Description

Technical Field

[0001] This application relates to the field of motor testing technology, and in particular to a motor reversing device. Background Technology

[0002] In the field of rail transit, the traction motor is a core component of rail transit vehicles, and its performance directly affects the operational safety and efficiency of the train. During assembly, the traction motor undergoes multiple rounds of testing and inspection to ensure it meets technical standards.

[0003] For example, after the stator and rotor of the traction motor are installed, but before installing the bearings, the traction motor, which is originally in a vertical position, needs to be rotated 90° to meet the specific requirements of the testing platform for its placement. However, traditional traction motor rotation is done manually, requiring multiple operators, resulting in high labor intensity and low efficiency. Furthermore, the traction motor is prone to damage during rotation due to uneven force or operational errors. Manual rotation also presents significant safety risks. Utility Model Content

[0004] This application provides a motor reversing device to solve the problems of low reversing efficiency and poor safety in motor reversing.

[0005] This application provides a motor reversing device, comprising:

[0009] In one possible implementation, the base includes a seat and two support members, the two support members being disposed at a distance from each other on the seat, and the flip support assembly being connected to both support members.

[0010] In one possible implementation, the flipping support assembly includes a support shaft and at least two bearings, the support shaft being connected to both of the support members, the at least two bearings being spaced apart on the support shaft, the motor being supported on the bearings and flipping relative to the base via the bearings.

[0012] In one possible implementation, the spacing adjustment assembly includes an adjustment screw that extends along the spacing direction between the two supports. The adjustment screw is rotatably mounted on the base and is threadedly connected to at least one of the supports. When the adjustment screw rotates relative to the base, it causes the support to move relative to the other support.

[0013] And / or, the pitch adjustment assembly includes a gear and a rack, the gear being rotatably disposed on one of the base and the support member, and the rack being disposed on the other of the base and the support member, the rack extending along the spacing direction of the two supports members and meshing with the gear, and when the gear rotates, it drives the support member to move relative to the other support member through the rack.

[0014] In one possible implementation, a locking member is further included, movably connected to the base, the locking member being used to secure the support member in the current position.

[0015] In one possible implementation, the support shaft is detachably connected to both of the support members.

[0016] In one possible implementation, the support shaft includes a first shaft and a second shaft, the end of the first shaft facing the second shaft being threadedly connected to the second shaft, and the bearing being connected to at least one of the first shaft and the second shaft.

[0017] In one possible implementation, a limiting member is also included, which is disposed on the base and is used to limit the rotation angle of the motor;

[0018] And / or, it also includes a drive unit connected to the connecting assembly for applying a lifting force to the connecting assembly to drive the motor to rotate via the connecting assembly.

[0019] In one possible implementation, an angle indicator disk and an angle indicator needle are also included. The angle indicator disk is connected to the base, and a plurality of angle scales on the angle indicator disk are spaced apart along the rotation direction of the motor. The angle indicator needle is disposed on the motor and corresponds to the angle indicator disk.

[0020] The motor flipping device provided in this application supports the motor to be flipped on the flipping support component by setting a flipping support component on the base. Under the action of external force, the connecting component drives the motor to flip relative to the base to a preset angle, so that the entire motor flipping does not require the cooperation of multiple people. This not only helps to reduce personnel involvement, but also helps to improve the flipping efficiency and safety of the motor during flipping. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection via an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] The terms "first," "second," "third," "fourth," etc., used in the specification and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0042] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or components is not necessarily limited to those steps or components that are explicitly listed, but may include other steps or components that are not explicitly listed or that are inherent to those processes, methods, products, or apparatuses.

[0043] In the production and assembly process of traction motors for rail transit vehicles, multiple inspection procedures are set up to control product quality and avoid power failures during train operation due to assembly defects. Among them, the assembly accuracy of the stator and rotor in the traction motor is the key link that determines the power transmission efficiency and operational stability of the traction motor. After the stator and rotor are assembled in place and before the bearing bushes are installed, the assembly condition of the traction motor must be inspected.

