Device for installing stator bar on stator base

Abstract

The utility model provides a device for installing a stator bar on a stator frame, which comprises a fixing mechanism and a rotating mechanism, and a hoisting mechanism for hoisting the stator bar is arranged on the rotating mechanism in a selective mode. Wherein the fixing mechanism is arranged in the diameter direction of the top-layer annular plate, the fixing mechanism and the top-layer annular plate are relatively fixed together, one end of the rotating mechanism is located in the cavity, and the other end of the rotating mechanism extends to the middle of the fixing mechanism and is connected with the fixing mechanism in a rotating mode so that the rotating mechanism can rotate in the cavity in the circumferential direction around the fixing mechanism. In the arrangement mode, the stator bar hoisted by the hoisting mechanism can rotate circumferentially in the cavity. Therefore, the circumferential installation of the stator bar can be realized by arranging the hoisting mechanism once. Through the mode, the working procedures of frequently replacing a hoisting point and re-suspending the hoisting hoist in the prior art are avoided, so that the workload of operators is reduced.

Description

Technical Field

[0001] This utility model relates to the field of stator frame assembly technology, and in particular to a device for installing stator bars on a stator frame. Background Technology

[0002] The stator winding is the main component of a generator that produces electrical energy. When an alternating magnetic field cuts the winding, an alternating electromotive force and an alternating current are generated in the winding, which is how the generator produces electricity.

[0003] The stator winding is constructed by mounting several stator bars circumferentially on the stator frame. Due to the strict requirements of the stator winding regarding ambient temperature, humidity, and dust prevention during the installation of the stator bars, the entire stator winding assembly process must be completed in a dedicated stator winding assembly shed.

[0004] Meanwhile, a single stator bar weighs approximately 70-80 kg and is about 6 m long, consisting of a long, narrow copper structure. Because the space in the stator winding assembly shed is relatively enclosed and limited, it is not suitable to use large lifting machinery (factory cranes) to hoist the stator bars. The traditional hoisting method involves setting up lifting points above the stator bars to be installed and suspending hoists. Workers move the stator bars to a suitable location for hoisting, then use the suspended hoists to lift them and install them onto the stator base. After the bar installation is completed, the lifting points and hoists are rearranged to proceed with the hoisting of the next stator bar in the next location. This allows for the circumferential installation of the stator bars.

[0005] While this method effectively installs the stator bars onto the stator frame, it requires frequent changes to the lifting points and re-suspending of the hoist, resulting in a significant workload. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a device for mounting stator bars on a stator frame. To achieve the above objective, this utility model adopts the following technical solution:

[0007] An apparatus for mounting stator bars on a stator frame, the stator frame comprising a top ring plate and a bottom ring plate disposed opposite to the top ring plate, the opposing top ring plate and the bottom ring plate forming a cavity, and a connecting plate disposed within the cavity for connecting the top ring plate and the bottom ring plate together.

[0008] The device for mounting stator bars on the stator frame includes a fixing mechanism and a rotating mechanism, wherein the rotating mechanism is optionally equipped with a hoisting mechanism for hoisting the stator bars.

[0009] The fixing mechanism is arranged along the diameter of the top ring plate and is fixed to the top ring plate. One end of the rotating mechanism is located in the cavity, and the other end extends to the middle of the fixing mechanism and is rotatably connected to the fixing mechanism so that the rotating mechanism can rotate circumferentially around the fixing mechanism in the cavity.

[0010] Furthermore, a sliding mechanism is provided on the rotating mechanism that can be connected to the hoisting mechanism. The sliding mechanism is configured to allow movement along the axial direction of the rotating mechanism, so that the sliding mechanism can drive the hoisting mechanism to move along the axial direction of the rotating mechanism.

[0011] Furthermore, the connecting plate extends upward along the outer lateral side of the bottom ring plate to the top ring plate, so that the inner lateral side of the bottom ring plate forms a support platform. A support mechanism is provided on the support platform, and the free end of the support mechanism is connected to the free end of the rotating mechanism to support the rotating mechanism and allow the rotating mechanism to move circumferentially along the path formed by the support platform.

[0012] Furthermore, the support mechanism is also equipped with traveling wheels, which are configured to abut against the support platform to drive the support mechanism to move circumferentially along the support platform.

