Description

Technical Field

[0001] The invention belongs to the technical field of motor stator wire removal devices, and particularly relates to a single-shaft motor stator wire removal device and method. Background Art

[0002] After the coils of some motor stator windings fail and cannot be repaired, the stator frame needs to be recycled after wire removal and then re-wound.

[0003] The method of using a crane for wire pulling and removal: Heat the stator to be wire removed to 300 °C and place it on an open area, and use a crane assisted by a steel wire rope to pull the motor winding coils. During the pulling process, it is possible that the motor stator is lifted by a huge traction force to be nearly suspended and then dropped. After removing 2 or 3 windings, the stator needs to be turned over flat to change the slot for continuous pulling after multiple pullings. This process poses a safety threat to personnel and there is a risk of being injured or scalded by the stator. In this context, it is necessary to design and manufacture a device to solve the above problems and standardize the wire removal operation.

[0004] The usage process breakdown of the existing wire removal devices on the market: ① Pass the main shaft through the motor stator; ② Lift the stator and the main shaft together to the specified area on the workbench; ③ Install the fixing mechanisms on both sides of the main shaft; ④ Fix the motor stator; ⑤ Use the main shaft to rotate and twist the wires for wire removal. During the wire removal process, the removed wires need to be taken off. Since it is fixed at both ends, the coil needs to be cut separately or straightened and then taken off from the main shaft; ⑥ After wire removal, remove the fixing mechanisms on both sides of the main shaft; ⑦ Loosen the stator; ⑧ Lift the stator and the main shaft together and remove; ⑨ Pull out the main shaft from the stator.

[0005] This device is cumbersome to use, with low installation and disassembly efficiency. There is a risk of damaging the stator core when the main shaft passes through the stator. The removed wires are wound around the main shaft. Since the main shaft is fixed at both ends and the twisted wires are fixed to the main shaft, it is difficult to peel off the coil from the main shaft, which affects the wire removal speed. Summary of the Invention

[0006] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a single-shaft motor stator wire removal device and method, which can conveniently take out the removed coils and correspondingly improve the wire removal efficiency.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A single-output shaft type motor stator wire removal device, comprising a base, on which a driving mechanism bracket, a transmission bracket and a steel plate platform are sequentially installed. A driving mechanism is installed on the driving mechanism bracket, the output end of the driving mechanism is connected with a transmission mechanism, the other end of the transmission mechanism is connected with a main shaft, the main shaft is rotationally connected to the transmission bracket, and fixed anchor points are arranged on the steel plate platform. The motor stator is installed on the steel plate platform through the fixed anchor points, and the main shaft extends into the motor stator; it also includes a wire rope and a clamping plate. One end of the wire rope is provided with a ring, and two clamping grooves are arranged at the end of the main shaft away from the transmission mechanism. The ring passes through the two clamping grooves and is sleeved on the main shaft. The other end of the wire rope passes through the clamping plate to form a rope loop, and the rope loop is sleeved on the nose of the coil of the motor stator.

[0009] Only one end of the main shaft of the present invention is fixed through the transmission mechanism, and the other end is unobstructed; the ring of the wire rope passes through the two clamping grooves and is sleeved on the main shaft. Thus, when the wire rope pulls out the coil from the iron core slot of the motor stator, the ring can be removed from the main shaft from the open end of the main shaft, and then the wire rope can be pulled out to pull out the coil from the motor stator. There is no obstruction on the side of the motor stator corresponding to the open end of the main shaft, and the wire rope is not blocked by the main shaft, so that the ring of the wire rope can be removed from the main shaft, and the wire rope and the coil can be completely separated from the main shaft, which is convenient for quickly taking out the coil. Since the main shaft has a single-side output shaft and the wire rope can be removed from the main shaft, during the process of taking out the coil, there is no need to separately cut the coil or straighten the coil and then remove it from the main shaft.

[0010] As a preferred solution of the present invention, the length of the wire rope is greater than the radius of the iron core of the motor stator. The ring on the wire rope can pass through the two clamping grooves and be sleeved on the main shaft, and the rope loop can be connected to the nose of the coil.

[0011] As a preferred solution of the present invention, at least three rope holes are arranged on the clamping plate, and the wire rope passes through all the rope holes in sequence; the wire rope first passes out of the side of the clamping plate away from the main shaft, and then passes back through the clamping plate, leaving a rope loop. After the wire rope passes through several rope holes on the clamping plate in sequence, the end of the wire rope can form a rope loop. The rope loop can be hung on the nose of the coil to ensure that the wire rope can pull the coil. When pulling the wire rope, the wire rope is locked with at least three rope holes on the clamping plate to avoid the rope loop being disengaged from the clamping plate, and the rope loop is reliably connected to the nose of the coil.

