Description

Technical Field

[0001] This utility model relates to the field of offshore photovoltaic construction technology, and in particular to a transport tool for offshore steel pipe piles. Background Technology

[0002] Steel pipe piles are widely used in construction engineering due to their advantages such as high load-bearing capacity, convenient construction, and strong adaptability. Offshore engineering foundations often utilize steel pipe piles, and some structures use small to medium-sized steel pipe piles as pile group foundations, such as offshore wind turbine jacket foundations, pier foundations, and offshore photovoltaic foundations. During construction, small to medium-sized steel pipe piles need to be stacked in multiple layers on transport barges to improve transportation efficiency and reduce transportation costs.

[0003] Currently, the stacking and transportation of steel pipe piles at sea mostly uses short-section wooden supports. Before stacking each layer of steel pipe piles, wooden supports are placed under the piles to be stacked, and then the piles are lifted and stacked. This method has several problems: 1) The short-section wooden supports have poor stability, leading to the possibility of the steel pipe piles shifting or falling after being lifted and stacked, causing direct contact between the piles and damaging the surface anti-corrosion coating; 2) According to specifications, each layer of support structure has deviation requirements, resulting in low efficiency of manual stacking, increasing the operating time of ship machinery, and indirectly increasing the operating cost of ship machinery; 3) Due to the high cost of steel pipe piles, small steel pipe piles in offshore engineering often use variable-diameter steel pipe piles, i.e., a structure with a larger bottom diameter and a smaller top diameter. However, the smaller diameter portion of this type of steel pipe pile is suspended in the air, making effective support difficult.

[0004] Therefore, it is necessary to design a new type of offshore steel pipe pile transportation tool that is not only easy to install and disassemble, but also applicable to different diameters, especially for effectively supporting the stacking of variable diameter steel pipe piles. Utility Model Content

[0005] The purpose of this utility model is to provide a marine steel pipe pile transportation tool that solves the above-mentioned technical problems.

[0006] Therefore, the technical solution of this utility model is as follows:

[0007] A transport fixture for offshore steel pipe piles includes two fixture columns, multiple pairs of layered support legs, a bottom support pad, and multiple upper support pads. The bottom support pad is a horizontally positioned strip beam with multiple identical arc-shaped grooves evenly spaced along its length on its top surface. The radius of each arc-shaped groove is adapted to the pipe diameter of the corresponding side of the steel pipe pile to be supported. The two fixture columns are symmetrically arranged, with their bottom ends vertically fixed to both ends of the bottom support pad. Multiple pairs of layered support legs are spaced apart from bottom to top on the opposite sidewalls of the two fixture columns, with each pair of layered support legs being symmetrically arranged. Multiple high-rise supports are horizontally arranged on multiple pairs of layered support legs, one to one. Each high-rise support includes a horizontally arranged strip beam with multiple arc-shaped through slots evenly spaced along its length on its top and bottom surfaces. The radius of the arc-shaped through slots is the same as the radius of the arc-shaped through slots on the bottom support. The two end faces of the beam extend outward along the horizontal direction and form connecting ear plates. The high-rise supports are pressed and fixed to the top side of the corresponding pair of layered support legs by the two connecting ear plates, and the arc-shaped through slots on the bottom support and each high-rise support are arranged vertically in correspondence.

[0008] Furthermore, the length of the bottom support is adapted to the width of the barge, allowing it to be installed along the width of the barge and fixed to the deck via the bottom surface.

[0009] Furthermore, the height of the tooling column is adapted to the diameter of the steel pipe pile and the number of stacking layers.

[0010] Furthermore, two column braces are symmetrically arranged on both sides of the two tooling columns. Each column brace is obliquely arranged on the outside of the tooling column, with its top end fixed to the side wall of the tooling column and its bottom end fixed to the deck of the barge.

[0011] Furthermore, the layered support leg is composed of a horizontal plate and an inclined plate; wherein, the inclined plate is obliquely arranged below the horizontal plate, and its top end is fixed to the bottom surface of one side of the horizontal plate, while the other side of the horizontal plate and the bottom end of the inclined plate are fixed to the side wall of the adjacent tooling column.

[0012] Furthermore, a first insertion hole is provided on the surface of the horizontal plate, and correspondingly, a second insertion hole is provided on the connecting ear plate that can communicate with the first insertion hole, so that the two ends of the high-rise support pad are respectively fixed to the corresponding pair of layered support legs by pins that are sequentially inserted into the second insertion hole on the connecting ear plate and the first insertion hole on the horizontal plate.

[0013] Furthermore, the spacing between two adjacent supports is adapted to the pipe diameter of the corresponding side of the steel pipe pile to be supported and the groove depth of the arc-shaped through groove, so that the upper and lower sides of the steel pipe pile located between the two supports are respectively embedded and pressed and fixed in the arc-shaped through groove of the two supports.

[0014] Furthermore, support lugs are symmetrically installed on the side walls at both ends of each high-rise support beam.

