[0040] Embodiment 2

[0041] This embodiment also provides a method for using the gas blower gas seal scraping tool as in the first embodiment, comprising the following steps:

[0042] 1. Preparation

[0043] First, check whether all parts of the tool are complete and firmly connected. Make sure that the rollers 1, grips 4, scrapers 8, fine-tuning devices and other parts on both sides of the bracket 2 are in normal condition.

[0044] 2. Installation and Adjustment

[0045] The two rollers 1 are attached to the gaps of the gas seal comb teeth of the gas blower. The grooves 101 of the rollers 1 are arranged correspondingly to the gas seal comb teeth, so that the tool can move stably on the inner wall of the gas seal by relying on the comb teeth.

[0046] The scraper 8 is moved by the fine adjustment device to adjust the relative position of the scraper 8 and the air seal. The differential cylinder 5 in the fine adjustment device is threadedly connected to the external thread cylinder 508, and the scraper 8 can be driven to move by rotating the differential cylinder 5. At the same time, the first scale 205 on the side wall of the bracket 2 and the scale and indicator line on the outside of the differential cylinder 5 are observed to accurately grasp the moving distance of the scraper 8, thereby accurately controlling the extension amount of the scraper 8, and then controlling the scraping amount.

[0047] 3. Scraping and grinding operation

[0048] Adjust the scraping scale according to the first scale 205 to ensure that the scraping amount meets the requirements.

[0049] Gripping the handle 4 causes the bracket 2 to move circumferentially in the air seal. During the movement, the rollers 1 on both sides of the bracket 2 ensure that the scraper 8 has a consistent scraping height without any height difference. The connecting frame 3 makes the connection between the handle 4 and the bracket 2 more flexible and can adapt to different operating angles. Even if the operator shakes the handle 4 during operation, the swingable design of the connecting frame 3 can eliminate the impact of such shaking on the scraper 8, ensuring that the height and angle of the scraper 8 relative to the comb teeth are correct.

[0050] The air seal reaches the required accuracy through multiple measurements of the scraping process. During the scraping process, the positioning pin 703; the first positioning hole; 704 ensures that the scraper 8 is fixed on the blade 7 to prevent the scraper 8 from shifting and ensure the scraping quality. The positioning sleeve 9 further fixes the position of the scraper 8 to improve the stability of the scraping. The design of the six-sided 902 is convenient for operation with a wrench, which is convenient for fine-tuning the position of the scraper 8.

[0051] In summary, the gas blower gas seal scraping tool is simple and easy to operate, and can accurately adjust the position and scraping amount of the scraper 8 to ensure the gas seal scraping accuracy and improve work efficiency.

[0052] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
