Description

Technical Field

[0001] The utility model relates to the technical field of ladle cars, in particular to an online fault diagnosis device for a ladle car. Background Art

[0002] Ladle cars are electric flat cars used to transport ladles in steel mills. They are driven by electric motors and controlled by frequency converters. According to daily use experience, due to the poor operating conditions of ladle cars, frequency converters are prone to failure during use, causing the ladle car to stop. Once the ladle car stops, the corresponding converter will stop production, causing losses to the steel mill.

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN210944733U discloses a combined ladle car, including a power box, a traction limit box and a carrying box arranged in sequence from bottom to top, the power box is provided with a walking wheel, the traction limit box is fixedly arranged on the power box, the carrying box is slidably arranged on the traction limit box, a ladle is arranged on the carrying box, a winch and a telescopic limit column are arranged on the traction limit box, a hook is fixedly arranged on the free end of the winch wire rope, and a hook cross bar and a limit groove are arranged on the carrying box, which are respectively matched with the hook and the telescopic limit column. When the hook is hung on the hook cross bar to pull the carrying box, the lower edge of the hook is higher than the upper edge of the winch and the telescopic limit column. When the frequency converter in the power box fails, the carrying box and the ladle on the carrying box can be directly and quickly transferred to another traction limit box, so as to ensure the normal transportation of the ladle and avoid the shutdown of the converter due to the failure of the ladle car;
