Description
Technical Field
[0001] The utility model relates to the field of oil bag storage and retrieval devices, in particular to an oil bag loading, unloading and transporting mechanism. Background Art
[0002] The oil bladder is a soft container for liquid goods such as diesel, gasoline, and jet fuel. It is usually used to quickly arrange oil depots during field travel. When not in use, the oil bladder needs to be folded and placed. The folded dimensions of a 400-cubic-meter soft oil bladder are approximately 4.2 m×0.95 m×0.65 m, and the mass is approximately 1,070 kg. The oil bladder is transported to the designated location via a vehicle-mounted cabin. When in use, it is taken out of the cabin and unfolded. After use, it needs to be folded and put back into the cabin.
[0003] A large toolbox is usually placed in the existing cabin, and the soft oil bladder is placed inside the toolbox. When using the oil bladder, the toolbox is moved out of the cabin, and then the oil bladder is taken out of the toolbox. After use, the oil bladder is placed in the toolbox, and then the toolbox is placed in the cabin. Because the size and weight of the oil bladder are large, the toolbox needs to be taken out of the cabin by a forklift, which is a laborious process and troublesome to operate. In order to ensure safety during vehicle transportation, the toolbox should be effectively fixed after being retracted into the cabin. For heavier toolboxes, bolts are usually used for fixing. The space in the cabin is limited, and the removal and installation of the bolts are cumbersome. The toolbox is closed on all sides, and the soft oil bladder has an irregular shape after being folded. It is easy to be too large in size, which makes it difficult to place the oil bladder in the toolbox. When there is no construction machinery such as a forklift at the work site, the transfer of the toolbox and the oil bladder cannot be achieved by manual labor alone. Therefore, how to manually load and unload the oil bladder has long been a difficult problem to solve. Summary of the invention