[0012] As a preferred solution of the present invention, the driving mechanism includes a driving motor, the output end of the driving motor is connected with a cycloidal reducer, the output end of the cycloidal reducer is connected with the transmission mechanism, and the driving motor and the cycloidal reducer are installed on the driving mechanism bracket.

[0013] As a preferred embodiment of the present invention, the driving mechanism bracket includes a driving bottom plate fixed to the base. Two driving vertical frames are fixed on the driving bottom plate. A number of driving mounting holes are vertically distributed on the driving vertical frames. A driving channel steel is installed on the driving vertical frames through one of the driving mounting holes. A driving mounting plate is installed between the two side driving channel steels. The driving motor and the cycloidal reducer are installed on the driving mounting plate.

[0014] A number of driving mounting holes with different heights are provided on the driving vertical frames, and the driving mounting plate can be adjusted up and down within the stroke to match, so that the height of the driving mechanism matches the height of the main shaft. The driving channel steel is fixed to the driving vertical frames by high-strength bolts, reducing the height difference between the driving mechanism and the main shaft and reducing the bending angle of the universal coupling. The adjustable height of the driving motor is 500 - 1100 mm.

[0015] As a preferred embodiment of the present invention, the transmission mechanism includes a universal coupling. One end of the universal coupling is connected to the output end of the driving mechanism, and the other end of the universal coupling is connected to a transmission shaft. The transmission shaft is rotatably connected to the transmission bracket, and the other end of the transmission shaft is connected to the main shaft.

[0016] As a preferred embodiment of the present invention, the transmission bracket includes a transmission bottom plate fixed to the base. A vertical frame is fixed on the transmission bottom plate. Guide grooves are provided on both sides inside the vertical frame. A bearing mounting seat is sleeved between the two side guide grooves. The transmission shaft is installed in the bearing mounting seat through bearings. A number of vertically distributed transmission mounting holes are provided on the vertical frame, and the bearing mounting seat is installed on the vertical frame through one of the transmission mounting holes.

[0017] The bearing mounting seat reliably supports the transmission shaft, ensuring unilateral fixation of the transmission shaft to the main shaft. Different heights of transmission mounting holes are provided on the vertical frame, and the bearing mounting seat can be adjusted up and down in height and fixed by high-strength bolts at the determined position of the transmission mounting hole. By adjusting the height of the transmission shaft, the height of the main shaft is correspondingly adjusted to make the main shaft adapt to different motor stator center heights. The adjustment range corresponding to the motor center height is 300 - 1300 mm. For motor stators with a lower center height, the method of raising the motor stator can be adopted to adapt to this wire removal device.

[0018] As a preferred embodiment of the present invention, an anchor nut is fixed at the fixed anchor point, and the fixed mounting position of the motor stator and the anchor nut are connected by bolts.

[0019] A method for removing the wire of a single-output shaft type motor stator includes the following steps:

[0020] S1: According to the center height of the motor stator, adjust the height of the main shaft and the driving mechanism to a suitable position;

[0021] S2: Lift the motor stator through the main shaft and place it on the steel plate platform;

[0022] S3: Fix the motor stator to the fixed anchor point;

[0023] S4: Pass the ring of the winch rope through the two card slots and then sleeved on the main shaft, and connect the coil nose to the winch rope through a rope buckle;

[0024] S5: The driving mechanism drives the main shaft to rotate through the transmission mechanism. The main shaft winds and tightens the winch rope to the main shaft, and the winch rope pulls out the coil from the iron core slot of the motor stator;

[0025] S6: When the coil is completely pulled out of the motor stator, the driving mechanism stops;

[0026] S7: Remove the ring from the main shaft, pull the winch rope, and pull out the coil through the winch rope;

[0027] S8: Repeat steps S4 to S7 until all coils are pulled out;

[0028] S9: Remove the motor stator from the fixed anchor point of the steel plate platform and lift the motor stator off.

[0029] As a preferred solution of the present invention, in step S6, when the coil is completely pulled out of the motor stator, the main shaft is stopped in time and the main shaft is reversed by an appropriate number of turns to facilitate the removal of the ring.

