Description

Technical Field

[0001] This invention relates to a replacement device for a negative pressure sinking device for a barrel foundation. Background Technology

[0002] In recent years, my country's offshore wind power projects have developed rapidly. However, the hydrological and geological conditions of wind farms are becoming increasingly harsh and complex, making the construction of offshore wind power projects using traditional monopile and high-pile cap structures increasingly difficult and costly. Bucket foundations, as a type of non-driven shallow foundation, have a large diameter and small height. They typically utilize negative pressure sinking equipment to achieve suction-force sinking, which is more economical in terms of engineering exploration costs and steel consumption. Currently, domestic and international bucket foundation sinking construction mainly uses corresponding negative pressure sinking equipment based on various foundation structures. This often results in the need for backup sinking equipment for each type, leading to redundancy and high costs. Therefore, it is necessary to expand the applicability of existing negative pressure sinking equipment and its replacement devices. Summary of the Invention

The height of the four first precision positioning guide tubes is the same as the height of the barrel foundation docking seat. The lower ends of the four second precision positioning guide tubes are fixed on the top surface of the barrel foundation. The four second precision positioning guide tubes are located on the periphery of the barrel foundation docking seat in a one-to-one correspondence with the four support columns of the second barrel foundation docking device. The height of the four second precision positioning guide tubes is equal to the height of the barrel foundation docking seat plus the distance from the bottom of the device connection frame of the second barrel foundation docking device to the top of the equipment installation frame. The four connecting rods on the first equipment frame of the first negative pressure sinking device are inserted one by one into the four first precision positioning guide tubes of the first barrel base docking device until the bottom frame of the first equipment frame sits on the top of the four first precision positioning guide tubes and the top of the barrel base docking seat; the first negative pressure sinking device is locked on the barrel base docking plate of the barrel base docking seat by four hydraulic locks installed on the first equipment docking plate of the first equipment frame. The second equipment frame of the second negative pressure sinking device is located on the equipment mounting frame of the second barrel base docking device, and the second negative pressure sinking device is locked to the second equipment mounting plate of the second barrel base docking device by four hydraulic locks installed on the second equipment docking plate of the second equipment frame; After the first negative pressure sinking device is lifted away from the first barrel base docking device, the four support columns on the second barrel base docking device are inserted into the four second precision positioning guide tubes of the first barrel base docking device one by one, until the device connecting frame on the second barrel base docking device sits on the top of the four second precision positioning guide tubes. The second barrel base docking device is then locked on the barrel base docking plate of the barrel base docking seat by the four hydraulic locks installed on the device connecting plate.

The replacement device for the negative pressure settling device for a barrel foundation according to claim 1, characterized in that, The hydraulic lock on the first equipment docking plate includes a hydraulic cylinder and a chuck; the rear end of the cylinder body of the hydraulic cylinder is hinged to the top surface of the first equipment docking plate; the chuck is inverted ω-shaped, the rear end of the chuck is hinged to the end of the piston rod of the hydraulic cylinder, and the middle part of the chuck is hinged to a hinge seat fixed on the top surface of the first equipment docking plate and located at the edge of the upper locking opening, so that the front part of the chuck is located in the upper locking opening.

3. The replacement device for the negative pressure settling device for a barrel foundation according to claim 1, characterized in that, The first barrel base docking device also includes two first coarse positioning guide rods and two second coarse positioning guide rods; The lower ends of the two first thick positioning guide rods are fixed on the top surface of the barrel foundation and are located on the transverse center line of the barrel foundation docking seat, and are symmetrically located on both sides of the barrel foundation docking seat. The spacing between the two first thick positioning guide rods is adapted to the plane length of the first equipment frame. The lower ends of the two second thick positioning guide rods are fixed on the top surface of the barrel foundation and are located on the longitudinal center line of the barrel foundation docking seat, and are symmetrically located on the front and rear sides of the barrel foundation docking seat. The spacing between the two second thick positioning guide rods is adapted to the plane width of the second equipment frame. The upper parts of the two first thick positioning guide rods and the upper parts of the two second thick positioning guide rods are each bent outward by 30° to 45°. The upper parts of the four first precision positioning guide tubes are connected by two first transverse reinforcing tubes and two first longitudinal reinforcing tubes; A second transverse reinforcing tube is connected between the upper parts of the two second precision positioning guide tubes located on the front side of the barrel base docking seat and between the upper parts of the two second precision positioning guide tubes located on the rear side of the barrel base docking seat; each of the two second transverse reinforcing tubes is connected to the nearest first transverse reinforcing tube by two short longitudinal tubes. Two first thick positioning guide rods are connected to two first longitudinal reinforcing tubes in a one-to-one correspondence; two second thick positioning guide rods are connected to two second transverse reinforcing tubes in a one-to-one correspondence.
