The invention discloses a hydraulic oil cooling device of a hydraulic drive walking machine. The device comprises a cooling fan, the cooling fan is arranged on an input shaft of a walking oil pump, an air ring is arranged on the outer side of the cooling fan, an oil temperature radiator is arranged on the outer side of the air ring, and the walking oil pump is connected to an engine through an oil pump transmission belt for power transmission. A hydraulic oil tank is arranged on one side of the walking oil pump. The structure is simple, the cost is low, the heat dissipation effect is direct, the heat dissipation fan rotates when the walking oil pump works, and the higher the rotating speed is, the better the heat dissipation effect is. The problem of high temperature of hydraulic oil caused by failure and stalling of the electronic fan is avoided. 本发明公开液压驱动行走机械液压油降温装置，包括散热风扇，所述散热风扇设于行走油泵的输入轴上，所述散热风扇的外侧设有风圈，所述风圈的外侧设有油温散热器，所述行走油泵通过油泵传动皮带连接于发动机进行动力传输，所述行走油泵的一侧设有液压油箱。本发明结构简单，成本低，散热效果直接，行走油泵工作，散热风扇就转动，并且转速越快，散热效果越
