s3, controlling a motor (9) to operate, driving a concave sliding plate III (10) on the outer wall of a screw rod lifting assembly II (12) to move forwards and backwards, controlling a screw rod lifting assembly I (8) connected with the concave sliding plate III (10) to move, realizing the displacement of a material box limited by a connecting nail (14) to the outside of a frame of a building frame assembly (1), controlling the screw rod lifting assembly I (8) to operate, driving a cavity threaded pipe arranged in the screw rod lifting assembly I (8) and sliding at the back of a concave sliding plate II (7), realizing the left and right displacement of the connecting nail (14), and when the connecting nail (14) moves materials out of the frame of the building frame assembly (1), controlling an oil cylinder arranged at the top end of the concave sliding plate I (6) to operate, driving the concave sliding plate I (6) and an external frame (5) connected to the front of the concave sliding plate I (6) to move upwards and downwards, and controlling a connected driving shaft column (16) to perform controllable rotation operation through an electric body (4), so that the materials can be placed fully when being placed;
s4: the four corners of the table top of the conveying plate (18) are butted with locking ropes (32) wound on the outer walls of the four groups of bobbins (31), and under normal conditions: the rotary table (38) rotates, after the movable block (43) is contacted with the stirring piece (41), a spring (39) connected with the bottom end of the stirring piece (41) is shortened, the movable block (43) can swing conveniently, after the movable block (43) swings leftwards, a clamping ball (42) connected with one end of the movable block (43) is separated from an outer wall notch of the rotary table (38), so that the clamped ball (42) cannot be clamped in the rotary table (38) in a normal operation state, a group of anti-falling boxes (36) are arranged above the conveying plate (18), falling of the conveying plate (18) is avoided, when the conveying plate (18) is used for carrying boxes, the boxes are prevented from being excessively high in weight, the problems of chain breakage and the like are solved, and the anti-falling boxes (36) are needed to be used for anti-falling, and the anti-falling is particularly as above;
s5: under abnormal conditions, the rotating speed of the rotary table (38) is increased, the contact frequency of the toggle piece (41) and the shaft collar (47) is too high, the frequency of the movable block (43) pulling the clamping ball (42) is also higher, the clamping ball (42) cannot be clamped on the notch of the rotary table (38) under the frequency, the clamping ball can contact the periphery of the notch of the rotary table (38), and the clamping ball (42) is positioned on the periphery of the notch under the stress of the toggle piece (41), so that the limiting to the rotary table (38) is caused.
