[0002] Traction motors are widely used in the railway industry, serving as the traction power units for locomotives and EMUs. As the core drive component of EMU trains, their performance directly impacts the safety and stability of the trains. Therefore, regular maintenance of traction motors is essential to promptly identify and address potential faults and ensure efficient EMU operation.

[0003] Traction motor maintenance involves multiple steps, such as sootblowing the motor surface, transferring the motor from the sootblowing workbench to the disassembly workbench for disassembly, and transferring the disassembled stator and rotor to a dedicated stator and rotor maintenance workbench for maintenance. During this transfer process, specialized support devices are used to support the traction motor, stator, and rotor to ensure stability during transfer. However, due to the variety of traction motor models, and the varying specifications of the stators and rotors within each model, traction motor maintenance workshops must customize a variety of specific support devices based on the model of the traction motor, stator, and rotor. This large number of support devices is difficult to manage, increasing maintenance costs and reducing efficiency.

[0004] Therefore, a supporting device is urgently needed to solve the above problems. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figures 1 to 7 As shown, this embodiment provides a supporting device for supporting the traction motor and its stator and rotor during transportation, which can be applied to supporting traction motors, stators and rotors of different models, thereby reducing the number of supporting devices used, reducing the maintenance cost of the traction motor, and improving the efficiency of the traction motor maintenance.

[0040] See Figure 1 and Figure 2 The supporting device includes a bracket 1, a first supporting mechanism 2 and a second supporting mechanism 3. The bracket 1 is provided with a positioning mechanism 4. The first supporting mechanism 2 and the second supporting mechanism 3 can be selectively installed on the bracket 1 and positioned and installed by the positioning mechanism 4; the first supporting mechanism 2 includes a first supporting seat 21 and a first supporting assembly 22 arranged on the first supporting seat 21. The first supporting seat 21 is detachably connected to the bracket 1. The first supporting assembly 22 is provided with a plurality of mounting grooves 221. The traction motor or stator can be clamped in one or more mounting grooves 221; the second supporting mechanism 3 includes a second supporting seat 31 and a second supporting assembly 32. The second supporting seat 31 is detachably connected to the bracket 1. The second supporting assembly 32 includes two spaced supporting rollers 321. The supporting roller 321 is rotatably arranged on the second supporting seat 31 along its axial direction. The rotor is placed between the two supporting rollers 321. The supporting roller 321 can support the rotor and cooperate with the rotor in rotation.

[0041] The supporting device provided in this embodiment, the first supporting mechanism 2 and the second supporting mechanism 3 can be selectively installed on the bracket 1. When the first supporting mechanism 2 is installed on the bracket 1, the traction motor or stator can be clamped in one or more installation slots 221 of the first supporting assembly 22 according to its own structure, so that the first supporting mechanism 2 can support traction motors and stators of different models during transportation, reducing the number of supporting devices used when transporting traction motors or stators, reducing the maintenance cost of traction motors and stators, and eliminating the need to frequently replace supporting devices when repairing different models of traction motors and stators, thereby improving the efficiency of traction motor and stator maintenance. When the second supporting mechanism 3 is installed on the bracket 1, the rotor is cylindrical and is placed between two supporting rollers 321. The space between the two supporting rollers 321 and the supporting rollers 321 can support rotors of different models during transportation, thereby reducing the number of rotor supporting devices used and the space they occupy, reducing the maintenance cost of the rotor, and eliminating the need to replace the supporting device during maintenance, thereby improving the efficiency of rotor maintenance. In addition, the supporting rollers 321 rotate with the rotor while supporting the rotor, so that the supporting rollers 321 do not affect the rotation of the rotor, ensuring the smooth progress of rotor maintenance. The positioning mechanism 4 enables the first supporting mechanism 2 and the second supporting mechanism 3 to be accurately positioned and placed on the bracket 1, so that the first supporting mechanism 2 and the second supporting mechanism 3 can be accurately transported to the maintenance equipment, which is conducive to improving the efficiency of transportation. The first supporting seat 21 and the second supporting seat 31 are detachably connected to the bracket 1, which can facilitate the replacement of the first supporting mechanism 2 and the second supporting mechanism 3 on the bracket 1.

