Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0053] The following is combined Figures 1-15 This utility model describes a multi-functional fire truck.

[0054] An embodiment of this utility model proposes a multi-functional fire truck, such as... Figures 1 to 7 As shown, the multi-functional fire truck includes a transport body 20, a pressurization system 40, a tailgate assembly 30, and a fire robot 50.

[0055] The transport body 20 has a storage space 23; the pressurization system 40 is located in the storage space 23; the tail plate assembly 30 includes a tail plate component 31 and a drive component 32, the tail plate component 31 is movably connected to the transport body 20, the drive component 32 is installed on the transport body 20, and the drive component 32 is used to drive the tail plate component 31 to switch between a suspended state and an inclined state; the fire-fighting robot 50 includes a walking mechanism 51, a delivery pipe and a working pump 53, the working pump 53 is detachably installed on the walking mechanism 51, the working pump 53 is detachably connected to one end of the delivery pipe, and the other end of the delivery pipe is connected to the pressurization system 40; the tail plate component 31 is in an inclined state, and the walking mechanism 51 is adapted to walk on the tail plate component 31 to move away from or close to the transport body 20.

[0056] It is understood that the tail plate component 31 is movably connected to the transport body 20 and is driven to rotate relative to the transport body 20 by the drive component 32, thereby switching between a suspended state and an inclined state. In the suspended state, the tail plate component 31 is at a certain distance from the ground and is approximately parallel to the ground. At this time, the tail plate component 31 serves as a carrying platform for transporting the fire-fighting robot 50, bearing the heavy weight of the fire-fighting robot 50. In the inclined state, the tail plate component 31 is abutting against the ground at a certain angle, that is, the tail plate component 31 is inclined downward on the transport body 20. The walking mechanism 51 of the fire-fighting robot 50 is adapted to walk on the tail plate component 31 to move away from or towards the transport body 20. At this time, the tail plate component 31 is used for loading and unloading the fire-fighting robot 50.

[0057] The working pump 53 is detachably installed on the traveling mechanism 51, allowing the working pump 53 on the traveling mechanism 51 to be replaced according to the needs of firefighting operations, thus enabling different firefighting operations. For example, when the working pump 53 on the traveling mechanism 51 is a drainage pump, it draws water from a natural water source to provide a water source for the fire truck, and the water is pressurized and delivered to the site via the booster system 40, so that the firefighting robot 50 can be used for firefighting operations; when the working pump 53 on the traveling mechanism 51 is a sewage pump, it performs urban drainage, and the sewage is discharged via the booster system 40, so that the firefighting robot 50 can be used for urban drainage operations. Thus, the firefighting robot 50 can be used for both firefighting and urban drainage operations.

[0058] The multi-functional fire truck provided in this embodiment of the utility model has a working pump 53 that can be detachably installed on the walking mechanism 51. Different working pumps 53 can be replaced according to the needs of fire fighting operations. When the tail plate component 31 is in an inclined state, the fire robot 50 drives to the water source or drainage area to achieve multiple operations, thereby realizing one vehicle for multiple uses, reducing the occupation of resources and manual assistance, and thus reducing equipment and labor costs.

[0059] In one embodiment of the present invention, the working pump 53 includes a drainage pump and a sewage pump, one of which is detachably mounted on the walking mechanism 51, and the other of which is placed in the storage space 23.

[0060] It is understood that the walking mechanism 51 has a mounting position where one of the drainage pump and the sewage pump can be installed, and the other of the drainage pump and the sewage pump is placed in the storage space 23 of the transport body 20. Thus, the multi-functional fire truck in this embodiment is equipped with a drainage pump and a sewage pump. According to the needs of fire fighting operations, a drainage pump or a sewage pump can be installed at the mounting position of the walking mechanism 51 to realize fire fighting operations and urban drainage operations.

[0061] For example, a drainage pump is installed on the walking mechanism 51. The drainage pump is connected to one end of a delivery pipe, and the other end of the delivery pipe is connected to a pressurization system 40. The delivery pipe has a certain length. In the event of a fire, the tail plate component 31 is first driven by the drive component 32 to switch from a suspended state to an inclined state. The fire-fighting robot 50 is then detached and driven to the water source. At this time, the drainage pump carried by the fire-fighting robot 50 is placed in the water to start drawing water. The pressurization system 40 pressurizes the water, increasing the water pressure so that the water can flow to the distant fire source.

