Description

Technical Field

[0001] This disclosure pertains to the field of wind power generation technology, and particularly relates to an auxiliary tooling for the assembly and disassembly of power modules. Background Technology

[0002] Wind power generation, as a green energy source, has attracted much attention from society. In a wind turbine generator set, the power module is mainly responsible for converting the alternating current generated by the wind turbine generator set into electrical energy suitable for the grid requirements, so as to ensure that appropriate power output is provided under different wind speeds.

[0003] Currently, power modules are typically housed within cabinets. Due to the limited internal space of these cabinets, and the numerous components usually housed within the wind turbine tower, the operational space for moving the power modules in and out of the cabinet is also limited. This makes it difficult for operators to grip the power modules, resulting in low efficiency in these operations and consequently impacting the overall assembly and disassembly efficiency. Therefore, providing an auxiliary tooling solution to improve the efficiency of power module assembly and disassembly is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The main objective of this disclosure is to provide an auxiliary tooling that can be installed on a power module, thereby improving the efficiency of power module assembly and disassembly.

[0005] To achieve the above objectives, this disclosure provides the following technical solution:

[0006] In one aspect, this disclosure provides an auxiliary tooling suitable for the assembly and disassembly of a power module. The power module includes a module body and guide rails disposed on both sides of the module body in the width direction. The auxiliary tooling includes a main frame and a limiting member. A limiting groove is formed on the main frame, and the guide rails can be disposed in the limiting grooves, thereby enabling the auxiliary tooling to be installed onto the power module. The limiting member is movably connected to the main frame between a released position and an engaged position. When the guide rail is located in the limiting groove and the limiting member is in the engaged position, the limiting member can limit the guide rails to prevent them from falling out of the limiting grooves.

[0007] In an exemplary embodiment of this disclosure, the main frame includes two spaced-apart holding units and a first connecting portion connected between the two holding units. The limiting member includes two spaced-apart locking units and a second connecting portion connected between the two locking units. Each locking unit is rotatably connected to the holding unit. The limiting groove is formed on the holding unit. The guide rail can be limited within the limiting groove by the cooperation of the locking unit and the holding unit.

[0008] Specifically, the first connecting part serves as the operating handle, or the operating handle is connected to the first connecting part.

[0009] Optionally, the holding unit includes a main frame arm and a first limiting part. The first connecting part is connected to a first end of the main frame arm, and the first limiting part is disposed at a second end of the main frame arm. The locking unit includes a locking body.

When the guide rail is located in the limiting groove and the limiting member is in the engaged position, the second end of the locking body can cooperate with the first limiting part to limit the corresponding sides of the guide rail.

[0010] Specifically, the second end of the locking body can cooperate with the first limiting part to limit it to opposite sides of the guide rail in the first direction. The holding unit also includes a second limiting part, which is connected to the main frame arm and is spaced apart from the first limiting part along the extension direction of the main frame arm. The first limiting part, the main frame arm, and the second limiting part together form the limiting groove. The locking unit also includes a locking part, which protrudes from the second end of the locking body. When the limiting member is in the locking position, the locking part and the second limiting part cooperate to limit it to opposite sides of the guide rail in the second direction, which is perpendicular to the first direction.

When the guide rail is located in the limiting groove, the second limiting part and the main frame arm are respectively located on both sides of the guide rail.

[0012] Specifically, the first limiting part has a limiting surface for limiting the guide rail, and the holding unit further includes a positioning pin, which protrudes from the limiting surface. The guide rail is provided with a positioning hole that matches the positioning pin. When the limiting part is in the engaged position, the positioning pin is detachably inserted into the positioning hole.

[0013] Furthermore, the distance between the free end of the positioning pin and the connecting beam is not less than the length of the guide rail in the extension direction, and a notch is provided in the area of ​​the main frame arm facing the second limiting part.

[0014] According to another exemplary embodiment of this disclosure, the positioning pin is used to connect to a first end in the extension direction of the guide rail, the positioning hole is recessed from the end face of the first end of the guide rail, the second limiting portion and the engaging portion cooperate to limit the second end in the extension direction of the guide rail, and the first end and the second end are disposed opposite to each other.

