Description

Technical Field

[0001] The utility model relates to the technical field of unmanned transport vehicles, in particular to a novel frame of a port unmanned transport vehicle and a port unmanned transport vehicle. Background Art

[0002] The frames of existing port unmanned transport vehicles are generally composed of two longitudinal beams and a number of crossbeams transversely arranged on the longitudinal beams. Most of the existing crossbeams adopt a segmented structure, and then the various segments are connected to the longitudinal beams by fasteners such as bolts to form a crossbeam. However, some frames abandon the segmented crossbeam structure and adopt the form of a through beam. Most of the existing through beam structures are shown in an assembled frame disclosed in the Chinese patent with publication number CN208291334U, in which the through beam passes through the longitudinal beam, and the contact part between the through beam and the longitudinal beam is recessed downward to keep the upper surfaces on both sides of the through beam flush with the upper surface of the longitudinal beam, so as to facilitate the installation of subsequent carriages. However, the structure with the recessed middle part increases the difficulty of assembling the through beam and the longitudinal beam. Utility Model Content

[0027] When implementing it, Figure 1 , Figure 2 As shown, the new type of port unmanned transport vehicle frame includes two longitudinal beams 10 and a plurality of cross beams 11 transversely arranged on the longitudinal beams 10;

[0028] The cross beam 11 includes a first cross beam 111 and a second cross beam 112 that are horizontally adjacent to each other; the first cross beam 111 and the second cross beam 112 are both arranged on one side close to the upper surface of the longitudinal beam 10;

During assembly, the first crossbeam 111 and the second crossbeam 112 can be directly passed through the two longitudinal beams 10 in sequence, respectively, so the installation is simple and convenient;

[0030] The longitudinal beam 10 is made of an I-beam with an I-shaped cross section. The I-beam has better stress resistance and higher strength than other structures. The first cross beam 111 and the second cross beam 112 are made of rectangular profiles with a rectangular cross section.
