All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
It should be noted that, in the description of the present utility model, terms such as "upper," "lower," "front," "rear," "left," "right," and the like indicate directions or positional relationships, and are merely used for convenience of description, but do not indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and the like, are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
Referring to fig. 1-2, the utility model discloses a three-bridge flexible mining dump truck frame (hereinafter referred to as a truck frame), which comprises a left longitudinal beam 1, a right longitudinal beam 2, a left hydro-pneumatic suspension bracket 3, a right hydro-pneumatic suspension bracket 4, a first lower connecting beam 5 and a second connecting beam 6.
The left hydro-pneumatic suspension bracket 3 and the right hydro-pneumatic suspension bracket 4 are matched with the first lower connecting beam 5 for installing a front axle besides being used for installing hydro-pneumatic spring suspensions. The second connecting beam 6 is used for mounting the center and rear axles. The left hydro-pneumatic suspension bracket 3 and the right hydro-pneumatic suspension bracket 4 are bolted (by bolting) on the outer side of the left side member 1 and the outer side of the right side member 2, respectively. The two ends of the first lower connecting beam 5 are respectively bolted to the bottom of the left hydro-pneumatic suspension bracket 3 and the bottom of the right hydro-pneumatic suspension bracket 4. The second connecting beam 6 is riveted at both ends to the left side member 1 and the right side member 2, respectively.
In the present utility model, the left hydro-pneumatic suspension bracket 3, the right hydro-pneumatic suspension bracket 4 and the first lower connecting beam 5 for mounting the front axle are connected with the left side frame 1 and the right side frame 2 by bolting, and the second connecting beam 6 for mounting the middle axle and the rear axle is connected with the left side frame 1 and the right side frame 2 by riveting. The riveting and bolting have lower requirements on the construction process, so that the manufacturing and processing difficulty is reduced, meanwhile, the riveting and bolting can realize smooth and flexible force transmission, and the abrupt change of rigidity is avoided, so that the reliability of the frame is improved.
The U-shaped plate is formed by bending and flanging a flat plate and comprises a web plate and two side plates. The U-shaped plate has higher structural strength than the flat plate. However, if the thickness of the flat plate is thicker, the two side plates formed by bending are gradually opened in the direction away from the web plate, so that the outer contour size of the U-shaped plate does not reach the standard. If the thickness of the plate is thin, the structural strength of the plate is affected. In order to achieve the thickness and the U-shaped structure, the left longitudinal beam 1 is designed into a double-layer U-shaped plate, and the thickness of each U-shaped plate in the double-layer U-shaped plate is thinner, so that the U-shaped structure with regular bending and forming is facilitated. The double-layer U-shaped plate has a thicker thickness because of the superposition of the two U-shaped plates.
Specifically, the left side member 1 of the present utility model includes a web 101, and an upper side plate 102 and a lower side plate 103 provided separately on the upper and lower sides of the web 101, and the left side member 1 is formed by nesting a left outer side member and a left inner side member with each other to form a double-layered structure.

The right side member 2 includes a web 201, and an upper side plate 202 and a lower side plate 203 provided on upper and lower sides of the web 201.
In a specific embodiment of the utility model, the single-layer U-shaped plates in the left longitudinal beam 1 and the right longitudinal beam 2 are formed by bending 610L of plates, the thickness of the 610L of plates is 6mm, and the thickness of double-layer webs of the left longitudinal beam 1 and the right longitudinal beam 2 after forming is 12mm.

The upper right connecting plate 8 and the lower right connecting plate 9 have similar beneficial effects to the upper left connecting plate 7, and are not described in detail herein.
The second connecting beam 6 specifically includes a front beam plate 61 and a rear beam plate 62. The front beam plate 61 and the back beam plate 62 are all U-shaped plates, the opening of the front beam plate 61 faces forward, and the opening of the back beam plate 62 faces backward, namely two back-to-back arranged U-shaped plates. The front beam plate 61 includes a web and upper and lower side plates provided on upper and lower sides of the web.

In the specific embodiment of the utility model, a first upper connecting beam 10 is further arranged, and two ends of the first upper connecting beam 10 are respectively bolted with the top of the left hydro-pneumatic suspension bracket 3 and the top of the right hydro-pneumatic suspension bracket 4, so that the overall stability of the frame is improved.
In order to ensure the stability of the operation of the motor, the utility model arranges a left reinforcing connecting bracket 11, a right reinforcing connecting bracket and a third connecting beam 12 on the left longitudinal beam 1 and the right longitudinal beam 2 corresponding to the region of the motor.

So set up, strengthened the position that is used for supporting the motor on left longeron 1 and right longeron 2 to ensure the stable work of motor.
The distance between the third connecting beam 12 and the second connecting beam 6 is large, and if no reinforcement is taken, the strength of the portion of the frame between the third connecting beam 12 and the second connecting beam 6 is weak while the uniform dispersion of the forces on the frame is not favored. Thus, the present utility model provides two fourth connecting beams 13 between the third connecting beam 12 and the second connecting beam 6. The two fourth connecting beams 13 are arranged at intervals. Both ends of the fourth connecting beam 13 are respectively riveted to the left side member 1 and the right side member 2.
