Abstract
Description
Technical Field
[0001] This application relates to the field of petroleum exploration technology, and more specifically, to a flange steel ring loading and unloading tool. Background Technology
[0002] During oil and gas well development and drilling / workout operations, it is necessary to disassemble and reassemble production pipelines, GC manifolds, venting lines, and other pipelines connected by flanges. This necessitates the installation or removal of steel rings between the flanges. Due to the lack of specialized tools, installing or removing these steel rings is difficult and poses certain safety risks.
[0003] The steel ring is a key sealing element in flange connections. When the flange bolts are tightened, the steel ring is compressed into the groove between the two flange faces, filling the tiny gap between them and forming a sealed barrier to prevent media leakage from the connection. The steel ring is typically made of steel, possessing high strength and toughness. It is generally annular, and its cross-sectional shape can vary, commonly including flat and circular shapes. The sealing principle of the steel ring mainly relies on its elastic deformation. Because it is made very smooth, during on-site construction, due to space constraints, workers often use ropes, handheld methods, or tools to place the steel ring between the two connecting flanges, then squeeze the flanges and steel ring together. This installation method suffers from low precision, hand injuries from pressure, and difficulty in positioning the steel ring. It is not only inefficient but also easily damages the steel ring itself, causing seal failure and increasing the risk of media leakage. Utility Model Content

[0036] Please refer to Figure 1 and Figure 2This application provides a flange steel ring loading and unloading tool, mainly comprising a gripping body 1 and an operating component 2. The gripping body 1 is provided with a contact portion 11, at least a portion of which is in contact with the side peripheral wall of the flange steel ring. At least one magnetic suction component 12 is embedded inside the contact portion 11, and the magnetic suction component 12 is located on the side of the contact portion 11 facing the flange steel ring to be loaded. At least a portion of the magnetic suction component 12 is embedded in the contact portion 11 and can be magnetically connected to the side peripheral wall of the flange steel ring to realize the gripping function of the flange steel ring. The operating component 2 is located on the side of the gripping body 1 away from the contact portion 11. Its first end is fixedly connected to the gripping body 1, and its second end is for hand gripping, so as to facilitate the operator to operate the flange steel ring loading and unloading tool to perform flange steel ring loading and unloading operations.
[0037] The gripping body 1 can be block-shaped, plate-shaped, or shell-shaped. It can directly fit against the side wall of the flange steel ring. For example, it can adopt an arc-shaped structure or have an arc-shaped inner cavity. It can also fit against the side wall of the flange steel ring through the magnetic suction part 12 to improve the loading and unloading accuracy of the flange steel ring.
[0038] The operating component 2 can be rod-shaped, strip-shaped, plate-shaped, block-shaped, etc. It can be an integral structure or a split structure. For example, the various parts of the operating component 2 can be connected by threads, snaps, fasteners, bolts, or rotational connections. The first end of the operating component 2 can be integrally connected to the gripping body 1, or it can be separately connected by threads, snaps, fasteners, locking devices, etc.
[0039] In this embodiment, a magnetic suction member 12 is provided inside the fitting part 11 of the gripping body 1. The magnetic suction member 12 can be completely embedded inside the fitting part 11 or partially protruding from the fitting part 11. The magnetic suction member 12 is attracted to the side peripheral wall of the flange steel ring, so as to realize the gripping head gripping the flange steel ring. The magnetic suction member 12 can be made of strong magnetic material to ensure magnetic attraction strength.
[0040] When installing the steel ring, first determine the flange size and identify the steel ring model. Select the matching gripper head and connect it to the operating handle 23. Use the gripper head to grip the middle plane of the outer wall of the steel ring, while holding the other end of the operating handle 23. Feed the steel ring into the steel ring groove of one flange, then install the other flange in place. After installation, pull out the operating handle 23, separating the steel ring from the gripper head, completing the installation of the flange steel ring.
[0041] When removing the steel ring, after removing the flange bolts, insert the flange steel ring removal tool into the flange gap, attach it to the exposed side wall of the steel ring, slightly separate the two flanges, and then lift out the flange steel ring to complete the removal of the flange steel ring.
[0042] When replacing a flange ring, to quickly remove it, loosen all flange bolts, leaving enough space between the two flanges for the flange ring to be removed. Remove some bolts to allow the flange ring removal tool to access the ring. Then, repeat the removal and installation steps, and finally tighten all flange bolts to quickly replace the flange ring.
[0043] In one specific embodiment, the fitting portion 11 is provided with an arc-shaped fitting surface 111, which is located on the side of the fitting portion 11 facing the flange steel ring to be installed. The magnetic suction member 12 is embedded inside the fitting portion 11, and the magnetic suction surface of the magnetic suction member 12 coincides with the fitting surface 111. The curvature of the arc-shaped fitting surface 111 is the same as the outer diameter of the flange steel ring. When installing or removing the flange steel ring, under the magnetic attraction of the magnetic suction member 12, the arc-shaped fitting surface 111 of the gripping body 1 completely adheres to the flange steel ring to be removed, so as to ensure the firmness of the magnetic connection. In this embodiment, the gripping body 1 can be set according to steel rings of different sizes to adapt to commonly used flange steel rings.