[0015] Optionally, the auxiliary tooling further includes a flip handle, which is connected to the second connecting part.

[0016] Specifically, the auxiliary tooling further includes a third connecting part, which is connected between the two holding units and spaced apart from the first connecting part. The auxiliary tooling also includes a locking member, which allows the third connecting part to be detachably connected to the second connecting part when the limiting member is in the engaged position.

[0017] Furthermore, the locking member includes a locking pin, and the second connecting part and the third connecting part are respectively provided with connecting holes that match the locking pin. When the limiting member is in the engaged position, the second connecting part and the third connecting part are connected together by placing the locking pin in the connecting hole.

[0018] According to another exemplary embodiment of this disclosure, the auxiliary tooling further includes a boom unit rotatably connected to the main frame and capable of being connected to an external lifting device; and / or, when the limiting member is in the release position, the guide rail can enter the limiting groove or disengage from the limiting groove.

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of this disclosure are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0039] This disclosure provides an auxiliary tooling that can be used to assist in the disassembly and assembly of power modules. For example, but not limited to, the auxiliary tooling can be installed on the power module to assist in the push-pull operation of the power module, thereby facilitating the entry and exit of the power module from the cabinet and improving the disassembly and assembly efficiency of the power module.

[0040] According to an exemplary embodiment of the present disclosure, the power module can be a rail-mounted power module, which may include a module body 50 and rails 51 disposed on both sides of the module body 50 in the width direction, but is not limited thereto.

[0041] Specifically, refer to Figure 2In this embodiment, the power module is roughly hexahedral in shape. The length direction of the power module can be defined as the direction indicated by the letter L, the width direction of the power module can be defined as the direction indicated by the letter W, and the height direction of the power module can be defined as the direction indicated by the letter H. The example given is that the extension direction of the guide rail 51 is parallel to the length direction L of the power module, but this is not a limitation.

[0042] The power modules can be placed inside a cabinet (not shown in the figure). For example, but not limited to, the cabinet can have multiple mounting cavities, and the multiple power modules can be placed in different mounting cavities. In order to stably support the power modules, guide supports that match the guide rail 51 can be provided on the two opposite side walls of the mounting cavity. The guide rail 51 can be placed on the guide supports to support the power modules through the two guide supports.

[0043] As an example, the guide support may include a guide rod or guide groove extending generally in a horizontal direction, as long as it can cooperate with the guide rail 51 and support the power module, it is within the protection scope of this disclosure. As an example, the power module can be placed horizontally in the mounting cavity, for example, but not limited to, when the power module is placed in the mounting cavity, the length direction L of the power module can be set along the front-back direction of the cabinet mounting cavity, but is not limited thereto.

[0044] Specifically, in this embodiment, the power module can be in a horizontal orientation (e.g. Figure 4 The example shown is of putting something into or taking something out of the closet, but it is not the only one. Correspondingly, Figure 2 The medium power module is in a standing position. The auxiliary tooling can be installed on the power module in this standing position, but it is not limited to this.

[0045] Reference Figure 4 The diagram shows an auxiliary fixture mounted on the power module. The operator can manipulate the power module using this fixture, which provides a gripping space for operation. For example, but not limited to, the operator can pull the auxiliary fixture horizontally outward relative to the cabinet, thereby pulling the power module out of the cabinet and achieving a horizontal removal operation. Alternatively, the operator can push the auxiliary fixture horizontally in the opposite direction to push the power module into the mounting cavity of the cabinet, thus achieving a cabinet insertion operation, but this is not a limitation.

[0046] Reference Figures 1 to 4An exemplary embodiment of this disclosure provides an auxiliary tooling that may include a main frame 20 and a limiting member 30. The main frame 20 may form a limiting groove, and the guide rail 51 of the power module may be disposed in the limiting groove. The limiting member 30 is movably connected to the main frame 20 so as to move relative to the main frame 20 between a released position and a locked position. When the guide rail 51 is disposed in the limiting groove and the limiting member 30 is in the locked position, the limiting member 30 can limit the guide rail 51 in the limiting groove of the main frame 20 to prevent the guide rail 51 from falling out of the limiting groove, thereby enabling the auxiliary tooling to be reliably installed on the power module.

