The lifting device 3 is arranged at the bottom of the transport ladder, and is used to pull the transport vehicle 2 to move along the transport ladder to transport the materials to the construction platform 1. In order to facilitate the removal of the materials from the transport vehicle 2, the transport vehicle 2 needs to be changed from an inclined state to a horizontal state. Therefore, a first folding portion 4 is arranged at the top of the transport ladder, and when the transport vehicle 2 reaches the first folding portion 4, the first folding portion 4 is folded toward the construction platform 1. A support buffer device 5 is arranged on the top of the first folding portion 4 near the construction platform 1. The support buffer device 5 is supported on the construction platform 1, and when the transport vehicle 2 slowly changes from an inclined state to a horizontal state, it can play a buffering role for the transport vehicle 2. In this embodiment, the support buffer device 5 is specifically a hydraulic rod. The fixed end of the hydraulic rod is rotatably connected to the top of the first folding portion 4.

When the transport ladder needs to be moved, the first folding portion 4 and the second folding portion 6 can be folded to shorten the length of the transport ladder for easy transportation. The overall length of the transport ladder is set according to the height of the construction platform 1 and the tilt angle of placement, and the width is set according to the width of the items to be loaded. In this embodiment, the first folding portion 4, the second folding portion 6 and the straight portion 7 each include two parallel columns 8, and a plurality of parallel beams 9 are fixed between the columns 8, and the beams 9 are arranged perpendicular to the columns 8 at intervals. The transport vehicle body 2 can roll along the columns 8. In order to facilitate the rolling of the transport vehicle body 2, the columns 8 are made of channel steel, and the channel steel is used as the transport track of the transport vehicle body 2. The beam 9 is fixed by welding a steel pipe with the channel steel. In order to place the transport ladder stably, the bottom of the transport ladder needs to be flush with the ground contact point. Therefore, the bottom of the channel steel can be cut according to the angle of the transport ladder so that the bottom of the channel steel is placed on the ground in an inclined manner.

A first guide wheel 17 is fixed to the middle of both sides of the mounting rod 19. The mounting rod 19 can be a steel pipe. A second guide wheel 18 is installed in the middle of one side of the second folding portion 6 close to the construction platform 1. The wire rope 20 of the lifting device 3 passes through the side of the second guide wheel 18 close to the second folding portion 6, passes through the outer sides of the two first guide wheels 17 and is hooked on the transport vehicle body 2. When the first folding portion 4 is folded, the second guide wheel 18 supports the wire rope 20 to prevent the wire rope 20 from touching the edge of the construction platform 1. The second guide wheel 18 is mounted on the crossbeam 9 at one end of the second folding portion 6 close to the first folding portion 4 .

[0043] Preferably, a vehicle stop 21 is provided at the top of the first folding portion 4 and the bottom of the straight portion 7. The specific shape of the vehicle stop 21 is not limited. In this embodiment, a T-shaped vehicle stop 21 is welded on the top of the column 8 of the first folding portion 4 and the bottom of the column 8 of the straight portion 7 on the side where the transport vehicle body 2 is placed, so as to limit the transport vehicle body 2 and prevent the transport vehicle from leaving the transport ladder.

[0044] Specifically, in order to facilitate the installation of the lifting device 3, a fixing rod 22 is further provided on the side of the straight portion 7 close to the lifting device 3, and the lifting device 3 is arranged on the fixing rod 22. A reinforcing rib 23 is provided between the end of the fixing rod 22 and the straight portion 7.

In order to make the lifting device 3 more secure, a reinforcing rib 23 is welded between the fixing rod 22 and the column 8.

[0045] In this embodiment, if Figure 4 As shown, the transport vehicle body 2 is welded by channel steel, and the size is determined according to the material to be transported. A bracket 24 is symmetrically welded at the bottom of the transport vehicle body 2 to fix the roller 25, and the roller 25 is rotatably connected to the bracket 24. The bracket 24 is made of angle steel. A stop bar 26 is welded on the side of the transport vehicle body 2 close to the bottom of the transport ladder to prevent the transported materials from sliding down. A lifting lug 27 is welded in the middle of the side of the transport vehicle body 2 away from the stop bar 26. The steel wire rope 20 pulled out from the lifting device 3 passes around the second guide wheel 18 and the first guide wheel 17 and is hooked on the lifting lug 27, driving the entire transport vehicle body 2 to roll along the transport ladder.
