Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically a rotary pumped storage turbine base ring grinding equipment for construction sites. Background Technology

[0002] The seat ring structure of pumped storage units differs from that of cross-flow, axial flow, and mixed flow units, and has its own structural characteristics. During the installation of the seat ring, a certain amount of deformation will occur, requiring on-site machining of the seat ring in the turbine pit. The machining accuracy of the seat ring directly affects the overall quality of the turbine's guide vane mechanism, thus requiring the use of grinding equipment.

[0003] In actual turbine bearing ring grinding operations, mechanical grinding is mostly used due to the large size and complex structure of the bearing ring. However, after long-term operation, the turbine bearing ring will undergo microscopic deformation due to uneven stress distribution, resulting in a deviation between the actual curved surface and the theoretical model. Traditional mechanical grinding equipment can only rely on preset programs to execute grinding operations with fixed trajectories and parameters, which leads to uncontrolled contact between the grinding head and the workpiece. It is easy to over-cut in the concave area or under-cut in the convex area, thus affecting the overall grinding accuracy and quality. Utility Model Content

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Combination Figures 1-6 As shown, this utility model discloses a rotary pumped-storage turbine mounting ring on-site grinding equipment, including a pumped-storage turbine mounting ring 1 to be ground, and further comprising:

[0049] The placement platform 2 is located on the construction site and has a horizontal placement surface. The pumped storage turbine base ring 1 is hoisted and placed on the placement surface of the placement platform 2 to fix the pumped storage turbine base ring 1.

[0050] The rotary drive component 3 is mounted on the placement base 2 and can rotate and move along the periphery of the pumped storage turbine base ring 1.

[0051] An adaptive adjustment component 4 is mounted on the rotary drive component 3. A grinding component 5 is provided on the adjustment end of the adaptive adjustment component 4. The adaptive adjustment component 4 can rotate and move together with the rotary drive component 3 to dynamically adjust the grinding component 5 and realize the adaptive grinding of the pumped storage turbine seat ring 1.

[0052] During the grinding operation of the pumped-storage turbine seat ring 1, the seat ring to be ground is first placed on the horizontal surface of the placement platform 2 located at the construction site by hoisting. The stable support and fixing effect of the placement platform 2 ensures that the pumped-storage turbine seat ring 1 remains stable during the grinding process, preventing factors such as shaking from affecting the grinding effect. Next, the rotation drive assembly 3, installed on the placement platform 2, is activated. This assembly begins to rotate and displace along the circumference of the pumped-storage turbine seat ring 1, driving other connected components to move in a circular motion around the seat ring, allowing the grinding operation to cover all parts of the seat ring. The adaptive adjustment assembly 4, installed on the rotation drive assembly 3, rotates and displaces along with the rotation drive assembly 3. During this process, the adaptive adjustment assembly 4 senses the changes in the micro-morphology of the seat ring in real time. Based on the deviation between the actual curved surface of the seat ring and the theoretical model, it dynamically adjusts the grinding assembly 5 on its adjustment end, ensuring that the grinding assembly 5 closely conforms to the actual surface of the seat ring, achieving adaptive grinding of the seat ring's micro-morphology.

[0053] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 2As shown, the rotary drive assembly 3 includes:

[0054] The external toothed ring 31 is fixedly installed on the outside of the base 2;

[0055] A rotary displacement seat 32 is provided on the outside of the placement base 2, wherein the rotary displacement seat 32 is capable of rotating and displacing along the circumferential direction of the surface of the placement base 2, and the number of rotary displacement seats 32 is not less than two.