[0015] Compared with existing technologies, this offshore steel pipe pile transportation tool can realize multi-layer stacking of batch steel pipe piles on barges. It not only has good integrity and stability, but also can be adapted to different diameters in terms of structure. It is especially suitable for the customization and adjustment of variable diameter steel pipe piles, which can greatly improve the efficiency of offshore steel pipe pile barge transportation, maximize the utilization of barge load capacity, effectively reduce construction costs, and has good market application and promotion prospects.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention.

[0026] See Figure 1 The offshore steel pipe pile transport fixture 2 is used to fix the steel pipe piles 3 on the deck of the barge 1 to achieve maximum one-time batch transport of steel pipe piles 3 and maximize the utilization of the barge 1's transport capacity. In this embodiment, based on the length of the barge 1, it can stack a maximum of two sets of steel pipe piles 3. Therefore, four offshore steel pipe pile transport fixtures 2 are arranged on the barge 1 at intervals along the length of the barge 1; wherein, every two offshore steel pipe pile transport fixtures 2 form a set and are used for stacking a set of steel pipe piles 3.

[0027] See Figures 2-5 The offshore steel pipe pile transport frame includes a pair of tooling columns 4, two pairs of layered legs, a bottom support 8, and two upper supports; among them, the two pairs of layered legs are a pair of middle layer legs 6 and a pair of upper layer legs 7, and the two upper supports are a middle layer support 9 and an upper layer support 10.

[0028] The bottom support 8 is a strip beam, the length of which is less than the width of the barge 1. It is centered along the width of the barge 1 and welded and fixed at a designated position on the deck of the barge 1. The top surface of the beam has twelve identical arc-shaped through slots at equal intervals along its length. The radius of each arc-shaped through slot is adapted to the pipe diameter of the corresponding side of the steel pipe pile 3 to be supported, so that the corresponding side of the steel pipe pile 3 to be supported can be embedded and assembled in the arc-shaped through slot.

[0029] Two tooling columns 4 are symmetrically arranged at both ends of the bottom support 8. Specifically, the bottom end of each tooling column 4 is vertically welded and fixed to the two ends of the bottom support 8.

[0030] In this embodiment, based on the barge 1's transport capacity, each offshore steel pipe pile transport frame is designed to stack three layers of steel pipe piles 3. Therefore, the height of each tooling column 4 matches the overall height after stacking three layers of steel pipe piles 3.

[0031] As a preferred technical solution of this embodiment, column bracing 5 is symmetrically arranged on the outside of the two tooling columns 4. Each column bracing 5 is obliquely arranged on the outside of the tooling column 4, with its top end welded and fixed to the outer wall of the tooling column 4 and its bottom end welded and fixed to the deck of the barge 1.

[0032] Two intermediate support legs 6 are spaced apart above the bottom support pad 8 and symmetrically arranged on the opposite side walls of the two tooling columns 4, forming a support platform for setting the intermediate support pad 9. Two upper support legs 7 are spaced apart above the two intermediate support legs 6 and symmetrically arranged on the opposite side walls of the two tooling columns 4, forming a support platform for setting the upper support pad 10. The intermediate support legs 6 and the upper support legs 7 have the same structure. In this embodiment, both the intermediate support legs 6 and the upper support legs 7 are composed of a horizontal plate and an inclined plate. The inclined plate is obliquely arranged below the horizontal plate, and its top end is fixed to one side of the bottom surface of the horizontal plate, so that both the intermediate support legs 6 and the upper support legs 7 are in the shape of the number 7. The same side ends of the horizontal plate and the inclined plate on the intermediate support legs 6 and the upper support legs 7 are respectively fixed to the side wall of the adjacent tooling column 4, and the other side of the horizontal plate and the bottom end of the inclined plate are fixed to the side wall of the adjacent tooling column 4. The first insertion hole is centrally located on the horizontal plate of the middle layer support leg 6 and the upper layer support leg 7.

[0033] The intermediate support 9 and the upper support 10 have the same structure, and their lengths are adapted to the spacing between the two tooling columns 4. Taking the intermediate support 9 as an example, it includes a horizontally arranged strip beam, and twelve arc-shaped through slots are evenly spaced along its length on the top and bottom surfaces of the beam. The radius of each arc-shaped through slot is the same as the radius of the arc-shaped through slot on the top surface of the bottom support 8, so as to adapt to the pipe diameter on one side of the steel pipe pile 3 to be supported. Connecting ear plates 11 extend outward in the horizontal direction on both ends of the beam, and the connecting ear plates 11 are longitudinally provided with a connection to the intermediate support. The second insertion hole on the horizontal plate of leg 6 is connected to the first insertion hole. Then, by inserting pins 13 sequentially through the second insertion hole and the first insertion hole, the two ends of the intermediate layer support 9 are respectively fixed on the two intermediate layer support legs 6, thereby fixing them between the two tooling columns 4. Furthermore, the twelve arc-shaped through slots opened on the bottom surface of the beam of the intermediate layer support 9 can correspond one-to-one with the twelve arc-shaped through slots opened on the top surface of the beam of the bottom layer support 8, and the twelve arc-shaped through slots opened on the top surface of the beam of the intermediate layer support 9 can correspond one-to-one with the twelve arc-shaped through slots opened on the bottom surface of the beam of the upper layer support 10, so as to be respectively embedded and assembled on the two side walls of the steel pipe pile.