[0044] The testing requires a dedicated testing platform, which imposes specific requirements on the traction motor's placement based on sensor placement, probe contact methods, and signal acquisition stability. Specifically, the traction motor must be kept horizontal. However, during the stator and rotor assembly process, the traction motor is typically assembled vertically. Therefore, after stator and rotor assembly is complete and before proceeding with this specialized testing, the traction motor must be rotated from its vertical position during assembly to the horizontal position required by the testing platform.

[0045] In existing technologies, the reversing operation of traction motors generally relies on the cooperation of multiple people. Because traction motors are heavy, not only do multiple workers need to work together synchronously, making the operation time-consuming and labor-intensive, thus affecting reversing efficiency, but also, during manual reversing, inconsistent force application can easily lead to tilting or collisions, causing damage to the traction motor. There is also a safety hazard of the traction motor slipping and injuring workers.

[0046] Based on this, this application provides a motor reversing device to solve the problems of low reversing efficiency and poor safety in multi-person motor reversing. The structure of the reversing device is described below with reference to the accompanying drawings.

[0047] like Figure 1 and Figure 2 As shown, the motor flipping device of this application embodiment includes a base 100, a flipping support assembly 200, and a connecting assembly 300. The flipping support assembly 200 is supported on the base 100 and is used to connect the motor 600 to be flipped. The connecting assembly 300 is used to connect to the motor 600 and is configured to drive the motor 600 to flip relative to the base 100 to a preset angle under the action of an external force.

[0048] The motor flipping device of this application embodiment provides a flipping support assembly 200 on the base 100, and supports the motor 600 to be flipped on the flipping support assembly 200. This allows the connecting assembly 300 to drive the motor 600 to flip relative to the base 100 to a preset angle under external force. Therefore, the entire flipping of the motor 600 does not require multiple people to cooperate, which not only reduces personnel involvement but also improves the flipping efficiency and safety of the motor 600 during flipping.

[0049] It should be noted that the motor 600 in this embodiment can be a traction motor 600 used in the assembly process, or a motor 600 that requires flipping in other scenarios.

[0050] like Figure 3 and Figure 4 As shown, the base 100 includes a base body 110 and two support members 120. The two support members 120 are spaced apart on the base body 110, and the flip support assembly 200 is connected to both support members 120.

[0051] The base 110, serving as the bottom support, evenly distributes the weight of the motor 600 to the ground, thus ensuring the structural stability of the base 100 during use. The two spaced-apart support members 120 work together to form a stable support structure, providing a connection base for the tilting support assembly 200. The combination of the base 110 and the two support members 120 prevents the motor 600 from tipping over when it tilts.

[0052] Specifically, the base 100 can be presented Figure 3 The plate-like structure shown can also be formed by connecting multiple beams horizontally and vertically, as long as it ensures good stability of the motor 600 during rotation. The support member 120 can be a support beam or support plate, etc., as long as it meets the connection and usage requirements of the rotation support assembly 200. In this embodiment, the base 110 is made of high-strength steel, and its surface is specially treated to have anti-slip and wear-resistant properties.

[0053] In one possible implementation, such as Figure 7 As shown, the flip support assembly 200 includes a support shaft 210 and at least two bearings 220. The support shaft 210 is connected to both support members 120, and the at least two bearings 220 are spaced apart on the support shaft 210. The motor 600 is supported on the bearings 220 and flips relative to the base 100 via the bearings 220.

[0054] Here, the inner ring of bearing 220 is connected to support shaft 210, and the outer ring of bearing 220 is used to connect motor 600. When motor 600 rotates, the outer ring of bearing 220 can rotate synchronously with motor 600, thereby reducing frictional resistance during the rotation process of motor 600. When the operator drives motor 600 to rotate through connecting assembly 300, only a small external force is needed to drive motor 600 to rotate around support shaft 210. This significantly reduces the difficulty of operation, especially for heavy-duty motor 600, avoiding the problems of rotation jamming and laborious operation caused by excessive friction, making the rotation action more effortless.

