Description

Technical Field

[0001] This application relates to the field of disassembly and assembly tools, and in particular to an auxiliary device for disassembling and assembling couplings. Background Technology

[0002] Couplings, as key components connecting two shafts in different mechanisms to achieve common rotation and transmit torque, have extremely wide applications. In actual production and equipment maintenance, coupling disassembly is a frequent and important operation. In specific scenarios such as wind power equipment, couplings often have considerable weight, further increasing the difficulty of disassembly.

[0003] Currently, the commonly used tools and methods for disassembling couplings have many drawbacks: during the disassembly process, the coupling needs to be lifted by manpower and lifting equipment throughout the entire process, and alignment operations must be performed. Controlling the horizontal axial movement of the coupling by coordinating lifting equipment and manual labor makes it difficult to control the angle and direction of the coupling, the operation is difficult, and there are safety hazards. Utility Model Content

[0004] Therefore, it is necessary to provide a coupling assembly and disassembly auxiliary device to address the problem that conventional technologies, which rely on lifting equipment and manual labor to control the horizontal axial movement of couplings, are not convenient for controlling the angle and direction of the couplings.

[0005] This application provides a coupling disassembly and assembly auxiliary device, comprising: a support slide rail, which is horizontally arranged and fixed above the coupling, and the extension direction of the support slide rail is parallel to the disassembly and assembly direction of the coupling; a sliding assembly, which is slidably connected to the support slide rail along the extension direction of the support slide rail; and a lifting component, which is configured to connect the sliding assembly and the coupling.

[0006] According to one embodiment of this application, the sliding component includes a sliding sleeve that is slidably fitted onto the outside of the support slide rail.

[0007] According to one embodiment of this application, the sliding assembly further includes a first limiting ring and a second limiting ring fixed to both ends of the sliding sleeve, and the connection position between the lifting component and the sliding sleeve is located between the first limiting ring and the second limiting ring.

[0008] According to one embodiment of this application, the sliding assembly further includes a rolling element, which is rotatably disposed inside the sliding sleeve and rolls in contact with the outer wall of the supporting slide rail.

[0009] According to one embodiment of this application, the rolling elements are arranged in multiple rows around the circumference of the sliding sleeve, and the multiple rolling elements in each row are arranged sequentially at intervals along the axial direction of the sliding sleeve.

[0010] According to one embodiment of this application, one end of the support slide rail is fixed, and the other end is provided with a limiting member.

[0011] According to one embodiment of this application, the limiting member is detachably connected to the supporting slide rail.

[0012] According to one embodiment of this application, the two ends of the support slide rail are respectively provided with external threads, one end of the support slide rail is threadedly fixed to the support structure, and the other end is threadedly connected to the limiting member.

[0013] According to one embodiment of this application, the limiting member includes a limiting nut and an anti-loosening nut, both of which are threadedly connected to the support slide rail.

[0014] According to one embodiment of this application, the lifting component includes an annular sling, which is sleeved on the outside of the sliding assembly and the coupling.

[0015] The aforementioned coupling assembly / disassembly auxiliary device features a horizontally fixed support rail, providing stable support for the sliding component and restricting its direction of movement. After connecting the sliding component and the coupling via a lifting device, the coupling can be moved by sliding the sliding component along the support rail, thus assisting in the assembly / disassembly of the coupling. The support provided by this device ensures more stable movement of the coupling, eliminating the need for operators to exert effort in controlling its height and angle. This effectively reduces operational difficulty and labor costs, and also prevents the coupling from falling during assembly / disassembly, improving operational safety. Attached Figure Description

Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Figure 1 This is a schematic diagram of the overall structure of a coupling disassembly and assembly auxiliary device provided in one embodiment of this application. Figure 1 Lifting components are not shown. Figure 2 A schematic diagram of the lifting component, sliding assembly, and coupling cooperation structure of the coupling disassembly and assembly auxiliary device provided in an embodiment of this application.

