Technical Field
[0001] This utility model relates to the field of pile foundation construction equipment technology, specifically a combined pile foundation operation platform. Background Technology
[0002] In water-based engineering projects such as cross-sea bridges, offshore wind power foundations, and port terminals, the combined pile foundation operation platform is the core supporting equipment for the installation, connection, and anti-corrosion treatment of steel pipe piles.
[0003] Currently, the efficiency of platform construction in marine or water environments directly affects the construction cycle of projects. Existing platforms are mostly modular steel components, which need to be hoisted and positioned piece by piece using water-based lifting equipment. Affected by water flow and waves, it is difficult to control the precision of component splicing, the bolt tightening process is cumbersome, and the assembly is time-consuming and labor-intensive, which seriously restricts the construction progress of marine projects and makes the platform construction efficiency low. To address this, we propose a combined pile foundation operation platform. Utility Model Content
[0004] The purpose of this utility model is to provide a combined pile foundation operation platform, which has the advantages of high construction efficiency and convenient operation. It solves the problems of existing platforms, which are mostly split steel components, requiring one-by-one hoisting and positioning by water-based lifting equipment. The components are affected by water flow and waves, making it difficult to control the accuracy of component splicing. The bolt tightening process is cumbersome, and the assembly is time-consuming and labor-intensive, which seriously restricts the construction progress of water-based projects and makes the platform construction efficiency low.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined pile foundation working platform, comprising:
[0006] Floats, connecting rods, and vertical pipes;
[0007] The outer surface of the pontoon is provided with arc-shaped protrusions and matching arc grooves. Connecting ears are provided at the four corners of the outer surface of the pontoon, and through holes are opened on the inner surface of one end of the connecting ears. Docking recesses are provided at the four corners of the top of the pontoon.
[0008] The connecting rod is inserted into the through hole of the connecting ear, the upper end of the connecting rod is threaded with a connecting seat, and a rotating bar is provided in the groove at the bottom of the connecting rod.
[0009] The vertical tube is inserted into the inner side of the docking recess, and a connecting sleeve is installed on the outer surface of the vertical tube. The vertical tube is connected to the railing tube through the connecting sleeve.
[0010] Preferably, the pontoon has a hollow structure and is made of strong and tough high molecular weight polyethylene material.
[0011] Preferably, the arc-shaped protrusion and the mating arc groove are positioned correspondingly, and the arc-shaped protrusion and the mating arc groove are adapted to each other.
[0012] Preferably, the four connecting lugs on the outer surface of the float are all at different heights, and the height difference between two adjacent connecting lugs is equal to the thickness of the connecting lug itself in the counterclockwise direction.
[0013] Preferably, a positioning post is provided on the inner side of the docking recess, and the positioning post is adapted to the inner wall of the vertical tube.
[0014] Preferably, the upper and lower corners of the float are provided with arc-shaped positioning notches, and the arc-shaped positioning notches are adapted to the outer surfaces of the connecting seat and the lower end of the connecting rod, and the top of the connecting seat is provided with an anti-slip groove.
[0015] Preferably, the top of the pontoon is provided with anti-slip texture.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model utilizes the guiding effect of the arc-shaped protrusions around the pontoons and the matching arc grooves, as well as the design of connecting ears with preset height differences at the four corners. When multiple pontoons approach each other, they can automatically align. The connecting rod can pass through all the stacked and aligned connecting ears at once, and achieve quick locking through the threaded connection between the bottom rotating bar and the top connecting seat. This modular connection method of one-rod through and one-click locking completely eliminates the cumbersome hoisting and alignment and high-altitude bolt tightening operations of traditional platforms, greatly reducing the construction time on water and the dependence on large lifting equipment, and improving the construction efficiency many times over.
[0018] 2. The connection between the pontoons in this utility model is formed by multiple sets of connecting rods to form a rigid frame in three-dimensional space. Combined with the interlocking of the arc-shaped protrusions and the matching arc grooves, the horizontal displacement and vertical separation between the pontoons are effectively restricted. Secondly, the connecting ears adopt a highly staggered stacking design, which makes the contact area between the connecting rod and each connecting ear larger when passing through, and the force is more even, avoiding stress concentration. This greatly improves the connection strength and overall stability of the entire platform module, enabling it to better resist the impact of water flow and waves.
