[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] The following is combined Figure 1-7 This utility model describes a fire hose reel winding device, comprising: a base 1, a drive mechanism 2, and a winding mechanism 3, wherein:

[0032] The drive mechanism 2 is mounted on the base 1.

[0033] The take-up mechanism 3 includes a fixed take-up fork 31 and a movable take-up fork 32. The fixed take-up fork 31 is connected to the power output end of the drive mechanism 2. The fixed take-up fork 31 is provided with a first insertion part 311, and the movable take-up fork 32 is provided with a second insertion part 321. The second insertion part 321 includes a first state of being inserted into the first insertion part 311 and a second state of being separated from the first insertion part 311.

[0034] When the second plug portion 321 is in the first state, the first plug portion 311 and / or the second plug portion 321 form a fixing portion 33 for fixing the end of the fire hose.

[0035] In this invention, the second insertion part 321 and the first insertion part 311 are inserted and cooperated to form a fixing part 33 for fixing the end of the fire hose. The end of the fire hose is fixed by the fixing part 33. The fixed winding fork 31 and the movable winding fork 32 are rotated by the driving mechanism 2 to complete the winding of the fire hose. By separating the second insertion part 321 from the first insertion part 311, the fire hose rolled into a disc can be disassembled, which facilitates the handling of the rolled-up disc fire hose and improves the reliability of use.

[0036] The fire hose reeling device provided by this utility model solves the problems existing in the prior art by setting a drive mechanism 2 and a unique reeling mechanism 3 on the base 1. The reeling mechanism 3 adopts a combination design of a fixed reeling fork 31 and a movable reeling fork 32, and realizes the conversion between two working states through the cooperation of the first insertion part 311 and the second insertion part 321. In practical applications, when firefighters need to reel in the fire hose, they first insert the second insertion part 321 of the movable reeling fork 32 with the first insertion part 311 of the fixed reeling fork 31 to form the first state. At this time, the fixed part 33 formed between the two can firmly clamp the end of the fire hose. This design greatly improves the stability and reliability of the reeling process and avoids the problem of the hose end easily falling off in traditional reeling devices. After the hose is reeled in, the operator can separate the movable reeling fork 32 (second state) and easily take out the coiled fire hose. This detachable design not only simplifies the picking and putting process, but also reduces the labor intensity of firefighters, especially in emergency rescue situations, and can significantly improve work efficiency. In addition, the structure is simple, robust, and durable, making it easy to maintain and service daily.

[0037] like Figure 2As shown, specifically, the drive mechanism 2 includes a geared motor and a rotating shaft. The geared motor drives the rotating shaft to rotate via a synchronous belt. The rotating shaft is connected to a fixed take-up fork 31 and is used to drive the fixed take-up fork 31 to rotate, thereby completing the fire hose take-up operation. Connecting the geared motor and the rotating shaft via a synchronous belt can effectively reduce the axial space occupied by the rotating shaft, thereby reducing the overall space occupied by the device.

[0038] Furthermore, the drive mechanism 2 also includes a crank handle that is detachably connected to the rotating shaft. It can be driven by either a geared motor or by cranking the handle, and adopts a dual-mode for winding the fire hose. It can be used in an emergency when the geared motor cannot operate normally. Normally, the crank handle can be detached and then fixed to the rotating shaft when in use.

[0039] like Figure 3 As shown, in some embodiments, the first insertion part 311 includes two insertion rods 3111, and the second insertion part 321 includes two insertion tubes 3211. The two insertion rods 3111 are respectively used to insert into the two insertion tubes 3211; wherein, a fixing part 33 is formed between the two insertion tubes 3211.

