Technical Field

[0001] This utility model relates to the technical field of aircraft component transport racks, and more specifically to a general-purpose aircraft front wheel hub assembly packaging and transport rack. Background Technology

[0002] General aviation aircraft refers to all aircraft used for civil aviation activities other than scheduled passenger and cargo transport aircraft. Their operational scope covers industrial, agricultural, forestry, fishery, and construction operations, as well as non-public transport missions such as medical and health services, disaster relief, meteorological observation, marine monitoring, education and training, cultural and sports activities, and tourism. Existing general aviation aircraft have many components, and the production and assembly bases for these components are not located in the same place. Therefore, appropriate transport racks need to be designed for their transport. For example, the front wheel hub of a general aviation aircraft includes a left front wheel hub and a right front wheel hub. Both the left and right front wheel hubs consist of two hubs and an axle positioned between them. To prevent collisions between the wheel hubs, a corresponding wheel hub transport rack needs to be designed, requiring convenient installation and transportation while also requiring the two front wheel hubs to be installed separately. Utility Model Content

[0022] Example: See Figures 1 to 3 As shown, a packaging and transport rack for a general-purpose aircraft front wheel hub assembly includes a rectangular transport base frame. The transport base frame includes two sets of bottom beam frames 1 arranged on the left and right, which are fixedly connected together by several transverse connecting beams 2. Vertical support frames 3 are fixedly connected to the ends of the bottom beam frames 1. Left and right opposite wheel hub support frames 4 are fixedly connected to the support frames 3 on both sides of the transport base frame frame by bolt assemblies 5. The wheel hub support frame 4 includes a vertical support beam 41 fixed to the support frame 3. Two horizontal support beams 42 distributed vertically are fixedly connected to the vertical support beam 41. One side of the end of the horizontal support beam 42 is formed with a beveled cut 422 and the other side is formed with a U-shaped latch 421. Vertical connecting pins 6 are inserted into the horizontal support beam 42.

[0023] Reinforcing plates 43 are fixed to the front and rear side walls of the horizontal support beam 42 near the end of the vertical support beam 41, respectively. The reinforcing plates 43 are welded and fixed to the front and rear end faces of the vertical support beam 41. The upper and lower ends of the vertical support beam 41 are respectively formed with bolt through holes 411 opposite to the bolt assembly 5. The reinforcing plates 43 can improve the load-bearing strength of the entire wheel hub support frame 4. At the same time, the bolt assembly 5 facilitates the installation and disassembly of the wheel hub support frame 4.

[0024] The upright frame 3 includes a vertical column 31. Diagonal supports 32 are fixedly connected to the front and rear ends of the middle and lower parts of the column 31, respectively. The lower ends of the diagonal supports 32 and the lower ends of the column 31 are both fixedly connected to the bottom beam frame 1. This is the specific structure of the upright frame 3, which mainly ensures that the upright frame 3 has sufficient support strength. Several triangular support plates are fixedly connected to the side wall of the bottom of the column 31 near the transport bottom frame seat. The support plates are fixedly connected to the bottom beam frame 1.

[0025] The bottom beam frame 1 includes two horizontal bottom beams distributed in front and rear. Several longitudinal bottom beams are fixedly connected to the lower end of the horizontal bottom beams. The two ends of the horizontal connecting beam 2 respectively abut against the inner side wall of the horizontal bottom beam and are fixedly connected to the horizontal bottom beam. The above is the distance structure of the bottom beam frame 1.

[0026] The connecting pins 6 on the wheel hub support frames 4 on both sides of the transport base are set in opposite directions; the connecting pins 6 are T-shaped cylindrical pins, and the tail end of the connecting pin 6 is formed with connecting holes that penetrate the two opposite outer walls of the connecting pin 6, and cotter pins can be inserted into the connecting holes; this transport frame is used to load the left front wheel hub and the right front wheel hub, one set of front wheel hubs is mounted upright and the other set is mounted upside down, so the installation directions of their connecting pins 6 are different.

[0027] like Figure 4 , 5 As shown, the vertical support beam 41 and the horizontal support beam 42 on the hub support frame 4 are both rectangular tubular components; an auxiliary support frame 7 is provided between the hub support frames 4 on both sides of the transport base frame.

[0028] The auxiliary support frame 7 includes two transverse square tubes 71. Each end of the square tube 71 has a beveled opening 711 that matches the beveled cut 422 on the transverse support beam 42. The beveled openings 711 at both ends of the square tube 71 abut against the beveled cut 422 of the transverse support beam 42. A transverse adjusting groove 711 is formed on the side wall of the square tube 71 near the beveled opening 711. L-shaped locking rods 76 are inserted into both ends of the square tube 71. Each locking rod 76 consists of a slider and a locking tongue. The locking tongue of the locking rod 76 extends out of the square tube 71 and is inserted into the transverse support beam 42 and onto the slider. A locking screw 77 is screwed in and inserted into the adjustment groove 711 of the square tube 71. The head of the locking screw 77 presses against the outer wall of the square tube 71. A vertical support rod 72 is fixed to the middle of the square tube 71. A longitudinal support rod 73 is fixed to the lower end of the vertical support rod 72. The longitudinal support rod 73 abuts against the upper end surface of the transverse connecting beam 2. Vertical connecting plates 74 are fixed to both ends of the longitudinal support rod 73. The connecting plates 74 are distributed on the front and rear sides of the transverse connecting beam 2 and are screwed with locking bolts 75. The ends of the locking bolts 75 press against the transverse connecting beam 2.

[0029] The auxiliary support frame 7 of this structure is mainly used to support the front wheel hub assembly after the front wheel hub assembly is loaded, so as to prevent one end of the wheel hub assembly 4 from being suspended. When installing the auxiliary support frame 7, the openings are first aligned to make the oblique opening 712 and the oblique cut 411 aligned. Then, the locking rod 76 is moved and inserted into the horizontal support beam 42 to make the square tube 71 connect the horizontal support beams 42 on both sides. Then, the vertical support rod 72 is used for the middle support. Finally, the locking bolt 75 is tightened to fix the position.

[0030] The locking tongue on the locking rod 76 is located on one side of the bayonet 421 on the horizontal support beam 42 and abuts against the inner wall of the horizontal support beam 42; the slider of the locking rod 76 abuts against the inner walls of the front and rear sides of the square tube 71 respectively.

[0031] Working principle: This structure is a packaging and transport frame for general-purpose aircraft front wheel hub assemblies. The structure of the transport frame is as follows: Figure 1 As shown, it is equipped with two pairs of hub support frames 4, which are used to load two sets of front wheel hub components. The axle on the front wheel hub component is inserted into the slot 411 of the crossbeam. At the same time, the two wheel hubs abut against the two crossbeams 41 respectively. The connecting pin 6 is inserted into the slot of the spoke part of the wheel hub and is inserted into the crossbeam 41 for connecting components such as cotter pins. Based on the connecting pin 6, the front wheel hub component can be suspended on the hub support frame 4, which can prevent it from falling off and can also be used to allow it to rotate; and the installation is convenient.

[0032] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
