The invention discloses a drive control system applied to a hydraulic capstan. The drive control system comprises a hydraulic motor; the device is characterized in that a balance control functional element, a one-way valve and a plug-in shuttle valve are arranged on the hydraulic motor; the hydraulic motor comprises an oil port A and an oil port B which are used for inputting and outputting oil, the oil of the oil port A and the oil of the oil port B respectively flow into the plug-in shuttle valve and the hydraulic motor, and the oil output by the plug-in shuttle valve is input into the hydraulic capstan brake through a brake unlocking control port U; oil output by the other path of the oil port B flows into the hydraulic motor through the balance control functional element, and the balance control functional element is connected with the one-way valve in parallel. The shuttle valve, the balance valve, the one-way valve and other control elements required by a hydraulic capstan system are integrated into the hydraulic motor body, so that faults such as stall and the like of the hydraulic capstan during load drop can be effectively prevented, and the use safety of the hydraulic capstan is enhanced.
本发明公开了一种应用于液压绞盘的驱动控制系统,包括液压马达;其特征在于,所述包括液压马达上设有平衡控制功能元件、单向阀以及插装式梭阀;液压马达包括用于输入输出油液的油口A、油口B,油口A、油口B的油液分别流入插装式梭阀和液压马达的内部,插装式梭阀的输出的油液通过制动解锁控制口U输入液压绞盘制动器;油口B另一路输出的油液通过平衡控制功能元件流入液压马达的内部,平衡控制功能元件通过并联的方式连接单向阀。本发明将液压绞盘系统所需的梭阀、平衡阀、单向阀等控制元件集成于液压马达本体,可更有效地防止液压绞盘在负载下降时出现失速等故障,增强液压绞盘使用的安全性。
