[0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a high-barrier, high-box car tailgate crawlway type boarding ramp, which combines the crawlway and the tailgate into one, convenient for loading and unloading of various goods, and solves the problems of needing to install the crawlway first, only being able to load and unload tracked or wheeled mechanical equipment, and the trouble and inconvenience of manual loading and unloading.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A high-rail, high-box car tailgate climbing boarding ramp, comprising two climbing ramps, two tailgates, two hydraulic cylinders installed on the truck compartment, two hydraulic pumps respectively connected to the two hydraulic cylinders, two hydraulic switches control-connected to the two hydraulic pumps, two hinged shafts, and four climbing ramp supports. The tailgate is provided with a through groove adapted to the climbing ramp, the climbing ramp is arranged in the through groove, the bottom of the climbing ramp is movably hinged to the end of the truck compartment through the hinged shaft, one end of each of the two climbing ramp supports is fixedly connected to the bottom end of one of the climbing ramps, and the other end is connected to the front end of the telescopic rod of the hydraulic cylinder, and an angle of 150 degrees is provided between the climbing ramp support and the climbing ramp.

[0006] Preferably, the two tailgates are movably connected via a heavy-duty lock, and a sealing strip is also provided at the connection.

[0007] Preferably, a plurality of manger hooks are correspondingly provided on the two tailgates.

[0008] Preferably, the number of the climbing supports is 4, two of which are connected to the front end of the telescopic rod of one of the hydraulic cylinders, and the other two are connected to the front end of the telescopic rod of the other hydraulic cylinder.

[0009] The beneficial effects of the present invention are as follows: the present design combines the crawlway and the tailgate into one, so that the crawlway can move with the vehicle, and there is no need to install the crawlway before loading and unloading goods. It is also convenient to load and unload a variety of goods, greatly increasing the types of goods that can be loaded and unloaded. The tailgate is controlled to be lowered or closed by hydraulic means, which facilitates the loading and unloading of goods and allows workers to load and unload faster and more efficiently.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 to Figure 2As shown, a high-rail, high-box car tailgate climbing boarding ramp comprises two climbing ramps 2, two tailgates 1, two hydraulic cylinders 8 installed on a truck compartment 7, two hydraulic pumps 9 respectively connected to the two hydraulic cylinders 8, two hydraulic switches controlled and connected to the two hydraulic pumps 9, two hinged shafts 3, and four climbing ramp supports 10. A through groove adapted to the climbing ramp 2 is provided on the tailgate 2, and the climbing ramp 2 is arranged in the through groove, so that the climbing ramp 2 can form an integrated structure with the tailgate 1, which is conducive to loading and unloading a variety of goods and convenient for the climbing ramp 2 to drive the tailgate 1 to rotate together. The bottom is movably hinged to the end of the truck's carriage 7 through an articulated shaft 3. One end of each of the two climbing track supports 10 is fixedly connected to the bottom end of a climbing track 2, and the other end is connected to the front end of the telescopic rod of the hydraulic cylinder 8. An angle of 150 degrees is set between the climbing track support 10 and the climbing track 2. The angle of the angle can be adjusted according to actual needs, so that when the hydraulic pump 9 controls the hydraulic cylinder 8 to retract or extend, the climbing track support 10 is driven to rotate around the articulated shaft 3, driving the climbing track 2 and the tailgate 1 to be lowered and opened, or lifted to close the door, so that workers can load and unload faster and more effectively.

[0017] Furthermore, the two tailgates 1 are movably connected via a heavy-duty lock 6 , and a sealing strip 5 is also provided at the connection.

[0018] Furthermore, a plurality of horse trough hooks 4 are correspondingly provided on the two tailgates 1 for use in connection with high railings or high compartments of the compartments on both sides.

[0019] When in use, press the hydraulic switch, the hydraulic pump controls the telescopic rod of the hydraulic cylinder to retract or extend, drive the climbing track support 10 to rotate around the hinge shaft 3, drive the climbing track 2 and the tailgate 1 to be lowered and opened, or lifted to close the door, and the workers can load and unload goods when the tailgate 1 is lowered and opened.

[0020] The design of the present invention combines the crawlway and the tailgate into one, so that the crawlway can move with the vehicle. There is no need to install the crawlway before loading and unloading goods. It is also convenient to load and unload a variety of goods, greatly increasing the types of goods that can be loaded and unloaded. The tailgate is controlled to be lowered or closed by hydraulic means, which is convenient for workers to load and unload faster and more efficiently, and has good practical value.

[0021] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
