Description

Technical Field

[0001] This utility model relates to the field of oil nozzle wrench technology, and in particular to an oil nozzle disassembly and cleaning tool. Background Technology

[0002] A wellhead is a device used in oil wells to extract oil. It has nozzle sleeves with detachable nozzles attached. The other end of the nozzle is connected to a tubing to deliver the oil from the wellhead to the surface. By changing nozzles with different orifice diameters, the pressure and flow rate of the oil as it flows through the surface can be controlled.

[0003] The existing nozzles are cylindrical nozzles with an oil passage inside. Oil flows from the nozzle sleeve on the wellhead into the oil passage of the nozzle, and then flows from the oil passage into the oil pipeline.

[0004] Because the oil in the wellhead is under pressure, when the oil enters the nozzle's passageway, it has an erosive effect on the nozzle's inlet. This erosion is even more pronounced when the crude oil in the well has a high sediment content. Since the existing nozzle inlet forms a right angle with the nozzle's inlet side end face, the nozzle inlet experiences a significant impact force from the oil, making it prone to developing erosion grooves.

[0005] To ensure safe production of oil wells, the nozzles need to be removed from the tree periodically for cleaning or replacement. Utility Model Content

[0006] This utility model provides a tool for disassembling and cleaning oil nozzles, used for disassembling, assembling and cleaning oil nozzles.

[0009] Hold the handle and install it in a cross configuration with the connecting rod via a coupling;

[0010] A cleaning hook is provided on the grip handle, the tip of which is bent to form a hook tip for hooking up contaminants on the nozzle.

[0011] In one embodiment, the grip handle is rod-shaped, and an axial cavity extending along its own axis is formed at one axial end of the grip handle, and the cleaning hook is housed in the axial cavity;

[0012] A cover is also provided on one end of the grip handle opposite to the receiving cavity, and the cover is used to close the opening of the receiving cavity.

[0013] In one embodiment, the end of the cleaning hook opposite to the hook tip is inserted into the inner wall of the cover.

[0014] In one embodiment, a insertion groove is formed on the side of the cover facing the receiving cavity;

[0015] The insertion slot is interference-fitted with the end of the cleaning hook that is away from the hook tip, so as to ensure the insertion of the cleaning hook and the cap.

[0016] In one embodiment, the cavity also contains a cleaning brush for brushing the surface of the nozzle.

[0017] In one embodiment, the first magnetic element is a permanent magnet;

[0018] The permanent magnet is sheet-shaped and is fixedly attached to the side wall of the sleeve near the connecting rod.

[0019] In one embodiment, the coupling includes a body, and a first bolt and a second bolt mounted on the body;

[0020] The main body is provided with a first shaft hole and a second shaft hole that are spatially perpendicular to each other and not connected to each other, wherein the first shaft hole and the second shaft hole are used to pass through the connecting rod and the grip handle in a one-to-one correspondence;

[0021] The main body is also provided with a first opening communicating with the first shaft hole and a second opening communicating with the second shaft hole; the first bolt is used to adjust the size of the first opening so that the diameter of the first shaft hole is reduced and the inner wall is tightly attached to the outer wall of the connecting rod, thereby fastening the connecting rod.

[0022] The second bolt is used to adjust the size of the second opening, so that the diameter of the second shaft hole is reduced and the inner wall is tightly fitted to the outer wall of the grip handle, thereby securing the grip handle.

[0023] In one embodiment, the connecting rod is a hollow rod, and stress holes are provided on it;

[0024] The stress hole is configured such that when the torque exerted by the sleeve on the nozzle is greater than a preset value, the cross section where the stress hole is located on the connecting rod will undergo torsional deformation.

[0025] In one embodiment, a second magnetic element is provided on the end of the grip handle away from the cleaning hook;

[0026] The magnetic force of the second magnetic component is adjustable.

[0027] In one embodiment, sleeves are provided at both ends of the connecting rod, and each sleeve has an inner hole that matches the hexagonal nut.

[0028] The inner cross-section of each sleeve is a regular hexagon, and the circumscribed circle diameter of the regular hexagon is different.

[0029] Compared with the prior art, the advantages of this utility model are:

[0030] 1. In this embodiment, the tip of the cleaning hook is bent to form a hook point, which is used to hook out contaminants on the nozzle. The cleaning hook can be used as a dedicated cleaning tool for clogging nozzles. After the nozzle is removed from the nozzle sleeve, the hook point can effectively hook out contaminants such as dirty oil and sand from the nozzle, preventing clogging. In addition, the cleaning hook is located on the handle, which solves the problem of the cleaning hook being easily lost.

