Abstract
Description
Technical Field
[0001] This utility model relates to the field of tubing power pliers technology, and more specifically, to a tubing power pliers notching device. Background Technology
[0002] Tubing power pliers are common tools used in the oil and gas industry, especially in drilling and well workover operations. Their main function is to clamp tubing for rotation, movement, fixing, and disassembly. Tubing power pliers are widely used in oil well construction, well workover operations, equipment installation, and maintenance, particularly in environments requiring high torque. They typically utilize a hydraulic system to generate powerful clamping and rotational forces to clamp, rotate, or disassemble the tubing. The hydraulic system, controlled by pressurized oil, drives the jaws to generate efficient clamping force on the pipe. Simultaneously, the transmission system on the pliers converts hydraulic power into rotational power, thereby achieving the rotation or fixing of the pipe.
[0003] However, existing tubing power pliers still have some problems in actual use. For example, when clamping tubing, the notch of the swivel clamp needs to be aligned with the tubing, and then the swivel clamp of the tubing power pliers is placed outside the tubing. During this process, the notch lacks protective measures, which can easily cause the swivel clamp to collide directly with the tubing, resulting in the tubing bending and affecting subsequent use. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a tubing power clamp notch device that overcomes or at least partially solves the above technical problems.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a tubing power wrench notch-setting device, including a rotating wrench with a tubing notch inside. A fixing box is provided on the top surface of the rotating wrench, and a mounting groove is provided inside the fixing box. A protective mechanism is provided inside the mounting groove, and a laser light is fixedly installed inside the mounting groove. The protective mechanism includes a mounting frame, which is fixedly installed inside the mounting groove. A rectangular groove is provided inside the mounting frame, and the size of the rectangular groove corresponds to the size of the tubing notch.
[0007] In a preferred embodiment, both sides of the rectangular groove are provided with snap-fit grooves, and snap-fit plates are movably snapped into the interior of the snap-fit grooves. A plug-in shaft is fixedly installed on one side surface of the snap-fit plate, and one end of the plug-in shaft extends to the outside of the mounting bracket.
[0008] In a preferred embodiment, a circular can is provided on one side of the mounting bracket. The circular can is fixedly installed inside the mounting groove. A connecting pipe is sealed and snapped into the inside of the circular can. One end of the insertion shaft is fixedly connected to one side surface of the connecting pipe.
[0009] In a preferred embodiment, a spring is provided inside the cylindrical can, one end of which is fixedly connected to the inner wall of one side of the cylindrical can, and the other end of which is fixedly connected to the surface of one side of the connecting pipe.
[0010] In a preferred embodiment, both the plug shaft and the snap-fit plate are hollow structures. A one-way valve is fixedly installed on the outer surface of the plug shaft, and a connecting pipe is fixedly connected to the outer surface of the cylindrical tank. A one-way valve is fixedly installed on the outer surface of the connecting pipe.
[0011] In a preferred embodiment, the interior of the fixed box is a hollow structure, the interior of the fixed box is filled with a surfactant, one end of the connecting pipe extends into the interior of the fixed box, and a one-way valve is fixedly installed on its outer surface.
[0012] In a preferred embodiment, a fixing bracket is fixedly installed on both sides of the snap-fit plate, and a liquid outlet hole is opened on one side of each fixing bracket.
[0013] In a preferred embodiment, a fixing plate is fixedly installed on the bottom surface of the fixing box, and the fixing box is detachably installed on the top surface of the rotating clamp via the fixing plate.
[0014] The present invention provides a tubing power wrench notch fitting device, the advantages of which include:
[0015] 1. By setting a snap-fit plate, as the oil pipe enters, the snap-fit plate can be pushed to move towards the inside of the mounting groove. During the movement, the plug shaft can simultaneously drive the connecting pipe towards the inside of the round tank, causing the spring to deform. This reduces the impact force of the oil pipe entering the oil pipe notch. Furthermore, after the oil pipe enters the oil pipe notch, it first contacts the snap-fit plate, thus avoiding direct contact with the inner wall of the oil pipe notch and protecting the oil pipe.
[0016] 2. By setting a fixed frame, when the connecting pipe moves into the round tank under the drive of the plug shaft, the surfactant inside the round tank can be squeezed into the plug shaft and then into the snap plate. Finally, it enters the fixed frame and is sprayed out onto the surface of the oil pipe through the liquid outlet hole on the surface of the fixed frame. This decomposes the oil stains on the outer surface of the oil pipe clamping part, so that the oil pipe can be clamped more stably when it enters the clamping part inside the oil pipe notch.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Reference Figures 1-4This utility model provides a technical solution: a tubing power pliers notch-setting device, including a rotating pliers 1, with a tubing notch 2 inside the rotating pliers 1, a fixing box 3 on the top surface of the rotating pliers 1, an installation groove 5 inside the fixing box 3, a protective mechanism 6 inside the installation groove 5, and a laser light 7 fixedly installed inside the installation groove 5. The protective mechanism 6 includes a mounting bracket 601, which is fixedly installed inside the installation groove 5. A rectangular groove 602 is opened inside the mounting bracket 601, and the opening size of the rectangular groove 602 corresponds to the opening size of the tubing notch 2.
