Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. Among them, the directional nouns such as "left", "right", "front", and "back" mentioned herein are as follows: Figure 1 and Figure 2 The orientation is referenced.

[0036] like Figures 1-6As shown, this embodiment provides a hydraulic station for iron roughnecks, including a main frame 1, and a motor pump group 2, a fully enclosed oil tank 3, a radiator 4, an electric control box 8 and a control valve block 5 installed in the main frame 1; the height and the length in the front-to-back direction of the main frame 1 match the height and length of the fully enclosed oil tank 3, the radiator 4, the electric control box 8 and the motor pump group 2 are located on one side of the fully enclosed oil tank 3, and the necessary pipeline connection space is reserved. The radiator 4 and the electric control box 8 are located above the motor pump group 2, and the installation height of the radiator 4 is less than the height of the fully enclosed oil tank 3. The height of the enclosed oil tank 3 and the installation height of the electrical control box 8 are the same as those of the fully enclosed oil tank 3. The width of the radiator 4 is greater than that of the electrical control box 8, and the left-right length of the main frame 1 matches the combined widths of the radiator 4 and the fully enclosed oil tank 3. The oil inlet and return port of the motor pump unit 2 are connected to the fully enclosed oil tank 3, while the oil outlet of the motor pump unit 2 is connected to the oil inlet of the control valve block 5, which is connected to the iron roughneck. The oil return port of the control valve block 5 is connected to the oil inlet of the radiator 4, while the oil outlet of the radiator 4 is connected to the fully enclosed oil tank 3. The operation display interface of the electrical control box 8 faces forward. The electrical control box 8 connects the motor pump unit 2 and the radiator 4. The electrical control box 8 contains control knobs for the motor pump unit 2 and the radiator 4, which can start and stop the motor pump unit 2 and the radiator 4. It is also equipped with a hydraulic station power status light to visually monitor the operating status of the equipment.

[0037] Specifically, the fully enclosed oil tank 3, radiator 4, motor pump unit 2, and control valve block 5 are integrated within a main frame 1. The radiator 4 and motor pump unit 2 are arranged vertically on one side of the fully enclosed oil tank 3 to form the main structure. The main frame 1 is generally rectangular in shape, with its length and height matching those of the fully enclosed oil tank 3, and its width matching the combined widths of the radiator 4 and fully enclosed oil tank 3. Thus, the dimensions of the main frame 1 match the space occupied by the main structure, achieving a compact internal layout and a compact overall structure. It should be noted that the dimensions of the main frame described above refer to the dimensions of the space within the main frame. The hydraulic system, consisting of the fully enclosed oil tank 3, radiator 4, motor pump unit 2, and control valve block 5, supplies oil to the iron roughneck, meeting the needs of the iron roughneck. Compared to existing technologies, this hydraulic station does not occupy excessive drilling floor space, reduces impact on other drilling floor equipment, and improves safety. It also meets the needs of iron roughneck operators, simplifies the overall structure, and reduces maintenance difficulties, thus possessing great potential for widespread adoption.

[0038] Furthermore, if Figure 2-Figure 4As shown, the motor-pump assembly 2 includes a drive motor 21 and a plunger pump 22. The drive motor 21 is mounted within the main frame 1 and is in transmission connection with the plunger pump 22. The plunger pump 22's oil inlet and return ports are connected to the fully enclosed oil tank 3, while its oil outlet is connected to the oil inlet of the control valve block 5. The plunger pump 22 also has a load-sensing line connected to the control valve block 5 to detect load pressure. The control valve block 5 is equipped with an oil return port and two hydraulic connections. These ports connect the control valve block 5 to the iron roughneck to meet the roughneck's hydraulic needs. In this embodiment, the plunger pump 22's oil inlet is connected to the fully enclosed oil tank 3 via an oil suction filter 6. The radiator 4's oil outlet is connected to the fully enclosed oil tank 3 via an oil return filter 7. The radiator 4 is located above the drive motor 21, and the height of the drive motor 21 defines the height of the motor-pump assembly 2.

[0039] Further, if Figure 5 As shown, the fully enclosed fuel tank 3 includes a main tank 31, a sub-tank 32, a breathing capsule 33, and an air filter 34. The sub-tank 32 is located at the top of the main tank 31 and is connected to the top of the main tank 31. The breathing capsule 33 is located inside the sub-tank 32 and is connected to the outside atmosphere through the air filter 34. The hydraulic oil in the main tank 31 does not exceed three-quarters of its capacity. The sub-tank 32 is connected to the top of the main tank 31, that is, the cavity above the hydraulic oil. Under normal circumstances, the hydraulic oil does not enter the sub-tank 32, so the breathing capsule 33 inside the sub-tank 32 is completely isolated from the hydraulic oil. The main tank 31 and the sub-tank 32 exchange media only through the air initially contained within them. This allows the breathing capsule 33 to always contract and expand in a favorable environment. This prevents contamination and oxidation of the hydraulic oil by dust and moisture in the air, greatly extending the replacement cycle and service life of the hydraulic oil. In this specific embodiment, the height of the fully enclosed fuel tank 3 is the sum of the heights of the main fuel tank 31 and the auxiliary fuel tank 32 , and the length and width of the fully enclosed fuel tank 3 are the length and width of the main fuel tank 31 .

[0040] Furthermore, in this specific embodiment, the auxiliary fuel tank 32 is provided with a safety valve to discharge the gas in the auxiliary fuel tank 32 when the breathing capsule 33 fails, thereby avoiding damage to components caused by excessive pressure in the main fuel tank 31.
