Description

Technical Field

[0001] This invention belongs to the field of fire protection equipment technology, and specifically relates to an improved fire hose reel device. Background Technology

[0002] Currently, the fire hose storage and reeling devices widely used in fire stations, enterprise fire stations, and fire trucks are mainly divided into two types: simple manual reels and fixed brackets / cabinets.

[0003] Simple manual hose reel: It usually consists of a central spool and two supporting structures on both sides. When reeling in the hose, the end of the hose needs to be fixed to the spool, and then the hose is manually wound around the spool multiple times. This device is simple in structure and inexpensive, but it relies entirely on the physical strength and skill of the operator. The winding efficiency is low, and it is difficult to ensure that the hose is flat and has consistent tension. Moreover, reeling in a wet hose is extremely physically demanding for firefighters.

[0004] While fixed supports / cabinets provide storage space for hoses, they typically only offer simple support functions. The hose coiling still requires manual operation and cannot achieve automation and standardization of the coiling process.

[0005] The aforementioned existing devices generally suffer from the following prominent problems in actual use:

[0006] Unstable winding quality can easily damage the hose: The tightness of manual winding is entirely controlled by human intervention. Loose winding can cause the hose to loosen during transportation, while tight winding will keep the hose in a high-stress state for a long time, accelerating the aging of the inner lining and fatigue of the braided layer, and may cause dead folds in the hose, reducing its pressure resistance and service life.

[0007] Low operational efficiency and delayed emergency response: Both winding and releasing the hoses rely on manual operation, which is time-consuming and labor-intensive, and cannot meet the timeliness requirements for rapid deployment and retrieval in firefighting operations.

[0008] Therefore, there is an urgent need to develop a new type of fire hose winding device that can achieve tight and orderly winding and storage of fire hoses while supporting one-button quick release and retrieval, thereby comprehensively improving the response efficiency, operational safety and fire hose maintenance level of fire fighting operations. Summary of the Invention

[0009] The purpose of this invention is to overcome the above-mentioned problems existing in the prior art and to provide an improved fire hose winding device.

[0010] Therefore, the above-mentioned objectives of the present invention are achieved through the following technical solutions:

[0012] frame,

[0013] A winding mechanism for winding fire hoses, comprising:

[0017] A spacing adjustment and locking mechanism is provided, through which the second take-up roller is movably mounted on the frame and has a locked state and a released state: in the locked state, the second take-up roller maintains a fixed spacing with the first take-up roller for hose winding; in the released state, the second take-up roller can move toward the first take-up roller to reduce the spacing, so as to facilitate the loading and unloading of the hose reel;

[0048] In this invention, the water hose is wound tightly, flatly, and with uniform tension by a precise guiding system consisting of an electric drive uniform speed winding and a limiting rod and adjustable roller. This fundamentally avoids structural damage to the water hose caused by improper manual operation, significantly extends the equipment life, ensures the absolute stability of the transportation and storage conditions, eliminates the safety hazards caused by scattering and knotting, and ensures the standardization of winding quality and equipment safety.

[0049] In this invention, the components are highly integrated, with the core components built into the main pipe and combined with the foldable swing arm mechanism, achieving compact storage and rapid deployment. It can be used flexibly as an independent unit with wheels or integrated into fire trucks, fully adapting to the needs of multiple scenarios and high mobility.

[0050] In this invention, operators only need to adjust the speed throttle to control the entire winding and unwinding process, completely liberating firefighters from heavy physical labor. This not only significantly reduces labor costs but also ensures that each winding operation meets the preset optimal standards, improving the overall automation level of fire equipment logistics maintenance and promoting the intelligent and labor-saving transformation of the operation mode.