[0025] During operation, when aligning the notch, simply turn on the laser lamp 7. When the laser lamp 7 is turned on, it emits a straight beam of light. When the rotating clamp 1 is aligning the notch, the light is focused on the middle of the outer surface of the oil pipe, which allows the oil pipe notch 2 to be aligned with the oil pipe, thus achieving the purpose of facilitating the quick alignment of the oil pipe notch 2 with the oil pipe.
[0026] A fixing plate 4 is fixedly installed on the bottom surface of the fixing box 3. The fixing box 3 can be detachably installed on the top surface of the rotating clamp 1 through the fixing plate 4. The fixing plate 4 enables the quick installation of the mounting slot 5, increasing the convenience of the overall assembly of the device.
[0027] Both sides of the rectangular groove 602 are provided with snap-fit grooves 603. A snap-fit plate 604 is movably snapped into the inside of the snap-fit groove 603. A plug shaft 605 is fixedly installed on one side surface of the snap-fit plate 604. One end of the plug shaft 605 extends to the outside of the mounting bracket 601. A round can 606 is provided on one side of the mounting bracket 601. The round can 606 is fixedly installed inside the mounting groove 5. A connecting pipe 607 is sealed and snapped into the inside of the round can 606. One end of the plug shaft 605 is fixedly connected to one side surface of the connecting pipe 607. A spring 610 is provided inside the round can 606. One end of the spring 610 is fixedly connected to one side inner wall of the round can 606. The other end of the spring 610 is fixedly connected to one side surface of the connecting pipe 607.
[0028] During operation, once the oil pipe notch 2 is aligned with the oil pipe, the rotating clamp 1 can be moved to gradually insert the oil pipe into the oil pipe notch 2. As the oil pipe enters, it first contacts the clamping plate 604. With the entry of the oil pipe, the clamping plate 604 is pushed to move inside the clamping groove 603 towards the inner side of the mounting groove 5. During the movement, the insertion shaft 605 drives the connecting pipe 607 to move towards the inside of the round tank 606, causing the spring 610 to deform. This reduces the impact force of the oil pipe entering the oil pipe notch 2. Furthermore, after entering the oil pipe notch 2, the oil pipe first contacts the clamping plate 604, thus avoiding direct contact with the inner wall of the oil pipe notch 2, protecting the oil pipe and allowing it to enter the oil pipe notch 2 gradually rather than with a rapid impact.
[0029] Both the plug shaft 605 and the snap-fit plate 604 are hollow structures. A one-way valve 608 is fixedly installed on the outer surface of the plug shaft 605. A connecting pipe 607 is fixedly connected to the outer surface of the round tank 606. A one-way valve 608 is fixedly installed on the outer surface of the connecting pipe 607. The interior of the fixed box 3 is hollow and filled with surfactant. One end of the connecting pipe 607 extends into the interior of the fixed box 3 and a second one-way valve 609 is fixedly installed on its outer surface. Fixing brackets 612 are fixedly installed on both sides of the snap-fit plate 604. A liquid outlet hole 611 is opened on one side of the fixing bracket 612.
[0030] During operation, when the connecting pipe 607 moves into the round tank 606 under the drive of the plug shaft 605, it can squeeze the surfactant inside the round tank 606 into the plug shaft 605 and into the snap plate 604, and finally into the fixing frame 612. Then, it is sprayed out onto the surface of the oil pipe through the liquid outlet hole 611 on the surface of the fixing frame 612, decomposing the oil stains on the outer surface of the oil pipe clamping part. This allows the oil pipe to be clamped more stably when it enters the clamping part inside the oil pipe notch 2. When the oil pipe is removed from the inside of the oil pipe notch 2, the spring 610 returns to its original state and re-draws the surfactant inside the fixing plate 4 into the round tank 606.
[0031] Specifically, the working process or principle of this tubing power pliers notching device is as follows: When in use, the laser lamp 7 is turned on, emitting a straight beam of light. As the rotating pliers 1 notches the tubing, the light focuses on the center of the outer surface of the tubing, aligning the tubing notch 2 with the tubing. As the tubing enters, the clamping plate 604 moves inside the clamping groove 603 towards the inner side of the mounting groove 5. During this movement, the insertion shaft 605 simultaneously drives the connecting pipe 607 towards the interior of the cylindrical container 606, causing the spring 610 to deform, thereby guiding the tubing into the container. The impact force inside the oil pipe notch 2 is mitigated. After entering the oil pipe notch 2, the oil pipe first contacts the snap plate 604, thus avoiding direct contact with the inner wall of the oil pipe notch 2 and protecting the oil pipe. When the connecting pipe 607 moves into the round tank 606 under the drive of the plug shaft 605, it can squeeze the surfactant inside the round tank 606 into the plug shaft 605 and into the snap plate 604, and finally into the fixing frame 612. Then, it is sprayed onto the surface of the oil pipe through the liquid outlet hole 611 opened on the surface of the fixing frame 612, decomposing the oil stains on the outer surface of the oil pipe clamping part.
[0032] It should be noted that the laser lamp 7 is a device or equipment that exists in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