[0013] Furthermore, the device for mounting stator bars on the stator base also includes a connecting mechanism disposed in the middle of the fixing mechanism and configured to connect with the end of the rotating mechanism to allow the rotating mechanism to rotate circumferentially within the cavity.

[0014] Furthermore, the connecting mechanism includes a bolt disposed in the middle of the fixing mechanism and extending vertically downward, and a nut that mates with the bolt. A through hole is provided on the rotating mechanism for fitting onto the bolt to allow the rotating mechanism to rotate circumferentially around the bolt. The nut is configured to limit the vertical downward movement of the rotating mechanism along the bolt.

[0015] Furthermore, the rotating mechanism includes a sliding surface, a limiting surface disposed opposite to the sliding surface, and a connecting surface disposed between the sliding surface and the limiting surface for connecting the sliding surface and the limiting surface together. The sliding mechanism is sleeved on the sliding surface for moving along the axial direction of the sliding surface, and the upward movement is restricted by the limiting surface.

[0016] Furthermore, the sliding mechanism includes a sliding plate, with upwardly extending fixed plates on both sides of the sliding plate, and limiting plates extending laterally inward toward each fixed plate. The limiting plates are configured to abut against each other with the limiting surface, and vertically downward extending snap-fit ​​plates are provided on each limiting plate. The snap-fit ​​plates and the sliding plate together form a receiving area for accommodating the sliding surface, allowing the receiving area to move along the sliding surface.

[0017] Furthermore, a connecting ring is provided on the sliding plate, which is configured to be fixed together with the hoisting mechanism.

[0018] Furthermore, the hoisting mechanism includes a hoisting hoist and flexible connecting parts disposed at the two force-applying ends of the hoisting hoist, such that the flexible connecting part at one end is fixed together with the connecting ring, and the flexible connecting part at the other end is used to fix and connect the stator bars.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention includes a fixing mechanism and a rotating mechanism, with a selectively configured lifting mechanism for hoisting the stator bars on the rotating mechanism. The fixing mechanism is positioned along the diameter of the top ring plate and fixed to it. One end of the rotating mechanism is located within the cavity, while the other end extends to the middle of the fixing mechanism and is rotatably connected to it, allowing the rotating mechanism to rotate circumferentially around the fixing mechanism within the cavity. This configuration enables the stator bars, hoisted by the lifting mechanism, to rotate circumferentially within the cavity. Thus, a single hoisting mechanism setup is sufficient for the circumferential installation of the stator bars. This method avoids the frequent changes in lifting points and re-suspension of the hoisting hoist required in existing technologies, thereby reducing the workload of operators.

Detailed Implementation

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0031] To better understand the purpose, structure, and function of this utility model, the following detailed description, in conjunction with the accompanying drawings, provides an apparatus for mounting stator bars on a stator frame.

[0032] For convenience, the direction extending along the stator frame will be referred to as "vertical", "vertical direction" or similar terms, and the direction perpendicular to "vertical" or "vertical direction" will be referred to as "lateral", "horizontal direction" or similar terms.

[0033] like Figure 1 As shown, the stator frame 10 is a component used to accommodate stator bars (not shown) and to fix the stator bars relatively to the stator frame 10. In this way, the stator bars and the stator frame 10 can together form a device for generating electricity.

[0034] In the prior art, the stator frame 10 includes a top ring plate 101 and a bottom ring plate 102 disposed opposite to the top ring plate 101. The opposing top ring plate 101 and bottom ring plate 102 together form a cavity 103, and a connecting plate 104 for connecting the top ring plate 101 and the bottom ring plate 102 is disposed within the cavity 103. It should be noted that the stator bars, the stator frame 10, and the installation relationship between the stator bars and the stator frame 10 are well known to those skilled in the art.

[0035] Figure 1 The schematic diagram illustrates the overall structure of the device for mounting stator bars on a stator frame according to the present invention. In such a way... Figure 1 In the embodiment shown, the device for mounting stator bars on the stator frame includes a fixing mechanism 1 and a rotating mechanism 2, wherein a hoisting mechanism 3 for hoisting stator bars (not shown in the figure) is selectively provided on the rotating mechanism 2.

[0036] In this embodiment, as Figure 1 As shown, the fixing mechanism 1 is arranged along the diameter direction of the top ring plate 101 and is fixed to the top ring plate 101. One end of the rotating mechanism 2 is located in the cavity 104, and the other end extends to the middle of the fixing mechanism 1 and is rotatably connected to the fixing mechanism 1 so that the rotating mechanism 2 can rotate circumferentially around the fixing mechanism 1 in the cavity 103.

