Description

Technical Field

[0001] This utility model relates to the field of electronic device testing technology, and in particular to a tool and testing method for adjusting the stator positioning ribs of a pumped storage power station generator. Background Technology

[0002] The positioning ribs of the generator stator in a pumped storage power station are not only large in size but also numerous, so they need to be precisely installed in their preset positions during assembly. Currently, the adjustment of the reference positioning ribs is done by temporarily fixing the positioning ribs and the support blocks to the ring plate of the base using a C-clamp and a support block top tool. First, the radius of the annular cage formed by the positioning ribs is measured with an inside micrometer. Then, the radial and tangential inclination of the positioning ribs is measured by rotating a circular measuring frame set in the middle to monitor the dial indicator values. During the adjustment, the circumferential, radial, and tangential inclination of the positioning ribs are controlled by tapping the support blocks with a copper hammer to control the radius and radial torsion of the positioning ribs. It is particularly difficult to control the changes in dimensions during the process, repeated adjustments increase the working time, and the deviation is large, so the accuracy cannot be guaranteed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a tool for adjusting the positioning ribs of the generator stator in a pumped storage power station, so as to solve the problem in the prior art that it is difficult to control the dimensional changes of the positioning ribs, resulting in repeated adjustments of the positioning ribs and poor adjustment accuracy.

[0004] To achieve the above objectives, this utility model provides a tool for adjusting the positioning ribs of a generator stator in a pumped storage power station, comprising:

[0005] The external mounting frame is fixed to the base of the pumped storage power station;

[0006] An inner mounting frame is rotatably disposed within the outer mounting frame, and the inner mounting frame rotates along the height direction of the outer mounting frame;

[0007] A rotating frame is rotatably disposed within the inner mounting frame. The rotating frame rotates along the width direction of the inner mounting frame, and a limiting groove is provided on the rotating frame.

[0008] The positioning frame is pulled out and installed on the side of the rotating frame with a limiting groove. The positioning rib is installed in the limiting groove and is clamped by the positioning frame. The inner mounting frame rotates relative to the outer mounting frame, and the rotating frame rotates relative to the inner mounting frame to adjust the angle of the positioning rib.

[0009] Optionally, the height of the outer mounting frame is more than twice the height of the inner mounting frame.

[0010] Optionally, the width of the rotating frame is smaller than the internal width of the inner mounting frame.

[0011] Optionally, the rotating frame is provided with a through hole, and the positioning frame is pulled out and disposed in the through hole.

[0012] Optionally, the rotating frame is provided with a clamping screw on the side away from the limiting groove, and the positioning frame includes a sliding frame. One end of the sliding frame passes through the through hole and is threadedly connected to the clamping screw. When the clamping screw rotates, the sliding frame is pulled out of the through hole.

[0013] Optionally, the sliding frame has a clamping plate at one end away from the clamping screw, and the clamping plate corresponds to the limiting groove.

[0014] Optionally, the left and right side walls of the inner mounting frame are rotatably mounted inside the outer mounting frame via a first pivot. A pitch angle adjustment component is mounted on the side wall of the outer mounting frame, and the pitch angle adjustment component is connected to one of the first pivots.

[0015] Optionally, the pitch angle adjustment assembly includes a pitch angle worm gear, a pitch angle worm, and a pitch angle screw head. The pitch angle worm gear is connected to the first rotating shaft, the pitch angle worm is rotatably mounted on the side wall of the outer mounting frame and meshes with the pitch angle worm gear, and the end of the pitch angle worm is connected to the pitch angle screw head.

[0016] Optionally, the top and bottom of the rotating frame are rotatably mounted in the inner mounting frame via corresponding second rotating shafts. The top of the inner mounting frame is provided with a left-right angle adjustment component, which is connected to the second rotating shaft at the top.

[0017] Optionally, the left and right angle adjustment assembly includes a left and right angle worm gear, a left and right angle worm, and a left and right angle screw head. The left and right angle worm gear is connected to the second rotating shaft at the top. The left and right angle worm is rotatably disposed at the top of the rotating frame and meshes with the left and right angle worm gear. The end of the left and right angle worm is connected to the left and right angle screw head.