[0051] This invention creatively integrates electric drive technology, an adjustable-gap mechanical locking mechanism, and a hose straightening and guiding system, systematically resolving the contradiction between "quick access" and "standardized winding" in traditional fire hose reeling devices. Based on stable power output provided by electric uniform-speed winding, the invention achieves one-button quick switching between "winding state" and "access state" through the coordinated operation of a pivotable locking gap adjuster and a latch-type quick-locking mechanism. Simultaneously, the guiding system, composed of a limit rod and adjustable rollers, ensures the smooth and orderly entry of the hose during winding, not only automating and standardizing the winding operation but also fundamentally overcoming the long-standing technical bottleneck of hose reels being "tightly wound but difficult to remove."

Detailed Implementation

[0066] The present invention will now be described in detail with reference to the embodiments and accompanying drawings.

[0067] An improved fire hose reel device of the present invention includes: a frame, the frame including a main pipe 2 and a wheel rod 1, the wheel rod 1 being fixedly connected to one end of the main pipe 2, and both ends of the wheel rod 1 being rotatably connected to movable wheels 10; the frame integrating a winding drive motor 14, a power supply 13, a control unit, and a speed control handle 4; the power supply 13 supplying power to the winding drive motor 14, the control unit, and the speed control handle 4; the speed control handle 4 being electrically connected to the control unit for inputting a winding speed control signal to the control unit; the control unit controlling the rotational speed and direction of the winding drive motor 14 according to the input signal;

[0068] The winding mechanism is connected to the output end of the winding drive motor 14 and is used to perform the winding and unwinding of the fire hose; the winding mechanism includes a fixed first winding roller 901 and a parallel second winding roller 902.

[0069] A spacing adjustment and locking mechanism is provided, through which the second take-up roller 902 is movably mounted on the main pipe 2, and has a locked state and a released state: in the locked state, the second take-up roller 902 maintains a fixed spacing with the first take-up roller 901 for hose winding; in the released state, the second take-up roller 902 can move toward the first take-up roller 901 to reduce the spacing, so as to facilitate the picking and putting of the hose reel.

[0070] A spacing adjustment and locking mechanism is provided, wherein the second take-up roller 902 is movably mounted on the main pipe 2 via the spacing adjustment and locking mechanism; the spacing adjustment and locking mechanism has a first winding position and a first pick-up and drop-off position: when in the first winding position, the spacing adjustment and locking mechanism locks the second take-up roller 902 at a position maintaining a first fixed spacing with the first take-up roller 901; when switching to the first pick-up and drop-off position, the second take-up roller 902 is released and can move relative to the first take-up roller 901 to reduce the spacing; and a hose guide mechanism is provided on the hose entry side of the winding mechanism, including a limiting rod 19 and a first adjustable roller 8; the limiting rod 19 is installed on one end of the main pipe 2 adjacent to the wheel rod 1, and is used to laterally limit the entry of the fire hose; the first adjustable roller 8 is rotatably connected to the wheel rod 1 and is located beside the main pipe 2, and is used to receive the hose guided by the limiting rod 19.

[0071] The spacing adjustment and locking mechanism includes: a fixed frame 1802, fixedly installed on the main pipe 2, and the first take-up roller 901 fixedly installed on the fixed frame 1802; a spacing adjuster 1805, one end of which is rotatably connected to the fixed frame 1802 via a pivot shaft, and the second take-up roller 902 is installed on the other end of the spacing adjuster 1805; and a locking assembly for selectively locking the spacing adjuster 1805 at the unfolded position corresponding to the first winding position.

[0072] The locking component includes:

[0073] The latch 1803 is fixedly mounted on the fixing frame 1802;

[0074] A lever 1806 is rotatably mounted on the spacing adjuster 1805, and the lever 1806 has a locking hole 1807 that matches the locking tenon 1803.

[0075] When the spacing adjuster 1805 is rotated to the unfolded position, rotating the lever 1806 can cause the latch 1803 to engage in the latch hole 1807 to achieve locking; rotating the lever 1806 in the opposite direction can cause the latch 1803 to disengage to release the lock.

[0076] The fixed frame 1802 has a slot 1801 corresponding to the position of the second take-up roller 902 when it is in the first winding position. When the spacing adjuster 1805 is in the unfolded position, the second take-up roller 902 is accommodated in the slot 1801.