[0037] In this way, such as Figure 1 As shown, when it is necessary to install stator bars (not shown in the figure) on the stator frame 10, the fixing mechanism 1 can be set along the diameter direction of the top ring plate 101, so that the fixing mechanism 1 and the top ring plate 101 are fixed together.

[0038] Meanwhile, a rotating mechanism 2 is provided on the fixed mechanism 1, with its end located at the middle of the fixed mechanism 1, and the rotating mechanism 2 is rotatably connected to the fixed mechanism 1. This arrangement allows the free end of the rotating mechanism 2 to rotate circumferentially around the middle of the fixed mechanism 1 within the cavity 103. Furthermore, a lifting mechanism 3 is provided on the rotating mechanism 2. This allows the lifting mechanism 3 to lift the stator bars (not shown in the figure).

[0039] In this process, the stator bars are first hoisted to a position flush with the stator frame 10 to be installed using the hoisting mechanism 3. Then, a force is applied to the rotating mechanism 2, causing it to rotate around the fixing mechanism 1 until it is aligned with the installation position. During this process, the rotating mechanism 2 drives the hoisting mechanism 3 to move synchronously, thereby aligning the stator bars with the installation position. Finally, a force is applied to the stator bars to install them onto the stator frame 10.

[0040] In one embodiment, such as Figure 2 As shown, a sliding mechanism 4 is provided on the rotating mechanism 2, which can be connected to the hoisting mechanism 3. In this embodiment, the sliding mechanism 4 is configured to allow movement along the axial direction of the rotating mechanism 2.

[0041] In this configuration, when it is necessary to install stator bars (not shown in the figure) on the stator frame 10, the fixing mechanism 1 can be set along the diameter direction of the top ring plate 101, so that the fixing mechanism 1 and the top ring plate 101 are fixed together.

[0042] Meanwhile, a rotating mechanism 2 is provided on the fixed mechanism 1, with its end located at the middle of the fixed mechanism 1, and the rotating mechanism 2 is rotatably connected to the fixed mechanism 1. This arrangement allows the free end of the rotating mechanism 2 to rotate circumferentially around the middle of the fixed mechanism 1 within the cavity 103. Furthermore, a sliding mechanism 4 is provided on the rotating mechanism 2, and a lifting mechanism 3 is provided on the sliding mechanism 4.

[0043] Then, the stator bars (not shown in the figure) are placed in a location convenient for hoisting, and hoisted to the level of the installation position on the stator frame 10 using the hoisting mechanism 3. Simultaneously, a force is applied to the rotating mechanism 2, causing it to rotate around the fixed mechanism 1 until it is aligned with the installation position. During this process, the rotating mechanism 2 drives the sliding mechanism 4 to move synchronously, which in turn drives the hoisting mechanism 3 and the stator bars located on the hoisting mechanism 3 to move synchronously.

[0044] At this point, a force is applied to the sliding mechanism 4, causing it to move along the axis of the rotating mechanism 2 until the stator bar moves to the installation position. This allows the stator bar to be installed on the stator frame 10.

[0045] In one embodiment, such as Figure 1As shown, the connecting plate 104 extends upward from the outer lateral side of the bottom ring plate 102 to the top ring plate 101, so that a support platform 105 is formed on the inner lateral side of the bottom ring plate 102. In this embodiment, a support mechanism 5 is provided on the support platform 105, and the free end of the support mechanism 5 is connected to the free end of the rotating mechanism 2 to support the rotating mechanism 2 and allow the rotating mechanism 2 to move circumferentially along the path formed by the support platform 105.

[0046] In one embodiment, such as Figure 2 As shown, the support mechanism 5 includes a first support rod 51, a second support rod 52, and a third support rod 53. In this embodiment, the first support rod 51, the second support rod 52, and the third support rod 53 are connected end-to-end to form a triangular structure that can stably support the rotating mechanism 2. The rotating mechanism 2 is located at the connection between the first support rod 51 and the second support rod 52.

