Description

Technical Field

[0001] The utility model relates to a tool design that relates to the technical field, in particular to a disassembly tool. Background Art

[0002] In the field of wind power generation, the normal operation of wind turbine generators is crucial to the efficiency and reliability of the entire wind power generation system. As a common wind power generation equipment, the regular maintenance and replacement of the generator bearings of the Goldwind 750 wind turbine is one of the key links to ensure the long-term stable operation of the equipment. In the process of replacing the generator bearings, the front positioning frame of the bearing needs to be disassembled. However, there is currently a lack of special disassembly tooling for the disassembly of the front positioning frame of the 750 wind turbine generator bearing, which leads to many difficulties in actual operation.

[0003] In the prior art, a tripod puller and a spray gun are usually used for disassembly. However, due to the small spacing between the front positioning frame of the bearing and the bearing, a high-torque puller cannot be effectively inserted, and a low-torque puller cannot provide sufficient pulling force. In addition, during the use of the tripod puller, its connecting bolts are prone to bending and breaking, which poses a great operational risk. These problems not only increase the difficulty and time cost of maintenance work, but may also cause equipment damage and even endanger the safety of operators.

[0004] Therefore, there is an urgent need for a special disassembly tool that can efficiently and safely disassemble the front positioning frame of the bearing when replacing the generator bearing, so as to improve the disassembly process, avoid equipment damage, and better ensure personal safety.

[0005] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only used to understand the background of the concept of the present application, and does not indicate or imply that it contains information of the prior art. Utility Model Content

[0006] Based on this, it is necessary to provide a disassembly tool to address the above problems.

[0007] A disassembly tool, comprising:

[0008] A chuck is used to clamp between the bearing and the bearing positioning frame mounted on the shaft column of the generator;

[0009] A fixed rod assembly, one end of which is fixed to the chuck;

[0010] A support seat, the other end of the fixing rod assembly is fixed to the support seat, the support seat is located on a side of the chuck close to the bearing positioning frame and is spaced apart from the chuck to form an accommodating space for the end of the shaft column to extend into; and

[0011] A power telescopic device, which is used to abut between the end face of the shaft column and the support seat. The power telescopic device can extend and drive the support seat to drive the fixed rod assembly and the chuck to move in a direction away from the bearing, so that the bearing positioning frame can slide on the outer circumferential surface of the shaft column in a direction away from the bearing under the clamping of the chuck until the bearing positioning frame falls off the shaft column.

[0012] The above-mentioned disassembly tool can at least achieve the following beneficial effects: the disassembly tool can be applied to various scenarios where the bearing locating frame on the shaft column needs to be disassembled, so as to facilitate the subsequent disassembly and replacement of the bearing on the shaft column, including but not limited to the disassembly of the bearing locating frame set on the shaft column of the Goldwind 750 wind turbine generator. When used specifically, the chuck can be clamped between the bearing set on the shaft column of the generator and the bearing locating frame to firmly fix the bearing locating frame, avoiding the problem that the traditional tripod puller is difficult to hang in or the torque is insufficient during operation, thereby greatly improving the disassembly efficiency. The fixed rod assembly is connected between the support seat and the chuck, and the power telescopic device can accurately control the extension and contraction, so that the support seat drives the fixed rod assembly and the chuck to move in the direction away from the bearing, so that the bearing locating frame can slide smoothly on the outer peripheral surface of the shaft column until it falls off the shaft column. This precise control avoids the errors and damages caused by improper operation in the traditional method, and the design of the fixed rod assembly and the support seat makes the entire disassembly process more stable, avoids the risk of easy bending and breaking of the connecting bolts, and reduces the possibility of equipment damage and operator injury. The disassembly tooling has a simple structure and is easy for operators to use. It does not require complicated operating steps and special skills, can greatly reduce the labor intensity of maintenance personnel, improves work efficiency, and is also conducive to avoiding long-term equipment downtime.

[0013] In one embodiment, the edge of the chuck is recessed inward to form a clamping groove, and the chuck is clamped between the bearing and the bearing positioning frame through the clamping groove, and the chuck abuts against the side of the bearing positioning frame close to the bearing. The clamping groove provided on the chuck can provide an escape space to avoid the shaft column, so that the physical structure of the chuck can extend between the bearing and the bearing positioning frame, and abut against the side of the bearing positioning frame facing away from the support seat. When the chuck is subsequently pulled by the fixed rod assembly, the chuck can also drive the bearing positioning frame to slide along the axial direction of the shaft column until the bearing positioning frame slides out from the end of the shaft column, thereby realizing the disassembly of the bearing positioning frame.

