Description

Technical Field

[0001] This utility model relates to the field of automatic drill rod technology, specifically to an automatic drill rod brush thread machine. Background Technology

[0002] As an important well-drilling tool, the quality of drill pipe is receiving increasing attention, which presents new challenges for drill pipe manufacturers. To date, the method for applying oil to drill pipe threads has always involved wellhead workers grabbing an oil brush, dipping it in an oil container, and then applying it to the drill pipe threads.

[0003] Application number CN201310455499.0 discloses a drill pipe thread oiling machine, including an oil tank and an oiler. An oil outlet pipe is inserted into the upper end of the oil tank, and an oil delivery pipe is connected to the end of the oiler. The oil outlet pipe and the oil delivery pipe are connected by a flexible conveying hose. This invention has a simple structure and advantages such as fast oiling speed, uniform oiling, convenient operation, easy maintenance, no need for power supply, and high safety factor.

[0004] However, the device lacks the operation of evenly applying oil to the threads. It only delivers oil into the female thread and cannot completely distribute the oil in the gap between the threads and the female thread. Therefore, an automatic drill rod brush thread machine is proposed, which allows the brush on the inside of the curved plate to apply oil to the surface of the threads, and allows the oil to be evenly applied to the outside of the threads. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an automatic drill rod brush thread machine, which allows the brush on the inner side of the arc plate to apply oil to the surface of the thread, and allows the oil to be evenly applied to the outer side of the thread.

[0006] The technical solution adopted by this utility model to solve its technical problem is an automatic drill rod brush thread machine, including an oiler. An arc-shaped plate is movably installed inside the oiler. Two arc-shaped plates are arranged opposite each other. Brushes are provided on the side of the two arc-shaped plates that are close to each other. The top of the two arc-shaped plates is fixedly connected to the bottom of a connecting block. The connecting block is an inverted L-shaped box structure. The other end of the connecting block is fixedly connected to one end of a telescopic tube. Two telescopic tubes are arranged opposite each other. The two telescopic tubes are movably inserted into the two ends of a tee pipe.

[0007] The interior of the telescopic tube is connected to the interior of the tee tube. An oil injector is fixedly installed on the lower part of one side of the telescopic tube. The oil injector is connected to the interior of the telescopic tube. The top end of the tee tube is rotatably connected to the bottom end of the connector. The top end of the connector is fixedly connected to one end of the delivery hose. The other end of the delivery hose is located inside the oil tank.

[0008] By adopting the above technical solution, the oiler is fitted onto the drill rod threads, and two arc-shaped plates are clamped between the sides of the drill rod threads. The oil sprayer sprays oil into the gap between the arc-shaped plates and the drill rod threads. The oiler is then manually rotated, causing the arc-shaped plates to rotate. This allows the brush on the inner side of the arc-shaped plates to evenly apply oil to the outer side of the drill rod threads, thereby improving the coverage of the thread oil.

[0009] Specifically, the two curved plates are fixedly connected to one end of a connecting rod on opposite sides. There are two connecting rods, and the opposite ends of the two connecting rods pass through the oiler and are fixedly connected to one side of a limiting plate. There are two limiting plates.

[0010] Specifically, both limiting plates are located on the outside of the oiler, and pull rings are fixedly connected to the sides of the two limiting plates that are far apart from each other.

[0011] By adopting the above technical solution, pulling the pull ring can drive the two limiting plates to be pulled away from each other, thereby driving the two arc-shaped plates to move away from each other through the connection of the connecting rod. Then, the oiler is put on the drill rod thread and the drill rod thread is positioned between the two arc-shaped plates.

[0012] Specifically, springs are fitted onto the outer sides of both connecting rods. One end of each spring is fixedly connected to the inner side of the oiler, and the other end of each spring is fixedly connected to the outer side of the arc-shaped plate.

[0013] By adopting the above technical solution, when the pull ring is released, the two arc-shaped plates move closer to each other through the elastic force of the spring, thereby clamping the drill rod threads. This operation can be used to clamp and apply oil to drill rod threads of different diameters.

[0014] Specifically, a bearing is sleeved on the outer side of the connector, the bearing is installed inside the top of the oiler, and the connector is rotatably connected to the oiler through the bearing.

[0015] By adopting the above technical solution, the installation of the bearing allows the oiler to be rotatably connected to the connector, thus facilitating the rotation operation of the oiler.

[0016] Specifically, a manual control valve is sleeved on the outside of the delivery hose, and a pressure regulating valve is fixedly installed on the top of the oil tank.

[0017] By adopting the above technical solution, opening the manual control valve allows the oil in the delivery hose to be delivered into the tee pipe, and activating the pressure regulating valve allows the oil in the oil tank to be pressurized into the delivery hose for delivery.

[0018] The beneficial effects of this utility model are:

[0019] (1) The automatic drill rod thread brushing machine of this utility model is made by putting an oiler on the drill rod thread and clamping the side of the drill rod thread with two arc plates. The oil spraying head sprays oil into the gap between the arc plates and the drill rod thread. The oiler is manually rotated to make the oiler drive the arc plates to rotate, so that the brush on the inside of the arc plates can evenly apply the oil to the outside of the drill rod thread, thereby improving the coverage of the thread oil.

