The invention discloses a pipeline winding and unwinding hydraulic control system and a child-mother type drainage vehicle, the pipeline winding and unwinding hydraulic control system comprises an oil tank, an oil pumping device and a pipeline hydraulic driving device, and the oil pumping device is used for pumping out hydraulic oil in the oil tank; the pipeline hydraulic driving device comprises a reversing valve, a pressure control valve and a reel motor in driving connection with a reel wound with a hydraulic pipeline, and the reversing valve is connected with the oil pumping device, the oil tank, an unwinding working oil port of the reel motor and a winding working oil port of the reel motor and used for being switched between an unwinding driving state and a winding driving state. The pressure control valve is arranged on the working oil way where the winding working oil port is connected with the reversing valve, so that after the child car stops, the hydraulic pipeline does not have enough force to enable the pressure of the winding working oil port of the reel motor to be larger than the set pressure of the pressure control valve, and then it is guaranteed that the reel stops reliably. And the phenomena of disordered winding and fluffy winding in subsequent winding are avoided.
本发明公开一种管线收放卷液压控制系统及子母式排水车，管线收放卷液压控制系统包括油箱、泵油装置和管线液压驱动装置，泵油装置用于将油箱内的液压油泵出，管线液压驱动装置包括换向阀、压力控制阀以及与卷设有液压管线的卷盘驱动连接的卷盘马达，换向阀分别与泵油装置、油箱以及卷盘马达的放卷工作油口和收卷工作油口进行连接，并用于在放卷驱动状态与收卷驱动状态之间进行切换，压力控制阀设于收卷工作油口与换向阀连接的工作油路上，则在子车停止后，液压管线没有足够的力来使卷盘马达的收卷工作油口的压力大于压力控制阀的设定压力，进而保证卷盘进行可靠停止，避免后续收卷不会出现乱卷和蓬松缠绕的现象。