[0047] The auxiliary tooling provided in this disclosure includes a main frame 20 and a limiting member 30 movably connected to the main frame 20. When the limiting member 30 is in the engaged position, it can limit the guide rail 51 in the limiting groove of the main frame 20, thereby enabling the auxiliary tooling to be reliably installed on the power module. Operators can operate the power module by operating the auxiliary tooling, which improves the convenience of power module operation and thus improves the efficiency of power module assembly and disassembly.

[0048] Referring again to the accompanying drawings, in this embodiment, the limiting member 30 is rotatably connected to the main frame 20. The main frame 20 includes a holding unit 26, and a limiting groove is disposed on the holding unit 26. The limiting member 30 includes a locking unit 33, which is rotatably connected to the holding unit 26. When the limiting member 30 is in the engaged position, the locking unit 33 and the holding unit 26 cooperate to form an engaged assembly and can limit the guide rail 51 in the limiting groove, but this is not a limitation.

[0049] In this embodiment, the locking unit 33 is rotatably connected to the holding unit 26. In the initial state, the limiting member 30 can be in the released position (e.g., Figure 2 As shown), rotate a certain angle relative to the limiting groove to move away from the limiting groove. At this time, the guide rail 51 can enter the limiting groove of the holding unit 26, and then rotate the limiting member 30 towards the direction closer to the limiting groove to the engaging position (as shown). Figure 3 As shown in the diagram, at this time, the locking unit 33 and the holding unit 26 cooperate to limit the guide rail 51 within the limiting groove, thereby ensuring that the auxiliary tooling is reliably connected to the power module, but this is not a limitation. When it is necessary to remove the auxiliary tooling from the power module, the above components can be operated in reverse.

[0050] This embodiment uses the example of the locking unit 33 rotating counterclockwise from the release position to the engagement position, but it is not limited to this. It can be understood that the rotation direction of the locking unit 33 relative to the holding unit 26 can be set according to actual needs.

[0051] Reference Figure 2When the limiting member 30 is in the release position, the guide rail 51 can enter the limiting groove of the holding unit 26 or disengage from the limiting groove of the holding unit 26, thereby facilitating the installation of the power module onto or removal from the auxiliary fixture, but not limited thereto.

[0052] Reference Figure 3 The drive locking unit 33 rotates relative to the holding unit 26. When the limiting member 30 is in the engaged position, the guide rail 51 can be limited in the limiting groove of the holding unit 26, so that the auxiliary tooling can be reliably connected to the power module. The power module can be operated by operating the auxiliary tooling, but not limited thereto.

[0053] This embodiment is illustrated by taking the limiting member 30 as being rotatably connected to the main frame 20 as an example, but it is not limited thereto. As needed, the limiting member 30 can also be configured to be slidably connected to the main frame 20, all of which are within the protection scope of this disclosure.

[0054] To prevent the power module from flipping due to uneven force on both sides during operation, the auxiliary fixture can be configured to connect to the two guide rails 51. The auxiliary fixture may include two sets of engaging components to engage with the two guide rails 51 respectively.

[0055] Specifically, the main frame 20 may include two clamping units 26 spaced apart and a first connecting part 25 connected between the two clamping units 26. The distance between the two clamping units 26 and the distance between the two guide rails 51 may be the same to meet the requirement that the two clamping units 26 are simultaneously engaged with the two guide rails 51.

[0056] As an example, the two ends of the first connecting part 25 can be fixedly connected to the two holding units 26 to prevent relative movement between the two holding units 26. The two holding units 26 can move synchronously relative to the power module so that the two guide rails 51 are simultaneously positioned in the two limiting slots, or the two guide rails 51 are simultaneously removed from the two limiting slots, thereby improving the reliability of the auxiliary tooling, but this is not a limitation. Alternatively, the two ends of the first connecting part 25 can be connected to the two holding units 26 by fasteners or welding, but this is not a limitation.

[0057] Referring again to the accompanying drawings, the first connecting portion 25 can be connected to the first end of the holding unit 26, but is not limited thereto. The first connecting portion 25 can be used as an operating handle for easy gripping by the operator, but is not limited thereto; the operating handle can be connected to the first connecting portion 25. The operator can operate the auxiliary tooling by operating the first connecting portion 25, thereby operating the power module, improving the ease of use of the auxiliary tooling.