[0031] 2. In order to prevent the oil nozzle from falling off the sleeve during the disassembly process using a wrench, the sleeve of the wrench in this embodiment of the present invention is also provided with a first magnetic component. The first magnetic component can magnetically attract the metal disassembly part on the oil nozzle, thereby preventing the oil nozzle from detaching from the sleeve during the disassembly and assembly process.

[0032] 3. In this embodiment, the connecting rod is a hollow rod with stress holes. When the preload of the nozzle reaches the preset value, if the handle is continued to be turned, the part of the connecting rod near the stress holes will undergo torsional deformation to prevent the sleeve from continuing to rotate and to prevent the nozzle from being damaged due to excessive force, thus protecting the nozzle.

[0033] 4. The wrench and handle are detachably mounted on the same coupling, allowing the wrench to be removed from the coupling to replace different models, thus increasing the adaptability of the oil nozzle cleaning tool. Furthermore, the fixed installation of the wrench and handle via the coupling improves the stability of the connection and increases the structural strength of the oil nozzle cleaning tool.

[0043] The present invention will be further described below with reference to the accompanying drawings.

[0044] The oil nozzle in the prior art usually includes an oil nozzle body, which has an oil passage. A connecting part is formed at one end of the oil nozzle body near the oil inlet. The connecting part is connected to the oil nozzle sleeve by a thread or an interference fit.

[0045] A disassembly section is formed at one end of the nozzle body near the oil outlet. The disassembly section has a regular hexagonal cross-section perpendicular to the axis of the oil passage. By applying a hexagonal socket wrench that matches the disassembly section to the disassembly section and rotating the wrench, the nozzle can be removed from the nozzle sleeve. The nozzle can then be cleaned or replaced. Finally, the cleaned or replaced nozzle can be reinstalled using the wrench.

[0046] Because there is a lack of dedicated oil nozzle cleaning tools in the current technology, there may be problems with inadequate cleaning of oil nozzles; in addition, wrenches and cleaning tools are relatively independent and scattered, and are easy to lose.

[0047] To address the aforementioned problems, this utility model provides a tool for disassembling and cleaning oil nozzles, which includes a wrench 1, a handle 2, and a cleaning hook 4.

[0048] The wrench 1 includes a connecting rod 11 and two sleeves 12 of different models located at the two ends of the connecting rod 11. The sleeves 12 are coaxially arranged with the connecting rod 11. The shape and size of the inner hole of the sleeve 12 are adapted to the outer wall of the disassembly part on the grease fitting. Different models of sleeves 12 can be used for grease fittings of different sizes. Specifically, each sleeve 12 has an inner hole that matches a hexagonal nut. The cross-section of the inner hole of each sleeve is a regular hexagon, and the circumscribed circle diameter of the regular hexagon is different. Optionally, the circumscribed circle diameter of the regular hexagonal inner hole of one sleeve is 36 mm and the outer diameter is 46 mm; the circumscribed circle diameter of the regular hexagonal inner hole of the other sleeve is 56 mm and the outer diameter is 66 mm.

[0049] The handle 2 and the wrench 1 are fixedly connected to each other in a cross manner; an anti-slip structure 21 is provided on the handle 2 near the two shaft ends. The outer surface of the anti-slip structure 21 is toothed to increase friction; the anti-slip structure 21 is made of rubber to increase grip comfort.

[0050] In the process of disassembling the nozzle, first, the sleeve 12 is fitted onto the disassembly part of the nozzle. Then, the handle 2 is held with both hands and rotated around the central axis of the connecting rod 11 to rotate the sleeve 12 and the disassembly part on the nozzle, thereby removing the nozzle from the nozzle sleeve.

[0051] In this embodiment, a cleaning hook 4 is also provided on the handle 2. The tip of the cleaning hook 4 is bent to form a hook tip 41, which is used to hook off contaminants on the nozzle. The cleaning hook 4 can be used as a dedicated cleaning tool for clogging nozzles. After the nozzle is removed from the nozzle sleeve, the hook tip 41 can effectively hook off contaminants such as dirty oil and sand from the nozzle, preventing clogging. In addition, the cleaning hook 4 is provided on the handle 2, which solves the problem of the cleaning hook 4 being easily lost.

[0052] Regarding the installation and connection method of the cleaning hook 4 on the grip handle 2, the present invention provides the following two implementation methods.

