[0007] According to the above technical solution, the water bucket is installed below the lower water tank, and the water bucket is connected to the sprinkler head through a pipe.

[0008] According to the above technical solution, an electric push rod 1 is installed at the end of the support frame.

[0009] According to the above technical solution, a distance sensor is installed inside the clamping plate one, and an inner clamping plate one is installed inside the clamping plate one. The inner clamping plate one is a plate made of flexible material. A groove is provided inside the clamping plate one, and a guide rod is installed in the groove.

A gear is provided on one side of the tooth groove, and the gear is meshed with the tooth groove. The inner clamping plate two is movably connected to the inside.

[0010] According to the above technical solution, the cleaning component includes a roller brush, which is arranged in two parallel positions in the vertical direction. An electric push rod 2 is fixedly installed at one end of the central rod of the roller brush. An installation groove is provided on the opposite sides of the two roller brushes in the vertical direction. The installation groove passes through the side of the roller brush where it is located. An eddy current sensor is installed in the installation groove. An installation box is fixed to the outside of the end of the roller brush. The bearing in the installation box is connected to the second motor. A driving gear is fixedly connected to the output end of the second motor. The bearings on both sides of the driving gear are connected to a driven gear.

The connecting rod is fixedly connected to the center of bevel gear 1, and a chuck is riveted to the end of the connecting rod.

[0013] According to the above technical solution, the method for using the steam turbine blade clamping tool comprises the following steps: S1-1: Place the center of gravity of the blade on top of the support frame, with the raised portion of the support frame fitting into the inner curved surface of the blade; S1-2: The electric track is started, and the blade is transported toward the cleaning assembly. After the electric track stops, the clamping assembly is started to clamp the root of the blade. The lower surface of the clamping plate 1 is in contact with the upper surface of the blade, and the upper surface of the clamping plate 2 is in contact with the lower surface of the blade, so that the blade is firmly clamped between the two clamping plates. S1-3: The electric push rod 1 at the end of the support frame drives it to descend, and the electric push rod 2 causes the roller brush to extend a distance to brush the blades. After brushing is completed, the dryer starts to dry the surface of the blades; S1-4: After drying is completed, the eddy current sensor on the roller brush will detect the surface of the blade and feedback whether there are cracks through the control panel. If no cracks are found, the support frame will rise and support the blade after contacting it again, and the clamping assembly will be loosened. The blade will be driven out of the baffle area by the electric track to complete the cleaning process of the blade.

[0014] According to the above technical solution, the method for using the steam turbine blade clamping tool further includes the following steps: S2-1: If the eddy current sensor indicates a crack on the blade surface through the control panel, the support frame rises, the clamping assembly releases its clamping force, and the electric track drives the support frame to move multiple times. The eddy current sensor then provides feedback on the crack situation until it indicates no cracks. The approximate location of the crack on the blade is then located, and the electric track moves the blade to the outside of the shielding plate. S2-2: Since the thickness of the blade crack area cannot be directly determined, the thickness distinction point of the blade is set to H. Distance sensors are installed inside the clamping plates 1 and 2. When the two plates are brought closer together until they are in contact with the blade surface, the distance sensor reflects the blade thickness h. S2-21: When h is greater than or equal to H, it indicates that the cracked area of ​​the blade is located in a thicker part. In this case, the lower and upper surfaces of the clamping plates 1 and 2 are directly attached to the blade for clamping. The operator then removes the blade for subsequent processing. S2-22: When h is less than H, it means that the crack area of ​​the blade is located in a thinner part. At this time, the inner clamping plate 1 needs to be extended downward to contact and fit with the upper surface of the blade, and the inner clamping plate 2 needs to be extended upward to contact and fit with the lower surface of the blade, so that the clamping force of the blade is evenly distributed and stably clamped. At this time, the operator can perform subsequent maintenance on the blade.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) By providing a clamping assembly, different clamping methods are used for blades of different thicknesses, so that the thicker parts can be clamped stably while the thinner parts can be clamped stably and prevented from being damaged by excessive clamping force; (2) By providing a cleaning component, the turbine blades are cleaned before clamping to remove oil, dust, rust and other impurities on the blade surface, ensuring the precise fit between the blades and the rotor or stator ring, reducing assembly errors, and helping to improve the assembly quality of the entire unit; (3) By providing a rotating assembly, the rotor on which the turbine blades are installed is clamped and rotated, which greatly improves the efficiency of blade installation.

