[0047] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0048] Example 1

[0049] like Figure 1-7 As shown, this embodiment provides a cleaning device for cleaning and oiling a drill pipe 3, including an adjustment assembly and a working assembly, one end of the adjustment assembly is arranged on the drilling platform, and the other end is connected to the working assembly. The working assembly includes a cleaning device 1 and a blowout prevention device 2. When cleaning the drill pipe 3, the adjustment assembly is connected to the cleaning device 1, and when disassembling the drill pipe 3, the adjustment assembly is connected to the blowout prevention device 2.

[0050] Specifically, the thread cleaning device 1 includes a thread cleaning device base 11, and a thread brushing assembly 12 and a thread oiling assembly 13 arranged on the thread cleaning device base 11. The adjusting assembly can drive the thread brushing assembly to move in a circle around the axis of the drill rod 3, so that the thread brushing assembly 12 can clean both the external thread and the internal thread. While the adjusting assembly drives the thread brushing assembly 12 to move in a circle around the drill rod 3, the thread brushing assembly 12 also maintains a self-rotating state. Therefore, the thread brushing assembly 12 in this embodiment drives the revolution driven by the adjusting assembly and its own self-rotation to achieve the cleaning of the external thread and the internal thread, so that one brush can be used for two purposes. Similarly, the adjusting assembly can also drive the thread oiling assembly 13 to dip the thread oil in the thread oil barrel arranged on the drilling platform, and then drive the thread oiling assembly 13 to move in a circle around the axis of the drill rod 3, so that the thread oiling assembly 13 also has the effect of one brush for two purposes, and can apply thread oil to both the external thread and the internal thread.

[0051] like Figure 1 As shown, the adjustment assembly specifically includes a connecting base 4 and a robotic arm. The connecting base 4 is arranged on the drilling platform, and the lower end of the robotic arm is fixedly arranged on the connecting base 4 by bolts, and the robotic arm is connected to the working assembly. In this embodiment, the robotic arm is preferably a six-axis robotic arm 5. In this embodiment, the six-axis robotic arm 5 drives the brush thread assembly to move in a circle around the axis of the drill rod 3 under the control of the electric control system 6. Similarly, the six-axis robotic arm 5 also drives the thread oiling assembly 13 to dip in the thread oil, and drives the thread oiling assembly 13 to move in a circle around the axis of the drill rod 3. The six-axis robotic arm 5 has a high degree of freedom and can flexibly control the movement trajectory of the brush thread assembly 12 and the thread oiling assembly 13.

[0052] Preferably, the front end of the six-axis robot arm 5 can be fixedly provided with a first connection component by bolts or the like, and the second connection component can also be provided on the cleaning buckle base 11 and the blowout prevention device 2 by bolts or pins or the like, and the first connection component and the second connection component are detachably connected, so that the cleaning buckle device 1 or the blowout prevention device 2 can be fixedly provided on the front end surface of the six-axis robot arm 5. Furthermore, the first connection component and the second connection component are preferably a quick-change structure 10 or a manual connection seat 9.

[0053] like Figure 2As shown, the button cleaning device in this embodiment also includes a tool placement rack, which includes a tool base frame 7 and a placement rack 8. In this embodiment, the tool placement rack is used to provide a placement position for the button cleaning device 1 and the blowout prevention device 2, so as to facilitate the alternating use of the button cleaning device 1 and the blowout prevention device 2 during cleaning and thread oiling. Specifically, the tool base frame 7 is fixedly arranged on the drilling platform by bolts, etc., and the placement rack 8 can be fixedly connected to the tool base frame 7 by bolts, etc. The button cleaning device 1 and the blowout prevention device 2 can be placed on the placement rack 8 by positioning members, including but not limited to positioning pins, etc.

[0054] When the first connection component and the second connection component use the quick-change structure 10 controlled by the air circuit, the base 11 of the cleaning clip or the blowout prevention device 2 can be quickly and automatically connected or automatically separated from the six-axis robot arm 5. The quick-change structure 10 not only enables the cleaning clip device 1 and the blowout prevention device 2 to be quickly and automatically connected to the quick-change structure 10 on the six-axis robot arm 5, but also enables the cleaning clip device 1 and the blowout prevention device 2 to be quickly and automatically moved to the corresponding position of the tool placement rack under the control of the six-axis robot arm 5 and separated from the six-axis robot arm 5, and safely and stably placed on the tool placement rack for standby use.

[0055] However, the cost of realizing automatic switching of the quick-change structure 10 is relatively high. In order to further reduce the cost of the equipment, the first connecting assembly and the second connecting assembly in this embodiment can also use a manual connecting seat 9. The manual connecting seat 9 needs to manually install the cleaning buckle device 1 or the blowout prevention device 2 to the front end of the six-axis robot arm 5, or after the six-axis robot arm 5 places the cleaning buckle device 1 or the blowout prevention device 2 on the tool placement rack, the cleaning buckle device 1 or the blowout prevention device 2 is separated from the six-axis robot arm 5.

