Embodiment Construction

[0028] The content of the present invention will be described in detail below in conjunction with specific embodiments. The specific language or sequence in the specific embodiments is only for explanation and demonstration, and should not have any limiting effect on the protection scope of the present invention.

[0029] The present invention provides a method of leveling an outrigger. The level sensor detects the inclination angle in the direction of the two coordinate axes, judges the horizontal state of the outrigger according to the inclination angle, finds the highest outrigger or the higher side outrigger, and adjusts the lower outrigger or the lower side outrigger, During the adjustment process, continue to detect and judge until all outriggers are in a horizontal state. Since the leveling and detection and judgment are performed simultaneously, and multiple outriggers are adjusted simultaneously during the leveling process, the leveling can be realized more quickly an...

Abstract

The invention discloses a method for carrying out the leveling of support legs and an automatic leveling device which adopts the method. A horizontal sensor detects tilt angles on two coordinate axis directions, the judgment of the horizontal state of the support legs is carried out according to the tilt angles, the highest support leg or the higher side support leg are found, the lower support leg or the lower side support leg is regulated, and the detection and the judgment are continuously carried out during the regulation process till all the support legs are in the horizontal state. As the leveling, the detection and the judgment are simultaneously carried out and a plurality of support legs are simultaneously regulated during the leveling process, the leveling can be realized more rapidly and more accurately. The invention further provides the automatic leveling device based on the method. The automatic leveling device can be connected with an original manual regulating system in parallel, and the two systems are mutually independent. Therefore, the impact of human factors can be overcome through the automatic leveling, the leveling precision is high, the period is short and the repeatability is high.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a method for leveling outriggers and an automatic leveling device using the method. Background technique [0002] The application of construction machinery is becoming more and more extensive, and they are often equipped with hydraulic outriggers. For example, construction vehicles such as concrete pump trucks and truck cranes are equipped with telescopic hydraulic outriggers. Generally, the number of hydraulic outriggers is four, two on each side of the engineering vehicle, and the four hydraulic outriggers should ensure that the chassis of the engineering vehicle remains horizontal. During the construction process, because the position of the center of gravity of the vehicle may be constantly changing, or because the working surface of the engineering vehicle changes, the chassis of the vehicle may tilt. In order to prevent the engineering vehicle from tipping over, it is n...
