Description

Technical Field

[0001] The invention relates to a barge transport tool for large-diameter steel pipe piles. Background Art

[0002] As a common form of wind turbine foundation, large-diameter steel pipe pile foundation has many advantages such as simple structure, wide universality, convenient construction, short construction period, reliable performance, and high economic efficiency. Therefore, it is widely loved by owners and is one of the most commonly used wind turbine foundation forms in my country's offshore wind power industry.

[0003] However, with the rapid development of my country's wind power industry, new high-power wind turbines have emerged one after another, and the wind power industry has gradually moved from offshore to offshore, and the size of the steel pipe piles in the single pile foundation has gradually increased. Due to the different geological conditions of each wind farm, the designed steel pipe pile foundation has also produced various variable diameter models.

[0004] Most of the current transport tools for steel pipe piles are integrated steel structure tools. The curvature of the support surface in contact with the steel pipe pile is fixed and cannot be changed or adjusted, so the diameter of the steel pipe pile that can be adapted is single. Once the outer diameter of the steel pipe pile is larger than the inner diameter of the tool, there is a problem that the steel pipe pile cannot fall into the tool; if the outer diameter of the steel pipe pile is smaller than the inner diameter of the tool, there is a problem that the load is concentrated at the bottom of the tool, and the two sides of the tool cannot fit with the steel pipe pile. In order to prevent the steel pipe pile from shaking in the tool, it can only be simply padded with wooden wedges, and the stability of transportation is difficult to guarantee, so there are certain limitations and risks in use.

[0005] At the same time, since the supporting arc surface where the current transport tooling contacts the steel pipe piles is a steel structure, geotextiles are mostly used for protection between it and the steel pipe piles, and the protective effect is relatively low. During the lifting process of the steel pipe piles, the transport ship rises and falls due to load changes and waves, which can easily cause friction between the tooling and the steel pipe piles. Once the geotextile on the tooling falls off or slips, the tooling and the steel pipe piles will collide head-on, causing wear on the anti-corrosion layer of the steel pipe piles, increasing the difficulty of protecting the finished product and eliminating foundation defects. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide a large-diameter steel pipe pile drop and transportation tooling, which can fully cover the transportation of single wind farm steel pipe piles and multi-wind farm steel pipe piles and can achieve high-strength protection for the steel pipe piles.

[0032] The outer tension spring 33 is connected between the outer portion of the outer support plate 321 and the middle portion of the outer connection plate 314. The outer tension spring 33 can be used to adjust the posture of the outer support plate 32.

[0033] The barge transport tooling for large-diameter steel pipe piles of the present invention realizes the adjustment function through the movable inner diagonal braces 312, movable outer diagonal braces 313 and outer support plates 32 on a pair of outer brackets 3 and the inner support plates 22 on a pair of inner brackets 2. The movable inner diagonal braces 312 and movable outer diagonal braces 313 can be adjusted within an angle of 60° to 120° with the bottom plate 1, and the diameter can be changed by adjusting the movable inner diagonal braces 312 and movable outer diagonal braces 313 to close inward or expand outward. The barge transport tooling after the diameter change can be adapted to steel pipe piles with an outer diameter of 9 to 12m.

[0034] In the barge transport tooling of the present invention, the length of the bottom plate 1 is 11.5m; the spacing between the fixed middle columns 211 of the pair of inner brackets 2 is 3.85m, and the height of the fixed middle column 211 is 1.265m; the spacing between the movable middle columns 310 of the pair of outer brackets 3 is 8.7m; the height of the movable column 310 is 2.95m; the barge transport tooling of the present invention is divided into three working conditions when in use: inner use, suitable for steel pipe piles with an outer diameter of 9 to 10m; conventional use, suitable for steel pipe piles with an outer diameter of 10 to 11m (see Figure 6 ); for external expansion, suitable for steel pipe piles with an outer diameter of 11 to 12 m (see Figure 7 ).

[0035] When the barge transport tooling of the present invention is used for internal closure and external expansion, the limiting plates 311b on the two side walls of the movable column 310 are first removed, and then the movable inner diagonal brace 312 and the movable outer diagonal brace 313 are opened to make the movable column 311 in a free state; then the movable column 310 is adjusted to a suitable position, and the upper ends of the movable inner diagonal brace 312 and the upper ends of the movable outer diagonal brace 313 are inserted into the slots 311a on the inner and outer walls of the movable column 310 one by one, and then the two limiting plates 311 are inserted into the limiting grooves 311b on the inner and outer walls of the movable column 310 that are closest to the upper ends of the movable inner diagonal brace 312 and the upper ends of the movable outer diagonal brace 313 one by one, and after confirming that the movable inner diagonal brace 312 and the movable outer diagonal brace 313 are firmly installed, the barge transport tooling can be put into use.

[0036] The inner support plate 22 and the outer support plate 32 are also movable. The inner support plate 22 is hinged to the fixed middle column 211 through a pin, and the outer support plate 32 is hinged to the movable middle column 310 through a pin. When the barge transport tooling of the present invention is in a state of being ready for use, the inner support plate 22 is pulled by the inner tension spring 23, and the outer support plate 32 is pulled by the outer tension spring 33. Generally, the opening is slightly upward; during the mooring process of the steel pipe pile 100, the lower edges of the inner support plate 22 and the outer support plate 32 first contact the steel pipe pile 100, and then as the steel pipe pile 100 is lowered, the opening of the inner support plate 22 and the opening of the outer support plate 32 slowly snap inward under the pressure of the steel pipe pile 100 until they are completely in close contact with the steel pipe pile 100. This design can adapt to the outer diameter arc of different steel pipe piles 100, enhance the fit between the barge transport tooling and the steel pipe pile 100, and make the load distribution more uniform, providing sufficient protection and fixing effects.

[0037] In the barge transportation tooling for large-diameter steel pipe piles of the present invention, if the movable inner diagonal brace 312 and the movable outer diagonal brace 313 of a pair of outer brackets 3 are replaced by hydraulic cylinders, automatic adjustment can be achieved, reducing the workload of workers and at the same time making the outer bracket 32 ​​fit the steel pipe pile 100 more perfectly. In this way, there is no need to open the slot 311a and the limit slot 311b on the inner and outer side walls of the movable middle column 310, and the limit plate 311 is also eliminated.

[0038] The protective function of the barge transport tooling for large-diameter steel pipe piles of the present invention is mainly realized by the replaceable polyurethane pads on the top surface of the inner support plate 22 and the top surface of the outer support plate 32. The polyurethane pads have the characteristics of good wear resistance, high strength, high elasticity, good cushioning, good oil resistance and chemical resistance, high friction coefficient, low temperature resistance, ozone resistance, radiation resistance, electrical insulation, good bonding performance, etc.; they can provide extremely good protection for steel pipe piles, greatly reduce the vibration of steel pipe piles, provide good buffering protection for steel pipe piles, and greatly improve the safety during transportation; at the same time, the polyurethane pads themselves do not need to be frequently replaced and maintained, which greatly reduces the work content, reduces labor costs, and avoids the occurrence of geotextiles that are not firmly fixed, slipped, and inadequately protected due to work errors of workers.

[0039] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those skilled in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