[0056] A drive motor 33 is fixedly mounted on the surface of the rotary displacement seat 32. A gear 34, meshing with an external gear ring 31, is fixedly mounted at the output end of the drive motor 33. Driven by the drive motor 33, the gear 34 meshes with the external gear ring 31 to move the rotary displacement seat 32 along the circumferential direction of the surface of the placement base 2. During the grinding operation of the pumped storage turbine seat ring 1, the external gear ring 31 is fixedly mounted on the outside of the placement base 2, providing a stable meshing foundation for the rotary displacement. At least two rotary displacement seats 32 are arranged on the outside of the placement base 2 and can move along the circumferential direction of the surface of the placement base 2. It should also be noted that a slide rail is provided on the outside of the placement base 2, and a sliding element is fixedly mounted on the surface of the rotary displacement seat 32. The rotary displacement seat 32 rotates and moves along the outside of the placement base 2 via the slide rail and the sliding element. When the rotary displacement seat 32 needs to be moved, the drive motor 33, which is fixedly installed on the surface of the rotary displacement seat 32, starts. The gear 34, which is fixedly installed at the output end of the drive motor 33, meshes with the external gear ring 31. The power generated by the operation of the drive motor 33 is transmitted to the external gear ring 31 through the gear 34. Since the external gear ring 31 is fixed, the gear 34 rotates under the drive of the drive motor 33. The meshing action with the external gear ring 31 causes the rotary displacement seat 32 to move along the circumferential direction of the surface of the placement base 2. Multiple rotary displacement seats 32 move in coordination, driving the adaptive adjustment component 4 and the grinding component 5 installed on them to move in a circular motion around the pumped storage turbine seat ring 1, thereby realizing the grinding treatment of various parts around the seat ring.

[0057] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 3 As shown, the adaptive adjustment component 4 includes:

[0058] The connecting arm 41 is fixedly installed on the surface of the rotary displacement seat 32, and it can move synchronously with the displacement of the rotary displacement seat 32.

[0059] A rotating base 42 is rotatably mounted on the surface of a connecting arm 41. The rotating base 42 is also provided with a limiting pin 43 that passes through the connecting arm 41. The limiting pin 43 restricts the position of the rotating base 42 on the connecting arm 41. The connecting arm 41 and the rotating base 42 are rotatably connected by a pin.

[0060] Vertical displacement component 44 is mounted on rotating base 42, and its displacement end is connected to grinding component 5.

[0061] The sensor component 45 is mounted on the vertical displacement component 44. Driven by the vertical displacement component 44, it dynamically adjusts the grinding component 5. When the rotary displacement seat 32 moves along the circumferential direction of the surface of the placement base 2 under the cooperation of the drive motor 33 and the external gear ring 31, the connecting arm 41 fixedly installed on the surface of the rotary displacement seat 32 moves synchronously, thereby driving the entire adaptive adjustment component 4 to move around the pumped storage turbine seat ring 1. Before placing the pumped-storage turbine seat ring 1, the rotating base 42 is rotated, causing the vertical displacement component 44 and the grinding assembly 5 to move, creating space for the hoisting and placement of the seat ring and avoiding mutual interference. After the seat ring is placed, the rotating base 42 is rotated back to its original position. At this time, the limiting pin 43 passing through the connecting arm 41 plays a role in limiting the position of the rotating base 42 on the connecting arm 41, ensuring its stability during the grinding process. Both the rotating base 42 and the connecting arm 41 have through holes adapted to the limiting pin 43, which are inserted into the inside of the through holes to fix the positions of the rotating base 42 and the connecting arm 41. During the grinding operation, the vertical displacement component 44 is set on the rotating base 42, and its displacement end is connected to the grinding assembly 5, which can drive the grinding assembly 5 to move vertically according to actual needs. The sensor component 45, which is set on the vertical displacement component 44, detects the distance between the grinding component 5 and the pumped storage turbine seat ring 1 in real time. When the seat ring has uneven surface due to micro-deformation and there is a deviation between the actual curved surface and the theoretical model, the sensor component 45 feeds back the detected distance change information to the control system. The control system drives the vertical displacement component 44 to move according to the feedback signal and dynamically adjusts the position of the grinding component 5 so that the grinding component 5 always maintains a suitable contact state and grinding pressure with the surface of the seat ring, thereby avoiding over-cutting in the concave area or under-cutting in the convex area. The vertical displacement component 44 is preferably a vertical electric slide.

