Description

Technical Field

[0001] This utility model belongs to the technical field of oil lifting ring production equipment, specifically relating to a device for induction heating of the rod section of an oil lifting ring. Background Technology

[0002] In the oil drilling industry, the lifting ring is a critical drilling rig component, primarily used to connect the drill pipe and drill collar, playing a vital role in suspending the drill string and transmitting drilling pressure. The quality of the lifting ring directly affects the safety and efficiency of drilling operations. In the production process of oil lifting rings, the bending and forming of the rod section is a crucial step, determining the strength and reliability of the lifting ring. Improper bending and forming of the rod section can not only affect the performance of the lifting ring but also lead to drilling accidents, causing economic losses and safety incidents. Traditional oil lifting ring rod bending and forming processes often employ natural gas flame heating. While this method is simple and easy to implement, it suffers from low heating efficiency, high heat loss, and uneven heating. Utility Model Content

[0003] The purpose of this invention is to provide a device for induction heating of the oil lifting ring rod, in order to solve the problems of low heating efficiency, large heat loss and uneven heating in the traditional oil lifting ring rod bending and forming process.

[0004] The technical solution of this utility model is: a device for induction heating of the oil lifting ring rod, including a lifting ring and an induction coil. The induction coil is C-shaped and has a heat insulation cover on the upper part. The heat insulation cover and the induction coil are consistent with the shape of the lifting ring rod and are symmetrically arranged on the upper and lower sides of the lifting ring rod. Rotary lifting mechanisms are symmetrically arranged on the left and right sides of the induction coil. The induction coil is provided with an inlet and an outlet respectively.

[0005] As a further improvement of this utility model, the two rotary lifting mechanisms include a first rotary lifting mechanism and a second rotary lifting mechanism. The first rotary lifting mechanism and the second rotary lifting mechanism have the same structure. The rotary lifting mechanism includes a drive motor, a cylinder support, a lifting cylinder, a lifting platform, a bearing seat, a drive roller, a drive chain, a driven roller, and a driven chain. The lifting cylinder is fixed on the cylinder support, and the lifting platform is raised and lowered by the lifting cylinder. The drive roller is rotated by the drive motor through the drive chain. The driven roller is rotated by the drive roller through the driven chain. The drive roller and the driven roller are fixed on the lifting platform by the bearing seat.

[0006] As a further improvement of this utility model, an insulating partition is provided at the bottom of the induction coil.

[0007] As a further improvement of this utility model, an induction coil support is provided at the bottom of the induction coil.

[0008] As a further improvement of this utility model, the bottom of the induction coil bracket and the two rotating lifting mechanisms are provided with guide rails.

[0009] As a further improvement of this utility model, the induction coil is equipped with an intelligent temperature control system.

[0010] As a further improvement of this utility model, the induction coil and the heat insulation cover are made of high-performance heat insulation materials.

[0011] The beneficial effects of this utility model are as follows: This invention cleverly mimics the shape of the lifting ring rod to create an induction coil and a heat insulation cover. The induction coil is C-shaped, which cleverly solves the problem of the lifting ring being large at both ends and thin in the middle, and being affected by the shape of the lifting ring.

[0012] This invention features an intelligent temperature control system that precisely controls the heating temperature, ensuring temperature stability during the bending and forming process of the rod.

[0013] This invention uses high-performance insulation materials to reduce heat loss and improve thermal efficiency. The device has an energy-saving design, reducing energy consumption by more than 30% compared to traditional natural gas heating methods.

[0018] like Figures 1-3As shown, a device for induction heating of the rod section of an oil lifting ring includes a lifting ring and an induction coil 3. The induction coil 3 is C-shaped and has a heat insulation cover 2 on its upper part. The heat insulation cover 2 and the induction coil 3 have the same shape as the rod section of the lifting ring 1 and are symmetrically arranged on the upper and lower sides of the rod section of the lifting ring 1. Rotary lifting mechanisms are symmetrically arranged on the left and right sides of the induction coil 3. The induction coil 3 is provided with an inlet 18 and an outlet 19 respectively.

[0019] The two rotary lifting mechanisms include a first rotary lifting mechanism 16 and a second rotary lifting mechanism 17. The first rotary lifting mechanism 16 and the second rotary lifting mechanism 17 have the same structure. The rotary lifting mechanism includes a drive motor 5, a cylinder support 6, a lifting cylinder 7, a lifting platform 10, a bearing seat 11, a drive roller 12, a drive chain 15, a driven roller 14, and a driven chain 13. The lifting cylinder 7 is fixed on the cylinder support 6. The lifting platform 10 is raised and lowered by the lifting cylinder 7. The drive roller 12 is rotated by the drive motor 5 through the drive chain 15. The driven roller 14 is rotated by the drive roller 12 through the driven chain 13. The drive roller 12 and the driven roller 14 are fixed on the lifting platform 10 by the bearing seat 11.

[0020] An insulating partition 4 is provided at the bottom of the induction coil 3. An induction coil support 9 is provided at the bottom of the induction coil 3. Guide rails 8 are provided at the bottom of the induction coil support 9 and the two rotating lifting mechanisms. The induction coil 3 is equipped with an intelligent temperature control system. The induction coil 3 and the insulation cover 2 are made of high-performance insulation material.

[0021] First, place the lifting ring 1 on the first rotating lifting mechanism 16 and the second rotating lifting mechanism 17. Adjust the center of the lifting ring 1 rod to coincide with the center of the induction coil 3. Adjust the two rotating lifting mechanisms to lift synchronously so that the lifting ring 1 rod is located in the middle of the induction coil 3. After adjusting the position, cover it with the heat preservation cover 2, start the two rotating lifting mechanisms to rotate synchronously, adjust the speed to 10 r / min, turn on the power of the induction coil 3, and start induction heating. At the same time, pass cooling water through the water inlet 18 of the induction coil 3 to ensure that the temperature of the induction coil 3 does not become too high during induction heating. After reaching the set temperature and maintaining the temperature for a certain period of time, turn off the power to stop heating, remove the heat preservation cover 2, the rotating lifting mechanism stops rotating, and rises synchronously to remove the lifting ring 1 from the induction coil 3, thus completing the heating of the lifting ring 1 rod.
