Description

Technical Field

[0001] The utility model relates to the technical field of oil pipelines, in particular to an oil pipe heat treatment device. Background Art

[0002] Oil pipelines are mainly used for long-distance, large-scale transportation of liquid energy such as crude oil, refined oil and natural gas condensate. These pipelines are important infrastructure for global energy transportation and undertake the key task of transporting oil and natural gas from production areas to refineries, storage facilities and end users.

[0003] Oil pipelines need to have high pressure resistance, compressive strength, yield strength and toughness, especially in deep sea or high-cold environments. Oil pipelines need to be treated accordingly. In deep sea environments, pipelines not only have to withstand huge water pressure, but also face complex seabed terrain and water flow impact. Therefore, special anti-corrosion treatment and structural design are required to ensure their stability and safety. In high-cold areas, pipeline materials need to maintain good toughness at low temperatures to prevent brittleness and rupture due to low temperatures. At the same time, insulation measures need to be taken to prevent oil from solidifying due to low temperatures and affecting transportation efficiency.

[0004] Pipeline heat treatment plays a vital role in the construction and operation of oil pipelines. Through heat treatment, the internal structure of the pipeline material can be changed, thereby improving its mechanical properties. For example, the prior application with publication number CN207555059U discloses a mobile pipeline heat treatment device, which clamps the pipeline by a rotating rod and a spring and moves it to the heat treatment process for treatment. However, since the diameter of an oil pipeline is generally more than one meter, it is difficult to clamp and quickly move the oil pipeline using a rotating rod and a spring, resulting in low oil pipeline production efficiency.

[0005] Therefore, those skilled in the art are committed to developing an oil pipe heat treatment device, which is conducive to quickly heat treating large-diameter oil pipelines and improving pipeline production efficiency. Utility Model Content

[0054] The lifting assembly 8 is located between the heat treatment assembly 6 and the cooling assembly 7 .

[0055] In the utility model, the rail flatbed vehicle 1 moves on the moving rail 2, and the oil pipeline can be quickly passed through the preheating component 5, the heat treatment component 6 and the cooling component 7 in sequence, so that the oil pipeline can be heat treated in a reasonable order, thereby ensuring the uniformity and stability of the heat treatment effect and improving the quality of the oil pipeline.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the rail flatbed vehicle 1 includes a base plate 9, a hoisting plate 10 and a track wheel. The base plate 9 is made of high-strength steel, and the surface is finely rust-proofed to ensure that it can maintain good performance even in harsh working environments. The track wheel is installed at the bottom of the base plate 9 and is compatible with the moving track 2. The track wheel can be made of alloy steel with excellent wear resistance. After precision machining, its fit with the track and running accuracy are guaranteed. The hoisting plate 10 is located on the base plate 9, and a limiting column for limiting the hoisting plate 10 is installed on the base plate 9. The area of ​​the base plate 9 is larger than the area of ​​the hoisting plate 10. After the hoisting plate 10 is placed on the base plate 9, multiple limits on the base plate 9 limit and fix the hoisting plate 10 to prevent the hoisting plate 10 from excessive displacement or shaking during movement. A hoisting ear 11 is also installed on the hoisting plate 10. The pipe clamping assembly 3 and the pipe fixing assembly 4 are both installed on the hoisting plate 10. The hoisting ear 11 is made of high-temperature resistant metal material and can withstand large tensile forces at high temperatures.

[0057] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a plurality of spaced-apart pipe clamping assemblies 3 are installed on the lifting plate 10 for clamping the oil pipe 14. The pipe clamping assembly 3 includes a first clamping roller 12 and a second clamping roller 13. The first clamping roller 12 and the second clamping roller 13 are both made of high-temperature resistant metal. The first clamping roller 12 and the second clamping roller 13 are respectively located on both sides of the oil pipe 14. The first clamping roller 12 is installed on the rail flatbed trolley 1 through a roller support frame 15, and the second clamping roller 13 is installed on the rail flatbed trolley 1 through an adjustment assembly 16.

