Description

Technical Field

[0001] This utility model belongs to the field of steel pipe pile construction technology, and in particular relates to an auxiliary device for steel pipe pile construction. Background Technology

[0002] The axial direction of the top flange of the offshore wind turbine foundation pile must be consistent with the direction of the bottom tower entrance; that is, the axial direction of the steel pipe pile must meet the design requirements. This requirement is crucial to ensuring the structural stability and operational safety of the offshore wind turbine. According to the welding specifications for steel pipe piles, accurate control of the axial direction not only affects the connection quality between the foundation pile and the tower, but also directly impacts the stress distribution and seismic performance of the entire wind turbine generator set. During the welding process, the axial position deviation of the steel pipe pile must be strictly controlled within the specified range to ensure the uniformity and strength of the weld. Any deviation in the axial direction may lead to stress concentration in the weld, reducing the reliability of the welded joint, and even causing structural damage during long-term operation.

[0003] Currently, after the crane lifts and erects the steel pipe piles, the complex marine environment makes it difficult to easily adjust the axial position of the piles. This leads to difficulties in aligning the piles with the base or lower pile during hoisting, and even after alignment, misalignment is likely to occur. This problem not only affects the construction progress but also poses a potential threat to the welding quality of the steel pipe piles, impacting their structural strength and stability.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] An auxiliary device for steel pipe pile construction, such as Figures 1 to 3As shown, the assembly includes a composite body with at least three guide mechanisms evenly arranged circumferentially. The composite body includes a first clamping member 1 and a second clamping member 2, which are connected by connecting bolts 3 and have a clamping gap between them. The guide mechanism includes a support 4 and a guide member 6. The guide member 6 is slidably mounted on the support 4. The support 4 has an assembly groove 8 for assembling the guide member 6 on one side facing the composite body, and an adjustment component for pushing the guide member 6 towards the composite body on the other side. The composite body has an opening at the position corresponding to the assembly groove 8 to facilitate the passage of the guide member 6.

[0029] For example, the guide mechanism can be evenly arranged in three, four or more parts. The first clamping member 1 and the second clamping member 2 are connected by at least two connecting bolts 3 corresponding to each other on the left and right sides to ensure that the first clamping member 1 and the second clamping member 2 can continuously and stably clamp the lower steel pipe pile or base. Both the first clamping member 1 and the second clamping member 2 are provided with bolt holes for installing the connecting bolts 3, and both the first clamping member 1 and the second clamping member 2 are fixed with supports 4.

[0030] In practical applications, the assembly can be installed and fixed on the lower steel pipe pile or base. When hoisting the upper steel pipe pile, the guide mechanism on the assembly can be used to conveniently guide the two steel pipe piles to be aligned. After alignment, the multiple guide mechanisms evenly set can also play a good limiting role for the steel pipe piles, preventing the two steel pipe piles from being misaligned. This is conducive to improving the welding quality of the subsequent steel pipe piles and reducing the welding difficulty for operators.

[0031] Preferably, the guide member 6 includes a vertical section and an arc-shaped section. The vertical section extends into the mounting groove 8 and is slidably mounted on the support 4. Exemplarily, an arc-shaped plate 15 is provided on the side of the arc-shaped section facing the assembly. The arc-shaped plate 15 and the arc-shaped section are arranged in a T-shape, with one end of the arc-shaped plate 15 abutting against the support 4. The arc-shaped plate 15 can be fixed to the guide member 6 by conventional methods such as welding.

[0032] In practical applications, the T-shaped guide member 6 and the arc-shaped plate 15 have higher structural strength, and the arc-shaped plate 15 can effectively guide the end of the upper steel pipe pile. Multiple arc-shaped plates 15 on the guide mechanism can form a trumpet-shaped opening. As the steel pipe pile descends, the multiple arc-shaped plates 15 can guide the upper steel pipe pile to gradually align with the lower steel pipe pile. Furthermore, by using the arc-shaped plate 15 to support the support 4, the force on the arc-shaped plate 15 can be distributed, preventing deformation and damage to the guide member 6 and the arc-shaped plate 15. This ensures that the arc-shaped plate 15 and the guide member 6 can continuously and stably guide and limit the steel pipe pile.

[0033] Preferably, the end of the arc-shaped plate 15 facing the support 4 is provided with a bent portion 16 for supporting the support 4. By providing the bent portion 16, it is beneficial to increase the contact area between the arc-shaped plate 15 and the support 4, avoid stress concentration, and further reduce the probability of the arc-shaped plate 15 deforming or bending.

