Description

Technical Field

[0001] The utility model relates to the field of dump trucks, in particular to a dump truck cargo box turnover structure and a dump truck. Background Art

[0002] Dump trucks are specially designed vehicles widely used in industries such as civil engineering, mining, agriculture, and waste disposal. They are primarily used to transport bulk materials such as sand, gravel, soil, and coal. They utilize hydraulic or mechanical lifting mechanisms to automatically unload cargo, significantly saving unloading time and labor, shortening transportation cycles, improving production efficiency, and reducing transportation costs.

[0003] The dump truck has a flippable cargo box, which is mounted on a vehicle frame via a flippable support structure. Currently, the support structure for the flipping cargo box is typically composed of two mutually hinged parts, one part connected to the cargo box and the other connected to the vehicle frame.

[0004] In the above existing structures, the flip seat is mostly installed on the outside of the frame longitudinal beam, and an additional fixed support needs to be provided on the outside of the frame. The flip seat has a complex structure, is heavy, and needs to be cast or forged, which is costly. Summary of the Invention

[0005] The utility model aims to solve the problems of the current dump truck cargo box turnover seat having a complex structure, heavy weight and high cost, and provides a dump truck cargo box turnover structure with a lighter weight and simplified structure.

[0006] To address the aforementioned issues, the present invention employs a technical solution comprising a dump truck cargo box flip structure, comprising a frame longitudinal beam and a cargo box longitudinal beam, with a flip seat disposed between the frame and cargo box longitudinal beams. The flip seat comprises a left panel and a right panel, the frame and cargo box longitudinal beams being positioned between the left and right panels. The upper portions of the left and right panels are fixedly connected to the cargo box longitudinal beams, and hinge holes are defined in the frame longitudinal beams, at which the left and right panels are hingedly mounted. This solution utilizes a panel structure to form the flip seat, with the upper portion of the panel fixedly connected to the cargo box longitudinal beams and the lower portion directly hinged to the frame longitudinal beams. This simplifies the flip seat structure and reduces manufacturing costs.

[0007] Preferably, a horizontal connecting plate is provided between the left panel and the right panel, and a set of opposite sides of the horizontal connecting plate are fixedly connected to the left panel and the right panel respectively. The flip seat is an H-shaped integrated structure, which is easy to manufacture and install and improves the overall strength.

[0008] Preferably, a vertical connecting plate is further provided between the left and right panels, with a pair of opposite sides of the vertical connecting plate being fixedly connected to the left and right panels, respectively, and one side surface of the vertical connecting plate being connected to the horizontal connecting plate. The left and right panels, the horizontal connecting plate, and the vertical connecting plate form a three-dimensional structure, further enhancing the strength of the flip seat.

[0009] Preferably, the left and right panels are both stepped and symmetrically bent, with the upper spacing between the left and right panels smaller than the lower spacing. A horizontal connecting plate connects the left and right panels at their bend. The flip seat utilizes a variable cross-section design, which not only adapts to the varying widths of the frame and cargo box rails but also enhances its overall strength.

[0010] Preferably, the lower parts of the left panel and the right panel are respectively provided with pin holes, and the pin holes are coaxially arranged with the hinge holes on the frame longitudinal beams and are jointly plugged with pins.

[0011] Preferably, one end of the pin is provided with a shoulder, the outer edge of which is provided with a cut surface along a chord, the outer side surface of the left panel and / or the right panel is provided with a shoulder block, the side surface of the shoulder block contacts the cut surface of the shoulder, the other end of the pin is provided with a cotter pin mounting hole and a cotter pin is mounted therein, and a washer is provided between the cotter pin and the flip seat. This can prevent the upper assembly from flipping over, the pin does not rotate, and relative motion occurs between the rear rotary flip seat and the pin, thereby improving positioning performance.

[0012] Preferably, a first positioning hole is provided on the upper portion of the left panel and the right panel, and a second positioning hole is provided on the longitudinal beam of the cargo box, and the first positioning hole and the second positioning hole are coaxially positioned.

[0013] Preferably, the left side panel includes a left inner panel and a left outer panel, which are bonded and fixedly connected. The right side panel includes a right inner panel and a right outer panel, which are bonded and fixedly connected. Both the left and right side panels are formed by bonding two panels together, which reduces the thickness of the panels, increases the molding effect of the panels, and improves the load-bearing performance of the rear swivel flip seat.

[0014] Preferably, a reinforcement plate is provided at a position of the cargo box longitudinal beam corresponding to the flip seat.

[0015] On the other hand, the present invention also provides a dump truck, which adopts the above-mentioned dump truck cargo box flipping structure.

[0016] The above technical solutions show that the advantages of the present invention are as follows: In the flip structure provided by this solution, the flip seat is directly mounted on the frame longitudinal beam and the cargo box longitudinal beam, eliminating the need for additional supports on the frame assembly, which can reduce costs and reduce vehicle weight. The flip seat is welded into an assembly using multiple panels, which has the advantages of easy processing and high assembly precision. Through structural design, the panels support each other, resulting in high overall strength. Positioning holes are provided on the rotating flip seat and the cargo box longitudinal beam, respectively, which can improve assembly precision and the coaxiality between the two flip seats. Furthermore, the dump truck provided by the present invention is more lightweight and has a high flip structure strength. BRIEF DESCRIPTION OF THE DRAWINGS
