Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically to a disassembly tool. Background Technology

[0002] In the operation and maintenance of wind turbine generator sets, insulated gate bipolar transistor modules (hereinafter referred to as IGBT modules) need to be replaced periodically. IGBT modules are generally installed inside the generator set's cabinet, and removing them requires entirely manual operation. Specifically, one operator grasps the neutral copper busbar of the IGBT module with both hands and pulls it outwards, pulling the module about halfway out of the cabinet. Then, two operators work together to remove the IGBT module from the cabinet.

[0003] The cabinet interior has multiple layers of dustproof rubber strips that make close contact with the outer contour of the IGBT module, resulting in significant resistance when pulling it, making operation difficult, especially in low winter temperatures or when the rubber strips are deformed. Furthermore, due to limited workspace and the structure of the IGBT module itself, pulling the IGBT module can only be done by a single person, making the operation difficult, increasing the risk of injury and damage from falling components, and reducing work efficiency. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a disassembly fixture is provided. The disassembly fixture includes: a support assembly comprising a first leg, a second leg, and a support rod, the support rod being connected between the first leg and the second leg; a first support end formed at the end of the first leg away from the support rod for abutting against an external cabinet; and a second support end formed at the end of the second leg away from the support rod for abutting against an external cabinet; a movable member connected to the support rod and movable relative to the support rod in a predetermined direction; and a pull-out member connected to the movable member, the pull-out member having a limiting space for limiting the part to be disassembled, and a through-hole formed on the pull-out member for the part to be disassembled to pass through, the through-hole communicating with the limiting space.

[0005] The disassembly fixture provided in this application features a support component that abuts against the external cabinet, providing stable support for the disassembly process and reducing operational difficulty. The cooperation between the moving and pulling components allows for smoother mechanical pulling of the component to be disassembled, resulting in a more stable process. When applied to the disassembly of IGBT modules, the support component abuts against the external cabinet, providing support even in confined working spaces and a reliable force base for the pulling process. This eliminates the need for manual force from the operator to maintain balance during the pulling action. Combined with the smooth mechanical pulling of the moving and pulling components, IGBT modules can be disassembled even in spaces with limited space, reducing operational difficulty caused by space constraints and simplifying the disassembly process for higher efficiency.

[0006] For example, the movable member includes a movable rod and a rotating member. The movable rod is movably connected to the support rod, and the rotating member is connected between the movable rod and the pulling member. The pulling member is rotatable relative to the movable rod under the drive of the rotating member.

[0007] For example, the rotating component includes a fixed ring and a rotating ring connected to the pulling component. The fixed ring is connected to the moving rod, and the rotating ring is connected to the fixed ring and rotatable relative to the fixed ring along a rotation axis. The rotation axis is parallel to a predetermined direction.

[0008] For example, the pull-out component includes a first hook and a second hook, the rotating ring is U-shaped, the first hook and the second hook are respectively disposed on both sides of the opening of the rotating ring, and the first hook and the second hook are connected to the rotating ring through an adjusting component.

[0009] For example, the adjusting component includes an adjusting screw that passes through a first hook, a second hook, and a rotating ring, and the size of the opening is adjusted by turning the adjusting screw.

[0010] For example, the pull member and the rotating ring are detachably connected.

[0011] For example, the support rod is provided with a screw hole, and the moving rod passes through the screw hole and is threadedly connected to the support rod.

[0012] For example, the first leg includes a first connecting block and a first abutting block. The first connecting block is connected to a support rod, and the first abutting block is connected to the end of the first connecting block away from the support rod. A first supporting end is formed on the side of the first abutting block opposite to the first connecting block, and the first supporting end is planar.

[0013] For example, the second leg includes a second abutment block connected to a support rod. A second support end is formed on the side of the second abutment block opposite to the support rod. The second support end is planar and is spaced apart from the first support end in a predetermined direction.

[0014] For example, a first limiting member is provided on the side of the first abutting block near the second abutting block, the first limiting member extending along the first abutting block in a direction away from the support rod and protruding from the first abutting block; and / or, a second limiting member is provided on the side of the second abutting block near the first abutting block, the second limiting member extending along the second abutting block in a direction away from the support rod and protruding from the second abutting block.

