The invention belongs to the technical field of heavy engineering mechanical equipment, and particularly relates to a single-winch refitted double-winch system based on an automobile hydraulic crane.The system comprises a winch bracket, a forehead pulley bracket and a main controller, and is characterized in that the flow direction of hydraulic oil is changed by closing an electronic switch, electrifying and exciting an electromagnetic valve and opening a control oil path by taking the main controller as a center; and an auxiliary winch hydraulic motor is driven to drive an auxiliary winch towork, a steel wire rope is connected with a small hook head to rise and fall quickly, a travel switch and a three-circle protector measure and control data, and if the limit is exceeded, overload occurs and the winch rope remaining amount is not enough, electronic signals are transmitted to the main controller which opens a forced unloading valve through current to stop rising and falling actions, so that safe construction and person protection are achieved. Through integration of various functions, combination of software and hardware and conversion of hydraulic energy and mechanical energy,gear lifting and upgrading of an existing single-winch automobile crane are achieved, the working efficiency is improved by more than 6 times, and original six-hour work is saved to one-hour work.

    本发明属于重型工程机械装备技术领域,尤其是涉及基于汽车液压起重机的单卷扬改装双卷扬系统,包括卷扬机支架、额头滑轮支架和主控制器,内部以主控制器为中心,通过闭合电子开关,电磁阀通电励磁,打开控制油路改变液压油流向,驱动副卷扬液压马达,带动副卷扬机工作,钢丝绳连接小钩头快速起落,行程开关与三圈保护器测控数据,如果超限、超载和卷扬留绳量不够,通过电子信号传输给主控制器,主控制器通过电流打开强制泄荷阀,停止起落动作,从而安全施工保护人物,通过各种功能的集成、软件与硬件的结合、液压能与机械能的转换,实现了现有单卷扬汽车起重机的提档升级,使得工作效率提高6倍以上,原本六小时的工作节省至一小时完成。