[0020] like Figure 3 As shown, an electric push rod 1 is installed at the connection end of the support frame 6 and the electric track 5. When the support frame 6 moves on the electric track 5, the support frame 6 can also be raised and lowered by the electric push rod 1; the curved surface of the blade is facing upward, and its center of gravity section is placed on the support frame 6, so that the convex part of the support frame 6 fits with the curved surface of the blade, and the curved parts at both ends of the blade fit with the baffle, so that the support frame 6 supports the blade.

[0021] like Figure 4 , 5 As shown, the clamping assembly 7 includes a positioning frame 71 and a lifting rod 79. The positioning frame 71 is fixedly connected to the inside of the clamping platform 1. The positioning frame 71 is a square frame structure, and a pin is passed through the middle of the horizontal frame located above it. The pin is fixedly connected to the middle of the lifting rod 79. The lifting rod 79 is a rod structure in which two horizontal bars are overlapped front and back and the two ends are connected to each other.

The clamping effect is released; the clamping plate 1 75 and the clamping plate 2 78 are 8 are both plates with curved surfaces, which provide the main structural support and force transmission, so that the blades can be stably clamped, and a pressure sensor is installed on one side of the contact surface between the two plates and the blades to reflect the clamping conditions of the two plates and the blades. The clamping assembly 7 has a simple structure, and the large opening and closing between the clamping plate 1 75 and the clamping plate 2 78 can achieve precise clamping and release of the blades; when the clamping plate 1 75 and the clamping plate 2 78 are in a large opening and closing, the support frame 6 can pass between the two without obstruction.

[0022] like Figure 6-8As shown, a distance sensor is installed inside the clamping plate 75, and an inner clamping plate 752 is installed inside the clamping plate 75. The inner clamping plate 752 is a plate made of flexible material, which can ensure good fit with the blade surface. A groove is opened inside the clamping plate 75, and a guide rod 751 is installed in the groove of the clamping plate 75. A connecting block 753 is movably connected to the guide rod 751. The connecting block 753 is welded to both sides of the inner clamping plate 752. A connecting column 754 is welded above the inner clamping plate 752. The connecting column 754 is a column structure with uniform tooth grooves on one side. The connecting column 754 is opened. A gear 755 is provided on the side with the tooth groove, and the gear 755 is meshed with the tooth groove; the middle part of the gear 755 is connected to the motor three, and the motor three is installed inside the clamping plate 1 75; after the motor three is started, the gear 755 will rotate, and at the same time, the tooth groove on the connecting column 754 is meshed with the gear 755 and then transmitted, so that the inner clamping plate 1 752 extends downward, and contacts with the blade surface through the inner clamping plate 1 752, which can prevent the clamping force from being too large and damaging the blade; the inner clamping plate 2 78 is movably connected to the inner clamping plate 2 781, and the clamping plate 2 78 has the same structure as the clamping plate 1 75.

[0023] like Figure 9 As shown, the cleaning assembly 13 includes a roller brush 131, which is arranged in two parallel positions in the vertical direction. One end of the central rod of the roller brush 131 is fixedly installed with an electric push rod 2, and a mounting groove 132 is provided on each opposite side of the roller brush 131 in the vertical direction. The mounting groove 132 runs through the side of the roller brush 131 where it is located, and an eddy current sensor is installed in the mounting groove 132. The outer side of the end of the roller brush 131 is fixed with a mounting box 12, and the bearing in the mounting box 12 is connected to the motor 2. The output end of the motor 2 is fixedly connected with a drive gear 134. The drive gear 134 The bearings on both sides are connected to driven gears 133, and the middle part of the driven gear 133 is connected to the two ends of the electric push rod on the roller brush 131 through a connecting rod; after the motor 2 is started, the driving gear 134 rotates, driving the two driven gears 133 to rotate, and the roller brush 131 rotates synchronously and brushes the blade surface between the two roller brushes 131. At the same time, the eddy current sensor will also approach the blade surface. When there are cracks or other defects on the blade surface, the path of the eddy current will be changed, causing the distribution of the eddy current to change, and then the eddy current sensor will convert it into an electrical signal and output it to the control board 9 for feedback.

