Description

Technical Field

[0001] The utility model relates to the technical field of block making machines, and more particularly to a converter tapping hole annular brick block making machine. Background Art

[0002] In the metallurgical industry, the steelmaking process is the key to ensuring the quality of steel. The outer shell of the steelmaking furnace is made of steel structure parts and lined with high-temperature resistant materials (commonly known as refractory materials). The outlet of the steelmaking furnace is often designed as a round mouth due to the requirements of slag blocking and facilitating the flow of molten steel, and is lined with formed annular refractory bricks.

[0003] The masonry workers are faced with huge physical and technical challenges when laying the taphole ring refractory bricks. Each taphole ring refractory brick weighing 300 kg needs to be accurately installed in the designated position (reference Figure 6 and Figure 7 During this process, workers must rely on specialized tools like manual hoists, crowbars, and levers to lift, align, and secure the refractory bricks. The heavy workload, tight deadlines, and the limited width and height of the work area not only increase the complexity and risk of the operation, but also place extremely high demands on the workers' physical strength and endurance.

[0004] In such a cramped working environment, the installation of each refractory brick requires meticulous work, often lasting five to six hours at a time. The long, intense labor, coupled with the harsh on-site environmental conditions—high temperatures, dust, noise, and confined space—undoubtedly places a significant strain on the workers' health. Furthermore, due to the unique nature and complexity of the work, each masonry operation presents certain safety risks, highlighting the importance of improving existing working methods and introducing automated or semi-automated equipment to reduce labor intensity, improve work efficiency, and ensure operational safety.

[0024] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0025] Combine Figure 1-Figure 5 The converter tapping hole annular brick block making machine of the present invention is mainly used to pull the five annular refractory bricks 7 of the tapping hole 6 to the masonry position, realizing the mechanized transmission and positioning of the annular refractory bricks 7, saving manpower, ensuring safe production and efficient production, and reducing the masonry time. The tapping hole 6 is placed in the masonry position and a limit block is set to prevent the annular refractory bricks 7 from falling from the tapping hole 6. The block making machine includes a bracket 1, a power component and a traction component, wherein the power component is installed on one side of the bracket 1, and the power component drives the traction component to work, driving the annular refractory bricks 7 to move to the masonry position. The bracket 1 is connected to the tapping hole 6 by bolts to support the power component and the traction component. Their structure and working principle are described in detail below.

[0026] In this embodiment, the bracket 1 includes a first steel plate 11, a first steel pipe 12 and a second steel plate 13. The first steel plate 11 and the second steel plate 13 are arranged in parallel. The two ends of the first steel pipe 12 are fixedly connected to the first steel plate 11 and the second steel plate 13 respectively. Bolt holes are provided at both ends of the first steel plate 11, and a flange is provided at the port of the steel outlet 6. The bracket 1 is connected to the steel outlet 6 by bolts passing through the threaded holes on the first steel plate 11 and the flange. The first steel pipe 12 is used to guide the screw 4, and the second steel plate 13 is used for installing and fixing the worm gear reducer 3.

[0027] In this embodiment, the power assembly includes a motor 2 and a worm gear reducer 3. The input shaft of the worm gear reducer 3 is connected to the motor 2, and the output end of the worm gear reducer 3 is connected to the screw 4. The motor 2 adopts a servo motor and can perform stepless speed regulation. The worm gear reducer 3 works under the drive of the motor 2, driving the screw 4 to move horizontally.

[0028] In this embodiment, the traction assembly includes a screw rod 4 and a positioning cover 5. The screw rod 4 passes through the steel outlet 6, and one end of the screw rod 4 engages with the positioning cover 5. When the screw rod 4 moves horizontally, the annular refractory brick 7 is pulled to the masonry position through the positioning cover 5.

[0029] In this embodiment, the screw rod 4 passes through the worm gear reducer 3, and a first dust cover 41 is sleeved on the screw rod 4 between the positioning cover 5 and the worm gear reducer 3, and a second dust cover 42 is sleeved on the screw rod 4 on the other side of the worm gear reducer 3.
