Technical Field
The invention relates to a hose reel capable of feeding liquid from two sides, and belongs to the technical field of reels.
Background
The reel is used for coiling the hose, and the hose is pulled out from the reel when required, and the hose is retracted from the reel after the hose is used.
The existing hose reel can not meet the requirements of equipment vehicles, particularly military vehicles, and the army needs to quickly refuel equipment in the process of realizing the refueling of military equipment clusters, so that the hose can be orderly and quickly recovered and stored after the refueling operation is finished, and the hose is ready for next refueling.
Firstly, because the existing hose reel is not provided with a rapid automatic recovery device, or the automatic recovery device is unreasonable, the hose cannot be completely wound in place; secondly, the hose reel with the automatic recovery device requires an operator to apply force all the time to prevent the hose from being recovered after the hose is pulled out, so that the winding efficiency of the hose is improved to a certain extent, the labor intensity of the operator is also increased, the hose is constantly and continuously stressed, and the service life of the hose is reduced; moreover, the existing hose reel can only be used for liquid passing on one side (left or right), has poor adaptability, and is difficult to meet the diversified requirements of oiling occasions. Finally, along with the rotation of the reel, the liquid-passing hose is easy to twist, and the inner diameter of the twisted liquid-passing hose is reduced, so that the liquid-passing efficiency is affected, and the service life of the liquid-passing hose is further reduced.
