Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to a fire hydrant hose winding device. Background Art

[0002] A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. It needs to be rewound together during use to facilitate transportation and next use.

[0003] After the existing fire hose is used, clean water or foam will remain inside. Since there is no drainage device, the clean water needs to be drained manually when it is rolled up, which consumes a lot of manpower. In addition, since only a pair of universal wheels is provided, the rear end of the device needs to be lifted by the handle when moving the device.

[0004] For example, a fire hydrant hose winding device disclosed in Chinese patent CN218708085U can select manual or automatic winding according to the usage scenario. Manual winding requires human power to rotate the rotating handle to drive the winding shaft to rotate. Automatic winding requires connecting a power source and then starting the power motor to drive the winding shaft to rotate. The rotation of the winding shaft will wind up the fire hose, so that the fire water pipe can still be wound without electricity. The return spring can provide a certain thrust for the limit block. The limit block will drive the second extrusion roller to approach the first extrusion roller due to the thrust, thereby squeezing the fire water hose between the first extrusion roller and the second extrusion roller. When the fire water hose passes between the second extrusion roller and the first extrusion roller, the remaining clean water and foam inside the fire water pipe will be squeezed out, and there is no need for human power to remove the clean water and foam inside the fire water pipe.

[0005] However, after use, gravel and other particles will adhere to the surface of the fire hose. When the fire hose is rolled up, friction and extrusion between the gravel particles will occur, which will cause damage to the fire hose and affect the subsequent use of the fire hose.

[0006] For this reason we urgently need to provide a kind of fire hydrant hose reeling device. Utility Model Content