[0055] Taking motor 600 as an example, such as Figure 5 and Figure 6 A schematic diagram of the structure of the motor 600 to be flipped is shown. The diagram only shows the structures on the motor 600 related to flipping. Other structures on the motor 600 not shown can be referred to in the prior art.

[0056] One side of the motor 600 has an arc-shaped bearing mounting half-groove 630, which mates with bearing mounting half-groove 630s on other components of the motor 600 to define a bearing mounting groove for mounting bearings. The motor 600 to be flipped is specifically inserted into the flipping support assembly 200 through the bearing mounting half-groove 630, thereby being supported on the flipping support assembly 200.

[0057] like Figure 1 and Figure 2 As shown, the motor 600 is inserted into each bearing 220 via a bearing bush mounting half-groove 630. The cooperation of at least two bearings 220 helps ensure the stability of the motor 600. In this embodiment, the bearings 220 are made of high-quality alloy steel. The diameter of the bearings 220 is selected according to the weight and size of the traction motor 600 to bear its weight and allow for smooth rotation.

[0058] For example, the diameter of the outer ring of bearing 220 is equal to the diameter of the bearing bush mounting half-groove 630. It can be understood that the connection between bearing 220 and motor 600 can be achieved by inserting bearing 220 into the bearing bush mounting groove, or by other methods, as long as it is ensured that the motor 600 to be flipped is connected to the outer ring of bearing 220.

[0059] In this embodiment, the motor reversing device further includes a spacing adjustment component 400, which is connected to at least one support member 120 and is used to adjust the spacing between the two support members 120; the length of the support shaft 210 is adjustable. By adjusting the spacing adjustment component 400 and the length of the support shaft 210, the spacing between the two support members 120 and the length of the support shaft 210 can be adjusted according to the specifications of the motor 600, thereby improving the versatility and flexibility of the motor reversing device in use.

[0060] The structure of the spacing adjustment component 400 will be described below using the example of adjusting only one support member 120. For ease of description, the support member 120 fixed relative to the base 110 will be referred to as support member two 122, and the support member 120 movable relative to the base 110 will be referred to as support member one 121.

[0061] In one possible implementation, such as Figure 3 and Figure 4 As shown, the spacing adjustment assembly 400 includes an adjusting screw that extends along the spacing direction between two support members 120. The adjusting screw is rotatably mounted on the base 110 and is threadedly connected to at least one support member 120. When the adjusting screw rotates relative to the base 110, it causes the support member 120 to move relative to the other support member 120. Here, the support member 120 threadedly connected to the adjusting screw can be moved simply by rotating the adjusting screw, which has the advantage of convenient operation.

[0062] In terms of specific structure, such as Figure 3 As shown, a groove 111 is provided on the base 110, extending along the interval direction of the two support members 120, and a slider 1211 is provided at the bottom of the first support member 121. The first support member 121 is slidably disposed in the groove 111 by the slider 1211, thereby moving closer to or further away from the second support member 122, and thus adjusting the distance between the two support members 120.

[0063] The adjusting screw is rotatably mounted on the base 110, but cannot move relative to the base 110 along its axial direction. The adjusting screw passes through and is threadedly connected to the slider 1211. By rotating the adjusting screw, the slider 1211 slides along the groove 111 via the threaded structure between the adjusting screw and the slider 1211, thereby causing the support member 121 to move closer to or further away from the support member 222. To facilitate operation of the adjusting screw, an operating handle 410 is provided at the end of the adjusting screw located outside the base 110. In addition to the operating handle 410, a drive motor can also be installed on the support member 121 to drive the adjusting screw. The use of a drive motor further reduces manual intervention time and labor intensity.