[0062] It should be noted that traditional fire-fighting equipment is only equipped with one type of drainage pump. Since urban drainage is generally sewage with many impurities, normal drainage pumps require relatively clean water sources. If drainage pumps are used for urban drainage, the sewage with many impurities can easily cause the drainage pumps to get stuck or damaged, thus affecting the normal operation of fire-fighting equipment. Therefore, traditional fire-fighting equipment has a single operation. In contrast, the multi-functional fire truck in this embodiment is equipped with both drainage pumps and sewage pumps. Depending on the needs of fire-fighting operations, drainage pumps or sewage pumps can be installed at the mounting position of the walking mechanism, achieving multiple uses for one vehicle. It can be applied to fire scenarios such as factories, highways, large chemical plant parks, forests, and grasslands, as well as various rescue scenarios such as drought relief, flood drainage, and emergency rescue.

[0063] Furthermore, one end of the delivery pipe is connected to a quick-release connector, which is used to connect to the working pump 53, thereby enabling quick replacement of different working pumps 53.

[0064] In one embodiment of this utility model, such as Figure 4 As shown, the traveling mechanism 51 has a mounting platform 52 with mounting positions. A tape reel 55 is mounted on the mounting platform 52. The conveying pipe is a flexible hose wound around the tape reel 55, and both ends of the conveying pipe are connected to the booster system 40 and the working pump 53, respectively. It should be noted that during the travel of the traveling mechanism 51, the tape reel 55 rotates synchronously, so that the conveying pipe is simultaneously laid or wound between the transport body 20 and the traveling mechanism 51.

[0065] Optionally, the fire-fighting robot 50 also includes a crane 54 mounted on a platform 52, which is used to place the working pump 53 on the water surface to collect water.

[0066] The crane 54 can also be used to replace the working pump 53 on the traveling mechanism 51. Taking the installation of a drainage pump on the traveling mechanism 51 as an example, the traveling mechanism 51 moves to the storage space side of the transport body 20, and the crane 54 moves the drainage pump on the mounting platform 52 to the storage space 23 of the transport body 20, and then moves the sewage pump in the storage space 23 to the installation position on the mounting platform 52. It should be noted that when the storage space is limited, the drainage pump originally installed on the traveling mechanism 51 can be placed on the ground first using the crane 54, and after the sewage pump is moved to the installation position on the mounting platform 52, the drainage pump placed on the ground can be lifted into the storage space 23 using the crane 54.

[0067] Furthermore, the crane 54 can be installed on the mounting platform 52 by means of an adjustment device. The adjustment device may include a lifting mechanism, a rotating mechanism, or both, to enable the lifting and rotating of the crane 54, facilitating the movement of the working pump 53 between the storage space 23 and the mounting platform 52.

[0068] In one embodiment of this utility model, such as Figure 4 As shown, the working pump 53 includes a frame 531 and a pump body 532 disposed within the frame 531. The mounting position is a mounting slot opened on the mounting platform 52, and the frame 531 is used to place the pump body 532 on the top. A lifting ring is provided on the top of the pump body 532.

[0069] In this embodiment, a connecting plate located outside the mounting slot is provided on the mounting platform 52. A first connecting hole is provided on the connecting plate, and a second connecting hole corresponding to the first connecting hole is provided on the frame 531. The first connecting hole and the second connecting hole are connected by a connector 334 to realize the installation of the working pump 53 on the mounting platform 52.

[0070] In one embodiment of this utility model, the walking mechanism 51 includes a walking component and a walking drive component. The walking drive component drives the walking component to move in order to achieve walking movement. For example, the fire-fighting robot 50 is a tracked fire-fighting robot, and the walking component is a tracked walking component.

[0071] Optionally, the tail plate component 31 has a receiving cavity for accommodating the walking component; when the tail plate component 31 is suspended, the walking component is confined to the receiving cavity of the tail plate component 31 to position the walking component, thereby realizing the positioning of the fire-fighting robot 50 and thus avoiding the shaking of the fire-fighting robot 50 during transportation.

[0072] Furthermore, the walking mechanism 51 has a positioning groove, and the tail plate component 31 has a positioning member that cooperates with the positioning groove. The positioning member is adapted to switch between a first position and a second position. In the suspended state, the positioning member extends into the positioning groove and is in the first position. In the tilted state, the positioning member leaves the positioning groove and is in the second position.

[0073] Understandably, when the tail plate component 31 is suspended, the fire-fighting robot 50 is mounted on the tail plate component 31. The position of the walking component of the fire-fighting robot 50 is positioned by the receiving cavity of the tail plate component 31, and the positioning component is driven to extend and enter the positioning groove of the walking mechanism 51 by the telescopic drive component to lock the position of the fire-fighting robot 50. At this time, the positioning component is in the first position. When the fire-fighting robot 50 is working, the positioning component is driven to retract by the telescopic drive component, and the positioning component leaves the positioning groove to release the lock on the position of the fire-fighting robot 50. At this time, the positioning component is in the second position.

