The invention provides a safety device for fully automatically controlling
elevator falling and a manufacturing method. A full-automatic mechanical control device composed of a plurality of componentsis arranged in a closed mechanical control box of the device, a motor, a first gear, a second gear, a penetrating-type rotating screw, a first support
pier, a first nut, a second supporting
pier anda second nut are sequentially arranged in a
machine box from
right to left, a bearing and an elastic
brake box are arranged at the left end of the penetrating-type rotating screw, a first braking vaneis arranged on the left side of the elastic
brake box, a retractable spring is arranged in each of an upper port and a lower port of the elastic
brake box, a second braking vane of the same model anda steel
wire rope pulling
elevator lifting are arranged on the left side of the first braking vane, a first automatic switch, a second automatic switch and a third automatic switch are arranged on the part, between the first supporting
pier and the second supporting pier, of the
machine box, a first manual switch and a second manual switch are further arranged on the right side of the
machine box, and a first steel
wire rope guide-in groove is formed on the left side of the closed mechanical control box. The device is economical, practical and high in safety factor.
