Description

Technical Field

[0001] The utility model relates to the technical field of motor anti-vibration, in particular to a high-power asynchronous motor with an anti-vibration structure. Background Art

[0002] The motor is mainly composed of a stator and a rotor. The direction of the force on the current-carrying wire in the magnetic field is related to the direction of the current and the magnetic flux lines (magnetic field direction). The motor uses the energized coil (that is, the stator winding) to generate a rotating magnetic field and act on the rotor. This forms a magnetic electromotive force rotation torque. It converts electrical energy into mechanical energy. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors.

[0003] The patent document with publication number CN219960284U discloses an AC motor with a seismic-resistant structure. By installing the seismic-resistant structure on the AC motor body, when the AC motor body vibrates after operation, the vibration in the horizontal direction can be weakened by the horizontal shock-absorbing airbag, and the vibration in the vertical direction can be weakened by the damper, thereby reducing damage to the motor itself.

[0004] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0005] Existing AC motors with anti-seismic structures can reduce the vibration generated during the operation of the motor in both horizontal and vertical directions through shock-absorbing airbags and dampers. However, in actual use, since the anti-seismic structural components of the motor are large in size, a larger mounting plate is required. During the matching use, the size of the motor is easily increased, which increases the difficulty of motor assembly and use. Utility Model Content

[0006] In order to overcome the problem that the existing AC motor with a seismic structure reduces the vibration generated during the operation of the motor in the horizontal and vertical directions through the shock-absorbing airbags and dampers on the seismic structure, it is easy to use a larger mounting plate due to the large size of the seismic structure device matched with the motor. During the matching use, it is easy to increase the size of the motor, which increases the difficulty of assembling and using the motor. The embodiment of the present application provides a high-power asynchronous motor with a seismic structure. The seismic structure is installed between the bottoms of two motor chassis by using a base, so that the bottom of the support member on the seismic structure protrudes from the bottom surface of the motor chassis. After the motor body is installed to the target position, the supporting horizontal plate on the supporting member contacts the target position, so that the bottom of the supporting horizontal plate is compressed, so that the supporting vertical plate applies pressure to the two supporting bottom plates toward the top, and with the help of the two second inclined surfaces on the supporting vertical plate and the first inclined surfaces on the two supporting bottom plates, the two supporting bottom plates are pushed away from each other, so that the pressure is transmitted to the damper, so that the vibration generated during the operation of the motor body is reduced by the damper, which can not only achieve the effect of stable seismic resistance, but also the overall footprint of the bottom of the motor body is small, and the problem of increased difficulty in motor installation will not occur.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] A high-power asynchronous motor with an anti-seismic structure comprises a motor body and an anti-seismic structure, wherein the anti-seismic structure is arranged at the bottom of the motor body;

[0009] Among them, motor base frames are processed on both sides of the bottom of the motor body, the seismic anti-vibration structure includes a support member, a base is arranged on the top of the support member, the support member includes a supporting cross plate, a supporting vertical plate is integrally formed at the center of the top of the supporting cross plate, two left-right symmetrical supporting bottom plates are arranged at the center of the bottom of the base, dampers are arranged at both ends of one side of the supporting bottom plate, second inclined surfaces are processed on both sides of the top of the supporting vertical plate, and a first inclined surface is processed on the other side of the supporting bottom plate.

[0010] In a possible implementation, the two motor frames are symmetrically arranged on the left and right, and both ends of the base are fixed to the inner sides of the two motor frames and their bottoms by bolts. The bolts pass from the bottom of the motor frame to the top, and the heads are retracted and connected to the inside of the base.

[0011] In a possible implementation, first sliding rods are processed on surfaces at both ends of one side of the two supporting base plates, the two first sliding rods are located between two dampers on the same side, and the first sliding rods are slidably connected to the inside of the base.

[0012] In a possible implementation, one end of the two dampers on one side is hingedly connected to a surface of one side of a supporting base plate, and the other end of the two dampers on one side is hingedly connected to an inner wall of one end of the base.

[0013] In a possible implementation, the two second inclined surfaces are matched with the two first inclined surfaces, and the bottom of the supporting cross plate is pressurized, so that the supporting vertical plate applies pressure to the two supporting bottom plates toward the top, and the two supporting bottom plates are pushed away from each other by means of the two second inclined surfaces on the supporting vertical plates and the first inclined surfaces on the two supporting bottom plates.