[0037] Combination Figure 1 and Figure 2 An embodiment of this application provides a coupling assembly / disassembly auxiliary device, including a support slide rail 100, a sliding assembly 200, and a lifting component 700. The support slide rail 100 is horizontally arranged and fixed above the coupling 800, and the extending direction of the support slide rail 100 is parallel to the assembly / disassembly direction of the coupling 800. The sliding assembly 200 is slidably connected to the support slide rail 100 along the extending direction of the support slide rail 100. The lifting component 700 is configured to connect the sliding assembly 200 and the coupling 800.

[0038] The support slide rail 100 is horizontally fixed above the coupling 800, and its extension direction is parallel to the disassembly and assembly direction of the coupling 800. The disassembly and assembly direction of the coupling 800 is circumferential, and the coupling 800 is axially horizontal during disassembly and assembly. The support slide rail 100 provides a stable sliding track for the sliding assembly 200; the sliding assembly 200 is slidably connected to the support slide rail 100 and can move smoothly along the extension direction of the support slide rail 100; one end of the lifting component 700 is connected to the sliding assembly 200, and the other end is connected to the coupling 800, transferring the weight of the coupling 800 to the sliding assembly 200 and the support slide rail 100.

[0039] The horizontal fixation of the support rail 100 provides stable support for the coupling 800, restricting its movement direction to be consistent with the disassembly and assembly direction, and preventing the coupling 800 from swaying back and forth during movement. The movement of the coupling 800 is achieved by the sliding component 200 sliding along the support rail 100, eliminating the need for manual labor or lifting equipment to lift and align it throughout the process. Operators do not need to exert effort to stabilize the coupling 800, reducing the difficulty of operation. The connection of the lifting component 700 enables the coupling 800 and the sliding component 200 to move synchronously, ensuring a smooth movement process, reducing the risk of collision caused by the shaking of the coupling 800, and thus improving operational safety.

[0040] In some embodiments, the sliding component 200 includes a sliding sleeve 210, which is slidably fitted onto the outside of the support rail 100.

[0041] The sliding sleeve 210 has a cylindrical structure, and its inner wall is adapted to the outer wall of the support slide rail 100. The sliding sleeve 210 can slide freely along the axial direction of the support slide rail 100. The length of the sliding sleeve 210 is set according to the size of the coupling 800 to ensure stable support for the lifting component 700.

[0042] Optionally, the entire support slide rail 100 and slide sleeve 210 are made of stainless steel. Stainless steel has excellent corrosion resistance and can resist the erosion of oil, water vapor and corrosive media in the industrial environment, reducing component damage caused by rust and extending the service life of the device. At the same time, stainless steel has high strength and hardness, and is not easily deformed or worn when subjected to the pressure and friction of the coupling 800. It can maintain structural stability and performance for a long time, and its smooth surface can reduce sliding friction resistance, making sliding smoother and improving work efficiency.

[0043] The sliding fit between the sliding sleeve 210 and the supporting slide rail 100 provides precise guidance for the movement of the coupling 800, ensuring that the coupling 800 always moves in the disassembly and assembly direction and avoiding deviation. The cylindrical structure of the sliding sleeve 210 can evenly wrap around the supporting slide rail 100, dispersing the pressure transmitted by the coupling 800, reducing deformation caused by excessive local stress on the supporting slide rail 100, and ensuring the long-term stability of the device. The sliding characteristics of the sliding sleeve 210 reduce the resistance when the coupling 800 moves, making it easier for operators to control the moving speed and further improving work efficiency.

[0044] Optionally, the support slide rail 100 is a cylindrical rod, and the sliding sleeve 210 is a cylindrical structure adapted to the support slide rail 100. The support slide rail 100 adopts a cylindrical rod structure with a smooth outer wall and no sharp edges. The diameter of the rod is set according to the weight of the coupling 800 to ensure sufficient load-bearing capacity. The sliding sleeve 210 is a cylindrical structure with its inner wall adapted to the outer wall of the cylindrical rod, and an appropriate gap is left between them to ensure that the sliding sleeve 210 can slide freely along the axial direction of the cylindrical rod. The length of the sliding sleeve 210 matches the diameter of the cylindrical rod to ensure stability during the sliding process.

