[0026] Please refer to Figure 1 and Figure 2, the lifting seat beam of the wide-body vehicle frame provided by the present utility model will be described. The lifting seat beam of the wide-body vehicle frame includes: a lifting seat beam main body and two groups of vehicle frame mounting supports. The lifting seat beam main body includes two parallel channel steels and an upper flat plate 9 connected to the openings of the two channel steels. After the upper flat plate 9 is connected to the two channel steels, two box-shaped structures are formed; the two groups of vehicle frame mounting supports are symmetrically fixed to the bottoms of the two channel steels along the center line of the length of the channel steels, and the two groups of vehicle frame mounting supports are fixed to the vehicle frame together.

[0027] For the lifting seat beam of the wide-body vehicle frame provided by the present utility model, the lifting seat beam main body adopts two parallel channel steels, and the upper flat plate 9 is used to fix the two parallel channel steels together, forming two box-shaped structures, which can improve the overall bending and torsion load resistance and impact load resistance of the lifting seat beam, prevent the risk of structural fracture, and improve the operation reliability of the whole vehicle.

[0028] In this application, two channel steels are arranged in parallel to form the main body of the lifting seat beam. The upper part is connected into one body by the upper flat plate 9, and the bottom part is connected into one body by two groups of vehicle frame mounting supports. The structure is simple and easy to manufacture; this application makes use of the characteristic that the integral structural strength of the channel steel is high, and the channel steel is used as the main structure of the lifting seat beam, avoiding the risks of fracture after long-term use caused by welding, riveting and bolt connection; at the same time, the main body of the lifting seat beam in this application adopts the structural form of two channel steels, providing more spacious space for the battery layout and the overall vehicle layout in the design stage of new energy wide-body vehicles.

[0029] Regarding the specifications of the two channel steels, the same specifications can be selected, and the two channel steels have the same width and length; different specifications can also be selected, and the widths of the two channel steels are different. As shown in this application Figures 1 to 3 , for the convenience of distinction, the channel steel with a larger width is defined as the large channel steel 8, and the channel steel with a smaller width is defined as the small channel steel 14. At the same time, when different specifications of channel steels are adopted, the sizes of the channel steel side wall reinforcement plates 10 and the channel steel inner reinforcement plates 13 arranged therein are adjusted appropriately.

[0030] In some embodiments, please refer to Figure 1As shown, the frame mounting support includes a large lifting lower support flat plate 1, a small lifting lower support flat plate 2, a lifting lower support vertical plate 3, and a lifting lower support bending plate 6; the large lifting lower support flat plate 1 is fixed to the bottom of the grooves of two channel steels; the lifting lower support vertical plate 3 is vertically fixed to the large lifting lower support flat plate 1; the small lifting lower support flat plate 2 is vertically fixed to the lifting lower support vertical plate 3 and is parallel to the large lifting lower support flat plate 1; the lifting lower support bending plate 6 is connected to the large lifting lower support flat plate 1, the small lifting lower support flat plate 2, and the lifting lower support vertical plate 3 to form a box structure. Since the frame mounting support needs to be fixed to the frame, therefore, at the fixed position of the two, there needs to be sufficient stiffness and it is not easy to have the risk of fracture to ensure the reliability of the support; in order to improve the reliability of the connection position between the two in this application, the lifting lower support bending plate 6 is connected to the large lifting lower support flat plate 1, the small lifting lower support flat plate 2, and the lifting lower support vertical plate 3 to form a box structure, which has good ability to withstand bending and torsion loads and impact loads, and the contact surface between the lifting lower support vertical plate 3 and the frame is on the side and has a large contact plane, and is fixed to the frame by bolts, which can avoid the problem of poor contact between the lifting seat beam and the upper wing surface of the frame, so as to ensure that the force borne by the lifting seat beam is evenly transmitted to the frame.

[0031] In this application, the large lifting lower support flat plate 1 is fixed to the bottom of the groove of the channel steel by bolts, as Figure 4 and Figure 5 shown, a number of long circular holes 101 are provided on the large lifting lower support flat plate 1 to facilitate adjusting the assembly error when installing the large lifting lower support flat plate 1 and the channel steel and ensure the smooth assembly of the two; for the connection between other components, such as between the lifting lower support bending plate 6, the large lifting lower support flat plate 1, the small lifting lower support flat plate 2, and the lifting lower support vertical plate 3, welding connection is used.

[0032] In some embodiments, please refer to Figure 1 shown, the frame mounting support further includes a reinforcing plate structure fixed between the large lifting lower support flat plate 1 and the lifting lower support vertical plate 3; the reinforcing plate structure includes a lifting lower support triangular rib plate 5 and a lifting lower support bending rib plate 4. Among them, the lifting lower support triangular rib plate 5 is arranged in the middle of the lifting lower support vertical plate 3, and the lifting lower support bending rib plates 4 are arranged on both sides of the lifting lower support vertical plate 3; vice versa, or all are the lifting lower support triangular rib plates 5 or all are the lifting lower support bending rib plates 4, the purpose is to improve the reliability of the connection between the frame mounting support and the frame and the main body of the lifting seat beam, improve the bending and torsion resistance and impact resistance, and avoid fracture at the connection part.

