Oxygen bottle trolley

Abstract

The invention relates to an oxygen bottle trolley. The oxygen bottle trolley comprises a frame and a clamping device which is arranged on the frame, wherein the clamping device comprises holding claws which are arranged in pairs in an opening and closing manner; a carrying rod is movably assembled on the frame along a vertical guide direction; both the upper and lower ends of the carrying rod extend out of the frame; the upper end of the carrying rod is fixedly connected with a handle, and the lower end of the carrying rod is fixedly connected with an oxygen bottle carrying plate; the middle upper part of the carrying rod is fixedly connected with a wedged plate which moves vertically along with the carrying rod and of which the upper part is wider than the lower part; the holding claws are fixedly connected with force application arms which are positioned in a vertical movement stroke of the wedged plate and are ejected by the wedged plate. According to the oxygen bottle trolley, the carrying rod can move up and down with the gravity change caused by loading or unloading of an oxygen bottle, so that the wedged plate on the carrying rod can descend and push the force application arms on the movable claws to drive the movable claws to close so as to automatically clamp the oxygen bottle, and the wedged plate ascends without pushing the movable claws to enable the movable claws to be restored and opened when the carrying rod ascends; thus the clamping and loosening of the oxygen bottle are automatically realized, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the field of gas cylinder transportation, in particular to a gas cylinder trolley. Background technique [0002] At present, in order to ensure the safety of the transportation process, gas cylinders should be fixed on the carts when carts are used to transport gas cylinders, so as to prevent accidents of injuring people due to gas cylinders falling over. In the prior art, chains, belts or steel rings are usually used as clamping devices to fix gas cylinders. Chinese patent CN203450148U discloses a trolley for safe oxygen cylinders and acetylene cylinders. The trolley is provided with gas cylinder grooves for placing gas cylinders on the frame, and gas cylinder fixing arc-shaped spring pieces are arranged on both sides of the gas cylinder grooves as clips. holding device to secure the cylinder. When using this kind of trolley to transport gas cylinders, on the one hand, the arc-shaped springs cannot clamp the gas cylinders fi...

AI Technical Summary

Problems solved by technology

When using this kind of trolley to transport gas cylinders, on the one hand, the arc-shaped springs cannot clamp the gas cylinders firmly, and the gas cylinders must be stabilized manually during transportation. Because the gas cylinders are very heavy, once they are not stabilized, they will It will fall over; on the other hand, the arc-shaped spring piece cannot be clamped and loosened automatically, and it needs to be done manually when installing and disassembling the gas cylinder

Therefore, the gas cylinder trolley in the prior art has not only increased the labor intensity of the staff, but also has hidden dangers to its personal safety.