[0056] like Figure 3-5 As shown, the brush thread assembly 12 includes a bearing bin 121, a transmission shaft 122, an air motor 123 and a thread brush 124. The bearing bin 121 can be fixedly arranged on the button cleaner base 11 by bolts, etc., the air motor 123 is fixedly arranged on the bearing bin 121 by bolts, etc., the transmission shaft 122 is arranged inside the bearing bin 121, and both ends of the transmission shaft 122 are respectively connected to the output shaft of the air motor 123 and the thread brush 124.

[0057] The thread brush 124 is a round brush, which is driven to rotate by a transmission shaft 122 connected to an air motor 123. The bristle edge of the round brush can contact the external thread or internal thread of the drill tool during the rotation process. At the same time, the rotating round brush moves in a circle around the axis of the drill tool under the drive of the six-axis robot arm 5, increasing the pressure between the round brush and the thread, thereby removing the sludge, rust, etc. on the thread. Therefore, the thread brush 124 can orbit around the axis of the drill rod under the drive of the six-axis robot arm 5. Under the combined effect of the revolution of the thread brush 124 around the external thread or internal thread of the drill rod and the rotation of the thread brush 124, the bristle edge of the thread brush 124 contacts the external thread or internal thread of the drill rod and generates relative motion, so that the bristle track of the thread brush 124 can cover the entire thread area of ​​the drill rod, thereby removing the sludge, rust, etc. on the thread of the drill rod. Driven by the six-axis robot arm 5, the brush thread assembly 12 can rotate along the outer side of the external thread of the drill to clean the external thread, and can also narrow the range and rotate within the area where the internal thread of the drill is located to clean the internal thread.

[0058] Therefore, the thread brushing assembly 12 in this embodiment revolves around the axis of the drill pipe through the six-axis robotic arm 5, and cooperates with its own rotation to achieve the cleaning of the external thread and the internal thread, so that one brush can serve two purposes. There is no need to separately set up a bulky and complicated thread brushing assembly and an internal thread brushing assembly, which reduces the burden on the equipment.

[0059] Furthermore, in order to prevent the oil sludge, rust and the like removed from the drill pipe thread by the thread brush 124 from splashing to the area outside the screw cleaner base 11 and causing pollution, the thread brush 124 is also arranged inside the screw cleaner base 11 in this embodiment, and a vertical enclosure 125 is arranged on the screw cleaner base 11, so that the screw cleaner base 11 forms a semi-enclosed structure without a cover. Preferably, the bottom plate of the screw cleaner base 11 is circular, and the enclosure 125 and the bottom plate form a cylinder without a cover.

[0060] The thread oiling assembly 13 includes an oiling brush base 131 and an oiling brush 132. The oiling brush base 131 is fixedly arranged on the button cleaning device base 11, and the oiling brush 132 is fixedly connected to the oiling brush base 131. The angle between the oiling brush 132 and the thread brush 124 can be set arbitrarily, preferably 180°.

[0061] The six-axis robot arm 5 can also be used to switch between the thread brushing assembly 12 and the thread oil applying assembly 13. Specifically, after the six-axis robot arm 5 drives the thread brushing assembly 12 to revolve and the thread brushing assembly 12 to rotate and complete the cleaning work of the above-mentioned drill pipe thread, the six-axis robot arm 5 will drive the thread oil applying assembly 13 to flip 180°, and flip the thread oil applying assembly 13 to one end of the thread to be coated with thread oil, so as to achieve alternating cleaning and blowout prevention functions.

[0062] The oiling brush 132 is also a round brush. Driven by the six-axis robot 5, the thread oiling assembly 13 first moves to the thread oil barrel set on the drilling platform, so that the oiling brush 132 is dipped in thread oil, and then the oiling brush 132 is driven to enter the internal thread hole of the drill pipe and make a circular motion around the axis of the drill pipe, and the thread oil is applied to the internal thread of the drill tool, thereby achieving the oiling work of the internal thread of the drill tool. Similarly, driven by the six-axis robot 5, the oiling brush 132 can also make a circular motion around the axis of the external thread of the drill pipe and on the outside of the drill pipe, and the thread oil is applied to the external thread of the drill tool, thereby achieving the oiling work of the external thread of the drill tool.

