Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe cleaning, in particular to an oil pipe cleaning drilling tool. Background Art

[0002] A gas layer is a natural gas reservoir, usually located in an underground coal seam, and is composed of natural gas adsorbed in the coal seam. A gas layer is a very important natural gas resource, with advantages such as large reserves, wide distribution, and low mining costs. The formation of a gas layer is due to the combined effects of geological and biological effects, and the mining of a gas layer cannot be separated from oil pipes, so oil pipe cleaning drilling tools are indispensable equipment.

[0003] The patent with publication number CN212370742U discloses a cleaning drill tool for coalbed methane oil pipes, which includes a plate, both sides of the top surface of the bottom plate are fixedly connected to support plates, one side of the top of the support plate is rotatably connected to an active roller, and the other side of the top of the support plate is rotatably connected to a driven roller. The device is provided with a cleaning tube, the outer wall of the cleaning tube is fixedly connected to a cleaning brush, the cleaning brush is spirally distributed, the outer wall of the cleaning tube is provided with a plurality of water outlet holes, and the inner wall of the driven roller is in full contact with the cleaning brush, so that the cleaning brush can rub the inner wall of the oil pipe. However, the device has the problem that the oil pipe to be cleaned is put on the cleaning tube. The tube is placed between the driven roller and the active roller, so as to clean the inner wall and the outer wall of the oil pipe. However, the diameter specifications of the oil pipes in real life are various, and the thickness of the cleaning tube responsible for cleaning the inner wall of the oil pipe of the oil pipe cleaning drill is fixed, and the height of the fixed plate for installing the fixed cleaning tube is also fixed. This results in that if the oil pipe is thicker, it is difficult to rely on the cleaning tube of fixed size to clean the inner wall of the oil pipe. If multiple cleaning tubes of different specifications are made to cope with oil pipes of different thicknesses, the use cost will increase. Therefore, an oil pipe cleaning drill is proposed to solve the problem that the existing oil pipe cleaning drill is difficult to quickly clean the inner wall according to the diameter of the oil pipe.

[0024] Furthermore, the screw 13 passes through the adjusting block 12 and is threadedly connected. The intersection of the screw 13 and the swivel seat 6 is rotatably connected by a bearing. The screw 13 is driven by a knob to move the adjusting block 12 in the adjusting groove 11 until the roller brush 8 fits the inner wall of the oil pipe 4. The cleaning roller 3 and the roller brush 8 are driven by an external drive device and a motor 7 to fully clean the oil pipe 4.

[0025] Furthermore, the limiting mechanism 9 includes a fixing frame 901 fixed on the top of the water collecting tank 2, and an electric push rod 902 is fixedly connected to the bottom of the fixing frame 901, and an arc-shaped limiting seat 903 is fixedly connected to the bottom of the electric push rod 902. The arc-shaped bottom surface of the arc-shaped limiting seat 903 is very smooth. When the oil pipe 4 is placed between the cleaning rollers 3, the electric push rod 902 at the bottom of the fixing frame 901 can be opened to drive the arc-shaped limiting seat 903 to move down to slightly squeeze and contact with the oil pipe 4, thereby preliminarily limiting the oil pipe 4. In combination with the very smooth arc-shaped limiting seat 903, it is ensured that the oil pipe 4 can be smoothly rotated and cleaned by the cleaning roller 3, thereby improving the cleaning effect of this oil pipe cleaning drill tool.

[0026] Furthermore, the limiting water injection mechanism 10 includes a fixed seat 101 fixed on one side of the water collecting tank 2, the top of the fixed seat 101 is slidably connected to a limiting plate 102, the top of the fixed seat 101 is penetrated by a bolt 103 and threadedly connected, and the outer ring of one side of the roller brush 8 is fixedly connected to a second limiting plate 108, the limiting plate 102 and the second limiting plate 108 are very smooth on the side facing the oil pipe 4, and the top of the fixed seat 101 is lower than the bottom of the roller brush 8.

While water is injected into the oil pipe 4, part of the water is injected into the drain pipe 105 fixed by the support plate 107 through the connecting hose 106, and then sprayed toward the cleaning roller 3 from the drain hole, and the cleaning of the oil pipe 4 can be started, thereby achieving the purpose of limited water injection and comprehensive cleaning of the oil pipe 4.

[0028] Working principle: When using this oil pipe to clean the drill bit, put the oil pipe on the roller brush 8 and place it between the two cleaning rollers 3. Use the limiting mechanism 9 and the limiting water injection mechanism 10 to limit the oil pipe 4 from the top and both sides. While spraying water to the oil pipe 4 and the cleaning roller 3, use the knob to drive the screw 13 to drive the adjustment block 12 in the adjustment groove 11 to move until the roller brush 8 fits the inner wall of the oil pipe 4. Then, turn on the external drive device and the motor 7 to drive the cleaning roller 3 and the roller brush 8 to rotate, and clean the outer wall and inner wall of the oil pipe 4 respectively, which solves the problem that the existing oil pipe cleaning drill bit is difficult to quickly clean the inner wall according to the diameter of the oil pipe; the water generated by cleaning will directly flow into the water collecting tank 2, which is convenient for the subsequent treatment of the cleaning water and avoids the waste of water resources.
