Problems solved by technology

When a wheel failure occurs, the horizontal looper car loses its balance instantaneously, or even deviates from the original running direction, and because the looper car runs at a high speed during normal operation, it is easy to hit other objects such as the swing door of the looper after a failure. Equipment, thus expanding the scope of the accident, resulting in longer maintenance time and higher maintenance costs, seriously reducing the production efficiency of the unit

Abstract

The invention discloses a horizontal looping car which comprises a car body, a support fixedly arranged at the lower part of the car body, and four wheel sets pivoted with the support and bracing the car body, wherein each of the four wheel sets comprises at least two wheels; at least 2mm height difference exists between the center of each wheel in at least two wheels and the centers of the other wheels; and a height difference between the center of the lowest wheel and the center of the highest wheel in the four wheel sets does not exceed 10mm. The service life of the horizontal looping car is prolonged significantly; the production efficiency of a cold rolling unit is improved significantly; the maintenance cost is lowered; and the maintenance time is shortened.

Description

technical field [0001] The invention relates to the field of metallurgical machinery cold rolling, more specifically, the invention relates to a horizontal looper. Background technique [0002] The horizontal looper is generally used in the cold rolling process, mainly for storing or releasing the strip steel, so as to ensure the continuous and stable processing operation of the cold rolling unit. Whether the horizontal looper can work normally is an important factor for the unit to process normally. [0003] Once the horizontal looper fails, it will cause the entire production unit to stop. For example, in a horizontal looper, sudden wheel failures are often caused by excessive bearing wear due to poor lubrication conditions of the wheels. When a wheel failure occurs, the horizontal looper car loses its balance instantaneously, or even deviates from the original running direction, and because the looper car runs at a high speed during normal operation, it is easy to hit o...
