Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of motor stator core installation equipment, and particularly relates to a generator stator core installation structure. Background Technology
[0002] The stator core is the main magnetic circuit of the stator and also serves as the mounting and fixing component for the stator windings. The stator core consists of components such as sector-shaped laminations, ventilation slots, toothed pressure plates, tension bolts, support blocks, and positioning ribs. Due to its weight, it requires hoisting equipment for installation.
[0003] During hoisting, the ropes need to be wrapped around the outside before hoisting. When using rope binding, the stator needs to be lifted before wrapping, which makes the conventional stator installation operation quite troublesome.
[0004] To address this issue, we propose a generator stator core mounting structure. Utility Model Content
[0005] The purpose of this utility model is to solve the problem of the cumbersome installation operation of conventional stator cores, and to propose a generator stator core installation structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A generator stator core mounting structure includes a stator core, with three spring clips evenly arranged inside the stator core. A guide seat is fixedly connected to the upper end of each spring clip, and a lock cylinder is slidably installed inside the guide seat. A pull button is fixedly connected to the upper end of the lock cylinder, and a lifting ring is rotatably connected to the upper part of the guide seat. The lifting ring is in movable contact with the pull button, and the lock cylinder is placed on the lower inner wall of the spring clip. Turn the lifting ring to the side to remove obstruction at the top of the pull button. Pull the pull button upwards, causing it to act upwards on the lock cylinder, which then rises. This causes the spring clip to retract inwards due to its elasticity. Insert the spring clip into the stator core and press the pull button downwards, causing it to move the lock cylinder back to its original position. The lock cylinder then pushes the spring clip outwards, causing it to open and latch onto the lower part of the stator core. Next, raise the lifting ring and hook it onto the lifting hook. When the hook acts upwards on the lifting ring, the lifting ring acts upwards on the guide seat, which in turn acts upwards on the spring clip, causing the spring clip to act upwards on the stator core, facilitating the lifting of the stator core.
[0008] Preferably, the guide seat includes a base body and a bearing seat, with the bearing seat symmetrically and fixedly connected to the base body. The bearing seat facilitates the rotatable connection between the guide seat and the lifting ring.
[0009] Preferably, the lifting ring includes a swing plate, a ring body, and a rotating shaft. The lower end of the ring body is fixedly connected to the upper end of the swing plate, and the rotating shaft is symmetrically fixedly connected to the lower end of the swing plate. During the lifting process, the hook acts upward on the ring body, causing the ring body to act upward on the swing plate, keeping the swing plate upright and preventing the lock cylinder from rising, thus ensuring the stability of the lock cylinder's locked state.
[0010] Preferably, the lock cylinder includes a push-pull column and a lock disc, with the lower end of the push-pull column fixedly connected to the upper end of the lock disc. The lock disc, positioned under the spring clip, prevents the spring clip from retracting during hoisting, thus improving the safety of the hoisting operation.
[0011] Preferably, the upper end of the lock disc has a through hole. The through hole reduces the load on the lock cylinder.
[0012] Preferably, the pull button includes a pull button body and a connecting post, with the lower end of the pull button body fixedly connected to the upper end of the connecting post. Squeezing the pull button body upwards and pulling it causes the pull button body to act upwards on the connecting post, which in turn acts upwards on the push-pull post, facilitating the upward pulling of the lock cylinder.
[0013] Preferably, the pull button further includes an arc-shaped top plate, the lower end of which is fixedly connected to the upper end of the pull button body. The arc-shaped top plate, placed between the pull button body and the swing plate, further increases the stability of the lock cylinder position.
[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] 1. Turn the lifting ring to the side to remove obstruction at the top of the pull button. Pull the pull button upwards, causing it to act upwards on the lock cylinder, which in turn raises the cylinder. This causes the spring clip to retract inwards due to its elasticity. Insert the spring clip into the stator core and press the pull button downwards, causing it to move the lock cylinder back to its original position. The lock cylinder then pushes the spring clip outwards, causing it to open and latch onto the lower part of the stator core. Next, raise the lifting ring and hook the hook onto it. When the hook acts upwards on the lifting ring, the lifting ring acts upwards on the guide seat, which in turn acts upwards on the spring clip, causing the spring clip to act upwards on the stator core, facilitating the lifting of the stator core.