[0058] Further, the first connecting portion 25 is disposed at the first end of the clamping unit 26. When the auxiliary tooling is installed on the power module, the first connecting portion 25 is spaced from the power module to form a gripping space between the power module and the first connecting portion 25, facilitating an operator to grip the first connecting portion 25, but not limited thereto.

[0059] As an example, the first connecting portion 25 and the two clamping units 26 are fixedly connected, such that the main frame 20 is generally formed into a U-shaped frame structure, and the two clamping units 26 are formed into two opposite arms of the U-shaped frame structure, so as to be connectable to the guide rail 51 of the power module, but not limited thereto.

[0060] Correspondingly, the limiting member 30 may include two locking units 33 disposed at intervals and a second connecting portion 34 connected between the two locking units 33. Each locking unit 33 is rotatably connected to the clamping unit 26 such that the locking unit 33 and the clamping unit 26 cooperate to form a clamping assembly.

[0061] In this embodiment, the two locking units 33 are fixed together by the second connecting portion 34, such that the two locking units 33 can move synchronously relative to the guide rail 51 to be able to limit the two guide rails 51 simultaneously, thereby improving the use reliability of the auxiliary tooling. As an example, the second connecting portion 34 is fixed to the locking unit 33 by a welding process or a fastener connection method, but not limited thereto. In this embodiment, the second connecting portion 34 and the two locking units 33 are fixedly connected and formed into a "C" - shaped structure, and the two locking units 33 are formed into two arms of the "C" - shaped structure, so as to be connectable to the guide rail 51 of the power module, but not limited thereto.

[0062] In this embodiment, the second connecting portion 34 is rotatably connected between the two clamping units 26. The second connecting portion 34 serves as the rotating shaft of the limiting member 30, such that the limiting member 30 can rotate relative to the main frame 20 around the second connecting portion 34, but not limited thereto. As an example, the second connecting portion 34 and the first connecting portion 25 are disposed at intervals, and a space between the second connecting portion 34 and the first connecting portion 25 can be formed into an operation space for gripping the first connecting portion 25 or for flipping the second connecting portion 34, but not limited thereto.

[0063] Further, to improve the use convenience of the auxiliary tooling, the auxiliary tooling further includes a flipping handle 35, and the flipping handle 35 is connected to the second connecting portion 34. An operator can rotate the limiting member 30 by gripping the flipping handle 35, but not limited thereto.

[0064] Referring again to the accompanying drawings, the holding unit 26 may include a main frame arm 22 and a first limiting part 21 connected to the main frame arm 22. The first connecting part 25 may be connected to the first end of the main frame arm 22, and the first limiting part 21 may be disposed at the second end of the main frame arm 22.

[0065] In this embodiment, the main boom 22 may include a first boom section and a second boom section arranged at an angle. A second connecting portion 34 is disposed at the connection between the first boom section and the second boom section. The first end of the first boom section is the first end of the main boom 22, and the first connecting portion 25 is fixed to the first end of the first boom section. The first end of the second boom section is the second end of the main boom 22, and the first limiting portion 21 is fixed to the first end of the second boom section, but this is not a limitation. As an example, the included angle α between the first boom section and the second boom section satisfies 120°≤α≤150°. This disclosure facilitates the operation of the first connecting portion 25 and improves the ease of use of the auxiliary tooling by arranging the first boom section and the second boom section at an angle, but this is not a limitation.

[0066] Correspondingly, the locking unit 33 may include a locking body 36. The first end of the locking body 36 is rotatably connected to the main frame arm 22. When the guide rail 51 is located in the limiting groove and the limiting member 30 is in the engaged position, the second end of the locking body 36 can cooperate with the first limiting part 21 to limit the opposite sides of the guide rail 51. The first end and the second end of the locking body 36 are arranged opposite to each other.

[0067] In this embodiment, for ease of description, the example is taken where the second end of the locking body 36 cooperates with the first limiting part 21 to limit both sides of the guide rail 51 in the extension direction, but this is not a limitation. Depending on the needs, the second end of the locking body 36 and the first limiting part 21 may cooperate to limit both sides of the guide rail 51 in the height direction. In this embodiment, the height direction of the guide rail 51 may be parallel to the height direction H of the power module, but this is not a limitation.