[0018] As described above, the tool for adjusting the stator positioning ribs of a pumped storage power station generator provided by this utility model includes: an outer mounting frame, an inner mounting frame rotatably mounted within the outer mounting frame, and a rotating frame rotatably mounted within the inner mounting frame. The rotating frame is equipped with a positioning bracket for fixing the positioning ribs; that is, the positioning ribs are fixed to the rotating frame via the positioning bracket. When the inner mounting frame and the rotating frame rotate, the positioning ribs can rotate at an angle. The inner mounting frame can rotate along the height direction of the outer mounting frame, which is equivalent to adjusting the height rotation of the positioning ribs when the inner mounting frame rotates. The rotating frame is located within the inner mounting frame and rotates along the width direction of the inner mounting frame, allowing adjustment of the thickness rotation of the positioning ribs when the rotating frame rotates relative to the inner mounting frame. By fixing the positioning ribs to the rotating frame via the positioning bracket, the horizontal rotation of the positioning ribs can be adjusted when the rotating frame rotates relative to the inner mounting frame, and the vertical rotation of the positioning ribs can be adjusted when the inner mounting frame rotates relative to the outer mounting frame. This allows for fixed adjustment of the positioning ribs' adjustment direction, avoiding repeated adjustments and ensuring the adjustment accuracy of the positioning ribs.

[0028] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, this utility model provides a tool for adjusting the positioning ribs of the generator stator in a pumped storage power station, comprising:

[0030] The outer mounting frame 1 is fixed to the base of the pumped storage power station;

[0031] The inner mounting frame 2 is rotatably disposed within the outer mounting frame 1, and the inner mounting frame 2 rotates along the height direction of the outer mounting frame 1;

[0032] A rotating frame 3 is rotatably disposed within the inner mounting frame 2. The rotating frame 3 rotates along the width direction of the inner mounting frame 2. A limiting groove 31 is provided on the rotating frame 3.

[0033] The positioning frame 4 is pulled out and installed on the side of the rotating frame 3 where the limiting groove 31 is provided. The positioning rib 7 is installed in the limiting groove 31 and is clamped by the positioning frame 4. The inner mounting frame 2 rotates relative to the outer mounting frame 1 and the rotating frame 3 rotates relative to the inner mounting frame 2 to adjust the angle of the positioning rib 7.

[0034] Specifically, the pumped storage power station's base includes an upper ring plate 81 and a lower ring plate 82. An adjustment tool sits on the lower ring plate 82. A top post 9 is provided on the upper ring plate 81, and the top post 9 is pressed against the outer mounting frame 1 of the adjustment tool to fix it in place. The top post 9 can be understood as a cylinder. This allows the adjustment tool to stably adjust the positioning rib 7. The adjustment tool includes an outer mounting frame 1, an inner mounting frame 2 rotatably mounted within the outer mounting frame 1, and a rotating frame 3 rotatably mounted within the inner mounting frame 2. The rotating frame 3 is equipped with a positioning frame 4 for fixing the positioning rib 7. The rotating frame 3 has a positioning groove, and the positioning rib 7 is located within the positioning groove; that is, the positioning rib 7 is fixed within the positioning groove of the rotating frame 3 by the positioning frame 4. When the inner mounting frame 2 and the rotating frame 3 rotate, the positioning rib 7 can rotate at an angle. A limiting groove 31 is provided on one side of the rotating frame 3. The limiting groove 31 is used to place the positioning rib 7. The width of the limiting groove 31 matches the width of the positioning rib 7. Therefore, when the positioning rib 7 is rotated to adjust the angle, the limiting groove 31 makes the positioning rib 7 more stable under the limitation, preventing the positioning rib 7 from being misaligned or shaking. The inner mounting frame 2 can rotate along the height direction of the outer mounting frame 1, which means that the rotation of the positioning rib 7 in the height direction can be adjusted when the inner mounting frame 2 rotates. The rotating frame 3 is set inside the inner mounting frame 2 and rotates along the width direction of the inner mounting frame 2. When the rotating frame 3 rotates, the rotation of the positioning rib 7 in the thickness direction can be adjusted. The positioning rib 7 is fixed on the rotating frame 3 by the positioning frame 4. When the rotating frame 3 rotates relative to the inner mounting frame 2, the horizontal rotation of the positioning rib 7 can be adjusted. When the inner mounting frame 2 rotates relative to the outer mounting frame 1, the vertical rotation of the positioning rib 7 can be adjusted. This allows for fixed adjustment of the positioning rib 7, avoiding repeated adjustment of the positioning rib 7 and ensuring the adjustment accuracy of the positioning rib 7.

[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, the height of the outer mounting frame 1 is more than twice the height of the inner mounting frame 2.

[0036] Specifically, the internal height of the outer mounting frame 1 is twice the external height of the inner mounting frame 2. This ensures that the inner mounting frame 2 can rotate at a large angle within the outer mounting frame 1, allowing the inner mounting frame 2 to drive the positioning rib 7 to make large-angle adjustments. This avoids the problem that the rotation angle of the inner mounting frame 2 is limited due to the small distance between the outer mounting frame 1 and the inner mounting frame 2.