[0030] The beneficial effects of the present invention are as follows:

[0031] Only one end of the main shaft of the present invention is fixed through the transmission mechanism, and the other end is unobstructed; the ring of the winch rope passes through the two card slots and is sleeved on the main shaft. Thus, after the winch rope pulls out the coil from the iron core slot of the motor stator, the ring can be removed from the main shaft at the open end of the main shaft, and then the coil can be pulled out of the motor stator by pulling out the winch rope. There is no obstruction on one side of the motor stator corresponding to the open end of the main shaft, and the winch rope is not blocked by the main shaft. Therefore, the ring of the winch rope can be removed from the main shaft, and the winch rope and the coil can be completely separated from the main shaft, which is convenient for quickly removing the coil. Since the main shaft has a single-sided output shaft and the winch rope can be removed from the main shaft, during the process of removing the coil, there is no need to separately cut the coil or straighten the coil and then remove it from the main shaft.

Specific embodiments

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0043] Such as Figures 1 to 8As shown in the figure, the single-output-shaft motor stator wire removal device of this embodiment includes a base 1. A driving mechanism support 2, a transmission support 3, and a steel plate platform 4 are sequentially installed on the base 1. A driving mechanism 5 is installed on the driving mechanism support 2. The output end of the driving mechanism 5 is connected to a transmission mechanism 6. The other end of the transmission mechanism 6 is connected to a main shaft 7. The main shaft 7 is rotatably connected to the transmission support 3. A fixed anchor point 41 is provided on the steel plate platform 4. The motor stator 8 is installed on the steel plate platform 4 through the fixed anchor point 41. The main shaft 7 extends into the motor stator 8. It also includes a wire rope 9 and a clamping plate 91. One end of the wire rope 9 is provided with a ring 92. Two clamping grooves 71 are provided at the end of the main shaft 7 away from the transmission mechanism 6. The ring 92 passes through the two clamping grooves 71 and is sleeved on the main shaft 7. The other end of the wire rope 9 passes through the clamping plate 91 to form a rope loop 93. The rope loop 93 is sleeved on the nose of the coil 81 of the motor stator 8.

[0044] In the present invention, only one end of the main shaft 7 is fixed through the transmission mechanism 6, and the other end is unobstructed. The ring 92 of the wire rope 9 passes through the two clamping grooves 71 and is sleeved on the main shaft 7. Thus, after the wire rope 9 pulls out the coil 81 from the iron core slot of the motor stator 8, the ring 92 can be removed from the main shaft 7 from the open end of the main shaft 7, and then the coil 81 can be pulled out of the motor stator 8 by pulling out the wire rope 9. There is no obstruction on the side of the motor stator 8 corresponding to the open end of the main shaft 7. The wire rope 9 is not obstructed by the main shaft 7. Therefore, the ring 92 of the wire rope 9 can be removed from the main shaft 7, and the wire rope 9 and the coil 81 can be completely separated from the main shaft 7, which is convenient for quickly removing the coil 81. Since the main shaft 7 has a single-side output shaft and the wire rope 9 can be removed from the main shaft 7, during the process of removing the coil 81, there is no need to separately cut the coil 81 or straighten the coil 81 and then remove it from the main shaft 7.

[0045] Specifically, as Figure 3 shown, the base 1 includes a bottom plate frame welded by channel steel. High-quality channel steel with a width of 100 mm is selected for welding. Two transmission supports 3 with adjustable heights for fixing the transmission shaft 62, one driving mechanism support 2 with adjustable height, and a steel plate platform 4 for installing the motor stator 8 are all fixedly installed on the bottom plate frame. High-quality channel steel with a width of 126 mm is selected as the main material of the transmission support 3, and it is formed by welding and using fasteners for connection. High-quality channel steel with a width of more than 126 mm is selected as the main material of the driving mechanism support 2, and it is formed by welding and using fasteners for connection. The material of the steel plate platform 4 with the fixed anchor point 41 is Q235.

[0046] Specifically, as Figure 6 shown, the driving mechanism 5 includes a driving motor 51. The output end of the driving motor 51 is connected to a cycloid reducer 52. The output end of the cycloid reducer 52 is connected to the transmission mechanism 6. The driving motor 51 and the cycloid reducer 52 are installed on the driving mechanism support 2.

