[0002] As an important means of peak load regulation for power grids, the maintenance cost of core components of gas turbines is high, and the maintenance technology has long been monopolized by foreign countries. Taking the GE 9F gas turbine as an example, the axial displacement problem of the R17 moving blades of its compressor is serious. The existing dismantling method mainly relies on manual labor and temporary tools. At present, it can only be temporarily assembled by relying on manpower and on-site tools.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1 , this embodiment provides a guiding mechanism.

[0030] The cooperation between the guide arc plate 100 and the moving part 200 can adjust the force direction of the guide as a whole, so as to adapt to the subsequent blade disassembly work.

[0031] The guide arc plate 100 is made of high-strength aluminum alloy material with good thermal conductivity and wear resistance. A track 103 is fixedly provided at the bottom thereof to ensure that the moving part 200 slides smoothly on the guide arc plate 100. The track 103 is made of wear-resistant material, such as polytetrafluoroethylene PTFE, to improve wear resistance and reduce friction coefficient.

[0032] The moving member 200 is made of a light and high-strength material, such as carbon fiber reinforced plastic CFRP, to reduce the overall weight and increase the moving speed. A driving wheel 202 is provided on one side of the moving member 200, and the driving wheel 202 can cooperate with the track 103 and can slide smoothly along the guide arc plate 100.

[0033] One side of the moving part 200 is connected to the operating module 201 through any wire or soft wire, and the operating module 201 can directly control the operation of the moving part 200. A driving part such as a motor can be installed inside the moving part 200, which is directly connected to the driving wheel 202, so that the driving wheel 202 is used to cooperate with the operating module 201. When the staff is ready to pull the blade, the moving part 200 can be controlled to move along the guide arc plate 100 by starting the operating module 201.

[0034] The structure of the entire guide arc plate 100 can be set to a quarter arc shape to maximize the number of force points for blade removal. After the operation module 201 is started, the subsequent knocking rod 500 can be started synchronously to gradually knock the blades, driving the blades to be removed to gradually loosen from the frame under vibration. Compared with traditional methods, the disassembly efficiency is greatly improved.

[0035] Example 2

[0036] Reference Figures 1 to 3 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that

[0037] The support plate 101 is fixedly arranged at one end of the guide arc plate 100, and a stabilizing platform 102 is fixedly installed at the bottom of the support plate 101. A plurality of stabilizing bolts 102a are installed through the surface of the stabilizing platform 102 to ensure the firm installation of the stabilizing platform 102 and enhance the stability and impact resistance of the stabilizing platform 102. The stabilizing bolts 102a are made of high-strength bolts to improve the firmness and tensile strength of the connection.

[0038] The bottom of the other end of the guide arc plate 100 is fixedly connected to the stable platform 102, which ensures the stability of the overall structure and the guiding accuracy of the moving part 200.

[0039] The top of the moving member 200 is fixedly connected with an adapter 203, which ensures the stable and sliding fit between the moving member 200 and the top traction device. The moving member 200 can use a high-precision ball bearing to improve the rotational motion accuracy and reduce wear.

[0040] The adapter 203 may be a universal ring to connect with the subsequent conductive chain 300 . The setting of the universal ring can provide a maximum range for the pulling angle of the conductive chain 300 .

[0041] Example 3

[0042] Reference Figures 1 to 5 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0043] The conductive chain 300 is fixedly connected to the top of the adapter 203. A rotating member 302 is installed on the conductive chain 300. The rotating member 302 can be a device for adjusting the tension of the chain, such as a wrench hoist. The conductive chain 300 uses a high-strength chain to improve the load-bearing capacity and wear resistance. A transmission belt 303 is also provided between the conductive chain 300 and the clamping member 301. The transmission belt 303 can be a belt commonly used at the construction site, which can buffer the tension between the conductive chain 300 and the clamping member 301.

[0044] A disassembly claw 400 is fixedly provided at the front end of the clamping member 301, and a buffer block 401 is fixedly provided on the inner wall of the disassembly claw 400. The buffer block 401 can protect the disassembled part from damage and prevent the blade from being damaged by excessive force during installation and disassembly. The disassembly claw 400 is made of high-strength material, such as stainless steel, to improve wear resistance and corrosion resistance.

[0045] The knocking rod 500 is placed opposite to the disassembly claw 400, and the blade to be disassembled is located between the knocking rod 500 and the disassembly claw 400. A drive box 501 is fixedly arranged at the bottom of the knocking rod 500, and a starter 502 is fixedly connected to one side of the drive box 501. The drive box 501 can drive the knocking rod 500 to perform reciprocating telescopic pushing motion. After the staff operates the starter 502, the knocking rod 500 can start to move and perform moderate striking to drive the blade to be disassembled to initially move in the direction of the disassembly claw 400, thereby cooperating with the disassembly claw 400 to gradually take out the blade.

[0046] When the starter 502 and the operating module 201 start working, the construction personnel can install safety structures such as anti-drop ropes for the blades to be disassembled in advance to prevent the blades from being thrown out of control after being detached.

[0047] First, fix the stabilizing platform 102 on the center plane of the cylinder body and fix it with a stabilizing bolt 102a; fix the clamping member 301 and the disassembly claw 400 on the lower part of the blade to be removed, install a knocking rod 500 on the driving box 501 to confirm the impact position, connect one end of the transmission belt 303 to the tail of the clamping member 301, and the other end to the conductive chain 300, and then connect the other end of the conductive chain 300 to the adapter 203 on the moving member 200.

[0048] The specific position of the moving member 200 is adjusted by operating the module 201 to ensure that the force direction of the rotating member 302 is consistent with the displacement direction of the blade root of the blade to be removed. The starter 502 starts to work, so that the knocking rod 500 strikes the blade root at a constant speed, and at the same time tightens the rotating member 302 to gradually move the blade out of the rotor disk.

[0049] During the dismantling process, safety hanging structures such as hand-held anti-fall ropes are used to prevent the blades from suddenly flying out. The entire dismantling process can be completed by only two workers.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
