At the same time, the muffler of the mining vehicle is generally arranged on the left or right side of the frame. The exhaust pipe from the engine to the muffler needs to occupy the space between the rear side of the cab and the cargo box. In addition, due to its high temperature, in order to avoid safety hazards, the CNG cylinder needs to be separated from it by more than 250mm for heat dissipation. Therefore, according to the traditional bracket, a larger space will be required for the installation of the CNG cylinder, which will greatly lengthen the wheelbase, which is not conducive to the layout and load distribution of the entire vehicle.

[0005] Furthermore, the gas cylinder mounting frame is composed of columns, longitudinal beams, cross beams, and reinforcing support rods; the columns, longitudinal beams, cross beams, and reinforcing support rods are each provided with a plurality of mounting holes; the columns are respectively fixedly connected to the longitudinal beams, cross beams, and reinforcing support rods through the mounting holes.

[0006] Furthermore, the gas cylinder mounting bracket assembly consists of a lower mounting left bracket, a lower mounting right bracket, a mounting bracket, and an upper mounting fixed bracket; multiple mounting brackets are arranged on the lower mounting left bracket and the lower mounting right bracket, and an upper mounting fixed bracket is arranged on the mounting bracket; the mounting bracket is fixedly connected to the gas cylinder mounting frame through mounting hole mounting bolts; and the gas cylinder is placed on the mounting bracket.

[0007] Furthermore, a rubber band is provided at the semicircular arc of the mounting bracket where the gas cylinder is placed.

[0008] Furthermore, there are 7 gas cylinders.

[0009] Beneficial effects of the utility model:

[0010] 1. Reserve space for the installation and heat dissipation of the exhaust pipe, so that the wheelbase can be shortened by 200-300mm while ensuring the cruising range, ensuring the load distribution of the cargo box; 2. Adopt an assembled frame installation structure to facilitate shipment and installation and disassembly; 3. The structure is easy to install, has high structural strength and a longer cruising range.