[0062] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 As shown, the sensor component 45 includes:

[0063] The mounting base 451 is fixedly mounted on the surface of the vertical displacement member 44, and is parallel to the grinding surface of the grinding component 5.

[0064] A laser displacement sensor 452 is fixedly mounted on the surface of the mounting base 451, with its measuring end aligned with the polished surface.

[0065] A six-dimensional force sensor 453 is mounted on the moving end of the vertical displacement member 44 and connected to the grinding assembly 5. The mounting base 451 provides a stable mounting foundation for the laser displacement sensor 452. The laser displacement sensor 452 is fixedly mounted on the surface of the mounting base 451, with its measuring end aligned with the grinding surface. By emitting a laser beam and receiving the light reflected from the surface of the pumped storage turbine seat ring 1, it accurately measures the distance between the seat ring and the surface of the mounting base 451. Before the grinding assembly 5 begins grinding, it scans the contour of the seat ring's surface to be ground. When the laser displacement sensor 452 detects inconsistencies with the theoretical model, such as depressions on the seat ring's curved surface, it transmits the displacement change information to the control system. The control system adjusts the vertical displacement member 44 based on this information, thereby adjusting the feed rate of the grinding assembly 5 to ensure consistent grinding depth in different parts of the seat ring and avoid over-cutting in the recessed areas. Meanwhile, a six-dimensional force sensor 453, located at the moving end of the vertical displacement member 44 and connected to the grinding assembly 5, monitors the magnitude and direction of the contact force between the grinding assembly 5 and the surface of the seat ring to be ground in real time. During the grinding process, once the six-dimensional force sensor 453 detects a local concave area, i.e., an abnormal change in the contact force, it feeds the force signal back to the control system. Based on this force signal, the control system automatically adjusts the feed rate of the grinding assembly 5, such as increasing the pressure to compensate for insufficient grinding in the concave area, and simultaneously adjusts the rotation speed of the grinding assembly 5, such as reducing the rotation speed, to make the grinding process more precise. Through the synergistic effect of these two adjustments, the grinding quality problem caused by the unevenness of the seat ring surface is effectively compensated, achieving high-precision adaptive grinding of the microstructure of the pumped storage turbine seat ring 1.

[0066] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 and Figure 4 As shown, the polishing component 5 includes:

[0067] Grind the base 51 and set it on the detection end of the six-dimensional force sensor 453;

[0068] A grinding motor 52 is fixedly installed on the surface of a grinding base 51. A quick-release component 53 is provided on the output end of the grinding motor 52. The output end of the grinding motor 52 is connected to a grinding head 54 through the quick-release component 53. The grinding base 51 is set on the detection end of a six-dimensional force sensor 453. The six-dimensional force sensor 453 senses the magnitude and direction changes of the contact force between the grinding component 5 and the surface of the pumped storage turbine seat ring 1 in real time during the grinding process and feeds the force signal back to the control system. The grinding motor 52, fixedly mounted on the surface of the grinding base 51, serves as the power source. After starting, its output drives the quick-release component 53 and the grinding head 54 to rotate at high speed. The rotation of the grinding head 54 is used to grind the surface of the seat ring. When it is necessary to replace the grinding head 54 with a different type or a worn one, it can be quickly disassembled and installed through the quick-release component 53. This allows for flexible replacement of the appropriate grinding head 54 according to the grinding requirements of different parts of the seat ring and the actual grinding operation, thereby improving grinding efficiency and quality. The control system controls the speed of the grinding motor 52 and the feed amount of the grinding component 5 based on the force signal fed back by the six-dimensional force sensor 453 and the distance information detected by the laser displacement sensor 452. This ensures that the grinding head 54 can effectively grind the surface of the seat ring during the grinding process, while avoiding excessive pressure or improper speed. The position and number of the grinding head 54 are matched with the rotary displacement seat 32. One grinding head 54 can perform horizontal grinding, and the other grinding head 54 can perform vertical grinding.

