Description

Technical Field

[0001] This invention relates to the field of steam turbine rotor maintenance technology, and in particular to a special device for driving steam turbine rotor displacement. Background Technology

[0002] In power plant equipment, steam turbines are a commonly used large-scale device, and steam turbine units are all large-capacity. As the unit capacity increases, the volume and weight of the steam turbine rotor also increase significantly. Steam turbine rotor displacement inspection is an extremely important task. Rotor maintenance requires moving the entire shaft system, cleaning and inspecting for surface damage and metal flaws in a timely manner, and conducting a comprehensive circumferential inspection to avoid damage and defects that could lead to abnormal steam turbine operation and affect work efficiency.

[0003] In existing technologies, the conventional method is to use jacks to rotate and move the rotor on both sides to achieve the purpose of alternately pushing the rotor to both sides. However, the pushing force and pushing distance of the jacks cannot be effectively controlled, which can easily lead to excessive force, excessive stress on the bearings and deformation, and excessive pushing distance of the rotor can cause it to fall, posing a risk of damaging the equipment and endangering the personal safety of the staff. Based on this, we have proposed a special device for the displacement and pushing of steam turbine rotors. Summary of the Invention

[0005] In view of the problems of existing turbine rotor displacement pushing devices that use jacks to rotate and move the rotor on both sides to achieve the purpose of alternately pushing the rotor to both sides, the pushing force and pushing distance of the jacks cannot be effectively controlled, and it is easy to use excessive force, causing excessive stress on the bearing and deformation, and also causing the rotor to fall due to excessive pushing distance, which poses risks of damaging equipment and endangering the personal safety of workers. Therefore, this invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a special device for driving the displacement of a steam turbine rotor, which aims to improve the stability and safety of the movement of the steam turbine rotor, improve the maintenance quality of the unit, and reduce the risk of equipment damage and the cost of damage repair.

[0033] Example 1

[0034] Reference Figures 1-3This invention provides a special device for displacing a steam turbine rotor, comprising a fixing mechanism 100, including a fixing component 101, a limiting component 102 disposed on the fixing component 101, two sets of driving components 103 symmetrically disposed within the limiting component 102, and two sets of clamping components 104 symmetrically disposed on one side of the limiting component 102. The fixing mechanism 100 is made entirely of metal, is hard, and has a long service life. The limiting component 102 and the fixing component 101 are integrally fixed structures. The driving components 103 are rotatably disposed on the limiting component 102. The clamping components 104 are used to clamp the steam turbine rotor. Compared with conventional bolts lifting the rotor, the contact surface between the clamping components 104 and the rotor is larger, which can prevent damage to the outer surface of the rotor.

[0035] During use, the end of the clamping component 104 is engaged and slidably mounted on the limiting component 102, and the part engaged in the limiting component 102 is threadedly connected to the driving component 103. When the driving component 103 rotates, the clamping component 104 slides along the direction of the limiting component 102 through the threaded connection with the driving component 103 and the engagement and limiting of the limiting component 102. The clamping components 104 on both sides move synchronously, thereby realizing the function of clamping and fixing the turbine rotor.

[0036] The adjustment mechanism 200 includes a transmission component 201 located at the center of the fixed component 101, an adjustment component 202 disposed on the transmission component 201, a hand crank 203 disposed at the top of the transmission component 201, and a connecting component 204 inserted into the hand crank 203. The transmission component 201 is rotatably connected to the fixed component 101, the hand crank 203 is fixedly connected to the transmission component 201, the adjustment component 202 is sleeved on the transmission component 201, and the transmission component 201 and the adjustment component 202 can be inserted and fixed together by the connecting component 204. The connecting component 204 is slidably connected inside the hand crank 203 and extends to the top of the transmission component 201.

[0037] During use, the transmission component 201 meshes with the inner end of the drive component 103, causing the drive component 103 to rotate. By rotating the handwheel 203, the transmission component 201 is driven to rotate. At this time, the transmission component 201 will drive the drive components 103 on both sides to rotate in different directions, thereby pushing the clamping component 104 to move inward or outward synchronously. By connecting the transmission component 201 and the adjustment component 202 through the connecting component 204, the purpose of the transmission component 201 driving the adjustment component 202 to rotate can be achieved.

