[0030] When using the fuel locomotive carrier clamping structure provided by the novel embodiment 1 of the present invention, several carrier assemblies are arranged in the horizontal direction and loaded into the body 1. The carrier assemblies are stably placed on the top of the bottom cover 3, and the bottom cover 3 holds up the carrier assemblies; when all the carrier assemblies are placed in the body 1, there is no gap between the carrier assemblies, and there is no gap between the carrier assemblies and the body 1, and the carrier assemblies cannot be displaced in the horizontal direction; when all the carrier assemblies are placed, the top cover 2 is arranged above the carrier assemblies, so that the top cover 2 can be detachably fixed to the top of the body 1, and the top cover 2 presses the carrier assembly on the bottom cover 3, and the carrier assembly cannot be displaced in the vertical direction; an air outlet cone is installed above the carrier clamping structure; the air outlet cone and the top of the body 1 are tightened and fixed by a number of bolts, Figures 1 to 4 The bolts vertically arranged on the top of the middle and outer frames are the bolts for fixing the outlet cone. In order to make the carrier compression structure clear, the outlet cone is not shown in the figure.
