The invention provides a crane operation heat management control method and a crane, the crane comprises a liquid pump, a plurality of motors and a plurality of throttle valves, the motors are respectively communicated with the liquid pump, the throttle valves are arranged between the motors and the liquid pump, and the crane operation heat management control method comprises the following steps: obtaining motor load rates and motor temperatures of the motors; the cooling liquid flow required by each motor is determined according to the motor load rate and the motor temperature, when the motor temperature is smaller than a preset temperature threshold value, the cooling liquid flow is determined to be a preset cooling liquid flow, and when the motor temperature is larger than the preset temperature threshold value, the cooling liquid flow is determined according to the motor load rate and the motor temperature; and the opening size of each throttling valve is determined according to the flow of the cooling liquid. The method has the beneficial effect that the temperatures and the working states of the multiple motors in the crane can be adjusted more reasonably.

    本发明提出了一种起重机作业热管理控制方法及起重机,起重机包括液泵、多个电机和多个节流阀,电机分别与液泵连通,电机与液泵之间均设置有节流阀,起重机作业热管理控制方法包括步骤:获取电机的电机负载率和电机温度;根据电机负载率和电机温度确定各电机所需的冷却液流量,其中,当电机温度小于预设温度阈值时,确定冷却液流量为预设冷却液流量,当电机温度大于预设温度阈值时,根据电机负载率和电机温度确定冷却液流量;根据冷却液流量确定各节流阀的开口大小。本发明的有益效果:能够更加合理地对起重机中多个电机的温度和工作状态进行调节。