[0038] Example 2

[0039] Reference Figures 1-3This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that by controlling the moving direction and distance of the clamping component 104, the function of clamping rotors of different sizes can be realized, thereby accurately controlling the displacement distance and force of the rotor and preventing the problem of excessive pushing and rotor falling off.

[0040] Compared to Embodiment 1, the fixing component 101 further includes a fixing plate 101a located at the bottom, a mounting bracket 101b located at the center above the fixing plate 101a, and a partition 101c located inside the mounting bracket 101b. The 101a has fixing holes 101a-1 for fixing, and the fixing mechanism 100 can be fixed to the steam turbine as a whole by bolts engaging with the fixing holes 101a-1. The mounting bracket 101b is located at the center of the fixing plate 101a and divides the fixing plate 101a into equal parts. The partition 101c is used to separate the space inside the mounting bracket 101b.

[0041] The limiting component 102 includes a guide rail 102a located above the fixing plate 101a and symmetrically distributed on both sides of the mounting bracket 101b, a limiting plate 102b disposed on the fixing plate 101a and located on one side of the guide rail 102a, and a groove 102c located between the guide rail 102a and the limiting plate 102b.

[0042] During use, the guide rail 102a and the limiting plate 102b have the same structure and are arranged parallel to each other on the fixed component 101. The gap between them is the slide groove 102c. The driving component 103 is arranged in the slide groove 102c. The top edge of the guide rail 102a has an arc-shaped structure, which facilitates the sliding of the clamping component 104 on it and reduces sliding resistance.

[0043] The driving component 103 includes a threaded rod 103a symmetrically arranged in the slide groove 102c, a connecting component 103b disposed at the innermost end of the threaded rod 103a, and a return spring 103c sleeved on the connecting component 103b and located between the threaded rod 103a and the connecting component 103b. The two ends of the threaded rod 103a are rotatably connected to the fixing component 101, and the inner end of the threaded rod 103a is rotatably connected to both sides of the mounting bracket 101b. The return spring 103c pushes the connecting component 103b outward from the inner end of the threaded rod 103a.

[0044] The inner end of the threaded rod 103a is fixedly connected to a connecting shaft 103a-1, and the connecting shaft 103a-1 is rotatably connected to both sides of the mounting bracket 101b. A storage groove 103a-2 is provided in the connecting shaft 103a-1. The connecting component 103b extends into the storage groove 103a-2. The connecting component 103b includes a rectangular telescopic rod 103b-1 with a rectangular structure, a driven bevel gear 103b-2 set at the top of the rectangular telescopic rod 103b-1, and a limiting piece 103b-3 set at the end of the rectangular telescopic rod 103b-1. The end of the rectangular telescopic rod 103b-1 extends into the storage groove 103a-2 and slides within the inner end of the threaded rod 103a by the limiting piece 103b-3. The rectangular structure ensures that the rectangular telescopic rod 103b-1 can extend and retract within the threaded rod 103a while also driving it to rotate.

[0045] The clamping component 104 includes a clamping plate 104a whose end is engaged with the guide rail 102a, and a buffer pad 104b disposed inside the clamping plate 104a. A threaded rod 103a passes through the end of the clamping plate 104a. The clamping plate 104a is engaged with the guide rail 102a, and a portion of its end extends into the slide groove 102c. One end extending into the slide groove 102c is threadedly connected to the threaded rod 103a. The clamping plate 104a is limited by the guide rail 102a and the limiting plate 102b, and can only slide horizontally on it. The buffer pad 104b changes the traditional rigid clamping of the bolt and the rotor into an elastic buffer clamping, which can avoid excessive clamping force and damage to the outer wall of the rotor.