[0077] It also includes a foldable swing arm mechanism, which comprises:

[0078] The first swing arm 3 is rotatably connected to the front side of the other end of the main pipe 2 via a support 12, and the speed control handle 4 is installed on the first swing arm 3.

[0079] The second swing arm 5 is rotatably connected to the lower side of the other end of the main pipe 2 via the support 12, and the end of the second swing arm 5 is rotatably connected to the second adjustable roller 7.

[0080] The first swing arm 3 and the second swing arm 5 are respectively locked in the unfolded or folded position by the pluggable first pin 6 and the second pin 11, and the second adjustable roller 7 cooperates with the first adjustable roller 8 to guide and pre-tighten the water belt.

[0081] The first adjustable roller 8 and the second adjustable roller 7 have the same structure, both including a roller rod 701, a first baffle 702 fixed to one end of the roller rod 701, and a second baffle 703 movably sleeved on the other end of the roller rod 701 and a positioning sleeve 705. A positioning nut 704 is welded to the outside of the positioning sleeve 705, and a positioning bolt 706 is threaded into the positioning nut 704 to adjust and lock the position of the second baffle 703 on the roller rod 701 to accommodate water hoses of different widths, thus enabling the invention to have a rapid adjustment function for winding water hoses of different specifications. The first baffle 702 and the second baffle 703 are both configured with guide slopes on the side closest to the center of the roller rod 701. These guide slopes provide a smooth transition when the water hose is introduced, effectively guiding the water hose to slide smoothly into the working area between the two baffles, avoiding jamming or obstruction caused by right angles at the edges, and further improving the smoothness and reliability of the operation.

[0082] The water hose guided by the limiting rod 19

[0083] The first swing arm 3 includes a first arm 301 and a handle 302 fixed to one end thereon. The speed control throttle 4 is mounted on the handle 302. The other end of the first arm 301 is provided with a connecting piece 303 with a rotating hole 305 and a first limiting insertion hole 304. The first pin 6 cooperates with the support 12 to achieve hinge and positioning.

[0084] The winding drive motor 14 is a speed-regulating motor, and its output end is connected to the winding mechanism through the drive shaft 903. The winding mechanism is specifically a rotating fork 9 equipped with the first take-up roller 901 and the second take-up roller 902.

[0085] The side wall of the main pipe 2 has a first mounting opening 201 for mounting the winding drive motor 14 and a second mounting opening 203 for mounting the power supply 13.

[0086] The device is configured as an independent operating unit that moves via the moving wheels 10, or it can be detachably installed in a fire truck to form a vehicle-mounted winding system.

[0087] The improved fire hose reel winding device of this invention has the following advantages: By innovatively adopting a mechanical structure that combines a pivotable locking spacing adjuster with a quick-locking mechanism using a latch lever, it effectively solves the technical problem of traditional fire hose reel winding devices where the fixed spacing of the winding rollers makes it difficult to quickly unload the hose after winding. During winding, the device can precisely position and rigidly lock the second winding roller, ensuring that the hose is wound neatly and tightly. When unloading, simply moving the lever releases the lock, causing the second winding roller to automatically move closer to the first winding roller. This allows the hose roll to loosen naturally due to the reduced inner ring support, enabling the entire roll of hose to be quickly and easily removed. Ultimately, it achieves the technical effect of one-button switching and efficient winding, significantly improving the efficiency and convenience of hose handling in firefighting operations.

[0088] An improved fire hose reeling device of the present invention utilizes electric drive technology, an adjustable spacing mechanical locking mechanism, and a regular guiding system to systematically solve the core contradiction of the traditional fire hose reeling device that cannot simultaneously achieve "quick access" and "standard winding", as well as a series of operational efficiency and equipment maintenance problems arising therefrom.

[0089] This invention, through its "adjustable spacing" design, enables rapid overall retrieval and placement of the hose reel, eliminating delays in critical operations. It solves the problems of low retrieval efficiency and delayed emergency response: traditional methods require laborious scooping or pulling from piled-up or jammed hoses.

