The invention relates to the technical field of petroleum drilling operation equipment, in particular to a remote control system for a man-carrying and object-carrying pneumatic winch. The system comprises an air inlet main stop valve, one end of the air inlet main stop valve is connected with an air inlet pipeline, the other end of the air inlet main stop valve is connected with an air flow control shutoff valve through a pipeline, and the air flow control shutoff valve is respectively connected with a main air inlet valve and a winch starting valve through pipelines. The winch starting valve is connected with a safety control pressure cavity through a pipeline, and the safety control pressure cavity is connected with a main air inlet valve. According to the invention, the man-carrying mode and the object-carrying mode can be mutually switched, during man carrying, when gas is cut off, a heavy object is hooked with other objects, and the heavy object runs to the highest position or the lowest position, automatic braking and hovering can be realized, the functions of emergency parking, overload protection parking and upper and lower limit control protection parking are realized, and the personal safety of lifting and descending operators is ensured.
本发明涉及石油钻井作业设备技术领域,特别涉及一种载人载物气动绞车远程控制系统。该系统包括进气总截止阀,进气总截止阀一端与进气管线相连接,进气总截止阀另一端通过管线与气流量控制截流阀相连接,气流量控制截流阀通过管线分别与总进气阀和绞车启动阀相连接,绞车启动阀通过管线与安全控制压力腔体相连接,安全控制压力腔体与总进气阀相连接。本发明实现了载人载物模式能够互相转换,载人时,在遇到断气、重物和其它物体勾连、重物运行到最高位或最低位时能够自动刹车并悬停,实现应急停车、过载保护停车和上下限位控制保护停车功能,确保起升下降作业人员人身安全。
