Gas cylinder fixing rack, gas cylinder frame, LNG gas supply system and vehicle

Abstract

The invention provides a gas cylinder fixing rack, a gas cylinder frame, an LNG gas supply system adopting the frame, and a vehicle. The gas cylinder frame comprises an external fixing connection portion, an internal holding portion and a supporting connection part arranged between the external fixing connection portion and the internal holding portion, the fixing connection portion is fixedly connected with a vehicle body or other parts, the holding portion internally holds and fixes a gas cylinder, the supporting connection part is connected to the fixing connection portion and the holding portion, the fixing frame is evenly divided into at least two modularized mounting racks, and the modularized mounting racks have a same shape. Batch production and rapid connecting use are realized, so the cost is saved, and the precision and the quality stability of the frame are improved.

Description

technical field [0001] The invention relates to gas cylinder fixing technology, in particular to a gas cylinder frame, an LNG gas supply system and a vehicle using the same. Background technique [0002] Vehicles that use LNG as fuel, especially the rear double-layer gas supply system of heavy trucks, because the shape of the cylinder body is generally cylindrical or elliptical, which has no stable support for its own shape, so the existing gas cylinders The fixed frame generally includes an external fixed connection part, an internal fastening part and a supporting connection part between the two. The fixed connection part is used for fixed connection with the body or other parts, and the fastening part is used for fixing the gas cylinder inside, and the support connection Parts are used to connect the fixed connection part and the holding part. The whole system is a cuboid structure, the upper and lower gas cylinders are installed in the cuboid frame, and the traditional ...

AI Technical Summary

Problems solved by technology

Although it can meet the requirements of installing gas cylinders, the frame of this structure is composed of a large number of section steels, which has a large dead weight. When the frame and gas cylinders are full, the total weight is more than 1 ton, which is difficult to meet the requirements of lightweight heavy trucks

[0004] For example, the device disclosed in the Chinese patent application No. 201320156366.9 utility model patent, the upper and lower gas cylinder structures are installed in a square frame, the assembly of the system must be carried out in the frame, the connection of the upper and lower pipelines takes a long time and is difficult Large, at the same time, the connection between the upper and lower bottles cannot be quickly disassembled

[0005] There is such a problem in the use of this device: the frame is spliced ​​by many section steels, which is heavy, and the truck has high requirements for light weight in order to carry more goods. Can be implemented with a highly lightweight framework

[0007] 1. The traditional frame is welded by many section steels, and it is heavy. In order to carry more goods, the truck has high requirements for light weight. Therefore, a frame that can not only install gas cylinders but also be highly lightweight is needed to achieve

[0008] 2. The production of traditional frames is difficult, the cycle is long, and the consistency and appearance of welded parts are also poor;

[0009] 3. The traditional gas supply system must be assembled on site, which is difficult and time-consuming, and cannot be prepared in advance