[0090] This invention achieves smooth and consistent winding tension through an electric uniform-speed winding and guiding mechanism, greatly protecting the water hose and extending its service life. It solves the problem that winding quality relies entirely on manual labor, which easily damages the water hose: traditional manual winding results in inconsistent tension, easily leading to hose aging and kinking.

[0091] The water hose reel of this invention is neat and sturdy, and will not scatter during transportation. It can be quickly and smoothly unfolded and laid upon arrival at the site. It solves the problem of unstable storage conditions and safety hazards: traditional disorderly stacking easily leads to scattering and knotting during transportation.

[0092] This invention, through electric drive and handheld speed control, liberates personnel from heavy, repetitive manual labor, achieving labor-saving and standardized winding operations. It solves the problems of low automation and high labor costs: traditional methods rely entirely on manual labor, resulting in high labor intensity.

[0093] The present invention has the following beneficial effects:

[0094] Highly efficient, convenient, and responsive: The storage and retrieval of the hose reel can be completed within seconds, achieving "millisecond-level release," which greatly improves the emergency response speed and operational efficiency of the fire brigade.

[0095] Standardized winding and protective equipment: Produces tight, neat, and uniformly tight hose reels, avoiding physical damage to the hose structure caused by improper winding, and significantly improving the reliability and service life of fire hoses.

[0096] Stable operation and reliable safety: Whether in storage or transportation, the water hose always remains in a neat and orderly state, eliminating the risk of jamming caused by tangling or knotting, and improving operational safety.

[0097] Intelligent and labor-saving, standardized: The automated and speed-adjustable winding process reduces the physical burden and technical dependence of operators, ensuring that every winding meets high-standard operating procedures and improving the overall quality of logistics maintenance.

[0098] Multifunctional and highly adaptable: The device combines a mobile, independent operating unit with vehicle-mounted integration capabilities, flexibly adapting to the application needs of various scenarios such as fire stations, training grounds, and combat vehicles. Furthermore, the invention features a compact and efficient structural design. Its main frame is integrated onto the main pipe, with key components such as the drive motor, power supply, and control unit housed within the pipe body. Only the necessary foldable swing arms and winding rollers extend externally, resulting in a compact overall structure and simplified components. In non-operating mode, the first and second swing arms can be folded inwards and quickly locked with pins, significantly reducing the device's external profile and greatly improving storage convenience. Simultaneously, the device itself can be flexibly moved using wheels, eliminating the need for fixed installation. This not only facilitates storage and deployment in fire garages, training grounds, and other locations but also significantly reduces the space occupied by long-term storage, achieving high-density, tidy storage in limited spaces and fully meeting the stringent requirements of firefighting operations for equipment mobility and space utilization.

[0099] This invention, through technological innovation, transforms the logistical handling of fire hoses into a standardized process that is efficient, standardized, labor-saving, and intelligent. This fundamentally improves the combat readiness and deployment efficiency of firefighting equipment, and has significant practical value and promotional significance.

[0100] Example 1

[0101] like Figure 1-13 As shown, an improved fire hose reeling device of the present invention has a core frame consisting of a main pipe 2 and a wheel rod 1 vertically fixed to one end of it. The wheel rod 1 has casters 10 installed at both ends, allowing the entire device to move freely like a handcart, becoming an independent operating unit. The main pipe 2 is made of square or round tubing and is hollow inside for the integrated installation of key components.

[0102] The entire power and control system is integrated inside and on the sidewalls of the main pipe 2, including:

[0103] Winding drive motor 14: This is a speed-regulating motor with a reducer, which provides the core power for the winding operation. The winding drive motor 14 is fixed to the main pipe 2 by bolts.

[0104] Power source 13 is a high-capacity lithium battery pack that powers the entire system. It is inserted through the second mounting opening 203 on the main pipe 2 and connected to the main pipe 2 by the battery limiting slide plate 205 through the protrusion on the battery.

