Abstract

The invention discloses an electro-mechanical and hydraulic integrated design-based hydraulic leveling control system, which comprises a central processing unit, a level sensor connected with the input end of the central processing unit, a human-machine interface unit, a hydraulic system connected with the output end of the central processing unit, four leveling supporting legs and four auxiliary supporting legs. The hydraulic system mainly comprises an alternating current servomotor, a hydraulic pump, a hydraulic manifold block and hydraulic motors which are connected in turn. Each leveling supporting leg is connected with the hydraulic manifold block through one hydraulic motor. According to the invention, the control and power drive requirements of the hydraulic leveling system are realized by adopting the PLC-controlled electro-mechanical and hydraulic integrated technology, the hydraulic motors are controlled to drive through intelligent real-time detection of the level inclination angle of a level inclination sensor component, the four supporting legs are linked and adjusted to the level status. The electro-mechanical and hydraulic integrated design-based hydraulic leveling control system has the advantages of being high in integration degree of the hydraulic system, stable and reliable in operation, low in failure rate, simple and convenient to maintain, compact in size and high in hydraulic leveling accuracy.

Description

technical field [0001] The invention relates to a hydraulic automatic leveling system, in particular to a hydraulic leveling control system based on electromechanical-hydraulic integration design for large and medium-sized radar vehicle vehicle platforms, communication vehicles and various engineering vehicles. Background technique [0002] Vehicle-mounted platforms, communication vehicles and various engineering vehicles often need to work in a completely horizontal state. Generally, four support legs are installed on vehicle-mounted platforms, communication vehicles and various engineering vehicles, and the support points of the four support legs are connected to form a rectangle. After the platform or vehicle is fixed at a certain position, the platform is realized by adjusting each support leg. Or the leveling adjustment of the vehicle. The Chinese invention patent with the application number 201010588391.5 provides a leveling method based on four-point support and an e...
