Description

Technical Field

[0001] This disclosure pertains to the field of wind power generation technology, and particularly relates to a handling auxiliary tooling. Background Technology

[0002] Wind power generation, as a green energy source, has attracted much attention from society. In wind turbine generator sets, power modules are typically used to control the generator's rotational speed and load to ensure appropriate power output under different wind speeds.

[0003] Power modules are one of the most important components of wind turbine generators, and therefore, they receive considerable attention during manufacturing and maintenance. Taking power module manufacturing as an example, production typically employs assembly line operations, often involving transfers between different production lines. These transfers usually require manual handling of the power modules. Due to their considerable weight, manual handling is not only inefficient but also poses significant safety risks, including damage from drops and injuries to personnel. Utility Model Content

[0004] The main objective of this disclosure is to provide a handling auxiliary fixture to assist in the handling of power modules.

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

[0006] In one aspect, this disclosure provides a handling auxiliary fixture for handling a power module. The handling auxiliary fixture includes a fixture body and two clamping claws. The fixture body has lifting lugs, and at least one of the two clamping claws is a movable clamping claw. The movable clamping claw is movably connected to the fixture body between a release position and a gripping position. When the movable clamping claw is in the gripping position, the two clamping claws can clamp the power module, allowing the handling auxiliary fixture to be installed on the power module.

[0007] According to an exemplary embodiment of the present disclosure, the handling auxiliary tooling further includes a plurality of positioning parts, the plurality of positioning parts being connected to the tooling body, each positioning part being provided with a contact surface for contacting the side wall of the power module, the plurality of positioning parts being spaced apart and surrounding to form a positioning cavity, and two latches being disposed within the positioning cavity.

[0008] Optionally, the mating surface of the positioning part includes a first mating surface and a second mating surface, and the first mating surface and the second mating surface are set at an angle, so that the plurality of positioning parts are used to position the plurality of corners of the mounting surface of the power module.

[0009] Specifically, the first bonding surface and the second bonding surface are arranged perpendicularly.

[0010] According to another exemplary embodiment of this disclosure, the movable claw is movably connected to the tooling body, such that the two claws can approach or move away from each other, and the handling auxiliary tooling includes a guide for guiding the movement of the movable claw, the movable claw being movably connected to the guide.

[0011] Optionally, the handling auxiliary tooling includes a telescopic component for driving the movable claw to move. The telescopic component is connected between the two claws, and the telescopic component drives the two claws to move closer or further apart.

[0012] Specifically, the power module has two plug-in portions that match the claws, and the handling auxiliary tooling also includes a safety locking member. When the two claws are respectively inserted into the corresponding plug-in portions, the safety locking member can limit the claws to the plug-in portions.

[0013] Furthermore, the latch includes a latch body and a latch finger connected to the latch body. The latch finger extends from the latch body in the direction of movement of the movable latch toward the insertion portion. The safety locking member includes an elastic member. When the elastic member and the latch finger are located on the same side of the latch body, the elastic member applies a pulling force to the latch body. Alternatively, when the elastic member and the latch finger are located on opposite sides of the latch body, the elastic member applies a compressive force to the latch body.

[0014] According to another exemplary embodiment of this disclosure, the safety locking member includes a locking pin, which can lock the movable claw in the insertion portion when the claw is in a predetermined position of the insertion portion.

[0015] Optionally, the power module has two plug-in portions that mate with the two latches, each latch including an elastic pad disposed on a contact surface of the latch for contacting the plug-in portion.

[0016] Specifically, the tooling body includes a pair of side beams spaced apart and a cover plate connected between the pair of side beams. The pair of side beams are located outside the two claws. The guide is connected between the pair of side beams. The cover plate covers the outside of the two claws.

[0017] Furthermore, the tooling body also includes a boom, which is disposed above the cover plate, and the end of the boom is provided with a boom seat, and the two boom seats are connected to a pair of side beams.

[0018] According to another exemplary embodiment of this disclosure, the boom seat is provided with a first mounting hole, the side beam is provided with a second mounting hole, one of the first mounting hole and the second mounting hole is a slotted hole, and the boom seat and the side beam are connected together by fasteners; and / or, the lifting lug is provided with a plurality of lifting holes, and the plurality of lifting holes are spaced apart along the extension direction of the boom.