[0105] The control unit is installed inside the main pipe 2 and is electrically connected to the winding drive motor 14, the power supply 13 and the speed control throttle 4 respectively. It is responsible for receiving commands and controlling the operation of the motor.

[0106] Speed ​​control throttle 4: Installed at the end of the main pipe 2, the operator can steplessly adjust the winding speed by rotating the throttle and control the winding direction by moving the throttle.

[0107] The winding action is performed by a winding mechanism, the core of which is a rotating fork 9. The rotating fork 9 is directly connected to the drive shaft 903 of the drive motor 14 and can be driven by the motor to rotate at a constant speed. Two parallel take-up rollers are mounted on the rotating fork 9.

[0108] The first take-up roller 901 is directly and fixedly mounted on the rotating fork 9 or a fixed frame 1802 fixed thereto, and its position is fixed.

[0109] The second take-up roller 902 is mounted on the spacing adjuster 1805, which is rotatably mounted on the fixed frame 1802 via a rotating shaft 1808.

[0110] Fixed frame 1802: Fixedly installed on the main pipe 2, forming the base of the entire winding mechanism. It is provided with a slot 1801 and a fixed tenon 1803.

[0111] Spacing adjuster 1805: It functions similarly to a rocker arm, and its rotation realizes the displacement of the second take-up roller 902.

[0112] Locking assembly: consists of a rotatable lever 1806, on which a locking hole 1807 is provided.

[0113] In the winding state, locking: Swing the movable arm 1805 outwards so that the second take-up roller 902 falls into the slot 1801 of the fixed frame (at this time, the distance between the two rollers is at its maximum and fixed). Then, rotate the lever 1806 downwards so that the latch 1803 on the fixed frame is inserted into the latch hole 1807 of the lever. At this point, the movable arm is rigidly locked, and the position of the second take-up roller 902 is absolutely fixed, providing a stable and reliable working platform for winding.

[0114] Release during take-up and take-down: After winding is complete, rotate lever 1806 upwards to disengage latch 1803 from latch hole 1807. Once unlocked, gently pull movable arm 1805 inwards. The second take-up roller 902 moves out of the slot and approaches the first take-up roller 901, rapidly reducing the distance between the two rollers. See details. Figure 12 As shown, due to the sudden reduction in the inner ring support, the water tape reel, which was originally taut on the double rollers, immediately becomes loose, allowing the operator to easily remove it horizontally from the side. The process of loading an empty or wound water tape reel is the reverse.

[0115] To ensure the hose can be wound smoothly and evenly, a hose guide mechanism is installed on the inlet side of the winding mechanism.

[0116] The frame is also equipped with a hose guide mechanism, located on the hose entry side of the winding mechanism, to provide lateral restraint and initial guidance for the fire hose about to enter the winding. The hose guide mechanism includes a limiting rod 19 and a first adjustable roller 8. The limiting rod 19 provides lateral restraint to the fire hose when it is being wound, guiding the hose along a set path into the first adjustable roller 8, and then, after being guided by the first adjustable roller 8, it is neatly conveyed to the winding mechanism. The limiting rod 19 is slightly higher than the first adjustable roller 8. The first adjustable roller 8 and the limiting rod 19 work together to separate and flatten the hose in the vertical direction, thereby conveying it more neatly to the winding mechanism and ensuring neat winding.

[0117] Limiting rod 19: Vertically installed at one end of the main pipe 2 near the wheel rod 1. Its main function is to laterally limit the water hose in motion and separate the water hose into two strands. One strand is limited above the limiting rod 19 and then passes through the lower side of the first adjustable roller 8 near the limiting rod 19 to merge with the other strand that passes directly below the first adjustable roller 8 before winding together at the rotating fork 9, thus achieving unidirectional double winding of the fire hose.

[0118] The first adjustable roller 8 is horizontally rotatably connected to the wheel rod 1 and located beside the main pipe 2. Its roller surface is slightly lower than the top of the limiting rod 19. The water belt first passes through the lateral constraint of the limiting rod 19, and then is lifted and guided into the first adjustable roller 8.