[0064] The adjusting screw's rotational motion is converted into the linear motion of the slider 1211, driving the support member 121 to move along the slide groove 111. By rotating the adjusting screw, the operator causes the slider 1211 to slide along the slide groove 111 under the action of the thread, thereby precisely adjusting the distance between the two support members 120. The adjusting screw's design enables precise adjustment of the distance between the two support members 120. Driving the slider 1211 by rotating the adjusting screw avoids errors that might occur with manual pushing, ensuring that the distance between the two support members 120 matches the dimensions of the motor 600, further improving the versatility and ease of operation of the motor tilting device.

[0065] In one possible implementation, such as Figure 3 As shown, the motor reversing device also includes a locking member 113, which is movably connected to the base 110. The locking member 113 is used to fix the support member 120 in its current position. By setting the locking member 113, it is beneficial to fix the moved support member 121 to the base 110, thereby improving the stability of the distance between the two support members 120. The current position specifically refers to the position of the support member 121 after it has moved into place.

[0066] In specific implementation, the locking element 113 can be a bolt. The base 110 has multiple threaded holes 114 communicating with the slide groove 111, and these threaded holes 114 are spaced apart along the extension direction of the slide groove 111. The bolt is threadedly connected to any one of the threaded holes 114. One end of the bolt extends into the slide groove 111 and abuts against the slider 1211, thereby locking the moved slider 1211 onto the base 110, thus locking the support element 121 onto the base 110. Using a bolt for the locking element 113 here has the advantage of ease of operation.

[0067] In another possible embodiment, the pitch adjustment assembly 400 in this application includes a gear and a rack. The gear is rotatably disposed on one of the base 110 and the support member 120, and the rack is disposed on the other of the base 110 and the support member 120. The rack extends along the spacing direction of the two supports 120 and meshes with the gear. When the gear rotates, it drives the support member 120 to move relative to the other support member 120 through the rack.

[0068] The gear and rack mechanism here offers advantages such as high transmission efficiency and good stability, facilitating the adjustment of the distance between the two support members 120. Furthermore, the gear and rack have a good self-locking effect; once support member 121 is in position, the gear and rack mechanism locks it onto the base 110. The high transmission efficiency of the gear and rack improves the stability and accuracy of the support member 120's position adjustment.

[0069] In a specific implementation, taking the rack arranged on the base 110 as an example, the rack is located on at least one side of the slide groove 111, and the gear is rotatably set at the bottom of one side of the support member 121 and meshes with the gear. During operation, the gear can be driven to rotate manually, or a motor 600 can be installed on the support member 121 to drive the gear to rotate.

[0070] It should be noted that in this embodiment, both support members 120 can also be moved relative to the base 110. In this case, there are two adjusting screws, which are threadedly connected to the sliders 1211 on each support member 120. By rotating the adjusting screws, the position of the corresponding support member 120 on the base 110 can be adjusted, thereby achieving the effect of adjusting the distance between the two support members 120.

[0071] Each gear is respectively set on each support member 120, and the rack is also set corresponding to each support member 120. By rotating the gear, the position of the corresponding support member 120 on the seat 110 can be adjusted, thereby achieving the effect of adjusting the distance between the two support members 120.

[0072] In practice, the number of adjusting screws, gears, and racks can be determined according to usage requirements. In some embodiments, one of the support member 121 and the support member 122 is adjusted by adjusting screws, while the other is adjusted by gears and racks. In this case, the distance between the two support members 120 can also be adjusted.

[0073] It is understandable that, based on the design concept of the spacing adjustment component 400, in addition to the aforementioned adjusting screw or gear and rack, other structures with spacing adjustment can be used to realize the spacing adjustment between the two support members 120, which will not be described in detail again.

[0074] In this embodiment, the support shaft 210 and both support members 120 are detachably connected. This facilitates adjustment of the distance between the two support members 120 and the length of the support shaft 210. Furthermore, the detachable connection of the support shaft 210 to both support members 120 facilitates replacement and maintenance of the support shaft 210, thereby reducing maintenance costs.