[0040] In this invention, during the fire hose reeling process, two parallel insert rods 3111 are inserted into corresponding insert tubes 3211, forming a stable double-support connection. This double-support structure significantly improves connection stability, effectively preventing swaying or eccentricity during reeling. The fixing part 33 formed between the two insert tubes 3211 constitutes an ideal hose end fixing space, allowing the hose end to be securely held within this space, avoiding wear or deformation that might occur with single-point fixing. The mating structure of the insert rods 3111 and insert tubes 3211 has excellent self-centering characteristics, ensuring accurate alignment even during rapid operations, thus improving assembly efficiency. In actual fire rescue operations, this structural design ensures stable and reliable operation under various harsh environments (such as heavy rain and mud), while also facilitating quick assembly and disassembly by operators.

[0041] Specifically, by setting the second insertion part 321 as an insertion tube 3211 and the first insertion part 311 as an insertion rod 3111, a fixing part 33 for fixing the end of the fire hose is formed between the two insertion tubes 3211, so that the fire hose wound into a coil structure can be firmly fixed on the movable winding fork 32, making it convenient to separate the fire hose together when the movable winding fork 32 and the fixed winding fork 31 are separated, and making it easy to pick up and put away the wound fire hose.

[0042] The fixed retractor fork 31 and the movable retractor fork 32 adopt a single crossbeam structure. The two single crossbeams are arranged opposite each other, ensuring that they are horizontal during transportation. This effectively reduces the overall height of the device, thereby reducing the space occupied and facilitating adaptation to the loading requirements of fire trucks. The two oppositely arranged single crossbeams axially limit the fire hose, ensuring that the retracted fire hose is located between the two single crossbeams, preventing axial deformation of the fire hose and ensuring the stability of the fire hose retracting.

[0043] like Figure 3-5 As shown, in some embodiments, a positioning structure 34 is provided between the insertion tube 3211 and the insertion rod 3111. The positioning structure 34 is used to position the second insertion part 321 in the first state.

[0044] This embodiment of the invention incorporates a positioning structure 34 for precisely positioning the second insertion part 321 in its first state. In practical applications, the positioning structure 34 solves the problem of relative rotation or axial movement that easily occurs in traditional insertion structures. Even under significant centrifugal force and vibration during high-speed winding of the fire hose, the positioning structure 34 ensures that the movable winding fork 32 remains in the correct position. This design greatly improves the stability and safety of the winding process, avoiding winding quality problems caused by changes in the relative positions of components. Simultaneously, the presence of the positioning structure 34 provides clear assembly feedback to the operator; when the positioning structure 34 is in place, the operator can clearly perceive it, thus ensuring that each assembly achieves the expected installation effect.

[0045] Furthermore, the positioning structure 34 includes a positioning hole 341 disposed on the insertion tube 3211 and an elastic positioning pin 342 disposed on the insertion rod 3111, the elastic positioning pin 342 being used to engage with the positioning hole 341.

[0046] This embodiment of the invention specifically defines the positioning structure 34 as employing a positioning hole 341 and an elastic positioning pin 342. This design offers significant advantages in practical use: the elastic positioning pin 342 automatically compresses when inserted into the positioning hole 341, and recovers and locks under elastic force after insertion, achieving a fast and reliable positioning effect. Compared with traditional bolt fixing, this design greatly shortens assembly time, making it particularly suitable for time-sensitive situations such as fire rescue. The elastic positioning pin 342 also features a self-locking function, preventing it from falling off even under vibration conditions. Furthermore, the positioning hole 341 is carefully positioned to ensure that the movable rewind fork 32 remains completely coaxial with the fixed rewind fork 31 in the locked state, which is crucial for ensuring the uniformity and neatness of hose rewinding.

