Description

Technical Field

[0001] This utility model belongs to the field of steelmaking, and in particular relates to a tool for disconnecting an argon pipeline in case of an accident. Background Technology

[0002] A steel plant's ladle refining section is equipped with two 120t refining LF furnaces. Due to design limitations, the refining LF furnaces initially did not have emergency argon pipelines installed above the furnace covers. Therefore, argon gas was introduced into the molten steel ladle via a pipeline. When the argon flow in the molten steel ladle was insufficient during refining, manual connection and disconnection of the emergency argon pipeline was required. However, this manual connection and disconnection required ground personnel to climb up and down the ladle car to the bottom of the molten steel ladle, posing certain safety risks to the operators. Furthermore, the connection and disconnection of the emergency argon pipeline consumed production time, disrupting the production schedule. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a tool for disconnecting emergency argon lines, which can be used to disconnect emergency argon lines from the ground, avoiding the need for operators to frequently get on and off the steel car, improving the safety factor for operators, and saving time and effort.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A tool for disconnecting an emergency argon pipeline includes an extension rod and a bayonet. The end of the extension rod is fixedly connected to the bayonet, which has an arc-shaped plate structure and is compatible with the quick connector of the emergency argon pipeline.

[0006] The cross-section of the bayonet is semi-circular.

[0007] The inner diameter of the bayonet is a stepped arc structure with a protrusion in the middle.

[0008] The extension rod is divided into two sections, front and rear, which are hinged together. The front section is welded to the bayonet.

[0009] A light is fixedly connected to one end of the extension rod near the bayonet.

[0010] The extension rod is made of steel pipe.

[0011] The extension rod has a handle attached to the end furthest from the bayonet.

[0012] The front end of the extension rod is welded to the outer wall of the bayonet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The tool for disconnecting emergency argon lines has a simple and reasonable structure. The operator holds the extension rod on the ground, aligns the clamp with the quick-connect fitting of the emergency argon line, and pulls back to complete the disconnection. This avoids frequent loading and unloading of the steel carriage, improving operator safety and ensuring inherent safety. This invention shortens the operation time for disconnecting emergency argon lines and improves labor productivity. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings. However, it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0021] Example 1

[0022] See Figure 1 , Figure 2 A tool for disconnecting an emergency argon pipeline includes an extension rod 1 and a clamp 2. The end of the extension rod 1 is welded and fixed to the outer wall of the clamp 2. The clamp 2 is an arc-shaped plate structure that matches the quick connector of the emergency argon pipeline. The cross-section of the clamp 2 is semi-circular. The inner diameter of the clamp 2 is a stepped arc structure with a protruding center. If the end of the clamp 2 does not engage with the end of the quick connector, its protruding arc-shaped part can still engage with the end of the quick connector. Because the steps for getting on and off the ladle car are narrow, allowing only one person to pass at a time, and the area at the bottom of the molten steel tank is also confined, manually disconnecting the emergency argon pipeline is difficult. However, by holding the extension rod 1 and hooking the clamp 2 onto the quick connector of the emergency argon pipeline, the argon disconnection operation can be completed by pulling back. This saves time and effort, reduces the frequency of personnel getting on and off the ladle car, and allows the emergency pipeline to be quickly disconnected while the ladle car is moving.

[0023] Example 2

[0024] See Figure 3The difference from Embodiment 1 lies in the use of a two-section extension rod 1, with the front and rear sections hinged together. This hinge can be achieved by connecting a universal joint 6. The front section is shorter, and the universal joint 6 is located near the bayonet 2. The front section is welded to the bayonet 2. If the extension rod 1 forms a certain angle with the quick connector of the emergency argon pipeline, the universal joint 6 can create an angle between the front and rear sections, allowing the bayonet 2 to fit snugly against the quick connector, facilitating operation.

[0025] Example 3

[0026] Due to the confined space and insufficient lighting at the quick-connect fitting of the argon pipeline in the accident, it was difficult for operators to observe the location of the quick-connect fitting. Figure 4 A lamp 3 is fixedly connected to the front end of the extension rod 1 to facilitate the operator aligning the bayonet 2 with the quick connector. A handle is attached to the rear end of the extension rod 1 for easy gripping. A rechargeable battery 4 can be installed inside the extension rod 1 to provide power to the lamp 3. A switch 5 is located at the rear end of the extension rod 1 for easy control of the lamp 3.

[0027] In actual production, the bayonet 2 can be made from the female end of a discarded quick connector. The female end is cut open, and a 180° semi-circular part is taken and welded to the end of the steel pipe at the outer wall. The extension rod 1 is made from a steel pipe. The extension rod 1 is made from a steel pipe with a diameter of 15mm and a length of 2m.

[0028] This invention features a simple and reasonable structure. The operator holds the extension rod 1 on the ground, aligns the clamp 2 with the quick connector of the emergency argon pipeline, and pulls it back to complete the argon removal operation. This avoids the operator frequently getting on and off the steel cart, improving operator safety and ensuring inherent safety. This invention also shortens the operation time for removing emergency argon pipelines, improving labor productivity.

[0029] Through the above specific embodiments, those skilled in the art can easily implement this utility model. However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions. Due to space limitations and for the sake of brevity, not all of these combined solutions have been described. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