[0037] In some embodiments, such as Figure 2 and Figure 3 As shown, the width of the rotating frame 3 is smaller than the internal width of the inner mounting frame 2.

[0038] Specifically, the width of the rotating frame 3 is smaller than the internal width of the inner mounting frame 2. The optimal distance between the rotating frame 3 and the inner mounting frame 2 is 5m. This allows the rotating frame 3 to swing left and right within the inner mounting frame 2 at the maximum angle, thereby enabling the positioning rib 7 to achieve large-angle adjustment in the horizontal direction.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the rotating frame 3 has a through hole, and the positioning frame 4 is pulled out and installed in the through hole.

[0040] Specifically, two through holes are symmetrically provided on the side wall of the rotating frame 3. The through holes are rectangular in shape and match the shape of the positioning frame 4. The positioning frame 4 is a square frame structure. The frame of the positioning frame 4 passes through the through holes and can be pulled out relative to the through holes. When the positioning frame 4 is pulled tight relative to the rotating frame 3, the positioning rib 7 can be locked.

[0041] In some embodiments, such as Figure 2 and Figure 3 As shown, the rotating frame 3 is provided with a clamping screw 32 on the side away from the limiting groove 31. The positioning frame 4 includes a sliding frame 41. One end of the sliding frame 41 passes through the through hole and is threadedly connected to the clamping screw 32. When the clamping screw 32 rotates, the sliding frame 41 is pulled out in the through hole.

[0042] Specifically, the rotating frame 3 is provided with clamping screws 32 at some points away from the limiting groove 31. The clamping screws 32 are rotatably mounted on the rotating frame 3. The positioning frame 4 includes a sliding frame 41, which passes through the through hole on the rotating frame 3 and is threadedly connected to the clamping screws 32. When the construction personnel rotate the clamping screws 32, the sliding frame 41 can move along the length direction of the clamping screws 32, thereby enabling the sliding frame 41 to be pulled on the rotating frame 3. This can lock the positioning rib 7 to the rotating frame 3, facilitating the positioning of the positioning rib 7.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the sliding frame 41 has a clamping plate 42 at one end away from the clamping screw 32, and the clamping plate 42 corresponds to the limiting groove 31.

[0044] Specifically, a clamping plate 42 is provided at the end of the sliding frame 41 away from the clamping screw 32. The clamping plate 42 can abut against the side wall of the positioning rib 7, thereby locking the positioning rib 7. The clamping plate 42 is a single plate fixed to the end of the sliding frame 41. This plate is detachable, that is, the clamping plate 42 is detachably installed at the end of the sliding frame 41. When locking the positioning rib 7, the positioning rib 7 is first placed in the limiting groove 31 of the rotating frame 3, and then the clamping plate 42 is fixed to the end of the sliding frame 41, thereby limiting the positioning rib 7. By rotating the clamping screw 32, the clamping plate 42 and the positioning groove can clamp the positioning rib 7.

[0045] In some embodiments, such as Figure 4 As shown, the left and right sides of the inner mounting frame 2 are rotatably mounted inside the outer mounting frame 1 via a first rotating shaft 21. A pitch angle adjustment component 5 is mounted on the side wall of the outer mounting frame 1, and the pitch angle adjustment component 5 is connected to one of the first rotating shafts 21.

[0046] Specifically, the left and right walls of the inner mounting frame 2 are connected to the outer mounting frame 1 via a first rotating shaft 21. One of the first rotating shafts 21 passes through the outer mounting frame 1. For example, the first rotating shaft 21 on the right side wall of the inner mounting frame 2 passes through the outer mounting frame 1 and is connected to the pitch angle adjustment component 5. The pitch angle adjustment component 5 can drive the first rotating shaft 21 to rotate, thereby causing the inner mounting frame 2 to rotate within the outer mounting frame 1, which can realize the vertical angle adjustment of the positioning rib 7.

[0047] Furthermore, such as Figure 3 and Figure 4 As shown, the pitch angle adjustment assembly 5 includes a pitch angle worm gear 52, a pitch angle worm 51, and a pitch angle screw head 53. The pitch angle worm gear 52 is connected to the first rotating shaft 21. The pitch angle worm 51 is rotatably mounted on the side wall of the outer mounting frame 1 and meshes with the pitch angle worm gear 52. The end of the pitch angle worm 51 is connected to the pitch angle screw head 53.

