[0042] The utility model discloses a modular heating type arc carriage, whole assembly simple and convenient, can effectively reduce maintenance cost and time.

[0043] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as limiting the utility model.

[0044] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise explicitly specified.

[0045] Reference is made below Figures 1 to 12 The modular heating type arc carriage in the embodiments of the utility model is described.

[0046] A modular heating type arc carriage is disclosed in the embodiments of the application, and the whole carriage adopts modular design, which comprises: a carriage module one 1, a carriage module two 2, a carriage module three 3, a carriage module four 4, a carriage module five 5, a carriage module six 6 and a carriage module seven 7, and the modules are connected by bolts.

[0047] By dividing the whole carriage of the mine dump truck into seven modules, on the one hand, the manufacturing difficulty of the whole carriage can be reduced, and on the other hand, the transportation difficulty of the carriage is significantly reduced, especially for the carriage of a large-tonnage mine dump truck, the overall width of the carriage exceeds the transportation limit, so it cannot be welded and transported as a whole, and needs to be transported to the construction site in two parts for on-site welding, which significantly improves the manufacturing and transportation difficulty. The carriage in the embodiments is divided into small volume and small weight carriage modules by modular design, which not only facilitates manufacturing, but also facilitates transportation.

[0048] Meanwhile, the on-site welded carriage is limited by the site environment, the welding technology of workers and other aspects, the welding quality of the carriage is uneven, and the overall quality of the carriage cannot be guaranteed. The carriage modules in the embodiment are connected by bolts, which avoids the problem that the welding quality cannot be guaranteed due to the welding technology, makes the assembly of the overall carriage more convenient and fast, and effectively saves the assembly time. In addition, the traditional carriage is integrally welded, and once a part of the carriage is damaged, the overall carriage needs to be replaced, which undoubtedly greatly increases the maintenance cost and maintenance time. The modularized carriage in the embodiment only needs to replace the corresponding module when a part is damaged, which not only reduces the maintenance cost, but also effectively shortens the maintenance time.

[0049] In some embodiments, for example Figure 6 As shown in the figure, the carriage module one 1 includes a protective plate front part 11, which is designed in an overall arc structure, and a plurality of triangular reinforcing structures 111 are arranged in the middle part. The arc structure design and the triangular reinforcing structures 111 can effectively improve the structural strength of the overall protective plate, so that the protective plate can provide stronger protection performance.

[0050] Further, the carriage module one 1 further includes a rearview mirror protection assembly 12, which is arranged on the left and right sides of the protective plate front part 11. The rearview mirror protection assembly 12 includes a support bent plate 121 and a reinforcing rib plate 122, and the support bent plate 121 is tightly fastened with the reinforcing rib plate 122. The rearview mirror protection assembly 12 can provide sufficient protection for the rearview mirror, and the reinforcing rib plate 122 effectively improves the structural strength of the overall rearview mirror protection assembly 12.

[0051] In some embodiments, for example Figure 7 As shown in the figure, the carriage module two 2 includes a protective plate rear part 21 and a front plate upper part 22, which are welded and fixed between each other. The protective plate rear part 21 and the front plate upper part 22 are designed in an arc structure, which can effectively improve the structural strength of the overall protective plate and front plate, and can also improve the carrying capacity and stability of the overall carriage. The protective plate rear part 21 is connected with the protective plate front part 11 by bolts to form the overall protective plate. The triangular reinforcing structures 111 on the protective plate front part 11 extend to the entire protective plate to strengthen the overall protective plate. The plate thickness of the protective plate rear part 21 is greater than that of the protective plate front part 11. For example, the protective plate rear part 21 is made of a high-strength alloy steel plate with a plate thickness of 10 mm, and the protective plate front part 11 is made of a high-strength alloy steel plate with a plate thickness of 8 mm. The plate thickness and material of the protective plate rear part 21 and the protective plate front part 11 can be adjusted according to actual needs, which is not limited here.

[0052] Further, since the connecting part between the rear part 21 of the protection plate and the upper part 22 of the front plate is a right-angle bend, the welding seam of the connecting part is subjected to greater stress and is prone to deformation cracking. In the embodiment, a reinforcing bent plate 23 is welded and fixed to the connecting part between the rear part 21 of the protection plate and the upper part 22 of the front plate, which can effectively compensate the structural strength of the connecting part and prevent the welding seam of the connecting part from cracking.

[0053] Further, the left and right sides of the second carriage module 2 are respectively provided with a left side plate 24 and a right side plate 25, the left end faces of the rear part 21 of the protection plate and the upper part 22 of the front plate are both welded and fixed to the left side plate 24, the right end faces of the rear part 21 of the protection plate and the upper part 22 of the front plate are both welded and fixed to the right side plate 25, and a plurality of triangular reinforcing ribs 26 are arranged between the upper part 22 of the front plate and the left and right side plates 24 and 25. The arrangement of the left and right side plates 24 and 25 can effectively improve the protection of the front cab and prevent the goods from impacting the side of the cab, and the arrangement of the triangular reinforcing ribs 26 can compensate the connecting strength of the side plates and the two ends of the second carriage module 2 and avoid the welding seam of the connecting part from cracking.

[0054] In addition, the connecting parts of the two ends of the upper part 22 of the front plate and the side plates adopt a circular arc transition, which can improve the sticking problem of the carriage.

[0058] When the temperature is low in winter, the problem of sticking material is prone to occur in the front part of the carriage. The embodiment is arranged with the first cross beam 311, the first longitudinal beam 312 and the second cross beam 321 with heating channels in the front part of the carriage to heat the front part of the carriage to solve the problem of sticking material in the front part of the carriage. The specific heating process is that the high-temperature gas discharged in the power exhaust duct enters the second cross beam 321 through the smoke hole 3211, and continues to enter the first longitudinal beam 312 and the second cross beam 321 along the heating channel, and finally is discharged from the smoke hole 3211 on the second cross beam 321.