[0058] Specifically, the adjustment component 16 includes a sliding block 17, a guide rail 18 and a support plate 19. The second clamping roller 13 is installed on the sliding block 17 through a support frame. The guide rail 18 is installed on a mounting plate 39. A sliding block matching the guide rail 18 is installed at the bottom of the sliding block 17. The mounting plate 39 is installed on the rail flatbed car 1 and a support plate 19 is also fixedly installed on the mounting plate 39. The support plate 19 is vertically arranged. A rotating screw 20 is installed on the support plate 19 through a screw support seat. One end of the rotating screw 20 is rotatably connected to the sliding block 17 through a screw connecting seat. A rotating handle 21 is installed on the other end of the rotating screw 20. The rotating handle 21 rotates to drive the rotating screw 20 to rotate, so that the sliding block 17 slides along the guide rail 18 to adjust the distance between the first clamping roller 12 and the second clamping roller 13, thereby clamping oil pipes 14 of different diameters.

[0059] like Figure 2 , Figure 3As shown, in one embodiment, the pipe fixing assembly 4 is used to fix the end of the oil pipe 14 to prevent the oil pipe 14 from loosening at the end during the heat treatment process and affecting the overall stability. The pipe fixing assembly 4 includes an articulated seat 22 hingedly mounted on the rail flatbed vehicle 1, the articulated seat 22 is hingedly connected with an adjusting screw 23, and a clamping block 24 cooperating with the adjusting screw 23 is arranged outside the adjusting screw 23. Specifically, the clamping block 24 has a threaded hole cooperating with the adjusting screw 23, and a clamping groove for clamping the end of the oil pipe 14 is provided on the side wall of the clamping block 24. The clamping block 24 is moved along the axial direction of the adjusting screw 23 by rotating the clamping block 24 to adjust the height of the clamping block 24. When the clamping block 24 is adjusted to a suitable height, the clamping groove clamps the wall of the oil pipe 14. The pipe fixing assembly 4 and the pipe clamping assembly 3 cooperate to clamp the oil pipe 14 firmly to prevent displacement or shaking during heat treatment.

[0060] like Figure 1 , Figure 5 and Figure 6 As shown, in the embodiment, the main function of the preheating assembly 5 is to preliminarily heat the oil pipe 14. Specifically, the preheating assembly 5 includes a preheating chamber 25, and the preheating chamber 25 has a preheating chamber for accommodating the rail flatbed vehicle 1. The first hoisting door assembly is installed on both sides of the preheating chamber 25. The first hoisting door assembly can be conveniently opened and closed when the rail flatbed vehicle 1 needs to enter and exit the preheating chamber 25, and at the same time, the sealing of the preheating chamber 25 is ensured during the preheating process to prevent heat loss.

[0061] A plurality of first high-frequency heating components 26 and first temperature sensors 27 are installed in the preheating chamber 25, and the first high-frequency heating components 26 and the first temperature sensors 27 are electrically connected to a control device (not shown in the figure). The first high-frequency heating components 26 can generate a high-frequency electromagnetic field, so that the free electrons inside the oil pipe 14 move at high speed under the action of the high-frequency alternating electromagnetic field, collide and rub with metal atoms, thereby generating heat, and achieving rapid and uniform heating of the oil pipe 14. The first temperature sensor 27 monitors the temperature in the preheating chamber in real time, and feeds back the temperature signal to the control device, which regulates the first high-frequency heating components 26 according to the preset temperature parameters to ensure the stability and accuracy of the preheating process.

[0062] like Figure 1 , Figure 7As shown, in some embodiments, the heat treatment component 6 and the preheating component 5 are similar in structure, and the only difference is that the temperature in the heat treatment component 6 is higher and needs to be kept warm for a period of time. Specifically, the heat treatment component 6 includes a heat treatment chamber 28, the heat treatment chamber 28 has a heat treatment chamber for accommodating the rail flatbed car 1, and the heat treatment chamber 28 is equipped with a second hoisting door assembly on both sides. A plurality of second high-frequency heating components 29 and a second temperature sensor 30 are installed in the heat treatment chamber 28, and the second high-frequency heating component 29 and the second temperature sensor 30 are electrically connected to a control device. The second high-frequency heating component 29 is mainly used for heating during the heat treatment process, and its working principle is the same as that of the first high-frequency heating component 26, but according to the requirements of the heat treatment process, the second high-frequency heating component 29 has a larger power and a higher frequency to meet the temperature requirements of the oil pipe 14 at different heat treatment stages. The second temperature sensor 30 monitors the temperature changes in the heat treatment chamber in real time, and transmits the data to the control device. The control device accurately controls the second high-frequency heating component 29 according to the preset heat treatment curve and temperature parameters to ensure that the heat treatment process of the oil pipe 14 is strictly carried out in accordance with the process requirements, thereby obtaining ideal metallographic structure and mechanical properties.

