Description

A floating seal plug for offshore steel pipe piles

technical field

The utility model relates to the offshore floating transportation of steel pipe piles in large-scale projects at sea, in particular to a floating transportation sealing plug for offshore steel pipe piles, which is used for the head and tail sealing of steel pipe piles.

Background technique

With the continuous development and utilization of marine resources by humans, more and more projects need to be implemented at sea, and most of the large-scale offshore projects rely on large-scale steel structures. Steel pipe piles are a very important part of large-scale offshore steel structures. At present Steel pipe piles usually have a diameter of 4-10m and a length of 30-80m. Its huge volume and mass make the transportation process difficult. The use of special transportation ships is inefficient and expensive. posed great challenges. Therefore, a method of floating transportation of steel pipe piles has emerged, which seals both ends of the steel pipe piles, floats on the sea surface by using its own buoyancy, and then hauls them to the construction site by a tugboat, which can increase transportation efficiency and save transportation costs. However, this This method has high requirements on the watertightness of the steel pipe pile floating device.

Contents of the invention

In order to overcome the shortcomings in the above-mentioned background technology, the utility model provides a sealing plug for offshore steel pipe pile floating transportation, which has a simple structure, is convenient for loading and unloading, and has strong sealing performance.

In order to achieve the above technical purpose, the utility model provides a solution: a floating sealing plug for offshore steel pipe piles, including a rubber ring, a steel dome, and a steel groove for fixing the rubber ring. The steel dome and the The steel channel is fixedly connected, and the steel channel is provided with an inflation port for inflating the rubber ring, and the limit barbs are evenly distributed on the circumference of the steel channel.

In the above technical solution, a tire pressure gauge is provided on the inflation port.

In the above technical solution, the steel channel is fixedly connected to the central reinforcement cylinder located at the center of the steel channel through the outer ring support arm, and the central reinforcement cylinder is provided with a central reinforcement bracket connected to the steel dome.

In the above technical solution, the central reinforcement cylinder is provided with a central lifting lug, and the steel channel and the outer ring support arm are provided with auxiliary lifting lugs.

The sealing plug of the utility model adopts an inflatable seal, which changes the traditional way of hydraulic cylinder extruding hard rubber to realize sealing, avoids the problem of using the hydraulic cylinder itself to install oil tight reliability, and at the same time, the new sealing plug has better durability It is more reliable and safe, and it is more convenient to disassemble. When in use, inflate the sealing plug. When it reaches a certain air pressure, it will stop inflating when it reaches the sealing level, and use the air pressure detection device to maintain the air pressure of the steel pipe under different sea conditions. The tightness of the pile, and it has a buffering effect when subjected to wave loads. It is more resistant to impact than hard rubber, and has a protective effect on steel pipe piles, with better safety. When the steel pipe pile is transported to the construction site, the sealing plug can be released only by exhausting the sealing plug, so the disassembly process of the sealing plug is relatively simple and the construction efficiency is improved. In addition, the cushioning performance of the inflatable device is excellent, and the cycle service life of the sealing plug will also be greatly improved.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figures 2, 3, and 4, this embodiment provides a floating sealing plug for offshore steel pipe piles, including a rubber ring 10, a steel dome 11, and a steel groove 12 for fixing the rubber ring. The quality dome 11 is fixedly connected with the steel channel 12, and the steel channel 12 is provided with an inflation port for inflating the rubber ring 10. The inflation port is provided with a tire pressure gauge, and the limit barb 9 is evenly distributed on the circumference of the steel channel 12. . The steel channel 12 is fixedly connected with the central reinforcing cylinder 3 located at the center of the steel channel 12 through the outer ring support arm 6 , and the central reinforcing column 3 is provided with a central reinforcing bracket 4 connected with the steel dome 11 .

The central reinforcement cylinder 3 is provided with a central lug 5 , and the steel channel 12 and the outer ring support arm 6 are provided with auxiliary lugs 7 .

Among them, the central reinforced cylinder 3, the central reinforced bracket 4, and the outer ring support arm 6 are all reinforced structures of the sealing plug 2, the auxiliary lifting lug 7 can be used for binding other auxiliary devices, and the steel dome 11 is a watertight area without openings .

As shown in Figures 1 and 5, when installing on shore, the central lug 5 and auxiliary lug 7 are connected to other hoisting machinery, and the sealing plug 2 is hoisted to the head or tail end of the steel pipe pile 1 to limit the barb. 9 is the benchmark to straighten the sealing plug 2, then inflate the rubber ring 10 from the inflation port, the inflated rubber ring generates pressure on the steel pipe pile wall, and the pressure can be monitored by the tire pressure gauge.
