[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4An embodiment of this utility model provides a commercial vehicle transport semi-trailer, including a cab 1 and a body 2. The body 2 is located at the rear end of the cab 1. A rear wheel 4 is provided at the rear of the lower end of the body 2. A lifting structure 3 is provided at the front of the upper end of the rear wheel 4. A first vehicle 5, a second vehicle 6, and a third vehicle 7 are arranged in a front-to-back arrangement at the upper end of the body 2.

[0028] The lifting structure 3 includes a groove 301, which is formed on the upper surface of the vehicle body 2. Two through holes 302 are formed on the rear sides of the lower inner wall of the groove 301. A second hydraulic cylinder 303 is rotatably connected inside each of the two through holes 302. The output ends of the two second hydraulic cylinders 303 are rotatably connected to first connecting seats 304. An aircraft jump 305 is fixedly connected to the other end of each of the two first connecting seats 304. The front end of the aircraft jump 305 is rotatably connected to the front part of the groove 301. When the second vehicle 6 to be transported is driven to the upper end of the lifting structure 3, the two second hydraulic cylinders 303 are controlled to extend. The two second hydraulic cylinders 303 push the two first connecting seats 304 upwards, causing the aircraft jump 305 to rotate along the rotational position relative to the groove 301, thus flipping the rear end of the second vehicle 6 upwards. Then, the third vehicle 7 to be transported is driven to the rear part of the groove 301, near the rear of the upper end of the vehicle body 2.

[0029] The rear end of the vehicle body 2 is fixedly connected to the rear end of the vehicle tail 8. The rear end of the vehicle tail 8 is provided with a support structure 9, which facilitates the first vehicle to be transported 5, the second vehicle to be transported 6 and the third vehicle to be transported 7 to be driven onto the vehicle body 2.

[0030] The upper surface of the aircraft jump 305 is provided with a limiting strip 306 and a limiting seat 307 arranged in a front-to-back manner at the center rearward position to prevent the second vehicle to be transported 6 from moving on the aircraft jump 305. The second vehicle to be transported 6 is set on the upper surface of the aircraft jump 305, so that the aircraft jump 305 rotates along the rotation position with the groove 301, and the rear end of the second vehicle to be transported 6 is flipped upward, reducing the space occupied on the vehicle body 2.

[0031] like Figure 1 , 2As shown in Figures 3 and 4, the support structure 9 includes a first crossbeam 901, which is fixedly connected to the interior of the rear end 8. A second connecting seat 902 is fixedly connected to the center of the rear end face of the first crossbeam 901. A third hydraulic cylinder 903 is rotatably connected to the rear end face of the second connecting seat 902. A second crossbeam 904 is fixedly connected to the center of the rear end face of the rear end face of the rear end face of the second crossbeam 904. A channel 905 is opened at the center of the rear end face of the second crossbeam 904. The output end of the third hydraulic cylinder 903 passes through the channel 905 and extends to the rear end of the second crossbeam 904. A third connecting seat 906 is rotatably connected to the end of the third connecting seat 906. A third crossbeam 907 is fixedly connected to the rear end face of the third connecting seat 906. The third crossbeam 907 is located near the front end face of the third crossbeam 907. Runway slabs 908 are fixedly connected to both sides. Runway grooves 909 are opened on the rear end face of the second crossbeam 904 at the front end of the two runway slabs 908. Grounding runways 910 are fixedly connected to the rear end face of the third crossbeam 907 at the rear end of the two runway slabs 908. By controlling the extension of the third hydraulic cylinder 903, the third hydraulic cylinder 903 pushes the third crossbeam 907 to move to the rear end, so that the two runway slabs 908 move to the rear end along the two runway grooves 909. Due to gravity, the rear end of the third crossbeam 907 rotates slightly downward, and the front end of the two runway slabs 908 is supported inside the two runway grooves 909, so that the grounding runway 910 contacts the ground, making it convenient for the vehicle to be transported to drive onto the vehicle body 2.

[0032] Frames 10 are fixedly connected to both sides of the inner wall of the vehicle body 2 near the front. First hydraulic cylinders 11 are fixedly connected inside the two frames 10, so that the two first hydraulic cylinders 11 can extend and the end support plates can support the ground to support the front end of the vehicle body 2.

[0033] Working principle: During use, by controlling the extension of the third hydraulic cylinder 903, the third hydraulic cylinder 903 pushes the third crossbeam 907 to move to the rear end, causing the two runway plates 908 to move to the rear end along the two runway grooves 909. Due to gravity, the rear end of the third crossbeam 907 rotates slightly downward, and the front ends of the two runway plates 908 are supported inside the two runway grooves 909, so that the grounding runway 910 contacts the ground. The first vehicle 5 to be transported is driven to the upper front of the vehicle body 2 via the two grounding runways 910 and the runway plates 908. Then, the second vehicle 6 to be transported is driven to the upper end of the lifting structure 3. By controlling the extension of the two second hydraulic cylinders 303, the two second hydraulic cylinders 303 push the two first connecting seats 304 to flip upward. The aircraft jump 305 rotates along the rotation position of the groove 301, flipping the rear end of the second transport vehicle 6 upwards. Then, the third transport vehicle 7 is driven to the rear of the groove 301 and the upper rear of the vehicle body 2. After fixing the first transport vehicle 5, the second transport vehicle 6, and the third transport vehicle 7, the third hydraulic cylinder 903 is controlled to retract. The third hydraulic cylinder 903 pulls the third crossbeam 907 to the front, and the two runway plates 908 enter the two runway slots 909. The third crossbeam 907 is stored in the rear of the second crossbeam 904. The third crossbeam 907 is under tension, which drives the two touchdown runways 910 to flip upwards, so that the vehicle body 2 can drive normally after storage.

[0034] After being transported to the designated location, the third hydraulic cylinder 903 is extended to open the third vehicle 7, the second vehicle 6, and the first vehicle 5 off the vehicle body 2, and then the support structure 9 is retracted to complete the transportation.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
