The invention belongs to the field of engineering construction, and particularly relates to a safe carrying winch which comprises a rack, a roller main shaft mounting hole is rotationally formed in the rack, a roller main shaft is detachably and fixedly arranged in the main shaft mounting hole, a speed reduction sliding groove is formed in the circumferential surface of the roller main shaft, and a speed reduction sliding block is arranged in the speed reduction sliding groove in a sealed sliding mode. The roller spindle is provided with a fluid channel penetrating through the center of the roller spindle in the axis direction, the fluid channel penetrates through the bottom of the speed reduction sliding groove and communicates with the speed reduction sliding groove, an oil inlet is formed in the position, away from the spindle mounting hole, of the fluid channel, and an oil discharging channel is formed in the position, close to the spindle mounting hole, in the roller spindle and communicates with the fluid channel. The diameter of the oil discharging channel is smaller than that of the fluid channel, a first bearing is arranged at the end, close to the main shaft mounting hole, of the roller main shaft, a second gear is fixedly connected to the outer ring of the first bearing, and a driving component and an oil pumping component are arranged on the rack. And in case of sudden power failure, the heavy object can be decelerated and safely stopped in the descending process.

    本发明属于工程施工领域,尤其涉及一种安全运载的卷扬机,包括机架,机架上转动设有滚筒主轴安装孔,主轴安装孔内可拆卸固定设有滚筒主轴,滚筒主轴圆周面上开设有减速滑槽,减速滑槽内密封滑动设有减速滑块,滚筒主轴设有沿轴线方向贯穿滚筒主轴中心的的流体通道,流体通道穿过减速滑槽的底部并与减速滑槽连通,流体通道远离主轴安装孔的位置处设有进油口,滚筒主轴内部靠近主轴安装孔的位置处设有卸油道,卸油道与流体通道连通,卸油道直径小于流体通道的直径,滚筒主轴靠近主轴安装孔的一端设有第一轴承,第一轴承的外圈固定连接有第二齿轮,机架上设有驱动部件,机架上设有泵油部件。在突发断电情况,可以使重物在下降过程中减速并安全停下。
