The two protruding frames 41 are fixed on the outer surface of the transport frame 2. Inside one of the protruding frames 41, a lead screw 42 is rotatably installed. Inside the other protruding frame 41, a limiting rod 43 is rotatably installed. On the top of the fixing plate 44, a servo motor 45 is fixedly installed. One end of the output shaft of the servo motor 45 is fixedly connected to the lead screw 42 through the speed reducer 46. The placement rack 47 is fixed on the top of the transport frame 2. Inside the placement rack 47, a sliding groove 48 is provided. Inside the sliding groove 48, an empty groove 481 is provided. Inside the sliding groove 48, a retractable rack 410 is slidably installed. On both sides of the outer surface of the retractable rack 410, moving blocks 49 are fixedly installed. The right moving block 49 is movably connected to the limiting rod 43. The left moving block 49 is threadedly connected to the lead screw 42. Inside the retractable rack 410, a cable 411 is wound. One end of the cable 411 is fixedly installed with a hook 412; The auxiliary structure 5 includes two fixing blocks 51. Inside the two fixing blocks 51, a door panel 52 is hingedly installed. On one side of the door panel 52, multiple groups of support rollers 53 are provided. A sliding belt 54 is sleeved on the outer surfaces of the multiple groups of support rollers 53. On the other side of the door panel 52, two groups of hinge blocks 55 are hingedly installed. Inside the two groups of hinge blocks 55, a first leg 56 is hingedly installed. Inside the two first legs 56, a second leg 57 is slidably installed. One end of the two groups of second legs 57 is fixedly installed with an anti-slip pad 58.

[0030] Please refer to Figure 1-3 , The buffer structure 3 includes two groups of sliding rails 31 and two limiting plates 38. The two groups of sliding rails 31 are fixed at the bottom of the inner cavity of the transport frame 2. Inside the two groups of sliding rails 31, a bearing platform 32 is slidably installed. On the top of the bearing platform 32, a baffle 33 is fixedly installed. On one side of the baffle 33, four sleeve rods 34 are fixedly installed. The four sleeve rods 34 are movably connected to the transport frame 2 and the transport vehicle frame 1. On one side of the four sleeve rods 34, a resisting plate 36 is fixedly installed. On both sides of the resisting plate 36, sliding blocks 37 are fixedly installed. The two limiting plates 38 are fixed on both sides of the transport vehicle frame 1. The two limiting plates 38 are slidably connected to the sliding blocks 37. On one side of the baffle 33, four springs 35 are fixedly installed. The four springs 35 are sleeved on the outer surfaces of the sleeve rods 34. One end of the four springs 35 is fixedly connected to the inner wall of the transport frame 2.

[0031] When the vehicle brakes, the bearing platform 32 slides inside the sliding rails 31 due to inertia. At this time, through the compression of the four springs 35, the sleeve rods 34 can drive the sliding blocks 37 to slide in the limiting plates 38, thereby buffering the impact generated by the vehicle braking and protecting the steel structures on the top of the transport frame 2 and the bearing platform 32 from damage.

[0032] Please refer to Figure 2 and Figure 8 On one side of the outer surface of the baffle 33, two placement grooves 6 are provided, and the two placement grooves 6 are symmetrically arranged. A plurality of partition rods 7 are placed inside the two placement grooves 6, and the number of the plurality of partition rods 7 can be flexibly adjusted according to the number of steel structures.

[0033] By placing a plurality of partition rods 7 inside the placement grooves 6, each two groups of steel structures are separated by a group of partition rods 7, and finally fixed by steel wires, thereby avoiding damage caused by mutual friction and collision between the steel structures when the vehicle bumps.

[0034] Working principle: When an assembled steel structure construction carrier is in use, first fold the door panel 52 to a negative angle, and then fold the two first legs 56 on both sides to be perpendicular to the ground and pull out and fix the second leg 57 from the inside thereof, thereby supporting the door panel 52. Subsequently, manually carry the steel structure above the sliding belt 54, and hang the steel structure by the hook 412 under the cable 411. Then, driven by the servo motor 45, its output shaft drives the lead screw 42 to rotate through the speed reducer 46. Due to the limitation of the limit rod 43, the two moving blocks 49 can drive the retractable frame 410 to move horizontally inside the chute 48, thereby driving the hook 412 to drive the steel structure to slowly enter the carrier frame 2. At the same time, the operators inside the carrier frame 2 assist in supporting the steel structure above the bearing platform 32 for fixation. When fixing the steel structure, a plurality of partition rods 7 are placed inside the placement grooves 6, and each two groups of steel structures are separated by a group of partition rods 7, and finally fixed by steel wires, thereby avoiding damage caused by mutual friction and collision between the steel structures when the vehicle bumps. Finally, when the vehicle is running, the steel structures are stacked and fixed on the top of the bearing platform 32. When the vehicle brakes, the bearing platform 32 slides inside the sliding rail 31 due to inertia. At this time, through the compression of the four springs 35, the sleeve rod 34 can drive the slider 37 to slide in the limiting plate 38, thereby buffering the impact generated by the vehicle braking and protecting the steel structures on the carrier frame 2 and the top of the bearing platform 32 from damage.