[0021] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0022] This embodiment of the invention provides a disassembly fixture. The disassembly fixture can be used to disassemble IGBT modules. (See reference...) Figure 1The disassembly fixture 10 includes a support assembly 110, a movable component 120, and a pulling component 130. The support assembly 110 includes a first leg 1110, a second leg 1120, and a support rod 1130, with the support rod 1130 connected between the first leg 1110 and the second leg 1120. The first leg 1110 and the second leg 1120 can both be located on the same side of the support rod 1130. The end of the first leg 1110 away from the support rod 1130 forms a first support end for abutting against an external cabinet, and the end of the second leg 1120 away from the support rod 1130 forms a second support end for abutting against an external cabinet. During the disassembly process, the first leg 1110 and the second leg 1120 abut against the external cabinet, providing support force for pulling the component to be disassembled outwards. The movable component 120 is connected to the support rod 1130 and is movable relative to the support rod 1130 in a predetermined direction. The pull-out component 130 is connected to the moving component 120. A limiting space is formed within the pull-out component 130 to restrict the component to be removed. An opening is formed on the pull-out component 130 for the component to pass through, and the opening communicates with the limiting space. That is, the component to be removed enters the limiting space through the opening and is confined within it. For example, the direction of the pull-out component 130 can be adjusted so that the component to be removed can enter the limiting space through the opening.

[0023] Taking the IGBT module as an example, during disassembly, the IGBT module is first placed into the limiting space through the port. The pull-out component 130 located in the limiting space forms a movable whole with the IGBT module. The moving component 120 is operated to make the pull-out component 130 and the IGBT module move together in a predetermined direction away from the cabinet. Since the first support end and the second support end are always pressed against the external cabinet, the support component 110 can provide stable support during the disassembly process, ensuring the smooth movement of the pull-out component 130 and the IGBT module. As the moving component 120 continues to move, the pull-out component 130 will gradually pull the IGBT module out of the external cabinet, thus completing the initial disassembly of the IGBT module. After that, the disassembly fixture 10 can be removed to completely take out the IGBT module.

[0024] The disassembly fixture 10 provided in this application has a support component 110 that abuts against the external cabinet, providing stable support for the disassembly process and reducing the operational difficulty. The cooperation between the moving component 120 and the pulling component 130 enables the disassembly of the component to be disassembled through relatively smooth mechanical pulling, making the process smoother. When the disassembly fixture 10 is applied to the disassembly of IGBT modules, the support component 110 abuts against the external cabinet, forming support in narrow working spaces and providing a reliable force base for the pulling process. This eliminates the need for operators to manually exert force to maintain balance during the pulling action. Combined with the smooth mechanical pulling of the moving component 120 and the pulling component 130, the disassembly of IGBT modules can be achieved even in scenarios with limited space, reducing the operational difficulty caused by space constraints, making the disassembly process simpler and more efficient.

[0025] For example, refer to Figure 1 The movable component 120 may include a movable rod 1220 and a rotating component 1210. The movable rod 1220 is movably connected to the support rod 1130. The rotating component 1210 is connected between the movable rod 1220 and the pull-out component 130, and the pull-out component 130 is rotatable relative to the movable rod 1220 under the drive of the rotating component 1210. The rotating component 1210 can drive the pull-out component 130, which is rotatable relative to both the movable rod 1220 and the support assembly 110. By rotating the pull-out component 130, the direction of the opening can be flexibly adjusted, allowing for better adjustment of the relative position between the opening and the component to be removed, enabling the component to pass through the opening more easily. With this configuration, by rotating the pull-out component 130, the component to be removed can better pass through the opening and enter the limiting space. In the embodiment where the moving rod 1220 and the support rod 1130 are threadedly connected, the moving rod 1220 rotates, and the rotating part 1210 rotates relative to the moving rod 1220, which can counteract the influence of the rotation of the moving rod 1220 on the pulling part 130, thus ensuring the smoothness and success of the pulling process.

[0026] For example, refer to Figure 1The rotating component 1210 may include a fixed ring 1211 and a rotating ring 1212 connected to the pulling component 130. The fixed ring 1211 can be connected to the moving rod 1220. The rotating ring 1212 is connected to the fixed ring 1211 and can rotate relative to the fixed ring 1211 along a rotation axis. The rotation axis can be parallel to a predetermined direction. It is understood that during the pulling process of the component to be removed, if the rotation axis is not parallel to the predetermined direction, the rotation of the rotating ring 1212 may generate a component force, causing the pulling component 130 to wobble or deviate, affecting the accuracy and stability of the pulling. The parallel setting of the rotation axis to the predetermined direction allows the rotation of the rotating ring 1212 to occur only around the rotation axis, reducing unnecessary force interference. The fixed ring 1211 and the moving rod 1220 are firmly connected, ensuring stable force transmission. The rotating ring 1212 can rotate relative to both the fixed ring 1211 and the moving rod 1220, allowing adjustment of the relative angle between the pulling component 130 and the component to be removed, resulting in a simpler and more reasonable structural design.

[0027] For example, refer to Figure 1 The pull-out component 130 and the rotating ring 1212 can be detachably connected. This detachable connection allows the pull-out component 130 to be individually fitted over the component to be removed, ensuring precise alignment between its limiting space and the component, before finally connecting and securing it to the rotating ring 1212. This design avoids difficulties in fitting the component due to the overall structural limitations of the disassembly fixture 10, further reducing the operational difficulty of the disassembly process and improving its flexibility and efficiency.

