The invention discloses a self-adaptive speed regulation driving force and braking force closed-loop regulation dual-function hydraulic system. The system comprises a power output unit of a main system, a power output unit of an auxiliary system, a hydraulic pipeline of a main executing mechanism, a valve group, an auxiliary executing mechanism, a main system and auxiliary system communication control stop valve, a local loop pressure adjusting valve II, an oil return filter, an oil return stop valve and a plurality of sensors which are connected with one another, wherein the power output unit of the main system and the power output unit of the auxiliary system are communicated through the main system and the auxiliary system to control the stop valve. The invention provides the bifunctional hydraulic system which can enable automatic rope changing equipment to be automatically matched with the running speed of an elevator, is wide in self-adaptive speed regulation range, can meet the technical requirement of synchronization, is constant in output driving torque and braking torque, and can be switched between a driving state and a braking state at any time. A new mode selection is provided for the control of the equipment.

    本发明公开了包括相互连接的主系统的功率输出单元、辅系统的功率输出单元和主执行机构的液压管路以及阀组、辅助执行机构、主辅系统连通控制截止阀、局部回路压力调整阀Ⅱ、回油滤油器、回油截止阀和若干传感器,主系统的功率输出单元和辅系统的功率输出单元之间通过主辅系统连通控制截止阀。本发明提供一种可以使自动化换绳设备能够自动匹配提升机的运行速度,自适应调速范围广,可以达到同步的技术要求,且输出驱动力矩、制动力矩恒定,驱动状态和制动状态可以随时切换的双功能液压系统,为该类设备的控制提供一种新方式选择。