[0019] According to another exemplary embodiment of this disclosure, the handling auxiliary tooling further includes a position indicator for indicating the position of the movable claw, the position indicator being connected to the movable claw and disposed above the cover plate; and / or, the tooling body further includes a gripping handle connected to the cover plate.

[0020] The handling auxiliary tooling provided by this disclosure has at least the following beneficial effects: The movable claws are slidably connected to the tooling body, making the distance between the two claws adjustable. The relative movement of the two claws enables the release and gripping of the power module. When the two claws are gripping the power module, the handling auxiliary tooling can be reliably installed on the power module. At this time, the handling auxiliary tooling can carry the power module and move together, thereby realizing the auxiliary handling of the power module to meet the needs of transferring the power module between different locations.

[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 a handling auxiliary tooling for handling power modules. For example, but not limited to, when power modules need to be transferred between different work lines, the handling auxiliary tooling can assist in the handling of power modules without the need for direct handling by operators, reducing the risk of power modules falling during handling and thus improving the safety of the power module handling process.

[0040] In this embodiment, the power module is provided with a plug-in portion for engaging with the latch 40 described below. As an example, the power module may include a housing (not shown) and a module body (not shown) connected inside the housing, the housing being provided with the plug-in portion (not shown). In this embodiment, the plug-in portion can be formed by a protruding structure formed on the outer surface of the housing. For example, the outer edge of the top wall of the power module housing protrudes outward, forming an outward flange relative to the side wall of the housing, thereby forming the plug-in portion at the lower part of the outward flange. In this embodiment, the housing includes a sheet metal frame structure, but is not limited thereto. In this embodiment, the plug-in portion can be a top flange of the sheet metal structure, but is not limited thereto. The latch 40 described below can be inserted below the flanged structure and engage with the lower surface of the flanged structure.

[0041] Furthermore, the insertion part may also have a separate handle structure on the outer surface of the housing for mates with the handling auxiliary tooling. This handle structure may be formed as an insertion part, but is not limited thereto. As an example, the handle structure may have a handle groove for the insertion of the latch 40, but is not limited thereto.

[0042] Reference Figures 1 to 3 The handling auxiliary tooling may include a tooling body 10 and two claws 40. The tooling body 10 has a lifting lug 11, which can be connected to an external lifting device. With the assistance of the lifting device, the handling auxiliary tooling can be lifted or lowered as needed, thereby transferring its position and enabling the handling and transfer of the power module.

[0043] In order to cooperate with the latch 40, the power module may be provided with at least two plug-in parts. For ease of description, two plug-in parts are provided, and the two plug-in parts are respectively matched with the latch 40.

[0044] To ensure a reliable connection with the power module, at least one of the two latches 40 is a movable latch. This movable latch is movably connected to the fixture body 10 between a release position and a gripping position. When the movable latch is in the gripping position, both latches 40 can be inserted into the two insertion portions, allowing the transport auxiliary fixture to be reliably installed on the power module. This enables the power module and the transport auxiliary fixture to be lifted or lowered together. For example, but not limited to, when the transport auxiliary fixture is installed on the power module, a lifting device can be activated. With the assistance of the lifting device, the transport auxiliary fixture can carry the power module and move together, thus achieving assisted transport of the power module. For example, during the power module manufacturing process, this transport auxiliary fixture can meet the transfer needs of the power module between different production lines, reducing the risk of accidental drops and improving the safety of the power module during transport.

[0045] In the above embodiments, when the movable claw is in the gripping position, the two claws 40 can be inserted into the two plug-in parts respectively, so that the handling auxiliary tooling can be reliably installed on the power module; when the movable claw is in the release position, the two claws 40 can disengage from their respective plug-in parts to prepare for the next connection with the power module.

[0046] The handling auxiliary tooling provided in this disclosure includes two latches 40, and at least one of the two latches 40 is a movable latch. As an example, this embodiment is described with both latches 40 designed as movable latches, but this is not a limitation. As needed, one of the two latches 40 may be a movable latch and the other a fixed latch fixed to the tooling body 10, but this is not a limitation.

[0047] As an example, this embodiment describes the movable claw being slidably connected to the tooling body 10. For example, but not limited to, the movable claw is slidably connected to the tooling body 10 between the release position and the gripping position, so that the two claws 40 can approach or move away from each other, thereby realizing the gripping or release of the power module by the two claws 40.