[0028] For example, refer to Figure 1The pull-out component 130 may include a first hook 1310 and a second hook 1320. The rotating ring 1212 may be U-shaped. The first hook 1310 and the second hook 1320 may be respectively disposed on both sides of the opening of the rotating ring 1212. The first hook 1310 and the second hook 1320 may be connected to the rotating ring 1212 through an adjusting component. The adjusting component can flexibly adjust the distance between the first hook 1310 and the second hook 1320 to accommodate different sizes of components to be removed. Furthermore, by adjusting the distance between the first hook 1310 and the second hook 1320, the opening size can be enlarged before the component to be removed enters, allowing components of different specifications to pass through smoothly, improving adaptability. After the component to be removed enters the limiting space, the opening size can be reduced to prevent the component to be removed from the opening, forming a secure limiting. In this way, the adjusting component adjusts the opening size to ensure smooth entry of the part to be removed and to ensure the limiting space effectively restricts the part to be removed, making the removal operation more stable and controllable. The adjusting component can be any device capable of adjusting the distance between the first hook 1310 and the second hook 1320, including but not limited to the adjusting screw 1230, adjusting buckle, etc. The limiting space is formed between the first hook 1310 and the second hook 1320. Specifically, both the first hook 1310 and the second hook 1320 can have a U-shaped structure with opposite openings.

[0029] For example, refer to Figure 1 The adjusting component may include an adjusting screw 1230, which passes through the first hook 1310, the second hook 1320, and the rotating ring 1212. The size of the opening can be adjusted by turning the adjusting screw 1230. Specifically, the rotating ring 1212 may have threads on the portions corresponding to the two sides of the U-shaped opening, and the adjusting screw 1230 passes through these threads. Thus, by adjusting the distance between the first hook 1310 and the second hook 1320 by turning the screw, the size of the opening can be adjusted, making the operation simple and efficient.

[0030] For example, refer to Figure 1 The support rod 1130 may have a threaded hole, through which the moving rod 1220 passes and is threadedly connected to the support rod 1130. The moving rod 1220 can be a lead screw. The end of the moving rod 1220 away from the pulling part 130 can be a hexagonal nut. In this way, the moving rod 1220 can be controlled by turning it to control the distance and speed of its movement in a predetermined direction, thereby pulling out the part to be removed. The process is more stable and controllable, avoiding impact damage caused by manual forceful pulling. The threaded drive can convert rotational force into pulling force, saving physical strength while improving operational accuracy, making the removal process safer and more efficient.

[0031] For example, refer to Figure 1The first support leg 1110 may include a first connecting block 1111 and a first abutting block 1112. The first connecting block 1111 is connected to the support rod 1130, and the first abutting block 1112 is connected to the end of the first connecting block 1111 away from the support rod 1130. A first support end is formed on the side of the first abutting block 1112 opposite to the first connecting block 1111, and the first support end is planar. The first connecting block 1111 can better ensure the stable connection between the first abutting block 1112 and the support rod 1130. When the planar first support end contacts the external cabinet, it can increase the contact area, distribute the force, and avoid damage to the cabinet surface due to excessive local pressure. The planar contact can improve the stability of the support, prevent the first support leg 1110 from slipping or shifting during disassembly, and ensure that the support assembly 110 provides a continuous and reliable reaction force for the pulling operation.

[0032] For example, refer to Figure 1 The second support leg 1120 includes a second abutment block connected to the support rod 1130. A second support end is formed on the side of the second abutment block opposite to the support rod 1130. The second support end is planar and spaced apart from the first support end in a predetermined direction. The planar second support end increases the contact area when in contact with the external cabinet, distributing the force and preventing damage to the cabinet surface due to excessive local pressure. The planar contact improves the stability of the support, preventing slippage and displacement of the second support leg 1120 during disassembly, and ensuring that the support assembly 110 provides a continuous and reliable reaction force for the pulling operation. The spaced distance between the first and second support ends in the predetermined direction allows for better adaptation to the external cabinet, ensuring the stability of the support.

[0033] For example, refer to Figure 1 A first limiting member 1140 may be provided on the side of the first abutment block 1112 near the second abutment block. The first limiting member 1140 extends along the first abutment block 1112 in a direction away from the support rod 1130 and protrudes from the first abutment block 1112. And / or, a second limiting member 1150 may be provided on the side of the second abutment block near the first abutment block 1112. The second limiting member 1150 extends along the second abutment block in a direction away from the support rod 1130 and protrudes from the second abutment block. Exemplarily, the first limiting member 1140 may be cylindrical and extend in a predetermined direction. The second limiting member 1150 may be cylindrical and extend in a predetermined direction. The first limiting member 1140 and / or the second limiting member 1150 can be inserted into the gap between the external cabinet and the part to be removed, thereby laterally restricting the displacement of the support assembly 110, further enhancing the support stability of the support assembly 110, and improving the stability of the removal process.