[0020] (2) The automatic drill rod thread brushing machine of this utility model can pull the two arc plates away from each other and use the spring to reset the arc plates to clamp the drill rod threads. At the same time, the oil spray head moves synchronously with the arc plate through the connecting block, so that the oil spray head is always located directly above the inner side of the arc plate, which can be adapted to the oiling operation of drill rod threads of different diameters.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] In order to allow the brush on the inner side of the curved plate to apply oil to the surface of the threads, and to ensure that the oil is evenly applied to the outer side of the threads, as an embodiment of this utility model, such as... Figures 1-3As shown, the automatic drill rod brush thread machine of this utility model includes an oiler 11. An arc-shaped plate 5 is movably installed inside the oiler 11. Two arc-shaped plates 5 are arranged opposite each other. A brush 6 is provided on the side of the two arc-shaped plates 5 that is close to each other. The top of the two arc-shaped plates 5 is fixedly connected to the bottom of the connecting block 3. The connecting block 3 is an inverted L-shaped box structure. The other end of the connecting block 3 is fixedly connected to one end of the telescopic tube 2. Two telescopic tubes 2 are arranged opposite each other. The two telescopic tubes 2 are respectively movably inserted into the two ends of the three-way pipe 1.

[0028] The interior of the telescopic pipe 2 is connected to the interior of the three-way pipe 1. An oil injector 4 is fixedly installed on the lower side of one side of the telescopic pipe 2. The oil injector 4 is connected to the interior of the telescopic pipe 2. The top end of the three-way pipe 1 is rotatably connected to the bottom end of the connector 13. The top end of the connector 13 is fixedly connected to one end of the delivery hose 12. The other end of the delivery hose 12 is located inside the oil tank 16.

[0029] When in use, the oiler 11 is fitted onto the drill rod thread, and the oil is sprayed from the spray nozzle 4 into the gap between the arc plate 5 and the drill rod thread. The operator only needs to manually rotate the oiler 11. The rotation of the oiler 11 can drive the arc plate 5 to rotate together through the connecting rod 9, so that the brush 6 on the inner side of the arc plate 5 can evenly apply oil to the drill rod thread.

[0030] It should be noted that the oil injector 4 is installed at the inner side and directly above the arc plate 5, so that the oil can be sprayed into the gap between the arc plate 5 and the drill rod thread.

[0031] This utility model also includes that the two arc-shaped plates 5 are fixedly connected to one end of a connecting rod 9 on opposite sides. There are two connecting rods 9, and the opposite ends of the two connecting rods 9 pass through the oiler 11 and are fixedly connected to one side of a limiting plate 8. There are two limiting plates 8.

[0032] This utility model also includes two limiting plates 8 located on the outside of the oiler 11, and pull rings 7 fixedly connected to the sides of the two limiting plates 8 that are far apart from each other.

[0033] In use, by pulling the pull ring 7, the two limiting plates 8 can be pulled away from each other, thereby driving the two arc plates 5 away from each other through the connection of the connecting rod 9. Then, the oiler 11 is put on the drill rod thread and the drill rod thread is positioned between the two arc plates 5.

[0034] It should be noted that since the top of the arc plate 5 is fixedly connected to the telescopic tube 2 through the connecting block 3, the telescopic tube 2 will also be stretched out from one end of the three-way tube 1 when the arc plate 5 is pulled, keeping pace with the movement of the arc plate 5, thereby ensuring that the injection position of the fuel injector 4 is always located directly above the inner side of the arc plate 5.

[0035] This utility model also includes that springs 10 are sleeved on the outer sides of both connecting rods 9, one end of the spring 10 is fixedly connected to the inner side of the oiler 11, and the other end of the spring 10 is fixedly connected to the outer side of the arc plate 5.

[0036] When in use, release the pull ring 7, and the two arc-shaped plates 5 will move closer to each other through the elastic force of the spring 10, thereby clamping the drill rod threads. This operation can be used to clamp and apply oil to drill rod threads of different diameters.

[0037] The present invention also includes a bearing 14 sleeved on the outer side of the connector 13, the bearing 14 being installed inside the top end of the oiler 11, and the connector 13 being rotatably connected to the oiler 11 through the bearing 14.

[0038] During use, the installation of bearing 14 allows the oiler 11 to be rotatably connected to connector 13, thus facilitating the rotation operation of the oiler 11.

[0039] This utility model also includes a manual control valve 15 sleeved on the outside of the delivery hose 12, and a pressure regulating valve 17 fixedly installed on the top of the oil tank 16.

[0040] In use, opening the manual control valve 15 allows the oil in the delivery hose 12 to be delivered into the tee pipe 1, and activating the pressure regulating valve 17 allows the oil in the oil tank 16 to be pressurized into the delivery hose 12 for delivery.

[0041] It should be noted that the pressure regulating valve 17 has an internal air pipe for easy air pressure adjustment, and the top of the oil tank 16 also has a sealing port for easy pouring of threaded oil.

[0042] When using this invention, to apply oil to the drill rod threads, first pull the pull ring 7 connected to the outer side of the two limiting plates 8. The two limiting plates 8 are pulled away from each other, thereby causing the two arc-shaped plates 5 to move away from each other through the connection rod 9. Then, put the oiler 11 on the drill rod threads, positioning the drill rod threads between the two arc-shaped plates 5. Then, release the pull ring 7, and the two arc-shaped plates 5 will move closer together through the elastic force of the spring 10, thus clamping the drill rod threads. Then, fill the oil tank 16 with thread oil, connect the air source, and open the pressure regulating valve 17 to allow the oil to flow. Oil in tank 16 enters delivery hose 12 for delivery. Manual control valve 15 is opened, allowing oil in delivery hose 12 to enter T-pipe 1 through connector 13. Then, the oil flows into telescopic pipes 2 at both ends of T-pipe 1 and finally sprays out from nozzle 4. At this time, the oil drips into the gap between the arc plate 5 and the drill rod thread. The operator only needs to manually rotate oil applicator 11. The rotation of oil applicator 11 can drive the arc plate 5 to rotate together through connecting rod 9, so that the brush 6 on the inner side of arc plate 5 can evenly apply oil to the drill rod thread.