[0034] In practical applications, the arc-shaped plate 15 is connected to the arc-shaped segment by reinforcing plates 14, with multiple reinforcing plates 14 spaced apart along the length of the arc-shaped segment. For example, two or more reinforcing plates 14 can be spaced apart, and the reinforcing plates 14 and the arc-shaped plate 15, as well as the reinforcing plates 14 and the arc-shaped segment, can be connected by conventional methods such as welding. By spaced out multiple reinforcing plates 14, the structural strength of the guide member 6 and the arc-shaped plate 15 is further improved, ensuring the reliability of the arc-shaped plate 15 when guiding the steel pipe pile downwards for alignment.

[0035] Preferably, the left and right sides of the guide member 6 are slidably mounted on the support 4 via sliders 11. Correspondingly, the left and right sides of the support 4 are provided with sliding grooves 10 that mate with the sliders 11, and the sliding grooves 10 communicate with the assembly groove 8. For example, the slider 11 is a rectangular block, and two sliders 11 and two sliding grooves 10 are provided. The slider 11 is fixed to the guide member 6, and the sliding groove 10 communicates with an opening on the assembly. By utilizing the cooperation of the slider 11 and the sliding groove 10, the guide member 6 can move stably on the support 4, allowing the operator to adjust the position of the guide member 6 on the support 4 as needed, so that the guide member 6 can better guide and limit the steel pipe pile.

[0036] Preferably, the adjustment assembly includes an adjustment bolt 7, and the support 4 has a threaded hole 13 that mates with the adjustment bolt 7. One end of the adjustment bolt 7 passes through the threaded hole 13 and abuts against the guide member 6, while the other end has a handle member 17. Exemplarily, the threaded hole 13 communicates with the mounting groove 8, and the handle member 17 is fixed to the adjustment bolt 7.

[0037] In practical applications, the guide member 6 is provided with a positioning groove 12 that mates with the adjusting bolt 7, and the inner diameter of the positioning groove 12 is larger than the diameter of the adjusting bolt 7. By utilizing the positioning groove 12 on the guide member 6 and the adjusting bolt 7, the operator can move the guide member 6 by turning the adjusting bolt 7, thereby achieving fine adjustment of the position of the guide member 6. This allows the guide members 6 on multiple guiding mechanisms to further clamp and limit the end of the steel pipe pile, preventing the end of the steel pipe pile from moving during welding, thus ensuring the welding accuracy and quality of the steel pipe pile. In addition, the positioning groove 12 and the threaded hole 13 provide two-point limiting for the adjusting bolt 7, which helps improve the stability of the adjusting bolt 7 and prevents deformation of the adjusting bolt 7.

[0038] Preferably, both the left and right sides of the support 4 are connected to the assembly via connecting plates 5. For example, two, four, or more connecting plates 5 can be provided on the left and right sides of the support 4. The connecting plates 5 can be fixed to the support 4 and to the assembly using conventional methods such as welding. By providing connecting plates 5, the structural strength at the connection between the support 4 and the assembly is improved, ensuring that the support 4 can continuously and stably limit the guide member 6 and the arc-shaped plate 15. Furthermore, the support 4 and the first clamping member 1 or the second clamping member 2 can also be integrally formed to ensure the stability of the support 4 on the assembly.

[0039] Preferably, the assembly also includes a connector 9 for connecting the support rod. For example, one end of the connector 9 is fixed to the assembly, and the other end has a mounting hole. The connector 9 can also have a groove that mates with the assembly. By providing the connector 9, the operator can also bolt one end of the support rod to the connector 9 and fix the other end of the support rod to a fixed position such as a work platform. This supports and fixes the assembly, further improving the stability of the assembly on the lower steel pipe pile and ensuring that the guiding mechanism on the assembly can stably guide and limit the movement of the upper steel pipe pile.

[0040] The auxiliary equipment for steel pipe pile construction described in this utility model can be used for the hoisting and welding of steel pipe piles. It has the advantages of simple structure, good stability, and easy installation and use. It can guide the steel pipe pile to achieve rapid alignment during hoisting and can effectively prevent the steel pipe pile from shifting during hoisting and welding, which is conducive to improving the welding quality and construction efficiency of the steel pipe pile.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