[0047] Specifically, the insertion rod 3111 has a mounting hole arranged radially, and the elastic positioning pin 342 is fixedly disposed in the mounting hole. The elastic positioning pin 342 includes a sleeve, a pin shaft disposed in the sleeve, and an elastic element. One end of the elastic element abuts against the pin shaft, and the other end abuts against the sleeve. The elastic element can be a spring, providing elastic support force for the pin shaft, so that the end of the pin shaft can extend to the outside of the sleeve for positioning and locking with the positioning hole 341. A limit ring is provided at the open end of the sleeve to limit the pin shaft, prevent the pin shaft from disengaging from the sleeve, and ensure that the pin shaft extends out of the sleeve by a specific length. The end of the pin shaft extending out of the sleeve has a smooth spherical structure, which can be squeezed against the edge of the positioning hole 341 to make the pin shaft engage with or disengage from the positioning hole 341. During the assembly of the movable take-up fork 32 and the fixed take-up fork 31, the insert rod 3111 is inserted into the insert tube 3211. By setting two insert rods 3111 and two insert tubes 3211, the elastic positioning pin 342 can be positioned. When the pin is aligned with the positioning hole 341, it extends under the elastic force of the elastic element and completes the assembly with the positioning hole 341. During the separation of the movable take-up fork 32 and the fixed take-up fork 31, by pulling the movable take-up fork 32, the edge of the positioning hole 341 is pressed against the spherical structure of the pin, thereby compressing the elastic element and pressing the pin into the sleeve, thus completing the separation of the movable take-up fork 32 and the fixed take-up fork 31.

[0048] like Figure 1 As shown, in some embodiments, the fixed take-up fork 31 and the movable take-up fork 32 adopt a single beam structure arranged opposite to each other, and the movable take-up fork 32 is provided with a handle 35 at the end away from the fixed take-up fork 31.

[0049] In this embodiment of the invention, a handle 35 is provided at the end of the movable retractor fork 32 away from the fixed retractor fork 31. This design, from an ergonomic perspective, significantly improves the operability of the device. The handle 35 is designed with the operational needs of firefighters wearing gloves in mind, employing appropriate dimensions and anti-slip treatment. In practical use, the handle 35 is not only used for routine assembly and disassembly operations but can also serve as a quick-release mechanism in emergencies, providing firefighters with additional safety. The position of the handle 35 is also optimized, facilitating the application of force without affecting the hose reeling process. Furthermore, the handle 35 can also serve as an auxiliary tool for moving the hose after reeling, reducing the workload of firefighters.

[0050] like Figure 7 As shown, in some embodiments, the base 1 includes: a base plate 11 for supporting the drive mechanism 2; and a roller 12 disposed at the bottom of the base plate 11, the roller 12 including a third state located at the bottom of the base plate 11 and a fourth state flipped over to the top of the base plate 11.

[0051] In this invention, the base 1 employs a reversible roller 12, enabling the device to operate in dual modes. When the roller 12 is in the third state (located at the bottom of the base plate 11), the device can be moved flexibly, facilitating adjustments to the working position or site changes. When the roller 12 is flipped to the fourth state (above the base plate 11), the base plate 11 directly contacts the ground, providing a more stable working condition. This design is particularly suitable for fire truck applications: in vehicle-mounted mode, the roller 12 can be retracted, reducing space occupation; during use, the roller 12 can be lowered for convenient equipment transport. The base plate 11 is also designed with anti-slip and load-bearing requirements in mind, ensuring stable operation under various ground conditions.

[0052] Specifically, a limiting hole is provided on the base plate 11, and a limiting rod 121 is provided on the roller 12. The limiting rod 121 is inserted into the limiting hole to keep the roller 12 stably in the third state. A support pad is also provided at the bottom of the base plate 11. When the roller 12 is flipped over to the top of the base plate 11, it is supported by the support pad.

[0053] The base plate is also equipped with a telescopic handrail 13, which facilitates the movement of the device. The height of the telescopic handrail 13 can be adjusted as needed to suit users of different heights.

[0054] In some embodiments, a flattening mechanism 4 is further provided on the base 1. The flattening mechanism 4 includes: a support column 41; an upper roller shaft 42 and a lower roller shaft 43, which are rotatably provided on the support column 41. The upper roller shaft 42 and the lower roller shaft 43 are arranged in parallel, and a gap for squeezing the fire hose is formed between the upper roller shaft 42 and the lower roller shaft 43.

