[0002] The existing off-road dump truck cargo box bottom beam and frame are separate structures, and the cargo box bottom beam is only connected by a rotating shaft and does not participate in the frame structure support. When the uneven road conditions in mining areas cannot be guaranteed, the cargo box is prone to pendulum motion under heavy load conditions, resulting in torsional deformation of the cargo box and frame, and severe cracks, which greatly affect the stability and body safety. The cargo box is relatively stable when it produces extension and tension movements under current working conditions due to the stable beam structure at the bottom, but it has not fully utilized the auxiliary support of the frame. Utility Model Content

[0003] The purpose of the utility model is to provide a sinking cargo box to solve the problem proposed in the above-mentioned background technology that the cargo box bottom beam does not participate in the frame structure support, and the frame is prone to torsion deformation or cracking when the road condition cannot be guaranteed, affecting the stability and safety of the vehicle body.

[0005] Among them, the cargo box beam is composed of a crossbeam and a longitudinal beam hinged on the frame to form an M-shaped structure, and the two groups of crossbeams are respectively wrapped on the outer side frames of the frame, and the tensioning limit structure is installed on the crossbeam away from the hinged frame and the tensioning ends are limited on the inner side frames of the frame.

[0006] Preferably, the tensioning limiting structure is provided with two groups of tensioning beams and connecting plates that provide the two groups of tensioning beams with linear sliding motion. The two groups of tensioning beams are fixed on the crossbeams through the connecting plates. Mounting positions for installing springs are reserved on the opposite surfaces of the two groups of tensioning beams. The elastic potential energy of the springs drives the two groups of tensioning beams to apply tensioning force outward.

[0007] Preferably, any one of the tensioning beams is provided with a side cover connected to the tensioning beam by bolts, a telescopic top rod is installed in the tensioning beam, and an extending rod of the telescopic top rod passes through the side cover and the spring and is connected to the other tensioning beam by bolts.

[0010] Preferably, both groups of tension beams are provided with rounded corners.

[0011] Preferably, the top of the protrusion is rounded.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model comprises an M-shaped structure composed of a crossbeam and a longitudinal beam, which is wrapped on the frame to realize the function of auxiliary support when the cargo box body carries heavy objects. At the same time, the hinge cooperates with the tensioning limit structure so that the front and rear cargo box beams become a whole when the cargo box produces a pendulum motion under heavy load.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 5 , a sinking cargo box, such as Figure 1As shown, it is composed of a cargo box body 1, a cargo box beam connected to the bottom of the cargo box body 1, a tensioning and limiting structure 5 installed on the cargo box beam, and a frame 2.

[0022] In specific implementation, combined with Figure 1 and Figure 2 As shown, the cargo box beam is composed of a crossbeam 3 and a longitudinal beam 4 hinged on the frame 2 to form an M-shaped structure. The two sets of longitudinal beams 4 are respectively wrapped on the outer side frames of the frame 2. The tensioning limit structure 5 is installed on the crossbeam 3 away from the hinged frame 2 and the tensioning ends are limited on the inner side frames of the frame 2.

[0023] Combination Figure 3 and Figure 4 As shown, the tensioning and limiting structure 5 is provided with two groups of tensioning beams 6 and connecting plates 7 that provide the two groups of tensioning beams 6 with linear sliding motion. The two groups of tensioning beams 6 are fixed to the crossbeam 3 through the connecting plates 7. The connecting plates 7 and the crossbeam 3 are fixed with bolts or welding, but are not limited to the above fixing methods. Those skilled in the art can make appropriate selections according to actual needs.

[0024] The two sets of tension beams 6 have mounting positions for installing springs 8 on the opposite surfaces. The elastic potential energy of the springs 8 drives the two sets of tension beams 6 to apply tensioning force outward. In this embodiment, two sets of springs 8 are symmetrically arranged between the two sets of tension beams 6. A side cover 9 connected to the tension beam 6 by bolts is arranged on any tension beam 6 to facilitate the installation of the telescopic push rod 10 and to limit the position of the telescopic push rod 10 and to install the spring 8. The telescopic push rod 10 is installed in the tension beam 6. The extension rod of the telescopic push rod 10 passes through the side cover 9 and the spring 8 and is connected to the other tension beam 6 by bolts. The two sets of tension beams 6 are locked by the extension of the telescopic push rod 10, and it also facilitates the anti-stuck when the dump truck cargo box is reset.

[0025] like Figure 5 As shown, the frame 2 is provided with a convex block 11 with a rounded top for limiting at the tension beam 6, and the convex blocks 11 are symmetrically arranged. The tension beam 6 is provided with a matching recess 12 at the convex block 11 to increase the vertical limiting stress under the tightening condition. Both sets of tension beams 6 are provided with rounded corners 13 below the recess 12 to facilitate the resetting of the dump truck cargo box.

[0026] It should be noted that: in actual use, the sinking cargo box is composed of a crossbeam 3 and a longitudinal beam 4 hinged on the frame 2 to form an M-shaped structure wrapped on the frame 2 to support the cargo box body 1 to carry heavy objects, and provide auxiliary support for the shelf. At the same time, the tensioning limit structure 5 on the crossbeam 3 is tensioned to cooperate with the hinge at the other end, so that the cargo box produces a pendulum motion under heavy load conditions, resulting in torsional deformation and cracking. At the same time, the frame 2 is provided with a protrusion 11 at the tensioning beam 6 of the tensioning limit structure 5. When in tensioning condition, the protrusion 11 is located in the depression 12 of the tensioning beam 6 to increase stress.

[0027] When the cargo box body 1 needs to be unloaded, the telescopic top rod 10 is loosened, and the cargo box body 1 is driven by the external hydraulic system to flip over and unload around the hinge between the cross beam 3 and the frame 2. Since the top of the protrusion 11 is rounded, under the influence of external force, the spring 8 between the two sets of tensioning plates 6 is compressed, and the tensioning beam 6 slides on the connecting plate 7, so that the depression 12 on the tensioning beam 6 is separated from the protrusion 11. Since the spring 8 is in a compressed state when the depression 12 is located at the protrusion 11, the elastic potential energy of the spring 8 is released after the tensioning beam 6 completely leaves the frame 2, causing the tensioning beam 6 to slide outward.

[0028] When the cargo box body 1 is reset, the rounded corner 13 at the bottom of the tensioning beam 6 first contacts the frame 2, and under the influence of the rounded corner 13 structure, the spring 8 is compressed until the depression 12 of the tensioning beam 6 is located on the protrusion 11, and the loose telescopic top rod 10 is extended until it reaches a preset pressure threshold and stops extending. The specific value of the pressure threshold needs to be set and selected by technical personnel in this field according to the material and the size of the dump truck, which will not be described in detail here.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