[0069] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 4 and Figure 5 As shown, the quick-release component 53 includes:

[0070] The quick-release bracket 531 is fixedly installed on the output end of the grinding motor 52, and it can operate synchronously with the output end of the grinding motor 52.

[0071] Quick-release component 532 is disposed inside quick-release base 531, wherein quick-release component 532 can be displaced along the axial direction of quick-release base 531, and quick-release component 532 is fixedly connected to grinding head 54.

[0072] The limiting beads 533 are provided on the surface of the quick release base 531. The number of limiting beads 533 is set to a certain extent, and they are distributed in a ring at equal intervals around the center of the quick release base 531.

[0073] A limiting annular groove 534 is formed on the surface of the quick-release part 532, wherein the groove depth of the limiting annular groove 534 is adapted to the size of the limiting bead 533.

[0074] The elastic element 535 has one end fixedly installed on the surface of the quick-release base 531, and the other end is provided with a limiting ring 536, wherein the limiting ring 536 is sleeved on the outside of the quick-release base 531 and is used to abut the limiting bead 533 into the limiting annular groove 534, so as to realize the positioning of the quick-release base 531 and the quick-release element 532.

[0075] A limiting ring 537 is fitted onto the outside of the quick-release piece 532 and connected to a limiting abutment ring 536 to lock the position of the limiting abutment ring 536. When it is necessary to install the grinding head 54, the grinding head 54 connected to the quick-release piece 532 is aligned with the quick-release seat 531, and the quick-release piece 532 is pushed into the quick-release seat 531 along the axial direction. At this time, a number of limiting beads 533 are distributed on the surface of the quick-release seat 531 and arranged in a ring at equal intervals. The surface of the quick-release seat 531 has connecting holes that match the position and number of the limiting beads 533. These limiting beads 533 are located in the connecting holes, and due to the obstruction of the limiting abutment ring 536, the limiting beads 533 will not completely detach from the connecting holes. The limiting beads 533 will slightly displace outward under the pressure of the quick-release piece 532. When the quick-release component 532 is pushed to the appropriate position, the limiting annular groove 534 on its surface aligns with the limiting bead 533. Since the depth of the limiting annular groove 534 matches the size of the limiting bead 533, under the elastic force of the elastic component 535, the limiting abutment ring 536 at one end of the elastic component 535 abuts the limiting bead 533 into the limiting annular groove 534, thereby positioning and fixing the quick-release seat 531 and the quick-release component 532, thus securely installing the grinding head 54 and ensuring that the power of the grinding motor 52 can be effectively transmitted to the grinding head 54 for grinding operations. At the same time, the use of the limiting ring 537 locks the position of the limiting abutment ring 536, so that the limiting abutment ring 536 always abuts against the limiting bead 533 during the grinding process, further ensuring the stability of the entire quick release. The elastic component 535 is preferably a spring.