[0068] In this embodiment, the first limiting part 21 may have a limiting surface for limiting the guide rail 51. When the limiting member 30 is in the engaged position, the end face of the second end of the locking body 36 may be arranged parallel to the limiting surface of the first limiting part 21 so as to limit the two opposite sides of the guide rail 51, but not limited thereto.

[0069] In this embodiment, when the limiting member 30 is in the engaged position, the limiting surface of the first limiting part 21 is in contact with the first end face of the guide rail 51 extending in the direction of extension, and the end face of the second end of the locking body 36 is in contact with the second end face of the guide rail 51 extending in the direction of extension, thereby limiting both sides of the guide rail 51 extending in the direction of extension.

[0070] Referring again to the accompanying drawings, in the above embodiment, the example given is that the first limiting part 21 and the second end of the locking body 36 are mutually limiting each other on both sides of the extending direction of the guide rail 51. To improve the connection reliability between the auxiliary tooling and the power module, the auxiliary tooling can also limit the height of the guide rail 51 on both sides.

[0071] Specifically, the holding unit 26 may further include a second limiting part 23, which is connected to the main frame arm 22. The second limiting part 23 is spaced apart from the first limiting part 21 along the extension direction of the main frame arm 22 and spaced apart from the main frame arm 22 at a predetermined distance in the extension direction perpendicular to the main frame arm 22. A connecting beam 28 is provided between the second limiting part 23 and the main frame arm 22, so that the second limiting part 23 can be fixed to the main frame arm 22 by the connecting beam 28. Thus, a limiting groove is formed between the first limiting part 21, the main frame arm 22, the connecting beam 28 and the second limiting part 23.

[0072] As an example, the first limiting part 21, the second arm part of the main arm 22, the connecting beam 28, and the second limiting part 23 are formed into a limiting groove with a "⺋" structure so as to surround the periphery of the guide rail 51. As an example, the extending direction of the first limiting part 21 is perpendicular to the extending direction of the main arm 22, and the first limiting part 21 and the connecting beam 28 are spaced apart and arranged approximately parallel, but this is not a limitation.

[0073] In this embodiment, when the guide rail 51 is located within the limiting groove, the second limiting part 23 and the main frame arm 22 are located on opposite sides of the guide rail 51 in the height direction, but this is not a limitation. As an example, the second limiting part 23 and the main frame arm 22 extend in roughly the same direction, but this is not a limitation.

[0074] Corresponding to the second limiting part 23, the locking unit 33 may also include an engaging part 32. The engaging part 32 extends protruding from the second end of the locking body 36. When the limiting member 30 is in the engaging position, the engaging part 32 cooperates with the second limiting part 23 to limit the two sides opposite to each other in the height direction of the guide rail 51, but is not limited thereto.

[0075] The auxiliary tooling provided in this embodiment includes a first limiting part 21 for limiting the guide rail 51 on opposite sides in the first direction and a second end of the locking body 36, and also includes a second limiting part 23 for limiting the guide rail 51 on opposite sides in the second direction and a locking part 32, as shown in the reference. Figure 3 When the limiting member 30 is in the engaged position, the auxiliary tooling can limit all four sides of the guide rail 51 in the circumferential direction, so that the guide rail 51 is reliably limited in the limiting groove of the main frame 20, thereby enabling the auxiliary tooling to be reliably installed on the power module, but not limited thereto.

[0076] As an example, the second limiting part 23 is spaced apart from the first limiting part 21 and is formed approximately in the middle of the main frame arm 22 along the extension direction of the main frame arm 22, so that the limiting groove is located between the second limiting part 23 and the first limiting part 21.

[0077] As an example, the locking body 36 is generally formed as a long strip plate, and the engaging part 32 extends from the second end of the locking body 36 in a direction away from the first end, so that the second end of the locking body 36 and the engaging part 32 generally enclose to form an L-shaped structure. When the limiting member 30 is in the engaging position, the L-shaped structure can limit the two adjacent sides of the guide rail 51, but not be limited thereto.

