The invention discloses a sulfur hexafluoride gas pipeline storage and transport trolley. The sulfur hexafluoride gas pipeline storage and transport trolley comprises a base with casters at the bottom; a storage box with an upward opening is fixedly arranged on the base; a bracket extending above the storage box is also mounted on the base; and a locking device for locking a port of a sulfur hexafluoride gas pipeline is mounted at the upper end of the bracket. The locking device comprises a fixed seat and a movable seat, wherein the fixed seat is fixedly arranged on the bracket; and the movable seat corresponding to the fixed seat is arranged under the fixed seat; an upper clamping opening, which is matched with the upper part of the port of the sulfur hexafluoride gas pipeline in a clamped manner, is formed in the bottom of the fixed seat; upper screw holes are respectively formed in positions, on two sides of the upper clamping opening, on the fixed seat; a lower clamping opening, which is matched with the lower part of the port of the sulfur hexafluoride gas pipeline in a clamped manner, is formed in the top surface of the movable seat; lower through holes corresponding to the upper screw holes are respectively formed in positions, on the two sides of the lower clamping opening, on the movable seat; and studs matched with the upper screw holes in a screwed manner are inserted in the lower through holes. The sulfur hexafluoride gas pipeline storage and transport trolley can rapidly place the sulfur hexafluoride gas pipelines with various lengths and thicknesses and has the advantages of convenient classification and storage, convenient movement, convenient taking and small floor space occupied during idling.
