Description

Technical Field

[0001] This utility model relates to the field of pile driving technology, specifically to a positioning device for driving and positioning marine steel pipe composite piles. Background Technology

[0002] Offshore piling is a core foundational construction technology in marine engineering. It mainly refers to the construction process of accurately inserting steel piles, concrete piles, and other piles into the seabed strata using specialized piling equipment. Its core purpose is to build a stable "underwater support" for offshore structures to resist external forces such as wind, waves, currents, tides, and ship collisions in the marine environment.

[0003] In existing technologies, the method of offshore piling is to use small vessels to carry piling equipment. That is, a small vessel equipped with a crane and a vibratory hammer is used. After the vessel is fixed in position by an anchor winch, the precast pile is hoisted into the pile hole guide positioning frame composed of a pair of arc-shaped rocker arms. The pile is first inserted into the seabed by its own weight, and then the vibratory hammer is started to press the pile into the design depth using vibration force.

[0004] Simply relying on a simple curved rocker arm positioning frame and anchor winch to fix the ship's position is prone to displacement under the influence of wind, waves and currents at sea. It is difficult to accurately control the verticality and planar position of the pile, which can easily lead to pile tilting and deviation, affecting the quality of the pile foundation project. The vibration hammer has limited excitation force, and the pile driving speed is slow for hard seabed soil. Moreover, the ship's position and pile positioning need to be adjusted frequently for each pile driving, resulting in low overall operation efficiency and inability to efficiently position the pile. To address the above problems, a marine steel pipe composite pile driving and positioning device is proposed. Utility Model Content

Secondly, the upper roller, through the adjustment of the threaded rod and slider, can adapt to steel pipe composite piles of different diameters, offering strong versatility and eliminating the need for separate equipment for different pile diameters, thus reducing equipment investment costs. Thirdly, the rolling contact design between the rollers and the pile reduces frictional resistance during driving, making pile driving smoother and indirectly accelerating the construction progress.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2This utility model discloses a marine steel pipe composite pile driving and positioning device, including a Bailey bridge 1. Steel columns 16 are fixedly connected to the top front end of the Bailey bridge 1, which can fix the position of a first protective rod 17. The inner wall of each steel column 16 is penetrated and fixedly connected to the first protective rod 17. Support columns 18 are fixedly connected to both sides of the top of the positioning frame 2. The support columns 18 are welded to the top of the positioning frame 2. Second protective rods 19 are penetrated and fixedly connected to the outer ring of each support column 18. The second protective rods 19 prevent workers on the platform 20 from falling from the positioning frame 2, thus protecting the workers. The platform 20 is fixedly connected to both sides of the middle top of the positioning frame 2, allowing workers to work or observe from the platform 20.

[0028] Reference Figure 2 - Figure 4 A positioning frame 2 is installed at the top center of the Bailey bridge 1. The positioning frame 2 is welded from multiple steel pipes and is placed above the Bailey bridge 1. Due to its own weight, the positioning frame 2 can prevent it from moving at the Bailey bridge 1. Depending on different needs, the positioning frame 2 can be welded or placed above the Bailey bridge 1 in different ways. The top of the inner wall of the positioning frame 2 is fixedly connected to an upper fixing plate 3. An upper frame 4 is fixedly connected to the top of the upper fixing plate 3, and the upper fixing plate 3 supports the position of the upper frame 4. A connecting plate 7 is fixedly connected to one end of the inner wall of the upper frame 4. A threaded rod 8 is threadedly connected to one end of the connecting plate 7. The connecting plate 7 fixes the position of the threaded rod 8 and has a nut pair inside. One end of the threaded rod 8 passes through and is rotatably connected to a first slider 5. The rotation of the threaded rod 8 drives the first slider 5 to move, and the first slider 5 is slidably connected to the inner wall of the upper frame 4. The inner wall of the upper frame 4 guides the movement of the first slider 5. An upper roller 6 is rotatably connected to the inner wall of the first slider 5. The upper roller 6 is combined with the steel pipe. When the piles come into contact, the friction of the steel pipe composite pile can be increased. A knob 9 is fixedly connected to the other end of the threaded rod 8, which facilitates the rotation of the threaded rod 8. A lower fixing plate 10 is fixedly connected to the bottom of the inner wall of the positioning frame 2. Limiting rods 12 are fixedly connected to both sides of the top of the lower fixing plate 10. The limiting rods 12 can limit the movement of the lower frame 11. The lower frame 11 is slidably connected through the middle of the top of the lower fixing plate 10. A third slider 14 is fixedly connected to the inner wall of the lower frame 11. The movement of the lower frame 11 drives the third slider 14 to move synchronously. A second slider 13 is fixedly connected to the bottom of the lower frame 11. The lower frame 11 can slide on the lower fixing plate 10 through the second slider 13. The second slider 13 is slidably connected to the top of the lower fixing plate 10. There is a limiting buckle mechanism between the second slider 13 and the lower fixing plate 10, which can limit the position of the lower frame 11. A lower roller 15 is rotatably connected to the inner wall of the third slider 14. The lower roller 15 can provide secondary guidance for the steel pipe composite pile.

[0029] Working principle: By rotating knob 9, the threaded rod 8 is rotated. Due to the fixed nut pair built into the connecting plate 7, the threaded rod 8 moves axially when rotating, thereby pushing the first slider 5 to slide along the inner wall of the upper frame 4. Finally, the position of the upper roller 6 is adjusted to a limit state that matches the diameter of the steel pipe composite pile, achieving initial limitation of the upper part of the pile. The adjustment of the lower roller 15 pushes the lower frame 11, causing it to drive the second slider 13 to slide along the lower fixed plate 10. The limiting rod 12 guides the movement direction of the lower frame 11 to prevent deviation. At the same time, the movement of the lower frame 11 drives the third slider 14 to move synchronously, so that the lower roller 15... The position corresponds to the upper roller 6, completing the guiding and limiting of the lower part of the pile. The limiting and buckling mechanism between the lower fixed plate 10 and the second slider 13, such as existing structures like springs and buckles, can fix the position of the lower frame 11. The steel pipe composite pile is hoisted into the positioning frame 2, passing between the upper roller 6 and the lower roller 15. The upper roller 6 contacts the pile and, through the rotational characteristics of the roller, radially limits the pile and prevents it from shifting left or right. It also provides guidance during the pile driving process, reducing frictional resistance. The lower roller 15 provides secondary guidance to the lower part of the pile, preventing the pile from tilting during driving and ensuring that the pile is driven vertically.
