The fixed plate 6-2 is also provided with a control box 10 for receiving remote control signals and controlling the rotation of the micro-winch 7.

The method of use of the present invention is described below.

(1) According to the drawing 1, a balcony hoisting device is built, and two ends of a telescopic rod piece 1 are supported and fixed on a wall body through anti-skid supports 1-3. At this time, the balcony window is in an open state, and the lifting rod 4 is laterally extended in the outdoor direction. The miniature winch 7 is controlled by remote control, the steel wire rope 7-1 is lowered downwards, and then the heavy object 11 is hung on the electric control hook manually.

The remote control micro-hoist 7 rotates forward, the steel wire 7-1 is lifted, and the heavy object 11 is lifted, as shown in figure 1. At this time, the pulling force T1 of the wire 7-1 = the gravity G of the weight, and the direction of the resultant force F1 is below the hinge shaft 4-2 of the lifting rod 4, that is, the torque of the resultant force F1 to the lifting rod 4 is counterclockwise, so that the lifting rod 4 is not turned over (the counterclockwise direction is limited by the second baffle plate 3-2, and the return spring 5 is in a relaxed state).

When the weight 11 rises below the cross-bar section 4-4 of the lifting bar 4, the fixed pulley 8 is blocked and the weight 11 does not rise any more, see fig. 2. At this time, after the pulling force of the wire 7-1 is increased to T2, the direction of the resultant force F2 of the gravity G of the weight 11 and the pulling force T2 of the wire 7-1 is turned above the hinge shaft 4-2 of the hoist link 4, i.e., the torque of the resultant force F2 to the hoist link 4 becomes clockwise, the hoist link 4 starts to turn indoors, and the weight 11 is transferred indoors, see fig. 3.

When the inclined plane 4-3 at the lower end of the hoisting rod 4 is abutted against the first baffle 2-2, the turning towards the indoor direction is stopped, and the forward rotation of the remote control micro-winch 7 is stopped. At this time, the return spring 5 is in a stretched state, see fig. 4 (the lifting rod 4 is maintained in this state by the traction of the weight 11 and the wire 7-1 at the upper end of the lifting rod 4).

The remote control micro-winch 7 rotates reversely, the steel wire rope 7-1 hung with the heavy object 11 is lowered downwards, and after the heavy object 11 reaches the balcony floor, the remote control micro-winch 7 stops rotating reversely, which is shown in fig. 5.

The electrically controlled hook is remotely controlled to lower the weight 11, see fig. 6.

After the heavy object 11 is unloaded, the hoisting rod 4 is tilted towards the outdoor direction under the action of the return spring 5 and extends out of the window again to prepare for hoisting the next heavy object, see fig. 7.

The operation is repeated, and then a plurality of heavy objects can be lifted and unloaded by a single person in a remote control manner.

(2) And (5) folding and storing. Referring to fig. 8, after the balcony lifting device is used, the bolts at the two ends of the diagonal member bar 3 are pulled out, the bolt at the hinged position of the upper end of the support bar 6-1 is pulled out, the lifting rod bar 4 is folded clockwise, the support bar 6-1 is folded anticlockwise, and the winch fixing rod 6 is folded clockwise. The vertical rod member 2 is folded clockwise, and the telescopic rod member 1 is retracted. The first connecting rod 2-1 can be disassembled, so that the occupied space is smaller.