[0055] In this invention, the flattening mechanism 4, through the cooperation of the upper and lower roller shafts 43, provides an effective pre-treatment function for fire hoses. In practical applications, when the fire hose passes through the flattening mechanism 4, the parallel upper and lower roller shafts 43 apply uniform pressure to the hose, not only squeezing out residual water but also pre-flattening the hose, creating favorable conditions for subsequent winding. This design significantly improves winding quality: firstly, removing residual water reduces the hose weight, lessening the winding burden; secondly, the flattening process makes it easier for the hose to form neat rolls, improving storage efficiency; and finally, the flattening process also allows for inspection of hose for damage, improving the timeliness of equipment maintenance.

[0056] In some embodiments, the support column 41 includes: a fixed support column 411 connected to the base 1; and an adjusting support column 412 slidably disposed along the extending direction of the fixed support column 411, wherein a fixing member 413 is disposed on the adjusting support column 412 for fixing the adjusting support column 412 on the fixed support column 411; wherein, the lower roller shaft 43 is disposed on the fixed support column 411 and the upper roller shaft 42 is disposed on the adjusting support column 412.

[0057] In this invention, the support column 41 adopts a combination design of a fixed support column 411 and an adjustable support column 412, realizing the height adjustment function of the flattening mechanism 4. In actual firefighting, it is often necessary to handle fire hoses of different specifications and conditions, and this adjustable design provides good adaptability. The adjustable support column 412 can be precisely positioned on the fixed support column 411 through the fixing member 413, ensuring that the distance between the upper and lower roller shafts 43 is always kept in the optimal working state. This design not only adapts to the flattening requirements of different types of fire hoses, but also adjusts the pressure according to the actual water content of the fire hose, avoiding excessive compression damage to the fire hose.

[0058] In some embodiments, the adjusting support column 412 is provided with a locking groove 4121, one end of the upper roller shaft 42 is rotatably connected to the adjusting support column 412, and the other end is provided with a locking part 421, which is used to engage with the locking groove 4121.

[0059] In this invention, a locking groove 4121 is provided on the adjusting support 412, and a corresponding locking part 421 is provided at one end of the upper roller shaft 42. This design provides a quick assembly and disassembly function. In actual use, when a hose connector needs to be passed, the operator can quickly release the upper roller shaft 42, and lock it again after the connector has passed, greatly improving work efficiency. The locking structure design also takes into account the anti-loosening requirements, ensuring a reliable locking effect even under high-intensity use conditions. At the same time, this structural design also facilitates daily maintenance and parts replacement.

[0060] In some embodiments, a guide roller 5 is also included, which is rotatably mounted on the base 1 and is used to guide the fire hose to the flattening mechanism 4.

[0061] In this invention, the guide roller 5 provides crucial auxiliary functionality to the entire winding system. In practical applications, it guides the water belt along the optimal path into the flattening mechanism 4, preventing skewing or twisting during entry. The rotation of the guide roller 5 significantly reduces frictional resistance during water belt transport, lowering system energy consumption. Furthermore, the guide roller 5 pre-shapes the water belt, improving the effectiveness of subsequent flattening and winding processes. The optimized placement of the guide roller 5 ensures a smooth water belt transport path and facilitates operator observation and control of the entire process.

[0062] The fire hose reel device uses a second insertion part 321 to engage with a first insertion part 311 to form a fixing part 33 for securing the end of the fire hose. The fixing part 33 secures the end of the fire hose. The drive mechanism 2 drives the fixed reeling fork 31 and the movable reeling fork 32 to rotate, thus completing the reeling of the fire hose. By separating the second insertion part 321 from the first insertion part 311, the coiled fire hose can be disassembled, making it convenient to pick up and put away the coiled fire hose and improving its reliability.

Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