[0042] Exemplarily, the first supporting seat 21 and the second supporting seat 31 are both made of 20 mm thick steel plates to facilitate the installation of the first supporting assembly 22 and the second supporting assembly 32 .

[0043] Optionally, see Figure 1 and Figure 2 The positioning mechanism 4 includes a push assembly 41 movably arranged on the bracket 1, and the first supporting seat 21 or the second supporting seat 31 is moved along the horizontal transfer direction ( Figure 1 A push assembly 41 is provided on one side of the first supporting seat 21 or the second supporting seat 31 along the X direction), and a limiting member 51 is provided on the other side of the first supporting seat 21 or the second supporting seat 31 along the horizontal transfer direction. When the push assembly 41 located on the side of the first supporting seat 21 or the second supporting seat 31 along the horizontal transfer direction is driven to move along the horizontal transfer direction, the push assembly 41 can contact the first supporting seat 21 or the second supporting seat 31 and push the first supporting seat 21 or the second supporting seat 31 to be pressed against the limiting member 51 to limit the displacement of the first supporting seat 21 or the second supporting seat 31 along the horizontal transfer direction, thereby completing the positioning of the first supporting mechanism 2 or the second supporting mechanism 3 along the horizontal transfer direction; the first supporting seat 21 or the second supporting seat 31 moves along the preset direction ( Figure 1A push assembly 41 is provided on both sides of the first supporting seat 21 or the second supporting seat 31 along the Y direction. When the push assembly 41 located on one side of the preset direction is driven to move along the preset direction, the push assembly 41 can contact the first supporting seat 21 or the second supporting seat 31 and push the first supporting seat 21 or the second supporting seat 31 to press against the push assembly 41 located on the other side of the first supporting seat 21 or the second supporting seat 31 along the preset direction, so as to limit the movement of the first supporting seat 21 or the second supporting seat 31 along the preset direction, thereby completing the positioning of the first supporting mechanism 2 or the second supporting mechanism 3 along the preset direction. The first supporting mechanism 2 or the second supporting mechanism 3 is clamped under the action of multiple push assemblies 41 and will not move, so that the first supporting mechanism 2 or the second supporting mechanism 3 can remain in the current position. The horizontal transfer direction is perpendicular to the preset direction.

[0044] For example, see Figure 1 and Figure 2 The position of the push assembly 41 in the horizontal transfer direction corresponds to the position of the limit member 51, and the positions of the two groups of push assemblies 41 in the preset direction correspond to each other, so that the first supporting seat 21 or the second supporting seat 31 can be subjected to uniform push force along the horizontal transfer direction and the preset direction to improve the positioning accuracy.

[0045] In this embodiment, refer to Figure 1 and Figure 2 The push assembly 41 includes a push member 411 and a pressure block 412. The bracket 1 is provided with a mounting member 11. One end of the push member 411 is threadedly connected to the mounting member 11, and the other end is rotatably engaged with the pressure block 412. The pressure block 412 is movably fixed to the bracket 1. When the push member 411 is driven to rotate, the push member 411 can push the pressure block 412 to move along the horizontal transfer direction or along a preset direction, so that the pressure block 412 contacts and pushes the first support seat 21 or the second support seat 31, thereby achieving the positioning of the first support seat 21 or the second support seat 31. The push member 411 is threadedly connected to the mounting member 11, and the distance of movement of the push member 411 can be accurately controlled, thereby accurately controlling the position of the first support seat 21 and the second support seat 31.

[0046] Exemplarily, the push member 411 is a bolt, and a threaded hole adapted for the bolt is provided on the mounting member 11 . When the bolt is screwed, the bolt moves along its axial direction to push the pressure block 412 .