[0047] The driving mechanism 5 further includes an electric control cabinet, which is electrically connected to the driving motor 51. The electric control cabinet has a remote control function, and can control the start / stop, forward / reverse rotation of the driving motor 51 through a remote control, and can set the maximum rotation speed and acceleration magnitude of the main shaft 7. The driving motor 51 selects a YE2 type high-efficiency asynchronous motor with a rated power of 11 kw, a rated torque of 108 N·m, and a rated speed of 970 r / min. The cycloid reducer 52 selects an XWY8-87 type cycloid pinwheel reducer with a reduction ratio of 87. After the driving motor 51 is decelerated by the reducer, the torque can reach 8445 N·m considering the loss, and the speed can reach 11.1 r / min, which can meet the use of the wire removal device.

[0048] As Figure 4 shown, the driving mechanism bracket 2 includes a driving bottom plate 21 fixed on the base 1. Two driving vertical frames 22 are fixed on the driving bottom plate 21. A number of driving mounting holes 221 are vertically distributed on the driving vertical frames 22. A driving channel steel 23 is installed on the driving vertical frames 22 through one of the driving mounting holes 221. A driving mounting plate 24 is installed between the two side driving channel steels 23. The driving motor 51 and the cycloid reducer 52 are installed on the driving mounting plate 24.

[0049] A number of driving mounting holes 221 with different heights are provided on the driving vertical frames 22, and the driving mounting plate 24 can be adjusted up and down within the stroke to match, so that the height of the driving mechanism 5 matches the height of the main shaft 7. The driving channel steel 23 is fixed on the driving vertical frames 22 by high-strength bolts, reducing the height difference between the driving mechanism 5 and the main shaft 7 and reducing the bending angle of the universal coupling 61. The adjustable height of the driving motor 51 is 500 - 1100 mm.

[0050] As Figure 6 shown, the transmission mechanism 6 includes a universal coupling 61. One end of the universal coupling 61 is connected to the output end of the driving mechanism 5, and the other end of the universal coupling 61 is connected to a transmission shaft 62. The transmission shaft 62 is rotatably connected to the transmission bracket 3, and the other end of the transmission shaft 62 is connected to the main shaft 7.

[0051] The universal coupling 61 selects a coupling with a shaft diameter of 100 mm and a length of 700 mm, and is connected to the output shaft of the main shaft 7 and the driving mechanism 5 through flange connectors at both ends. The transmission shaft 62 is processed from a 130 mm (negative tolerance) round steel with a length of 1200 mm. Its radial movement can be restricted by bearings and the base 1 bracket, and it can drive the main shaft 7. There is a flange at the end to connect main shafts 7 with different thicknesses and lengths. The bearings adopt models with an inner diameter matching the transmission shaft 62 of the main shaft 7. Here, SKF BB1-7009BB deep groove ball bearings scrapped from the maintenance of rail transit traction motors are used, and the bearing state meets the use requirements of the low-speed working conditions of the wire removal machine.

[0052] As Figure 5As shown in the figure, the transmission support 3 includes a transmission bottom plate 31 fixed to the base 1. A vertical frame 32 is fixed on the transmission bottom plate 31. Guide grooves 321 are provided on both sides inside the vertical frame 32. A bearing mounting seat 33 is sleeved between the guide grooves 321 on both sides. The transmission shaft 62 is installed in the bearing mounting seat 33 through bearings. A number of vertically distributed transmission mounting holes 322 are provided on the vertical frame 32. The bearing mounting seat 33 is installed on the vertical frame 32 through one of the transmission mounting holes 322.

[0053] The bearing mounting seat 33 reliably supports the transmission shaft 62 to ensure that the transmission shaft 62 is fixed to one side of the main shaft 7. Two sets of vertical frames 32 are arranged side by side, and channel steels welded to both sides of the main body frame are used as diagonal beams to enhance the overall rigidity of the frame and the main shaft 7, which can meet the one-side fixation of the main shaft 7. Transmission mounting holes 322 with different heights are provided on the vertical frame 32. The bearing mounting seat 33 can be adjusted in height up and down and is fixed through high-strength bolts at the determined-position transmission mounting holes 322. By adjusting the height of the transmission shaft 62, the height of the main shaft 7 is correspondingly adjusted to make the main shaft 7 adapt to the center heights of different motor stators 8. The adjustment range for the corresponding motor center height is 300 - 1300 mm. For motor stators 8 with lower center heights, the motor stator 8 can be padded to adapt to this wire stripping device.