[0045] The smooth surface of the cylindrical rod and the inner wall of the cylindrical sleeve 210 reduce the sliding friction resistance between them, making the sliding of the sleeve 210 smoother. Operators do not need to apply excessive force to move the sleeve 210 and the coupling 800, reducing the difficulty of operation. The cylindrical structure distributes the force evenly. As a cylindrical rod, the support rail 100 can distribute the pressure evenly along the circumference when bearing the weight of the coupling 800, making it less prone to bending or deformation and ensuring the stability of the support. The cylindrical structure of the sleeve 210 can fully enclose the cylindrical rod, preventing the sleeve 210 from tilting or shifting during sliding, ensuring that the coupling 800 always moves along the axial direction of the support rail 100, reducing the risk of equipment collision due to unstable movement. At the same time, this structure has strong adaptability. The processing technology of the cylindrical rod and the cylindrical sleeve 210 is relatively simple, which is convenient for mass production. Moreover, the fitting accuracy of the two is easy to control, which can ensure the consistency and reliability of the device.

[0046] Combination Figure 2 and Figure 3 In some embodiments, the sliding assembly 200 further includes a first limiting ring 220 and a second limiting ring 230 fixed to both ends of the sliding sleeve 210, and the connection position between the lifting component 700 and the sliding sleeve 210 is located between the first limiting ring 220 and the second limiting ring 230.

[0047] In this embodiment, the first limiting ring 220 and the second limiting ring 230 are respectively fixed to both ends of the sliding sleeve 210, and are integral with the sliding sleeve 210 or fixedly connected by welding or other means. The outer diameter of the first limiting ring 220 and the second limiting ring 230 is larger than the outer diameter of the sliding sleeve 210, and the connection point between the lifting component 700 and the sliding sleeve 210 is located between the two limiting rings.

[0048] Since the connection point of the lifting component 700 is located between the two limiting rings, the limiting rings can block the lifting component 700, preventing the lifting component 700 from falling off the sliding sleeve 210 during movement, ensuring that the coupling 800 and the sliding component 200 always remain connected, and reducing safety hazards caused by connection failure.

[0049] Combination Figure 3 and Figure 4 In some embodiments, the sliding assembly 200 further includes a rolling element 240, which is rotatably disposed inside the sliding sleeve 210 and rolls in contact with the outer wall of the supporting slide rail 100.

[0050] The rolling element 240 is a ball or roller structure. The rolling element 240 is rotatably embedded in the inner wall of the sliding sleeve 210. Part of its spherical surface protrudes from the inner wall of the sliding sleeve 210 and contacts the outer wall of the supporting slide rail 100. The rolling element 240 can be made of high-strength metal to withstand the pressure transmitted by the coupling 800.

[0051] The rolling element 240 converts the sliding friction between the sliding sleeve 210 and the support rail 100 into rolling friction. The resistance of rolling friction is much smaller than that of sliding friction, making the sliding sleeve 210 slide more smoothly along the support rail 100. The operator only needs to apply a small force to move the sliding sleeve 210, reducing physical exertion. The contact between the rolling element 240 and the support rail 100 is point contact, which can evenly distribute the pressure on the sliding sleeve 210, avoiding jamming or displacement of the sliding sleeve 210 due to uneven friction, ensuring that the coupling 800 moves smoothly along the axial direction, and reducing potential damage to the equipment.

[0052] In some embodiments, multiple rows of rolling elements 240 are arranged circumferentially around the sleeve 210, and multiple rolling elements 240 in each row are arranged sequentially at intervals along the axial direction of the sleeve 210.

[0053] In this embodiment, at least three rows of rolling elements 240 are evenly arranged around the circumference of the sliding sleeve 210. Multiple rolling elements 240 in each row are arranged at equal intervals along the axial direction of the sliding sleeve 210. The positions of the rolling elements 240 in each row correspond one-to-one, forming an all-round wrapping of the support slide rail 100.

