Description

Technical Field

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

[0002] After each use, the fire hose needs to be manually rolled up for the convenience of the next use. After searching, the Chinese patent authorization number CN217886862U discloses a winding device, which rotates the rotating wheel through the operation of the motor, and the rotation of the rotating wheel rotates the first rotating shaft, and then the first rotating shaft rotates to roll up the fire hose, so as to achieve the purpose of not requiring manual winding, reducing manpower consumption. Although the device can discharge the residual water inside the fire hose, the spacing between the rollers that squeeze the hose is not adjustable. Since the fire hose has different thicknesses, when the thinner hose is rolled up, a gap will be caused between the roller and the hose, and the water inside the hose cannot be fully discharged. At the same time, the thicker hose is difficult to insert between the two rollers, which makes the installation of the hose more troublesome. At the same time, when the hose is being wound up, one end is stuck or pressed by a ground obstacle, but the other end is still being rolled up, which will cause the hose to be pulled, and then easily cause the hose to be damaged. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a fire hose winding device, which solves the problem that the spacing between the rollers for squeezing the hose in the prior device proposed in the background technology is not adjustable.

[0010] The utility model provides a fire hose reeling device, which has the following beneficial effects:

[0011] (1) A fire hose winding device, when in use, fixes one end of the hose to the winding wheel, and passes the hose between the upper roller and the lower roller. Under the action of the cylinder, the connecting plate is pushed downward, and then the connecting plate compresses the first spring downward and pushes the roller frame downward, so that the roller frame can drive the upper roller to move downward to squeeze the hose on the surface of the lower roller, thereby facilitating the water inside the hose to be squeezed out when winding. At the same time, it can be suitable for hoses of various thicknesses.

[0012] (2) A fire hose winding device, when winding the fire hose, drives the winding wheel to rotate through the driving motor, and then the winding wheel drives the fire hose to be wound. When the other end of the fire hose is stuck or pressed and cannot move, the fire hose will be tightened under the pulling force of the winding wheel. When the fire hose is tightened, the lower roller will be subjected to downward pressure, and then the lower roller and the bottom of the lifting frame will move downward through the telescopic rod and compress the second spring, so that the bottom of the lifting frame will contact and press down with the push switch, so that the push switch can turn off the driving motor to stop rotating, and then stop winding, so as to avoid the fire hose being damaged by forced winding and pulling.

[0013] Thereby, the problem that the spacing between the rollers of the existing device for squeezing the water hose is not adjustable is solved. Since the fire hoses have different thicknesses, when the thinner water hose is rolled up, a gap will be caused between the roller and the water hose, and the water inside the water hose cannot be fully discharged. At the same time, the thicker water hose is difficult to insert between the two rollers, which makes the installation of the water hose more troublesome. At the same time, when the water hose is being wound up, one end is stuck or pressed by a ground obstacle, but the other end is still being rolled up, which will cause the water hose to be pulled, and then easily cause the water hose to be damaged.

The device body 1 has one end; a lifting frame 8 is arranged on the top, a cylinder 11 is installed on the top of the lifting frame 8, and the telescopic end of the bottom of the cylinder 11 is connected to the connecting plate 20, a roller frame 13 is arranged below the connecting plate 20, an upper roller 7 is arranged at the bottom of the roller frame 13, and the two ends of the upper roller 7 are rotatably connected to the two sides of the roller frame 13, a lower roller 9 is arranged below the upper roller 7, and the two ends of the lower roller 9 are rotatably connected to the two sides of the bottom of the lifting frame 8 When the device is used, one end of the water hose is fixed to the reel 4, and the water hose is passed between the upper roller 7 and the lower roller 9. Under the action of the cylinder 11, the connecting plate 20 is pushed downward, and then the connecting plate 20 compresses the first spring 10 downward, and pushes the roller frame 13 to move downward, so that the roller frame 13 can drive the upper roller 7 to move downward to squeeze the water hose on the surface of the lower roller 9, which is conducive to squeezing out the water inside the water hose when it is reeled in, and can be suitable for water hoses of various thicknesses, thereby solving the problem that the spacing between the rollers of the existing device for squeezing the water hose is not adjustable. Since the fire hoses have different thicknesses, when the thinner water hoses are rolled up, there will be a gap between the rollers and the water hoses, and the water inside the water hoses cannot be fully discharged.

