Description

Technical Field

[0001] This application relates to the field of aviation manufacturing, in particular to a fully automatic track device for narrow spaces in wing boxes. Background Art

[0002] A fully automatic track device for narrow spaces in wing boxes has strong applicability in aircraft assembly, track laying, or transportation of other components.

[0003] Currently, for a certain type of aircraft wing box product, its size is large, the internal space is narrow and the structure is complex. The through-hole size of the wing rib is only 600mm x 300mm. Operators must enter the interior of the wing box to perform operations such as gluing and riveting. To facilitate the operators to enter the interior of the wing box to work, tracks are laid at the through-hole positions between the wing ribs as passageways for personnel. However, during the laying process, the track modules need to be closely arranged and recessed and installed at the wing box rib plates without any movement. If manual laying is adopted, multiple personnel are required to cooperate inside and outside the wing box for installation. The internal structure and environment of the wing box are uncontrollable, posing certain risks. Therefore, there is an urgent need for a fully automatic track device for narrow spaces in wing boxes, which can be automatically installed at the through-holes of the wing ribs inside the wing box, can flexibly and quickly lay the track modules in place, and at the same time, can also transport other components, having versatility and economy. Summary of the Invention

[0004] To solve the above problems, this application provides a fully automatic track device for narrow spaces in wing boxes, enabling the track modules to be quickly installed at the through-holes of the wing ribs, truly realizing the functions of quick installation and automation of the track modules.

[0005] To achieve the above objectives, the following technical solutions are adopted in this application:

[0006] A fully automatic track device for narrow spaces in wing boxes includes a track plate, a drive frame assembly, a V-shaped drive wheel assembly, a climbing leg assembly, a web, and a power supply. The track plate includes a bottom plate and guide rails. Two guide rails are arranged side by side and installed on the two side edges of the upper surface of the bottom plate. A T-shaped hole is provided at the front end of the bottom plate. The drive frame assembly is embedded and installed in the T-shaped hole at the front end of the lower surface of the bottom plate. The V-shaped drive wheel assembly is fixedly installed in the middle of the lower surface of the bottom plate. The climbing leg assembly is installed at the rear part of the lower surface of the bottom plate. The power supply is fixedly installed on one side of the middle of the lower surface of the bottom plate. The web envelopes the drive frame assembly, the V-shaped drive wheel assembly, the climbing leg assembly, and the power supply and is connected to the bottom plate to form a whole vehicle structure. The drive frame assembly and the V-shaped drive wheel assembly rotate synchronously to drive the whole vehicle structure to move forward along the guide rails. When reaching the pre-installation position, the climbing legs in the climbing leg assembly extend forward. Taking the ends of the climbing legs as the fulcrums, the whole vehicle structure is slid forward. After sliding to the designated position, the climbing legs are retracted to complete the track laying.

[0007] Furthermore, the drive frame assembly includes a drive frame, a synchronous pulley fixing frame, a drive motor bracket, a first synchronous pulley group, a second synchronous pulley group, a third synchronous pulley group, a drive motor, and a synchronous belt. The drive frame, the synchronous pulley fixing frame, and the drive motor bracket are arranged side by side at the front end of the track slab along the traveling direction of the vehicle body. The transmission shaft of the first synchronous pulley group passes through the shaft hole above the drive frame and is fixed with a bearing. One end of the second synchronous pulley group is fixed to the middle of the shaft of the first synchronous pulley group, and the other end is installed and fixed below the drive frame. One end of the third synchronous pulley group is installed on the synchronous pulley fixing frame, and the other end is fixed to the drive motor bracket. The drive motor shaft passes through the shaft hole of the drive motor bracket and is connected to the third synchronous pulley group. The synchronous belt sequentially bypasses the first synchronous pulley group, the second synchronous pulley group, and the third synchronous pulley group. The drive motor drives the third synchronous pulley group to rotate, driving the second synchronous pulley group to rotate, and driving the first synchronous pulley group to rotate.

[0008] Furthermore, the V-shaped drive wheel assembly includes a V-shaped wheel bracket, a V-shaped drive wheel, a V-shaped drive wheel shaft, a synchronous pulley, a V-shaped drive wheel motor, and a V-shaped drive wheel motor seat. Two V-shaped wheel brackets are symmetrically installed in the middle of the track slab. V-shaped drive wheels are installed on both sides of the V-shaped drive wheel shaft and fixed at the shaft holes of the V-shaped wheel brackets. One end of the synchronous pulley passes through the V-shaped drive wheel shaft, and the other end is connected to the drive shaft of the V-shaped drive wheel motor. The V-shaped drive wheel motor is fixed on the V-shaped drive wheel motor seat, and the V-shaped drive wheel motor seat is fixedly installed on the track slab, forming a triangular distribution with the V-shaped wheel bracket.

[0009] Furthermore, the leg assembly includes a leg motor, a leg motor seat, a first synchronous belt pulley, a horizontal shaft, two horizontal shaft brackets, two second synchronous belt pulleys, two leg brackets, two short shafts, and two legs. The leg motor seat is fixedly installed on the track slab, and the leg motor is installed on the leg motor seat through a bearing. The first synchronous belt pulley consists of two small synchronous pulleys and a small synchronous belt. One end of the first synchronous belt pulley is connected to the shaft of the leg motor, and the other end is fixedly installed on the horizontal shaft. Both ends of the horizontal shaft pass through the middle holes of the two horizontal shaft brackets and are fixed to the lower surface of the bottom plate of the track slab. One end of each of the two second synchronous belt pulleys is connected to the two horizontal shafts respectively, and the other end respectively passes into the two short shafts. The two short shafts are symmetrically fixed at the through holes of the leg brackets. The two legs are respectively fixed to the two short shafts through bearings. The leg motor drives the first synchronous belt pulley to rotate, driving the horizontal shaft to rotate, and then driving the two second synchronous belt pulleys to rotate, enabling the legs to rotate 360° around the short shafts. When the end of the leg rotates to abut against the surface of the product, it serves as a fulcrum point. The entire vehicle body structure slides forward with the fulcrum point as the pivot and the leg as the radius. After reaching the specified position, the legs are retracted to complete the track laying.

[0010] The beneficial effects of this application are as follows: In view of the need for automation during the laying process of the track device, a fully automatic track device for narrow spaces in the wing box proposed in this application adopts a track device structure with an independent power system, realizing automatic track laying without relying on manual labor and having a high degree of automation. Compared with the track laying scheme using a bridge girder erection machine, the laying efficiency is higher. The track slab of the track device is in the form of a strut structure, thus solving the problem that the track device may fall due to the front end being suspended during the track laying process. The use of a multi-pulley cooperation structure solves the problem of achieving continuous transmission between independent track devices, occupying less space and having stronger adaptability to the gaps between track devices. The "V"-shaped track structure ensures good smoothness when the wheels pass through the gaps between track devices. In addition, the guiding effect of the "V"-shaped inclined plane of this structure ensures that the rear end of the newly laid track device is completely aligned with the front end of the already laid track.