[0046] During use, the reset springs 103c on both sides of the device push the connecting assembly 103b outward, causing the driven bevel gear 103b-2 to mesh with the transmission component 201, as shown in Figure 7. This allows both driving components 103 on both sides to connect with the transmission component 201. When the transmission component 201 rotates, the driving component 103 on the left rotates in the opposite direction to the transmission component 201, while the clamping component 104 on the right rotates in the same direction as the transmission component 201. This causes the clamping components 104 on both sides to be driven by the driving component 103 and move in opposite directions along the slide groove 102c, thereby achieving the function of clamping and releasing the turbine rotor. The direction of movement of the two sets of clamping components 104 is controlled by the number of rotations of the transmission component 201, and the rotation can be adjusted according to the actual size of the turbine rotor, thereby achieving the function of clamping and fixing turbine rotors of different sizes.

[0047] The remaining structure is the same as that in Example 1.

[0048] Example 3

[0049] Reference Figures 4-9This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the rotor clamped and fixed by the fixing mechanism 100 can be freely manipulated to move in any horizontal direction simply by turning the hand crank 203, making the rotor displacement and pushing work easier and faster.

[0050] Compared to Embodiment 2, the transmission component 201 further includes a drive bevel gear 201a located in the mounting bracket 101b, a limiting block 201b disposed below the drive bevel gear 201a, and a rotating shaft 201c disposed above the drive bevel gear 201a. The drive bevel gear 201a is rotatably connected to the fixed component 101 by the limiting block 201b. Both sides of the drive bevel gear 201a mesh with the drive component 103 under normal conditions. Two sets of limiting rings 201c-1 are provided on the rotating shaft 201c. The adjusting component 202 is sleeved between the two sets of limiting rings 201c-1. At the same time, a slot 201c-2 is opened on the rotating shaft 201c, and the connecting component 204 can be inserted into the slot 201c-2.

[0051] The adjusting component 202 includes a threaded sleeve 202a disposed on the rotating shaft 201c, a first adjusting component 202b disposed on one side of the threaded sleeve 202a, and a second adjusting component 202c disposed on the other side of the threaded sleeve 202a. The threaded sleeve 202a is sleeved between the limiting rings 201c-1, and a slot 202a-1 is provided on the inner side of the threaded sleeve 202a. The first adjusting component 202b and the second adjusting component 202c are rotatably threadedly connected to the two sides of the threaded sleeve 202a. The connecting component 204 includes a connecting rod 204a inserted into the hand crank 203, and an insertion plate 204b disposed below the connecting rod 204a. The connecting rod 204a is slidably inserted into the hand crank 203.

[0052] During use, the plug plate 204b is fixedly connected to the connecting rod 204a. In its normal state, the plug plate 204b is located above the slot 201c-2. At this time, the threaded sleeve 202a is fitted onto the rotating shaft 201c and will not rotate with it. When the plug plate 204b is pressed down by the connecting rod 204a, the plug plate 204b will be inserted into the slot 202a-1 through the slot 201c-2, thereby connecting the threaded sleeve 202a to the rotating shaft 201c. This allows the transmission component 201 to rotate while the adjustment component 202 rotates as a whole.

[0053] The first adjustment component 202b includes a first connecting shaft 202b-1 located on one side of the adjustment component 202, a first adjusting bevel gear 202b-2 disposed at the end of the first connecting shaft 202b-1, a first support spring 202b-3 sleeved on the first connecting shaft 202b-1, a first plug-in bracket 202b-4 disposed at the top of the side wall of the first connecting shaft 202b-1, and a first connecting nut 202b-5 disposed at the upper position inside the first plug-in bracket 202b-4.

[0054] The first support spring 202b-3 is located between the first connecting shaft 202b-1 and the partition 101c, lifting and fixing the first adjusting assembly 202b above the partition 101c. This prevents the first adjusting bevel gear 202b-2 from engaging with the driving bevel gear 201a. The distance between the first insertion brackets 202b-4 is greater than the diameter of the threaded sleeve 202a, so the first insertion brackets 202b-4 are not blocked or limited by the threaded sleeve 202a when moving. The first adjusting assembly 202b is threadedly connected to the threaded sleeve 202a via the first connecting nut 202b-5.

[0055] The second adjustment component 202c includes a second connecting shaft 202c-1 located on one side of the adjustment component 202, a second adjusting gear 202c-2 disposed at the end of the second connecting shaft 202c-1, a second support spring 202c-3 sleeved on the second connecting shaft 202c-1, a second plug-in bracket 202c-4 disposed at the top of the side wall of the second connecting shaft 202c-1, and a second connecting nut 202c-5 disposed at a lower position inside the second plug-in bracket 202c-4.