[0024] like Figure 10As shown, a chuck 15 is installed above the clamping platform 1 for fixing the rotor connected to the blade. The bottom of the chuck 15 is fixedly connected to a rotating assembly 16. The rotating assembly 16 includes a bevel gear 161. The bevel gear 161 bearing is connected to the inside of the installation cabinet 3. The inside of the installation cabinet 3 is installed with a motor 1. The output end of the motor 1 is fixedly connected to a bevel gear 2 162. The bevel gear 161 is meshed with the bevel gear 2 162. The center of the bevel gear 161 is fixedly connected to a connecting rod 163. The connecting rod 163 is the center Hollow structure, the end of the connecting rod 163 is riveted with a chuck 15, the rotor is inserted into the center of the chuck 15, and the chuck 15 is tightened after adjusting the installation section of the rotor to be consistent with the height of the blade. The hollow part of the connecting rod 163 can meet the fixation of some longer rotors. After the rotor is positioned, when the blades are clamped, the driving motor 1 makes the bevel gear 2 162 drive the bevel gear 1 161 to rotate, and then the chuck 15 rotates. The rotation angle is set by setting the motor 1, and finally the installation of the blades around the rotor is completed.

[0025] The control board 9 is electrically connected to the motor 1, the motor 2, the motor 3, the electric track 5, the electric push rod 1, the electric push rod 2, the hydraulic rod 72, and the eddy current sensor.

[0026] Embodiment 1. In this embodiment, the center of gravity of the blade is placed above the support frame 6, so that the protrusion of the support frame 6 fits into the inner part of the curved surface of the blade, and the bending parts of the two ends of the blade are limited by the baffles on the support frame 6, so that the blade is placed flat on the support frame 6; the electric track 5 is started to transport the blade toward the cleaning component 13. When the camera detects that the clamping component 7 is at the end position of the blade, the electric track 5 stops and the clamping component 7 is started to clamp the root of the blade. Due to the thickness of the root area of ​​the turbine blade, the blade moves to the cleaning component 13. If the blade is thicker, the lower surface of the clamping plate 1 75 can be fitted with the upper surface of the blade, and the upper surface of the clamping plate 2 78 can be fitted with the lower surface of the blade, so that the blade is firmly clamped between the two clamping plates. At the same time, the electric push rod 1 at the end of the support frame 6 will drive it to descend, and the electric push rod 2 will extend the roller brush 131 for a distance and drive it to rotate through the motor 2 to brush the blade. The spray head 10 sprays the roller brush 131 with water transported in the water bucket 4. After brushing is completed, the dryer 11 is started to dry the surface of the blade. After drying is completed, the eddy current sensor on the roller brush 131 will detect the surface of the blade and feedback whether there are cracks through the control board 9. If no cracks appear, the support frame 6 will rise and support the blade after contacting the blade again, and the clamping assembly 7 will be loosened, and the blade will be driven out of the baffle 8 area through the electric track 5 to complete the cleaning process of the blade.

[0027] Embodiment 2, based on embodiment 1, if the eddy current sensor feeds back that there is a crack on the surface of the blade through the control board 9, in order to determine the specific location of the crack, the support frame 6 is raised, and the blade is supported after contacting with the blade again, and the clamping assembly 7 is released at the same time, and the electric track 5 will drive the support frame 6 to move a set distance multiple times, and feedback on the crack situation is again obtained through the eddy current sensor until the feedback shows that there is no crack. The approximate position of the crack on the blade can be locked. At this time, the blade is moved to the outside of the baffle 8 by the electric track 5, and the crack location is exposed on the clamping platform 1, and the end of the blade is clamped by the clamping assembly 7; Since the thickness of the area where the blade crack is located cannot be directly determined, the thickness distinction point value of the blade is set to H. Distance sensors are installed inside the clamping plate 1 75 and the clamping plate 2 78 so that when the two plates are continuously approached until they are in contact with the blade surface, the thickness h of the blade can be reflected by the distance sensor. When h is greater than or equal to H, it indicates that the cracked area of ​​the blade is located in a thicker part. In this case, the lower and upper surfaces of the clamping plate 1 75 and the clamping plate 2 78 are directly connected to the blade to perform a clamping operation. At this time, the operator can then carry out subsequent processing operations on the blade. When h is less than H, it means that the crack area of ​​the blade is located in a thinner part. At this time, the inner clamping plate 1 752 needs to be extended downward to contact and fit with the upper surface of the blade, and the inner clamping plate 2 781 needs to be extended upward to contact and fit with the lower surface of the blade, so that the blade can obtain a uniform clamping force distribution and be stably clamped. At this time, the operator can perform subsequent maintenance on the blade.

