Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to a device for performing underwater pile foundation construction on a pile pipe during an offshore wind power pile foundation process. Background Art

[0002] At present, during the underwater pile foundation construction process of offshore wind farms, a pile pipe clamping device installed on a ship is used to clamp and guide the pile pipe. The shortcomings of the existing pile pipe clamping device for underwater pile foundation construction are: since the pile pipe is guided by the pile gripper with a ring-shaped fixed structure installed on the construction ship, when constructing pile pipes of different diameters, it is necessary to replace and install pile grippers of different sizes, which increases the construction cost and time. The offshore operation window time is extremely limited, which undoubtedly brings huge challenges to the construction; at the same time, when constructing in deep water, the pile pipe must be lengthened first, otherwise the top of the pile pipe cannot be guided by the pile gripper during the piling process due to insufficient length, and underwater cutting is required after the construction is completed, which is time-consuming, labor-intensive and ineffective. To this end, we propose an underwater pile foundation construction device to solve the above problems. Utility Model Content

[0003] 1. Technical problems solved:

[0004] In view of the deficiencies of the prior art, the utility model provides an underwater pile foundation construction device, which solves the problems raised by the background technology.

[0005] 2. Technical solution:

[0006] The utility model provides the following technical solution: an underwater pile foundation construction device, comprising a first base, a second base, a first semicircular clamping sleeve, a second semicircular clamping sleeve and an auxiliary rod;

[0007] A first side plate is welded on the top of the first base, a first hydraulic cylinder is installed on one side of the first side plate through a mounting frame, an output shaft of the first hydraulic cylinder located on the other side of the first side plate is fixed with a first semicircular sleeve through a flange, a second base is arranged on one side of the first base, a second side plate is welded on the top of the second base, a second hydraulic cylinder is installed on one side of the second side plate through a mounting frame, an output shaft of the second hydraulic cylinder located on the other side of the second side plate is fixed with a second semicircular sleeve through a flange, clamping plates are welded equidistantly on the inner sides of the second semicircular sleeve and the first semicircular sleeve, limiting sleeves are welded on both ends of one side of the first side plate and the second side plate, a sleeve is connected with a sleeve on one side through a threaded groove, an iron sleeve is fixedly provided inside the sleeve, an electromagnetic coil is provided on the outer side of the iron sleeve, an iron column is provided inside the iron sleeve, and a compression spring is fixed between the iron column and the iron sleeve through bolts.

[0008] Furthermore, a first connecting plate is welded equidistantly between the first base and the second base, and a second connecting plate is welded equidistantly between the first side plate and the second side plate.

[0009] Furthermore, triangular support plates are welded between the first base and the first side plate and between the second side plate No. 2 of the second base.

[0010] Furthermore, the sleeve is communicated with the limiting sleeve, and one side of the auxiliary rod is provided with slots corresponding to the iron column at equal distances.

[0011] Furthermore, docking posts are equidistantly welded at both ends of one side of the first semicircular ferrule, and docking grooves corresponding to the docking posts are equidistantly opened at both ends of one side of the second semicircular ferrule.

[0012] Furthermore, both ends of the top of the first side plate and the second side plate are welded with lifting ears.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] After the device is hoisted to the outside of the pile pipe on the seabed, the first hydraulic cylinder and the second hydraulic cylinder are opened to push the first semicircular clamping sleeve and the second semicircular clamping sleeve to move toward each other. After the first semicircular clamping sleeve and the second semicircular clamping sleeve are closed, the pile pipe is clamped and guided, so that pile pipes with different diameters can be conveniently constructed. At the same time, since the device of the utility model is directly placed in the sea for construction, it is convenient for the pile driver on the construction ship to drive the pile pipe into the seabed without the need to extend the pile pipe, so that construction can be carried out in deep water;

[0015] When the first hydraulic cylinder and the second hydraulic cylinder are opened, the electromagnetic coil is powered. After the electromagnetic coil is powered, the iron sleeve generates magnetism, causing the iron column to retract into the iron sleeve. At this time, the auxiliary rod can slide in the limit sleeve. After the first semicircular clamping sleeve and the second semicircular clamping sleeve clamp the pile pipe, the power supply to the electromagnetic coil is disconnected to make the magnetism in the iron sleeve disappear. At this time, the compression spring pushes the iron column to penetrate into the clamping plate and insert it into the corresponding clamping groove on one side of the auxiliary rod to fix the auxiliary rod, so that the closed first semicircular clamping sleeve and the second semicircular clamping sleeve can be reinforced.

[0016] The underwater pile foundation construction device is convenient for lifting equipment to lift it to the seabed to clamp the pile pipe, and can be constructed in deep water. The first hydraulic cylinder and the second hydraulic cylinder push the first semicircular clamping sleeve and the second semicircular clamping sleeve in parallel to clamp the pile pipe. The clamping is firm, and the auxiliary rod is fixed by inserting an iron column into the clamping groove, so that the closed first semicircular clamping sleeve and the second semicircular clamping sleeve can be reinforced.

The first connecting plate 22 connects the first base 1 and the second base 2 together, and the second connecting plate 12 connects the first side plate 3 and the second side plate 4 together.

[0026] Among them, triangular support plates 14 are welded between the first base 1 and the first side plate 3 and between the second base 2 and the second side plate 4. The triangular support plates 14 are used to improve the stability between the first base 1 and the first side plate 3, and between the second base 2 and the second side plate 4.

[0027] The sleeve 11 is connected to the limiting sleeve 9 , and one side of the auxiliary rod 10 is provided with slots 23 corresponding to the iron column 17 at equal distances. The slots 23 are provided to facilitate the insertion of one end of the iron column 17 .
