Technical Field

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

[0002] A fire hose is a soft roller used to transport flame-retardant liquids such as high-pressure water or foam. Traditional fire hoses are lined with rubber and the outer surface is wrapped with linen woven fabric. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints on both ends of the fire hose, which can be connected to another rubber hose, polyurethane hose, or PVC fire hose to extend the distance or connect a nozzle to increase the liquid spray pressure.

[0003] The invention discloses a fire-fighting hose winding device, comprising a base plate, a rear caster and a front caster are installed at the bottom of the base plate, a driving wheel is fixedly connected to one side of the rear caster, the driving wheel is connected to the driven wheel through a belt, the driven wheel is fixedly connected to the outer wall of the driving shaft, the outer wall of the driving shaft is rotatably connected to the top of the supporting side plate through a bearing, the supporting side plate is fixedly connected to the base plate, a rotating groove is opened at one end of the driving shaft, a rotating block is rotatably connected in the rotating groove, this fire-fighting hose winding device is different from the prior art, the water hose does not need to be dragged on the ground, the difficulty of winding is reduced, and the wear of the water hose is avoided, ensuring that the water hose remains in a close state during the winding process, and is not easy to be scattered after winding, and the water hose can be squeezed by two squeezing rollers to squeeze out the residual water liquid in the water hose, thereby improving the winding effect, and the water hose can be wound in the center by two correction rollers, and the winding is more neat.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the fire hose needs to be rewound after use, manual rewinding is prone to disorder and the rewinding effect is poor. When a rewinding device is used to rewind the water hose, it is necessary to use manual or electric methods to achieve the rewinding operation. During the rewinding process, the water hose needs to be dragged on the ground. On the one hand, it is difficult to rewind while dragging, and on the other hand, it is easy to cause wear to the water hose.

[0005] However, the reeling device used in the above equipment is relatively large. When the water hose inside the indoor fire hydrant box needs to be reeled in, the equipment cannot enter in some narrow places, making it impossible to reel in the water hose. In addition, in order to quickly carry out firefighting work, most fire hoses are connected to the fire hydrants inside the indoor fire hydrant box for a long time. Therefore, the above equipment needs to disassemble the water hose when reeling it in, which increases the reeling time of the operator and has certain limitations. For this reason, we propose a new water hose reeling device for fire engineering. Utility Model Content

When the firefighting operations are completed and the water hose needs to be wound up, the operator places the water hose inside the limit rod 8, and then the operator presses the control button 10, so that the control button 10 starts the drive motor 603 through the wire, and then the output end of the drive motor 603 drives the drive gear 602 to rotate, and then the meshing driven gear 601 rotates through the drive gear 602, and then the driven gear 601 drives the winding roller 4 to rotate through the support plate 5 and the bearing, so that the winding roller 4 drives the limit rod 8 to wind up the water hose. While winding up, the movable roller 702 and the fixed roller 701 squeeze out the liquid inside the water hose, so that the wound water hose can be more compact, thereby improving the convenience of the operator's winding up.

[0037] In summary, the fire-fighting engineering water hose winding device is provided with a winding groove 3, a winding roller 4, a support plate 5, a transmission mechanism 6 and an extrusion assembly 7. The support plate 5 and the fire hydrant box 1 are first fixedly installed, and then the winding roller 4 is movably installed with the support plate 5 through a bearing, so that the winding roller 4 can rotate stably. When the operator needs to use the water hose, the operator draws out the water hose through the winding groove 3. When the use is over, the transmission mechanism 6 drives the winding roller 4 to rotate through the support plate 5 and the bearing, and then the winding roller 4 rewinds the water hose through the winding groove 3, thereby improving The operator can reel in the water hose conveniently. While reeling in the water hose, the squeezing component 7 squeezes out the liquid inside the water hose, so that the reeled water hose can be tighter. This solves the problem that the reeling device used in the above-mentioned equipment is relatively large. When the water hose inside the indoor fire hydrant box needs to be reeled in, the equipment cannot enter in some narrow places, making it impossible to reel in the water hose. In order to quickly carry out firefighting work, most fire hoses are connected to the fire hydrants inside the indoor fire hydrant box for a long time. Therefore, the above-mentioned equipment needs to disassemble the water hose when reeling in, which increases the reeling time of the operator.