[0028] Embodiment 3. In this embodiment, it is necessary to connect and install the blade with the rotor. The center of gravity of the blade is placed on the support frame 6. The blade is moved to the side of the chuck 15 by the electric track 5. At this time, the rotor has been positioned on the chuck 15. The camera detects that the blade connection end stops when it moves to the side of the rotor, and the outer end of the blade is clamped again by the clamping assembly 7. Since the outer end of the blade is often thinner and more fragile, it is necessary to take into account the stability of the blade while not causing excessive clamping force on the blade during clamping. At this time, the inner clamping plate 1 752 in the clamping plate 1 75 is controlled to extend downward and fit with the upper surface of the blade, and the inner clamping plate 2 781 is extended upward and fit with the lower surface of the blade. At this time, the clamping plate provides the main clamping force. The two inner clamping plates can reduce the pressure concentration on the blade surface to avoid scratches or indentations. At this time, the operator connects and installs the blade with the rotor again, and rotates the chuck 15 at a set angle through the rotating assembly 16, so that all blades are installed on the rotor in sequence.

[0029] The above embodiments improve the cleaning and crack detection operations before blade clamping, realize different clamping methods for different thickness areas of the blade, greatly improve the clamping quality of the blade, and the blade clamping position can be freely set, making the overall tooling highly versatile and capable of realizing other processing operations on the blade.

9. A method for using a steam turbine blade clamping tool, using the steam turbine blade clamping tool according to claim 8, characterized in that: The steps include: S1-1: placing the center of gravity of the blade above the support frame (6), with the raised portion of the support frame (6) fitting into the inner portion of the curved surface of the blade; S1-2: The electric track (5) is started, and the blade is transported toward the cleaning assembly (13). After the electric track (5) stops, the clamping assembly (7) is started to clamp the root of the blade, and the lower surface of the clamping plate (75) is in contact with the upper surface of the blade, and the upper surface of the clamping plate (78) is in contact with the lower surface of the blade, so that the blade is firmly clamped between the two clamping plates; S1-3: The electric push rod 1 at the end of the support frame (6) drives it to descend, and the electric push rod 2 causes the roller brush (131) to extend a certain distance to brush the blades. After the brushing is completed, the dryer (11) is started to dry the surface of the blades; S1-4: After drying is completed, the eddy current sensor on the roller brush (131) detects the surface of the blade and provides feedback via the control panel (9) on whether there are cracks. If no cracks are found, the support frame (6) rises and contacts the blade again to support the blade, and the clamping assembly (7) is released to drive the blade out of the baffle (8) area via the electric track (5), thereby completing the cleaning process of the blade.

10. The method for using a steam turbine blade clamping tool according to claim 9, characterized in that: The following steps are also included: S2-1: If the eddy current sensor feedbacks through the control board (9) that there is a crack on the blade surface, the support frame (6) rises, the clamping assembly (7) releases the clamping, and the electric track (5) drives the support frame (6) to move multiple times, and feedback of the crack condition is obtained through the eddy current sensor until feedback that there is no crack, and then the approximate position of the crack on the blade is locked, and then the blade is moved to the outside of the shielding plate (8) through the electric track (5); S2-2: Since the thickness of the area where the blade crack is located cannot be directly determined, the thickness distinction point value of the blade is set to H. A distance sensor is installed inside the clamping plate 1 (75) and the clamping plate 2 (78). When the two plates are continuously moved closer until they are in contact with the surface of the blade, the thickness h of the blade is reflected by the distance sensor. S2-21: When h is greater than or equal to H, it indicates that the crack area of ​​the blade is located in a thicker part. At this time, the lower surface and upper surface of the clamping plate 1 (75) and the clamping plate 2 (78) are directly connected to the blade to perform a clamping operation. At this time, the operator can perform subsequent processing operations on the blade. S2-22: When h is less than H, it means that the crack area of ​​the blade is located in a thinner part. At this time, it is necessary to extend the inner clamping plate 1 (752) downward to contact and fit with the upper surface of the blade, and extend the inner clamping plate 2 (781) upward to contact and fit with the lower surface of the blade, so that the clamping force of the blade is evenly distributed and stably clamped. At this time, the operator can perform subsequent maintenance on the blade.
