[0027] As Figure 1 — Figure 2 shown, a cart for transporting large aircraft components includes a bracket 1, a pushing and pulling device 2, a positioning unit 3 and a locking unit 4;

[0028] The pushing and pulling device 2 is arranged on the bracket 1 and is used for pushing and pulling the large component transportation bracket 5 on the bracket 1;

[0029] The positioning unit 3 is arranged on the bracket 1 and is used for positioning the position when the bracket 1 is connected to the trailer 6;

[0030] The locking unit 4 is arranged on the bracket 1 and is used for locking and connecting the bracket 1 and the trailer 6;

[0031] The trailer 6 is an aircraft large-component transport trailer 6.

[0032] It should be noted that the pushing and pulling device 2 is a pushing and pulling oil cylinder, and can also be an electric cylinder, a pneumatic cylinder or a lead screw nut mechanism with pushing and pulling functions, etc.;

[0033] The pushing and pulling device 2 is installed in the middle of the bracket 1. The pushing and pulling device 2 has two functions: the end of the pushing and pulling oil cylinder is connected to the connecting ear plate of the trailer 6, and the oil cylinder is contracted, so that the trolley is pulled towards the trailer 6 to realize the docking of the trailer 6 and the trolley; then the end of the pushing and pulling oil cylinder is connected to the ear plate of the large-component transport bracket 5, and through the pushing or pulling of the oil cylinder, the large-component transport bracket 5 is moved towards the trailer 6 or the trolley direction to complete the transfer of the large-component transport bracket 5.

[0034] In this embodiment, the positioning unit 3 is a trolley guide rod, and a positioning hole for inserting the trolley guide rod is provided on the trailer 6.

[0035] The structure of the trailer can refer to another patent for an aircraft large-component transport trailer structure applied simultaneously.

[0036] It should be noted that the number of the trolley guide rods is two, and the front end of the trolley guide rod is a frustum structure.

[0037] In this embodiment, the locking unit 4 is a pin oil cylinder, and a pin hole for pin-connecting the pin oil cylinder is provided on the trailer 6. The locking unit 4 can also be a pin electric cylinder, a pin pneumatic cylinder or a manual pin, etc.;

[0038] It should be noted that the left side wall of the trailer 6 has a hollow structure. During actual use, the pin oil cylinder can extend into the hollow structure, and the telescopic end of the pin oil cylinder extends upward and penetrates into the pin hole on the trailer 6, so as to realize the locking connection between the bracket 1 and the trailer 6.

[0039] In this embodiment, limiting rods are arranged on the front side, rear side and left side of the bracket 1. The positioning unit 3 and the locking unit 4 are both arranged on the right side of the bracket 1, and the telescopic direction of the pushing and pulling device 2 is the left-right direction.

[0040] In this embodiment, it further includes a trolley body 7 and a lifting mechanism 8. The bracket 1 is located above the trolley body 7, and a lifting mechanism 8 is installed between the bracket 1 and the trolley body 7. The lifting mechanism 8 is used for lifting the bracket 1.

[0041] In this embodiment, the lifting mechanism 8 includes screw jacks 8-1 installed at the four corners of the bracket 1. The four screw jacks 8-1 are sequentially connected by a synchronous shaft 8-2, and at least one of the screw jacks 8-1 is equipped with a driving motor 8-3.

[0042] It should be noted that the lifting of the bracket 1 is performed by the screw jacks 8-1. The four screw jacks 8-1 are driven by one motor 8-3, and the synchronous shaft 8-2 connects and synchronously drives the four screw jacks 8-1. When the bracket 1 approaches the trailer 6, the trolley guide rod on the trolley aligns with the positioning hole on the trailer 6. If the trailer 6 and the cargo plane of the bracket 1 are inconsistent due to the tire pressure of the trailer 6, the screw jacks 8-1 are used to adjust the height of the cargo plane of the bracket 1 so that the trolley guide rod aligns with the positioning hole. Then, the piston rod of the push-pull device 2 is extended, and the end of the piston rod is connected to the connecting ear plate of the trailer 6 with a pin. The push-pull device 2 is contracted, so that the trolley is pulled towards the trailer 6, realizing the docking of the trailer 6 and the trolley.

[0043] As Figure 3 and Figure 4 shown, when the present utility model is in use, it is positioned through the trolley guide rod and the trailer 6. Then, the end of the push-pull device 2 is connected to the connecting ear plate of the trailer 6, and the push-pull device 2 is contracted, so that the trolley is pulled towards the trailer 6, realizing the docking of the trailer 6 and the trolley. Then, the telescopic end of the pin cylinder extends upwards and penetrates into the pin hole on the trailer 6, thereby realizing the locking connection between the bracket 1 and the trailer 6. Finally, the end of the push-pull device 2 is connected to the ear plate of the large component transportation bracket 5, and the large component transportation bracket 5 is moved towards the trailer 6 through the push-pull device 2, completing the transfer of the large component transportation bracket 5.

[0044] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the present utility model. Any simple modification, change, and equivalent structural change made to the above embodiments according to the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