[0044] Optionally, the central angle of the mating surface 111 ranges from 90 degrees to 180 degrees, which can better fit the profile of the side wall of the flange steel ring, increase the area of the mating surface 111, improve the gripping stability and reliability, and reduce the risk of displacement or slippage during the gripping process.
[0045] In another specific embodiment, the fitting portion 11 further includes multiple fitting sub-parts and a locking assembly. All the fitting sub-parts are circumferentially distributed, and the locking assembly includes multiple locking elements, such as bolts and screws. Adjacent fitting sub-parts are connected using the locking assembly. At least one magnetic suction element 12 is embedded inside each fitting sub-part. This facilitates adjustment and assembly according to flange steel rings of different sizes. The fitting sub-parts are fixed by the locking assembly, and the curvature formed by each fitting sub-part can be adjusted to achieve gripping of different types of flange steel rings, increasing the versatility and flexibility of the loading and unloading tool.
[0046] Regarding the specific structure of the magnetic suction component 12, in a first embodiment, the magnetic suction component 12 includes a connecting part and a magnetic suction part, with the magnetic suction part fixedly connected to the side of the connecting part opposite to the fitting part 11. The connection between the connecting part and the fitting part 11 can be varied; for example, the connecting part can be provided with an external thread, and the fitting part 11 can be provided with an internal thread, with the two connected by threads to adjust the adsorption position.
[0047] In a second embodiment, the fitting part 11 can be provided with a pin, which has multiple first insertion holes. The connecting part has an insertion cavity and multiple second insertion holes. The pin is inserted into the insertion cavity. The corresponding first and second insertion holes can be selected according to the diameter of the flange steel ring, and the pin is inserted into the insertion hole to fix the radial position of the magnetic attractor 12, thereby realizing the adjustment of the radial position of the magnetic attractor 12. In a third embodiment, an adjustment groove can be provided inside the fitting part 11. An adjustment slope is provided in the adjustment groove, and the connecting part has a sliding slope. Both the adjustment slope and the sliding slope can be a plane, a stepped surface, or a curved surface. The connecting part and the adjustment groove slide together. The connecting part moves laterally to change the connection depth in the vertical direction, thereby adjusting the radial position of the magnetic attractor 12.
[0048] The above connection scheme provides multiple options for adjusting the position of the magnetic chuck 12, making it easy to adjust the relative position of the magnetic chuck 12 and the flange steel ring, thereby improving the gripping effect.
[0049] The magnetic components 12 can be evenly distributed circumferentially on the mating surface 111. This uniform circumferential distribution ensures that the gripping force is applied evenly to the side wall of the flange steel ring, preventing excessive localized stress that could lead to deformation or damage to the steel ring. Furthermore, the magnetic components 12 can also be arranged in an array along both the circumferential and axial directions on the mating surface 111. This array arrangement further increases the adsorption area and strength, enhancing gripping stability and ensuring the flange steel ring remains stable during installation and removal.
[0050] Optionally, along the axial direction, the thickness of the fitting portion 11 can be equal to the thickness of the gripping body 1, and the thickness of the fitting portion 11 is less than the thickness of the flange steel ring. This helps the fitting portion 11 avoid the flange end face, ensuring that the fitting surface 111 of the fitting portion 11 completely conforms to the side peripheral wall of the flange steel ring, while preventing the gripping body 1 from protruding excessively and affecting the loading and unloading operation, thus ensuring a good fit between the loading and unloading tool and the flange steel ring and equipment components.
[0051] In one specific embodiment, the operating component 2 includes a connecting rod 21 and a connecting component 22. The connecting component 22 is located at the first end of the connecting rod 21. The gripping body 1 and the connecting component 22 are respectively provided with a first connecting structure 112 and a second connecting structure, and the two are detachably connected.
[0052] The first connecting structure 112 can be a nut that is fixedly installed in the middle of the outer wall of the gripping body 1. The connecting piece 22 can be provided with a threaded structure. The connecting piece 22 is threadedly connected to the nut of the gripping body 1 to facilitate disassembly and assembly, and to facilitate connection of gripping bodies 1 of different sizes, so as to achieve matching with commonly used flange steel ring gripping bodies 1.
[0053] Link 21 can be composed of multiple coaxially distributed link segments, with adjacent link segments connected by sleeves to achieve telescopic function and adapt to loading and unloading needs at different distances.
[0054] For ease of operation, a handle 23 can be installed at the second end of the connecting rod 21. By holding the handle 23, the flange steel ring can be installed or removed, facilitating the replacement or maintenance of the operating component 2. The handle 23 can be equipped with an anti-slip structure to provide a comfortable grip for the operator, prevent slippage, and facilitate the application of force to control the tool's movement.
[0055] This application's flange ring loading and unloading tool utilizes magnetic attraction to remove the flange ring from the side of the flange gap. The attraction is precise and reliable, significantly improving loading and unloading efficiency. Simultaneously, the detachable operating component 2 facilitates quick replacement to accommodate different flange ring models, saving costs.
[0056] The operator uses the telescopic connecting rod 21 to insert the gripping body 1 into the flange. The fitting part 11 fits tightly against the flange steel ring, and the magnetic suction part 12 is attracted to complete the disassembly operation. Even in complex environments with limited space and poor visibility, this flange steel ring loading and unloading tool can still maintain a firm gripping force, achieve precise control, and effectively avoid damage to equipment parts due to improper operation.
[0057] The flange steel ring installation and removal tool provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
