Technical Field

The invention relates to the technical field of gas cylinder tools, in particular to a movable gas cylinder frame and a using method thereof.

Background

The gas cylinder is used for canning oxygen or natural gas and other industrial gases, is convenient and flexible to use, and is widely applied to welding operation and other industrial production. However, the working site is often unsatisfactory in surrounding environment, many obstacles exist, the moving is difficult, the ground flatness is poor, the open site is easily blown and scraped by strong wind, the gas cylinder is unstable to place, and certain potential safety hazards exist.

Therefore, a special gas cylinder frame for placing a gas cylinder is also provided in the prior art, and the special gas cylinder frame consists of a bottom plate and a U-shaped opening enclosing frame vertically arranged on the bottom plate, wherein a chain rope is hung at the U-shaped opening part to enclose the gas cylinder in the enclosing frame. The gas cylinder frame with the structure has the following defects when in use:

one is poor mobility. When the gas cylinder and the gas cylinder frame need to be moved, the gas cylinder and the gas cylinder frame need to be moved to a required position by using a transport tool.

Secondly, the safety is poor. The gas cylinder only surrounds with the chain after placing the gas cylinder frame, can produce rocking of gas cylinder under blowing of strong wind when open place is used, and violent rocking of gas cylinder can produce great impact force in the twinkling of an eye to the gas cylinder frame, and this kind of impact damages gas cylinder and bottle frame on the one hand easily, and on the other hand leads to the unstable potential safety hazard of empting suddenly even appearing of bottle frame easily.

Disclosure of Invention