[0016] 2. During the hoisting process, the hook acts upward on the ring body, which in turn acts upward on the swing plate, keeping the swing plate upright and preventing the lock cylinder from rising, thus ensuring the stability of the lock cylinder's locked state.
[0017] 3. Use a locking disc pad under the spring clip to prevent the spring clip from retracting during hoisting, thereby improving the safety of hoisting operations.
[0018] 4. Squeeze the button body upwards and pull it up. The upward action of the button body acts on the connecting pin, which in turn acts on the push-pull pin, making it easy to pull the lock cylinder upwards. Attached Figure Description

[0025] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.
[0026] Reference Figure 1 A generator stator core mounting structure includes a stator core 1. The stator core 1 has three spring clips 6 that are evenly distributed inside. The upper end of the spring clip 6 is fixedly connected to a guide seat 2. The guide seat 2 has a lock cylinder 4 that is slidably installed inside. The upper end of the lock cylinder 4 is fixedly connected to a pull button 5. The upper part of the guide seat 2 is rotatably connected to a lifting ring 3. The lifting ring 3 is in contact with the pull button 5. The lock cylinder 4 is placed on the lower inner wall of the spring clip 6.
[0027] Reference Figure 1 and 2 The guide seat 2 includes a seat body 21 and a bearing seat 22, with the bearing seat 22 symmetrically and fixedly connected to the seat body 21. The bearing seat 22 is used for rotatably mounting the lifting ring 3.
[0028] Reference Figure 1 , 2 3. The lifting ring 3 includes a swing plate 31, a ring body 32, and a rotating shaft 33. The rotating shaft 33 is rotatably mounted in the bearing seat 22. The lower end of the ring body 32 is fixedly connected to the upper end of the swing plate 31, and the rotating shaft 33 is symmetrically fixedly connected to the lower end of the swing plate 31. During the lifting process, the hook acts upward on the ring body 32, causing the ring body 32 to act upward on the swing plate 31, keeping the swing plate 31 upright and preventing the lock cylinder 4 from rising upward.
[0029] Reference Figure 1 , 2 4. The lock cylinder 4 includes a push-pull column 41 and a lock disc 42. The push-pull column 41 slides through the base 21, and the lock disc 42 is placed under the spring clip 6. The lower end of the push-pull column 41 is fixedly connected to the upper end of the lock disc 42. The lock disc 42 is used to place under the spring clip 6 to prevent the spring clip 6 from retracting during hoisting.
[0030] Reference Figure 1 and 4 The upper end of the lock disc 42 has a through hole 43. The through hole 43 reduces the load on the lock cylinder 4.
[0031] Reference Figure 1 , 2 4 and 5, the pull button 5 includes a pull button body 51 and a connecting post 53. The lower end of the connecting post 53 is fixedly connected to the upper end of the push-pull post 41, and the lower end of the connecting post 53 is in movable contact with the base 21. The lower end of the pull button body 51 is fixedly connected to the upper end of the connecting post 53. When the pull button body 51 is squeezed and pulled upward, the pull button body 51 acts upward on the connecting post 53, which in turn acts upward on the push-pull post 41.
[0032] Reference Figure 1 , 3 In addition to the pull button 5, the pull button 5 also includes an arc-shaped top plate 52. The upper part of the arc-shaped top plate 52 is in contact with the swing plate 31, and the lower end of the arc-shaped top plate 52 is fixedly connected to the upper end of the pull button body 51. By using the arc-shaped top plate 52 between the pull button body 51 and the swing plate 31, the stability of the lock cylinder 4 position is further increased.
[0033] Working principle: Turn the lifting ring 3 to the side to remove the obstruction at the upper end of the pull button 5. Pull the pull button 5 upward, causing it to act upward on the lock cylinder 4, which in turn raises the lock cylinder 4. This causes the spring clip 6 to retract inward due to its elastic force. Insert the spring clip 6 into the stator core 1. Press the pull button 5 downward, causing it to move the lock cylinder 4 back to its original position. The lock cylinder 4 then pushes the spring clip 6 outward, causing it to open and latch onto the lower part of the stator core 1. Then, raise the lifting ring 3 and hang the hook on it. When the hook acts upward on the lifting ring 3, it acts upward on the guide seat 2, which in turn acts upward on the spring clip 6, which in turn acts upward on the stator core 1, facilitating the lifting of the stator core 1.