[0048] Reference Figure 1 For ease of description, two latches 40 are spaced apart on the tooling body 10 along the first direction. In an embodiment where the movable latches are slidable relative to the tooling body 10, the sliding direction of the movable latches is parallel to the first direction, but is not limited thereto. In this embodiment, both latches 40 are movable latches, and the two latches 40 are spaced apart along the length direction L of the transport auxiliary tooling. Each movable latch slides along the length direction L of the transport auxiliary tooling, causing the two latches 40 to move closer or further apart.

[0049] like Figure 1 As shown, the length direction of the handling auxiliary tooling can be the direction indicated by the letter L, the width direction of the handling auxiliary tooling can be the direction indicated by the letter W, and the height direction of the handling auxiliary tooling can be the direction indicated by the letter H. Among them, the length direction L, the width direction W, and the height direction H are set perpendicular to each other, but are not limited to this.

[0050] The above embodiment is illustrated by taking the example of two movable claws sliding along the length direction L of the transport auxiliary tooling, but this is not a limitation. As needed, the movable claws can also be configured to pivotally connect with the tooling body 10 (not shown in the figure). In this case, the extension direction of the pivot axis can be parallel to the width direction W of the transport auxiliary tooling, but this is not a limitation. Furthermore, the movable claws can also be configured to be detachably connected to the tooling body 10, all of which are within the scope of this disclosure.

[0051] Continue to refer to Figure 1 In this embodiment, the latch 40 includes a latch body 41 and latch fingers 49 connected to the latch body 41. The two latch bodies 41 are spaced apart along the length direction L of the transport auxiliary tooling. Each latch body 41 is provided with a latch finger 49. The two latch fingers 49 extend towards each other or away from each other along the length direction L of the transport auxiliary tooling, so that the two latches 40 can be inserted into the above-mentioned insertion part, but not limited thereto.

[0052] The claw body 41 is configured as a plate and is arranged in a generally longitudinal direction. That is, the height direction of the claw body 41 is parallel to the height direction H of the handling auxiliary tooling, and the extension direction of the claw body 41 is generally parallel to the width direction of the handling auxiliary tooling, but not limited thereto.

[0053] As an example, the latch finger 49 is arranged perpendicularly to the latch body 41 and at the bottom end of the latch body 41, so that the cross-section of the latch 40 along the extension direction of the guide member 44 is L-shaped, but this is not a limitation. If needed, the latch finger 49 can also be connected to the top end of the latch body 41, or located in the middle of the latch body 41 along its height direction H. It should be noted that the middle of the latch body 41 along its height direction H can be any position other than the end.

[0054] Reference Figure 1 and Figure 3 This embodiment uses the example of two latching claws 49 extending in opposite directions for illustration, but it is not limited thereto. When the movable latching claw is in the released position, the two latching claws 40 can be located in the space between the two plug-in parts respectively. Then, the two movable latching claws move away from each other so that they can be inserted into their respective plug-in parts, so that the two latching claws 40 are in the gripping position respectively. At this time, the handling auxiliary tooling can be reliably installed on the power module, but it is not limited thereto.

[0055] Furthermore, to prevent the power module from being scratched by friction between the latch 40 and the plug-in portion, the latch 40 in this embodiment may also include an elastic pad 42. The elastic pad 42 is disposed on the contact surface of the latch 40 for contacting the plug-in portion, for example, but not limited to, the elastic pad 42 is disposed on the top surface and / or outer surface of the latch finger 49. As an example, the elastic pad 42 can be an elastic rubber pad, but is not limited thereto.

[0056] In this embodiment, the side of the two latches 40 facing each other can be defined as the inner side of the two latches 40, and the side of the two latches 40 moving away from each other can be defined as the outer side of the two latches 40. It is understood that in this embodiment, the two latch fingers 49 extend away from each other, so the outer surface and top surface of the latch fingers 49 can contact the insertion part, and the elastic pad 42 can be disposed on the outer surface and top surface of the latch fingers 49, but is not limited thereto. In the embodiment where the two latch fingers 49 extend towards each other, the inner surface and top surface of the latch fingers 49 can contact the insertion part. In this embodiment, the elastic pad 42 can be disposed on the inner surface and top surface of the latch fingers 49, but is not limited thereto.