[0033] Further, a plurality of lift lower support triangular rib plates 5 that are parallel and spaced apart are provided between the large flat plate 1 of the lift lower support and the vertical plate 3 of the lift lower support; or a plurality of lift lower support triangular rib plates 5 and lift lower support bent rib plates 4 that are parallel and spaced apart are provided between the large flat plate 1 of the lift lower support and the vertical plate 3 of the lift lower support, and the lift lower support triangular rib plates 5 and the lift lower support bent rib plates 4 are alternately distributed; or, lift lower support bent rib plates 4 are provided at both ends of the vertical plate 3 of the lift lower support, and lift lower support triangular rib plates 5 are provided in the middle of the vertical plate 3 of the lift lower support.

[0034] In some embodiments, please refer to Figure 1 As shown, the frame mounting support further includes a lift lower support small rib plate 7 fixed between the large flat plate 1 of the lift lower support and the lift lower support bent plate 6, aiming to improve the reliability of the connection between the frame mounting support and the frame and the main body of the lift seat beam, improve the bending and torsion resistance and impact resistance, and avoid fracture at the connection part.

[0035] Specifically, a plurality of lift lower support small rib plates 7 that are parallel and spaced apart are welded between the large flat plate 1 of the lift lower support and the lift lower support bent plate 6. The shape of the lift lower support small rib plate 7 is triangular, and the external dimension of the lift lower support small rib plate 7 is smaller than the external dimension of the lift lower support triangular rib plate 5.

[0036] The lift lower support small rib plate 7, the lift lower support triangular rib plate 5, and the lift lower support bent rib plate 4 are respectively welded to the corresponding components; for example, the two triangular sides of the lift lower support triangular rib plate 5 are respectively welded to the large flat plate 1 of the lift lower support and the vertical plate 3 of the lift lower support.

[0037] In some embodiments, please refer to Figure 3 As shown, a plurality of channel steel inner strengthening plates 13 are provided at intervals along the length direction of the channel steel. The channel steel inner strengthening plates 13 welded in the channel steel and the channel steel side wall strengthening plates 10 welded to the side wall of the channel steel can well share the impact force received during lifting, prevent the channel steel from tearing, and improve the reliability of the lifting work.

[0038] In some embodiments, please refer to Figure 2 As shown, a lift cylinder strengthening flat plate 11 is provided in the lift cylinder installation area of the channel steel, and the lift cylinder strengthening flat plate 11 fits against the bottom of the channel steel groove. The lift cylinder installation area is in the middle area of the channel steel length direction. The lift cylinder installation area is a direct stress point. Through the lift cylinder strengthening flat plate 11, the impact resistance and anti-deformation performance of the stress point can be improved, thereby providing a reliable support for the lifting work.

[0039] Optionally, the lift cylinder strengthening flat plate 11 is welded, bolted or riveted to the bottom of the channel steel groove.

[0040] In some embodiments, please refer toFigure 2 As shown, two lifting cylinder reinforcing vertical plates 12 are also provided in the lifting cylinder installation area of the channel steel. The two lifting cylinder reinforcing vertical plates 12 are symmetrically arranged on the left and right sides of the lifting cylinder installation area. The lifting cylinder reinforcing vertical plates 12 are perpendicular to the length direction of the channel steel and are welded to the two inner walls of the channel steel, further enhancing the anti-deformation ability of the lifting cylinder installation area. At the same time, since the middle of the main body length direction of the lifting seat beam is the lifting cylinder installation area, the upper flat plate 9 is symmetrically arranged on the left and right sides of the lifting cylinder installation area.

[0041] In some embodiments, please refer to Figure 2 As shown, a channel steel side wall reinforcing plate 10 is also provided on the inner side of the channel steel and near the lifting cylinder installation area.

[0042] It should be noted that in this application, when different specifications of channel steel are selected, the lifting cylinder installation area is arranged in the large channel steel 8. Similarly, in the lifting cylinder installation area of the large channel steel 8, the two side walls of the large channel steel 8 protrude upward by a certain height. At this time, the channel steel side wall reinforcing plate 10 arranged outside the lifting cylinder reinforcing vertical plate 12 is bent and extended to the protruding part to strengthen the structural strength of the corner part formed by the large channel steel 8; and the channel steel side wall reinforcing plate 10 arranged on the inner side wall of the small channel steel 14 can be a long strip plate extending along the length direction of the small channel steel 14.

[0043] And since the large flat plate is also close to the lifting cylinder installation area, in order to facilitate the installation and observation of the various reinforcing structures inside the channel steel, long holes are provided on the large flat plate.

[0044] In some embodiments, please refer to Figure 2 As shown, the channel steel side wall reinforcing plate is located outside the lifting cylinder reinforcing vertical plate 12.

[0045] Please refer to Figure 2 As shown, in this application, a lifting cylinder reinforcing flat plate 11 is provided in the lifting cylinder installation area, lifting cylinder reinforcing vertical plates 12 are provided around the lifting cylinder installation area, and a channel steel side wall reinforcing plate 10 is also provided outside the lifting cylinder reinforcing vertical plates 12, enhancing the anti-deformation ability of the force-bearing area of the lifting cylinder, preventing the risk of structural deformation caused by excessive impact force during lifting. Therefore, strengthening treatment is carried out in the stress concentration area to ensure the reliability of the vehicle's lifting work.

[0046] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0047] Based on the same inventive concept, the embodiments of this application also provide a wide-body dump truck, including the lifting seat beam of the wide-body vehicle frame described above.
