Background Art

[0002] At present, continuous casting workshops of steel enterprises widely use roller conveyors to transport steel billets, and roller conveyors are mostly used for cantilever reducers. In the continuous casting production process, steel billets are formed by the straightening machine and then enter the roller conveyor, which is then transported to the cooling warehouse or heating furnace by the roller conveyor. This part of the roller conveyor area spans the factory beam and dust removal pipeline. During the inspection and regular maintenance period, the roller conveyor under the factory beam or dust removal pipeline is located in the blind area of ​​the driving, so it is inconvenient to replace the motor and reducer. The time and quantity used are almost twice that of the motors and reducers in other driving operation ranges. For example, it takes 6 people to replace the motor in the blind area, but only 3 people are needed to replace the motor in the driving range, and the time is also half as short. Therefore, how to improve work efficiency and reduce workload has become a topic faced by relevant technical personnel. Utility Model Content
