Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting removal, and more specifically, to a device for quickly removing pipeline pipe fittings. Background Art

[0002] In industries such as petroleum, natural gas, chemical engineering, shipbuilding and maintenance, the pipeline system is a key component for transporting media. The installation and removal of pipeline pipe fittings occur frequently, especially during equipment overhaul, maintenance or upgrade. The traditional manual removal method is not only time-consuming and laborious, but also in narrow or high-risk environments, the difficulty and danger of manual operation are greatly increased. To solve this problem, a device for quickly removing pipeline pipe fittings has emerged, aiming to improve the removal efficiency of pipeline pipe fittings while reducing labor intensity and potential safety hazards.

[0003] Currently, the existing method is to use an electric wrench to quickly remove nuts. However, when using this method, another hand is required to hold the bolt with a wrench, so both hands need to exert force, which will be relatively tiring. Moreover, the removed bolt still needs to be manually pulled out, which is rather inconvenient.

[0004] Therefore, it is necessary to propose a device for quickly removing pipeline pipe fittings to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that currently, the existing method is to use an electric wrench to quickly remove nuts. However, when using this method, another hand is required to hold the bolt with a wrench, so both hands need to exert force, which will be relatively tiring. Moreover, the removed bolt still needs to be manually pulled out, which is rather inconvenient.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A device for quickly removing pipeline pipe fittings includes a cylinder. One end of the cylinder is provided with an internal hexagonal groove for inserting the hexagonal end of the bolt. A ring is fixedly connected to the outer peripheral surface of the cylinder. Inserting rods are slidably arranged at equal intervals along the circumferential direction of the cylinder in the ring. The radius of the ring is equal to the minimum distance from the center of the connection hole on the outer periphery of the flange to the outer peripheral surface, so that the inner side surface of the inserting rod can be attached to the outer peripheral surface of the flange. The end of the inserting rod is flush with the end of the cylinder at one end of the internal hexagonal groove.

[0008] A limiting ring is fixedly connected to the inner side surface of the cylinder. A magnetic attraction mechanism for adsorbing the end of the bolt is horizontally slidably connected to the middle of the limiting ring.

[0009] Furthermore, a sliding block is slidably connected in the cylinder on the side of the limiting ring away from the internal hexagonal groove. A transmission rod is fixedly connected to the side of the sliding block away from the limiting ring. The transmission rod penetrates through the end of the cylinder, and a circular plate is fixedly connected to this end.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, A quick disassembly device for pipeline pipe fittings, which is used to disassemble the pipe fitting 1 connected by bolts 3 and nuts 4. It includes the pipe fitting 1 provided with a flange 2. A connection hole for inserting the bolt 3 is opened on the outer circumference of the flange 2. By screwing the nut 4 onto the bolt 3, the flanges 2 on two adjacent pipe fittings 1 are connected. The disassembly device includes a cylinder 5. An internal hexagonal groove 6 for inserting the hexagonal end of the bolt 3 is opened at one end of the cylinder 5. The shape of the hexagonal end of the bolt 3 is the same as that of the internal hexagonal groove 6, ensuring that there is no relative rotation between the bolt 3 and the cylinder 5. A ring 13 is fixedly connected to the outer circumferential surface of the cylinder 5. Insertion holes are equally spaced along the circumferential direction of the cylinder 5 in the ring 13. Insertion rods 14 are slidably arranged in the insertion holes. Every two adjacent insertion rods 14 are in contact with each other. The radius of the ring 13 is equal to the minimum distance from the center of the connection hole to the outer circumferential surface of the flange 2, so that the inner side surface of the insertion rod 14 slid to the outer circumferential surface of the flange 2 can fit the outer circumferential surface of the flange 2, thus realizing the restriction of the rotation of the cylinder 5, which can be more labor-saving. The end of the insertion rod 14 is flush with the end of the cylinder 5 at one end of the internal hexagonal groove 6. The length of the insertion rod 14 can also be less than this distance, as long as it is ensured that the insertion rod 14 can slide to the outer circumferential surface of the flange 2;

[0021] A limiting ring 7 is fixedly connected to the inner side surface of the cylinder 5 to limit the insertion position of the bolt 3. A magnetic attraction mechanism for adsorbing the end of the bolt 3 is horizontally slidably connected to the middle of the limiting ring 7.

[0022] In this embodiment, through the cooperative setting between the cylinder 5 and the insertion rod 14, by pulling out the insertion rod 14 to fit the flange 2, at this time, the step of the worker using a wrench to hold the bolt 3 can be omitted, which is more labor-saving. At the same time, through the setting of the magnetic attraction mechanism, after the nut 4 is removed from the bolt 3, the bolt 3 can be directly pulled out from the connection hole, thus improving the disassembly efficiency.

[0023] Specifically, as shown in combination with Figure 2 and Figure 3 , a sliding block 8 is slidably connected in the cylinder 5 on the side of the limiting ring 7 away from the internal hexagonal groove 6. A transmission rod 9 is fixedly connected to the side of the sliding block 8 away from the limiting ring 7. The transmission rod 9 penetrates through the end of the cylinder 5, and a circular plate 10 is fixedly connected to this end. There is a certain distance between the circular plate 10 and the cylinder 5 in the normal state, which is convenient for the worker's hand to enter and convenient for pulling the circular plate 10.

[0024] Specifically, as shown in combination with Figure 3 , the magnetic attraction mechanism includes a magnet 12 fixedly connected to the end of the sliding block 8 away from the transmission rod 9. The magnet 12 is located inside the limiting ring 7. The size of the magnet 12 can be smaller than the size inside the limiting ring 7, as long as it can ensure the adsorption of the bolt 3.

[0025] Specifically, as shown in combination with Figure 3As shown, a spring 11 is arranged in a cylinder 5 at one end of the sliding block 8 away from the limit ring 7. The spring 11 is sleeved on the outer peripheral surface of the transmission rod 9, and the two ends of the spring 11 are respectively fixedly connected to the sliding block 8 and the inner side surface of the cylinder 5, so as to realize the automatic reset of the magnet 12 and facilitate subsequent disassembly.

[0026] Usage method: First, align the hexagonal socket 6 with the bolt 3, then sleeve the hexagonal socket 6 on the end of the bolt 3. At this time, the magnet 12 will adsorb the end of the bolt 3, and then push the corresponding plug rod 14 so that the inner side of the plug rod 14 can be attached to the outer peripheral surface of the flange 2 to limit the rotation of the cylinder 5. At this time, the nut 4 can be removed by an electric wrench. After the removal is completed, pulling the cylinder 5 can drive the bolt 3 to be pulled out from the connection hole. After being pulled out, by pulling the round plate 10, the round plate 10 drives the sliding block 8 to compress the spring 11, realizing the separation of the magnet 12 and the bolt 3.