[0057] Continue to refer to Figure 1 To improve the reliability of the movement of the movable jaw, the handling auxiliary tooling may also include a guide 44 for guiding the movement of the movable jaw 40. The guide 44 may extend along the length direction L of the handling auxiliary tooling, and the movable jaw 40 is movably connected to the guide 44 so as to be able to move along the guide 44, but is not limited thereto. As an example, the jaw body 41 may be movably disposed on the guide 44, but is not limited thereto.

[0058] In this embodiment, the guide member 44 can be a guide rod or a guide groove, both of which are within the protection scope of this disclosure.

[0059] As an example, this embodiment uses a tube with a circular cross-section for the guide member 44 as an example for illustration. Alternatively, the guide member 44 can also be a non-circular tube, but this is not a limitation. Depending on the needs, the cross-section of the guide member 44 can be elliptical, rectangular, triangular, etc., all of which are within the scope of this disclosure, but are not limited thereto. Furthermore, a linear bearing 45 can be provided between the latch body 41 and the guide member 44 to reduce frictional damage between the latch body 41 and the guide member 44, thereby improving the service life of the guide member 44, but this is not a limitation.

[0060] This embodiment is illustrated by taking a handling auxiliary tooling that includes two guide members 44. The two guide members 44 are parallel and spaced apart along the width direction W of the handling auxiliary tooling, and each guide member 44 extends along the length direction L of the handling auxiliary tooling, that is, each guide member 44 extends along the moving direction of the movable claw. However, this is not a limitation.

[0061] Continue to refer to Figure 1 In order to drive the movement of the movable claws, in this embodiment, the handling auxiliary tooling may also include a telescopic member 43 for driving the movement of the movable claws. The telescopic member 43 is connected between the two claws 40, and the extension and retraction of the telescopic member 43 drives the two claws 40 to move closer or further apart.

[0062] In this embodiment, the telescopic component 43 can be a telescopic cylinder, a lead screw assembly, or an electric push rod, but is not limited thereto. This embodiment connects two movable claws between one telescopic component 43, allowing both claws to be driven simultaneously. Compared to embodiments where each movable claw has its own independently installed drive component, this embodiment reduces the number of components in the handling auxiliary tooling, thereby simplifying its structure, but is not limited thereto.

[0063] This embodiment uses the telescopic member 43, which includes an electric push rod, as an example. The extension direction of the electric push rod is parallel to the extension direction of the guide member 44, but it is not limited thereto.

[0064] Of course, each movable claw can also be equipped with an independent drive unit as needed. The two drive units can be fixed on the tooling body 10 respectively and can control the movement parameters of the movable claws respectively. For example, but not limited to, the movement start time of the movable claws can be controlled separately, or the movement speed of the movable claws can be controlled separately, or the movement direction of the movable claws can be controlled separately, but not limited to this.

[0065] According to an optional embodiment of this disclosure, in an embodiment where one of the two latches 40 is a fixed latch, the driving member is directly fixed to the tooling body 10, or the driving member can also be connected between the two latches 40. Since the fixed latch is fixedly connected to the tooling body 10, the telescopic member 43 is connected between the movable latch and the fixed latch, so that the telescopic member 43 is indirectly connected to the tooling body 10 through the fixed latch, but this is not a limitation.

[0066] As an example, the telescopic member 43 is spaced apart between the two guide members 44 along the width direction W of the handling auxiliary tooling, and the telescopic direction of the telescopic member 43 is parallel to the extension direction of the guide member 44, but is not limited thereto.

[0067] Continue to refer to Figure 1 and Figure 3 To further improve the reliability of the handling auxiliary tooling, the handling auxiliary tooling may also include a safety locking element 46. When the two claws 40 are inserted into the corresponding plug-in parts, the safety locking element 46 can limit the claws 40 at the plug-in parts, preventing the claws 40 from coming out of the plug-in parts during the handling of the power module using the handling auxiliary tooling, thereby improving the reliability of the handling auxiliary tooling.

