[0020] A method for using a lifting device for construction, the method comprising the following steps:

[0021] Step 1: First, when the user needs to transport and lift the building materials, the user can first turn on the motor 2, the output shaft of the motor 2 drives the pulley 1 to rotate, the pulley 1 drives the belt to move, and the belt then transmits the transmission force to the pulley 2, so that the pulley 2 starts to move, and finally the threaded rod is driven to rotate by the pulley 2, and the threaded rod drives the transmission frame to rotate through the engagement of the thread teeth, but at the same time, under the cooperation of the vertical rod, the limit groove and the limit block, the movement state of the transmission frame is limited, so that the transmission frame can only move up and down on the surface of the vertical rod, and finally the transmission frame drives the fixed box to move in the same direction, and realizes the lifting of the transmission frame, and completes the adjustment of the up and down displacement distance of the transmission frame; then the user turns on the motor 1 again, and the output shaft of the motor 1 drives the threaded rod, the vertical rod and the slider to rotate in the inner cavity of the slide groove 2 through the connection of the connecting plate, and further the threaded rod and the vertical rod drive the fixed box to realize the position adjustment in the circumferential direction, so as to be more conducive to the fixed box to transport goods to users in different directions;

[0022] Step 2: When the user realizes the transportation and lifting of the building materials through the fixed box and needs to take the building materials in the fixed box, the user can first push the two locking rods toward the inner cavity of the connecting frame. After the locking rods are retracted to the inner cavity of the connecting frame under the action of the spring, the baffle is opened and the electric telescopic rod is turned on. The output end of the electric telescopic rod pushes the transmission rod 1 to move downward. At the same time, since the transmission rod 1 is connected to the fixed plate, the transmission rod 1 will rotate with the connecting axis between the transmission rod 1 and the fixed plate as the center of the circle under the push of the electric telescopic rod. Further, the transmission rod 1 drives the adjustment frame to move in the same direction. The adjustment frame then transmits the force to the transmission rod 2, and at the same time pulls the transmission rod 2 to flip outward with the connecting axis between the transmission rod 1 and the fixed plate as the axis. Finally, the adjustment frame is moved to the outside of the adjustment frame under the transmission of the electric telescopic rod, the transmission rod 1 and the transmission rod 2, and then the adjustment frame drives the building materials inside it to move out of the inner cavity of the adjustment frame at the same time, thereby replacing the user bending over to pick up the building materials inside the adjustment frame, and the building materials can be taken more quickly.

[0023] Beneficial effects. The technical solution of the present application has the following technical effects: the present invention has the advantages of a more stable lifting process and more convenient use. In actual use, the lifting and transportation of construction materials is realized by driving the fixed box to rise and fall with a threaded rod. It can not only suppress the shaking generated during the transportation of construction materials and realize more stable transmission, but also further improve the diversity of lifting and transportation of construction materials by adjusting the different placement positions of the fixed box. Finally, by actively pushing out the construction materials in the fixed box, it not only speeds up the picking of construction materials and saves operation time, but also replaces the inconvenience of users bending over to operate, thereby reducing the user's operating load.
