[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] For examples, please refer to Figs. 1-3 This utility model provides a technical solution:

[0025] A push-pull unloading platform for building construction includes an external fixed unloading platform 1, with pull ring hooks 101 on both the left and right sides of the external fixed unloading platform 1, an internal movable unloading platform 2 inside the external fixed unloading platform 1, and an unloading platform drive mechanism 3 inside the external fixed unloading platform 1 that works in conjunction with the internal movable unloading platform 2.

[0026] In this embodiment, please refer to Fig. 3The unloading platform drive mechanism 3 includes two sets of symmetrically distributed bearing seat brackets 301. A drive shaft 302 is rotatably connected between the two sets of bearing seat brackets 301. A rotating bracket 303 is fixedly sleeved on the middle section of the drive shaft 302. A flip-up base plate 304 is connected to the rear side of the rotating bracket 303. The right end of the drive shaft 302 extends out of the bearing seat bracket 301 and is connected to a gear 305. A fixed crossbar 306 is installed on the right side of the bottom of the external fixed unloading platform 1. A forward and reverse motor 307 is provided at the front end of the fixed crossbar 306. The output end of the forward and reverse motor 307 passes through the interior of the fixed crossbar 306 and is connected to a rotating screw. The outer side of the rotating lead screw 308 is threaded with a lead screw sleeve 309. The top of the lead screw sleeve 309 extends into the interior of the outer fixed unloading platform 1 and is connected to a rack 310 that meshes with the gear 305. The forward and reverse motor 307 is started to drive the rotating lead screw 308 to rotate, thereby driving the lead screw sleeve 309 to move along the direction of the rotating lead screw 308, driving the rack 310 to mesh with the gear 305. The rotation of the gear 305 drives the drive shaft 302 to rotate, causing the rotating bracket 303 and the flipping base plate 304 to move, ultimately driving the inner movable unloading platform 2 to flip upward ninety degrees.

[0027] The outer fixed unloading platform 1 is equipped with a controller on its outer side. The controller is connected to the forward and reverse motors 307 by wires and the connection is electrical. The bearing seat bracket 301 is fixedly installed at the front end of the bottom of the inner side of the outer fixed unloading platform 1 by bolts. The bottom of the inner movable unloading platform 2 is fixedly installed on the top of the flip base plate 304 by bolts. Both ends of the rotating screw 308 are rotatably connected to the inside of the fixed crossbar 306 through bearing seats. The top of the fixed crossbar 306 and the outer fixed unloading platform 1 are provided with rectangular grooves for the movement of the screw sleeve 309.

[0028] The working process of this utility model is as follows: In use, after the external fixed unloading platform 1 is installed and fixed, the material can be unloaded onto the internal movable unloading platform 2. After unloading, the forward and reverse motor 307 is started to drive the rotation of the rotating screw 308, thereby driving the screw sleeve 309 to move along the direction of the rotating screw 308, driving the rack 310 to mesh with the gear 305. The rotation of the gear 305 drives the drive shaft 302 to rotate accordingly, causing the rotating bracket 303 and the flipping base plate 304 to move. Finally, the internal movable unloading platform 2 can be flipped upwards by ninety degrees, thereby transferring the internal material into the building. This solves the problem that the material is heavy and large, making it inconvenient for construction personnel to transfer it from the unloading platform to the building, resulting in reduced construction efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
