[0026] As Figures 1-5 shown, an intermediate crossbeam structure for a port tractor includes a longitudinal beam assembly, an intermediate crossbeam assembly 4, and a plurality of pipeline bundles;

[0027] The longitudinal beam assembly includes a symmetrically arranged left longitudinal beam assembly 7 and a right longitudinal beam assembly 6, and both the left and right longitudinal beam assemblies are of box-shaped structures;

[0028] The intermediate crossbeam assembly 4 includes two channel-shaped crossbeams 41 and two crossbeam bottom plates 43. The openings of the two crossbeams 41 face each other and are fixed together. The two ends of each crossbeam 41 are respectively connected to the two crossbeam bottom plates 43, and the two crossbeam bottom plates 43 are respectively connected to the left longitudinal beam assembly 7 and the right longitudinal beam assembly 6;

[0029] The pipeline bundles are installed on the crossbeam 41 of the intermediate crossbeam assembly 4 through a bracket assembly.

[0030] In some embodiments, the left longitudinal beam assembly 7 and the right longitudinal beam assembly 6 have the same structure, and both include a longitudinal beam and an inner longitudinal beam seal plate. The longitudinal beam is in a C shape, and the inner longitudinal beam seal plate is welded to the inner side of the longitudinal beam. The inner longitudinal beam seal plate and the longitudinal beam cooperate to form a box-shaped structure, which can increase the overall structural strength. As Figure 5 shown, taking the right longitudinal beam assembly 6 as an example, it includes a right longitudinal beam 61 and a right inner longitudinal beam seal plate 62 welded to the inner side of the right longitudinal beam 61.

[0031] In some embodiments, as Figure 1 , Figure 2 shown, the two crossbeam bottom plates 43 are correspondingly welded to the inner longitudinal beam seal plates of the left longitudinal beam assembly 7 and the right longitudinal beam assembly 6, with high stability. At the same time, through holes that cooperate with each other are opened on the crossbeam bottom plates 43 and the inner longitudinal beam seal plates, facilitating the installation of the pipeline bundles.

[0032] In some embodiments, as Figure 2 , Figure 3 shown, square installation holes for installing the two crossbeams 41 are opened on the crossbeam bottom plates 43, improving the installation stability of the crossbeams 41 and the crossbeam bottom plates 43.

[0033] In some embodiments, both ends of the two crossbeams 41 are welded to the crossbeam bottom plate 43, which improves the structural strength of the intermediate crossbeam assembly 4. Additionally, a reinforcing rib 42 is welded between each crossbeam 41 and the crossbeam bottom plate 43, further enhancing the structural strength of the intermediate crossbeam assembly 4.

[0034] In some embodiments, as Figure 4 shown, chamfers are provided at the sharp corners of the crossbeam 41, and a triangular process hole 44 is formed by welding between the two crossbeams 41 and a crossbeam bottom plate 43. This process hole 44 is used to quickly discharge the electrocoating liquid during electrocoating, preventing the electrocoating liquid from accumulating in the cavity formed by the connection of the two trough-shaped crossbeams 41.

[0035] In some embodiments, as Figure 2 shown, the bracket assembly includes a bracket 3 mounted on the crossbeam 41 and a cable tie 2 mounted on the bracket 3. The cable harness is fastened by the cable tie 2. Threaded holes are tapped on the crossbeam 41, and the bracket 3 is fixed to the crossbeam 41 by bolts 8. The use of the bracket assembly facilitates the installation of the cable harness on the crossbeam 41.

[0036] In some embodiments, as Figure 1 、 Figure 2 shown, the cable harness includes a brake cable bundle 1 mounted on the front side of the intermediate crossbeam assembly 4 and a wire harness 5 mounted on the rear side of the intermediate crossbeam assembly 4. The brake cable bundle 1 is respectively installed on the front side of the crossbeam 41 and the wire harness 5 is installed on the rear side of the crossbeam 41 through the bracket assembly. The fixing effect is good, meeting the installation requirements of the pipelines and components of the fuel port tractor.

[0037] During installation, the two trough-shaped crossbeams 41 are welded into a cavity-shaped structure with their openings facing each other, and then the two crossbeam bottom plates 43 are symmetrically welded to both ends of the cavity-shaped structure. At the same time, reinforcing ribs 42 are welded between the crossbeam bottom plate 43 and the crossbeam 41, thus forming the intermediate crossbeam assembly 4;

[0038] The right longitudinal beam inner seal plate 62 is welded inside the right longitudinal beam 61 to form a box-shaped right longitudinal beam assembly 6. Similarly, a box-shaped left longitudinal beam assembly 7 is formed. Finally, multiple intermediate crossbeam assemblies 4 are welded between the right longitudinal beam assembly 6 and the left longitudinal beam assembly 7 to form a vehicle frame.

[0039] The intermediate crossbeam structure for a port tractor of the present utility model includes a longitudinal beam assembly in a box-shaped structure. At the same time, the intermediate crossbeam assembly includes two trough-shaped crossbeams, and the two trough-shaped crossbeams are connected to form a cavity-shaped structure. The use of the box-shaped structure and the cavity-shaped structure is more suitable for welding a vehicle frame, and the overall structure is simple and reliable.

[0040] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features contained in other embodiments rather than other features, the combination of features of different embodiments also means that it is within the protection scope of the present utility model and forms different embodiments. For example, in the above embodiments, those skilled in the art can use them in a combined manner according to the known technical solutions and the technical problems to be solved by this application.