[0068] Referring again to the accompanying drawings, this embodiment will be described using the safety locking member 46 including an elastic member as an example. Specifically, when the elastic member and the latch finger 49 are located on the same side of the latch body 41, the elastic member applies a pulling force to the latch body 41; or, when the elastic member and the latch finger 49 are located on opposite sides of the latch body 41 (not shown), the elastic member applies a compressive force to the latch body 41. As an example, the extension direction of the elastic member is generally parallel to the movement direction of the movable latch, but this is not a limitation.

[0069] As an example, the safety locking member 46 and the latching finger 49 may be spaced apart along the height direction of the latching finger body 41 to avoid interference between the latching finger 49 and the safety locking member 46 during the insertion of the latching finger into the connector, but this is not a limitation. As an example, the safety locking member 46 may be connected to the middle of the latching finger body 41 in the height direction, but this is not a limitation.

[0070] As an example, the two claw fingers 49 are located on the outside of the two claw bodies 41. Since the two claw bodies 41 are spaced apart, the side facing each other can be defined as the inside of the claw body 41, and the side facing away from each other can be defined as the outside of the claw body 41. The two claw fingers 49 extend away from their respective claw bodies 41. In this embodiment, the release position of the two movable claws is located on the inside of the gripping position.

[0071] When the movable claw is in the released position, the two claws 40 can be respectively set in the inner space of the two insertion parts. Under the driving action of the telescopic member 43, the movable claws can move away from each other along the extension direction of the guide member 44. When the two claws 40 are in the gripping position, both claws 40 can be inserted into the above-mentioned insertion parts.

[0072] When the elastic element is located on the outside of the claw body 41, it can be a tension spring. Once the claw body 41 leaves the gripping position, the elastic element applies a pulling force to the claw body 41 to return it to the gripping position. When the elastic element is located on the inside of the claw body 41, it can be a compression spring. Once the claw body 41 leaves the gripping position, the elastic element applies a compressive force (pushing force) to the claw body 41 to return it to the gripping position.

[0073] In the event of failure of the telescopic component 43, the two claws can remain in the gripping position under the action of the elastic component, thus improving the reliability of the handling auxiliary tooling.

[0074] Another exemplary embodiment of this disclosure differs from the above embodiment in that the extension direction of the latch fingers 49 is different. When the two latch fingers 49 are located inside the two latch bodies 41 (not shown), the two latch fingers 49 extend towards each other, and the release position of the movable latch is located outside the gripping position.

[0075] When the movable claws are in the released position, the two claws 40 can be respectively positioned in the space outside the two insertion parts. Under the driving action of the telescopic member 43, the movable claws can move closer to each other along the extension direction of the guide member 44 until the two claws 40 are in the gripping position. At this time, the two movable claws are respectively inserted into the two insertion parts, but not limited to this.

[0076] When the elastic element is located on the outer side of the claw body 41, it can be a compression spring. Once the claw body 41 leaves the gripping position, the elastic element applies a compressive force (push force) to the claw body 41 to return it to the gripping position. When the elastic element is located on the inner side of the claw body 41, it can be a tension spring. Once the claw body 41 leaves the gripping position, the elastic element applies a tensile force to the claw body 41 to return it to the gripping position.

[0077] Reference Figures 1 to 3 The handling auxiliary tooling also includes a spring pull block 47, which is connected to the tooling body 10. One end of the elastic element is fixed to the spring pull block 47, but this is not a limitation, so that the elastic element is reliably connected to the tooling body 10, but this is not a limitation. As an example, the elastic element includes a spring, but this is not a limitation.

[0078] The above embodiments are described using the example of the safety locking member 46 including an elastic member, but are not limited thereto. In another exemplary embodiment of this disclosure, the safety locking member 46 may include a locking pin. When the movable claw moves into the predetermined position of the insertion part, the locking pin can lock the movable claw and the tooling body 10, thereby preventing the movable claw from accidentally sliding relative to the tooling body 10 and disengaging from the insertion part, thus improving the reliability of the handling auxiliary tooling. However, this is not the case.

[0079] Specifically, the movable claw and the tooling body 10 are respectively provided with pin holes. When the movable claw is in a predetermined position, the locking pin can be inserted into the pin holes of the movable claw and the tooling body 10, thereby locking the movable claw to the insertion part.

