[0040] See also Figure 1 to Figure 5 As shown, the expandable cantilever unloading platform includes:

[0041] Unloading platform 1;

[0042] Two side panels 2 vertically arranged on opposite sides of the unloading platform 1;

[0043] An end plate 3 connected to the two side plates 2 and fixed at one end of the unloading platform 1; a first sliding channel 20 is provided in the unloading platform 1 along the connecting direction of the two side plates 2, two sliding plates 5 are slidably connected inside the first sliding channel 20, and the relative outer sides of the two sliding plates 5 are respectively connected to the two side plates 2; a second sliding channel is provided in the end plate 3 along the connecting direction of the two side plates 2, and two end slide plates 22 are slidably connected in the second sliding channel, and the relative outer sides of the two end slide plates 22 are respectively connected to the two side plates 2; a first driving component for driving the two slide plates 5 to slide relative to each other is installed at the bottom of the unloading platform 1;

[0044] The two side plates 2 and the end plate 3 are both provided with a mezzanine, the mezzanine of the end plate 3 is parallel to the second sliding channel, an extension plate 6 is slidably connected in the mezzanine, the tops of the three extension plates 6 respectively extend out of the corresponding side plates 2 or the end plates 3 and are connected together through synchronous connecting pieces, and any one or more of the two side plates 2 and the end plates 3 are connected with a second driving component for driving the corresponding extension plate 6 to extend upward along the mezzanine;

[0045] By providing the sliding plate 5, the end slide plate 22, the extension plate 6 and the first drive assembly and the second drive assembly, the lateral and longitudinal expansion of the cantilevered unloading platform is achieved, the number of lifting times is reduced, and the construction efficiency is improved.

[0046] Specifically, two steel pipes are connected to one end of the unloading platform 1 which is relatively far away from the end plate 3. The two steel pipes extend out of the outer edge of the end of the unloading platform 1 and form two cantilevered sections. By setting the cantilevered sections, the hoisting of the overall structure is facilitated, and the unloading turnover is facilitated.

[0053] Specifically, anti-slip flanges are formed at both ends of the slide rod 24, and an anti-slip convex edge is provided at the open end of the connecting sleeve 23 for preventing the anti-slip flange from slipping out. By providing the anti-slip flange and the anti-slip convex edge, the slide rod 24 is not easily detached from the connecting sleeve 23, thereby enhancing the stability of the connection.

[0054] Preferably, the second driving component is an electric cylinder 7 , which is vertically fixed to the inner side of the side plate 2 or the end plate 3 , and a protruding plate 13 for connecting the piston rod of the electric cylinder 7 is fixed to the top of the corresponding extension plate 6 .

[0055] Preferably, batteries 11 for supplying energy to the electric cylinder 7 are fixed inside the two sliding plates 5 , and a conductive member is connected between the electric cylinder 7 and the batteries 11 .

[0056] Preferably, the conductive member includes a first conductive sheet 9 fixed on the unloading platform 1, and a second conductive sheet 10 fixed on the sliding plate 5, the first conductive sheet 9 is electrically connected to the electric cylinder 7, the second conductive sheet 10 is electrically connected to the battery 11, and the second conductive sheet 10 contacts the first conductive sheet 9 when it moves outward to a certain distance relative to the sliding plate 5.

[0057] Specifically, the conductive member includes a first conductive sheet 9 fixed on the unloading platform 1 and facing a position on the forward thread segment away from one end of the reverse thread segment or on the reverse thread segment away from one end of the forward thread segment, and a second conductive sheet 10 fixed on the sliding plate 5 and facing a position on the forward thread segment close to one end of the reverse thread segment or on the reverse thread segment close to one end of the forward thread segment.

[0058] Preferably, solar panels 12 for charging the corresponding batteries 11 are installed on the outer sides of the two side panels 2. The solar panels 12 are electrically connected to the batteries 11 through spring wires. By providing the solar panels 12, the subsequent installation and removal steps of the batteries 11 are avoided, the work efficiency is improved, and the green construction requirements are met.

[0063] The sliding of the two side plates 2 drives the two end slide plates 22 connected thereto to slide outwards relative to each other;

[0065] When one or more extension plates 6 slide upward, all the extension plates 6 are caused to slide upward synchronously through the synchronous connecting member until they are vertically expanded to a certain height.

[0068] When the first driving component drives the two sliding plates 5 to slide outward relative to each other, the second conductive sheet 10 on the sliding plate 5 moves in the direction of the first conductive sheet 9. When the sliding plate 5 slides horizontally to the limit distance, the first conductive sheet 9 fits with the second conductive sheet 10 to supply power to the electric cylinder 7 to automatically expand vertically.
