The second construction unloading platform 2 is hingedly installed on one side of the first construction unloading platform 1. A controller is installed on the back of the first construction unloading platform 1.

[0025] In this embodiment, a supporting structure and a lifting mechanism are provided below the first construction unloading platform 1; the supporting structure includes four guide telescopic parts 6 fixedly mounted on the four corners of the lower surface of the first construction unloading platform 1 and a frame 8 welded between the four guide telescopic parts 6; the guide telescopic part 6 is composed of a telescopic cylinder 601 and a telescopic sleeve 602 connected telescopically, and the top of the telescopic sleeve 602 is fixed to the lower surface of the first construction unloading platform 1 by bolts, and the bottom end of the telescopic cylinder 601 is rotatably mounted with casters 7; the lifting mechanism includes a driving motor 9 fixedly mounted on the upper surface of the frame 8, a bidirectional screw 10 arranged above the frame 8, a transmission structure installed on the output shaft of the driving motor 9 and the end of the bidirectional screw 10, a sliding sleeve 13 threadedly mounted on the outside of the bidirectional screw 10 and two connecting rods 14 welded on the outer wall of the sliding sleeve 13 on the side away from each other, and the two connecting rods 14 are hingedly mounted on the lower surface of the first construction unloading platform 1 at one end with two symmetrically arranged pushing arms 15.

[0026] It should be noted that the interior of the telescopic cylinder 601 is hollow, and the bottom end of the telescopic sleeve 602 extends into the telescopic cylinder 601. A stopper is fixedly mounted on the outer surface of the bottom end of the telescopic sleeve 602 and is slidably connected to the interior of the telescopic cylinder 601. Brake pads are mounted on the exterior of the casters 7. When in use, the installation of the casters 7 facilitates the movement of the unloading platform to the desired position, and the brake pads are mounted on the exterior of the casters 7 to secure the unloading platform.

[0027] A mounting platform is fixedly mounted on the outer wall of the telescopic sleeve 602 near the second construction unloading platform 2, and an adjustment mechanism 5 is hingedly installed between the mounting platform and the second construction unloading platform 2 to adjust the angle of the second construction unloading platform 2. The adjustment mechanism 5 is a second electric telescopic rod, and the angle of the second construction unloading platform 2 is adjusted by its telescopic adjustment.

[0028] In this embodiment, a vertical plate 3 is welded to the upper surface of the first construction unloading platform 1 away from the second construction unloading platform 2. The pushing mechanism 4 includes a first electric telescopic rod and a pushing plate. The pushing plate is installed on the output end of the first electric telescopic rod by bolts. The first electric telescopic rod is fixedly installed on the vertical plate 3, and its output end passes through the interior of the vertical plate 3.

[0029] It should be noted that the interior of the frame 8 is hollow, and a reinforcing cross bar 16 is welded between the inner walls on opposite sides thereof. Coaxial and collinear mounting seats 17 are fixedly mounted on the frame 8 and the reinforcing cross bar 16, and the bidirectional screw 10 is mounted between the three mounting seats 17 through bearings.

A limit rod is fixedly mounted between the inner walls of the frame 8 on the opposite side away from the reinforcing cross bar 16 to limit the two sleeves 13 so that they can move stably. The bidirectional lead screw 10 is driven to rotate by the transmission cooperation of the drive motor 9, the worm 11 and the worm wheel 12. Since the threads on the bidirectional lead screw 10 are arranged in opposite directions, the two sleeves 13 are displaced relative to or apart, thereby driving the push arm 15 to raise and lower the first construction unloading platform 1 and the second construction unloading platform 2, effectively improving the flexibility of the unloading platform, facilitating use by staff, and improving the flexibility of the unloading platform.

[0032] During use, the installation of the caster 7 makes it convenient for the staff to move the unloading platform to the desired position, and the brake pad is installed on the outside of the caster 7 to fix the unloading platform. The bidirectional screw 10 is then driven to rotate by the transmission cooperation of the driving motor 9, the worm 11 and the worm wheel 12. Since the threads on the bidirectional screw 10 are arranged in opposite directions, the two sleeves 13 are displaced relative to or apart, thereby driving the pushing arm 15 to lift and lower the first construction unloading platform 1 and the second construction unloading platform 2, effectively improving the flexibility of the unloading platform and facilitating use by the staff.

[0033] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