[0075] In some possible implementations, both ends of the support shaft 210 are respectively inserted into each support member 120. The insertion connection method is simple and facilitates the connection and disassembly between the support shaft 210 and the corresponding support member 120. Specifically, in terms of structure, as... Figure 3 As shown, each support member 120 has a mounting groove 123 on its top. The mounting groove 123 is semi-circular and has an open top. Both ends of the support shaft 210 are inserted into the mounting groove 123 from top to bottom.

[0076] In addition, such as Figure 3 and Figure 4 As shown, each support member 120 is also provided with a limiting plate 124, which abuts against the end of the support shaft 210, so that the support shaft 210 is located between the two limiting plates 124, thereby restricting the axial movement of the support shaft 210 and thus improving the stability and reliability of the support shaft 210 in use. Furthermore, reinforcing plates 112 are connected to both sides of the second support member 122 and between the support body 110. One end of each reinforcing plate 112 is connected to the second support member 122, and the other end is connected to the support body 110. The reinforcing plates 112, the support body 110, and the second support member 122 form a triangular arrangement to improve the structural strength and stability of the second support member 122.

[0077] It should be noted that, in addition to plug-in connection, the connection between the support shaft 210 and the support member 120 can also be any other method that allows the support shaft 210 to be detachably connected to the support member 120.

[0078] In one possible implementation, such as Figure 7 and Figure 8 As shown, the support shaft 210 includes a first shaft body 211 and a second shaft body 212. The end of the first shaft body 211 facing the second shaft body 212 is connected to the second shaft body 212 by a thread. The bearing 220 is connected to at least one of the first shaft body 211 and the second shaft body 212.

[0079] Here, the first shaft 211 and the second shaft 212 are threaded together, allowing the total length of the support shaft 210 to be adjusted by rotation. This facilitates adjusting the spacing between the two support members 120 according to the spacing adjustment component 400, without needing to replace the entire support shaft 210. It also makes the length adjustment of the support shaft 210 convenient and reliable; the threaded structure allows for length adjustment without complex tools, and tightening creates a stable connection. By adjusting the length of the support shaft 210, the same support shaft 210 can be adapted to different specifications of motors 600, reducing the types of spare parts for the support shaft 210. Furthermore, the threaded connection structure is simple, resulting in low processing and maintenance costs.

[0080] In terms of specific structure, a threaded groove 2121 is provided at one end of the first shaft 211 facing the second shaft 212, and an axially protruding threaded post 2111 is provided at one end of the second shaft 212 facing the first shaft 211. The outer circumferential surface of the threaded post 2111 has external threads. The first shaft 211 and the second shaft 212 are threadedly connected to the threaded groove 2121 via the threaded post 2111. Specifically, when the threaded length of the threaded post 2111 and the threaded groove 2121 increases, the length of the support shaft 210 decreases; conversely, when the threaded length of the threaded post 2111 and the threaded groove 2121 decreases, the length of the support shaft 210 increases.

[0081] To improve the threaded connection effect of the threaded post 2111 and the threaded groove 2121 and prevent the length of the support shaft 210 from being adjusted after the length adjustment is completed, a bolt can also be threaded onto the second shaft 212. The bolt is inserted into the threaded groove 2121 radially along the second shaft 212 and abuts against the outer periphery of the threaded post 2111 after it is threaded into place. This restricts the relative axial movement of the first shaft 211 and the second shaft 212, thereby improving the reliability of the support shaft 210.

[0082] It is understandable that the length adjustment of the support shaft 210 is not limited to the threaded connection between the first shaft 211 and the second shaft 212; the length adjustment method of the support shaft 210 can also be determined according to usage requirements. When two bearings 220 are arranged, one bearing 220 is set on the first shaft 211, and the other bearing 220 is set on the second shaft 212. Of course, the position of the bearings 220 can also be adjusted according to the length of the first shaft 211 and the second shaft 212.

[0083] In specific implementation, the other end of the first shaft 211, relative to the end with the threaded post 2111, is inserted into the mounting groove 123 on the support member 121. The other end of the second shaft 212, relative to the end with the threaded groove 2121, is inserted into the mounting groove 123 on the support member 222.

