L-shaped casting combined bracket for fixing LNG (Liquefied Natural Gas) cylinder of heavy truck

The utility model relates to the technical field of LNG (Liquefied Natural Gas) cylinder brackets, in particular to an L-shaped casting combined bracket for fixing an LNG cylinder of a heavy truck. The support comprises four upper supports, two lower supports, a right front lower support and a left front lower support. The four upper supports are fixed on the LNG cylinder frame, the lower support and the right front lower support are fixed on the right longitudinal beam, the lower support and the left front lower support are fixed on the left longitudinal beam, and the upper supports and the lower support, the lower support and the right front lower support, and the lower support and the left front lower support are connected and fastened through bolts, nuts and flat washers. The LNG cylinder fixing and welding support solves the problems that an existing LNG cylinder fixing and welding support cracks frequently, and connecting bolts of an upper support and a lower support loosen and fall off frequently.