[0019] 3. This utility model provides precise positioning and stable support for the insertion of the vertical pipe through the docking recess at the top of the pontoon. Through the connecting sleeve, safety protection facilities such as guardrails can be quickly installed on the vertical pipe to form a complete working platform system. This design allows the platform to be easily expanded laterally like building blocks according to project needs, while ensuring the rapid deployment of safety structures such as guardrails. It is highly adaptable, and the pontoon is made of strong and tough high-molecular polyethylene material, which has high strength, corrosion resistance and durability. Attached Figure Description

[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] The components of this application, including the float 1, arc-shaped positioning notch 101, anti-slip texture 102, connecting lug 103, mating recess 104, positioning post 105, arc-shaped protrusion 106, mating arc groove 107, connecting rod 2, connecting seat 201, rotating bar 202, vertical pipe 3, railing pipe 301, and connecting hoop 302, are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0027] Example 1
[0028] Please see Figures 1-4 As shown, this utility model provides a technical solution: a combined pile foundation working platform, comprising:
[0029] Float 1, connecting rod 2, and vertical pipe 3;
[0030] Among them, the outer surface of the float 1 is provided with arc-shaped protrusions 106 and matching arc grooves 107. The four corners of the outer surface of the float 1 are provided with connecting ears 103, and the inner surface of one end of the connecting ear 103 is provided with an insertion through hole. The four corners of the top of the float 1 are provided with mating recesses 104.
[0031] The connecting rod 2 is inserted into the through hole of the connecting ear 103, the upper end of the connecting rod 2 is threaded with the connecting seat 201, and the groove at the bottom of the connecting rod 2 is provided with a rotating bar 202.
[0032] The vertical tube 3 is inserted into the inner side of the docking recess 104, and a connecting sleeve 302 is installed on the outer surface of the vertical tube 3. The guard tube 301 is installed on the vertical tube 3 through the connecting sleeve 302.
[0033] The float 1 has a hollow structure and is made of strong and tough high molecular weight polyethylene. The positions of the arc-shaped protrusion 106 and the matching arc groove 107 are corresponding, and the arc-shaped protrusion 106 and the matching arc groove 107 are adapted to each other. The heights of the four connecting ears 103 on the outer surface of the float 1 are different, and the height difference between two adjacent connecting ears 103 is equal to the thickness of the connecting ear 103 itself in the counterclockwise direction.
[0034] This technical solution: First, the main body of the platform is assembled. The first float 1 is placed on the water surface, and then the second float 1 is brought closer to it. During the process of bringing them closer, the arc-shaped protrusion 106 on one float and the matching arc groove 107 on the other float are used for initial alignment and fitting. When the four floats 1 are gathered at the center, since the four connecting ears 103 on the outer surface of each float 1 have a preset height difference equal to their own thickness in the counterclockwise direction, these connecting ears 103 will naturally be stacked in layers, so that the through holes on all connecting ears 103 are completely connected in the vertical direction.
[0035] Next, take a connecting rod 2 and insert it vertically from below into the through hole of the stacked connecting lugs 103 (diver assistance is required because vertical insertion of the connecting rod 2 from below avoids the drive from loosening when personnel move around; similarly, it can also be inserted vertically from above as needed). The rotating bar 202 at the bottom of the connecting rod 2 makes it easy to apply force by hand. After the connecting rod 2 passes through all the connecting lugs, screw the connecting seat 201 into the upper end of the connecting rod 2 and tighten it. At this time, the bottom of the connecting seat 201 and the bottom of the connecting rod 2 are respectively embedded in the corresponding arc-shaped positioning notch 101, forming a flat joint. Then, the four floats 1 can be firmly locked together by the thread preload. By repeating this process, more floats 1 can be connected in the same way to quickly expand into a working platform of the required size (in addition, this platform can also be pre-assembled on the construction vessel and placed on the water surface).
[0036] After the main platform is built, the safety railing is installed. The lower end of the vertical pipe 3 is inserted into the docking recess 104 at the top corner of the pontoon. Then, the railing pipe 301 is horizontally fixed between the adjacent vertical pipes 3 using the connecting clamp 302, thus quickly forming a complete safety railing system.
[0037] In summary, the entire platform construction process requires no complex tools or heavy water equipment, is easy to operate, and has reliable connections, greatly improving construction efficiency and safety.
[0038] Example 2
[0039] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a positioning post 105 is provided on the inner side of the docking recess 104, and the positioning post 105 is adapted to the inner wall of the vertical tube 3.
[0040] This technical solution: By setting the positioning post 105, when the positioning post 105 in the receiving hole 104 is further inserted into the vertical tube 3, it can provide additional positioning and anti-tilting ability, thus ensuring the upright stability of the vertical tube 3.
[0041] Example 3
[0042] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the float 1 has arc-shaped positioning notches 101 at both the upper and lower corners, and the arc-shaped positioning notches 101 are adapted to the outer surfaces of the connecting seat 201 and the lower end of the connecting rod 2, and the top of the connecting seat 201 is provided with an anti-slip groove.
[0043] This technical solution: By setting the arc-shaped positioning notch 101, the bottom of the connecting seat 201 and the bottom of the connecting rod 2 can be embedded into the corresponding arc-shaped positioning notch 101 respectively, forming a flat joint, which not only ensures the flatness of the platform surface, but also avoids the safety hazards caused by protrusions.
[0044] Example 4
[0045] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the top of the pontoon 1 is provided with anti-slip texture 102.
[0046] This technical solution: By setting the anti-slip texture 102, the top of the float 1 can effectively increase the friction of the working surface and prevent personnel from slipping.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