[0084] In addition, the motor reversing device in this embodiment also includes a limiting member 125, which is disposed on the base 100 and is used to limit the reversing angle of the motor 600. The limiting member 125 helps to ensure that the motor 600 is reversed into position and prevents the motor 600 from over-reversing. Moreover, the limiting member 125 can also support the motor 600 after it has been reversed into position, so that the motor 600 is kept in the reversed state.

[0085] In terms of specific structure, such as Figure 2 and Figure 3 As shown, three limiting members 125 are spaced apart on the base 110, arranged in a triangular pattern, which helps to improve the limiting effect on the motor 600. The limiting members 125 can be limiting cylinders, or other structural forms. In addition, the number of limiting members 125 can be increased or decreased according to the usage requirements.

[0086] It should be noted that the rotation angle of the motor 600 in this application can be 90°, or the rotation angle of the motor 600 can be adjusted according to usage requirements. The height of the limiting member 125 is determined according to the required rotation angle to ensure that the limiting member 125 can limit the rotation of the motor 600 when it is in the correct position. In addition, a buffer layer can be provided on the support surface at the top of the limiting member 125. The buffer layer is a rubber buffer layer, which absorbs the impact force when the motor 600 contacts the limiting member 125 through elastic deformation, reducing mechanical vibration damage to the structure of the motor 600.

[0087] In one possible implementation, such as Figure 1 As shown, the connecting assembly 300 includes at least two ropes 310. The use of at least two ropes 310 in the connecting assembly 300 facilitates connection to the motor 600 from different positions, forming multi-point coordinated constraints, thereby improving the stability of the motor 600 during rotation. When an external force is applied to the ropes 310, the motor 600 can be rotated relative to the base 100 via the ropes 310.

[0088] In practical implementation, the rope 310 can be made of high-strength alloy steel wire rope, which not only has high strength but also good flexibility during the rotation of the motor 600. To facilitate the connection between the rope 310 and the motor 600, multiple connection points 610 are provided on the top and side of the motor 600. For example... Figure 1 As shown, connection point 610 is a connection hole or connection groove. The number of ropes 310 can be two, three, or more. One end of each rope 310 is hooked to connection point 610 via a hook, and the other end is used to bear external force. The connection method between the hook and the rope 310 can refer to existing technology, as long as it ensures good connection reliability between the hook and the rope 310.

[0089] This facilitates the connection and disconnection of the rope 310 from the motor 600, and also improves the flipping efficiency. The rope 310, after being connected to the connection point 610, should have good connection reliability to ensure good stability of the motor 600 during the flipping process. For example, when there are three ropes 310, the three ropes 310 are connected to three connection points 610 arranged in a triangle; when there are two ropes 310, the two ropes 310 are connected to two connection points 610 located on opposite sides of the motor 600, respectively.

[0090] like Figure 1 and Figure 2 As shown, the motor flipping device in this embodiment of the application further includes a driving member 500, which is connected to the connecting component 300 and is used to apply a lifting force to the connecting component 300 so as to drive the motor 600 to flip through the connecting component 300.

[0091] Here, by setting the drive component 500 to drive the motor 600 to rotate, it is easier to reduce the degree of human intervention and improve the rotation efficiency. Compared with the problem of manually pulling the rope 310, which requires overcoming the gravity of the motor 600 and relying on physical strength, the drive component 500 can provide a stable and continuous lifting force without requiring the operator to expend physical strength.

[0092] In addition, the lifting force of the drive component 500 can be controlled. For example, the magnitude and speed of the drive force of the drive component 500 can be adjusted according to the weight of the motor 600 and the flipping requirements. This helps to avoid the flipping jam caused by uneven force during manual operation, making the flipping process of the motor 600 smoother and further shortening the single flipping time, thereby improving the flipping efficiency.

