Hydraulic control system for ironing plate of paver
The invention discloses a hydraulic control system for an ironing plate of a paver. The hydraulic control system comprises an electric control overflow valve, a three-position four-way electromagnetic directional valve, a two-position two-way electromagnetic directional valve I, a two-position two-way electromagnetic directional valve II, a flow distributing and collecting valve, a first hydraulic oil cylinder, a second hydraulic oil cylinder, a two-position two-way electromagnetic directional valve III and a two-position three-way electric proportional pressure reducing valve; an inlet P1 and an outlet T1 of the electric control overflow valve are connected with a main oil way P and an oil return way T respectively, and an opening of the main oil way P is connected with a pressure measuring opening MP. A pressure port P2 and an oil return port T2 of the three-position four-way electromagnetic valve are respectively connected with the inlet P1 and the outlet T1 of the electric control overflow valve; an outlet A2 and an outlet B2 of the three-position four-way electromagnetic valve are connected with a port P c of the second two-position two-way electromagnetic valve and a port Pa of the first two-position two-way electromagnetic valve respectively. According to the system, the load capacity can be steplessly adjusted during loading and unloading, and the negative influence on the paving quality caused by the unadjustable load capacity in the past is avoided.
本发明公开了一种摊铺机熨平板的液压控制系统，它包括电控溢流阀、三位四通电磁换向阀、二位二通电磁换向阀一、二位二通电磁换向阀二、分流集流阀、第一液压油缸、第二液压油缸、二位二通电磁换向阀三和二位三通电比例减压阀；所述电控溢流阀的进口P1、出口T1分别和主油路P、回油路T相连接，主油路P口和测压口MP相连接；所述三位四通电磁阀的压力口P2、回油口T2分别和电控溢流阀的进口P1、出口T1相连接；三位四通电磁阀的出口A2、B2分别和二位二通电磁阀二的P c口、二位二通电磁阀一的Pa口相连接。本发明在加载、减载时可无级调节载荷量，避免以往载荷量不可调节引起的摊铺质量负面影响。
