Description

Technical Field

[0001] The utility model relates to the technical field of pile hammer hoisting, in particular to a pile hammer matching hoisting device. Background Art

[0002] Offshore pile sinking technology is one of the important processes in offshore wind power project construction. At present, in order to reduce construction costs, a single lifting device is used to lift the pipe pile and pile hammer. The lifting device first lifts the pipe pile to a suitable position and puts it into the water. Then the lifting device lifts the pile hammer to the top of the pipe pile, so that the pile hammer hits the pipe pile to achieve effective sinking of the pipe pile.

[0003] Since the pile hammer is relatively high, it is not easy for the staff to connect the wire rope on the lifting device to the lifting ring on the top of the pile hammer. Therefore, the staff pre-bolts a lifting rope to the lifting ring on the top of the pile hammer, and the length of the lifting rope is greater than the height of the pile hammer body, so that the lifting rope is away from the lifting ring of the pile hammer and falls to the bottom of the pile hammer. When lifting the pile hammer, the lifting device is connected to the lifting rope, thereby realizing the connection between the lifting device and the pile hammer.

[0004] When the lifting equipment lifts the pile hammer into the air, the lifting rope is vertically connected between the lifting equipment and the pile hammer, so the lifting rope increases the distance between the lifting equipment and the pile hammer. When the pile hammers of the same size are lifted to the same height, the pile hammer using the lifting rope needs a longer lifting time. Utility Model Content