[0074] In other embodiments, the transport body 20 may be provided with clamping components to clamp the fire-fighting robot 50 on the tail plate component 31, thereby fixing the fire-fighting robot 50.

[0075] like Figure 1 and Figure 5As shown, the transport body 20 includes a chassis 21 and a carriage 22. The carriage 22 is disposed on the chassis 21, and a storage space 23 is formed on the carriage 22. The tail panel assembly 30 is rotatably connected to the rear of the chassis 21.

[0076] like Figure 5 and Figure 6 As shown, the tail plate component 31 has a rectangular structure. The tail plate component 31 is hinged to the chassis 21 through hinges such as pivots and pins, and is located at the rear of the chassis 21. The tail plate component 31 is used to load and unload firefighting robots or to bear the heavy weight of firefighting robots, serving as a carrying platform for transporting firefighting robots.

[0077] Optionally, the tailgate assembly 30 also includes a locking component 33, which includes a locking drive 331 and a locking component 332. The locking component 332 is rotatably connected to the chassis 21 and connected to the locking drive 331. The locking drive 331 is mounted to the chassis 21 and is adapted to drive the locking component 332 to switch between a locked state and an unlocked state. In the locked state, the locking component 332 is hooked onto the tailgate assembly 31, keeping the tailgate assembly 31 in a suspended state. In the unlocked state, the locking component 332 is disengaged from the tailgate assembly 31.

[0078] The drive component 32 can be a hydraulic cylinder, a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. The locking drive component 331 is vertically fixed to the middle of the main beam of the chassis 21 by a fixing component. The locking drive component 331 is controlled to move up and down by a hydraulic directional valve to lock and open the tailgate body 311.

[0079] Since the driving component 32 that drives the tailgate component 31 to move is also a hydraulic cylinder, the multi-functional fire truck itself is equipped with a hydraulic power source. By adding a hydraulic pipeline between the original hydraulic power source and the locking drive component 331, the locking drive component 331 can be controlled, thereby driving the locking component 332 to switch between the locked and unlocked states. The method is simple and highly practical.

[0080] It is understood that in this embodiment, the tailgate assembly 30 is equipped with a locking component 33 on the chassis 21, such that the locking component 33 includes a locking drive component 331 and a locking component 332. The locking component 332 is connected to the output end of the locking drive component 331. The locking drive component 331 is adapted to drive the locking component 332 to switch between a locked state and an unlocked state. In the locked state, the locking component 332 is hooked onto the tailgate assembly 31, so that the tailgate assembly 31 is kept in a suspended state. In the unlocked state, the locking component 332 is disengaged from the tailgate assembly 31.

[0081] With this configuration, when the tailgate assembly 31 is in a suspended state, the locking drive component 331 drives the locking component 332 to hook onto the tailgate assembly 31. At this time, the locking component 332 restrains the tailgate assembly 31, which can compensate for internal leakage of the drive component 32 within a specified range, causing the tailgate assembly 30 to tilt or descend, thereby improving the safety of transporting the multi-functional fire truck. Essentially, when the tailgate assembly 31 is in a suspended state, it is not only locked by the drive component 32, but also mechanically locked by the locking component 332, thus improving the reliability of the tailgate assembly 30 locking. When the tailgate assembly 31 is in a tilted state, the locking drive component 331 drives the locking component 332 to disengage from the tailgate assembly 31. At this time, the drive component 32 can drive the tailgate assembly 31 to rise and fall freely.

[0082] See Figure 7 and Figure 8 In some embodiments of this utility model, the locking member 332 has a rod-shaped structure and includes a locking body 3321 of a certain length. A hinge portion 3322 is provided at one end of the locking body 3321. The width of the hinge portion 3322 is greater than the width of the locking body 3321, which can improve the reliability of the connection of the locking member 332. The hinge portion 3322 is rotatably connected to the chassis 21 by a pin. A hook portion 3323 is formed at the other end of the locking body 3321. The hook portion 3323 can hook onto the tail plate component 31 in the locked state, so that the tail plate component 31 is kept in the suspended state.

[0083] The locking element 332 is preferably integrally formed. For ease of explanation, the locking element 332 is divided into a locking body 3321, a hinge part 3322, and a hook part 3323.