[0023] Embodiment 2:

[0024] Limit rods 12 are welded to both ends of the top of the roller frame 13, and the outer wall of the limit rod 12 is in sliding contact with the connecting plate 20. A first spring 10 is mounted on the outside of the limit rod 12, and a circular protrusion structure is provided on the top of the connecting plate 20, which is beneficial to limit the lifting and lowering of the roller frame 13, and further beneficial to enable the roller frame 13 to maintain vertical lifting and lowering. The first spring 10 is beneficial to prevent the upper roller 7 from exerting excessive downward pressure on the water hose body 5, causing damage to the water hose body 5.

[0025] Embodiment 3:

[0026] The two ends of the bottom of the lifting frame 8 are welded to the top of the telescopic rod 15, the bottom of the telescopic rod 15 is welded to the top of the device body 1, and a second spring 16 is sleeved on the outside of the telescopic rod 15.

The push-type switch 14 is installed in the groove at the top of the device body 1, and the push-type switch 14 protrudes from the groove at the top of the device body 1. When the device reels the water hose body 5, the reel 4 is driven by the driving motor 3 to rotate, and then the reel 4 drives the water hose to be reeled. When the other end of the hose body 5 is stuck or pressed and cannot move, the hose body 5 will be tightened under the pulling force of the reel 4. When the hose is tightened, the lower roller 9 will be subjected to downward pressure, and then the lower roller 9 and the bottom of the lifting frame 8 will move downward through the telescopic rod 15 and compress the second spring 16, so that the bottom of the lifting frame 8 will contact and press down with the push-type switch 14, so that the push-type switch 14 can turn off the drive motor 3 to stop rotation, and then stop further reeling, to prevent the hose from being damaged by forced reeling.

[0027] Embodiment 4:

[0028] Baffles are provided on both sides of the reel 4, and a slot 17 is opened on the surface of the reel 4. The slot 17 is snap-connected with one end of the hose body 5. By inserting one end of the hose body 5 into the reel 4 through the slot 17, the reel 4 can fix one end of the hose body 5. The baffles on both sides of the reel 4 are helpful for limiting the position of the hose body 5 when it is reeled.

[0029] Embodiment 5:

[0030] A connecting hole 18 is provided on one side of the reel 4, and the connecting hole 18 is threadedly connected to a latch 19, and one end of the bottom of the latch 19 is inserted into the outside of the output end of the drive motor 3. A hole groove is provided on the surface of the output end of the drive motor 3. There is a gap between the reel 4 and one side of the device body 1. By rotating the latch 19, the latch 19 can be removed from the reel 4, and then one end of the latch 19 is detached from the output end of the drive motor 3, so that the reel 4 can be removed.

[0031] Working principle: When the device is in use, one end of the water hose is fixed to the reel 4, and the water hose is passed between the upper roller 7 and the lower roller 9. Under the action of the cylinder 11, the connecting plate 20 is pushed downward, and then the connecting plate 20 compresses the first spring 10 downward, and pushes the roller frame 13 to move downward, so that the roller frame 13 can drive the upper roller 7 to move downward to squeeze the water hose on the surface of the lower roller 9, which is conducive to squeezing out the water inside the water hose when it is reeled in. At the same time, it can be suitable for water hoses of various thicknesses, thereby solving the problem that the spacing between the rollers of the existing device for squeezing water hoses is not adjustable. Due to the different thicknesses of fire hoses, when a thinner water hose is rolled up, a gap will be caused between the roller and the water hose, and the water inside the water hose cannot be fully discharged. The device is suitable for adjusting the water hose itself. When the hose body 5 is being reeled in, the reeling wheel 4 is driven to rotate by the driving motor 3, and then the reeling wheel 4 drives the water hose to be reeled in. When the other end of the water hose body 5 is stuck or pressed and cannot be moved, the water hose body 5 will be tightened under the pulling force of the reeling wheel 4. When the water hose is tightened, the lower roller 9 will be subjected to downward pressure, and then the lower roller 9 and the bottom of the lifting frame 8 will move downward through the telescopic rod 15 and compress the second spring 16, so that the bottom of the lifting frame 8 will contact and press down with the push-type switch 14, so that the push-type switch 14 can turn off the driving motor 3 and stop rotating, and then stop further reeling, to avoid the water hose being damaged by forced reeling, and by rotating the latch 19, the latch 19 can be removed from the reeling wheel 4, and then one end of the latch 19 is separated from the output end of the driving motor 3, so that the reeling wheel 4 can be removed.