[0054] Multiple rows of rolling elements 240 contact the support slide rail 100 at multiple positions around the circumference of the sliding sleeve 210, which can more evenly distribute the weight of the sliding sleeve 210 and the coupling 800, prevent the sliding sleeve 210 from tilting due to uneven force, and ensure that the sliding sleeve 210 always slides along the axial direction of the support slide rail 100. The rolling elements 240 arranged axially at intervals in each row can continuously provide rolling support during the movement of the sliding sleeve 210, reduce the wear of individual rolling elements 240, extend the service life of the rolling elements 240, and at the same time ensure the continuity and stability of the sliding process.

[0055] In some embodiments, one end of the support slide rail 100 is fixed, and the other end is provided with a limiting member 300.

[0056] In this embodiment, one end of the support slide rail 100 is fixed to the external support structure by means of threaded connection, welding or other means, and the other end is equipped with a limiting member 300. The size of the limiting member 300 is larger than the inner diameter of the sliding component 200, which can prevent the sliding component 200 from detaching from that end of the support slide rail 100.

[0057] The fixing of one end of the support slide rail 100 provides a stable foundation for the entire device, preventing the support slide rail 100 from shaking or shifting during the movement of the coupling 800, thus ensuring the reliability of the support. The limiting member 300 at the other end can limit the maximum sliding stroke of the sliding component 200, keeping the movement range of the coupling 800 within a safe range, preventing the coupling 800 from detaching from the support due to excessive movement, reducing the risk of collision with the ground or other equipment, and improving the safety of operation.

[0058] In some embodiments, the limiting member 300 is detachably connected to the support slide rail 100.

[0059] In this embodiment, the limiting member 300 is installed at the end of the support slide rail 100 by means of detachable connection such as threaded connection or snap-fit ​​connection. After disassembly, the sliding component 200 can be taken out or installed from that end of the support slide rail 100.

[0060] The detachable design of the limiting component 300 facilitates the installation and replacement of the sliding component 200. When the sliding component 200 is worn or malfunctions, the limiting component 300 can be quickly disassembled for repair or replacement, reducing maintenance costs. At the same time, according to the disassembly and assembly requirements of different couplings 800, the effective length of the support slide rail 100 can be adjusted by disassembling the limiting component 300, enhancing the versatility of the device and adapting to more application scenarios.

[0061] In some embodiments, the two ends of the support slide rail 100 are respectively provided with external threads, one end of the support slide rail 100 is threadedly fixed to the support structure, and the other end is threadedly connected to the limiting member 300.

[0062] In this embodiment, external threads are machined on both outer sides of the support slide rail 100. The external thread at one end engages with the internal thread on the external support structure to achieve fixation, and the external thread at the other end engages with the internal thread of the limiting member 300 to achieve installation of the limiting member 300.

[0063] The threaded connection has high connection strength, which can ensure a stable connection between the support slide rail 100 and the external support structure and the limiting member 300, and prevent the connection from loosening due to vibration and other factors during operation, thus ensuring the stability of the device. By rotating the support slide rail 100 or the limiting member 300, the fixed position of the support slide rail 100 and the position of the limiting member 300 can be precisely adjusted, which is convenient for fine-tuning according to the actual position of the coupling 800, improving the installation accuracy of the device, and ensuring that the moving direction of the coupling 800 is completely consistent with the disassembly and assembly direction.

[0064] In some embodiments, the limiting member 300 includes a limiting nut 310 and an anti-loosening nut 320, both of which are threadedly connected to the support slide rail 100.

[0065] In this embodiment, both the limiting nut 310 and the anti-loosening nut 320 are engaged with the external thread of one end of the supporting slide rail 100. The limiting nut 310 is located on the side closer to the sliding component 200, and the anti-loosening nut 320 is located on the side of the limiting nut 310 away from the sliding component 200. The two are locked together by tightening each other.

[0066] The limiting nut 310 can directly block the sliding component 200, limiting its maximum sliding stroke; after the anti-loosening nut 320 and the limiting nut 310 are locked together, the limiting nut 310 can be prevented from loosening under the influence of vibration and other factors, ensuring the durability of the limiting effect; the double nut setting forms a double protection, even if one nut is slightly loose, the other nut can still play a limiting role, further improving the reliability of the device.