[0047] According to a preferred embodiment of the present invention, such as Figure 2 As shown, a traveling wheel 54 is also provided on the support mechanism 5. Specifically, the traveling wheel 54 is mounted on the third support rod 53 and configured to abut against the support platform 105, thereby driving the support mechanism 5 to move circumferentially along the support platform 105. In this way, when the support mechanism 5 moves along the support platform 105, the traveling wheel 54 can change the sliding friction between the support mechanism 5 and the support platform 105 into rolling friction, thus facilitating the movement of the support mechanism 5 on the support platform 105.

[0048] According to a preferred embodiment of the present invention, such as Figure 2 As shown, the support mechanism 5 also includes a reinforcing rib 55, which is inclinedly disposed between the first support rod 51 and the second support rod 52. This enhances the connection strength of the support mechanism 5.

[0049] In one embodiment, such as Figure 2 As shown, the device for mounting stator bars on the stator frame further includes a connecting mechanism 6, which is disposed in the middle of the fixing mechanism 1 and configured to connect with the end of the rotating mechanism 2 to allow the rotating mechanism 2 to rotate circumferentially within the cavity 103.

[0050] In this embodiment, as Figure 4 As shown, the connecting mechanism 6 includes a bolt 61 disposed in the middle of the fixing mechanism 1 and extending vertically downward, and a nut 62 that cooperates with the bolt 61. Meanwhile, the rotating mechanism 2 is also provided with a through hole 21, which is used to fit onto the bolt 61, allowing the rotating mechanism 2 to rotate circumferentially around the bolt 61.

[0051] In this way, when the rotating mechanism 2 needs to rotate within the cavity 103, a force is applied to the free end of the rotating mechanism 2 to rotate along the cavity 103. At this time, the end of the rotating mechanism 2 will rotate around the nut 62, causing the free end of the rotating mechanism 2 to rotate circumferentially within the cavity 103.

[0052] Furthermore, the nut 62 is configured to limit the vertical downward movement of the rotating mechanism 2 along the bolt 61. In this way, the rotating mechanism 2 cannot move vertically downward, thereby preventing the rotating mechanism 2 from disengaging from the bolt 61.

[0053] According to a preferred embodiment of the present invention, such as Figure 2 As shown, the vertical height of the bolt 61 and nut 62 after engagement with the fixing mechanism 1 allows the rotating mechanism 2 to be arranged horizontally along the support mechanism 5. Specifically, the bolt 61 and nut 62, after engagement, work together with the support mechanism 5 to apply force to the rotating mechanism 2, enabling the rotating mechanism 2 to be positioned horizontally.

[0054] In one embodiment, such as Figure 2 As shown, the rotating mechanism 2 includes a sliding surface 22, a limiting surface 23 opposite to the sliding surface 22, and a connecting surface 24 disposed between the sliding surface 22 and the limiting surface 23, for connecting the sliding surface 22 and the limiting surface 23 together. In this embodiment, the sliding mechanism 4 is sleeved on the sliding surface 22 and configured to allow movement along the axial direction of the sliding surface 22. Simultaneously, the upward movement of the sliding mechanism 4 is restricted by the limiting surface 23. In this way, the sliding mechanism 4 can be stably mounted on the rotating mechanism 2, and the sliding mechanism 4 can move stably along the axial direction of the sliding surface 22.

[0055] In one embodiment, such as Figure 5 , 6 As shown, the sliding mechanism 4 includes a sliding plate 41, with upwardly extending fixed plates 42 on both sides of the sliding plate 41. Each fixed plate 42 is provided with a limiting plate 43 extending laterally inward toward the fixed plate 42. The limiting plate 43 is configured to abut against the limiting surface 23. Each limiting plate 43 is provided with a vertically downward extending snap-fit ​​plate 44. The snap-fit ​​plate 44 and the sliding plate 41 together form a receiving area 45 for accommodating the sliding surface 22, allowing the receiving area 45 to move along the sliding surface 22.

[0056] In this way, such as Figure 6As shown, the receiving area 45 can be fitted onto the sliding surface 22, thereby allowing the sliding mechanism 4 to move smoothly along the sliding surface 22. Simultaneously, the limiting surface 23 can also limit the upward movement of the sliding mechanism 4. Therefore, the sliding mechanism 4 can further move smoothly along the sliding surface 22.