[0080] In an optional embodiment, the safety locking component 46 may further include a controller and a position sensor. The position sensor is used to monitor the position of the movable claw. The controller can control the locking pin to lock the movable claw at the insertion part according to the position information monitored by the position sensor. For example, but not limited to, the position sensor can monitor whether the movable claw has entered the predetermined position of the insertion part. When the movable claw moves to the predetermined position of the insertion part, the position sensor transmits the position information of the movable claw to the controller. At this time, the controller can control the locking pin to insert into the pin hole of the movable claw and the tooling body 10, thereby locking the claw 40 at the insertion part, preventing the movable claw from accidentally disengaging from the insertion part, and improving the reliability of the handling auxiliary tooling.

[0081] This disclosure utilizes a position sensor, a controller, and a locking pin to achieve automatic locking of the locking pin, reducing manual intervention and thus improving the automation level of the handling auxiliary tooling.

[0082] Reference Figure 1 and Figure 2 To improve the reliability of the handling auxiliary tooling, the handling auxiliary tooling may also include multiple positioning parts 32. The multiple positioning parts 32 are connected to the tooling body 10. Each positioning part 32 is provided with a contact surface for contacting the side wall of the power module housing. The multiple positioning parts 32 are spaced apart and surround to form a positioning cavity. Two latches 40 are disposed in the positioning cavity.

[0083] In this embodiment, the power module can be a cuboid structure, and four positioning parts 32 can be provided. The four positioning parts 32 can be used to match the four corners of the top of the power module, thereby realizing the reliable positioning of the power module and the handling auxiliary tooling, but not limited thereto.

[0084] Specifically, the mating surface of the positioning part 32 may include a first mating surface and a second mating surface, and the first mating surface and the second mating surface are arranged at an angle, so that multiple positioning parts are used to position multiple corners of the lifting surface of the housing. As an example, the first mating surface and the second mating surface may be arranged perpendicularly, but are not limited thereto.

[0085] In this embodiment, the first and second mating surfaces of each positioning part 32 can respectively mate with the adjacent sidewalls of the outer peripheral sidewall of the power module, thereby reliably positioning the power module within the positioning cavity. When using the handling auxiliary tooling, the power module can be reliably positioned first by multiple positioning parts 32, and then the movable claws can be driven to move, so that the two claws 40 are respectively inserted into the insertion part, thereby reliably installing the handling auxiliary tooling onto the power module, but this is not a limitation.

[0086] As an example, multiple positioning parts 32 can be connected to the tooling body 10 via positioning mounting base 31, but this is not a limitation. In an optional embodiment, the positioning mounting base 31 can be disposed below the tooling body 10 in the height direction. For example, but not limited to, the positioning mounting base 31 can be connected to the lower part of the tooling body 10 by welding or fastener connection. The positioning parts 32 can be disposed on the side of the positioning mounting base 31 facing away from the tooling body 10. For example, but not limited to, the positioning parts 32 can be fixed to the positioning mounting base 31 by welding, fastener connection, or adhesive bonding, but this is not a limitation.

[0087] This embodiment uses a power module that is roughly rectangular as an example for illustration, but it is not limited to this. When the power module has other shapes, the location of the positioning part 32 and the setting of the contact surface of the positioning part can be arranged according to actual needs, but it is not limited to this.

[0088] As an example, the positioning part 32 can be an elastic component to avoid contact with the power module and thus prevent wear and scratches on the power module, but this is not a limitation. Alternatively, the positioning part 32 can be a nylon component or a rubber component, but this is not a limitation.

[0089] This disclosure uses multiple positioning parts 32 to fit against the outer peripheral sidewall of the power module to hold and position the power module from the outer periphery, and then the claws 40 move relative to each other and insert into the plug-in part, so that the handling auxiliary tooling can be reliably installed on the power module, but is not limited thereto.

[0090] Continue to refer to Figure 1 and Figure 2 The tooling body 10 may include a pair of side beams 22 and a cover plate 21 connected between the pair of side beams 22. The pair of side beams 22 are located outside the two latches 40, the guide 44 is connected between the pair of side beams 22, and the cover plate 21 covers the two latches 40.

[0091] Referring to Figure 3 Figure 3 , in this embodiment, the two side beams 22 are arranged at intervals along the length direction L of the handling auxiliary tooling, and both ends of the guiding member 44 are respectively fixed on the two side beams 22, but not limited thereto.
