Description

Technical Field

[0001] This utility model relates to a maintenance device, specifically a safety platform device for repairing water leakage at the water-cooled furnace opening of a converter. Background Technology

[0002] The water-cooled furnace mouth is one of the main supporting equipment in converter steelmaking. To prevent deformation of the furnace mouth during high-temperature operation and to facilitate the removal of slag, a water-cooled furnace mouth with forced cooling by circulating water is commonly used. During operation, this equipment must withstand the furnace gas temperature and drastic, frequent temperature changes to the maximum extent. Furthermore, when the traveling crane is handling molten iron and scrap steel, it inevitably collides with the surface of the water-cooled furnace mouth. Additionally, when cold steel forms on its surface, the furnace cleaning car will also cause collisions while cleaning the furnace mouth. Under these conditions, its service life is significantly affected, and problems such as water leakage may occur.

[0003] Currently, water leakage in the furnace mouth water tank is an extremely dangerous situation during converter smelting. Therefore, when water leakage occurs, it is usually repaired and welded in time. However, since the converter has just stopped and the temperature is extremely high, and there is a distance between the furnace and the platform in front of the furnace when it is tilted, scaffolding is usually erected as a platform for maintenance. However, it is difficult to set up the support points between the scaffolding and the furnace, the erection time is long, the labor intensity of the workers is high, and the personnel cannot avoid the overhead crane in time, which poses a major safety hazard. Moreover, the workers are working in the high temperature environment for a long time, which is not only labor-intensive, but also prolongs the maintenance time and is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and defects of the existing technology by providing a safe platform device for repairing water leakage at the water-cooled furnace opening of a converter. Using this device to repair the water-cooled furnace opening not only eliminates the need for scaffolding, greatly shortening the repair time, but also reduces the potential hazards caused by personnel not being able to avoid the work in time during hoisting, ensuring overall repair efficiency and safety, while also reducing the workload of the staff, making it more practical and convenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety platform device for repairing water leakage at the water-cooled furnace opening of a converter, comprising a platform body 2, an upper cover plate 1 welded to the upper end of the platform body 2, a lifting lug mechanism 4 provided at one end of the platform body 2, and a trunnion reinforcing plate 5 and a bottom plate connecting plate 6 installed on the side of the platform body 2, a side trunnion assembly 3 welded to the upper end of the trunnion reinforcing plate 5, the end of the side trunnion assembly 3 welded to the platform body 2, and a lower bottom plate 8 welded to the bottom end of the bottom plate connecting plate 6, and a door panel 7 provided on one side of the platform body 2.

[0006] Furthermore, the base plate connecting plate 6 is provided in at least two sets and is symmetrically arranged on both sides of the platform body 2.

[0007] Furthermore, the side trunnion assembly 3 includes a side trunnion post 31, one end of which is welded with a limiting baffle 33, and the other end of which is welded to the platform body 2, and a trunnion sleeve 32 is fitted on the side trunnion post 31.

[0008] Furthermore, the lifting lug mechanism 4 includes two lifting lug plates 41, one end of which is welded to the platform body 2, and a lifting lug shaft 42 is provided between the two lifting lug plates 41.

[0009] Furthermore, the side trunnion assembly 3 and the trunnion reinforcing plate 5 are provided in at least two sets and are symmetrically arranged at both ends of the platform body 2.

[0010] Furthermore, an axial flow fan for increasing air circulation is installed inside the platform body 2.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: using this device to repair its water-cooled furnace opening not only eliminates the scaffolding erection process, greatly shortening the repair time, but also reduces the hidden dangers caused by personnel not being able to avoid the operation in time during the hoisting route, ensuring the overall repair efficiency and safety, while reducing the workload of the staff, making it more practical and convenient.

[0021] See Figures 1-7 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a platform body 2, an upper cover plate 1 welded to the upper end of the platform body 2, a lifting lug mechanism 4 provided at one end of the platform body 2, and a trunnion reinforcing plate 5 and a bottom plate connecting plate 6 installed on the side of the platform body 2. A side trunnion assembly 3 is welded to the upper end of the trunnion reinforcing plate 5, and the end of the side trunnion assembly 3 is welded to the platform body 2. A lower bottom plate 8 is welded to the bottom end of the bottom plate connecting plate 6, and a door panel 7 is provided on one side of the platform body 2.

[0022] More specifically, the base plate connecting plate 6 has at least two sets, and is symmetrically arranged on both sides of the platform body 2. The base plate connecting plate 6 is used to connect to its lower base plate 8, and the lower base plate 8 ensures the flatness of the bottom of the platform body 2.

[0023] More specifically, the side trunnion assembly 3 includes a side trunnion post 31. One end of the side trunnion post 31 is welded with a limiting baffle 33, and the other end of the side trunnion post 31 is welded to the platform body 2. A trunnion sleeve 32 is fitted onto the side trunnion post 31. The side trunnion post 31 is used for the suspension of the overhead crane, while the limiting baffle 33 can prevent the suspension rope from loosening. The trunnion sleeve 32 can protect the side trunnion post 31 and extend its service life.

[0024] More specifically, the lifting lug mechanism 4 includes two lifting lug plates 41, one end of which is welded to the platform body 2, and a lifting lug shaft 42 is provided between the two lifting lug plates 41.

[0025] More specifically, at least two sets of side trunnion assemblies 3 and trunnion reinforcing plates 5 are provided and symmetrically arranged at both ends of the platform body 2. The trunnion reinforcing plates 5 can increase the connection stability of their side trunnion assemblies 3, while multiple side trunnion assemblies 3 can facilitate the operation of the overhead crane.

[0026] More specifically, the main body 2 of the platform is equipped with an axial flow fan to increase air circulation.

[0027] The working principle of this utility model is as follows: When the water tank at the furnace opening leaks and needs to be repaired by welding, the staff can use this device. The side of the platform body 2 is provided with a door panel 7, and the top of the platform body 2 is sealed with a cover plate 1. An axial flow fan is installed inside the platform body 2 to circulate the air inside the platform body 2. When the water-cooled furnace opening leaks and needs repair, the staff should first level the furnace. At this time, the repair worker will use a crane to lift this device to the repair position. The repair personnel can enter the interior of the water-cooled furnace through the door panel 7 to weld the leak point. This can effectively shorten the repair time and greatly improve the safety performance. The crane suspends this device through the side trunnion assembly 3 and the lifting lug mechanism 4. When not in use, its bottom plate 8 can ensure that the device is placed stably.

[0028] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
