Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically to a large-diameter pipe cooling device. Background Technology

[0002] Large-diameter pipes refer to pipe fittings with a diameter of DN250 or larger. The main materials include carbon steel, stainless steel, and alloy steel. In modern industry, large-diameter pipes are widely used in many key sectors such as oil and natural gas transportation, urban water supply and drainage projects, and large building structural support. With the continuous advancement of infrastructure construction and the sustained expansion of industrial production scale, the demand for large-diameter pipes is not only increasing in quantity but also placing higher demands on their quality and performance.

[0003] Traditional cooling technologies for large-diameter pipes have many drawbacks. Some simple cooling methods, such as natural cooling, are extremely inefficient, leading to significantly longer production cycles and making it difficult to meet the needs of large-scale industrial production. While some spray cooling equipment suffers from improperly distributed cooling nozzles, failing to achieve uniform cooling of the pipe from all directions, resulting in inconsistent cooling rates across different parts of the pipe and causing quality problems such as deformation and cracking. Furthermore, most cooling devices struggle to stabilize the pipe during the cooling process, leading to poor equipment stability. Utility Model Content

[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. 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.

[0015] Example: Figure 1-3As shown, this utility model provides a large-diameter pipe cooling device, including a support platform 11. Support legs 14 are symmetrically fixedly fitted onto both sides of the support platform 11 and adjustable pins 15 are inserted therein. Multiple corresponding adjustable grooves are formed on the outer surfaces of both the support legs 14 and the support platform 11. The adjustable pins 15 cooperate with the adjustable grooves to adjust the relative position of the support platform 11 and the support legs 14, thereby flexibly adjusting the height of the device to adapt to different working environments and pipe placement requirements, enhancing the adaptability and practicality of the device. A cooling shell 12 is fixedly connected to the upper surface and a pressure pump 16 is fixedly installed thereon. Supports 17 are symmetrically fixedly connected to both ends of the cooling shell 12. A cylinder 18 is fixedly installed on one side of the support 17. An arc-shaped clamp 19 is fixedly connected to the output end of the cylinder 18. The outer surface of the arc-shaped clamp 19 is treated with anti-slip treatment. When the cylinder 18 pushes the arc-shaped clamp 19 to fix the pipe, the anti-slip treatment can increase the friction between the clamp and the pipe, prevent the pipe from displacing or rolling abnormally during the cooling process, and ensure the stability of the pipe during the cooling process.

[0016] The lower inner walls of the cooling housing 12 are symmetrically and elastically connected with lower arc-shaped support plates 21, and the upper inner walls of the cooling housing 12 are fixedly connected with upper arc-shaped support plates 22. The diameter of the lower arc-shaped support plates 21 is the same as that of the upper arc-shaped support plates 22. Multiple springs 20 arranged in a rectangular array are fixedly installed on the lower inner wall of the cooling housing 12, and the top of the springs 20 is fixedly connected to the lower arc-shaped support plates 21. The lower arc-shaped support plates 21 can better cooperate in clamping the pipe. The elastic support provided by the springs 20 can not only adapt to pipes of different weights, but also play a buffering role during the placement and cooling of the pipe, ensuring the stable support of the pipe and avoiding damage to the surface of the pipe due to rigid contact.

[0017] The upper surface of the cooling housing 12 is symmetrically threaded with threaded rods 23. The bottom end of the threaded rod 23 passes through the cooling housing 12 and is fixedly connected to the upper arc-shaped support plate 22. The top end of each threaded rod 23 is fixedly fitted with a handwheel 24. By rotating the handwheel 24, the threaded rod 23 can be easily rotated, thereby precisely adjusting the position of the upper arc-shaped support plate 22. The operator can adjust the distance between the upper and lower arc-shaped support plates 21 by rotating the handwheel 24 at the top end of the threaded rod 23 to accommodate large-diameter pipes of different diameters. The bracket 17 is connected to both ends of the cooling housing 12, and the cylinder 18 installed on it can push the arc-shaped clamp 19 to fix the pipe and prevent the pipe from moving during the cooling process.

[0018] Multiple supports 25 are fixedly installed inside the cooling housing 12. The upper surface of each support 25 is arc-shaped and smooth. The arc design matches the circular cross-section of the pipe, providing better support and making it more stable. The smooth surface reduces friction between the pipe and the support 25, facilitating pipe movement. A cooling pipe 26 is fixedly inserted into the outer surface of each support 25. The output end of the pressure pump 16 is fixedly connected to the cooling pipe 26. Multiple nozzles 27 are fixedly connected to the outer surface of the cooling pipe 26. The nozzles 27 are arranged in a ring, which allows the cooling medium to cover the pipe surface in all directions, achieving uniform spray cooling of the pipe and greatly improving the cooling efficiency and uniformity of the cooling effect. Multiple cooling fans 28 are symmetrically fixed on the inner surface of the cooling shell 12. When the pressurizing pump 16 is working, it delivers the cooling medium to the cooling pipe 26, and then sprays the pipe in all directions through the nozzles 27. The multiple nozzles 27 fixed on the outer surface of the cooling pipe 26 are arranged in a ring to ensure that the pipe surface is heated evenly and improve the cooling efficiency.

[0019] Working Principle: First, by adjusting the pin 15 in conjunction with the adjusting grooves on the outer surfaces of the support leg 14 and the support platform 11, the relative position of the support leg 14 and the support platform 11 is adjusted to ensure the entire device is at a suitable height and in a stable state. Then, the operator rotates the handwheel 24, driving the threaded rod 23 to rotate, causing the upper arc-shaped support plate 22 to move up and down within the cooling housing 12, cooperating with the lower arc-shaped support plate 21 to adjust the clamping space suitable for the pipe diameter. Large-diameter pipes are placed on the support 25 within the cooling housing 12. Because the upper surface of the support 25 is arc-shaped and smooth, the pipe can be easily positioned and can roll smoothly in subsequent processes. After the pipe is placed, the cylinder 18 is activated, extending to push the arc-shaped clamping plate 19 towards the pipe. The outer surface of the arc-shaped clamping plate 19 is treated with an anti-slip coating, allowing it to tightly adhere to the pipe surface, effectively fixing and assisting in positioning the pipe, preventing displacement or abnormal rolling during cooling, and ensuring the stability of the cooling operation.

[0020] When cooling is required, the pressurization pump 16 is activated, delivering the cooling medium (such as water or coolant) to the cooling pipe 26 through its output end. Multiple nozzles 27 are fixed to the outer surface of the cooling pipe 26 in a circular pattern. Under pressure, the cooling medium is ejected from the nozzles 27, forming a fine cooling spray that comprehensively covers the pipe surface. Simultaneously, multiple cooling fans 28 symmetrically mounted on the inner surface of the cooling housing 12 start. On one hand, the airflow generated by the cooling fans 28 accelerates airflow within the cooling housing 12, promoting the evaporation of the cooling medium and heat dissipation, further enhancing the cooling effect. On the other hand, the airflow also helps to promptly remove the heat generated during the cooling process from the cooling housing 12, maintaining the stability of the cooling environment.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
