The invention relates to the technical field of drilling equipment, in particular to a drilling electric direct-drive winch with an emergency protection function. The problem that when a motor breaks down, a heavy object hoisted at the tail end of a steel wire rope can be rapidly released is solved, the motor comprises a bottom plate, the bottom plate is fixedly connected with a fixing shell, one side of the bottom plate is fixedly connected with a first driving piece through a support, a power output shaft of the first driving piece is fixedly connected with a rotating shaft, and the rotating shaft is rotationally connected to the fixing shell in a penetrating mode. The rotating shaft is fixedly connected with a winding drum, a steel wire rope is wound on the winding drum, a manual brake mechanism is arranged on the other side of the bottom plate, and a first emergency brake mechanism is arranged on the bottom plate. The rotating shaft and the winding drum are braked through friction between the third sliding part and the sliding groove of the second fixing frame, the rotating shaft and the winding drum are kept in a locked state, the hand brake assembly is triggered through the L-shaped sliding frame to brake the rotating shaft, and therefore the braking time of the rotating shaft and the braking time of the winding drum are shortened.

    本发明涉及钻井设备技术领域,尤其涉及一种具有应急防护功能的钻井电动直驱绞车。解决了电机发生故障时,在钢丝绳尾端吊装的重物的影响下会使其急速释放的问题,其包括有底板,底板固接有固定壳,底板的一侧通过支架固接有第一驱动件,第一驱动件的动力输出轴固接有转轴,转轴贯穿转动连接于固定壳,转轴固接有收卷筒,收卷筒绕设有钢丝绳,底板的另一侧设置有手动刹停机构,底板设置有第一应急刹停机构。本发明通过第三滑动件和第二固定架的滑动槽的摩擦,对转轴和收卷筒进行刹停,并且使转轴和收卷筒保持锁死状态,通过L形滑动架触发手刹组件对转轴和进行刹停,进而缩短转轴和收卷筒的刹停时间。