[0084] Continue reading Figure 7 and Figure 8 The tailplate component 31 includes a tailplate body 311 and a hinge seat 312. The tailplate body 311 is hinged to the chassis 21 via a hinge. The hinge seat 312 is welded or detachably connected to the hinge side of the tailplate body 311 via bolts or other structures. The hinge seat 312 is angled relative to the tailplate body 311, i.e., the hinge seat 312 is inclined relative to the tailplate body 311. A hinge hole is provided transversely along the upper edge of the hinge seat 312, and a pin (not labeled in the figure) passes through the hinge hole. The driving end of the drive component 32 cooperates with the pin.

[0085] When the piston rod of the drive component 32 extends, the drive component 32 pushes the pin to drive the hinge seat 312 to move in a straight line, so that the tail plate body 311 rotates around the hinge point with the chassis 21, and the tail plate body 311 switches from the suspended state to the tilted state.

[0086] When the piston rod of the drive component 32 retracts, the drive component 32 pulls the pin shaft to drive the hinge seat 312 to move in a straight line, so that the tail plate body 311 rotates around the hinge point with the chassis 21, and the tail plate body 311 switches from the tilted state to the suspended state.

[0087] The hook portion 3323 bends downward relative to the locking body 3321, and a slot 3324 is formed between the hook portion 3323 and the locking body 3321. When the locking member 332 is in the locked state, the slot 3324 is engaged with the pin.

[0088] To ensure the stability of the locking component 332, the height of the hook portion 3323 is greater than the sum of the height of the locking body and the radius of the pin. This is equivalent to the slot 3324 encircling the outside of the pin, and the anti-rotation pin disengaging from the slot 3324, thus improving the reliability of the locking component 332.

[0089] The movement process of the tailgate assembly 30 provided in this embodiment is as follows:

[0090] When the tailplate body 311 is in an inclined state, it is equivalent to the tailplate component 31 abutting against the ground at a certain angle. That is, the tailplate component 31 is inclined at the rear of the chassis 21. At this time, the tailplate component 31 is used to load and unload the fire-fighting robot. The locking component 332 is in the unlocked state, and the locking drive component 331 is in the extended state.

[0091] When the tailplate body 311 is in the suspended state, it is equivalent to the tailplate body 311 rising to the locked position. The tailplate body 311 is a certain distance from the ground and is approximately parallel to the ground. The tailplate body 311 serves as the carrying platform for transporting the fire-fighting robot, bearing the robot's heavy weight. At this time, the locking drive component 331 retracts, and the locking component 332 engages with the pin on the hinge seat 312 to achieve locking.

[0092] When the tailgate body 311 is about to fall, the drive component 32 needs to retract slightly to create a gap between the pin and the locking member 332. At this time, the locking drive component 331 extends, causing the locking member 332 to disengage from the pin and unlock. Then, when the piston rod of the drive component 32 extends, it pushes the pin to drive the hinge seat 312 to move linearly, causing the tailgate body 311 to rotate around the hinge point with the chassis 21, switching from a suspended state to a tilted state.

[0093] When the tailgate body 311 is raised to the suspended state, the locking drive 331 retracts and the locking component 332 descends to lock.

[0094] It is understood that the tailgate assembly 30 of this utility model uses the locking component 33 to ensure that the tailgate body 311 remains locked after being raised, so that the tailgate body 311 can be maintained in the raised position. That is, the locking component 33 keeps the tailgate body 311 in the suspended position and prevents it from falling, so that the tailgate body 311 is not affected by the load and the tailgate falling due to normal leakage of the hydraulic cylinder, which can improve the safety of the multi-functional fire truck.

[0095] like Figure 1 and Figure 3 As shown, the transport body 20 also includes a hose storage space 24 for storing hoses. The multi-functional fire truck also includes a hose reeling device 10 mounted on the transport body 20 for reeling in and out hoses. Specifically, the cargo compartment 22 includes a front compartment and a rear compartment. The front compartment has a storage space 23. The pressurization system uses a booster pump, which is located in the front compartment. The booster pump pressurizes the water intake through the chassis's full-power power take-off to achieve long-distance delivery. The rear compartment forms the hose storage space 24 and is welded from high-strength carbon steel, making it resistant to torsion and not easily deformed.

[0096] Furthermore, the multi-functional fire truck also includes a hose handling mechanism 60 installed on the vehicle body 22. The hose handling mechanism 60 is located above the hose storage space 24. A transmission component is provided between the hose reeling device 10 and the hose handling mechanism 60. The transmission component can be a chain drive. During the transportation of the hose, the transmission component drives the hose reeling device 10 to move back and forth in the horizontal direction relative to the hose handling mechanism 60, so that the hose is folded and placed in the hose storage space 24 or the hose folded and placed in the hose storage space 24 is transported out.

