The invention discloses an automatic gear shifting winch. The winch comprises a winch body driving an external drilling machine, a pneumatic control system installed on the winch body and used for driving the winch body to shift gears, a driller operating system controlling the winch body to ascend and descend and connected with the pneumatic control system through a gas circuit, a sensor installed on the external drilling machine and used for recording the load of the drilling machine, a brake mechanism controlling the winch body to brake, and a control system electrically connected with thesensor and used for controlling the brake mechanism, the pneumatic control system and the driller operating system to work, wherein the pneumatic control system is connected with the driller operatingsystem through a pipeline. According to the winch, the lifting load is measured by the sensor, when the winch is in a braking state and the drilling machine does not start to be lifted, data is fed back to a PLC control system, the system processes the data and sends out a gear engaging signal, gear engaging can be achieved when a main gas circuit is connected, gear engaging delay cannot be caused, and timeliness is guaranteed.

    本发明公开了一种自动换档绞车,包括带动外部钻机的绞车主体,安装于所述绞车主体上且用于驱动所述绞车主体换档的气控系统,控制绞车主体提升和下降且与气控系统气路连接的司钻操作系统,安装于外部钻机上且用于记录钻机荷载的传感器,控制所述绞车主体刹车的刹车机构,以及与所述传感器电性连接且用于控制刹车机构、气控系统和司钻操作系统工作的控制系统,其中,所述气控系统与司钻操作系统管路连接。本发明的提升载荷由传感器测量,当处于刹车状态且未开始提升钻机时,数据已经反馈到PLC控制系统,由系统处理并发出挂档信号,待主气路接通,即可挂档,不会造成挂档延迟,时效性有保证。