[0014] In one of the embodiments, the clamping groove is U-shaped. By designing the clamping groove into a U-shaped structure, it is advantageous for the chuck to be more tightly mounted on the shaft column and the bearing positioning frame through the clamping groove. The bottom of the U-shaped clamping groove is roughly semicircular, which fits the cross-section of the shaft column, which is usually circular, improves the stability and reliability of the connection, and can also effectively reduce errors during the installation process. Such a structural design also simplifies the installation and disassembly process, improves assembly efficiency and maintenance convenience. In short, the design of the U-shaped clamping groove not only improves the overall performance of the device, but also provides users with a more convenient operating experience.

[0015] In one embodiment, a positioning rib is convexly provided on the groove wall of the clamping groove, and the positioning rib is used to clamp between the bearing and the bearing positioning frame, and the positioning rib abuts against the side of the bearing positioning frame close to the bearing. The positioning rib on the chuck abuts against the side of the bearing positioning frame close to the bearing, that is, the positioning rib abuts against the side of the bearing positioning frame facing away from the support seat, and when the power telescopic device is extended, the chuck slides on the shaft column in a direction away from the bearing driven by the fixed rod assembly and the support seat, and the positioning rib will also drive the bearing positioning frame abutted thereto to slide on the outer peripheral surface of the shaft column together, until the bearing positioning frame slides off the end of the shaft column.

[0016] In one embodiment, the positioning rib is extended in the holding groove to form a U-shape. The U-shaped positioning rib is structurally compatible with the shaft column and the bearing positioning frame, which not only improves the stability and reliability of the connection, but also effectively reduces the error during the installation process, and also increases the contact area between the positioning rib and the bearing positioning frame, ensuring that the chuck and the bearing positioning frame can evenly distribute the pressure when subjected to force, so that the chuck can more effectively drive the movement of the bearing positioning frame, and can also reduce the local stress concentration of the chuck, thereby extending the service life of the chuck and the disassembly tooling as a whole.

[0017] In one embodiment, the thickness of the positioning rib is less than the spacing between the bearing and the bearing locating frame. Such a structural setting means that the positioning rib can be easily inserted between the bearing and the bearing locating frame, which not only simplifies the installation process, enables the chuck to cooperate with the bearing and the bearing locating frame more conveniently, but also reduces the risk of component damage caused by installation difficulties. Specifically, the smaller thickness enables the positioning rib to smoothly slide into the gap between the bearing and the bearing locating frame during installation, avoiding wear and deformation that may be caused by forced installation. This design ensures that the chuck does not require too much effort and complicated operating steps during installation, thereby improving assembly efficiency and convenience of operation. In addition, the positioning rib can provide sufficient fixing force after being inserted, ensuring that the chuck remains stable during operation and will not loosen or fall off due to vibration or external force. At the same time, such a design also has a certain self-adjustment function, allowing for small installation errors, thereby further improving assembly accuracy and consistency. The presence of the positioning rib not only enhances the connection strength between the chuck and the bearing locating frame, but also plays a role in positioning and guiding to a certain extent, ensuring that the chuck is in the correct position after installation. In short, by designing the thickness of the retaining rib to be smaller than the distance between the bearing and the bearing locating frame, not only the convenience and safety of installation are improved, but also the overall stability and reliability of the device are enhanced, and the assembly efficiency and service life are significantly improved.

[0018] In one embodiment, the clamping groove includes a first clamping groove and a second clamping groove which are sequentially connected along the thickness direction of the chuck, the first clamping groove is used to contact the outer peripheral surface of the bearing locating frame to carry the bearing locating frame, and the clamping rib is convexly provided on the groove wall of the second clamping groove. The first clamping groove can be used to contact the outer peripheral surface of the bearing locating frame, providing stable support and load-bearing capacity, and the clamping rib in the second clamping groove can be clamped between the bearing and the bearing locating frame, ensuring a reliable connection between the chuck, the bearing and the bearing locating frame.

[0019] In one embodiment, the width of the second retaining groove is smaller than the width of the first retaining groove.

[0020] In one embodiment, the width of the second clamping groove is greater than the diameter of the shaft column. Such a structural setting can be considered that the width of the second clamping groove is slightly greater than the diameter of the shaft column, that is, the width of the second clamping groove has a certain margin, which allows the chuck to be clamped to the outer peripheral surface of the shaft column more easily, thereby improving the convenience of installation.

