Problems solved by technology

When working in other directions, due to the improvement of the stability of the vehicle, the allowable operating range is increased. At this time, the single-range control method will inevitably lead to a too conservative control range of the vehicle, which cannot fully utilize the operating capacity of the vehicle.

Abstract

The invention discloses a variable amplitude operating range obtaining and controlling method, device and system. The method comprises the steps that a rotation plane operation curve decided by whole vehicle stability is obtained; a variable amplitude plane amplitude curve decided by the cantilever crane material strength is obtained; when an engineering mechanical vehicle cantilever crane is in any posture, the rotation plane operation curve is inquired according to the rotation angle of the posture, the first maximum amplitude corresponding to the rotation angle is determined, the variable amplitude plane amplitude curve is inquired according to the variable amplitude angle of the posture, and the second maximum amplitude corresponding to the rotation angle is determined; and the minimum value of the first maximum amplitude and the second maximum amplitude serves as the maximum allowed amplitude of the posture, and accordingly, the whole vehicle safety operation range is determined. The variable which is the rotation angle is introduced into the obtained rotation plane safety operation range, and therefore the maximum operation amplitude is distinguished and limited according to different degrees of whole vehicle stability, the operation capability of a whole vehicle is fully utilized, and the maximum operation amplitude of the whole vehicle is remarkably improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a method, device and system for acquiring and controlling a range of luffing operations. Background technique [0002] High-altitude operation vehicle is a kind of special vehicle with the functions of high-altitude rescue, high-altitude transportation of materials and high-altitude engineering operations. It is widely used in engineering construction and emergency rescue. The booms of aerial work vehicles are mostly in the form of telescopic booms, and can rotate around the center of rotation. The booms at different positions correspond to different maximum allowable elongations, which is the safe operating range of the vehicle. Among them, the maximum operating range of the vehicle at different slewing angles is mainly determined by the overturning stability of the vehicle, while the maximum operating range of the boom at different luffing angles is mainly determined by the...