[0076] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 4 and Figure 5As shown, the outer wall of the limiting ring 537 is provided with external threads, and the inner wall of the limiting abutment ring 536 is provided with internal threads. The limiting ring 537 and the limiting abutment ring 536 are connected as one unit by threads. A connecting ring is fixedly installed on the inner wall of the limiting ring 537. The connecting ring is sleeved on the outside of the quick release part 532. Two limiting protrusions are also fixedly installed on the outer wall of the quick release part 532. The connecting ring is located between the two limiting protrusions. The external threads on the outer wall of the limiting ring 537 and the internal threads on the inner wall of the limiting abutment ring 536 are screwed together. When it is necessary to lock the position of the limiting abutment ring 536, the limiting ring 537 is rotated and tightened along the thread direction. The limiting ring 537 and the limiting abutment ring 536 are connected together by threads. Due to the obstruction of one of the limiting protrusions, the limiting abutment ring 536 will no longer be displaced, so that the limiting abutment ring 536 always abuts against the surface of the limiting bead 533. When it is necessary to disassemble the grinding head 54, rotate the limiting ring 537 in the opposite direction to gradually separate it from the limiting abutment ring 536. Move the limiting abutment ring 536 to the side away from the limiting ring 537. The elastic element 535 is in a compressed state, and the limiting bead 533 exits from the limiting annular groove 534. The quick release part 532 can be smoothly pulled out from the quick release seat 531, realizing the quick disassembly of the grinding head 54.

[0077] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 6 As shown, an air pump 6 is installed inside the placement base 2. The air pump 6 has an air pipe 7 connected to its suction end, and a dust collection hood 8 connected to the other end of the air pipe 7. The dust collection hood 8 is located at the exact center of the placement base 2. The air pump 6 has a filter component 9 connected to its outlet end via a pipe. When grinding the pumped storage turbine seat ring 1, the air pump 6 inside the placement base 2 is activated. Using the suction force generated at its suction end, the dust and debris generated during the grinding process are sucked in through the air pipe 7. Because the dust collection hood 8 is located at the exact center of the placement base 2, when the seat ring is placed on the placement base 2 for grinding, the dust generated will be quickly collected by the dust collection hood 8 under the action of the airflow, effectively preventing dust from flying around and polluting the construction site environment. The air pump 6 draws in dust-laden gas and delivers it to the filter component 9 through the outlet pipe. The filter component 9 filters the dust and debris in the gas, intercepting the dust and allowing the purified gas to be discharged, thus achieving effective dust collection and separation. The filter component 9 is a grinding dust collection filter box in the prior art. Its specific structure and working principle can be found through Internet searches and will not be described in detail here.

[0078] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 6As shown, a particle monitor 10 is also provided on the surface of the dust collection hood 8 to monitor the dust content at the placement base 2 in real time. The particle monitor 10 can continuously monitor the dust content at the placement base 2. When the monitored content is less than the set threshold, the operation of the air pump 6 can be stopped, thereby ensuring the cleanliness and health of the working environment at the grinding site.

[0079] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 As shown, there are several grinding heads 54, each with a different degree of roughness. In the initial stage of grinding, the surface of the seat ring may have large protrusions or uneven areas. At this time, a grinding head 54 with a higher degree of roughness can be selected to quickly remove excess material and efficiently perform preliminary grinding and shaping on the surface of the seat ring, thereby improving grinding efficiency. As the grinding work progresses, the surface of the seat ring gradually becomes smoother. At this time, a grinding head 54 with a moderate degree of roughness is used to further refine the grinding and correct the minor errors caused by the previous grinding. In the later stage of grinding, in order to achieve the high-precision surface quality required by the seat ring and meet the overall quality requirements of the turbine guide vane mechanism, a grinding head 54 with a lower degree of roughness is required for fine polishing. The quick-release component 53 allows for convenient and rapid replacement of the grinding head 54 with the corresponding roughness at different grinding stages. Combined with the adaptive adjustment component 4 for dynamic adjustment of the grinding component 5 and the sensor component 45 for real-time monitoring of the seat ring surface, it ensures that the grinding head 54 is always in the most suitable state to fit the seat ring surface, thereby achieving high-precision grinding of the pumped storage turbine seat ring 1 from roughing to finishing, and ensuring the processing quality of the seat ring.