[0053] In the first embodiment, a fixing seat is welded to the end of the cleaning hook 4 away from the hook tip 41. The fixing seat is hollow and cylindrical, and the inner wall is provided with internal threads. The grip handle 2 is rod-shaped, and the end of the grip handle 2 near where the cleaning hook 4 is located is provided with external threads. The internal threads on the fixing seat are threadedly connected to the external threads on the grip handle 2, thereby detachably installing the cleaning hook 4 on the grip handle 2.

[0054] Of course, an external thread can also be provided on the outer wall of the fixed seat, and a threaded hole can be provided on the shaft end of the grip handle 2. The external thread on the fixed seat is threadedly connected to the threaded hole on the grip handle 2.

[0055] When it is necessary to clean the clogged grease nipple, the cleaning hook 4 can be unscrewed from the handle 2, and then the grease nipple can be cleaned by holding the fixed base with the cleaning hook 4. The cleaning is convenient. After cleaning, the cleaning hook 4 can be installed back onto the handle 2 to prevent the cleaning hook 4 from being lost.

[0056] The second embodiment: the handle 2 is rod-shaped, and a receiving cavity 22 extending along its own axis is formed at one axial end of the handle 2. The cleaning hook 4 is housed in the receiving cavity 22. A cover 23 is also provided on one axial end of the handle 2 opposite to the receiving cavity 22. The cover 23 is used to close the opening of the receiving cavity 22.

[0057] With this setup, when it is necessary to clean the nozzle with the cleaning hook 4, simply open the cover 23 and take out the cleaning hook 4 from the receiving cavity 22; after cleaning the nozzle, insert the cleaning hook 4 into the receiving cavity 22 and close the cover 23 to preserve the cleaning hook 4 and prevent it from being lost.

[0058] The end of the cleaning hook 4 facing away from the hook tip 41 is inserted into the inner wall of the cover 23. Specifically, an insertion groove is formed on the side of the cover 23 facing the receiving cavity 22; the insertion groove is interference-fitted with the end of the cleaning hook 4 facing away from the hook tip 41 to facilitate the insertion of the cleaning hook 4 into the cover 23.

[0059] With this setup, when it is necessary to clean the nozzle using the cleaning hook 4, the cover 23 can be opened and the cleaning hook 4 can be pulled off the cover 23 to facilitate cleaning of the nozzle. After cleaning the nozzle, the cleaning hook 4 is inserted into the inner wall of the cover 23, and then the tip of the cleaning hook 4 is inserted into the receiving cavity 22 and the cover 23 is closed. Since the cleaning hook 4 is inserted and limited on the cover 23, it can prevent the cleaning hook 4 from shaking in the receiving cavity 22, thereby preventing the hook tip 41 from being damaged due to shaking.

[0060] The cavity 22 also houses a cleaning brush for brushing the surface of the nozzle. The cavity 22 may also house tweezers for inserting into the nozzle shaft hole and removing contaminants. The cleaning brush and tweezers can be removed after the cover 23 is opened.

[0061] In order to prevent the oil nozzle from falling off the sleeve 12 during the disassembly of the oil nozzle using the wrench 1, the sleeve 12 of the wrench 1 in this embodiment of the present invention is also provided with a first magnetic element 13. The first magnetic element 13 can magnetically attract the metal disassembly part on the oil nozzle, thereby preventing the oil nozzle from detaching from the sleeve 12 during the disassembly and assembly process.

[0062] Specifically, the first magnetic component 13 is configured as a permanent magnet, which is sheet-shaped and fixedly attached to the side wall of the sleeve 12 near the connecting rod 11.

[0063] When installing the nozzle onto the nozzle sleeve using wrench 1, excessive preload on the nozzle can damage it. To avoid this problem, the connecting rod 11 in this embodiment is hollow and has stress holes 14. The stress holes 14 are configured such that when the torque applied to the nozzle by the sleeve 12 exceeds a preset value, the cross-section of the connecting rod 11 containing the stress holes 14 will undergo torsional deformation. When the preload of the nozzle reaches the preset value, if the handle 2 is continued to be tightened, the portion of the connecting rod 11 near the stress holes 14 will undergo torsional deformation to prevent the sleeve 12 from continuing to rotate and to prevent the nozzle from being damaged due to excessive force, thus protecting the nozzle.

[0064] In this embodiment, a second magnetic element 24 is provided on the end of the handle 2 away from the cleaning hook 4; the magnetic force of the second magnetic element 24 is adjustable. When the connecting part on the nozzle is interference-fitted onto the nozzle sleeve, the second magnetic element 24 can be used to magnetically attract the metal disassembly part on the nozzle, and the magnetic force of the second magnetic element 24 can be gradually increased until the nozzle is pulled off the nozzle sleeve. This improves the applicability of the nozzle disassembly and cleaning tool in this embodiment.

