[0059] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0060] Example:

[0061] like Figure 1As shown, an embodiment of the present application discloses a front plate structure of a wide-body mining car cargo box, which adopts a separate design and can be disassembled and assembled. The specific structure includes: a brim assembly 1 and a front plate assembly 2.

[0062] like Figures 3 to 5 As shown, the brim assembly 1 includes: a brim front plate 11, a brim top plate 12, a plurality of first vertical beams 13 and a plurality of first hanging ears 14, which are arranged as follows:

[0063] The brim front plate 11 is arranged vertically and serves as the basic supporting structure of the entire assembly;

[0064] The brim top plate 12 is provided at the top of the brim front plate 11 and extends toward the front side, and is used to shield the upper end of the cab of the mining dump truck;

[0065] A plurality of first vertical beams 13 are laterally spaced and arranged on the front side of the brim front plate 11 , and the bottom end height is higher than the bottom end height of the brim front plate 11 , and preferably there are four first vertical beams, but not limited thereto.

[0066] A plurality of first hanging ears 14 are laterally spaced apart and arranged on the rear side of the brim front plate 11 and located at the bottom end of the brim front plate 11 . There are preferably three of them, but not limited thereto. No specific limitation is made thereto.

[0070] A plurality of second lifting ears 23 are laterally spaced apart and disposed on the rear side of the cargo box front plate 21 and located at the top end of the cargo box front plate 21 .

[0071] The first lifting lug 14 and the second lifting lug 23 correspond to each other one by one and are bolted together.

[0072] The installation method of the above technical solution is as follows:

[0073] like Figure 1 and Figure 2As shown, when the brim assembly 1 is installed on the front plate assembly 2, the bottom end of each first vertical beam 13 is in contact with the top end of the cross beam 22 located at the top, and at the same time, the front side surface of the brim front plate 11 is in contact with the rear side surface of the cross beam 22 located at the top, thereby forming a limit engagement, so that the first lifting ear 14 just corresponds to the second lifting ear 23, thereby quickly and conveniently completing the bolt connection between the two; in addition, it also avoids the bending stress concentration on the brim front plate 11, causing it to deform.

[0074] The brim assembly 1 of the present invention is detachable, thereby solving the problem of the vehicle being transported at an excessive height and being unable to operate in height-restricted areas, and the bolt connection of the first lifting ear 14 and the second lifting ear 23 ensures the stability of the connection and improves the portability of assembly and disassembly, and further provides a first vertical beam 13 on the front side of the brim front plate 11, and makes the top of the uppermost cross beam 22 abut against the first vertical beam 13, and the rear side fits with the brim front plate 11, thereby forming a limited engagement, thereby ensuring a compact structure while improving the structural strength of the brim, enhancing the bearing capacity of the docking area, and strengthening the impact resistance of the overall structure.

[0078] By arranging the brim channel steel 15 and the connecting plate 16, the upper part of the brim top plate 12 can be wrapped, which can prevent the materials accumulated on the top plate of the first lifting ear 14 from falling from the front end and both sides, thereby avoiding damage to the mine car and the occurrence of safety accidents caused by this, and improving the protection performance.

[0079] In some embodiments, as Figure 5 As shown, the brim assembly 1 includes: a plurality of first channel steels 17 and a plurality of groups of second channel steels 18, which are arranged as follows:

[0080] A plurality of first channel steels 17 are arranged at intervals on the lower side of the brim top plate 12, and the rear ends thereof correspond to and are fixedly connected to the first vertical beams 13 one by one;

[0081] Several groups of second channel steels 18 are arranged on the lower side of the brim top plate 12 and are spaced apart along the axial direction of the first channel steel 17, and each group of second channel steels 18 and first channel steels 17 are alternately connected laterally. They are preferably arranged as one group, but are not limited to this and are not restricted.

[0082] By forming the brim channel steel 15 and the connecting plate 16 into a horizontal and vertical alternating structure, the structural strength of the brim top plate 12 can be significantly enhanced, the load-bearing capacity is improved, and the protection effect on the cab is enhanced.

[0083] In some embodiments, as Figure 6 As shown, there are two cross beams 22 , and the front plate assembly 2 includes: a plurality of second vertical beams 24 , which are laterally spaced apart and arranged on the front side of the cargo box front plate 21 and are arranged between the two cross beams 22 .

[0085] By providing a plurality of second vertical beams 24 , two adjacent horizontal beams 22 can be connected, thereby forming a horizontal and vertical alternating structure, thereby improving the structural strength, load-bearing capacity, impact resistance and deformation resistance of the cargo box front plate 21 .

[0086] In some embodiments, as Figure 6 As shown, the front plate assembly 2 includes: a pair of first middle vertical ribs 25 and a plurality of pairs of second middle vertical ribs 26, which are arranged as follows:
