Technical Field
[0001] This utility model relates to the field of crystallizer maintenance technology, specifically a climbing tool that helps in the maintenance of crystallizers. Background Technology
[0002] The main function of a crystallizer is to cool and solidify liquid metal (such as molten steel) into a solid shell with a certain shape and size. Its working principle is based on heat exchange. Liquid metal is introduced into the crystallizer, and the crystallizer wall is usually made of a material with good thermal conductivity, such as copper, and has cooling channels.

This poses a significant safety hazard, is impractical, and fails to effectively protect workers. Therefore, we propose a climbing tool to address these issues and facilitate crystallizer maintenance. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-6 This utility model provides a technical solution: a climbing tool that helps in the maintenance of crystallizers, including a mounting frame 1 for installing the crystallizer, a maintenance platform 2 for workers to stand on fixedly connected to the top of the mounting frame 1, two fixed vertical plates 3 for fixing are fixedly connected to the front side of the mounting frame 1, a foot pedal 4 for support is fixedly connected between the two fixed vertical plates 3, guide grooves 5 for limiting the movement trajectory of the structure are opened on the front surface of the two fixed vertical plates 3, several connecting plates 6 for connecting are provided inside the guide grooves 5 on both sides, a support rod 7 for supporting the workers is fixedly connected between the two connecting plates 6, several rotating shafts 8 for connecting are rotatably connected inside the guide grooves 5, the outer surface of the rotating shafts 8 is fixedly sleeved on the connecting plates 6, and the connecting plates 6 and the support rods 7 can be moved by rotating the rotating shafts 8.
[0028] The fixed vertical plate 3 has a first cavity 9 inside. The end of the rotating shaft 8 near the first cavity 9 is rotatably inserted into the first cavity 9. The first cavity 9 is rotatably connected to a drive rod 10, which serves as a connection. The outer surface of the drive rod 10 is fixedly fitted with a first bevel gear 11 for transmission. The rotation of the two drive rods 10 can drive the first bevel gear 11 fixedly fitted on its surface to rotate. The end of the rotating shaft 8 located inside the first cavity 9 is fixedly fitted with a second bevel gear 12, which is also used for transmission. The rotation of the second bevel gear 12 can drive the rotating shaft 8 to rotate. The first bevel gear 11 and the second bevel gear 12 are meshed and connected. The rotation of the first bevel gear 11 can drive the rotation of the second bevel gear 12. The bottom horizontal plate of the mounting bracket 1 has a second cavity 13 inside. The second cavity 13 is equipped with a drive assembly.
[0029] The drive assembly includes a support shaft 17 that provides support. The support shaft 17 is rotatably connected inside the second cavity 13. A first gear 18 that provides transmission is fixedly sleeved on the outer surface of the support shaft 17. The rotation of the support shaft 17 can drive the rotation of the first gear 18.
[0030] The lower ends of both drive rods 10 rotate through the interior of the second cavity 13. One end of each drive rod 10 located inside the second cavity 13 is fixedly fitted with a synchronous pulley 14 for transmission. The two synchronous pulleys 14 are externally meshed with a synchronous belt 15 to facilitate the synchronous rotation of the two synchronous pulleys 14. The rotation of the second gear 19 can drive the rotation of the left drive rod 10. At this time, with the cooperation of the two synchronous pulleys 14 and the synchronous belt 15, the right drive rod 10 will rotate synchronously.
[0031] The left drive rod 10 is fixedly fitted with a second gear 19 at one end inside the second cavity 13, which also serves as a transmission mechanism between the structures. The first gear 18 and the second gear 19 are meshed and connected, and the rotation of the first gear 18 can drive the rotation of the second gear 19.
[0032] A motor 16 is fixedly connected to the surface of the horizontal plate at the bottom of the mounting bracket 1. The output shaft of the motor 16 rotates through the interior of the second cavity 13 and is fixedly connected to the support shaft 17. The rotation of the output shaft of the motor 16 can drive the rotation of the support shaft 17.
[0033] Among them, motor 16 is a servo motor, which is existing technology. Also matched with motor 16 are power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail.
[0034] Both fixed vertical plates 3 are fixedly connected to handles 20 for easy gripping by workers. The handles 20 effectively improve the efficiency of workers when climbing.
[0035] The receiving rod 7 is fitted with a buffer pad 701 that serves to transmit impact. The buffer pad 701 can provide a certain buffer when the worker comes into contact with the receiving rod 7, thereby effectively reducing the pain when the receiving rod 7 comes into contact with the worker.
[0036] The top of the mounting frame 1 is fixedly connected to a protective barrier 21, which further improves the safety of the staff.
[0037] Working principle:
[0038] When using this climbing tool that aids in crystallizer maintenance, the motor 16 is activated by turning on its switch. The rotation of the motor 16's output shaft drives the support shaft 17, which in turn drives the first gear 18, which in turn drives the second gear 19. The second gear 19 then drives the left drive rod 10. Simultaneously, with the cooperation of the two synchronous pulleys 14 and the synchronous belt 15, the right drive rod 10 rotates synchronously. The rotation of both drive rods 10 drives the first bevel gear 11, which is fixedly mounted on its surface, to rotate. The rotation of the first bevel gear 11 drives the second bevel gear 12, which in turn drives the rotating shaft 8. The rotation of the rotating shaft 8 then moves the connecting plate 6 and the supporting rod 7, ultimately making the connecting plate 6 perpendicular to the fixed vertical plate 3.
[0039] Then, the staff can enter from the bottom between the receiving rod 7 and the mounting frame 1. When climbing, they can hold the handle 20 and climb to the top of the maintenance platform 2 by stepping on the pedal 4, and then carry out maintenance on the crystallizer.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
