[0002] A converter is an important steelmaking equipment in the iron and steel industry, mainly used to refine molten iron and scrap steel into molten steel through an oxidation reaction. Converter steelmaking is one of the main methods of modern steel production, and it is widely popular due to its high efficiency, environmental friendliness, and relatively low cost. Because there is a certain distance between the furnace platform and the tapping spout, a tapping spout platform is usually set up between the furnace platform and the tapping spout to facilitate personnel to change the tapping spout.

[0003] According to the search, a steel outlet platform with publication number CN213866292U can effectively prevent slag from falling from the flue through its top plate, thereby effectively protecting the personal safety of workers.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Example 1:

[0033] Please see Figure 1-6 A steel tapping platform, comprising:

[0034] The base 1 has four columns 2 fixedly connected to its top. Multiple guard rods 3 are assembled between two columns 2 on the same side. The top of the two columns 2 on the same end is provided with a detachable bearing seat 4. The inner side of the bearing seat 4 is provided with a positioning component 5.

[0035] The top plate 6 has two fixedly connected insertion rods 7 on both ends of its inner side, and the insertion rods 7 are inserted into the inside of the bearing seat 4. Each insertion rod 7 has a locking hole 8 at its bottom end, and the positioning component 5 is used to lock the top plate 6 in conjunction with the locking hole 8.

[0036] In this embodiment, the column 2 is provided with multiple assembly holes 18, and the guard rod 3 is connected between two corresponding assembly holes 18 by bolts. The assembly holes 18 provide assembly space for the bolts, and the guard rod 3 can be easily assembled with the help of the bolts. When the guard rod 3 is damaged, the guard rod 3 can be disassembled by separating the bolts from the guard rod 3.

[0037] In this embodiment, each column 2 has a mounting plate bolted to its top, and the bearing seat 4 is bolted to the top of the column 2.

[0038] In this embodiment, multiple reinforcing plates 19 are fixedly connected between the two bearing seats 4. Each reinforcing plate 19 is fixedly connected to a buffer pad at one end near the top plate 6. By setting the reinforcing plates 19, the middle part of the top plate 6 can be auxiliaryly supported after the top plate 6 is assembled, ensuring the application effect of the top plate 6. In addition, with the setting of the buffer pad, the impact on the top plate 6 can be mitigated to a certain extent, preventing the top plate 6 from deforming.

[0039] In this embodiment, both ends of the top of the support 4 are provided with inclined surfaces, and the top plate 6 is adapted to the inclined surfaces. Through the structural cooperation between the support 4 and the top plate 6, the material blocked by the top plate 6 can slide down with the slope of the surface of the top plate 6, thus preventing the material from staying on the top plate 6.

[0040] In this embodiment, each support 4 has a socket at its top. The socket allows the insertion rod 7 to pass through the socket and reach the inside of the support 4 for assembly.

[0041] Example 2:

[0042] Please see Figure 1-6 This embodiment provides a technical solution based on Embodiment 1: the positioning component 5 includes:

[0043] Two support seats 9 are fixedly connected to the two ends inside the bearing seat 4, and a drive shaft 10 is rotatably connected between the two support seats 9. A guide plate 11 is fixedly connected to the outside of the drive shaft 10. A locking block 12 is fixedly connected to the end of the guide plate 11 away from the drive shaft 10, and the locking block 12 is engaged with the locking hole 8.

[0044] An eccentric plate 13 is fixedly connected to the middle of the transmission shaft 10. A push rod 14 is rotatably connected to the end of the eccentric plate 13 away from the transmission shaft 10. A displacement plate 15 is vertically slidably connected to the bottom end of the bearing seat 4. The end of the push rod 14 away from the eccentric plate 13 is also rotatably connected to the top end of the displacement plate 15.

[0045] The transmission screw 16 is rotatably connected to the middle of the displacement plate 15. The middle of the bearing seat 4 is fixedly connected to the threaded sleeve 17, and the transmission screw 16 is also threadedly connected to the middle of the threaded sleeve 17.

[0046] In this embodiment, both the locking hole 8 and the locking block 12 are arc-shaped structures. By utilizing the shape characteristics of the locking block 12, the locking block 12 can be stably locked into the locking hole 8 by means of the revolution of the locking block 12 along the transmission shaft 10, thereby effectively locking the insertion rod 7 in conjunction with the locking hole 8.

[0047] In this embodiment, a guide seat is fixedly connected to the side of the bearing seat 4 away from the push rod 14. A guide rod is vertically slidably connected to the middle of the guide seat, and the bottom end of the guide rod is fixedly connected to the displacement plate 15. By setting the guide rod, the displacement of the displacement plate 15 can be vertically guided, avoiding uncontrollable rotation of the displacement plate 15, and greatly ensuring the stability of the displacement plate 15 in application.

[0048] In this embodiment, a mounting ear is fixedly connected to one end of the top of the displacement plate 15, and the end of the push rod 14 away from the eccentric plate 13 is connected to the mounting ear through a rotating shaft. By setting the mounting ear, the push rod 14 can be stably assembled with the help of the rotating shaft, ensuring the linkage effect between the push rod 14 and the eccentric plate 13 and the displacement plate 15.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0050] Working principle: The base 1 is installed at the position where the steel tapping outlet needs to be replaced, so as to shorten the distance between the furnace front platform and the steel tapping outlet through the base 1. Then, the personnel enter the base 1 to replace the steel tapping outlet. During the operation, the top plate 6 can be used to support the slag adhering to the flue, making the operation of the personnel safer.

[0051] Furthermore, after the top plate 6 is damaged, the transmission screw 16 can be rotated. With the transmission screw 16 connected to the threaded sleeve 17, the transmission screw 16 can be vertically displaced at the threaded sleeve 17, thereby changing the position of the displacement plate 15. Since the push rod 14 is connected between the displacement plate 15 and the eccentric plate 13, when the displacement plate 15 is displaced, the push rod 14 can pull the eccentric plate 13. Since the eccentric plate 13 is supported by the transmission shaft 10, the transmission shaft 10 and the guide plate 11 can drive the locking block 12 to rotate until the locking block 12 is moved out of the locking hole 8, thereby unlocking the insertion rod 7. Then the top plate 6 can be lifted up to separate the top plate 6 from the bearing seat 4, and then the top plate 6 can be replaced.