[0065] To improve the connection stability between the connecting rod 11 and the grip handle 2, the two are connected by a coupling 3. Compared to welding, the coupling 3 does not damage the surface structure of the connecting rod 11 and the grip handle 2, and the connection is more stable. In addition, it can be disassembled to replace different models of wrenches 1, increasing the compatibility of cleaning tools for oil nozzles.

[0066] The coupling 3 has the following structure: The coupling 3 includes a block-shaped main body, on which a first shaft hole 31 extending laterally and a second shaft hole 34 extending longitudinally are provided. The two shaft holes are not connected to each other. The first shaft hole 31 is used to pass through the connecting rod 11, and the inner wall of the first shaft hole 31 is adapted to the connecting rod 11; the second shaft hole 34 is adapted to the middle part of the grip handle 2 and is used to pass through the grip handle 2.

[0067] To securely connect the wrench 1 and the coupling 3, the main body in this embodiment is provided with a first opening 32 and a first mounting hole. The first opening 32 communicates with the first shaft hole 31, and the first mounting hole extends along the thickness direction of the first opening 32 and is used to pass a bolt. During installation, the connecting rod 11 is first inserted into the first shaft hole 31, and then the first bolt 33 is passed through the first mounting hole and connected to the nut. The nut is then tightened to secure the connection and reduce the size of the first opening 32, thereby reducing the diameter of the first shaft hole 31 and tightly fitting the inner wall against the outer wall of the connecting rod 11, thus achieving a fixed installation between the wrench 1 and the coupling 3.

[0068] Similarly, in order to securely connect the grip handle 2 and the coupling 3, the main body is also provided with a second opening 35 communicating with the second shaft hole 34, and a second bolt 36 extending along the thickness direction of the second opening 35. During installation, the rod-shaped grip handle 2 is first inserted into the second shaft hole 34, and then the second bolt 36 is passed through the second mounting hole and connected with the nut. The nut is then tightened to secure the grip handle 2 and reduce the size of the second opening 35, so that the diameter of the second shaft hole 34 is reduced and the inner wall is tightly fitted and secured to the outer wall of the grip handle 2, thereby achieving a fixed installation between the grip handle 2 and the coupling 3.

[0069] The wrench 1 and the handle 2 are detachably mounted on the same coupling 3, allowing the wrench 1 to be removed from the coupling 3 to replace it with different models, thereby increasing the adaptability of the oil nozzle cleaning tool. Furthermore, the wrench 1 and the handle 2 are fixedly mounted via the coupling 3, improving the stability of the connection between them and increasing the structural strength of the oil nozzle cleaning tool.

[0070] The working principle of the nozzle disassembly and cleaning tool in this embodiment is as follows:

[0071] First, connect the wrench 1 and the handle 2 to the same coupling 3.

[0072] Then, the nozzle is removed from the nozzle sleeve. Specifically, when the connecting part of the nozzle is connected to the nozzle sleeve by threads, a sleeve 12 matching the model of the nozzle's disassembly part is selected. The sleeve 12 is fitted onto the disassembly part, and then the handle 2 is held with both hands and rotated around the central axis of the connecting rod 11 to rotate the sleeve 12 and the disassembly part of the nozzle, thereby removing the nozzle from the nozzle sleeve. When the connecting part of the nozzle is interference-fitted with the nozzle sleeve, the second magnetic element 24 is used to magnetically attract the metal disassembly part of the nozzle, and the magnetic force of the second magnetic element 24 is gradually increased until the nozzle is pulled off the nozzle sleeve. Since the sleeve 12 also contains a first magnetic element 13, which can magnetically attract the metal disassembly part of the nozzle, the nozzle is prevented from detaching from the sleeve 12 during the disassembly and assembly process.

[0073] Then, the disassembled nozzle can be cleaned. Remove the cleaning hook 4, cleaning brush or tweezers from the handle 2 and clean the nozzle; after cleaning, reinstall the cleaning hook 4, etc., onto the handle 2 to prevent loss.

[0074] Similarly, the nozzle cleaning and disassembly tool can be used to clean or replace the nozzle and install it onto the nozzle sleeve. When the pre-tightening force of the nozzle reaches the preset value, if you continue to tighten the handle 2, the part of the connecting rod 11 near the stress hole 14 will undergo torsional deformation, preventing the nozzle from being damaged due to excessive force.

[0075] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
