Description

Technical Field

[0001] This utility model relates to a sub-beam structure for an aerial work platform vehicle, belonging to the field of aerial work platform vehicles. Background Technology

[0002] With social development and technological progress, the application fields of aerial work platforms are constantly expanding, including aerospace, shipbuilding, petroleum, wind power generation, highway and elevated bridge maintenance, high-rise building facade maintenance, traffic lights, urban surveillance, and outdoor advertising. Aerial work platforms also come in various forms, such as folding, straight-reaching, and hybrid types. Depending on the application scenario, aerial work platforms are further divided into standard and insulated types.

[0003] To adapt to market changes and user preferences, the aerial work platform vehicle industry has developed rapidly. Currently, to meet users' demands for blue license plates on these vehicles, higher requirements are placed on lightweight structures. Existing technologies for aerial work platform vehicle subframe structures include... Figure 1-3 As shown, its main sub-beam 3 is usually composed of a rectangular box structure consisting of a left side plate 11, an upper side plate 12, a lower side plate 13, and a right side plate 14. A web plate 15 is provided inside the rectangular box. The above structure results in the main sub-beam structure of the aerial work platform vehicle accounting for a large proportion of the vehicle's weight. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a sub-beam structure for an aerial work platform with a reasonable structural design.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: the sub-beam structure of the aerial work platform includes a column, a crossbeam, a sub-beam body, a front fixed outrigger frame, and a rear fixed outrigger frame. The column, crossbeam, front fixed outrigger frame, and rear fixed outrigger frame are all installed on the sub-beam body. Its structural feature is that the sub-beam body includes a left longitudinal beam and a right longitudinal beam. The left and right ends of the crossbeam are respectively connected to the left and right longitudinal beams. The left longitudinal beam includes a lower side plate and an upper side plate, and the lower side plate is connected to the upper side plate. The right longitudinal beam includes a lower side plate and an upper side plate, and the lower side plate is connected to the upper side plate.

[0006] Furthermore, the front fixed leg frame includes a right front fixed leg frame and a left front fixed leg frame.

[0007] Furthermore, the lower side plate of the left longitudinal beam, the upper side plate of the left longitudinal beam, the lower side plate of the right longitudinal beam, and the upper side plate of the right longitudinal beam are all arranged in an L-shape.

[0008] Furthermore, the crossbeam, left longitudinal beam, and right longitudinal beam are all designed with a frame structure.

[0009] Compared with the prior art, this utility model has the following advantages: while ensuring the strength and rigidity of the sub-beam structure, the main body of the sub-beam is changed to two longitudinal beams (left longitudinal beam and right longitudinal beam), and the two longitudinal beams are connected by a crossbeam. The crossbeam, left longitudinal beam and right longitudinal beam are set into a rectangular box structure, which can significantly reduce the weight of materials and better achieve structural lightweighting.

[0018] Example.

[0019] See Figures 4 to 6As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention.