[0014] In a possible implementation, second sliding bars are processed on the tops of both ends of the supporting vertical plates, and the second sliding bars are slidably connected to the inside of the base.

[0015] In a possible implementation, a threaded rod is processed at the center of the top of the supporting vertical plate, one end of the threaded rod is threadedly connected with an adjusting nut and a locking nut, the adjusting nut is located between the threaded rod and the base, and the threaded rod is slidably connected to the inside of the base.

[0016] In summary, the present invention includes at least one of the following beneficial technical effects:

[0017] 1. The anti-seismic structure is installed between the bottoms of the two motor chassis by using the base, so that the bottom of the support member on the anti-seismic structure protrudes from the bottom surface of the motor chassis. After the motor body is installed to the target position, the support horizontal plate on the support member contacts the target position, so that the bottom of the support horizontal plate is compressed, so that the support vertical plate applies pressure to the two support bottom plates toward the top, and the two second inclined surfaces on the support vertical plate and the first inclined surfaces on the two support bottom plates are used to push the two support bottom plates away from each other, so that the pressure is transmitted to the damper, so that the vibration generated during the working process of the motor body is reduced by the damper, which can not only achieve a stable anti-seismic effect, but also the overall footprint of the bottom of the motor body is small, and the problem of increased difficulty in motor installation will not occur;

[0018] 2. By processing a threaded rod at the center of the top of the supporting vertical plate and processing a second sliding rod at the top of both ends, when the threaded connection between the adjusting nut and one end of the threaded rod is adjusted, the unpressurized state of the bottom of the supporting member can be adjusted, and the distance that the bottom of the supporting cross plate on the supporting member protrudes from the bottom surface of the motor frame can be controlled, so as to control the support member to push the two supporting bottom plates away from each other and compress the damper to facilitate the control of the vibration reduction ability of the four dampers.

DETAILED DESCRIPTION

[0024] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0025] Embodiment 1:

[0026] This embodiment introduces a specific structure of a high-power asynchronous motor with a seismic-resistant structure. Figure 1-Figure 4 As shown, it includes 1 and an anti-seismic structure 3 arranged at the bottom of the motor body 1, both sides of the bottom of the motor body 1 are processed with a motor chassis 2, the anti-seismic structure 3 includes a support member 301, and a base 302 is arranged on the top of the support member 301;

[0027] like Figure 4 As shown, the support member 301 includes a support horizontal plate 3012, a support vertical plate 3011 is integrally formed at the center of the top of the support horizontal plate 3012, two left-right symmetrical support bottom plates 309 are arranged at the center of the bottom of the base 302, dampers 303 are arranged at both ends of one side of the support bottom plate 309, second inclined surfaces 5 are processed on both sides of the top of the support vertical plate 3011, and a first inclined surface 4 is processed on the other side of the support bottom plate 309;

[0028] The two motor base frames 2 are arranged symmetrically on the left and right. Bolts are passed through the bottom of the motor base frames 2 to the top, so that the base 302 is fixed to the bottom of the two motor base frames 2 from the inner side thereof, and the heads of the bolts are ensured to be received inside the base 302. During the installation of the motor body 1, the anti-seismic structure 3 is received between the two motor base frames 2, and there will not be too many parts at the bottom of the motor body 1, resulting in a larger overall volume.

[0029] Secondly, if Figure 2 and Figure 4As shown, one end of the two dampers 303 on one side is hingedly connected to the surface of one side of a supporting base plate 309, and the other end of the two dampers 303 on one side is hingedly connected to the inner wall of one end of the base 302, so that the two dampers 303 on one side can be compressed in the horizontal plane, such as Figures 2 to 4 As shown, the surfaces of both ends of one side of the two support bottom plates 309 are processed with first slide bars 304. By making the two first slide bars 304 located between the two dampers 303 on the same side and being able to slide inside the base 302, the movable path at the bottom of the base 302 can be controlled, so that the damper 303 is compressed in the horizontal plane;

