Description

Technical Field

[0001] The utility model relates to an integral roller table shared by multiple strands, belonging to the technical field of continuous casting machine equipment in the metallurgical industry. Background Art

[0002] The continuous casting machine pours molten steel into the mold through the tundish, and then pulls it out by the straightening machine. After the billet pulled out by the straightening machine is cut by the cutting car, it is transported to under the transverse steel transfer car by the roller table, and the transverse steel transfer car pushes the billet onto the walking beam cooling bed. During the production process of the continuous casting machine, the roller table of the continuous casting machine plays an important role in connecting the upstream and downstream in the production process of the billet. With the development of the continuous casting machine towards multi-strand, the original single-strand small roller table driven by chain drive was adopted, which was driven by a speed reducer through chain drive. The transmission system was very large, and the connection was complex, often malfunctioning. Moreover, the speed reducer, transmission shaft, coupling, and sprocket were all under the roller table, making it difficult to maintain. In addition, it was found during use that the chain-driven small roller table was prone to chain dropping, and the speed reducer sometimes had damaged anchor bolts, resulting in a large amount of maintenance work. Therefore, this single-strand small roller table driven by chain drive restricted the steel-pulling production of the continuous casting machine. Content of the Utility Model

[0003] The purpose of the utility model is to provide an integral roller table shared by multiple strands, which has a simple structure, stable and reliable transmission, and is easy to maintain, so as to solve the problems existing in the background art.

[0004] The technical solution of the utility model is as follows:

[0005] An integral roller table shared by multiple strands includes several rollers arranged in parallel. Each roller is driven by a motor, and several hoops are arranged along the axial direction on each roller, and each hoop corresponds to one strand of the continuous casting machine.

[0006] The cross-section of the hoop is a U-shaped structure matching the billet.

[0007] The roller includes a roller body, a left shaft, a right shaft, a left end cover, and a right end cover. The roller body is a hollow structure. The hoop is fixed on the outer surface of the roller body. A left end cover is provided at the left end of the roller body, and a right end cover is provided at the right end of the roller body. A cavity for cooling water is formed between the left end cover, the roller body, and the right end cover. The left shaft is fixed on the left end cover, the right shaft is fixed on the right end cover, and central holes communicating with the cavity are respectively provided on the left shaft and the right shaft.

[0008] The left shaft and the right shaft in the roller are respectively rotatably connected to the bearing seats through bearings.

Detailed Embodiment

[0015] The following further illustrates the present utility model through examples in conjunction with the drawings.

[0016] Referring to the attached Figure 1-2 , a multi-strand shared integral roller table includes several rollers 18 arranged in parallel. Each roller 18 is driven by a motor 9. Along the axial direction of each roller 18, several hoops 4 are provided, and each hoop 4 corresponds to one strand of the continuous casting machine.

[0017] In this embodiment, referring to the attached Figure 1-2 , the multi-strand shared integral roller table of the present utility model is composed of a left I-beam 10, a right I-beam 11, and several rollers 18. The roller 18 is composed of a left rotary joint 1, a left bearing 2, a billet 3, a hoop 4, a roller body 5, a right bearing seat 6, a reducer 7, a right rotary joint 8, a motor 9, a cavity 12, a left shaft 13, a right shaft 14, a left end cover 15, and a right end cover 16. Left end covers 15 and right end covers 16 are respectively welded to both ends of the roller body 5 of each roller 18. A left shaft 13 and a right shaft 14 are respectively welded to the left end cover 15 and the right end cover 16. The left shaft 13 and the right shaft 14 are fixed to the left I-beam 10 and the right I-beam 11 through the left bearing seat 2 and the right bearing seat 6. A left rotary joint and a right rotary joint 6 are respectively installed at the end parts of the left shaft 13 and the right shaft 14. The left rotary joint 1, the left shaft 13, the cavity 12 inside the roller body 5, the right shaft 14, and the right rotary joint 6 form a cooling water passage to cool the roller body 5 and prevent the roller body 5 from deforming.

[0018] Hoops 4 are installed at the positions where each strand of the roller body 5 passes through the billet. The hoop 4 is a circular ring surrounded by a U-shaped plate. Its inner diameter matches the outer diameter of the roller body 5. The width of the U-shaped plate matches the outer dimension of the billet. The edge of the hoop 4 plays a guiding role.

[0019] A speed reducer 7 is installed on the right shaft 14 on the right side of the roller body 5, and a motor 9 is also installed and connected to the speed reducer 7. The anti-rotation baffle 17 is used to connect and fix the speed reducer 7 and the right I-beam 11 to prevent the speed reducer 7 from rotating.
