Embodiment Construction

[0076] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0077] The invention provides a modeling method for the chassis leveling program of an aerial work platform. Based on a four-point support hydraulic leveling system, the angle error leveling method is used to perform corresponding leveling operations on the chassis, and the aerial work platform Chassis for support.

[0078] see figure 1 with figure 2 , the chassis of the aerial work platform is composed of a chassis and four legs supporting the chassis. figure 2 Among them, XYZ is the ideal horizontal coordinate system of the chassis, and X 0 Y 0 Z 0 is the chassis initial state coordinate system, α is the angle between the X axis and the X0 axis, indicating the inclination angle of the ...

Abstract

The invention discloses a modeling method for an autonomous leveling system for an aerial work platform chassis. The method comprises the following steps: taking a four-point support type hydraulic leveling system as a basis; adopting an angle error leveling method to carry out corresponding leveling operation on the chassis; adopting an electromagnetic proportional reversing valve for adjusting the flow of a main oil supply way of the hydraulic leveling system, controlling the extending and retracting speed of supporting legs, adopting a switch valve for adjusting the extending and retractingtime of each supporting leg, controlling the precision of the inclination angle of the X axis and the Y axis of the chassis, and finishing leveling work; and finally, compiling a hydraulic leveling system and a chassis leveling process by means of engineering simulation software GX works2. According to the invention, the modeling method of the chassis leveling program is greatly simplified, the design modeling work of hardware and software parts is greatly simplified, and the functions of pressure alarm, angle alarm and the like are added, so that the leveling process is safer and more reliable.