[0056] The first adjusting component 202b and the second adjusting component 202c have basically the same structure and the same principle. The special feature is that the first connecting nut 202b-5 and the second connecting nut 202c-5 are respectively located above the first plug-in bracket 202b-4 and below the second plug-in bracket 202c-4, so that when the two are connected to the threaded sleeve 202a, there is a certain space between them. At the same time, the first plug-in bracket 202b-4 and the second plug-in bracket 202c-4 are staggered. Through the staggered arrangement and the space between the first connecting nut 202b-5 and the second connecting nut 202c-5, the two will not obstruct each other when moving in relative directions.

[0057] During use, when the device performs the turbine rotor displacement driving operation, it can be divided into three states according to the driving direction of the device. During this process, the teeth of the driving bevel gear 201a mesh with the first adjusting component 202b, the second adjusting component 202c and the driven bevel gear 103b-2. After precise calculation, they will mesh together perfectly and there will be no misalignment.

[0058] State 1, such as Figure 7 As shown, the turbine rotor is clamped and fixed to facilitate subsequent pushing and displacement operations. Rotating the hand crank 203 drives the transmission component 201 to rotate. At this time, the driving bevel gear 201a meshes with the driven bevel gears 103b-2 on both sides, while the first adjusting bevel gear 202b-2 and the second adjusting gear 202c-2 do not contact each other. At this time, the transmission component 201 will drive the driving components 103 on both sides to rotate as a whole. The driving component 103 on the left side will rotate in the opposite direction to the transmission component 201, while the driving component 103 on the right side will rotate in the same direction as the transmission component 201, thereby driving the two sets of clamping components 104 to clamp the turbine rotor.

[0059] State 2, such as Figure 8 As shown, the turbine rotor is pushed to one side for a side inspection. At this time, the connecting component 204 is pressed, and it connects the threaded sleeve 202a to the transmission component 201 via the plug plate 204b. As the handwheel 203 continues to rotate, the first adjusting component 202b on the left side is threadedly connected to the threaded sleeve 202a via the first connecting nut 202b-5, sliding downwards and compressing the first support spring 202b-3. As the first adjusting component 202b moves downwards, the first adjusting bevel gear 202b-2 presses against the driven bevel gear 103b-2, causing the connecting component 103b to retract backwards. The moving bevel gear 103b-2 no longer contacts the driving bevel gear 201a, while the two sides of the first adjusting bevel gear 202b-2 will mesh with the driving bevel gear 201a and the driven bevel gear 103b-2 respectively. At this time, the first adjusting bevel gear 202b-2 will reverse the direction of rotation of the driven bevel gear 103b-2, so that the driving components 103 on both sides will rotate in the same direction, thereby achieving the purpose of pushing the turbine rotor in one direction. During this process, the first adjusting component 202b moves downward and the second adjusting component 202c moves linearly. The two will not obstruct each other through the staggered first plug-in frame 202b-4 and second plug-in frame 202c-4.

[0060] State 3, such as Figure 9As shown, the principle is the same as in state 2, except that the hand crank 203 is rotated in the opposite direction. At this time, the second adjusting component 202c descends and the first adjusting component 202b rises. In the same way, the driving components 103 on both sides are still in the same direction of rotation, which facilitates the horizontal pushing of the turbine rotor. When reset is required, the turbine rotor is pushed to the initial position. At this time, the first adjusting component 202b and the second adjusting component 202c no longer press the driven bevel gears 103b-2 on both sides and are in the reset state. The driving components 103 on both sides are in contact with the driving bevel gear 201a. At this time, the connecting rod 204a is pulled upward so that the threaded sleeve 202a is no longer connected to the rotating shaft 201c and no longer pushes the adjusting component 202 to work. Continue to rotate the hand crank 203. At this time, the driving components 103 on both sides rotate in opposite directions, which can drive the clamping components 104 on both sides to move in opposite directions, thereby releasing the turbine rotor and realizing reset.

[0061] The remaining structure is the same as that in Example 2.
