The invention discloses an electro-hydraulic servo integrated winch, and relates to the technical field of winch hydraulic systems, in particular to an electro-hydraulic servo integrated winch. The device comprises a pump station module and a roller module, the pump station module and the roller module are connected through an oil supply pipeline; a servo motor and a two-way hydraulic pump of the pump station module are fixedly installed on the two sides of the integrated valve block respectively, and the servo motor is connected with the two-way hydraulic pump. The oil tank is installed on the integrated valve block and located on one side of the two-way hydraulic pump, and the two-way hydraulic pump is sealed in the oil tank. The output end of a hydraulic motor of the roller module is connected with a roller to drive the roller to rotate; the sequence valve is arranged on the main oil way and located in front of an oil inlet of the hydraulic motor, and when the electro-hydraulic servo system drives the winch to unwind a rope, the sequence valve can enable the main oil way to generate certain back pressure, and the winch is prevented from being overspeed. According to the technical scheme, the problems that in the prior art, the size is large, installation is not changed, the requirement for the cleanliness of hydraulic oil is high, and a servo valve is prone to damage and expensive are solved.
本发明电液伺服集成卷扬机,涉及卷扬机液压系统技术领域,尤其涉及电液伺服集成的卷扬机。本发明包括:泵站模块和滚筒模块;泵站模块和滚筒模块通过供油管路相连接;泵站模块的伺服电机和双向液压泵分别固定安装在集成阀块的两侧,伺服电机和双向液压泵相连接;油箱安装于集成阀块上,位于双向液压泵的一侧,并将双向液压泵封闭于其中;滚筒模块的液压马达的输出端与滚筒相连接,带动滚筒转动;顺序阀布置于主油路上,位于液压马达进油口前,当电液伺服系统驱动卷扬机放绳时,顺序阀可以使主油路产生一定背压,防止卷扬机超速。本发明的技术方案解决了现有技术中的体积大、安装不变,对液压油清洁度要求高、伺服阀容易损坏且昂贵的问题。