[0093] In practice, one end of the rope 310 is connected to the motor 600, and the other end is connected to the drive unit 500. The lifting force of the drive unit 500 acts on the rope 310, thereby tensioning the rope 310, and the lifting force drives the rope 310 to move, which in turn drives the motor 600 to rotate. The drive unit 500 here can be a bridge crane or an electric hoist, etc.

[0094] The drive unit 500 has a hoisting mechanism. After the drive unit 500 is started, the rope 310 is in a tensioned state. Then, the hoisting mechanism unwinds the rope 310, and the motor 600, under its own weight, rotates downward around the support shaft 210. Due to the shift in the center of gravity of the motor 600, the tension of the rope 310 is converted into a rotation torque, driving the motor 600 to rotate.

[0095] Multiple ropes 310 are connected to the same winch mechanism. The multiple connection points 610 of the motor 600 have taken into account the force balance during the flipping process when they are connected to the ropes 310, so as to ensure that no excessive deflection torque is generated during the flipping process.

[0096] Furthermore, the rope 310 is in a taut state during the rotation of the motor 600. When the winch mechanism unwinds the rope 310, the motor 600 rotates downwards due to its own weight. When the winch mechanism winds up the rope 310, the lifting force of the rope 310 overcomes the weight of the motor 600, causing the motor 600 to rotate upwards.

[0097] This not only facilitates the rotation of the motor 600 around the axis of the support shaft 210 via the rope 310, but also allows the motor 600 to be supported by the limiting member 125 after it has rotated into position, thus changing the connection position between the rope 310 and the motor 600. This enables the driving member 500 to apply a driving force to the rope 310, maintaining the rotated motor 600 in its rotated position as it is moved to the inspection table, thereby further improving inspection efficiency.

[0098] like Figure 1 and Figure 2As shown, the motor flipping device of this embodiment further includes an angle indicator disk 126 and an angle indicator needle 620. The angle indicator disk 126 is connected to the base 100, and a plurality of angle scales on the angle indicator disk 126 are spaced apart along the flipping direction of the motor 600. The angle indicator needle 620 is disposed on the motor 600 and corresponds to the angle indicator disk 126.

[0099] Here, the angle indicator needle 620 rotates together with the motor 600, and the angle indicator disk 126 is connected to the base 100. By coordinating the angle indicator needle 620 with the scale on the angle indicator disk 126, the rotation angle of the motor 600 can be clearly indicated, allowing operators to easily monitor the rotation status of the motor 600 in real time. The scale on the angle indicator disk 126 is spaced along the rotation direction of the motor 600. Operators can refer to the scale on the angle indicator disk 126 to rotate the motor 600 to the required angle according to specific work needs, thus improving the accuracy of the motor 600's rotation.

[0100] In terms of specific structure, the angle indicator disk 126 is connected to a support member 120. The angle indicator disk 126 is circular or semi-circular, with multiple angle scales spaced apart along the rotation direction of the motor 600. The rotation direction of the motor 600 is centered on the axis of the support shaft 210. The angle indicator needle 620 is needle-shaped and extends radially along the support shaft 210 onto the motor 600. When the motor 600 rotates, the angle indicator needle 620 rotates with the motor 600, while the angle indicator disk 126 remains stationary. The operator can visually understand the rotation angle of the motor 600 by observing the scale indicated by the angle indicator needle 620 on the angle indicator disk 126, thus determining the rotation angle of the motor 600.

[0101] Alternatively, the angle indicator 126 can be directly connected to the support shaft 210, and the angle indicator needle 620 can be set on the outer ring of the bearing 220. In this case, the angle indicator 126 and the angle indicator needle 620 can be used to check the rotation angle of the motor 600.

[0102] In this embodiment, the rotation angle of the motor 600 is visually displayed through physical markings using the angle indicator dial 126 and the angle indicator needle 620. This allows operators to monitor the rotation process in real time, avoiding over- or under-rotation due to lack of experience. Furthermore, the mechanical contact design of the limiting member 125 further ensures that the motor automatically stops when it reaches the target angle (e.g., 90°), preventing equipment slippage or damage caused by operational errors.

