Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinder transportation, in particular to a trolley for safely transporting special gas cylinders. Background Art

[0002] A large amount of special gases needed in the semiconductor, chemical and other industries are usually stored in special gas cylinders made according to certain requirements. Special gas cylinders need to be stored and transported according to certain requirements. It is necessary to ensure that the gas cylinders are placed firmly during storage. When using special gases, the gas cylinders are transported from the storage place to the use place. During transportation, the gas cylinders must be kept from tipping over and as stable as possible without shaking.

[0003] For example, the patent with publication number CN204020941U discloses a gas cylinder cart, which specifically discloses "a gas cylinder cart, which includes a cart frame, a cart handle and wheels, the cart handle is fixed to one side of the cart frame; the cart frame is provided with an inclined support rod on the side away from the cart handle; a flexible load-bearing belt is connected between two parallel support rods; a gas cylinder lifting device is provided on the top of the cart frame, and the gas cylinder lifting device includes a sliding sleeve arranged on the top of the cart frame; a sliding rod is matched in the sliding sleeve, and a hook is fixedly connected to the top of the sliding rod; a positioning hole is provided on the side of the sliding sleeve, and the sliding rod is fixedly connected to the top of the sliding rod; a positioning hole is provided on the side of the sliding sleeve, and a positioning hole is provided on the side of the sliding sleeve. An adjustment through hole is provided on the side of the rod, and the locating pin passes through the locating hole and one of the adjustment through holes. The technical solution realizes the technical effect that "the utility model adopts a support rod and a flexible load-bearing belt to prevent the gas cylinder from shaking during transportation, and can hold gas cylinders of different specifications. The combination of the sliding sleeve and the sliding rod can hoist gas cylinders of different heights, thereby improving the hoisting efficiency. During transportation, the gas cylinder lies obliquely on the cart, which has a low requirement on the height of the cart, reduces the weight of the cart, and reduces the volume of the cart, making the cart structure simpler and the failure rate low."

[0004] However, the device does not take multiple insurance measures to protect the gas cylinders, the protection measures are weak, the protection prospects are not optimistic, and the equipment pushes the gas cylinders at an angle, which is more likely to cause safety accidents during the transportation of gas cylinders. There is room for improvement. Utility Model Content