[0119] The second adjustable roller 7 is installed at the end of the foldable second swing arm 5. After the second swing arm 5 is unfolded, the second adjustable roller 7 and the first adjustable roller 8 are spatially staggered and separated vertically, forming an "S"-shaped or "vertically separated" guide channel. This channel can flatten and smooth the flat hose and apply appropriate pre-tension, allowing it to enter between the two take-up rollers in the best posture, achieving bidirectional double-winding of the fire hose, which is the key to achieving neat winding.

[0120] The first adjustable roller 8 and the second adjustable roller 7 have the same structure, with a roller rod 701 as their core. A first baffle 702 is fixed at one end, and a second baffle 703 at the other end is movably connected via a positioning sleeve 705. A positioning nut 704 is welded onto the positioning sleeve 705. Tightening the positioning bolt 706 can push the second baffle 703 to move on the roller rod, thereby adjusting the width between the two baffles to perfectly fit fire hoses of different diameters.

[0121] The limiting rod 19 includes a horizontal rod 1903. The horizontal rod 1903 is provided with a set of parallel first guide rods 1901 and second guide rods 1902. The second guide rod 1902 is provided with a sliding sleeve and is fixed in position by positioning bolts. The limiting distance can be adjusted according to the width of the fire hose to adapt to fire hoses of different diameters and prevent the hose from shifting during winding or transportation.

[0122] The frame includes a main pipe and wheel rods. The wheel rods are fixedly connected to one end of the main pipe, and movable wheels are provided at both ends.

[0131] When both swing arms are folded and locked with pins, the external profile of the device becomes very compact, saving a great deal of storage space.

[0132] The main pipe 2 is also hinged with a foldable swing arm mechanism, which includes a first swing arm and a second swing arm. The first swing arm is provided with the speed control handle, and the end of the second swing arm is rotatably connected to an auxiliary guide roller.

[0141] The improved fire hose reel device of the present invention includes a pitch-adjustable winding device for rapid storage and retrieval of fire hoses, comprising a rotating fork 9, a positioning frame 18, and a locking structure 16.

[0142] The rotating fork 9 is equipped with at least a first take-up roller 901 and a second take-up roller 902. After the rotating fork 9 is driven to rotate, the fire hose is wound around the first take-up roller 901 and the second take-up roller 902, and the outer ring of the two take-up rollers.

[0143] The rotating fork 9 includes a drive shaft 903, and a winding drive motor 14 is provided at one end of the drive shaft 903. The winding drive motor is a speed-regulating motor, and can be a hollow geared motor or a worm gear reducer motor.

[0144] A positioning frame 18 is provided, and a drive shaft 903 is rotatably mounted on the positioning frame 18.

[0145] The positioning frame 18 includes a fixed frame 1802, a slot 1801, a tenon 1803, and a receiving groove 1804. The fixed frame 1802 has a slot 1801 for securing the second take-up roller 902 on the positioning frame 18, and a tenon 1803 for engaging a locking structure 16, which locks the second take-up roller 901 on the positioning frame 18. A spacing adjuster 1805 is rotatably mounted on the fixed frame 1802 and placed within the receiving groove 1804. The second take-up roller 901 is pivotally mounted on the fixed frame 1802 via the spacing adjuster 1805.

[0146] The spacing adjuster 1805 is equipped with a locking structure 1806.

[0147] The locking structure 1806 is a lever with a mounting hole 1807 on it, which is rotatably mounted on the spacing adjuster 1805 and locked to the fixing frame 1802 by a latch 1803.

[0148] The drive shaft 903 is rotatably mounted on the fixed frame 1802, and the first take-up roller 901 is fixedly mounted on the fixed frame 1802;

[0149] Rotate the spacing adjuster 1805 to drive the second take-up roller 902 into the slot 1801, clamp the second take-up roller 902 in the slot 1801, move the lever to insert the tenon 1803 into the mounting hole 1807, lock it in place through the locking structure, and fix the position of the two take-up rollers to achieve smooth winding of the fire hose and ensure that the hose will not deviate when winding.

