Description

Technical Field

[0001] The utility model belongs to the technical field of transportation machinery, and particularly relates to a transportation trailer structure for large aircraft components. Background Art

[0002] Chinese Utility Patent CN219468545U discloses a bracket for transporting an aircraft tail fin. The aircraft tail fin can be installed on the transportation bracket and then placed in a trailer for transportation. However, it is found in the implementation process that there is currently no good transportation trailer structure. After the existing trailer is placed with the transportation bracket, it is not stable enough. The main reason is that the existing trailer does not have a special structure for fixing the transportation bracket, which poses a safety hazard when transporting large aircraft components such as aircraft tail fins.

[0003] Currently, there is a lack of a transportation trailer structure for specially placing large aircraft component transportation brackets such as tail fin transportation brackets. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a transportation trailer structure for large aircraft components in view of the deficiencies in the above-mentioned prior art, so as to solve the problem that the large component transportation bracket is not stable enough after being placed in the trailer to a certain extent.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is: a transportation trailer structure for large aircraft components, including a base and two limit guide rods arranged on the base. The two limit guide rods are arranged in parallel, and the distance between the two limit guide rods is adapted to the width of the large component transportation bracket. A plurality of pressing devices are arranged on each limit guide rod, and the pressing devices are used to press the large component transportation bracket.

[0006] In the above transportation trailer structure for large aircraft components, a plurality of openings are arranged on the base. The positions and numbers of the openings are adapted to the positions and numbers of the traveling wheels on the large component transportation bracket. A lifting device is arranged in the opening, and a supporting block is installed at the telescopic end of the lifting device; the opening can be used for the traveling wheels on the large component transportation bracket to be clamped;

[0007] When the telescopic end of the lifting device extends out, the supporting block fills the opening and the top surface of the supporting block is flush with the surface of the base.

[0008] In the above transportation trailer structure for large aircraft components, the lifting device is a lifting oil cylinder.

[0009] In the above transportation trailer structure for large aircraft components, the pressing device is a pressing oil cylinder.

[0010] For the above aircraft large-component transportation trailer structure, a pin hole is provided on the left edge of the base; the limit guide rod is perpendicular to the left edge of the base, and the pin hole is used for pin connection with the transportation cart.

[0011] For the above aircraft large-component transportation trailer structure, a positioning hole is provided on the left side wall of the base, and the positioning hole is used for positioning when connecting with the transportation cart.

[0012] Compared with the prior art, the present invention has the following advantages: By arranging two limit guide rods to limit both sides of the large-component transportation bracket and then using a pressing device to press, the large-component transportation bracket has sufficient stability after entering the trailer.

[0013] The technical solution of the present invention will be further described in detail below with reference to the drawings and embodiments. Description of the Drawings

[0025] As Figure 1As shown in FIG. 4, a structure of an aircraft large-component transport trailer includes a base 1 and two limit guiding rods 2 arranged on the base 1. The two limit guiding rods 2 are arranged in parallel, and the distance between the two limit guiding rods 2 is adapted to the width of the large-component transport bracket 3. A plurality of pressing devices 4 are arranged on each limit guiding rod 2, and the pressing devices 4 are used to press the large-component transport bracket 3.

[0026] In this embodiment, a plurality of openings 5 are arranged on the base 1. The positions and numbers of the openings 5 are adapted to the positions and numbers of the walking wheels on the large-component transport bracket 3. A lifting device 6 is arranged in the opening 5, and a supporting block 7 is installed at the telescopic end of the lifting device 6; the opening 5 can be used for the walking wheels on the large-component transport bracket 3 to be clamped; when the telescopic end of the lifting device 6 extends out, the supporting block 7 fills the opening 5 and the top surface of the supporting block 7 is flush with the surface of the base 1.

[0027] In this embodiment, the lifting device 6 is a lifting oil cylinder, and it can also be a lifting electric cylinder or a lifting pneumatic cylinder.

[0028] It should be noted that in practice, there are four walking wheels under the large-component transport bracket 3, which are distributed at the four corners of the large-component transport bracket 3. Correspondingly, four openings 5 are opened on the base 1, which are distributed at positions close to the ends of the two limit guiding rods 2. When the large-component transport bracket 3 enters the trailer, the walking wheels are exactly on the supporting block 7, and the supporting block 7 descends to make the walking wheels clamped in the openings 5.

[0029] In this embodiment, the pressing device 4 is a pressing oil cylinder, and it can also be other devices with pressing functions. The pressing oil cylinder is a 90-degree rotating automatic clamping hydraulic corner oil cylinder, which is an existing technology (can be directly purchased), and the detailed operation principle is not introduced in detail here. Two pressing oil cylinders are arranged on each limit guiding rod 2.

[0030] In this embodiment, a pin hole 8 is opened on the left edge of the base 1; the limit guiding rod 2 is perpendicular to the left edge of the base 1, and the pin hole 8 is used for pin connection with the transport trolley 9.

[0031] In this embodiment, a positioning hole 10 is opened on the left side wall of the base 1, and the positioning hole 10 is used for positioning when connecting with the transport trolley 9.

[0032] As Figure 5 and Figure 6As shown in the figure, when the utility model is in use, first, the transport cart 9 is positioned by the cart guide rod and the trailer. Then, the end of the push-pull oil cylinder of the transport cart 9 is connected to the connecting ear plate of the trailer. The push-pull oil cylinder is contracted, so that the transport cart 9 is pulled towards the trailer to realize the docking of the trailer and the cart. Then, the telescopic end of the pin oil cylinder extends upward and penetrates into the pin hole 8 on the trailer, thereby realizing the locking connection between the bracket and the trailer. Finally, the end of the push-pull oil cylinder is connected to the ear plate of the large component transport bracket 3, and the large component transport bracket 3 is moved towards the trailer direction through the push-pull oil cylinder to complete the transfer of the large component transport bracket 3.

[0033] When the large component transport bracket 3 enters the trailer, the lifting oil cylinder drives the supporting block 7 to descend, so that the traveling wheels of the large component transport bracket 3 descend into the opening 5 to form a clamping. Then, the upper end of the pressing oil cylinder rotates 90° and then contracts to press both sides of the large component transport bracket 3, thereby realizing the fixation of the large component transport bracket 3 on the trailer base 1.

[0034] The above are only the preferred embodiments of the present utility model, and do not impose any limitations on the present utility model. Any simple modifications, changes, and equivalent structural changes 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.
