Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly equipment, and particularly relates to a disassembly and assembly structure for an exciter stator. Background Art

[0002] An exciter is a motor that converts electrical energy into magnetic field energy and can be used in equipment such as power systems, motors, and magnets. Excitation is the process of providing a working magnetic field for electrical equipment operating on the principle of electromagnetic induction, and an exciter is a device that provides electrical energy for excitation. The exciter stator is a part of the generator and is the component that generates the magnetic field. The working principle of the exciter is understood through the structure of the induction exciter. The stator core is made of silicon steel sheets, with large slots inside for placing the excitation winding and small slots for placing the armature winding. The rotor is laminated from silicon steel sheets with a toothed cross-section to form a basic power generation structure.

[0003] In the existing disassembly and assembly structure for an exciter stator, during the process of placing the stator inside the motor, due to the large volume of the stator itself, during the movement process, it is mostly carried by a movable trolley or a sliding table structure until the stator is transported to a position directly opposite the motor, and then the installation and disassembly operations are carried out. When the stator is moved from the trolley or the sliding table structure into the motor, the stator is prone to friction with the above structures, forming frictional resistance, reducing the moving speed of the stator, and also easily causing frictional damage to the stator, affecting the orderly implementation of the stator disassembly and assembly work. Summary of the Utility Model

[0004] In view of the above problems, the present application provides a disassembly and assembly structure for an exciter stator.

The support rollers and the conveying rollers can carry the stator. During the installation process of the stator, the stator moves along the distribution direction of the support rollers, and the conveying rollers can roll along the moving direction of the stator.

[0006] Further, the two left and right distributed conveying rollers are connected by a connecting rod, and multiple connecting rods distributed from front to back are connected by an adapter rod. Both ends of the adapter rod are provided with support feet, and driving cylinders I for controlling their lift and lower movements are arranged on the support feet.

[0007] Further, the bottom end of the carrier seat is connected with a linkage seat through an adapter plate, and the driving cylinders I are all arranged in the gap between the carrier seat and the linkage seat.

[0008] Further, a pair of rotatable alignment arms and a driving motor for controlling the rotation of the alignment arms are provided on the connecting plate. The top ends of the alignment arms are directly above the carrier seats, and driving cylinders II are provided on the carrier seats. The output ends of the driving cylinders II are provided with top contact joints. When the top contact joints move, the stator located on the conveying rollers can move along the distribution direction of the conveying rollers.

[0009] Further, bases parallel to the linkage seats are provided below the linkage seats, and a lead screw slide table for driving the linkage seats to move linearly is provided on the bases.

[0010] Further, guide rails are provided on the bases, and guide seats adapted to the guide rails are provided at the bottoms of the linkage seats.

[0011] Further, rotating shafts coaxially distributed with the supporting rollers are provided on the supporting rollers, and inclined extension positioning frames are provided on the rotating shafts. The inclined extension positioning frames are all arranged on the carrier seats.

[0012] In summary, the technical effects and advantages of the present utility model are as follows:

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment: Refer to Figures 1-4 A disassembly and assembly structure for an exciter stator shown in the figure, including a movable bearing seat 1. Two parallelly distributed support rollers 4 are provided on the bearing seat 1. Two groups of conveying rollers 7 capable of ascending and descending movements are provided in the relative space between the two support rollers 4. The support rollers 4 and the conveying rollers 7 can carry the stator, and as the bearing seat 1 moves, the stator can be transported to a designated position.

[0022] During the transportation of the stator, the support rollers 4 can prevent the stator from slipping off the bearing seat 1. When the stator moves to the designated position along with the bearing seat 1, the conveying rollers 7 can be controlled to rise until the stator is away from the support rollers 4. Subsequently, the stator can be controlled to move along the distribution direction of the support rollers 4. During this process, the conveying rollers 7 can roll along the moving direction of the stator until the stator enters the motor to complete the installation operation.

[0023] As Figure 3 、 Figure 4 shown, the two conveying rollers 7 distributed on the left and right are connected by a connecting rod 8. A plurality of connecting rods 8 distributed from front to back are connected by a connecting bar 9. Support legs 10 are provided at both ends of the connecting bar 9. First driving cylinders 11 capable of controlling their ascending and descending movements are provided on the support legs 10. When the support legs 10, the connecting bar 9, the connecting rods 8 and the conveying rollers 7 rise synchronously, the stator can be away from the support rollers 4. During the rising process of the stator, the friction resistance between itself and the support rollers 4 can be avoided, which has a protective effect on the surface of the stator. Moreover, during the moving process of the stator, the conveying rollers 7 can roll along the moving direction of the stator, improving the smoothness of the stator during the moving process.

[0024] As Figure 1 、 Figure 2As shown in the figure, the bottom end of the bearing seat 1 is connected to a linkage seat 3 through an adapter plate 2. Under the connection of the adapter plate 2, the linkage seat 3 can move synchronously with the bearing seat 1. To maintain the stability of the first driving cylinder 11, the first driving cylinders 11 are all arranged in the gap between the bearing seat 1 and the linkage seat 3.

[0025] As Figure 1 , Figure 2 shown in the figure, a pair of rotatable alignment arms 12 and a driving motor 15 for controlling the rotation of the alignment arms 12 are provided on the adapter plate 2. When the stator moves away from the support roller 4 as the conveying roller 7 rises, the driving motor 15 can control the rotation of the positioning arm 12 until the top end of the alignment arm 12 approaches the stator.

[0026] The top end of the alignment arm 12 is directly above the bearing seat 1, and second driving cylinders 13 are provided on the bearing seat 1. A top contact joint 14 is provided at the output end of each second driving cylinder 13. When the top contact joint 14 moves, the stator located on the conveying roller 7 can move along the distribution direction of the conveying roller 7. Until the stator is moved into the motor, the installation operation of the stator is completed.

[0027] In this process, the time required for the manual movement process is reduced, the moving speed and stability of the stator are improved. During the installation process of the stator, the stator can be quickly and accurately moved into the motor, improving the work efficiency during the stator installation operation.

[0028] As Figure 1 shown in the figure, bases 16 parallel to the linkage seat 3 are provided below the linkage seat 3, and a lead screw slide table 17 for driving the linear movement of the linkage seat 3 is provided on the bases 16. During operation, the lead screw slide table 17 can drive the stator to move synchronously to achieve the purpose of transferring the stator until the stator is transferred to the designated destination.

[0029] As Figure 2 shown in the figure, in order to maintain the linearity of the movement of the linkage seat 3 and avoid shaking of the linkage seat 3, the bearing seat 1 and the stator during movement. A guide rail 18 is provided on the base 16, and guide seats 19 adapted to the guide rail 18 are provided at the bottom of the linkage seat 3. Further improving the accuracy during the stator installation and disassembly work process.

[0030] As Figure 2 shown in the figure, in order to maintain the stability of the support roller 4 and ensure the load-bearing capacity of the support roller 4, rotating shafts 5 coaxially distributed with the support roller 4 are provided on the support roller 4, and inclined extension positioning frames 6 are provided on the rotating shafts 5, and the inclined extension positioning frames 6 are all arranged on the bearing seat 1.
