Abstract

The invention provides a large-volume seamless gas cylinder rotating-prevention fixing device for a large-pipe trailer, relating to a gas cylinder rotating-prevention device and used for solving the problem that a seamless gas cylinder is easy to rotate to cause the leakage of natural gas out of the gas cylinder when the large-volume seamless gas cylinder is transported by the traditional large-pipe trailer. The large-volume seamless gas cylinder rotating-prevention fixing device is characterized in that each compression device comprises a connecting block, two rubber piers, two pressing plates, four bolts and four first nuts, wherein the two rubber piers are symmetrically arranged at two ends of the connecting block by taking the central line of the connecting block as a reference, the two pressing plates are respectively arranged at the outer end faces of the two rubber piers, the bolts pass through the pressing plates and are in treaded connection with threaded holes, and the bolts are in treaded connection with the first nuts; two flange fixing frames are respectively arranged at two longitudinal ends of a containerization frame, each flange fixing frame is vertically provided with two rows of flanges and horizontally provided with a plurality of flanges, and a plurality of compression devices are arranged in the containerization frame. The device is used for gas cylinder fixing in the transportation process of a 20-25MPa compressed natural gas large-pipe trailer.

Description

technical field [0001] The invention relates to a gas cylinder anti-rotation device. Background technique [0002] As my country's demand for clean energy increases, the demand for natural gas will increase. Natural gas is a high-quality, efficient and clean energy, and pipeline transportation is the basic way of natural gas. Since the construction of main gas transmission lines is restricted by comprehensive factors such as urban gasification conditions, economic strength, and user gas price tolerance, it is difficult to connect the main gas transmission lines to the Internet, and the scope of supply is limited, and gas can only be supplied to cities and towns along the long-distance pipeline. Therefore, the demand for natural gas in small and medium-sized cities and towns around long-distance pipelines will be met by using compressed natural gas (CNG), that is, natural gas will be purified and compressed, stored in special large-volume seamless gas cylinders, and transpor...