[0063] like Figure 5 As shown, in the embodiment, the first hoisting door assembly and the second hoisting door assembly both include a sealing door 31, which is made of heat-insulating and high-temperature resistant materials, can effectively block heat loss, and maintain good sealing performance in a high-temperature environment. The upper end of the sealing door 31 is connected to the lifting assembly 8 through a lifting assembly 40. In this embodiment, the lifting assembly 40 includes a threaded rod, which is connected to the sealing door 31. The outer sleeve of the threaded tube is provided with a screw bearing that matches the threaded tube. The outer ring of the screw bearing is connected to a worm gear. A motor is installed on the lifting assembly 8, and a worm that matches the worm gear is installed at the output end of the motor. The rotation of the motor drives the worm, the worm gear and the screw bearing to rotate in turn, thereby driving the threaded rod and the sealing door 31 to move up and down.

[0064] In other embodiments, the lifting assembly 40 may be an electric hoist, a hydraulic lifter or other equipment, which has stable lifting performance and sufficient carrying capacity, and can smoothly lift or lower the sealed door 31 to realize the opening and closing operation of the hoisting door. When the rail flatbed vehicle 1 enters and exits the preheating chamber 25 or the heat treatment chamber 28, the lifting assembly 40 drives the sealed door 31 to rise, making way for the rail flatbed vehicle 1 to enter and exit. During the preheating or heat treatment process, the sealed door 31 is tightly attached to the door of the preheating chamber 25 or the heat treatment chamber 28 under the action of the lifting assembly 40, ensuring that the heat in the chamber will not be lost in large quantities, and maintaining a stable temperature environment.

[0065] like Figure 1As shown, the cooling assembly 7 includes a cooling box 32, and the cooling box 32 has a cooling cavity 33, and the cooling cavity 33 is filled with a coolant, and the coolant can be water, salt water or oil. During the cooling process, the oil pipe 14 enters the cooling cavity 33 of the cooling box 32 under the action of the lifting assembly 8, and the coolant quickly takes away the heat of the oil pipe 14, thereby realizing rapid cooling of the oil pipe 14. The cooling box 32 has sufficient strength and stability to withstand the weight of the coolant and the impact force of the oil pipe 14 during the cooling process. At the same time, the cooling box 32 is also equipped with a liquid level monitoring device and a coolant circulation system to ensure that the liquid level of the coolant is always within an appropriate range and to maintain the cooling performance of the coolant stable.

[0066] like Figure 1 , Figure 8 As shown, in this embodiment, the lifting assembly 8 includes a lifting rail 34 and a lifting mechanism 35, and the lifting assembly 8 can also be directly hoisted. The lifting mechanism 35 is arranged on the lifting rail 34, and the lifting mechanism 35 has a lifting plate 36, and a lifter 37 is installed on the lifting plate 36. The lifter 37 can be an electric hoist, and the output end of the lifter 37 is connected to a hook 38 that cooperates with the lifting ear 11. During the lifting operation, the hook 38 is connected to the lifting ear 11 on the rail flatbed car 1, and the lifting mechanism 35 moves between the heat treatment bin 28 and the cooling box 32 through the lifting rail 34, and the heat-treated oil pipe 14 is transferred from the heat treatment bin 28 to the cooling box 32 for cooling, and finally lifted to the placement position to complete the entire heat treatment process. The entire lifting process has a high degree of automation, is easy to operate, and has stable and reliable operation, providing an efficient and convenient material transfer solution for the heat treatment of the oil pipe 14.
