In the illustrated embodiment of the present invention, the exhaust gas aftertreatment package 100 further includes two sets of reinforcing sheets 14 disposed at four corners of the outer casing 1, where the two sets of reinforcing sheets 14 respectively correspond to the first welding seams 131 and the second welding seams 132 of the outer casing 1. Preferably, the reinforcing sheet 14 is welded to the corresponding first weld 131 and second weld 132; due to the arrangement, on one hand, the structural strength of the four corners is improved; on the other hand, the method is favorable for preventing the welding seam from cracking. In the illustrated embodiment of the present invention, the reinforcing sheet 14 protrudes from the corresponding first outer case 11, second outer case 12, and third outer case 13. Each reinforcing plate 14 comprises two grooves 141 arranged at intervals and a weld abdicating groove 142 arranged between the grooves 141, the grooves 141 are used for positioning two ropes 751, and the weld abdicating groove 142 is used for covering the corresponding first weld 131 or second weld 132. Referring to fig. 1 and 3, since the reinforcing pieces 14 protrude from the corresponding first outer shell 11 and second outer shell 12, when two ropes 751 are installed in place, a gap 15 is formed between two circumferentially adjacent reinforcing pieces 14 and between the corresponding first outer shell 11 and second outer shell 12 of the two ropes 751, that is, the two ropes 751 do not contact the upper surface, the lower surface, the left surface and the right surface of the outer shell 1. By providing the gap 15, the friction area of the rope 751 with the outer shell 1 is reduced, thereby reducing the risk of failure of the rope 751.
The above embodiments are only for illustrating the invention and not for limiting the technical solutions described in the invention, and the understanding of the present specification should be based on the technical personnel in the field, and although the present specification has described the invention in detail with reference to the above embodiments, the technical personnel in the field should understand that the technical personnel in the field can still make modifications or equivalent substitutions to the present invention, and all the technical solutions and modifications thereof without departing from the spirit and scope of the present invention should be covered in the claims of the present invention.
