[0002] During the transportation of oil extraction drilling steel pipes, the threads at the ends of the steel pipes need to be protected. Therefore, protective rings need to be screwed onto both ends of the steel pipes. Currently, existing steel mills use manual screwing methods during the screwing process of the protective rings. This screwing method has problems such as high manual labor intensity, slow screwing speed, low screwing quality, and low screwing qualification rate.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figure 1-2 , a new type of connector screwing machine in this embodiment includes a main clamp assembly 1, a back clamp 4, a control console 5 and a guide rail 6. A connecting plate 11 is provided on the main clamp assembly 1. A mounting bracket 12 is provided on the top of the connecting plate 11. A plurality of planetary clamps 13 are rotatably connected to the mounting bracket 12. Linkage gears 131 are provided on each of the plurality of planetary clamps 13. A protection housing 14 is provided on the mounting bracket 12. A transmission component 3 is rotatably arranged inside the protection housing 14. The transmission component 3 is in transmission connection with the plurality of linkage gears 131. Two transmission chambers 141 are provided on the front surface of the protection housing 14. A first hydraulic motor 15 and a second hydraulic motor 16 are respectively provided on the two transmission chambers 141. A gear set 2 is rotatably connected to the middle of the protection housing 14. The gear set 2 is in transmission connection with the transmission component 3 inside the protection housing 14. A first hydraulic connection port 151 and a second hydraulic connection port 152 are provided on the first hydraulic motor 15. A third hydraulic connection port 161 and a fourth hydraulic connection port 162 are provided on the second hydraulic motor 16. Driving gears are provided on the output shafts of the first hydraulic motor 15 and the second hydraulic motor 16. The driving gears are in transmission connection with the gear set 2.

[0025] As a preferred technical solution in this embodiment, when the staff needs to use low torque, such as fixing the oil pipe, the liquid can be made to enter the interior of the first hydraulic motor 15 by controlling the first hydraulic connection port 151 on the first hydraulic motor 15, so that the output shaft of the first hydraulic motor 15 can drive the drive gear to rotate. During the rotation of the drive gear, the gear set 2 can be driven to rotate. During the rotation of the gear set 2, the transmission assembly 3 can be driven to rotate. During the rotation of the transmission assembly 3, a plurality of linkage gears 131 can be driven to rotate. During the rotation of the linkage gears 131, the planetary clamp 13 can be effectively driven to rotate, thereby realizing the clamping and fixing effect on the oil pipe;

[0026] When it is necessary to connect the protective ring to both ends of the oil pipe, that is, when high torque is required, the liquid can be injected into the second hydraulic motor 16 through the third hydraulic connection port 161, thereby driving the drive gear provided on the output shaft of the second hydraulic motor 16 to rotate. During the rotation of the drive gear, the gear set 2 can be driven to rotate. At this time, the gear set 2 is subjected to the forces applied by the two drive gears, thereby effectively ensuring the effect of increasing its torque and ensuring the effective connection effect between the protective ring and the oil pipe during its use. Similarly, when it is necessary to disassemble the protective ring, the liquid can be injected into the first hydraulic motor 15 and the second hydraulic motor 16 through the fourth hydraulic connection port 162 and the second hydraulic connection port 152, thereby ensuring the effective disassembly effect on the protection during its use. When resetting is required, only by injecting the liquid into the second hydraulic motor 16 through the fourth hydraulic connection port 162, the second hydraulic motor 16 can drive the drive gear connected to the output shaft to achieve the reset effect of the linkage gear 131.

[0027] This connection method can effectively achieve the effect of adjustable torque during use, ensuring that the torque can be controlled according to different use requirements during its use, effectively increasing its flexibility during use, ensuring that it can adapt to various different working environments, effectively increasing its use effect, and avoiding the situation of accelerating the damage of components due to the use of a fixed torque for a long time.

[0028] Embodiment Two:

[0029] Please refer to Figure 3-5, To achieve a good linkage effect, in this embodiment, the connecting plate 11 is slidably connected to the guide rail 6. A connecting block 17 is fixedly connected to the bottom of the connecting plate 11, and a transmission wheel 18 is arranged on the connecting block 17. A transmission gear 21 is arranged on the gear set 2, and a driven gear 22 is fixedly connected to the transmission gear 21. The transmission gear 21 remains meshed with the driving gear. A transmission disc 31 is arranged on the transmission assembly 3, and a transmission gear ring 32 and a linkage gear ring 33 are fixedly connected to the transmission disc 31. The transmission gear ring 32 remains meshed with the driven gear 22. The linkage gear ring 33 remains meshed with a plurality of linkage gears 131.

[0030] As a preferred technical solution in this embodiment, during actual use, when the staff drives the gear set 2 to rotate by controlling the first hydraulic motor 15 or the second hydraulic motor 16, both the transmission gear 21 and the driven gear 22 arranged on the gear set 2 can rotate. During the rotation of the driven gear 22, it can drive the transmission gear ring 32 to rotate. During the rotation of the transmission gear ring 32, it can drive the transmission disc 31 to rotate. During the rotation of the transmission disc 31, it can drive the linkage gear ring 33 to rotate. During the rotation of the linkage gear ring 33, it can drive the linkage gears 131 to rotate, so that the linkage gears 131 can drive the planetary clamp 13 to achieve the rotation effect.

[0031] The working principle of the above embodiment is as follows:

[0032] 1. When the staff needs to use low torque, such as fixing the oil pipe, the liquid can enter the interior of the first hydraulic motor 15 by controlling the first hydraulic connection port 151 on the first hydraulic motor 15, so that the output shaft of the first hydraulic motor 15 can drive the driving gear to rotate. During the rotation of the driving gear, it can drive the gear set 2 to rotate. During the rotation of the gear set 2, it can drive the transmission assembly 3 to rotate. During the rotation of the transmission assembly 3, it can drive a plurality of linkage gears 131 to rotate. During the rotation of the linkage gears 131, it can effectively drive the planetary clamp 13 to rotate, so as to achieve the clamping and fixing effect of the oil pipe;

[0033] When it is necessary to connect the protective ring to both ends of the oil pipe, that is, when high torque is required, the liquid can be injected into the second hydraulic motor 16 through the third hydraulic connection port 161, so as to drive the driving gear arranged on the output shaft of the second hydraulic motor 16 to rotate. During the rotation of the driving gear, it can drive the gear set 2 to rotate. At this time, the gear set 2 is subjected to the forces applied by the two driving gears, so as to effectively ensure the effect of increasing its torque and ensure the effective connection effect between the protective ring and the oil pipe during its use.

[0034] II. During actual use, when the staff drives the gear set 2 to rotate by controlling the first hydraulic motor 15 or the second hydraulic motor 16, both the driving gear 21 and the driven gear 22 provided on the gear set 2 can rotate. During the rotation of the driven gear 22, it can drive the transmission gear ring 32 to rotate. During the rotation of the transmission gear ring 32, it can drive the transmission disc 31 to rotate. During the rotation of the transmission disc 31, it can drive the linkage gear ring 33 to rotate.
