Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic drill boxes, in particular to a transmission device. Background Art

[0002] The downhole hydraulic-driven drill box is a core component in downhole drilling equipment. It utilizes the power transmission and conversion functions of the hydraulic system to provide necessary rotational force, propulsion force, etc. for the drill tool to complete the drilling task. This drill box realizes various functions of the drilling operation.

[0003] The existing downhole hydraulic-driven drill box is a traditional drill box with an up-and-down structure.

This structural method is simple, and internal water sealing failure is likely to occur. Under the action of the water filling pressure, it is very easy for water to enter the shaft seal, resulting in pollution and emulsification of the hydraulic oil inside the hydraulic system, reducing the service life.

[0027] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model.

[0034] During use, the staff starts the driving component 101, and the driving component 101 begins to operate. The driving component 101 drives the transmission component 102 to rotate. The rotation of the transmission component 102 drives the rotating component 201 to rotate. At this time, the hydraulic oil required by the driving component 101 flows into the driving component 101 through the liquid distribution block component 203, and the flushing water required after drilling flows into the rotating component 201 through the water distribution base component 203.

[0042] In summary, the beneficial effect of a transmission device is that through the cooperation of the driving gear 102b and the driven gear 201d, the driving force of the driving motor 101a can be transmitted to the flushing unit 200. Through the cooperation of the water distribution seat assembly 204 and the liquid distribution seat assembly 203, the hydraulic oil flows into the driving motor 101a through the liquid distribution seat assembly 203, the flushing water flows into the drill pipe through the water distribution seat assembly 204, the hydraulic oil is separated from the flushing water, and the hydraulic oil is no longer emulsified due to the pollution of the flushing water.

[0048] Further, the oil seal assembly 202 includes a hole snap ring (202a) disposed on the outside of the main shaft 201a, an oil seal seat 202b disposed on the outside of the hole snap ring 202a, and a rotating shaft sleeve 202c disposed on the top of the oil seal seat 202b.

Among them, the liquid distribution seat 203a is fixedly connected to the secondary liquid distribution block 203b, the hydraulic interface 203c is fixedly connected to the liquid distribution seat 203a, and the first waterway interface 203d is fixedly connected to the liquid distribution seat 203a.

[0050] Further, the water distribution seat assembly 204 includes a water distribution seat 204a disposed at the bottom of the secondary liquid distribution block 203b, a second waterway interface 204b disposed inside the water distribution seat 204a, and a water seal 204c disposed inside the water distribution seat 204a.

[0051] In use, the staff connect the drive motor 101a to a stable power supply and ensure that the voltage and current meet the equipment requirements. Connect the external flushing water source to the second waterway interface 204b of the water distribution seat assembly 204 through a pipeline, and check whether the hydraulic oil in the liquid distribution block assembly 203 of the transmission device is sufficient. Further, the staff press the start button of the drive motor 101a, and the drive motor 101a starts to work. The drive motor 101a drives the rotating shaft 101b inside the base 101a to rotate. The rotation of the rotating shaft 101b drives the driving gear 102b to rotate synchronously in the same direction. The rotation of the driving gear 102b drives the driven gear 201d to rotate synchronously in the same direction. The rotation of the driven gear 201d drives the main shaft 201a to rotate synchronously in the same direction. While the main shaft 201a is rotating, the flat key 201 and the lateral key 201c cooperate with each other to limit and fix the main shaft 201a, and the limit ring 201f limits the outside of the main shaft 201a. When drilling or after drilling is completed, the hydraulic oil flows into the drive assembly 101 through the hydraulic interface 203c of the liquid distribution block assembly 203. At the same time, the flushing water flows into the water distribution seat 204a through the second waterway interface 204b of the water distribution seat assembly 204. With the rotation of the main shaft 201a and the driven gear 201d of the rotating assembly 201, the flushing water is brought into the inside of the rotating assembly 201 to flush the drill dust inside the drill pipe and the drill bit. When the flushing is completed, the drive motor 101a is turned off.

[0052] In summary, the beneficial effect of a transmission device is that through the cooperation of the driving gear 102b and the driven gear 201d, the driving force of the drive motor 101a can be transmitted to the flushing unit 200. Through the cooperation of the water distribution seat assembly 204 and the liquid distribution seat assembly 203, the hydraulic oil flows into the drive motor 101a through the liquid distribution seat assembly 203, and the flushing water flows into the drill pipe through the water distribution seat assembly 204. The hydraulic oil is separated from the flushing water, so that the hydraulic oil is no longer emulsified by the pollution of the flushing water.
