Description

Technical Field

[0001] The invention relates to the application field of segment embedded parts, and in particular to an oxidation layer removal mechanism for shield segment embedded parts. Background Art

[0002] A shield segment is a structural component used in shield tunnel construction. It is usually made of reinforced concrete and is ring-shaped. It is used to support and protect the tunnel. During the shield tunnel excavation process, the shield segment is gradually installed on the tunnel wall through the advancement of the shield machine to form the tunnel structure.

[0003] The connection between shield segments is usually achieved through metal parts. These metal parts can be pre-embedded during the manufacturing process of the segments or installed on-site. The metal parts installed on-site need to be installed through holes and then filled with cement. The purpose of using metal embedded parts is to ensure that the connection between the segments is firm and safe during tunnel construction and later use. Common metal embedded parts include threaded sleeves, steel rings, steel plates and steel sheets.

[0004] In actual applications, if workers use the method of on-site installation of metal embedded parts, they need to treat the oxide layer on the surface of the metal parts through on-site cleaning, grinding, coating of anti-corrosion layer and other methods. Removing the oxide layer can ensure the quality of subsequent fastening, ensure the quality of welding or connection, and improve waterproofness. Taking the threaded sleeve as an example, workers usually use a manual grinder or a pipe grinder for grinding. Manual grinding is less efficient, and both grinding methods will produce more metal debris, causing greater harm to the human body. Some metal embedded parts will also rust on the surface due to long storage time, and the loose rusted part will make grinding difficult. Summary of the Invention

The transmission mechanism 25 can ensure that the threaded sleeve can still rotate when moving between the scraper 16 and the grinding wheel 9, and the second spring 2504 of the transmission mechanism 25 is a high-strength spring, so that the top pressing conical head 2506 can effectively support the threaded sleeve, and the outer wall of the top pressing conical head 2506 is frosted to increase friction, so that the rotation of the top pressing conical head 2506 can more stably drive the threaded sleeve to rotate.

[0048] In the above embodiment, please refer to Figure 2 , multiple groups of snap-fit ​​frames 14 are provided on the inner wall of the outer cylinder 12, and scrapers 16 are installed in the multiple groups of snap-fit ​​frames 14, multiple groups of moving components 17 are provided, and fixed components 18 are provided on the top of the multiple groups of moving components 17, and the multiple groups of moving components 17 correspond to the multiple groups of scrapers 16, and multiple groups of mounting grooves 21 are provided on the top of the supporting plate 20, and transmission mechanisms 25 are installed in the multiple groups of mounting grooves 21, and the multiple groups of transmission mechanisms 25 correspond to the multiple groups of fixed components 18. By arranging multiple groups of scrapers 16, moving components 17, fixed components 18 and transmission mechanisms 25, the grinding equipment can grind multiple groups of threaded sleeves at a time.

[0049] In the above embodiment, please refer to Figure 4Two sets of collecting cabins 26 are movably installed on the top of the equipment base 1 outside the first cylinder 2, and the two sets of collecting cabins 26 are symmetrically arranged. The collecting cabins 26 are semi-arc-shaped, and the two sets of collecting cabins 26 are located at the bottom of the extension frame 11. By setting two sets of semi-arc-shaped collecting cabins 26, metal debris dropped during grinding can be collected to avoid metal debris polluting the environment.

[0050] During the specific operation of the present invention: when the staff needs to grind a batch of threaded sleeves, the staff first installs and sleeves multiple threaded sleeves on the top of multiple groups of fixed components 18, and sleeves the threaded holes at the bottom of the threaded sleeves on the outside of the two groups of columns 1807, and ensures that the threaded sleeves and the tops of the two groups of sliding blocks 1804 fit together. Then the staff uses the cylinder cover 19 to cover the outer cylinder 12. After the cylinder cover 19 is closed, the pressing conical heads 2506 of the multiple groups of transmission mechanisms 25 in the cylinder cover 19 will align with the threaded holes on the tops of the compressed threaded sleeves, and the pressing conical heads 2506 will drive the fixed rod 2505 and the movable tube 2503 to rise, and then the rising of the movable tube 2503 will compress the second spring 2504, and at the same time, the rising of the fixed rod 2505 will slide along the outer wall of the second square rod 2509, and the pressing conical heads 2506 will press the second spring 2504. Under the resetting action, it will firmly support the threaded sleeve. At this time, the first driving device 7 is started to drive the inner cylinder 5 to rotate, and the inner cylinder 5 will drive the first face gear 6 to rotate, and then the first face gear 6 will drive the first transmission gear 1703 of the multiple groups of moving components 17 to rotate, and the first transmission gear 1703 drives the threaded rod 1702 to rotate, thereby controlling the movement of the moving seat 1705 to drive the fixed component 18 and the threaded sleeve sleeve on its top to move toward the scraper 16 until the surface of the threaded sleeve fits the scraper 16. In the process of the moving seat 1705 driving the fixed component 18 and the threaded sleeve sleeve on its top to move, the movement of the threaded sleeve will also synchronously drive the top pressure cone head 2506, the fixed rod 2505, the second spring 2504, the movable tube 2503, the bearing seat 2501 and other structures to move, so that the sleeve 2511 is located on the outside of the third-shaped rod 2515 and slides.

[0051] After the threaded sleeve fits the scraper 16, the first driving device 7 is turned off and the second driving device 8 is started to drive the grinding wheel 9 to rotate. Here, the speed of the grinding wheel 9 does not need to be too high. The rotation of the grinding wheel 9 will drive the first square rod 10 to rotate, and then the first square rod 10 cooperates with the round rod 22 through the square groove 23. The first square rod 10 drives the round rod 22 to rotate, and the rotation of the round rod 22 drives the second face gear 24 to rotate. The second face gear 24 drives the second transmission gear 2514 of the multi-group transmission mechanism 25 to rotate. When the second transmission gear 2514 rotates, it drives the third shaped rod 2515 to rotate, and then the third shaped rod 2515 The sleeve 2511 and the second bevel gear 2512 are driven to rotate, and the second bevel gear 2512 is engaged with the first bevel gear 2508. The second square rod 2509 drives the fixed rod 2505 to rotate, and then the fixed rod 2505 drives the top-pressing conical head 2506 to rotate. Since the top-pressing conical head 2506 presses against the threaded hole at the top of the threaded sleeve, the fixed assembly 18 and the threaded sleeve rotate synchronously with the top-pressing conical head 2506. When the threaded sleeve rotates, it scrapes against the scraper 16 to remove loose rust on the surface of the threaded sleeve. The scraped rust falls to the top of the conical cylinder cover 4 and then slides into the collection cabin 26 to be collected.

[0052] The rust on the surface of the threaded sleeve is scraped off and polished after a period of time, and then the second driving device 8 is stopped according to the above steps, and then the first driving device 7 is started to adjust the moving component 17, so that the threaded sleeve moves to fit with the grinding wheel 9, and the second driving device 8 is started in the same way to drive the grinding wheel 9 to rotate. At this time, the threaded sleeve will also rotate. The grinding wheel 9 rotates and further polishes multiple groups of threaded sleeves at the same time, so that the surface grinding accuracy of the threaded sleeve is higher.

[0053] The moving assembly 17 drives the threaded sleeve to move and fit the scraper 16 or the grinding wheel 9. A sensor can be set inside the device for precise control, such as a distance sensor (the existing technology will not be described in detail here).

[0054] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
