Description

Technical Field

[0001] The utility model relates to the installation construction of an offshore wind power foundation construction platform, in particular to a hanging device for an offshore wind power foundation construction platform. Background Art

[0002] After the installation of the offshore wind power foundation construction platform is completed, in order to ensure stability and bearing capacity, it is necessary to connect and hang the foundation construction platform to the support pile. The commonly used hanging device at present is to connect the foundation construction platform to the support pile with steel wire ropes or turnbuckles. The connection length of this scheme is not adjustable, the construction is inconvenient, and the construction platform is heavy, making the hanging difficult.

[0003] Due to the short construction period and high construction accuracy requirements of offshore wind power. Therefore, it is particularly important to invent a safe, reliable, practical and simple hanging device. Summary of the Invention

[0004] The purpose of the utility model is to provide a hanging device for an offshore wind power foundation construction platform, which can ensure that the foundation construction platform is smoothly and quickly hung and fixed on the support pile, and ensure the stability and bearing capacity of the foundation construction platform.

[0005] The purpose of the utility model is realized as follows:

[0006] A hanging device for an offshore wind power foundation construction platform, characterized in that: it is composed of four sets of exactly the same sub-hanging devices. The four sets of sub-hanging devices are respectively installed at the four corners of the foundation construction platform. Each set of sub-hanging devices includes a hoop, a rubber pad, a suspension anchor box, a steel bar, a nut and an anchor backing plate, a high-strength bolt, and a steel wedge. A circular steel pipe column is vertically arranged at the edge of the foundation construction platform that is lowered in place and horizontally placed. A circular support pile is vertically inserted inside the steel pipe column. The suspension anchor box is welded above the foundation construction platform and at the upper end of the steel pipe column, so that the suspension anchor box and the foundation construction platform become an integral whole. The lower ends of two steel bars outside the steel pipe column are radially and vertically inserted into the suspension anchor box. Two rows of uniformly distributed round holes are provided on the wing plates at both ends of each semi-circular hoop. Above the two steel pipe columns and at the upper ends of the two steel bars, two semi-circular hoops tightly clamp the two steel bars. Then, after passing the high-strength bolts through the round holes on the wing plates of the two hoops and together with the nuts, the two hoops are fixed together and tightly hold the support pile, so that the hoop is tightly held and fixed on the support pile. Nuts and anchor backing plates screwed onto the steel bars are used to fix both the upper surface of the hoop and the two ends of the suspension anchor box. 4 steel wedges symmetrically distributed at 4×90° are evenly filled in the gap between the top of the steel pipe column of the foundation construction platform and the middle part of the support pile.

[0007] A rubber pad is provided between the inner wall of the hoop and the support pile.

[0008] On the inner side of each wing plate of the hoop, there are two clamping plates perpendicular to the wing plate. The distance between the two clamping plates is slightly larger than the diameter of a steel pipe column, and the two clamping plates can center the plane of the steel pipe column in the middle.

[0009] The utility model has the following advantages:

[0010] 1. After the support pile is driven into place, the foundation construction platform and the support pile are connected through the utility model, and the foundation construction platform is fixed on the support pile, enabling the foundation construction platform to meet the operation requirements under various complex geological conditions.

[0012] 3. After the first installation is completed, during the subsequent transfer of the foundation construction platform, the support pile can be quickly fixed on the foundation construction platform through the utility model, greatly simplifying the entire transfer procedure of the foundation construction platform and effectively improving the transfer efficiency of the foundation construction platform;

[0013] 4. The installation height of the hoop can be adjusted according to actual needs;

[0014] 5. Under various complex geological conditions, through different driving depths of the support pile, the bearing capacity of the support pile can meet the operation requirements of the foundation construction platform;

[0015] 6.

[0025] The patent of the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] A hanging device for an offshore wind power foundation construction platform is composed of four identical sub-hanging devices. The four sub-hanging devices are respectively installed at the four corners of the foundation construction platform 10. Each sub-hanging device includes a holding hoop 1, a rubber pad 2, a suspension anchor box 3, a steel bar 4, a nut and an anchor backing plate 5, a high-strength bolt 6, and a steel wedge 7. A circular steel pipe column 9 is vertically provided at the edge of the foundation construction platform 10 that is lowered in place and horizontally placed. A circular support pile 8 is vertically driven inside the steel pipe column 9; the suspension anchor box 3 is welded above the foundation construction platform 10 and at the upper end of the steel pipe column 9, making the suspension anchor box 3 and the foundation construction platform 10 an integral whole, which can more effectively transfer the load; the lower ends of two steel bars 4 outside the steel pipe column 9 are radially and vertically inserted into the suspension anchor box 3. Two rows of uniformly arranged round holes 11 are provided on the wing plates 12 at both ends of each semi-circular holding hoop 1. Above the two steel pipe columns 9 and at the upper ends of the two steel bars 4, two semi-circular holding hoops 1 tightly clamp the two steel bars 4. Then, after passing the high-strength bolts 6 through the round holes 11 on the wing plates 12 of the two holding hoops 1, together with the nuts, the two holding hoops 1 are fixed together and tightly hold the support pile 8, so that the holding hoop 1 is tightly held and fixed on the support pile 8, and the foundation construction platform 10 and the support pile 8 are connected through the steel bar 4; nuts and anchor backing plates 5 screwed onto the steel bar 4 are used at the top of the holding hoop 1 and at both ends of the suspension anchor box 3 to keep the whole hanging device in a stable state; steel wedges 7 symmetrically distributed at 4×90° are uniformly filled in the gap between the top of the steel pipe column 9 of the foundation construction platform 10 and the middle of the support pile 8, which can effectively reduce the platform shaking.

[0027] A rubber pad 2 is provided between the inner wall of the holding hoop 1 and the support pile 8 to increase the friction between the holding hoop 1 and the support pile 8.

[0028] On the inner side of each wing plate 12 of the holding hoop 1, two clamping plates 13 perpendicular to the wing plate 12 are provided. The distance between the two clamping plates 13 is slightly larger than the diameter of a steel pipe column 9. The two clamping plates 13 can hold the steel pipe column 9 in the middle and prevent the steel pipe column 9 from shaking.

[0029] Working principle: At a corner of the foundation construction platform 10, weld the suspension anchor box 3 of a set of sub-suspension devices to the upper end of the steel pipe column 9, so that the suspension anchor box 3 and the foundation construction platform 10 become an integral whole, transfer the load of the foundation construction platform 10 to the suspension anchor box 3, and then transfer it to the steel bar 4 through the suspension anchor box 3 and the nuts and anchor backing plates 5 at the lowermost end. The steel bar 4 transfers the load to the two hoops 1 through the nuts and anchor backing plates 5 at the uppermost end, and the two hoops 1 transfer the load to the support piles 8 through friction, so as to keep the foundation construction platform 10 stable; finally, install the remaining three sets of sub-suspension devices at the remaining triangle of the foundation construction platform 10 to realize hanging the foundation construction platform 10 on the four support piles 8;
