[0025] Reference Figure 1 and Figure 2 Describe a deep - water steel pipe pile intelligent ultra - high - pressure water jet cutting machine according to an embodiment of the present utility model.

[0026] As Figure 1 and Figure 2 shown, the deep - water steel pipe pile intelligent ultra - high - pressure water jet cutting machine according to the embodiment of the present utility model includes: a steel pipe track disc 100, the diameter of the steel pipe track disc 100 is smaller than the diameter of the steel pipe pile 10, and the steel pipe track disc 100 is suspended inside the steel pipe pile 10 by a steel wire rope 110; a cutting track 200, the cutting track 200 is circular - ring - shaped, and the cutting track 200 is arranged on the inner wall of the steel pipe track disc 100; a cutting mechanism 300, the cutting mechanism 300 is arranged on the cutting track 200, and the cutting mechanism 300 moves along the cutting track 200 to cut the steel pipe pile 10.

[0027] Since the steel pipe pile 10 needs to be cut 1 m below the mud surface, for conventional underwater cutting by divers, it is necessary to clean the silt layer around the steel pipe pile 10 in advance using a grab dredger. The amount of silt cleaning work is large and the safety risk is high. When using the intelligent ultra-high pressure water jet cutting machine for deep water steel pipe piles in this construction, there is no need for divers to enter the water. Before cutting, a mud pump is used to suck mud inside the steel pipe pile 10. The mud suction range is small and the efficiency is high. Then, the water knife is lowered for intelligent cutting, which greatly reduces the safety risk and saves costs at the same time.

[0028] As Figure 1 and Figure 2 shown, the intelligent ultra-high pressure water jet cutting machine for deep water steel pipe piles further includes a limiting plate 120. The limiting plate 120 is arranged outside the steel pipe track disc 100 and abuts against the inner wall of the steel pipe pile 10. The limiting plate 120 is used to stabilize the steel pipe track disc 100. As Figure 2 shown, there are four limiting plates 120, and the four limiting plates 120 are evenly distributed along the circumferential direction of the steel pipe track disc 100.

[0029] As Figure 1 and Figure 2 shown, the cutting mechanism 300 includes a driving motor 310 and a rotary cutting head 320. The driving motor 310 is arranged on the cutting track 200, and the rotary cutting head 320 is arranged at the lower end of the driving motor 310. The rotary cutting head is arranged along the radial direction of the steel pipe track disc 100, and the rotary cutting head 320 extends towards the inner wall of the steel pipe pile 10. The driving motor 310 is used to drive the rotary cutting head 320 to move along the cutting track 200. The rotary cutting head 320 is connected with a pipeline 330, and the rotary cutting head 320 is communicated with a high-pressure water source through the pipeline 330. The cutting track 200 includes a water knife track chain, and the water knife track chain is in a ring shape.

[0030] In some specific embodiments of the present utility model, a camera is installed on the rotary cutting head 320. The camera is used to observe the underwater cutting condition, which is convenient for the operator to observe the underwater cutting condition in real time.

[0031] When using this intelligent ultra-high pressure water jet cutting machine for deep-water steel pipe piles to cut the steel pipe pile 10, first use a mud pump to suck mud inside the steel pipe pile 10. The steel wire rope 110 hoists the steel pipe track disc 100 into the steel pipe pile 10. The limiting plate 120 on the circumferential side of the steel pipe track disc 100 abuts against the inner wall of the steel pipe pile 10 to ensure that the steel pipe track disc 100 does not deviate or shake. When the steel pipe track disc 100 is lowered until the rotary cutting head 320 is aligned with the cutting line of the steel pipe pile 10, the drive motor 310 starts to drive the rotary cutting head 320 to move along the annular water jet track chain. The rotary cutting head 320 is connected to the high-pressure water source through the pipeline 330. The high-pressure water source provides sufficient energy for cutting, and the pressurized water flow is ejected through the rotary cutting head 320. The fine water flow impacts the material to be cut at an extremely high speed under the action of the rotary cutting head 320 to achieve the cutting effect. During the cutting process, the water flow not only cuts the material but also plays a cooling role to prevent the cutting area from overheating.

[0032] Therefore, this intelligent ultra-high pressure water jet cutting machine for deep-water steel pipe piles adopts the intelligent ultra-high pressure water jet cutting technology for deep-water steel pipe piles without divers. It does not require divers to work underwater, ensuring the construction quality while greatly reducing safety risks. At the same time, it dredges the silt inside the steel pipe pile 10, significantly reducing the workload and saving costs. Compared with conventional thermal cutting, the ultra-high pressure water jet cutting machine uses water flow as the cutting medium, which is a cold cutting process. It is controlled by a numerical control system, with high cutting precision, and no waste that pollutes the environment is generated during the cutting process.

[0033] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
