Abstract

The embodiment of the invention discloses a chassis leveling system. The system comprises an electric control part and a hydraulic part, wherein the electric control part is used for controlling the hydraulic part; the hydraulic part is used for leveling a chassis; the electric control part comprises an inclined angle sensor which is installed under a revolving shaft of the chassis and used for detecting whether pins are leveled or not and a programmable logic controller (PLC) used for controlling the hydraulic part; and the hydraulic part comprises a power source, an overflow valve, electromagnetic valves which are respectively installed on the four pins, hydraulic cylinders which are respectively installed on the four pins and hydraulic relays which are respectively installed on the four pins. The invention also discloses a chassis leveling method. The chassis leveling system and method control the hydraulic part to automatically level the chassis by the sensor and the PLC, can rapidly and accurately adjust the heights of the pins and solve the problems of low precision and low speed in the manual leveling process.

Description

technical field

[0001] The invention relates to the field of construction machinery, in particular to a chassis leveling system and method. Background technique

[0002] Among the many construction machines, there are many construction machines with vehicle chassis hydraulic outriggers that need chassis leveling under working conditions. For example: various hydraulic cranes, various hydraulic fire engines, ladder vehicles, etc. In the military field, various anti-aircraft artillery vehicles also need to level the chassis of the artillery.

[0003] There are two requirements for vehicle leveling: one is the leveling accuracy; the other is the speed of the leveling action. The high precision of leveling can improve the working efficiency and safety of engineering vehicles, and can improve the hit rate of artillery firing; the high speed of leveling action is very necessary for various emergency engineering vehicles, especially military vehicles. Therefore, the high precisio...