[0030] Furthermore, the two second inclined surfaces 5 are matched with the two first inclined surfaces 4. When the motor body 1 is installed to the target position through the two motor base frames 2, the supporting cross plate 3012 on the supporting member 301 contacts the target position, so that the bottom of the supporting cross plate 3012 is compressed, so that the supporting vertical plate 3011 applies pressure to the two supporting bottom plates 309 toward the top, and with the help of the two second inclined surfaces 5 on the supporting vertical plate 3011 and the first inclined surfaces 4 on the two supporting bottom plates 309, the two supporting bottom plates 309 are pushed away from each other, so that the pressure is transmitted to the damper 303. When the motor body 1 vibrates during operation, the displacement generated by the vibration is transmitted to the supporting bottom plate 309 through the supporting member 301, and is received by the two dampers 303 between one end of the base 302 and one side of the supporting bottom plate 309, and is finally absorbed inside the damper 303 to reduce the vibration.

[0031] By adopting the above technical solution:

[0032] The above design uses the base 302 to install the earthquake-resistant structure 3 between the bottoms of the two motor chassis 2, so that the bottom of the support member 301 on the earthquake-resistant structure 3 protrudes from the bottom surface of the motor chassis 2. After the motor body 1 is installed to the target position, the support cross plate 3012 on the support member 301 contacts the target position, so that the bottom of the support cross plate 3012 is compressed, so that the support vertical plate 3011 applies pressure to the two support bottom plates 309 toward the top, and the two second inclined surfaces 5 on the support vertical plate 3011 and the first inclined surfaces 4 on the two support bottom plates 309 are used to push the two support bottom plates 309 away from each other, thereby transmitting the pressure to the damper 303, so that the damper 303 is in a contracted state in the initial state;

[0033] When the motor body 1 generates vibration during operation, the displacement generated by the vibration is transmitted to the supporting base plate 309 through the supporting member 301, and is received by the two dampers 303 between one end of the base 302 and one side of the supporting base plate 309. The damper 303 resets after being compressed to reduce the vibration, which is convenient for absorption inside the damper 303.

[0034] Embodiment 2:

[0035] Based on Example 1, this example introduces the specific structure of the support member 301. The tops of both ends of the support vertical plate 3011 are processed with second sliding rods 305. The center of the top of the support vertical plate 3011 is processed with a threaded rod 308. One end of the threaded rod 308 is threadedly connected with an adjusting nut 307 and a locking nut 306. 308 is slidably connected to the inside of the base 302.

[0036] By making the second sliding rod 305 slidably connected to the inside of the base 302, the path of the support member 301 moving toward the top can be controlled, thereby pushing the two support bottom plates 309 away from each other from the center to both sides;

[0037] Secondly, by adjusting the threaded connection between the adjusting nut 307 and one end of the threaded rod 308, the distance of the bottom of the supporting cross plate 3012 on the supporting member 301 protruding from the bottom surface of the motor chassis 2 can be controlled when the bottom of the supporting member 301 is not under pressure, so as to facilitate the control of the ability of the four dampers 303 to reduce vibration;

[0038] At the same time, the adjusting nut 307 is located between the threaded rod 308 and the base 302. By adjusting the threaded connection between the locking nut 306 and one end of the threaded rod 308 and applying pressure to the surface of the adjusting nut 307, the adjusting nut 307 can be restricted from rotating outside the threaded rod 308 without external force.

[0039] By adopting the above technical solution:

[0040] The above design processes a threaded rod 308 at the center of the top of the supporting vertical plate 3011, and processes a second sliding rod 305 at the top of both ends of 3011. When the threaded connection between the adjusting nut 307 and one end of the threaded rod 308 is adjusted, the bottom of the supporting member 301 is adjusted to be in an unpressurized state. The distance of the bottom of the supporting horizontal plate 3012 on the supporting member 301 protruding from the bottom surface of the motor chassis 2 can be controlled to control the support member 301 to push the two supporting bottom plates 309 away from each other, and to compress the damper 303, so as to facilitate the control of the ability of the four dampers 303 to reduce vibration.

[0041] At the same time, by adjusting the threaded connection between the locking nut 306 and one end of the threaded rod 308, the locking nut 306 applies pressure to the surface of the adjusting nut 307, which can limit the adjusting nut 307 from rotating outside the threaded rod 308 without external force, thereby ensuring the stability of the adjusting nut 307 when there is no contact with the bottom of the threaded rod 308.

[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
