Problems solved by technology
[0005] Rear-mounted gas cylinders In view of the high center of gravity after the gas cylinders are stacked, the gas cylinder bracket must have strong impact resistance. Therefore, the manufacturer has to use a welded reinforced bracket. This bracket takes up a lot of space on the frame, resulting in The size of the cargo box is shortened, and the carrying capacity is significantly reduced compared with the coaxial long diesel truck, and the gas cylinders have to be inserted into the frame one by one, and then hoisted as a whole, which makes the installation complicated; at the same time, due to the existence of the bracket, the dump truck side The beam cannot be extended forward, and the bodybuilder must either shorten the length of the sub-frame on the premise of affecting the overall strength of the frame, or hoist the rear gas cylinder device as a whole, install the sub-frame and then hoist it to the sub-frame. very cumbersome

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Such as Figure 1-Figure 4 As shown, a CNG dump truck gas cylinder modular arrangement system includes a rear gas cylinder device 4 and a side gas cylinder device 5 arranged on the vehicle frame 1 and the grooved beam 2 of the dump truck chassis. A backing plate 3 is provided between the gas cylinder device 4 and the channel beam 2 .
[0024] The rear gas cylinder device 4 includes front, middle and rear three rows of brackets 7, and the brackets 7 are connected by upper, middle and lower three layers of gas cylinder brackets 8. The front and rear exhaust bottles 9 are divided into upper, middle and lower layers and fixed on the gas bottle bracket 8 by means of fasteners. The brackets 7 are all truss structures formed by steel pipes interlocking and welded together, wherein the steel pipes arranged horizontally in the rear row of brackets 7 are...

The invention discloses a modular distribution system of gas cylinders on a CNG (compressed natural gas) dump track, comprising a frame, a rear gas cylinder device and a side gas cylinder device, wherein the frame is arranged on a chassis of the dump track; the rear gas cylinder device and the side gas cylinder device are arranged on groove-shaped beams; cushion plates are arranged between the rear gas cylinder device and the groove-shaped beams. The rear gas cylinder device leaves the distribution space for a lifting cylinder of the dump track by combination of the gas cylinders and the bending of a bracket, so that the space of a container of the dump track is furthest increased on the premise of ensuring the driving range, simultaneously the installation procedure of the gas cylinders and the gas cylinder bracket is simplified, and the labor intensity of workers is greatly reduced; and the side gas cylinder device is fixed on an auxiliary frame and a longitudinal beam by bolts, so that the space is fully utilized, the gap of the gas cylinder from the ground is enlarged, and the passability of vehicles is improved. The system has the advantages of compact structure, convenience in installation, strong impact resistance, firmness and reliability.
Description
[0001] technical field [0002] The invention relates to the technical field of dump truck fuel supply, in particular to a dump truck gas cylinder arrangement system using CNG as natural gas engine fuel. Background technique [0003] At present, with the soaring fuel prices and the implementation of my country's new energy development strategy, energy conservation and emission reduction and low-carbon economy have gradually become distinct growth themes. Vehicles using natural gas as an alternative fuel are increasingly occupying the Chinese market. Although CNG ( Compressed natural gas) as a fuel vehicle is environmentally friendly, economical and has good low-temperature starting performance, but currently it is mostly concentrated on tractor models. In the field of dump trucks, due to the influence of the layout space of CNG gas cylinders, automobile manufacturers often adopt the form of side-mounted gas cylinders, and some manufacturers adopt the form of rear-mounted and ...
