crawler chassis instead of floating on the water surface, and the whole machine is firmly placed. When operating in deep water, the hull will not sway and bump under the action of the excavation force, ensuring that the whole machine is as stable and reliable as operating on land.

[0004] The above method has the following problems: The hull is too small to enable the excavator to maintain good working balance in deep water. Relying on the lifting device and the load-bearing frame makes it difficult for the excavator to operate in deeper water. It is impossible to perform targeted operations on different underwater soils, and it cannot provide good support and drive for the robotic arm during the operation of the excavator.
