The invention relates to the field of building, and provides an automatic transmission device. The device includes a lifting leg for supporting external objects, a first jacking mechanism for jacking up the lifting leg, a feeding mechanism and a control system, wherein the lifting leg includes a plurality of support frames inserted in one another in sequence in the vertical direction; the feeding mechanism is used for automatically conveying another support frame to the position under the lifting leg; the control system is used for controlling the operations of the first jacking mechanism and the feeding mechanism. According to the invention, the first jacking mechanism jacks up the bottom-layer support frame of the lifting leg, the feeding mechanism conveys another support frame to the position under the lifting leg, and the new support frame is connected with the bottom-layer support frame in an inserted manner, so that the lifting leg is lifted; after the first jacking mechanism jacks up the support frame at the last but one layer of the lifting leg, the bottom-layer support frame is separated from the support frame at the last but one layer, and at the moment, the feeding mechanism is used to carry away the bottom-layer support frame, so that the lifting leg is lowered. During the two processes, manual operations are eliminated, the automation degree is relatively high, and the operations are convenient; moreover, the support frame supplement and dismantling for the lifting leg are all completed on the ground, which facilitates the monitoring and can ensure the safety.