[0047] Further, see Figure 5 and Figure 6The pressing block 412 is provided with a waist-shaped groove 4121. The supporting device further includes a fastener 52, which passes through the waist-shaped groove 4121 and is fastened to the bracket 1 to secure the pressing block 412 to the bracket 1. When the pushing member 411 pushes the pressing block 412 to move, the fastener 52 moves relative to the waist-shaped groove 4121, allowing the pressing block 412 to move on the bracket 1 while being fixedly connected to the bracket 1. The extending direction of the waist-shaped groove 4121 is the same as the moving direction of the pressing block 412.

[0048] Optionally, see Figure 3 、 Figure 4 and Figure 5 The positioning mechanism 4 also includes multiple groups of positioning components 42 arranged on the bracket 1, and the multiple groups of positioning components 42 are arranged at intervals along the circumference of the first supporting seat 21 or the second supporting seat 31. The first supporting seat 21 and the second supporting seat 31 are both provided with multiple positioning holes 211, and the multiple positioning holes 211 correspond one-to-one to the multiple groups of positioning components 42. The positioning component 42 includes a positioning member 421 and a linear driving member 422. The output end of the linear driving member 422 is connected to the positioning member 421 for driving the positioning member 421 to move vertically and engage with the corresponding positioning hole 211. When the positioning member 421 is inserted into the corresponding positioning hole 211, the positioning member 421 can contact the hole wall of the positioning hole 211 to limit the movement of the first supporting seat 21 or the second supporting seat 31, thereby achieving precise positioning of the first supporting seat 21 or the second supporting seat 31; multiple groups of positioning components 42 can limit the movement of the first supporting seat 21 or the second supporting seat 31 at various positions along its circumference, thereby improving the accuracy of positioning the first supporting mechanism 2 and the second supporting mechanism 3; in addition, the positioning member 421 can be quickly inserted into the positioning hole 211 under the drive of the linear driving member 422, thereby improving the efficiency of positioning the first supporting seat 21 and the second supporting seat 31.

[0049] Exemplarily, the linear drive member 422 is a cylinder, the positioning member 421 is a pin shaft, and a pin sleeve is provided at the positioning hole 211. The pin shaft extends into the pin sleeve under the action of the cylinder. The setting of the pin sleeve can reduce the wear between the pin shaft and the wall of the positioning hole 211, thereby improving the service life of the first support seat 21 and the second support seat 31.

[0050] Exemplarily, the cross-sections of the first supporting seat 21 and the second supporting seat 31 are both rectangular, and four positioning holes 211 are provided, and the four positioning holes 211 are respectively arranged at the four corners of the rectangle.

[0051] Furthermore, the top of the positioning member 421 is set to be a cone. In the process of the positioning member 421 continuously extending upward into the positioning hole 211, the conical surface of the cone contacts and pushes the wall of the positioning hole 211, and then the first supporting seat 21 or the second supporting seat 31 moves slightly under the pushing action, so that multiple positioning members 421 can be inserted into the corresponding positioning holes 211, completing the precise positioning of the first supporting seat 21 and the second supporting seat 31.

[0052] In this embodiment, the support device further includes a sensing element, such as a sensor, disposed on the bracket 1 for sensing the position of the first supporting mechanism 2 or the second supporting mechanism 3. Furthermore, the bracket 1 is provided with a control module 53 electrically connected to both the sensing element and the linear drive member 422. The sensing element is capable of transmitting the position of the first supporting mechanism 2 or the second supporting mechanism 3 to the control module 53, which then controls the opening and closing of the linear drive member 422 based on the position of the first supporting mechanism 2 or the second supporting mechanism 3.

[0053] In other embodiments, the bracket 1 is provided with both a push assembly 41 and a positioning assembly 42, that is, the first supporting mechanism 2 and the second supporting mechanism 3 are doubly positioned to achieve precise positioning of the first supporting mechanism 2 and the second supporting mechanism 3, so as to facilitate other automated operations such as a truss gripper to grab the supported traction motor, stator or rotor.