[0080] The specific working principle of this utility model's rotary pumped storage turbine base ring on-site grinding equipment is as follows:

[0081] First, the pumped storage turbine seat ring 1 to be ground is placed stably on the horizontal placement surface of the placement base 2 located on the construction site using hoisting equipment. The stable support structure of the placement base 2 ensures that the seat ring remains stable throughout the grinding process. Before placement, the rotating base 42 in the adaptive adjustment component 4 can be rotated to move the vertical displacement component 44 and the grinding component 5 to avoid interfering with the hoisting of the seat ring. After placement, the rotating base 42 is reset, and the limiting pin 43 is inserted through the through hole between the connecting arm 41 and the rotating base 42 to fix its position.

[0082] Next, the rotary drive assembly 3 is activated, the outer gear ring 31 fixed on the outside of the placement base 2 remains stationary, and no fewer than two rotary displacement seats 32 are engaged with the outer slide rail of the placement base 2 through sliding parts, and can rotate around the seat ring. The drive motor 33 on the surface of the rotary displacement seat 32 is turned on, and the gear 34 at its output end meshes with the outer gear ring 31 and rotates, driving the rotary displacement seat 32 to make a circular motion around the seat ring, thereby driving the adaptive adjustment assembly 4 and the grinding assembly 5 installed on it to rotate synchronously.

[0083] During the polishing process, the laser displacement sensor 452 pre-scans the contour of the surface to be polished on the seat ring before polishing, measures the distance between the seat ring and the surface of the mounting base 451 and compares it with the preset polishing value to change the position of the polishing component 5; the six-dimensional force sensor 453 at the moving end of the vertical displacement component 44 monitors the magnitude and direction of the contact force between the polishing component 5 and the seat ring in real time. When the laser displacement sensor 452 detects deviations such as concavity of the seat ring surface, it transmits the displacement data to the control system, driving the vertical displacement component 44 to adjust the feed of the polishing component 5, such as increasing the pressure and decreasing or increasing the rotation speed; if the six-dimensional force sensor 453 reports abnormal local contact force, the control system synchronously adjusts the rotation speed of the polishing motor 52 and the pressure of the polishing component 5 to ensure that the polishing head 54 fits the actual curved surface of the seat ring and avoids over-cutting or under-cutting;

[0084] According to the requirements of the grinding stage, the grinding head 54 is replaced by the quick-release component 53. During installation, the limiting ring 536 is moved away from the limiting ring 537, and the elastic element 535 is in a compressed state. The grinding head 54 connected to the quick-release component 532 is pushed in along the axis of the quick-release seat 531. Then the limiting ring 536 is released, and the elastic element 535 drives the limiting ring 536 to return to its original state. After being compressed, the limiting bead 533 is embedded in the limiting annular groove 534 of the quick-release component 532. The limiting ring is then tightened. Ring 537 is threadedly connected to limiting ring 536 to lock the position of limiting ring 536; during disassembly, the limiting ring 537 is rotated in the opposite direction to push the limiting ring 536 to compress the elastic element 535, so that the limiting bead 533 is disengaged from the limiting annular groove 534, and the grinding head 54 can be removed by pulling out the quick release piece 532. In the initial stage of grinding, a high-roughness grinding head 54 is selected for roughing, in the middle stage, a medium-roughness grinding head is replaced for finer grinding, and in the later stage, a low-roughness grinding head is used for polishing to achieve high-precision grinding throughout the entire process;

[0085] At the same time, the air pump 6 inside the base 2 is started, and the dust generated by grinding at the dust collection hood 8 is sucked in through the air pipe 7 and transported to the filter component 9 for purification through the pipeline. The particle monitor 10 on the surface of the dust collection hood 8 detects the dust content in real time. When the concentration is lower than the set threshold, the air pump 6 is automatically shut off to ensure a clean working environment and the health of personnel. Finally, the efficient and high-precision grinding operation of the pumped storage turbine seat ring 1 is completed.

[0086] It should also be noted that the electrical equipment selected in this utility model are all commercially available models with no special requirements. In addition, the control system of the entire grinding device is a conventional technical means for those skilled in the art, and will not be described in detail here.
