Hydraulic pressure automatic leveling method and leveling system for ladle car

Abstract

The invention discloses a hydraulic automatic leveling method for a ladle car. Firstly, it is divided into an X direction and a Y direction according to the plane of the car body, and two inclination sensors corresponding thereto are arranged. Four sets of suspension cylinders and corresponding position sensors; the control unit collects the horizontal position signal of the vehicle body and the position signal of the suspension cylinder in real time through the inclination sensor and position sensor cycle, and judges the highest support point of the vehicle body at a certain moment by the inclination value , and from the size of the inclination and the actual physical distance of the four suspension cylinders in the X and Y directions, calculate the distance difference between the other three points and the highest point; take the highest point as the reference point and keep it still, by controlling the suspension cylinder Up and down, adjust the other three points to move closer to the highest point according to the method of only rising and not falling, until the body reaches the level. The invention can automatically adjust the attitude of the body of the ladle car according to the actual situation in the driving process, so as to avoid the occurrence of inclination or deviation of the center of gravity.

Description

technical field [0001] The invention mainly relates to the technical field of engineering machinery control, in particular to a hydraulic automatic leveling method for a molten iron chartered car. Background technique [0002] In the prior art, the molten iron charter car for metallurgy is a special-purpose transport vehicle, which is mainly used for the transportation of high-temperature liquid molten iron in the iron and steel smelting production process. During use, when the ladle car is driving on an uneven road or turning, the molten iron in the cans on the ladle car will tilt and the center of gravity will deviate. This situation is very unfavorable, and may cause major accidents in severe cases. And so far, the conventional solution is to install a simple control suspension oil cylinder on the ladle car to realize the rise and fall of the vehicle body, but there is no real-time adjustment according to the actual situation of the road surface to keep the level of the ...