[0103] By introducing a dual mechanism of physical feedback and mechanical limit, this design effectively addresses the drawback of the motor-driven reversing device relying on subjective judgment, thereby improving the accuracy and safety of the reversing operation. Simultaneously, the inclusion of the limit component 125 reduces reliance on operator skill.

[0104] In this embodiment of the invention, the motor reversing device first adjusts the distance between the two support members 120 according to the specifications of the motor 600 using the distance adjustment component 400, and then locks it with the locking member 113. Next, the length of the support shaft 210 is adjusted, and the support shaft 210 is installed on the two support members 120.

[0105] Next, the bearing bush of motor 600 is installed in the mounting groove 630 onto bearing 220. The bridge crane is then operated to slowly lower the hook at the bottom of rope 310 via the winch mechanism and hook it onto connection point 610 at the top of motor 600, ensuring a secure connection. The bridge crane is then operated to slowly raise the hook, causing rope 310 to become taut. Then, motor 600 is allowed to rotate downwards around the axis of support shaft 210 under the influence of gravity.

[0106] During the rotation process, carefully observe the position and status of motor 600 to ensure stability and safety. When motor 600 rotates to the preset angle (e.g., 90°), motor 600 abuts against limit piece 125. When angle indicator needle 620 rotates 90°, motor 600 can no longer rotate, indicating that motor 600 has rotated to the correct position. Next, release the hook on rope 310 from motor 600 and hook rope 310 to connection point 610 on the upward-facing side of the rotated motor 600. Finally, the bridge crane moves the rotated motor 600 to the testing platform.

[0107] After completing the testing of motor 600 on the testing platform, motor 600 needs to be removed and rotated after being removed from the testing platform. Specifically, operate the bridge crane to slowly lower the hook via rope 310 and hook it onto motor 600, ensuring a secure connection. Operate the bridge crane to slowly lower the hook via rope 310, causing motor 600 to rotate around support shaft 210 under gravity. During the rotation process, carefully observe the position and status of motor 600 to ensure stability and safety. When motor 600 rotates to the vertical position, the bridge crane stops moving the hook downwards, disconnects it from motor 610, and finally removes motor 600 from bearing 220, completing the rotation operation after being removed from the testing platform.

[0108] The motor flipping device of this application embodiment includes a flipping support assembly 200 and a connecting assembly 300 on a base 100. The flipping support assembly 200 includes a support shaft 210 and at least two bearings 220, allowing external force to flip the motor 600 around the axis of the support shaft 210 via the connecting assembly 300. Compared to methods that rely entirely on multiple people for flipping, this reduces manual intervention, improves flipping efficiency, and provides better flipping safety. Verification shows that using the motor flipping device of this application can reduce the average flipping time from over 20 minutes using traditional methods to 8 minutes, while simultaneously reducing the damage rate of the motor 600 from over 10% to below 2%.

[0109] Secondly, the adjustable spacing between the two support members 120 on the base 100 and the adjustable length of the support shaft 210 facilitate adjustment according to the specifications of the motor 600, enabling the motor flipping device to flip motors 600 of different specifications, thereby improving the flexibility and versatility of the motor flipping device.

[0110] The motor tilting device of this application embodiment has a simple structure, is easy to arrange, implement, and maintain. Tilting is achieved by connecting the motor 600 to a bridge crane, eliminating the need for complex mechanical structures and control systems, making operation convenient and quick. It is applicable to traction motors 600 of different sizes and weights, demonstrating strong versatility.

[0111] During the motor 600's tilting process, the bridge crane precisely controls and the tilting support assembly 200 supports the motor 600, ensuring safe and reliable operation. Furthermore, the entire motor tilting device has a simple structure, making it easy to install, implement, and maintain. Tilting is achieved by connecting the bridge crane to the motor 600, eliminating the need for complex mechanical structures and control systems, resulting in convenient and quick operation.