[0021] In one embodiment, the power telescopic device is a jack. The power telescopic device is arranged between the support seat and the end face of the end of the shaft column. The jack is telescopic and can provide sufficient force to make the support seat away from the end face of the end of the shaft column, and the chuck and the fixing rod assembly will slide on the shaft column together under the drive of the support seat, and the chuck can also drive the bearing positioning frame it abuts to slide on the outer peripheral surface of the shaft column in a direction away from the bearing until the bearing positioning frame slides off the end of the shaft column.

[0022] In one embodiment, the fixing rod assembly includes a plurality of fixing rods, and the two ends of any fixing rod are respectively fixed to the chuck and the support seat, and the plurality of fixing rods are spaced around the chuck. The plurality of fixing rods are spaced around the chuck, so that the pulling force of the support seat can be more evenly and effectively transmitted to the chuck through the plurality of fixing parts, and the problem of deformation of the chuck due to excessive local stress can be avoided.

[0023] In one embodiment, the chuck is provided with a plurality of first threaded holes arranged at intervals, and one end of each of the fixing rods is threadedly connected to one of the first threaded holes to be fixed to the chuck. Such a structural setting is convenient for disassembly between the chuck and the fixing rod, and can also adjust the relative position between the fixing rod and the chuck by rotating the fixing rod, thereby adjusting the distance between the chuck and the support seat to adapt to different working scenarios.

[0024] In one embodiment, the support seat is provided with a plurality of second threaded holes arranged at intervals, and the other end of each of the fixing rods is threadedly connected to one of the second threaded holes to be fixed to the support seat. Such a structural setting is convenient for disassembly between the support seat and the fixing rod, and on the other hand, the relative position between the fixing rod and the support seat can be adjusted by rotating the fixing rod, thereby adjusting the distance between the chuck and the support seat to adapt to different working scenarios.

[0033] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0034] See also Figure 1 , Figure 2 and Figure 3In some embodiments, the present application provides a disassembly tool 10 , which includes a chuck 100 , a fixing rod assembly 200 , a support seat 300 , and a power telescopic device 400 . Among them, the chuck 100 is used to clamp between the bearing 30 and the bearing positioning frame 40 mounted on the shaft column 20 of the generator; one end of the fixed rod assembly 200 is fixed to the chuck 100; the other end of the fixed rod assembly 200 is fixed to the support seat 300, and the support seat 300 is located on the side of the chuck 100 close to the bearing positioning frame 40 and is spaced from the chuck 100 to form an accommodating space for the end of the shaft column 20 to extend into; the power telescopic device 400 is used to abut between the end face of the shaft column 20 and the support seat 300, and the power telescopic device 400 can extend and drive the support seat 300 to drive the fixed rod assembly 200 and the chuck 100 to move in a direction away from the bearing 30, so that the bearing positioning frame 40 can slide on the outer peripheral surface of the shaft column 20 in a direction away from the bearing 30 under the clamping of the chuck 100 until the bearing positioning frame 40 falls off from the shaft column 20.

[0035] The above-mentioned disassembly tool 10 can at least achieve the following beneficial effects: the disassembly tool 10 can be applied to various scenarios where the bearing locating frame 40 on the shaft column 20 needs to be disassembled, so as to facilitate the subsequent disassembly and replacement of the bearing 30 on the shaft column 20, including but not limited to the disassembly of the bearing locating frame 40 sleeved on the shaft column 20 of the Goldwind 750 wind turbine generator. In specific use, taking the generator as an example, the outer peripheral surface of the shaft column 20 of the generator is sleeved with a bearing 30 and a bearing locating frame 40, which can be clamped between the bearing 30 and the bearing locating frame 40 by a chuck 100, so as to be able to firmly fix the bearing locating frame 40, avoiding the problem of the traditional tripod puller being difficult to hang in or insufficient torque during operation, thereby greatly improving the disassembly efficiency. The fixed rod assembly 200 is connected between the support seat 300 and the chuck 100, and the power telescopic device 400 can accurately control the extension and contraction, so that the support seat 300 drives the fixed rod assembly 200 and the chuck 100 to move in a direction away from the bearing 30, so that the bearing positioning frame 40 can slide smoothly on the outer peripheral surface of the shaft column 20 driven by the chuck 100 until it falls off the shaft column 20. This precise control avoids errors and damages caused by improper operation in traditional methods, and the design of the fixed rod assembly 200 and the support seat 300 makes the entire disassembly process more stable, avoids the risk of easy bending and breaking of the connecting bolts, and reduces the possibility of equipment damage and operator injury. The disassembly tool 10 has a simple structure and is easy for operators to use. It does not require complicated operating steps and special skills. It can greatly reduce the labor intensity of maintenance personnel, improve work efficiency, and is also conducive to avoiding long-term equipment shutdown.