[0057] In one embodiment, such as Figure 6 As shown, a connecting shaft 46 is also provided between the fixed plate 42 and the snap-fit ​​plate 44, and a roller 47 is provided on the connecting shaft 46. In this embodiment, the roller 47 is configured to allow it to abut against the sliding plate 41. In this way, when the sliding mechanism 4 moves along the sliding plate 41, the roller 47 can change the sliding friction between the sliding mechanism 4 and the sliding plate 41 into rolling friction, thereby facilitating the movement of the sliding mechanism 4 on the sliding plate 41.

[0058] According to a preferred embodiment of the present invention, such as Figure 3 As shown, a connecting ring 411 is also provided on the sliding plate 41, and the connecting ring 411 is configured to be fixedly connected to the hoisting mechanism 3. In this embodiment, the hoisting mechanism 3 includes a hoisting hoist 31 and flexible connecting parts 32 provided at the two force-applying ends of the hoisting hoist 31, such that one end of the flexible connecting part 32 is fixedly connected to the connecting ring 411, and the other end of the flexible connecting part 32 is used to fixally connect to the stator bars. In this way, the sliding mechanism 4 can be stably connected to the hoisting mechanism 3.

[0059] In one embodiment, such as Figure 2 As shown, the fixing mechanism 1 includes an abutment plate 11, which is configured as a planar structure for mounting on the top ring plate 101, thereby forming a surface contact with the top ring plate 101. Meanwhile, as... Figure 7 As shown, the fixing mechanism 1 further includes at least a fixing member 12, the two ends of which are configured to abut against the top ring plate 101 and the abutment plate 11 respectively, for fixing the top ring plate 101 and the abutment plate 11 together. In this embodiment, the fixing member 12 is configured as a C-shaped clip. It should be noted that the structure and fixing method of the C-shaped clip are well known to those skilled in the art.

[0060] According to a preferred embodiment of the present invention, such as Figure 2As shown, the fixing mechanism 1 also includes a reinforcing plate 13 disposed opposite to the abutment plate 11, and a rib plate 14 disposed between the abutment plate 11 and the reinforcing plate 13 for connecting the abutment plate 11 and the reinforcing plate 13 together. Specifically, the abutment plate 11, the rib plate 14, and the reinforcing plate 13 together form an "I"-shaped structure. In this way, the strength of the fixing mechanism 1 can be enhanced.

[0061] The operation of the device for installing stator bars on the stator frame according to this utility model is as follows.

[0062] First, the fixing mechanism 1 is mounted on the top ring plate 101, and fixed to the top ring plate 101 by the fastener 12. Simultaneously, the through hole 21 on the rotating mechanism 2 is fitted onto the bolt 61 located on the fixing mechanism 1, and a nut 62 is screwed onto the bolt 61, limiting the vertical downward movement of the rotating mechanism 2. This allows the free end of the rotating mechanism 2 to rotate circumferentially around the center of the fixing mechanism 1 within the cavity 103. Next, a support mechanism 5 is provided at the free end of the rotating mechanism 2 to support the rotating mechanism 2 and allow it to move circumferentially along the path formed by the support platform 105.

[0063] Furthermore, the receiving area 45 located on the sliding mechanism 4 is fitted onto the sliding surface 22, and the limiting plate 43 is positioned to abut against the limiting surface 23. In this way, the sliding mechanism 4 moves smoothly along the sliding surface 22. Simultaneously, the limiting surface 23 limits the upward movement of the sliding mechanism 4. Then, a lifting mechanism 3 is installed on the sliding mechanism 4. Thus, the assembly of this device is completed.

[0064] When it is necessary to install the stator bars (not shown in the figure) on the stator frame 10, the stator bars (not shown in the figure) are placed in a position that facilitates hoisting, and the hoisting mechanism 3 is used to hoist the stator bars to a position flush with the installation position on the stator frame 10. Simultaneously, a force is applied to the support mechanism 5, causing the support mechanism 5 to drive the rotating mechanism 2 to move circumferentially along the support platform 105 until the rotating mechanism 2 is aligned with the installation position. During this process, the rotating mechanism 2 will drive the sliding mechanism 4 to move synchronously, which in turn will drive the hoisting mechanism 3 and the stator bars located on the hoisting mechanism 3 to move synchronously.

[0065] At this point, a force is applied to the sliding mechanism 4, causing it to move along the axis of the rotating mechanism 2 until the stator bar moves to the installation position. This allows the stator bar to be installed on the stator frame 10.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