[0078] Continue to refer to Figure 4 The guide rail 51 has a support surface for engaging with the guide support. When the auxiliary tooling is installed on the power module, the support surface is located on the side facing away from the main frame arm 22. When the power module is pushed into the mounting cavity in the horizontal direction, the support surface can be located on the lower surface of the guide rail 51 to fit against the guide support. The second limiting part 23 and the first limiting part 21 are spaced apart along the extension direction of the main frame arm 22 to form a groove for limiting. The guide rail 51 can enter and exit the limiting groove through this groove, but is not limited thereto.

[0079] This embodiment uses the example of the engaging part 32 being located on the side of the guide rail 51 opposite to the supporting surface, and the second limiting part 23 being located on the side of the guide rail 51 where the supporting surface is located, but this is not a limitation. The second limiting part 23 can be located on the side of the guide rail 51 opposite to the supporting surface as needed. In this case, the second limiting part 23 can be directly fixed to the main frame arm 22, and the corresponding engaging part 32 is located on the side of the guide rail 51 where the supporting surface is located. At this time, the locking unit 33 can rotate clockwise from the released position to the engaged position, but this is not a limitation.

[0080] In this embodiment, two locking units 33 are rotatably connected to the corresponding holding units 26, and each locking unit 33 cooperates with its corresponding holding unit 26 to form a locking assembly.

[0081] To further improve the connection reliability between the auxiliary tooling and the guide rail 51, a positioning hole (not shown) is provided at the first end of the guide rail 51. As an example, the positioning hole is recessed inward from the end face extending in the direction of the guide rail 51, but this is not a limitation.

[0082] return Figure 1The holding unit 26 may also include a positioning pin 24 that matches the positioning hole. The positioning pin 24 is disposed on the first limiting part 21. For example, but not limited to, the positioning pin 24 protrudes from the limiting surface of the first limiting part 21. When the limiting member 30 is in the engaged position, the positioning pin 24 is detachably inserted into the positioning hole. In this way, by inserting the positioning pin 24 into the positioning hole, the guide rail 51 is reliably connected to the auxiliary tooling, preventing the power module from accidentally detaching from the auxiliary tooling, thereby improving the reliability of the auxiliary tooling. As an example, the positioning pin 24 extends perpendicular to the limiting surface, but is not limited thereto. As needed, the angle between the extension direction of the positioning pin 24 and the limiting surface can be in the range of 75° to 105°, as long as it can be inserted and matched with the positioning hole, but is not limited thereto.

[0083] In this embodiment, the positioning pin 24 can be installed at the first end of the guide rail 51 in the extension direction, the locking unit 33 rotates relative to the clamping unit 26, and the second limiting part 23 and the engaging part 32 are arranged facing each other to form a clamping structure and are installed at the second end of the guide rail 51 in the extension direction, thereby further improving the connection reliability of the auxiliary tooling and the power module.

[0084] In this embodiment, the distance between the free ends of the connecting beam 28 and the positioning pin 24 is not less than the length of the guide rail 51 in the extension direction. The area of ​​the main frame arm 22 facing the second limiting part 23 is provided with a notch 29 to form an operating space between the second limiting part 23 and the main frame arm 22, so that the second end of the guide rail 51 can enter the limiting groove first, and the first end of the guide rail 51 can avoid the positioning pin 24 and enter the limiting groove. Then, the auxiliary tooling can be moved relative to the power module along the extension direction of the positioning pin 24 and the positioning pin 24 can be inserted into the positioning hole. At this time, the second limiting part 23 is kept limited at the second end of the guide rail 51 in the extension direction. Then, the limiting member 30 can be flipped to limit the guide rail 51 and prevent the guide rail 51 from moving relative to the limiting groove, thus preventing the guide rail 51 from falling out of the limiting groove.

[0085] Furthermore, the positioning pin 24 and the second limiting part 23 should each have sufficient structural strength to prevent the positioning pin 24 or the second limiting part 23 from being stretched and deformed or even damaged due to the excessive weight of the power module during the power module flipping or horizontal pushing and pulling process, thereby improving the reliability of the auxiliary tooling.

