In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the following description, with reference to the direction in fig. 1 as a direction, forward is taken to the left along the drawing sheet surface, backward is taken to the right along the drawing sheet surface, upward is taken to the upper along the drawing sheet surface, and downward is taken to the lower along the drawing sheet surface.
As shown in FIG. 1, the invention provides a large-tonnage drop-and-pull transport vehicle, which comprises a tractor 1, a trailer 2, a mechanical gooseneck 3, a cargo box 25 and a jacking system 2. The tractor 1 mainly provides traction force and provides a power source for lifting the mechanical gooseneck 3, and the power source is specifically a driving oil cylinder 11. The gearbox is provided with a power takeoff, so that the gear pump can be conveniently installed to take power. The main beam of the trailer 2 adopts a through-length box type structure, and the cross beam adopts an I-shaped beam to form an integral frame structure, so that the structural strength of the trailer frame is improved. Four groups of V-shaped brackets are designed on the upper part of the platform and are used for transporting steel coils.
The mechanical gooseneck 3 is Z-shaped, the front end of the mechanical gooseneck is hinged with a piston rod of the driving oil cylinder 11, and the rear end of the mechanical gooseneck is in butt joint with or separated from the trailer 2 along with the extension and contraction of the piston rod. Specifically, the bottom of the front end of the trailer 2 is provided with a traction seat 22, and when a piston rod of the driving oil cylinder 11 stretches, the rear end of the mechanical gooseneck 3 can be hooked on the traction seat 22 to realize connection and can also be separated from the traction seat 22 to realize separation of the tractor 1 and the trailer 2.
The trailer 2 is provided with a cargo box 25, the rear end of the cargo box 25 is hinged with two turnover seats at the rear end of the trailer 2. The jacking system 21 comprises a plurality of oil cylinders and a hydraulic control system, the oil cylinders are fixedly arranged at the front end of the container 25, piston rods of the oil cylinders are hinged with the front end of the trailer 2, and the hydraulic control system controls the plurality of oil cylinders to be synchronously jacked through a synchronous motor. Specifically, the number of the oil cylinders is two, the synchronous motors comprise two motors connected with the synchronous shaft, oil outlets of the two motors are respectively connected with rodless cavities of the two oil cylinders, and the stroke of piston rods of the two oil cylinders is consistent in the jacking process of the container 25.
