A method for calibrating a vehicle weighing system

Abstract

The invention relates to a method for calibrating a driving weighing system, comprising: returning to zero, weighing at an initial position, weighing at a verification position, and weight compensation. The method for calibrating the weighing system of the traveling crane provided by the present invention utilizes the characteristic that the weight change of the steel wire rope used in the hook of the traveling crane has a linear relationship with the height to realize the automatic calibration of the weighing system of the traveling crane. The calibration method is simple and fast, It has high efficiency and does not affect production. It can detect the abnormality of the weighing system in time, and adjust it by human intervention in time to ensure the accuracy of the weighing system.

Description

technical field

[0001] The invention relates to a method for calibrating a vehicle weighing system, which belongs to the technical field of iron and steel manufacturing. Background technique

[0002] There are multiple cranes installed in the workshop of the foundry and steelmaking plant, and these cranes are equipped with load cells on the fixed pulley block of the main coil to complete the weighing of the weight of the main coil, which is used to calculate the amount of iron added in a single furnace and the amount of steel tapped in a single furnace ( The weight of the full ladle before ironing minus the weight of the empty ladle after ironing is the amount of iron added in a single furnace; the amount of full ladle after tapping minus the weight of the empty ladle before tapping is the amount of steel in a single furnace) Model steelmaking provides important parameter basis.

[0003] The accuracy of the weighing system is very important for model steelmaking, and the ra...
