Abstract

The invention discloses an automatic leveling method for supporting legs. The supporting legs comprise horizontal supporting legs and vertical supporting legs, an absolute displacement sensor for acquiring the extending length of the vertical supporting legs and a relative displacement sensor for acquiring the vertical height difference of the vertical supporting legs relative to the reference vertical supporting legs are correspondingly arranged on each vertical supporting leg; and the automatic leveling method for the supporting legs comprises the following steps that all horizontal supporting legs are enabled to extend to a position; all vertical supporting legs are enabled to extend to a preset length L1; the vertical supporting leg with the highest vertical height direction is selected as a reference vertical supporting leg according to the relative displacement sensor, and then the rest vertical supporting legs are subjected to telescopic adjustment according to the vertical height difference value of the relative reference vertical supporting legs obtained by the relative displacement sensors at the same time, until the difference between the vertical height obtained by therelative displacement sensors is zero, and leveling is completed; and the vertical height direction is perpendicular to the horizontal plane. The automatic leveling method has the advantages of beingsimple and rapid in leveling operation, high in efficiency, high in precision and the like.

Description

technical field [0001] The invention relates to an automatic leveling method for outriggers, and belongs to the technical field of outrigger leveling. Background technique [0002] Equipment such as cranes, aerial work vehicles, and elevating fire trucks are usually equipped with outriggers to ensure sufficient safety and stability during work, and to improve the safety factor of the entire vehicle against tipping. The outriggers are usually set on both sides of the bottom of the equipment chassis, and the number is usually four. They are divided into vertical outriggers and horizontal outriggers. The horizontal outriggers are mainly used to achieve or change the span of the outriggers to adjust the operating range. The legs are mainly used for leveling and carrying the full load of the equipment. When working, the outriggers are stretched, the vertical oil cylinders of each outrigger lift the whole equipment, the tires are off the ground, the whole equipment is completely ...