[0150] After the fire hose is wound up, move the lever to disengage the latch 1803 from the mounting hole 1807, unlocking the spacing adjuster 1805. After rotating the spacing adjuster 1805 on the fixed frame 1802, the first winding roller 901 gradually reduces the distance between itself and the second winding roller 902, making it easier for the fire hose to come off the two winding rollers.

[0151] Working principle: This invention achieves automatic winding through electric drive and solves the contradiction between "neat winding" and "rapid retrieval" in traditional devices through a unique adjustable-pitch winding mechanism. During operation, the device is in "winding state"; during retrieval, it can quickly switch to "retrieval state", realizing a seamless transition from efficient and neat winding to second-level overall storage and retrieval.

[0152] In electric winding mode, the device is first fixed at the "first winding position" by its spacing adjustment and locking mechanism. At this time, a stable working distance is maintained between the parallel first and second take-up rollers. The operator passes the loose hose end through the neat guide channel formed by the limit rod and the first adjustable roller, and guides it through the second adjustable roller on the deployable second swing arm, embedding it between the two take-up rollers. Subsequently, the operator issues a command through the speed control handle, and the control unit drives the angle-regulating speed motor to run, which drives the rotating fork to rotate at a uniform speed through the drive shaft. During this process, the hose is continuously and smoothly wound around the two take-up rollers. The limit rod and adjustable roller system effectively prevents the hose from deviating and piling up, ensuring tight winding and neat layering. The entire winding process does not require manual traction, and the winding speed and tension can be flexibly controlled through the throttle, ultimately forming a neat and solid hose reel.

[0153] When it's necessary to remove and store the finished tape reel or install a new one, the device can instantly switch to the rapid tape reel loading / unloading state. The key to this process lies in the operation of the spacing adjustment and locking mechanism: simply reverse the lever on the spacing adjuster to disengage the latch on the fixing frame from the lever's locking hole, thus releasing the lock on the spacing adjuster. Then, gently pull the spacing adjuster inward; the second take-up roller at its end moves out of the positioning slot on the fixing frame and moves towards the first take-up roller, rapidly reducing the distance between the two rollers. The device then enters the "first loading / unloading position." At this point, due to the reduced support spacing, the tape reel, which was originally taut on the roller, immediately loosens, allowing the operator to easily remove it horizontally from the side—the entire process is smooth and unobstructed. Conversely, when loading a pre-wound tape reel, first place the device in the loading / unloading position (small spacing state), insert the tape reel, then pull the spacing adjuster outward to the slot position and rotate the lever to re-lock it. The device then returns to the winding state and is ready to go.

[0154] This invention provides an improved fire hose reel device. In use, the device is pushed to the work point, the first and second swing arms are unfolded and locked, and the spacing of the adjustable roller baffles is adjusted according to the hose width. The spacing adjustment mechanism is locked in the "winding state." The loose or used hose, awaiting tidying, is passed through the limiting rod, guided through the guide channel formed by the first and second adjustable rollers, and introduced between the locked first and second take-up rollers. The device is started, and the winding drive motor is controlled by the speed control lever, automatically, uniformly, and smoothly winding the hose into a reel. After winding, the device is stopped. The lever is moved to unlock, and the adjuster is rotated inward to bring the two take-up rollers together. The hose reel loosens due to the inner coil contraction and can be easily removed as a whole and transferred to a storage rack or used directly. After operation, the two swing arms are folded and locked, and the device can be pushed into a parking space or a corner of the warehouse for storage.

[0155] This invention integrates the winding, storage, and retrieval of fire hoses into an efficient, standardized, and labor-saving closed-loop process through mechatronics design and ingenious mechanical linkage. It fundamentally solves the inherent problems of laborious winding, chaotic storage, and slow retrieval in traditional methods, and significantly improves the logistical support efficiency and emergency response speed of fire fighting operations.

[0156] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