[0034] The positions of the intermediate support 9 and the upper support 10 between the two tooling columns 4 are determined by the positions of the intermediate support leg 6 and the upper support leg 7 on the two tooling columns 4, respectively, and are adapted to the pipe diameter of the corresponding side of the steel pipe pile 3 to be supported. This allows the arc-shaped grooves on the bottom surface of the intermediate support 9 to fit into the arc-shaped grooves of the steel pipe pile 3 supported in the bottom support 8, and to press tightly against the outer wall of the steel pipe pile 3, thereby fixing one side of the steel pipe pile 3 and preventing the steel pipe pile 3 from rolling or shaking during transportation.

[0035] As a preferred technical solution in this embodiment, two support lugs 12 are symmetrically placed on the side walls at both ends of the beam of the intermediate support 9 and the upper support 10 to facilitate the hoisting and installation of the two.

[0036] In this implementation, since the steel pipe piles 3 to be transported in batches are variable diameter steel pipe piles, the dimensions of the two offshore steel pipe pile transport fixtures 2 located on both sides of the variable diameter steel pipe piles are customized according to their diameters at the support positions of the variable diameter steel pipe piles. Specifically, the beam heights of the bottom support 8, the middle support 9, and the upper support 10 of the offshore steel pipe pile transport frame located on the smaller diameter side are greater than the beam heights of the bottom support 8, the middle support 9, and the upper support 10 of the offshore steel pipe pile transport frame located on the larger diameter side. The difference between the beam heights of the two sides is equal to the radius difference between the smaller diameter side and the larger diameter side, so that the variable diameter steel pipe piles can be set horizontally on each layer of support.

[0037] See Figure 1 , Figures 6-9 The specific implementation steps of the bulk barge transport method for steel pipe piles using the marine steel pipe pile transport tool 2 are as follows:

[0038] S1. Based on the length of the steel pipe piles 3 to be transported, determine the placement positions of the four offshore steel pipe pile transport fixtures 2 on the barge 1, so that the two offshore steel pipe pile transport fixtures 2 on the front side of the barge 1 are used for the batch transport of a group of steel pipe piles 3, and the two offshore steel pipe pile transport fixtures 2 on the rear side of the barge 1 are used for the batch transport of another group of steel pipe piles 3; wherein, the bottom support 8 in each offshore steel pipe pile transport fixture 2 is welded and fixed to the deck along the width direction of the barge 1, and the fixture column 4, column brace 5, two intermediate support legs 6 and two upper support legs 7 are welded and fixed in sequence based on the bottom support 8;

[0039] S2. Stack and secure the first batch of steel pipe piles to the two offshore steel pipe pile transport fixtures 2 on the front side of barge 1. The specific steps are as follows:

[0040] S201. The steel pipe piles 3 are lifted in sequence and transported to the two bottom support pads 8. Each pair corresponds to one of the arc-shaped grooves along the length of the barge 1 and is set horizontally until the two bottom support pads 8 are filled with steel pipe piles 3 side by side.

[0041] S202. Using the support lugs 12 at both ends of the intermediate layer support 9, the intermediate layer support 9 is hoisted onto the intermediate layer support leg 6 between the two tooling columns 4. The connecting lugs at both ends are pressed onto the top surfaces of the two intermediate layer support legs 6 respectively, and are temporarily fixed by the pins 13 that are sequentially inserted into the connecting lugs and the intermediate support legs 6. At this time, the intermediate layer support 9 is pressed onto the side walls of each steel pipe pile below.

[0042] S203. The steel pipe piles 3 are lifted in sequence and transported to the two intermediate layer support pads 8. Each pair corresponds to one of the arc-shaped grooves along the length of the barge 1 and is set horizontally until the two intermediate layer support pads 8 are filled with steel pipe piles 3 side by side.

[0043] S204. Using steps S3 and S4, complete the installation of the upper support 10 and the parallel laying of the steel pipe piles 3 on it.

[0044] S3. Using the same method as step S2, complete the stacking and fixing of the second batch of steel pipe piles to the two marine steel pipe pile transport fixtures 2 on the rear side of barge 1.

[0045] S4. After the steel pipe piles are transported to the construction site in batches by barge, the steel pipe piles 3 are lifted from top to bottom by crane or pile driving equipment and the pile driving construction is completed. After the steel pipe piles 3 stacked on each layer are lifted and the corresponding pile driving construction is completed, the pin 13 used to connect the high-level support and the layer support legs is pulled out, so that the crane can lift the high-level support and lift and construct the steel pipe piles 3 stacked on the next layer.
