Description

Technical Field

[0001] The utility model belongs to the field of transportation technology, in particular to a device for moving a plurality of large-scale measuring cylinders. Background Art

[0002] In actual production processes or experiments, large measuring cylinders are often needed for quantitative measurement. During the transportation process, due to their large caliber and lack of sealing devices, it is easy to cause the liquid to spill and collide during transportation. When large-scale transfer is required, manual methods are usually used, but only one person can carry a maximum of two measuring cylinders at a time, which is inefficient. When using a cart for transportation, due to the instability during transportation, it is easy to cause liquid overflow or container collision, which increases work risks and poses great safety hazards.

[0003] Through searching, it is found that the following patents are similar to the technical solution of this utility model:

[0004] Application number CN201620696034.3 discloses a multi-specification measuring cylinder storage rack, including an upper plate, an upper hole is provided at its upper end; a middle plate, which is fixed below the upper plate, and a middle hole is provided at its upper end; a lower plate, which is fixed below the middle plate, and a lower hole, a middle positioning hole and an upper positioning hole are provided at its upper end; a lower positioning plate, which is fixed below the lower plate, and a lower positioning hole is provided at its upper end, and the lower positioning hole is coaxial with the lower hole; a water filter support plate, which is fixed below the lower positioning plate, and its upper end is horizontal and provided with a plurality of drainage holes. The multi-specification measuring cylinder storage rack described in the utility model has a simple structure and is easy to use and clean. It can not only store measuring cylinders of various specifications well, but also ensure that the measuring cylinders will not collide with each other, and can effectively protect the measuring cylinders. However, it is found in the actual use process that when it is necessary to carry measuring cylinders of the same model, multiple handling is required, which is relatively inefficient, and collisions due to unstable center of gravity are prone to occur during the handling process, causing accidents.