[0048] Specifically, the pitch angle adjustment assembly 5 includes a pitch angle worm gear 52, a pitch angle worm 51, and a pitch angle screw head 53. The pitch angle worm gear 52 is sleeved on the first rotating shaft 21, and the pitch angle worm 51 is rotatably mounted on a mounting seat on the outer mounting frame 1. The pitch angle worm 51 meshes with the pitch angle worm gear 52, and the pitch angle screw head 53 is located at the end of the pitch angle worm 51 away from the pitch angle worm gear 52. In this way, the operator can adjust the rotation of the pitch angle worm 51 by rotating the pitch angle screw head 53. The pitch angle worm 51 drives the pitch angle worm gear 52 to rotate, thereby realizing the adjustment of the rotation angle of the inner mounting frame 2, and at the same time realizing the adjustment of the vertical angle of the positioning rib 7. The pitch angle worm gear 52 and the pitch angle worm 51 have self-locking properties, and only the worm can drive the worm gear.

[0049] In some embodiments, such as Figure 4 As shown, the top and bottom of the rotating frame 3 are rotatably mounted in the inner mounting frame 2 via corresponding second rotating shafts 33. The top of the inner mounting frame 2 is provided with a left and right angle adjustment component 6, which is connected to the second rotating shaft 33 at the top.

[0050] Specifically, the top and bottom of the rotating frame 3 are connected to the inner mounting frame 2 via a second rotating shaft 33. One of the second rotating shafts 33 is set through the inner mounting frame 2. For example, the first rotating shaft 21 on the right side wall of the rotating frame 3 is set through the inner mounting frame 2 and is connected to the left and right angle adjustment component 6. The left and right angle adjustment component 6 can drive the second rotating shaft 33 to rotate, thereby making the rotating frame 3 rotate within the inner mounting frame 2, which can realize the horizontal angle adjustment of the positioning rib 7.

[0051] Furthermore, such as Figure 3 and Figure 4 As shown, the left and right angle adjustment assembly 6 includes a left and right angle worm gear 62, a left and right angle worm 61, and a left and right angle screw head 63. The left and right angle worm gear 62 is connected to the second rotating shaft 33 at the top. The left and right angle worm 61 is rotatably disposed at the top of the rotating frame 3 and meshes with the left and right angle worm gear 62. The end of the left and right angle worm 61 is connected to the left and right angle screw head 63.

[0052] Specifically, the left and right angle adjustment component 6 includes a left and right angle worm gear 62, a left and right angle worm 61, and a left and right angle screw head 63. The left and right angle worm gear 62 is sleeved on the second rotating shaft 33, and the left and right angle worm 61 is rotatably mounted on the mounting seat on the inner mounting frame 2. The left and right angle worm 61 meshes with the left and right angle worm gear 62, and the left and right angle screw head 63 is located at the end of the left and right angle worm 61 away from the left and right angle worm gear 62. In this way, the operator can adjust the rotation of the left and right angle worm 61 by rotating the left and right angle screw head 63. The left and right angle worm 61 drives the left and right angle worm gear 62 to rotate, thereby realizing the adjustment of the rotation angle of the inner mounting frame 2, and at the same time realizing the adjustment of the vertical angle of the positioning rib 7. The left and right angle worm gear 62 and the left and right angle worm 61 have self-locking properties, and only the worm can drive the worm gear.

[0053] The specific usage process of this utility model is as follows:

[0054] When adjusting the stator positioning rib 7 of the generator in a pumped storage power station, first fix the adjustment tool on the base. The adjustment tool sits on the lower ring plate 82 of the base. The upper ring plate 81 of the base is equipped with a top column 9, which is pressed against the outer mounting frame 1 of the adjustment tool to fix it. After fixing, place the positioning rib 7 in the positioning groove of the rotating frame 3, and fix the clamping plate 42 to the end of the sliding frame 41 to limit the positioning rib 7 in the positioning groove. Then, by rotating the clamping screw 32, the sliding frame 41 moves along the length direction of the clamping screw 32, causing the sliding frame 41 to retract into the rotating frame 3. Then, the clamping plate 42 at the end of the sliding frame 41 clamps the positioning rib 7, and the positioning rib 7 is clamped in the limiting groove 31, thus achieving the positioning of the positioning rib 7. Then, adjust it according to the adjustment requirements. For example, when the horizontal angle of the positioning rib 7 needs to be adjusted, the left and right angle screw head 63 of the left and right angle adjustment component 6 is rotated to adjust the rotation of the left and right angle worm gear 61. The left and right angle worm gear 61 drives the left and right angle worm wheel 62 to rotate, thereby achieving the rotation angle adjustment of the inner mounting frame 2, and simultaneously achieving the vertical angle adjustment of the positioning rib 7. When the vertical angle of the positioning rib needs to be adjusted, the pitch angle screw head 53 of the pitch angle adjustment component 5 is rotated to adjust the rotation of the pitch angle worm gear 51. The pitch angle worm gear 51 drives the pitch angle worm wheel 52 to rotate, thereby achieving the rotation angle adjustment of the inner mounting frame 2.