[0036] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the edge of the chuck 100 is recessed inward to form a clamping groove 120, and the chuck 100 is clamped between the bearing 30 and the bearing positioning frame 40 through the clamping groove 120, and the chuck 100 abuts against the side of the bearing positioning frame 40 close to the bearing 30. The clamping groove 120 provided on the chuck 100 can provide an escape space to avoid the shaft column 20, so that the physical structure of the chuck 100 can extend between the bearing 30 and the bearing positioning frame 40, and abut against the side of the bearing positioning frame 40 facing away from the support seat 300. When the chuck 100 is subsequently pulled by the fixing rod assembly 200, the chuck 100 can also drive the bearing positioning frame 40 to slide along the axial direction of the shaft column 20, until the bearing positioning frame 40 slides out from the end of the shaft column 20, thereby realizing the disassembly of the bearing positioning frame 40.

[0037] More specifically, if Figure 1 , Figure 2 and Figure 4 As shown, in some of the embodiments, the clamping groove 120 is U-shaped. By designing the clamping groove 120 into a U-shaped structure, it is advantageous for the chuck 100 to be more tightly mounted on the shaft column 20 and the bearing positioning frame 40 through the clamping groove 120. The bottom of the U-shaped clamping groove 120 is roughly semicircular, which fits the cross-section of the shaft column 20, which is usually circular, thereby improving the stability and reliability of the connection, and can also effectively reduce errors during the installation process. Such a structural design also simplifies the installation and disassembly process, and improves assembly efficiency and maintenance convenience. In short, the design of the U-shaped clamping groove 120 not only improves the overall performance of the device, but also provides users with a more convenient operating experience.

[0038] More specifically, if Figure 3 and Figure 4 As shown, in some embodiments, a positioning convex rib 130 is convexly provided on the groove wall of the clamping groove 120, and the positioning convex rib 130 is used to be clamped between the bearing 30 and the bearing positioning frame 40, and the positioning convex rib 130 abuts against the side of the bearing positioning frame 40 close to the bearing 30. The positioning convex rib 130 on the chuck 100 abuts against the side of the bearing positioning frame 40 close to the bearing 30, that is, the positioning convex rib 130 abuts against the side of the bearing positioning frame 40 facing away from the support seat 300. When the power telescopic device 400 is extended, the chuck 100 slides on the shaft column 20 in a direction away from the bearing 30 driven by the fixed rod assembly 200 and the support seat 300, and the positioning convex rib 130 also drives the bearing positioning frame 40 abutted thereto to slide on the outer peripheral surface of the shaft column 20 together, until the bearing positioning frame 40 slides off from the end of the shaft column 20.

[0039] More specifically, if Figure 4 As shown, in some embodiments, the positioning rib 130 is extended in the holding groove 120 to be U-shaped. The U-shaped positioning rib 130 is structurally compatible with the shaft column 20 and the bearing positioning frame 40, which not only improves the stability and reliability of the connection, but also can effectively reduce the error during the installation process, and also increases the contact area between the positioning rib 130 and the bearing positioning frame 40, ensuring that the chuck 100 and the bearing positioning frame 40 can evenly distribute the pressure when subjected to force, so that the chuck 100 can more effectively drive the movement of the bearing positioning frame 40, and can also reduce the local stress concentration of the chuck 100, thereby extending the service life of the chuck 100 and the disassembly tool 10 as a whole.

[0040] More specifically, if Figure 3 As shown, in some embodiments, the thickness of the positioning rib 130 is less than the spacing between the bearing 30 and the bearing positioning frame 40. Such a structural setting means that the positioning rib 130 can be easily inserted between the bearing 30 and the bearing positioning frame 40, which not only simplifies the installation process, so that the chuck 100 can be more conveniently matched with the bearing 30 and the bearing positioning frame 40, but also reduces the risk of component damage caused by installation difficulties. Specifically, the smaller thickness enables the positioning rib 130 to smoothly slide into the gap between the bearing 30 and the bearing positioning frame 40 during installation, avoiding wear and deformation that may be caused by forced installation. This design ensures that the chuck 100 does not require too much effort and complicated operating steps during installation, thereby improving assembly efficiency and convenience of operation. In addition, the positioning rib 130 can provide sufficient fixing force after being inserted, ensuring that the chuck 100 remains stable during operation and will not loosen or fall off due to vibration or external force. At the same time, such a design also has a certain self-adjustment function, allowing for small installation errors, thereby further improving assembly accuracy and consistency. The presence of the positioning rib 130 not only enhances the connection strength between the chuck 100 and the bearing positioning frame 40, but also plays a role in positioning and guiding to a certain extent, ensuring that the chuck 100 is in the correct position after installation. In short, by designing the thickness of the positioning rib 130 to be smaller than the distance between the bearing 30 and the bearing positioning frame 40, not only the convenience and safety of installation are improved, but also the overall stability and reliability of the device are enhanced, and the assembly efficiency and service life are significantly improved.