[0067] In some embodiments, the lifting component 700 includes an annular sling sleeved around the outside of the sliding assembly 200 and the coupling 800.

[0068] In this embodiment, the annular sling is made of high-strength flexible material. One end of the sling is sleeved on the outside of the sliding component 200, and the other end is sleeved on the outside of the coupling 800. The length of the sling can be adjusted according to the position of the coupling 800 to ensure that the coupling 800 is in a horizontal state.

[0069] The flexibility of the ring sling can adapt to the shape of the coupling 800 and the sliding component 200, making the connection tighter and preventing it from falling off during movement. The sling sleeve connection method can distribute the lifting force, reduce the local pressure on the coupling 800 and the sliding component 200, and prevent the components from deforming or being damaged due to concentrated force. The ring structure makes the force on the sling more even, ensuring that the coupling 800 remains horizontal during movement, reducing the risk of tilting, and further improving the stability and safety of the operation.

[0070] Combination Figure 5 In some embodiments, the coupling disassembly and assembly auxiliary device further includes a locking ring 400 and at least one radial locking mechanism 500 disposed on the locking ring 400. The locking ring 400 is sleeved on the outside of the support slide rail 100 and fixedly connected to one end of the slide sleeve 210. The radial locking mechanism 500 includes an adjusting screw 510, a positioning block 520 and a knob 530. The adjusting screw 510 is threadedly connected to a threaded hole on the side wall of the locking ring 400, one end of which extends into the inside of the locking ring 400 and is rotatably connected to the positioning block 520, and the other end is located on the outside of the locking ring 400 and is fixedly connected to the knob 530.

[0071] Rotating the knob 530 to adjust the screw 510 can push the positioning block 520 to move radially, so that the arc-shaped surface of the positioning block 520 fits and presses against the outer wall of the support slide rail 100, thereby locking the position of the slide sleeve 210.

[0072] In some embodiments, the coupling disassembly and assembly auxiliary device further includes a dynamic locking mechanism 600, which includes a locking rod 610, a locking block 620, and a return spring 630. The side wall of the locking ring 400 has a through hole that extends through the inside and outside. The locking rod 610 passes through the through hole, and its end located on the outside of the locking ring 400 has a pressing part, while its end located on the inside of the locking ring 400 is connected to the locking block 620. The end of the locking block 620 has an arc-shaped locking surface that is adapted to the outer wall of the support slide rail 100, and the arc-shaped locking surface has anti-slip texture. The return spring 630 is sleeved on the part of the locking rod 610 located on the outside of the locking ring 400, with one end abutting against the outer wall of the locking ring 400 and the other end abutting against the pressing part. In its natural state, the elastic force of the return spring 630 keeps the locking block 620 separated from the outer wall of the support slide rail 100.

[0073] When it is necessary to pause the movement of the coupling 800, pressing the pressing part of the locking rod 610 can cause the locking block 620 to fit against the outer wall of the support slide rail 100. The anti-slip texture increases the friction to achieve immediate fixation of the slide sleeve 210, preventing the slide sleeve 210 from sliding due to accidental force and improving operational safety. After releasing the pressing part, the elastic force of the return spring 630 causes the locking block 620 to automatically reset, without affecting the normal sliding of the slide sleeve 210, making operation convenient. This mechanism allows the operator to control the position of the coupling 800 at any time during disassembly, facilitating intermediate operations such as alignment and inspection, and further reducing the difficulty of operation.

[0074] Understandably, when it is necessary to temporarily lock the position of the sliding sleeve 210, the locking operation can be performed through the dynamic locking mechanism 600, while when it is necessary to lock the position of the sliding sleeve 210 for a long time, the locking operation can be performed through the radial locking mechanism 500. The dynamic locking mechanism 600 and the radial locking mechanism 500 work together to be applicable to different application scenarios and are more convenient to use.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
