Description

Technical Field

[0001] The present invention relates to the technical field of acetylene cylinder transportation equipment, and more specifically, to a safety acetylene cylinder trolley. Background Art

[0002] Acetylene is an organic compound and a basic raw material for manufacturing acetaldehyde, acetic acid, rubber, fiber and other products. Acetylene has a low boiling point and generates high temperatures when burned. Therefore, strict safety supervision is required in the process of using acetylene gas in the industrial manufacturing field, and acetylene cylinders are usually used for storage. At the same time, it is required that the ambient temperature of acetylene should not exceed 40°C, the tilt angle of the bottle should not exceed 30°, the output gas pressure of the bottle should not be greater than 0.15MPa, and the bottle should not have static electricity, etc. Since the acetylene cylinder is heavy, it needs to be moved with the help of a trolley during temporary transfer, and sometimes it needs to be temporarily stored on the trolley. However, the existing trolley has a simple structure, vibrates greatly during movement, and the acetylene cylinder has a large tilt angle during movement, which poses a great safety hazard.

[0003] In order to reduce the potential safety hazard during transportation, a patent application with the authorization announcement number CN114803100B discloses an oxygen and acetylene safety transport cage, which clamps the acetylene cylinder by setting a limit frame to prevent the cylinders from colliding or falling during transportation, thereby ensuring the safety of transportation. However, such a structure will still cause the acetylene cylinder to tilt when passing through a slope, that is, the potential hazard caused by the tilt of the acetylene cylinder has not been resolved.

[0004] Therefore, there is an urgent need for a safe acetylene cylinder trolley that can prevent the acetylene cylinder from tilting too much during the transfer process. Summary of the invention