[0063] Therefore, in this embodiment, the six-axis robot arm 5 can drive the thread oiling assembly 13 to dip into the thread oil in the thread oil barrel set on the drilling platform, and then drive the thread oiling assembly 13 to move in a circle around the axis of the drill pipe, so that the thread oiling assembly 13 can apply thread oil to both the external thread and the internal thread, and also has the effect of one brush for two purposes. In addition, in this embodiment, a thread oil barrel can be directly set on the drilling platform, without the need to set up complex oil pipelines, oil injection switches, and electromagnetic valves that control the amount of oil sprayed, as in the prior art, and even more without the need to set up a large oil-throwing assembly.

[0064] like Figure 6-7 As shown, the blowout prevention device 2 in this embodiment includes a box assembly 21 and a mounting frame assembly 22, and the box assembly 21 is arranged on the mounting frame assembly 22. When the drill pipe column is just loosened, the box assembly 21 is used to buckle on the joint thread part to cover the drill pipe joint, so as to prevent the mud and other drilling fluids in the drill pipe from overflowing and contaminating the drilling platform when the joint thread of the lifted drill pipe is removed. The second connecting assembly is fixedly arranged on the mounting frame assembly 22 by bolts, etc. When the drill pipe is disassembled, the mounting frame assembly 22 is detachably connected to the manual connecting seat 9 or the quick-change structure 10 on the six-axis robot arm 5, so as to facilitate the rapid disassembly and assembly of the blowout prevention device 2.

[0065] The box assembly 21 includes a first box 211 and a second box 212 arranged in pairs. The first box 211 and the second box 212 are specifically the same semi-cylindrical shell structure. The first box 211 and the second box 212 can form a hollow cylinder with openings at both ends when spliced.

[0066] The opening and closing of the first box body 211 and the second box body 212 are realized by the clamping cylinder 23. Specifically, in this embodiment, two groups of clamping cylinders 23 are provided, which are respectively located at the upper end and the lower end of the first box body 211. The two ends of the clamping cylinder 23 are respectively hinged to the first box body 211 and the second box body 212. The opening and closing of the first box body 211 and the second box body 212 are realized by the extension and retraction of the clamping cylinder 23. When the clamping cylinder 23 extends outward, the first box body 211 and the second box body 212 are closed and docked to form a cylindrical shell with two ends opened, and the box body assembly 21 is in a closed state. When the clamping cylinder 23 retracts inward, the box body assembly 21 is in an open state.

[0067] An axial sealing strip 24 is provided on an axial side of the first box body 211 or the second box body 212 away from the clamping cylinder 23. When the box body assembly 21 is in a closed state, the axial sealing strip 24 seals the butt edge of the first box body 211 and the second box body 212 to further improve the sealing performance of the blowout preventer 2.

[0068] Furthermore, end face sealing rings 25 are respectively provided at the two semicircular end faces of the first box body 211 and the second box body 212. When the box body assembly 21 is in a closed state, the end face sealing rings 25 on the first box body 211 and the second box body 212 can contact the drill pipe to form a sealing structure to prevent the drilling fluid from leaking from the upper end and the lower end of the box body assembly 21. Specifically, an opening is provided on the end face sealing ring 25, and the end face sealing ring 25 is fixedly provided on the first box body 211 and the second box body 212 by an end face sealing fixing pin 26. The end face sealing fixing pin 26 specifically includes a pin shaft and a spring. The pin shaft of the end face sealing fixing pin 26 fixes the end face sealing ring 25 to the first box body 211 and the second box body 212 respectively through the opening on the end face sealing ring 25. When the end face sealing ring 25 needs to be replaced, the operator manually pulls up the end face sealing fixing pin 26 to replace the end face sealing ring 25. After the replacement is completed, the end face sealing fixing pin 26 can be reset under the action of the spring.

[0069] The anti-blowout device 2 is also provided with a lock buckle structure, which specifically includes a lock handle cylinder 27, a lock handle 28 and a lock tongue 29. The lock handle cylinder 27 is connected to the second box body 212 through a pin, the lock handle 28 is connected to the second box body 212 through a pin, and the other end of the lock handle cylinder 27 is connected to the lock handle 28 through a pin. The lock tongue 29 is provided on the first box body 211. When the box body assembly 21 is in a closed state, the lock handle cylinder 27 extends, driving the end of the lock handle 28 to be close to the first box body 211, and then locked with the lock tongue 29 provided on the first box body 211, locking the first box body 211 and the second box body 212 together, so that the closing of the box body assembly 21 is more tight and reliable.

[0070] When the drill pipe column is just loosened, the box assembly 21 is buckled on the threaded part of the joint, so that the drilling fluid in the upper drill pipe column flows into the box assembly 21 and flows into the drilling fluid circulation system through the lower outlet, preventing the drilling fluid from overflowing and contaminating the drilling platform when the joint threads are loosened.

[0071] The above embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