[0054] An anchor nut 42 is fixed at the fixed anchor point 41. The fixed installation position of the motor stator 8 and the anchor nut 42 are connected by bolts. The steel plate platform 4 with the fixed anchor point 41 is composed of Q235 steel plates with a thickness of 20 mm and several anchor nuts 42. The positions of the anchor nuts 42 correspond to the fixed installation positions of the motor stator 8. As the anchor points for the installation of different motor stators 8, multiple anchor nuts 42 at different positions are pre-welded to adapt to more types of motor stators 8. The platform size is 2000 mm (radial) * 3000 mm (axial).

[0055] As Figure 7 and Figure 8 shown in the figure, the main shaft 7 is made of seamless steel pipe with an outer diameter of 102 mm and a wall thickness of 10 mm, and a length of 1000 mm. A flange is welded at the root for connection with the transmission shaft 62. A groove 71 with a width of 15 mm and a depth of 100 mm is machined at the end, which can quickly disassemble and assemble the wire rope 9.

[0056] The wire rope 9 is selected as a finished 10 mm interwoven wire sling. A single-side ring 92 is left. The side of the ring 92 needs to be stuck into the groove 71 of the main shaft 7. A clamping plate 91 is installed on the other side. The overall length needs to be greater than the core radius of the motor stator 8 to be disassembled. The structure of the clamping plate 91 is flexible, but it is necessary to ensure that there are no less than 3 holes on the clamping plate 91 with a diameter larger than the diameter of the wire rope 9 for threading the wire rope 9. After the wire rope 9 passes through the clamping plate 91, it fixes the coil 81 of the motor stator 8 to be disassembled. The ring 92 on the wire rope 9 can pass through two grooves 71 and be sleeved with the main shaft 7, and the rope buckle 93 can be connected to the nose of the coil 81.

[0057] The pallet 91 is provided with at least three rope holes, and the winding rope 9 passes through all the rope holes in sequence; the winding rope 9 first passes out of the side of the pallet 91 away from the main shaft 7 and then passes back into the pallet 91, leaving a rope loop 93. After the winding rope 9 passes through a number of rope holes on the pallet 91 in sequence, the end of the winding rope 9 can form a rope loop 93. The rope loop 93 can be hung on the nose of the coil 81 to ensure that the winding rope 9 can pull the coil 81. When the winding rope 9 is pulled, the winding rope 9 is locked with at least three rope holes on the pallet 91 to prevent the rope loop 93 from being disengaged from the pallet 91, and the rope loop 93 is reliably connected to the nose of the coil 81.

[0058] The method for removing the stator winding of a single-output-shaft motor in this embodiment includes the following steps:

[0059] S1: According to the center height of the motor stator 8, adjust the height of the main shaft 7 and the height of the driving mechanism 5 to appropriate positions; turn on the main switch of the electric control cabinet;

[0060] S2: Lift the motor stator 8 through the main shaft 7 and place it on the steel plate platform 4;

[0061] S3: Fix the motor stator 8 to the steel plate platform 4 using bolts or high-strength polyester binding straps, and different fixing methods can be used for different motors;

[0062] S4: Pass the ring 92 of the winding rope 9 through two clamping grooves 71 and then sleeved on the main shaft 7, and connect the nose of the coil 81 to the winding rope 9 through the rope loop 93;

[0063] S5: The driving mechanism 5 drives the main shaft 7 to rotate through the transmission mechanism 6, the main shaft 7 winds and tightens the winding rope 9 to the main shaft 7, and the winding rope 9 pulls the coil 81 out of the iron core slot of the motor stator 8;

[0064] S6: When the coil 81 is completely pulled out of the motor stator 8, stop the rotation of the main shaft 7 in time and reverse the main shaft 7 by an appropriate number of turns to facilitate the removal of the ring 92;

[0065] S7: Remove the ring 92 from the main shaft 7, pull the winding rope 9, and pull out the coil 81 through the winding rope 9;

[0066] S8: Repeat steps S4 to S7 until all the coils 81 are pulled out;

[0067] S9: Remove the motor stator 8 from the fixed anchor point 41 of the steel plate platform 4 and lift the motor stator 8 away.

[0068] The present invention adopts a main shaft 7 in a single-output-shaft form, which makes the installation and disassembly of the electronic stator of the wire removal device convenient and shortens the preparation time. The end of the main shaft 7 is provided with clamping grooves 71 to fix the winding rope 9, and in combination with the single-output-shaft form, the removal of the waste wire after each group of wire removal becomes very fast, and the wire removal time can be shortened from 6 hours to 1 hour.

[0069] The present invention is not limited to the above optional embodiments, and any person can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they are all within the protection scope of the present invention.
