The invention discloses a device and an intelligent control method of a special hydraulic variable-rigidity suspension for a special vehicle, according to the mechanism, when the vehicle runs normally, the whole suspension system is in a flexible state, the vehicle runs normally and smoothly, meanwhile, the vehicle can realize mode switching and intelligent variable-rigidity adjustment according to the vehicle speed, the turning angle and the like, and when the vehicle works, the intelligent variable-rigidity adjustment can be realized. Rigid locking of a whole suspension system is achieved through an electro-hydraulic control loop, construction operation quality and stability are ensured, and the mechanism is composed of a hydraulic oil tank, an oil pump, a floating hydraulic cylinder, a control valve set, a pressure monitor, a corner monitor, an ECU, a frame height monitor, a vehicle speed monitor, an oil return filter and related accessories. The control valve set comprises a first electromagnetic valve, a one-way unloading valve, a second electromagnetic valve, a third electromagnetic valve and a one-way valve, switching among flexibility, rigidity and adjustable rigidity is achieved through on-off control and variable damping of the electromagnetic valves, and the requirements of a vehicle under different working conditions are met.
