Embodiment 1

[0039] Using the above scheme, a closed-loop control system is composed of two level sensors, leveling valve group, leveling outriggers, outrigger pressure transmitters, and hydraulic consoles. The hydraulic control console collects the two base level angle values ​​and the pressure value of the leveling legs of the special vehicle in real time through the CAN bus communication board and the A / D board respectively. The pressure value of the corresponding proportional valve group is sent through the D / A board to adjust the spool switch value of the corresponding leveling proportional valve group in real time, thereby driving the corresponding leveling leg action to achieve fast, high precision and high reliability for special vehicles Leveling purpose.

[0040] The leveling steps are as follows:

[0041] 1) After the hydraulic console receives the "leveling" command, the special vehicle enters the automatic leveling procedure and starts leveling;

[0042] 2) For special vehic...

Abstract

The invention provides a double-base-plane biaxial levelling control system. The double-base-plane biaxial leveling control system comprises a console, leveling valve sets, leveling supporting legs and a launching vehicle, wherein the console is connected with and controls the leveling valve sets, hydraulic pipelines of the leveling valve sets are connected with the leveling supporting legs, and the leveling supporting legs are mounted at four corners of the launching vehicle; pressure transmitters are mounted on the leveling supporting legs and are in communication connection with the console; a main sensor and an auxiliary sensor are installed on the launching vehicle and are in communication connection with the console; the main sensor and the auxiliary sensor are respectively arrangedat a position close to the tail and a position close to the head of the launching vehicle; and the console is used for levelling a posture of the launching vehicle by controlling the leveling valve sets to adjust the leveling supporting legs according to reading values of the main sensor and the auxiliary sensor in sequence. The two base planes of a special vehicle can be biaxially and rapidly leveled, the leveling precision is high, and the leveling process is stable and reliable.

Description

technical field [0001] The invention relates to a dual base surface biaxial leveling control system. Background technique [0002] With the advancement of science and technology and society, hydraulic leveling technology is widely used in modern defense and civil technology, such as the application of heavy cranes and other equipment. [0003] To achieve fast, high-precision and reliable leveling for some special-equipped vehicles with dual-base and biaxial leveling with special requirements, it is difficult to achieve fast, high-precision and high-speed leveling through the traditional "chasing" leveling method. Reliable leveling requirements. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a dual-base and bi-axial leveling control system, which can effectively meet the needs of fast, high-precision and high-speed leveling in the leveling process of special equipment vehicles. Reliable requirements. [0...
