| description | The invention discloses a device for controlling a crane operation speed. The device comprises a first acquisition unit, a first control unit, a second control unit and an energy accumulator, wherein the second control unit is used for acquiring the rotating speed information and operating speed information of a hydraulic pump; whether the rotating speed of the hydraulic pump is matched with the operating speed is judged; if so, an engine maintains the start rotating speed; if not, the rotating speed of the engine and the speed ratio information of a transmission system are acquired; whether the rotating speed of the engine is matched with the operating speed under the current speed ratio is judged; if so, the engine is adjusted to an objective rotating speed status; if not, the speed ratio matching with the operating speed and the rotating speed of the engine are calculated, and the transmission system and the engine are adjusted to the objective speed ratio and the objective rotating speed status. The speed ratio of the intermediate transmission system is changed by the device to adjust the operating speed, and the engine always operates in an economical rotating speed region to reduce the operation fuel consumption of the entire machine. The invention further discloses a method for controlling the crane operation speed. |
