Description
Technical Field
The utility model relates to a pile foundation construction technical field specifically indicates a marine wind power pile foundation hoists and erects turning device.
Background
The offshore wind power pile foundation is a large-diameter overlong steel pile, and the single weight of the pile foundation can reach more than 1000 t. When the offshore wind power pile foundation is installed, a double-floating-crane hoisting scheme or a single-floating-crane and underwater centralizing scheme is conventionally adopted. When the double-floating-crane hoisting is adopted, after the pile foundation transport ship reaches the designated position and is positioned, the two floating cranes simultaneously lift the crane to lift the pile foundation from the transport ship and sink the pile foundation into water. Through the cooperation of the two floating cranes, the position and the posture of the pile foundation can be easily adjusted in the hoisting process. In actual operation, only two floating cranes are needed in the process of hoisting the pile foundation, and one floating crane can be independently constructed for all other constructions, so that the method does not fully utilize the floating crane resources, and the construction cost is increased.
When the scheme of combining the single floating crane with the underwater righting is adopted, the floating crane firstly lifts the whole pile foundation horizontally from a transport ship to be sunk into the sea, then the hoisting cable at the bottom of the pile foundation is untied underwater by means of an ROV (remote operated vehicle), and the hoisting cable fixed at the top of the pile foundation is lifted by a crane to finish the work of righting the pile foundation. The method reduces the construction cost, but increases the construction difficulty and uncertainty factors during ROV underwater operation, and when sea storms are large, the position and the posture of the pile foundation are difficult to control by a single hoisting steel wire rope.
In order to overcome this problem, there is the chinese utility model patent of "a novel turning device that is used for overweight steel-pipe pile hoist and mount of overlength" the name of patent number "CN 201520204592.9" at present, this patent has introduced a flip structure for steel-pipe pile, this structure is provided with a hinged-support, fixed knot through on the steel-pipe pile constructs fixedly with the hinged-support, the steel-pipe pile lifts by crane the upset through hoisting equipment, the steel-pipe pile is followed the hinged-support upset and is vertical state, whole pile structure that turns over is safe, light, economy, high efficiency, the back yard machine-shaping of being convenient for, reduce cost that can be fine, the raise the efficiency. However, the structure needs to be welded and fixed on the outer side of the steel pipe pile in advance, the fixed structure damages and destroys the steel pipe pile, and the construction which does not have requirements on the external structure of the steel pipe pile is good, but the wind power pile foundation which has strict requirements on the external structure is obviously inapplicable.
