The invention belongs to the technical field of power low-temperature cold start engineering, and discloses a gearbox oil way system, a crane and a gearbox oil way system starting method.The gearbox oil way system comprises a gearbox body, a gearbox oil way, a heating circulation oil way and a detection control unit; the heating circulating oil way comprises a heating oil tank independent of the gearbox body and an electric heater arranged in the heating oil tank, the heating oil tank communicates with the gearbox body through a pipeline, and the detection control unit can detect the temperature of gearbox oil in the gearbox body and control the electric heater and the electric bypass valve. By arranging the heating oil tank independent of the gearbox body, enough space can be provided for installing the electric heater with higher power, the electric heater with higher power can ensure that the gearbox oil can be rapidly heated to the normal starting temperature under the extremely cold condition, and therefore it is ensured that a gearbox oil way system can be normally started under the extremely cold condition.
本发明属于动力低温冷启动工程技术领域并公开了一种变速箱油路系统、起重机及变速箱油路系统启动方法,变速箱油路系统包括变速箱本体、变速箱油路、加热循环油路以及检测控制单元,加热循环油路包括独立于变速箱本体设置的加热油箱以及设置在加热油箱内的电加热器,加热油箱和变速箱本体之间通过管路连通,检测控制单元能够检测变速箱本体内的变速箱油的温度并对电加热器和电旁通阀进行控制。通过设置独立于变速箱本体的加热油箱以能够提供足够的空间来安装更大功率的电加热器,大功率的电加热器能够保证在极寒条件下将变速箱油快速加热到正常启动温度,从而保证变速箱油路系统在极寒条件下也能够正常启动。