[0086] To further improve the reliability of the auxiliary tooling, the auxiliary tooling may also include a third connecting part 27. The third connecting part 27 is connected between the two holding units 26 and is spaced apart from the first connecting part 25. The auxiliary tooling may also include a locking member 40. When the limiting member 30 is in the engaged position, the third connecting part 27 is detachably connected to the second connecting part 34 through the locking member 40. This prevents the limiting member 30 from accidentally rotating relative to the main frame 20 during the movement of the auxiliary power module, thus preventing the power module from disengaging from the auxiliary tooling and improving its reliability. In addition, the third connecting part 27 improves the structural strength of the main frame 20.

[0087] In this embodiment, the third connecting portion 27 and the first connecting portion 25 are arranged in parallel, but this is not a limitation. An operating space for the rotation limiting member 30 is formed between the first connecting portion 25 and the third connecting portion 27. As an example, the first connecting portion 25 and the third connecting portion 27 can be beam structures, but this is not a limitation. The third connecting portion 27 can be fixed between the two holding units 26 by welding or fastener connection, but this is not a limitation.

[0088] Referring again to the accompanying drawings, as an example, the locking member 40 may include a locking pin. The second connecting part 34 and the third connecting part 27 are respectively provided with connecting holes that match the locking pin. When the limiting member 30 is in the engaged position, the second connecting part 34 and the third connecting part 27 are connected together by setting the locking pin in the connecting hole. During the movement of the power module, the limiting member 30 is reliably connected to the main frame 20, thereby further improving the reliability of the auxiliary tooling, but this is not a limitation.

[0089] In this embodiment, the third connecting part 27 is connected to the middle part of the main frame arm 22 in the extending direction, and when the limiting member 30 is in the engaged position, the third connecting part 27 can be fitted with the second connecting part 34, but this is not a limitation. As an example, the first connecting part 25, the third connecting part 27, the second limiting part 23, and the first limiting part 21 are arranged sequentially and at intervals from the first end to the second end of the main frame arm 22 in the extending direction, but this is not a limitation.

[0090] This embodiment uses the locking member 40 including the locking pin as an example for illustration, but it is not limited thereto. As needed, the locking member 40 may also include bolts. As long as the locking member 40 can reliably connect the limiting member 30 to the main frame 20, it is within the protection scope of this disclosure.

[0091] To facilitate connection with external lifting devices, the auxiliary tooling also includes a boom unit 10, which is rotatably connected to the main frame 20 and can be connected to external lifting devices. As an example, the boom unit 10 includes a boom 12 and a lug 11, wherein the boom 12 is rotatably connected between two clamping units 26, and the lug 11 is connected to the boom 12, but is not limited thereto.

[0092] In this embodiment, the boom 12 is configured in a U-shape. The open end of the U-shape is rotatably connected to the main frame 20. For example, but not limited to, the U-shape includes opposing two side arms and a connecting arm. The first ends of the two side arms are rotatably connected to the main frame arm 22, for example, but not limited to, rotatably connected between the first limiting part 21 and the second limiting part 23, but not limited thereto. The connecting arm is connected to the second ends of the two side arms, and the lifting lug 11 is provided on the connecting arm, but not limited thereto. The auxiliary tooling provided in this disclosure, by setting the boom unit 10 on the main frame 20, enables the auxiliary tooling to be used in conjunction with an external lifting device to meet the lifting requirements of the power module. For example, but not limited to, the power module can be lifted to a predetermined height by the lifting device, and then the operator can push the power module into the cabinet by horizontal pushing and pulling to realize the cabinet entry operation, or pull it out of the cabinet to realize the cabinet exit operation, but not limited thereto.

[0093] This disclosure utilizes an auxiliary tooling, including a boom unit 10 rotatably connected to the main frame 20, which, in conjunction with an external lifting device, can lift the power module, thereby enabling the power module to move in position, such as, but not limited to, moving the power module at different heights to meet the requirements for loading and unloading the power module; during the lifting process of the auxiliary tooling, the posture of the power module can also be adjusted by manipulating the auxiliary tooling, such as, but not limited to, flipping the power module.

