Description

Technical Field

[0001] The utility model relates to the technical field of motor rotors, in particular to a maintenance extraction tool for motor rotors. Background Art

[0002] The rotor is an important mechanical structure in the motor and is widely used in various motor devices. Its basic working principle is to convert or transfer energy through rotational motion. In different application scenarios, the working principle of the rotor may vary, but its core mechanism is usually the same.

[0003] When the existing device is under maintenance, it is difficult to keep the front and rear shafts horizontal during hoisting, and the stator core and winding may be damaged during the extraction process. When rotor extraction and maintenance operations are required, the only electric hoist cannot extract the rotor, and the installation and disassembly are inconvenient. Summary of the Utility Model

[0004] The utility model discloses a maintenance extraction tool for motor rotors, aiming to solve the technical problems of difficult installation and disassembly of the electronic rotor, easy damage to the stator core and winding in the motor during the removal process, and complication of the motor rotor extraction operation.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A maintenance extraction tool for motor rotors includes a gantry. A clamping device is arranged below the top of the gantry. The clamping device includes a wheel disc, and a plurality of first chutes are opened in the wheel disc. Sliding seats are movably connected in the first chutes. Arc-shaped plates are fixedly connected to the front sides of the sliding seats. A servo motor three is arranged at the rear side of the wheel disc. The output shaft of the servo motor three is fixedly connected with a rotating disc, and the rotating disc is movably connected between the front side of the rotating disc and the rear side of the wheel disc. The rear sides of the sliding seats are movably connected with rotating rods, and the rotating rods are movably connected between the front side of the rotating rods and the rear side of the rotating disc. Connecting shafts three are fixedly connected to the rear sides of the symmetric sliding seats. Fixed frames three are fixedly connected to the front sides of the connecting shafts three, and a telescopic shaft is fixedly connected between the symmetric fixed frames three.

[0007] By providing a gantry, a clamping device, an arc-shaped plate, a sliding seat, a connecting shaft III, a wheel disc, a rotating disc, a fixing frame III, a servo motor III, a rotating rod and a telescopic shaft, when disassembling the rotor on the motor, start the servo motor III to drive the rotating disc to rotate. At the same time, the rotating rod connected to the rotating disc drives the sliding seat to reciprocate in the chute I on the wheel disc, so that the arc-shaped plate clamps the rotor. When the arc-shaped plate exerts a clamping effect, the fixing frame III on the connecting shaft III connected to the sliding seat performs a telescopic movement on the telescopic shaft. During this process, the clamping device firmly clamps the motor rotor, effectively preventing the rotor from falling during extraction and damaging the stator core and winding. The clamping method is more effective for installing and disassembling the motor rotor, reducing the occupation of hoisting worker resources.

[0008] In a preferred solution, a support frame I is fixedly connected to the lower side of the top of the gantry, and a chute II is provided on the support frame I. A sliding mechanism is arranged inside the chute II. The sliding mechanism is located above the clamping device. The sliding mechanism includes two symmetric pulleys. A connecting shaft II is fixedly connected between the symmetric pulleys. The outer parts of the connecting shafts II are movably connected with belts. In front of the pulleys in the sliding mechanism, there is a servo motor II. The output shaft of the servo motor II is fixedly connected to the front side of the pulley. Connecting shafts I are fixedly connected to both sides of the connecting shaft II. L-shaped plates are fixedly connected to the front sides of the connecting shafts I and the front side of the servo motor II.

[0009] By providing a support frame I, a sliding mechanism, pulleys, a servo motor II, L-shaped plates, belts, connecting shafts I and connecting shafts II, when transporting the motor rotor, the sliding mechanism moves in the chute II on the support frame I. When moving, start the servo motor II to drive the pulleys to rotate, so that while displacing on the support frame, the belt fixes the connecting shaft II connected to the pulley. The connecting shafts I and L-shaped plates connected to the connecting shaft II are displaced under the action of the servo motor II. During this process, the sliding mechanism is beneficial for transporting and storing the motor rotor, avoiding accidents and damage. This mechanism is simple to use and maintain, and the probability of problems is small.

[0010] In a preferred embodiment, support columns are fixedly connected to the lower sides of the L-shaped plates. The lower sides of the support columns are fixedly connected to base plates I. Symmetrical fixing frames I are fixedly connected to the upper sides of the base plates I. Moreover, a base frame I is fixedly connected to the upper side of the base plate I. The base frame I is located behind the fixing frames I. A servo motor I is fixedly connected to the upper side of the base frame I. A hole is formed in the fixing frame I. The output shaft of the servo motor I passes through the hole and is fixedly connected to a rotating shaft. A plurality of layers of steel cable ropes are wound around the outer side of the rotating shaft. A plurality of layers of telescopic rods are fixedly connected to the lower side of the base plate I. Two fixing frames II are fixedly connected to the outer sides of the plurality of layers of telescopic rods. Through holes are formed in the fixing frames II. The head of the steel cable rope passes through the through hole and is fixedly connected to a fixing shaft. Moreover, a fixed connection is formed between the upper side of the fixing shaft and the lower side of the plurality of layers of telescopic rods. A chassis is fixedly connected to the lower side of the fixing shaft. The clamping device is located in front of the plurality of layers of telescopic rods. A base plate II is fixedly connected to the lower side of the chassis. A support frame II is fixedly connected to the upper side of the base plate II. Moreover, a fixed connection is formed between the front side of the support frame II and the rear side of the wheel disc. A base frame II is fixedly connected to the upper side of the base plate II. Moreover, a fixed connection is formed between the front side of the base frame II and the lower side of the wheel disc.

[0011] By providing the support columns, base plates I, fixing frames I, rotating shafts, steel cable ropes, servo motor I, base frames I, a plurality of layers of telescopic rods, fixing frames II, fixing shafts and chassis, when lifting and lowering the clamping device, by starting the servo motor I to release the steel cable ropes wound around the rotating shaft, and at the same time, the plurality of layers of telescopic rods fixedly connected to the heads of the steel cable ropes descend, so as to adjust the clamping device to in front of the motor rotor. During this process, the lifting and lowering of the plurality of layers of telescopic rods effectively adapt to motor devices of different heights, which is more convenient for the installation and disassembly of the motor rotor and improves the maintenance efficiency.

[0012] As can be seen from the above, a motor rotor maintenance extraction tool provided by the present invention has the technical effects of clamping and fastening the motor rotor through the clamping device, effectively preventing the rotor from falling during the extraction process and damaging the stator core and windings, adopting the clamping method to more effectively install and disassemble the motor rotor, and reducing the occupation of hoisting resources.