[0041] See also Figure 5In some embodiments, the clamping groove 120 includes a first clamping groove 121120 and a second clamping groove 122120 which are sequentially connected along the thickness direction of the chuck 100, the first clamping groove 121120 is used to contact the outer peripheral surface of the bearing positioning frame 40 to carry the bearing positioning frame 40, and the clamping convex rib 130 is convexly provided on the groove wall of the second clamping groove 122120. Among them, the first clamping groove 121120 can be used to contact the outer peripheral surface of the bearing positioning frame 40, providing stable support and bearing capacity, and the clamping convex rib 130 in the second clamping groove 122120 can be clamped between the bearing 30 and the bearing positioning frame 40, ensuring a reliable connection between the chuck 100, the bearing 30 and the bearing positioning frame 40.

[0042] Further, in some embodiments, the width of the second holding groove 122120 is smaller than the width of the first holding groove 121120 .

[0043] Furthermore, in some embodiments, the width of the second clamping groove 122120 is greater than the diameter of the shaft column 20. Such a structural setting can be considered that the width of the second clamping groove 122120 is slightly greater than the diameter of the shaft column 20, that is, the width of the second clamping groove 122120 is somewhat redundant, which can make it easier for the chuck 100 to be clamped onto the outer peripheral surface of the shaft column 20, thereby improving the convenience during installation.

[0044] See also Figure 2 and Figure 3 In some embodiments, the power telescopic device 400 may be a jack. The power telescopic device 400 is disposed between the support seat 300 and the end surface of the end of the shaft column 20. The jack is telescopic and can provide sufficient force to move the support seat 300 away from the end surface of the end of the shaft column 20. The chuck 100 and the fixing rod assembly 200 will slide on the shaft column 20 under the drive of the support seat 300. The chuck 100 can also drive the bearing positioning frame 40 it abuts against to slide on the outer peripheral surface of the shaft column 20 in a direction away from the bearing 30 until the bearing positioning frame 40 slides off the end of the shaft column 20.

[0045] See also Figure 1 and Figure 2 In some embodiments, the fixing rod assembly 200 includes a plurality of fixing rods 210, and the two ends of any fixing rod 210 are respectively fixed to the chuck 100 and the support seat 300, and the plurality of fixing rods 210 are spaced around the chuck 100. The plurality of fixing rods 210 are spaced around the chuck 100, so that the tension of the support seat 300 can be more evenly and effectively transmitted to the chuck 100 through the plurality of fixing parts, and the problem of deformation of the chuck 100 due to excessive local stress can be avoided.

[0046] Specifically, Figure 1 and Figure 4 As shown, in some embodiments, a plurality of first threaded holes 110 are provided at intervals on the chuck 100, and one end of each of the fixing rods 210 is threadedly connected to one of the first threaded holes 110 to be fixed to the chuck 100. Such a structural setting facilitates the disassembly between the chuck 100 and the fixing rod 210 on the one hand, and on the other hand, the relative position between the fixing rod 210 and the chuck 100 can be adjusted by rotating the fixing rod 210, thereby adjusting the spacing between the chuck 100 and the support seat 300 to adapt to different working scenarios.

[0047] Specifically, Figure 1 and Figure 2 As shown, in some embodiments, the support seat 300 is provided with a plurality of second threaded holes 320 arranged at intervals, and the other end of each of the fixing rods 210 is threadedly connected to one of the second threaded holes 320 to be fixed to the support seat 300. Such a structural setting is convenient for disassembly between the support seat 300 and the fixing rod 210 on the one hand, and on the other hand, the relative position between the fixing rod 210 and the support seat 300 can be adjusted by rotating the fixing rod 210, thereby adjusting the spacing between the chuck 100 and the support seat 300 to adapt to different working scenarios.
