[0026] like Figures 1 to 4 As shown, according to an embodiment of the present invention, a rolling detachable skirt side roller assembly is provided, such as... Figure 1 and Figure 2 As shown, the skirt board side roller assembly includes a skirt board frame 1 and a side roller assembly 11. The skirt board frame 1 is used to install and fix the side roller assembly 11. The skirt board frame 1 includes a bottom plate 12, two side plates 13, and a top plate 14. The bottom plate 12, one side plate 13, the top plate 14, the other side plate 13, and the bottom plate 12 are connected in sequence. The top plate 14 is provided with mounting holes 15, and a bearing seat 18 is provided on the inner wall of the mounting hole 15. The side roller assembly 11 is installed in the mounting hole 15 through the bearing seat 18. A guide plate 6 is provided on the top plate 14 located on one side of the mounting hole 15. When the steel travels to the skirt board frame 1, the steel uses the conveying force of the roller conveyor to simultaneously form friction with the roller body 2 and the guide plate 6. The roller body 2 rotates freely and flexibly, reducing the quality problems caused by the steel being marked.

[0027] Furthermore, such as Figure 4As shown, the side roller assembly 11 includes a roller body 2 and two connecting shafts 4. The two connecting shafts 4 are respectively located at both ends of the roller body 2. One end of the connecting shaft 4 is located inside the roller body 2, and two bearings 7 are sleeved on the connecting shaft 4. The bearings 7 are high-temperature resistant bearings. The roller body 2 is rotatably connected to the connecting shaft 4 through the bearings 7. Two bearing seats 18 are provided, and the two bearing seats 18 are respectively located on both sides of the roller body 2. The other ends of the two connecting shafts 4 extend into the two bearing seats 18 respectively. The axis of the connecting shaft 4 is perpendicular to the axis of the skirt frame 1 along its length. The surface of the roller body 2 is higher than the outer surface of the guide plate 6. The connecting shaft 4 cooperates with the bearing seats 18 on the skirt frame 1 to realize the smooth rotation of the roller body 2.

[0029] Furthermore, an oil injection nozzle 8 is provided at the other end of a connecting shaft 4. An oil passage is provided inside the connecting shaft 4 with the oil injection nozzle 8. One end of the oil passage is connected to the oil injection nozzle 8, and the other end of the oil passage is connected to the bearing 7. Oil can be supplied to the bearing 7 by injecting oil into the oil passage through the oil injection nozzle 8, thereby improving the operating stability and service life of the side roller assembly 11.

[0030] Furthermore, the side roller assembly 11 is fixed to the fixed frame by means of snap-fit ​​or bolt connection. In one embodiment of this utility model, the other end of the connecting shaft 4 is snap-fitted to the side plate 13. In another embodiment of this utility model, a fastening screw 9 is also included. The fastening screw 9 passes through the top plate 14 and abuts against the connecting shaft 4. Tightening the fastening screw 9 can fix the connecting shaft 4. The side roller assembly 11 adopts the above-mentioned block structure and is designed to be lightweight (by hollowing out the inside of the roller body 2, only retaining the mounting holes of the bearing 7 to achieve the purpose of weight reduction), and is equipped with a high-temperature resistant bearing 7. The structure is compact and easy to install.

[0031] Furthermore, the top plate 14 is provided with threaded holes 10. After the bolt passes through the guide plate 6, it engages with the threaded holes 10 to connect the guide plate 6 to the top plate 14. The guide plate 6 is subjected to heat treatment to improve its wear resistance and scratch resistance.

[0032] Furthermore, the roller body 2 is made of wear-resistant alloy material, and the surface of the roller body 2 is covered with laser-clad wear-resistant material to improve wear resistance and scratch resistance, increase friction with the steel, and prevent the steel from slipping during the conveying process.

[0033] Furthermore, such as Figure 3As shown, the guide plate 6 includes a first section 16 and a second section 17. One end of the first section 16 and the second section 17 are connected. The first section 16 is located at the end of the top plate 14 away from the side roller assembly 11, and the second section 17 is located in the middle of the top plate 14. The other end of the first section 16 is inclined toward the inside of the skirt frame 1.

[0034] Furthermore, the skirt frame 1 is made of cast steel, with a length of 651.4 mm and a height of 282.7 mm. The guide plate 6 has a thickness of 25 mm. In the vertical section along the width of the skirt frame 1, the top plate 14 is curved with a radius of 625 mm and its center is located below the top plate 14. The bottom plate 12 is also curved with a radius of 350 mm and its center is located below the bottom plate 12. The angle between the two side plates 13 is 35°. The top plate 14 has a width of 383.5 mm, and the bottom plate 12 has a width of 210.5 mm. This configuration enables the skirt frame 1 to have good load-bearing capacity and stability.
