A floating oil way (4) is connected between a first internal working oil way (1) and a second internal working oil way (2), and the two end points of the floating oil way (4) are located between an A2 connecting port and a hydraulic lock (3) on the first internal working oil way (1) and between a B2 connecting port and a hydraulic lock (3) on the second internal working oil way (2) respectively. The floating oil way (4) is provided with an on-off oil supplementing valve unit for controlling the on-off of the floating oil way (4), and the on-off oil supplementing unit is connected with an internal oil supplementing oil way (5), so that the floating oil way (4) is communicated with the internal oil supplementing oil way (5) when the floating oil way (4) is in an on state. In addition, the invention further provides a leveling device, the pile driver and a control method of the leveling device of the pile driver. On the basis of the prior art, the function of enabling the hydraulic execution element to float is added, and therefore damage to the guide pile frame during pile pulling of the pile driver is eliminated.
平衡阀，其中第一内部工作油路(1)和第二内部工作油路(2)之间连接有浮动油路(4)，该浮动油路(4)的两端点分别在所述A2连接端口与该第一内部工作油路(1)上的液压锁(3)之间、所述B2连接端口与该第二内部工作油路(2)上的液压锁(3)之间，该浮动油路(4)上设置有用于控制该浮动油路(4)通断的通断补油阀单元，该通断补油单元连接有内部补油油路(5)，以在浮动油路(4)导通状态下，使得所述浮动油路(4)与所述内部补油油路(5)连通。此外，本发明还提供一种调平装置、打桩机和打桩机调平装置控制方法。本发明在现有技术的基础上增加了使液压执行元件浮动的功能，从而消除了打桩机在拔桩时对导向桩架的破坏。
