Large-capacity gas cylinder torque testing device

Abstract

The invention provides a large-capacity gas cylinder torque testing device. The large-capacity gas cylinder torque testing device comprises a fixed baffle, a torque tester, a tooling, a supporting device, a chuck, a hydraulic retractable device and a rotating device, wherein the tooling comprises a first tooling and a second tooling. A gas cylinder connected with the tooling and the torque tester is placed on the supporting device, then the chuck is installed on the first tooling and then is connected with the hydraulic retractable device, the rotating device connected with the hydraulic retractable device drives a torque sensor of the torque tester to rotate, the torque sensor is fixedly arranged on the fixed baffle, then the chuck end of the hydraulic retractable device is separated from the chuck, thus the torque value produced by rotation due to bending and non-roundness of the gas cylinder can be tested through the torque tester, whether the torque value of the gas cylinder satisfies the standard or not can be detected and the accidents possibly caused by overlarge torque of the gas cylinder can be effectively avoided. Moreover, the device is simple to operate, can realize quick detection and can meet the market demand.

Description

technical field [0001] The invention relates to a torque testing device, in particular to a large-volume gas bottle torque testing device. Background technique [0002] A gas cylinder is a mobile pressure vessel that can be refilled and utilized, and it is widely used in countries all over the world. In recent years, with the development of my country's industry, the long-tube trailers that use large-volume gas cylinders to transport industrial compressed gas have grown rapidly. From 2000 to 2008, the average annual growth rate of long-tube trailers with large-volume gas cylinders in my country reached 49.74%. The number of large-volume gas cylinder long-tube trailers in my country is close to 10,000, and about 99% of them are used to transport compressed natural gas and compressed hydrogen, two flammable and explosive industrial gases. [0003] Due to the influence of factors such as the curvature and out-of-roundness of the cylinder body, large-volume cylinders are usually...

AI Technical Summary

Problems solved by technology

Under the action of torque, large-volume gas cylinders may rotate significantly, resulting in significant deformation or even breakage of the external pipes fixedly connected to the gas cylinders, which in turn may cause leakage of the internal medium of the gas cylinders, and serious accidents such as combustion and explosion may occur

[0004] In order to avoid possible accidents caused by the excessive torque of the gas cylinder itself, it is necessary to test the torque of the large-volume gas cylinder before leaving the factory and putting it into use and during regular inspections in service to check whether the torque of the gas cylinder meets the standard. However, There is no device capable of testing the torque of large volume gas cylinders in the prior art
