Description

Technical Field

[0001] The utility model relates to the technical field of inspection and analysis instruments, in particular to a Dewar flask handling trolley. Background Art

[0002] Inspection and analysis instruments require a large amount of high-purity gas. When laboratories use these gases, they mostly use high-pressure gas cylinders and Dewar flasks for storage. When using high-pressure gas cylinders, due to their small volume and light weight, they are convenient to use and replace. However, for some gases with higher purity requirements and larger usage amounts, Dewar flasks are generally used for storage. The advantages of using Dewar flasks to store gases are their large storage capacity, low storage pressure, and long replacement cycle. However, due to their large weight after being filled with gas, it is not conducive to the operator's use and handling. Content of the Utility Model

[0003] In view of the above-mentioned technical problems, a Dewar flask handling trolley is provided. When the utility model is in use, the trolley is pushed to place the Dewar flask in the U-shaped limiting frame, the lifting hooks are hung on the left and right sides of the Dewar flask lifting ring, and the rising pressure rod is continuously stepped on with the foot. The hydraulic cylinder pushes the hydraulic rod to move vertically upward, thereby lifting the Dewar flask off the ground. Then the trolley is pushed again to transport the Dewar flask to the destination, and the lowering pressure rod on the push rod is released, and the Dewar flask descends to the ground, completing the handling work of the Dewar flask. The technical means adopted by the utility model are as follows:

[0004] A Dewar flask handling trolley includes: a U-shaped base, a hydraulic cylinder, a hydraulic rod, a lifting frame, a chain, a lifting hook, a U-shaped limiting frame, a push rod and a traveling mechanism.

The upper end of the hydraulic rod is connected to the lifting frame. At least two chains are connected to the lifting frame, and each chain is connected with a lifting hook. The U-shaped limiting frame is connected to the hydraulic cylinder and has a U-shaped structure. The push rod is connected to the hydraulic cylinder and is located above the U-shaped limiting frame.

[0005] Further, the traveling mechanism includes universal wheels and directional wheels. The universal wheels are installed on one side of the U-shaped base, and the directional wheels are installed on the other side of the U-shaped base.

[0006] Further, the U-shaped base has a U-shaped structure and includes a longitudinal frame and transverse frames connected to both ends of the longitudinal frame. The hydraulic cylinder is installed in the middle of the longitudinal frame.