[0054] Specifically, after the first supporting mechanism 2 or the second supporting mechanism 3 is placed on the bracket 1, the pushing member 411 is first screwed, and the pushing member 411 pushes the pressure block 412 to move along the horizontal transfer direction to press the first supporting seat 21 or the second supporting seat 32 against the limit member 51, or, the pushing member 411 pushes the pressure block 412 to move along the preset direction to press the first supporting seat 21 or the second supporting seat 32 against the pressure block 412 on the other side, completing the preliminary positioning of the first supporting mechanism 2 or the second supporting mechanism 3 along the horizontal transfer direction and along the preset direction; then, the linear driving member 422 is turned on, and the linear driving member 422 drives the positioning member 421 to move upward, and the positioning member 421 is stuck in the positioning hole 211 while being able to drive the first supporting seat 21 or the second supporting seat 32 to move through the positioning hole 211, completing the precise positioning of the first supporting mechanism 2 or the second supporting mechanism 3 on the bracket 1.

[0055] Optionally, see Figure 3The first support assembly 22 includes a plurality of support blocks 222 having different shapes. The mounting slot 221 is formed by one or more support blocks 222. The plurality of support blocks 222 can be formed according to the specifications of the traction motor and stator. The support blocks 222 can then be used to define a plurality of mounting slots 221 of different shapes. This allows for flexible configuration of the position and shape of the mounting slots 221, enabling support for various models of traction motors and stators.

[0056] This embodiment takes the maintenance of the traction motor of the EMU as an example. The traction motor models of the EMU mainly include 4300BF, 5400BF, 6380A and 7380B. The position, shape and size of the support block 222 are determined according to the structure of these four traction motors. Figure 3 The first supporting assembly 22 includes a plurality of U-shaped supporting blocks 222, a plurality of flat supporting blocks 222 and a plurality of cubic supporting blocks 222. These supporting blocks 222 are surrounded by a U-shaped mounting groove 221, a cross-shaped mounting groove 221 and an irregular-shaped mounting groove 221. The legs of the 4300BF traction motor and the 5400BF traction motor can be clamped in the U-shaped mounting groove 221, the legs of the 6380A traction motor can be clamped in the cross-shaped mounting groove 221, and one end of the 7380B traction motor can be clamped in the U-shaped mounting groove 221, and the other end can be clamped in the irregular-shaped mounting groove 221.

[0057] Furthermore, the support block 222 is made of a flexible material, such as nylon. While limiting the position of the traction motor and the stator, the support block 222 can also avoid collision between the traction motor and the stator, thereby preventing damage to the traction motor or the stator during maintenance and transportation.

[0058] Furthermore, the supporting blocks 222 are connected by bolts, which not only ensures the connection effect between the supporting blocks 222 but also facilitates the rapid replacement of the supporting blocks 222 to be suitable for different models of traction motors and stators.

[0059] Optionally, see Figure 4 and Figure 7 A support frame 322 is mounted on the second support seat 31. The second support assembly 32 also includes a connecting shaft 323 fixed to the support frame 322. The support roller 321 is sleeved on the connecting shaft 323 and rotatably engages with the connecting shaft 323. The support frame 322 allows the support roller 321 to be vertically spaced from the second support seat 31, providing sufficient space for the rotor. The support roller 321 rotatably engages with the connecting shaft 323, allowing the support roller 321 to be mounted on the second support seat 31 while also being able to rotate about its axis, facilitating rotor maintenance.

[0060] In this embodiment, the supporting roller 321 is made of a flexible material, such as nylon, which can support the rotor while avoiding collision with the rotor, thereby preventing damage to the rotor during transportation.

[0061] Further, see Figure 4 and Figure 7 The supporting roller 321 and the connecting shaft 323 are connected through a bearing 324 to achieve rotational cooperation between the supporting roller 321 and the connecting shaft 323.

[0062] For example, see Figure 4 The support frame 322 includes support plates respectively arranged on both sides of the connecting shaft 323, and the connecting shaft 323 is fixedly connected to the support plates by bolts.

