Description

Technical Field

[0001] This utility model relates to the technical field of tools for disassembling and assembling water jackets of metallurgical furnace tuyeres, and in particular to a tool for quickly disassembling and assembling water jackets of metallurgical furnace spray gun tuyeres. Background Technology

[0002] During the production process of metallurgical furnaces, it is often necessary to inspect or replace the water jackets of key equipment such as spray guns and air nozzles. Traditional dismantling and installation methods are constrained by the production site, requiring not only the installation or hanging of hoisting equipment, but also a large number of maintenance personnel, which not only increases the labor cost of maintenance, but also reduces maintenance efficiency. The main reasons are as follows: ① The metallurgical furnace spray gun and tuyere area has multiple spray guns and water jackets installed, with circulating water pipes, air supply pipes, and maintenance instruments arranged vertically and horizontally. The site environment is complex and the space is confined. During maintenance work, operators need to enter the confined space to operate, which is difficult, inefficient, restricts visibility, and poses safety risks due to the difficulty of positioning and operation. ② It is difficult to quickly align the spray guns and tuyere water jackets for fastening. The horizontal distance between the tuyere and the furnace base plane is about 100-300mm, and the horizontal spacing between each tuyere water jacket is 300-500mm. Due to the confined space, maintenance personnel are unable to perform tasks such as hole installation and water jacket positioning and fastening. ③ Manual handling of metallurgical furnace spray guns and tuyere water jackets during dismantling and installation poses safety risks. The tuyere water jackets are made of copper and are not of a standard shape. During dismantling and installation, the water jackets need to be carried to a metallurgical furnace installation platform of about 1.5m-2.5m. During the handling process, they are prone to injury from falling objects and also affect installation efficiency.

[0003] Therefore, how to design a simple, easy-to-operate tool that can quickly disassemble and assemble the spray gun nozzle water jacket is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This utility model provides a quick disassembly and assembly tool for the water jacket of the tuyer's nozzle in a metallurgical furnace, solving the technical problem of difficult disassembly and assembly of the existing water jacket for the tuyer's nozzle in a metallurgical furnace.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a quick disassembly and assembly tool for the water jacket of the tuyeres of a metallurgical furnace spray gun, comprising: a chuck, a handle, and a fixing component.

[0006] The chuck has a rod hole in the middle and multiple fixing holes on the outer periphery of the rod hole; one end of the handle can be detachably inserted into the rod hole; there are multiple fixing members, which are respectively fixed in the multiple fixing holes, and the multiple fixing members can be detachably connected to the spray gun nozzle water sleeve, so that the spray gun nozzle water sleeve can be moved to a safe area while the handle is pulled.

[0007] The beneficial effects of this utility model are: it improves the structure of the traditional metallurgical furnace spray gun tuyer water sleeve disassembly and assembly tool. First, multiple fixing parts fixed on the chuck are detachably connected to the spray gun tuyer water sleeve. Then, the position of the spray gun tuyer water sleeve is moved by the hand lever. This allows for quick positioning and connection of the spray gun tuyer water sleeve in a confined space, thereby increasing the disassembly and assembly speed of the spray gun tuyer water sleeve.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes a bracket, a fixed slide rail, and a movable slide rail. The fixed slide rail is fixed to the bracket; one end of the movable slide rail is foldable and connected to one end of the fixed slide rail; the spray gun nozzle water sleeve slides sequentially on the fixed slide rail and the movable slide rail.

[0010] The further beneficial effect of adopting the above is that by sliding the spray gun nozzle water jacket on the fixed slide rail and the movable slide rail, the moving friction of the spray gun nozzle water jacket can be reduced, and the smoothness of the spray gun nozzle water jacket movement can be improved.

[0011] Furthermore, the length of the handle is 1000–3000 mm. Attached Figure Description
