Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile fender installation, specifically to a clamp-type fender for steel pipe piles. Background Technology

[0002] Steel pipe piles are widely used in harbor structures, serving as the foundation for sea-crossing bridges, high-pile wharves, and offshore platforms. Some non-load-bearing steel pipe piles primarily function to provide lateral collision buffers for offshore wharf ancillary structures (such as lifting piers). Therefore, to improve the stability and safety of these ancillary structures, it is usually necessary to design and install an impact-damping fender structure on the sides of the steel pipe piles to ensure that these ancillary structures do not experience severe lateral swaying or instability during use.

[0003] Traditionally, the installation of steel pipe pile fenders involves welding vertical steel plates to the sides of the steel pipe piles after pile driving to serve as fixing points for the rubber fenders. However, this method has several drawbacks: 1) Offshore welding is a complex process that requires the construction of specialized work platforms, which poses high safety risks and is inefficient. 2) The anti-corrosion layer of steel pipe piles may be damaged during welding, making repairs at sea difficult and significantly increasing the risk of pile corrosion. 3) Damaged fenders are difficult to maintain, lack modular design, have high replacement costs, and affect terminal operations; 4) The fenders cannot be disassembled or moved, and cannot adapt well to possible changes in water level. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp-type fender for steel pipe piles, which solves the problems of inconvenience in disassembling and moving the fender after installation and inability to adapt to changes in water level.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a clamp-type fender for steel pipe piles, including a fender and multiple clamp structures; The fender is set vertically, and the side wall of the fender has multiple first mounting holes along the vertical direction; The clamp structure includes a first semicircular clamp, a second semicircular clamp, and a mounting plate. The first semicircular clamp has mating plates on both sides with mating holes. The second semicircular clamp has the same structure as the first semicircular clamp. Bolts pass through the mating holes of the first and second semicircular clamps for fixing and for clamping the steel pipe pile. The mounting plate is set on the first semicircular clamp and has a second mounting hole that matches the first mounting hole. Bolts pass through the first and second mounting holes for fixing and for connecting the fender.

[0006] As a further technical solution to the above scheme, rubber pads are provided on the inner sides of the first semicircular clamp and the second semicircular clamp.

[0007] As a further technical solution to the above scheme, a stiffening rib is provided between the first semicircular clamp, the second semicircular clamp and the connecting plate.

[0008] As a further technical solution of the above solution, the two side walls of the fender are provided with a plurality of first mounting holes in the vertical direction; two mounting plates are provided, which are respectively connected to the two sides of the fender through the second mounting holes. Compared with the prior art, this utility model has the following advantages and beneficial effects: This device connects the clamp structure and the fender into a whole by setting an installation plate. The first semicircular clamp and the second semicircular clamp are tightly clamped on the steel pipe pile. The fender is in contact with the auxiliary structure of the marine wharf, providing lateral anti-collision buffer. When the water level changes, the first semicircular clamp and the second semicircular clamp can be disassembled and moved, driving the fender to move to different positions to adapt to the change of water level.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0015] like Figures 1-4 As shown, a clamp-type fender for steel pipe piles includes a fender 1 and multiple clamp structures 2; The fender 1 is vertically installed, and the side wall of the fender 1 is provided with multiple first mounting holes along the vertical direction; The clamp structure 2 includes a first semicircular clamp 21, a second semicircular clamp 22, and a mounting plate 23. The first semicircular clamp 21 has mating plates 24 on both sides, and mating holes 25 on the mating plates 24. The second semicircular clamp 22 has the same structure as the first semicircular clamp 21. Bolts are fixed by passing through the mating holes 25 of the first semicircular clamp 21 and the second semicircular clamp 22, which are used to clamp the steel pipe pile 3. The mounting plate 23 is set on the first semicircular clamp 21 and has a second mounting hole that matches the first mounting hole. Bolts are fixed by passing through the first mounting hole and the second mounting hole, which are used to connect the fender 1.

[0016] When using this device, the clamp structure 2 is used to clamp the steel pipe pile 3. First, the mounting plate 23 is aligned with the fender 1. Multiple clamp structures 2 are set along the vertical direction of the fender 1. The clamp structures 2 are preferably set at equal intervals. After the position is determined, bolts are used to pass through the first mounting hole and the second mounting hole to fix them together, connecting the clamp structure 2 and the fender 1. After the whole device is connected, it is inserted into the steel pipe pile 3. The first semi-circular clamp 21 and the second semi-circular clamp 22 clamp the steel pipe pile 3. Bolts are used to pass through the docking hole 25 on the docking plate 24 to fix them, so that the first semi-circular clamp 21 and the second semi-circular clamp 22 close together to form a circular clamp structure and clamp the steel pipe pile 3. The fender 1 is installed on the side wall of the steel pipe pile 3 through the clamp structure 2 to play a buffer role. When the water level drops or rises, the contact position between the marine dock auxiliary structure and the steel pipe pile 3 will also change accordingly. At this time, the bolts on the docking plate 24 are loosened, and the upper and lower positions of the fender 1 on the steel pipe pile 3 are adjusted to adapt to the water level change. Fender 1 is made of elastomeric polymer material and can be modularly combined through multiple rubber units, facilitating subsequent replacement and maintenance. The modular rubber fender 1 has good elasticity, flexibility, and energy absorption characteristics. Construction using the clamp structure 2 avoids offshore welding operations, effectively improving construction efficiency, reducing offshore construction time, and effectively mitigating construction risks.

[0017] like Figure 3 and Figure 4 As shown, in a preferred embodiment, rubber pads 5 are provided on the inner sides of the first semicircular clamp 21 and the second semicircular clamp 22. In this embodiment, the rubber pads 5 provided on the inner sides of the first semicircular clamp 21 and the second semicircular clamp 22 serve to prevent slippage and secure the connection with the steel pipe pile 3.

[0018] like Figure 3 and Figure 4 As shown, in a preferred embodiment, a stiffening rib 4 is provided between the first semicircular clamp 21, the second semicircular clamp 22, and the mating plate 24. In this embodiment, the stiffening rib 4 improves the connection stability between the first semicircular clamp 21, the second semicircular clamp 22, and the mating plate 24.

[0019] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the two side walls of the fender 1 are provided with multiple first mounting holes along the vertical direction; two mounting plates 23 are provided, which are respectively connected to the two sides of the fender 1 through second mounting holes. In this embodiment, first mounting holes are provided on both sides of the fender 1, and the two mounting plates 23 are respectively connected to the two sides of the fender 1, which improves the stability of the device.
