Problems solved by technology

Obviously, the single-leg leveling method cannot meet the above requirements, but a multi-point leveling method must be used, which brings new challenges to the design of the leveling system
[0003] Among the known multi-point leveling methods, such as the method and system for leveling the outriggers of engineering vehicles disclosed in the application number 94104847.0, the outriggers in the same row are all connected in parallel by adjusting the X direction first and then the Y direction. There are some deficiencies in the actual application of oil supply: 1. When the inclination angle of the car body is large, the system cannot guarantee the synchronization of the lowering of a row of outrigger

Abstract

The invention provides a four-point leveling method of a platform. The method comprises the following steps that: legs extend out to touch a ground, rough regulation is performed in a large dip angle range, the legs stretch to a predetermined height, and fine regulation is carried out in a small dip angle range. The invention also provides a four-point leveling system of a platform, and the system comprises locking sleeve hydraulic legs (7)-(10), legs in-position inductors (19)-(22), a display and control combiner (30), a leveling controller (31), a hydraulic valve set (32), a pressure detection group (33) and a horizontal angle sensor (34). The system is simple in structure and control logic, the risk of side overturning in a control process is avoided, and the frequency of leveling is reduced.

Description

technical field [0001] The invention belongs to the technical field of electromechanical control, and in particular relates to a four-point leveling method for the center of a platform and a leveling system thereof. Background technique [0002] The automatic leveling technology using hydraulically driven outriggers is widely used in various special vehicles. For special vehicles working on the prefabricated field level, most of them use the single-leg leveling method due to the small range of leveling angles. For some special vehicles with high mobility requirements, it is necessary to level the vehicle on a site with a slope of 2.5° or 3°, while meeting the requirements of high leveling accuracy, short leveling time, and long time for maintaining accuracy. Obviously, the single-leg leveling method cannot meet the above requirements, and a multi-point leveling method must be used, which brings new challenges to the design of the leveling system. [0003] Among the known m...
