[0002] In oil development and other engineering construction projects, oil pipelines are a type of material used in large quantities and are important components for transporting oil. However, oil pipelines are very likely to collide during handling or transportation, which can damage the threads. Grease, dust, and impurities are also easily introduced into the pipe body. In order to avoid damage to the pipe threads and contamination of the interior of the pipe, protective caps are usually used to seal the pipe thread positions at both ends of the oil pipe. After arriving at the project site, the protective caps need to be removed using an F-type wrench.
[0003] In the process of removing the protective cap, the protective cap and the pipe thread are often blocked very tightly, making it difficult to remove, especially when the pipe diameter is large, it is more difficult to remove, time-consuming and labor-intensive, and the protective cap is often damaged during the removal process, resulting in the protective cap being scrapped. To this end, we propose a tool for removing the oil pipeline thread protective cap. Utility Model Content

DETAILED DESCRIPTION
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0020] like Figure 1-6 As shown, a tool for removing a threaded protective cap of a petroleum pipeline in this embodiment includes a hexagonal turntable, a hexagonal screw hole is provided in the center of the turntable, and a screw hole flange is provided on the periphery of the hexagonal screw hole. A torque handle is provided on the outside of the turntable, a fixed flange is provided on the top of the torque handle, a hexagonal screw is provided in the center of the fixed flange, the hexagonal screw matches the hexagonal screw hole, the hexagonal screw is screwed into the hexagonal screw hole, and the fixed flange is fitted with the screw hole flange and fixedly connected by bolts, so that the turntable is fixedly connected to the torque handle, and when the torque handle is turned, the turntable is driven to rotate. Three adjustable gripper units are evenly distributed circumferentially on the outer periphery of the turntable, and the angle between two adjacent adjustable gripper units is 120°. The three adjustable gripper units grip the inner wall or the outer periphery of the protective cap, and the torque handle is turned to drive the turntable to rotate, so that the adjustable gripper unit and the protective cap rotate synchronously, and then the protective cap is screwed out from the pipe mouth.
[0021] The adjustable gripper unit includes a front gripper, a middle gripper and a rear gripper respectively; a front gripper plug is provided on one side of the front gripper, and the left and right sides of the front gripper are arc-shaped surfaces protruding outward, and the curvature of the arc-shaped surfaces is 0.5-1°, which increases the contact surface between the front gripper and the protective cap. A middle groove is provided on one side of the middle gripper, the middle groove matches the front gripper, and a middle gripper plug is provided on the other side; a rear groove is provided on one side of the rear gripper, the rear groove matches the middle gripper, and a rear gripper plug is provided on the other side of the rear gripper. The outer edge of the turntable is provided with turntable grooves, and connecting rods are respectively set on the top of the turntable groove, the middle groove and the rear groove. A plurality of circumferentially evenly distributed through grooves are respectively provided on the outer circumference of the connecting rod, and a socket is respectively provided in any through groove. The rear gripper plug-in block is inserted into the socket of the connecting rod in the turntable groove, the middle gripper plug-in block is inserted into the socket of the connecting rod in the rear gripper groove, and the front gripper plug-in block is inserted into the socket of the connecting rod in the middle gripper groove, so as to realize the connection between the front gripper, the middle gripper, the rear gripper and the turntable. According to the aperture size of the protective cap, the front gripper plug-in block, the middle gripper plug-in block and the rear gripper plug-in block are selected to be inserted at the corresponding socket position, and then the angle of the gripper unit is adjusted to grab protective caps of different pipe diameters to adapt to protective caps of different pipe diameters. After unscrewing the protective cap, the front gripper plug block selects the socket on the connecting rod in the middle gripper groove, so that the front gripper is stored in the middle gripper, and the middle gripper plug block selects the socket on the connecting rod in the rear gripper groove, so that the middle gripper is stored in the rear gripper, which reduces the volume of the disassembly tool and is easy to carry.
[0022] The front gripper's front, rear, left and right sides, the middle gripper's left and right sides, and the rear gripper's left and right sides are respectively provided with friction lines to form a friction layer, thereby increasing the friction when the gripper unit grabs the protective cap.
[0023] The torque handle of the present application uses the principle of leverage to easily and labor-savingly rotate the rotating disk and the gripper unit, thereby removing the protective cap from the pipe mouth, thus improving work efficiency. The gripper unit grips the outer periphery or inner wall of the protective cap, and will not touch the relevant part at all during use, thus avoiding damage to the threads of the oil pipe and reducing the scrap rate of the oil pipe. The front gripper plug-in block, the middle gripper plug-in block, and the rear gripper plug-in block are inserted at corresponding socket positions, and then the angle of the gripper unit is adjusted to grab the protective cap to adapt to protective caps of different pipe diameters, or the front gripper can be stored in the middle gripper, and the middle gripper can be stored in the rear gripper, thus reducing the size of the disassembly tool and making it easier to carry.