[0063] Optionally, see Figure 1 、 Figure 2 and Figure 5 The bracket 1 is provided with a rotatable rotating ball 54, and the first supporting seat 21 or the second supporting seat 31 is placed on the rotating ball 54 and rotates in conjunction with the rotating ball 54. During the positioning process, the first supporting seat 21 or the second supporting seat 31 will move relative to the bracket 1, and the rotating ball 54 will rotate under the drive of the first supporting seat 21 or the second supporting seat 31, thereby reducing the friction between the first supporting seat 21 or the second supporting seat 31 and the bracket 1, reducing the wear of the first supporting seat 21 and the second supporting seat 31, and extending the service life of the first supporting mechanism 2 and the second supporting mechanism 3.

[0064] Exemplarily, a bull's eye bearing is provided on the bracket 1 , and the rotating ball 54 is a rolling ball of the bull's eye bearing. The rotating ball 54 is rotatably provided on the bracket 1 through the inner ring and outer ring of the bull's eye bearing.

[0065] Optionally, see Figure 1 and Figure 2 A plurality of lifting rings 56 are provided on the first supporting seat 21 and the second supporting seat 31. The plurality of lifting rings 56 are arranged at intervals along the circumference of the first supporting seat 21 or the second supporting seat 31. The lifting rings 56 are used to lift the first supporting mechanism 2 or the second supporting mechanism 3, so as to realize the transportation of the first supporting mechanism 2 and the second supporting mechanism 3 in various ways. The plurality of lifting rings 56 arranged along the circumference of the first supporting seat 21 or the second supporting seat 31 can ensure the stability of the first supporting seat 21 and the second supporting seat 31 during the lifting process.

[0066] Exemplarily, the cross-sections of the first supporting seat 21 and the second supporting seat 31 are both rectangular, and four hanging rings 56 are provided, and the four hanging rings 56 are respectively arranged at the four corners of the rectangle.

[0067] Optionally, see Figure 1 and Figure 2The first supporting seat 21 and the second supporting seat 31 are both provided with guide wheels 57, and the guide wheels 57 are used to guide the first supporting mechanism 2 or the second supporting mechanism 3 to move along the horizontal transfer direction.

[0068] Exemplarily, three guide wheels 57 are provided on each side of the first supporting seat 21 and the second supporting seat 31 along the preset direction, the three guide wheels 57 are arranged at intervals along the horizontal transfer direction, and the guide wheels 57 are horizontally installed on the first supporting seat 21 and the second supporting seat 31; during the transfer process, the guide wheels 57 can contact the maintenance equipment or the transfer equipment to guide the movement of the first supporting mechanism 2 or the second supporting mechanism 3.

[0069] In this embodiment, the bracket 1 includes two groups of frame structures arranged at intervals along a preset direction, each frame structure is composed of welded plates and profiles. During the transportation process, the transportation equipment such as the automatic guided vehicle 100 can move to the bottom of the plate and connect with the first supporting mechanism 2 or the second supporting mechanism 3 through the gap between the two groups of frame structures to transport the first supporting mechanism 2 or the second supporting mechanism 3.

[0070] Specifically, when the automatic guided vehicle 100 moves the first supporting mechanism 2 or the second supporting mechanism 3 to the positioning mechanism 4, the automatic guided vehicle 100 first moves the first supporting mechanism 2 or the second supporting mechanism 3 upward to avoid the limit member 51, and then the automatic guided vehicle 100 drives the first supporting mechanism 2 or the second supporting mechanism 3 to move along the horizontal transfer direction. After moving to the appropriate position, the automatic guided vehicle 100 drives the first supporting mechanism 2 or the second supporting mechanism 3 to move downward and place it on the bracket 1.

[0071] Furthermore, the bottoms of the first supporting seat 21 and the second supporting seat 31 are both provided with connecting members 311 and connecting holes. The connecting members 311, such as rivets or axle pins, can be inserted into the zero-point locator of the transfer equipment to accurately place the first supporting mechanism 2 or the second supporting mechanism 3 on the transfer equipment; a pin sleeve is provided at the connecting hole for supporting the pallet 101 of the automatic guided vehicle 100. A pin shaft is provided on the pallet 101 supporting the automatic guided vehicle 100. The pin shaft and the pin sleeve can prevent the pallet 101 supporting the automatic guided vehicle 100 from slipping or deviating too much from the first supporting mechanism 2 or the second supporting mechanism 3.
