[0036] Embodiment 2

[0037] The solution in the first embodiment is further introduced below in combination with a specific working method, as described below for details:

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the transverse transmission structure includes a belt servo motor 23, and the output end of the belt servo motor 23 is connected to a belt transmission wheel 21, and a transverse transmission belt 22 is arranged on the surface of the belt transmission wheel 21, and a belt fixing part 20 is fixed on one side of the transverse transmission belt 22, and auxiliary support limit grooves 14 are provided at the connection between the belt fixing part 20 and the middle plate 11 of the assembly platform and the top plate 12 of the assembly platform.

A vertical limit guide slot 6 is provided at the connection between the load-bearing plate 9 and the lifting platform body 7. The load-bearing plate 9 is lifted and lowered on the lifting platform body 7 through the vertical limit guide slot 6. A manned protective fence 10 is welded on the top of the load-bearing plate 9, and infrared distance sensors 8 are installed on the left and right sides of the bottom of the load-bearing plate 9. The servo motor on the lifting platform body 7 is started, and the servo motor drives the active gear 19 to rotate, and drives the driven gear 17 to rotate through the transmission chain 18. At this time, the load-bearing plate 9 is lifted and lowered on the lifting platform body 7. At the same time, the distance between the load-bearing plate 9 and the ground is measured by the infrared distance sensor 8. The corresponding servo motor can be automatically controlled by the PLC controller, so that the height of the load-bearing plate 9 is adjusted to the required working height.

[0040] like Figure 6 As shown, as a preferred embodiment, based on the above method, further, a multi-layer support movable assembly platform directional connection structure includes a directional connection plate 13 installed on the right side of the assembly platform top plate 12, and a directional connection limit shaft 25 arranged on the right side of the assembly platform top plate 12;

[0042] From the above, we can know that:

[0043] The present invention aims at the following technical problems: most of the existing aircraft assembly platforms are fixed and cannot be moved, which makes it inconvenient for aircraft to enter and exit, and the aircraft assembly platform generally has only two layers and cannot accommodate different working positions in the height direction of the aircraft; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0044] When the aircraft needs to be assembled, the required parts and tools can be transported to the assembly platform. One end of the parts transfer plate 5 is in contact with the ground, and the transport trolley can be directly moved to both sides of the bottom plate 2 of the assembly platform. Through the escalator installed on the side, the assembler can climb to the top of the middle plate 11 of the assembly platform and the top plate 12 of the assembly platform, and select the lifting platform body 7 in a suitable position according to the working position. There are four groups of lifting platform bodies 7 installed on the assembly platform before and after. The personnel stand on the load-bearing plate 9 and start the belt servo motor 23. The belt servo motor 23 drives the belt transmission wheel 21 to rotate, and drives the belt fixing part 20 to move left and right through the transverse transmission belt 22. At this time, the belt fixing part 20 slides in the external auxiliary support limit groove 14 to adjust the transverse position of the lifting platform body 7. When the height of the lifting platform body 7 needs to be adjusted, , start the servo motor on the lifting platform body 7, the servo motor drives the active gear 19 to rotate, and drives the driven gear 17 to rotate through the transmission chain 18. At this time, the load-bearing plate 9 is lifted and moved on the lifting platform body 7. At the same time, the distance between the load-bearing plate 9 and the ground is measured by the infrared distance sensor 8. The corresponding servo motor can be automatically controlled by the PLC controller, so that the height of the load-bearing plate 9 is adjusted to the required working height. The motor is installed on the directional transmission roller 4, which can drive the entire assembly platform to move left and right on the ground directional transmission guide rail 1, which is convenient for assembling the aircraft. Even after the assembly is completed, the assembly platform can be directly moved to facilitate the movement of the aircraft. If the aircraft is long, the directional connection plate 13 on one set of assembly platforms can be placed on the directional connection limit shaft 25 of another set of assembly platforms, so that the two sets of assembly platforms are connected head to tail to achieve rapid assembly;

[0045] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0046] The assembly platform of the present invention is provided with a three-layer structure of the assembly platform bottom plate 2, the assembly platform middle plate 11, and the assembly platform top plate 12, which can expand the height of the assembly platform to adapt to working positions of different heights. Since the heights of different aircraft models are different, different aircraft models can be compatible. In addition, the assembly platform is moved left and right on the ground directional transmission guide rail 1 through the directional transmission roller 4 at the bottom of the assembly platform bottom plate 2, which is convenient for moving the entire assembly platform and easy to avoid the aircraft.

[0047] The present invention can drive the belt conveyor wheel 21 to rotate under the drive of the belt servo motor 23 by setting the transverse conveying structure, so as to drive the belt fixing member 20 to move left and right through the transverse conveying belt 22, and can quickly adjust the position of the lifting platform body 7. When the assembler needs to move horizontally, it can save time and move quickly. In addition, auxiliary support limit grooves 14 are provided on the surfaces of the middle plate 11 of the assembly platform and the top plate 12 of the assembly platform, which can improve the stability of the belt fixing member 20 when moving;

[0048] The manned lifting structure of the present invention can drive the driving gear 19 to rotate under the action of the servo motor, and then drive the driven gear 17 to rotate through the transmission chain 18, so that the carrying plate 9 can be lifted and moved on the lifting platform body 7, and an infrared distance sensor 8 is arranged at the bottom of the carrying plate 9 to measure the distance between the carrying plate 9 and the ground, and the height of the carrying plate 9 can be adjusted to the required working height. The assembler can stand on the carrying plate 9 to lift and lower, and the horizontal transmission structure can be used to realize the rapid adjustment of the position of the assembler;

[0049] The directional connection structure of the present invention can quickly connect the left and right ends of two groups of assembly platforms, and can complete the direct and rapid assembly of the assembly platforms, so that the size of the assembly platforms is adapted to the length of the aircraft. When not in use, the directional connection plates 13 can be rotated to detach from each other, which is convenient to use.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