[0094] Furthermore, the auxiliary tooling provided in this disclosure has a simple structure and is easy to operate. During the disassembly and assembly of the power module, it allows for single-person operation, thereby reducing manual intervention in the disassembly and assembly process of the power module and improving the disassembly and assembly efficiency of the power module.

[0095] In this embodiment, the boom unit 10 and the main frame 20 are rotatably connected. During the use of the clamping unit 26, interference between the boom unit 10 and other components can be avoided. For example, but not limited to, when the power module is pushed and pulled horizontally, since the height of the mounting cavity of the cabinet used to accommodate the power module is limited, the boom unit 10 can be rotated to be close to the main frame 20 during the process of the auxiliary tooling and the power module entering the cabinet together, so as to avoid interference between the boom unit 10 and other components of the cabinet, thus making it possible for the auxiliary tooling and the power module to enter and exit the cabinet together.

[0096] In addition, since this auxiliary tooling can be used in conjunction with external lifting devices, it can meet the needs of power modules of different heights for entering and exiting the cabinet.

[0097] Furthermore, the auxiliary tooling provided in this disclosure can be moved in and out of the cabinet together with the power module, which further reduces manual intervention in the power module disassembly and assembly process compared with the traditional operation of manually lifting the power module in and out of the cabinet.

[0098] In summary, the auxiliary fixture provided in this embodiment can be installed on the power module when it is in a standing position. Before entering the cabinet, the power module can be flipped to a horizontal position; for example, but not limited to, the power module can be flipped on the auxiliary fixture to adjust it from a standing to a horizontal position for easier entry and exit from the cabinet. During the process of adjusting the power module from a standing to a horizontal position, the operator can grip the operating handle (first connecting part 25), improving the ease of use of the auxiliary fixture.

[0099] Since the auxiliary tooling includes the boom unit 10, it can be connected to an external lifting device, thereby facilitating the hoisting of the power module and enabling the power module to be raised or lowered.

[0100] Before the auxiliary tooling is installed onto the power module, the boom unit 10 can be connected to the external lifting device.

[0101] The auxiliary fixture can be installed when the power module is in a standing position, such as... Figure 2 As shown. Holding the first connecting part 25, adjust the auxiliary tooling to a vertical position, and adjust the locking unit 33 and the boom unit 10 to the desired position. Figure 2 As shown, adjust the auxiliary tooling to position the two guide rails 51 of the power module respectively within the limiting slots of the two holding units 26. Lift the auxiliary device upwards to insert the positioning pin into the positioning hole of the guide rail 51. Then operate the flip handle 35 to rotate the limiting member 30 relative to the main frame 20 until the second end of the locking body 36 and the engaging part 32 are respectively in contact with the outer circumferential surface of the guide rail 51. At this time, the connecting holes of the second connecting part 34 and the third connecting part 27 are aligned. The second connecting part 34 and the third connecting part 27 are locked by the locking member 40, thus achieving the locking of the limiting member 30 and the main frame 20. Figure 3 As shown.

[0102] After the auxiliary tooling is installed, it can be lifted upwards using a lifting device. During the lifting process, the operator can hold the operating handle to prevent the main frame 20 from rotating relative to the boom unit 10, which would cause the center of gravity of the auxiliary tooling to become unstable, thereby improving the reliability of the auxiliary tooling.

[0103] Before the power module needs to be placed in the cabinet, the angle between the boom unit 10 and the main frame 20 can be continuously adjusted by holding the first connecting part 25, so that the power module is adjusted from a standing position to a horizontal position, such as... Figure 4 As shown.

[0104] After the first connecting part 25 is held and the entire auxiliary device and power module are moved into the cabinet in a horizontal position, the height of the auxiliary device is adjusted so that the guide rail 51 contacts the guide support of the cabinet. The locking part 40 is removed, and the limiting part 30 is rotated so that the limiting part 30 is in the release position. The first connecting part 25 is pushed until the positioning pin disengages from the positioning hole. After the auxiliary device disengages from the guide rail 51 of the power module, the angle of the auxiliary device is adjusted and the auxiliary device is pulled out of the cabinet to complete the installation of the power module into the cabinet.

[0105] The operation of each component is roughly the same for the power module's out-of-cabinet and in-cabinet actions, so it will not be described in detail here.