[0097] like Figures 9 to 15 As shown, the hose reeling and unloading device 10 includes a hose transport mechanism 100 and a hose guiding mechanism 200; the hose guiding mechanism 200 includes a hose guiding component 210 and a guiding drive component 220.

[0098] The hose guide assembly 210 is located at the input end of the hose transport mechanism 100. The hose guide assembly 210 contacts the hose to guide it to the hose transport mechanism 100. The hose guide assembly 210 rotates with the hose transport mechanism 100 about the width of the hose. A guide drive assembly 220 is mounted at one end to the hose transport mechanism 100 and connected to the hose guide assembly 210 at the other end. The guide drive assembly 220 drives the hose guide assembly 210 to rotate about the width of the hose, causing the hose guide assembly 210 to contact the hose.

[0099] In this embodiment, by providing a hose guide assembly 210 at the input end of the hose transport mechanism 100, the hose can be guided to the hose transport mechanism 100. By rotating the hose guide assembly 210 in conjunction with the hose transport mechanism 100 around the width of the hose, and by providing a guide drive assembly 220, the hose guide assembly 210 can be driven to rotate relative to the hose transport mechanism 100 around the width of the hose, causing the hose guide assembly 210 to contact the hose. This ensures that the hose guide assembly 210 can always guide the hose during transport, preventing hose deviation, preventing friction on the hose sidewalls, preventing hose stretching, improving the hose's service life, and solving the problem of hose deviation during hose recovery in the prior art.

[0100] like Figure 9 and Figure 11 As shown, in some embodiments, the hose transport mechanism 100 includes two support components 110 and a hose transport component 120.

[0101] Two support components 110 are arranged at intervals along the width direction of the hose; a hose guide component 210 is located between the two support components 110 and is rotatably engaged with the support components 110 about the width direction of the hose. A hose transport component 120 is located between the two support components 110 and is rotatably engaged with the two support components 110 about the width direction of the hose; the hose transport component 120 is located on one side of the hose guide component 210 and is used to transport the hose discharged from the hose guide component 210.

[0102] In this embodiment, by providing support components 110, an installation base can be provided for the hose transport component 120 and other components such as the hose guiding mechanism 200, while also providing support for the entire device. The two support components 110 are arranged at intervals along the width of the hose, with the hose guiding component 210 and the hose transport component 120 located between them. This layout makes the entire device more compact and saves space. The hose transport component 120 enables the transport of the hose to the storage station.

[0103] Furthermore, the hose transport mechanism 100 also includes two connecting components 130; the two connecting components 130 are spaced apart along the length of the hose; both ends of the connecting components 130 are respectively connected to two support components 110 to form a support frame, which can improve the support stability. Specifically, the connecting component 130 includes a connecting crossbar.

[0104] like Figures 13 to 15As shown, the hose transport assembly 120 further includes a belt conveyor 121 and a belt drive; the belt drive and support assembly 110 rotate about the width of the hose, thereby driving the belt conveyor 121 to transport the hose. The belt drive includes a hydraulic cylinder, which is connected to the hydraulic system of the multi-functional fire truck. This improves transport stability, and using the hydraulic system of the multi-functional fire truck to control the belt drive reduces costs. The hose is transported via the belt conveyor 121, ensuring a stable transport process.

[0105] like Figures 13 to 15 As shown, exemplarily, the conveyor belt 121 includes a conveyor belt 1211, a drive pulley 1212, and a driven pulley 1213. The two ends of the drive pulley 1212 are respectively rotatably engaged with two support components 110 around the width direction of the water belt, and at least one end of the drive pulley 1212 is connected to a belt drive member. The two ends of the driven pulley 1213 are respectively rotatably engaged with two support components 110 around the width direction of the water belt. The drive pulley 1212 and the driven pulley 1213 are arranged at intervals along the length direction of the water belt, and the conveyor belt 1211 is sleeved on the drive pulley 1212 and the driven pulley 1213. A water belt guide assembly 210 is disposed at one end of the conveyor belt 1211, and the water belt guide assembly 210 guides the water belt to the conveyor belt 1211.

[0106] like Figure 10 As shown, in some embodiments, the hose guiding assembly 210 includes a first guide member 211 and a first guide roller 212. The first guide member 211 is located at the input end of the hose transport mechanism 100; the first guide member 211 is rotatably engaged with the hose transport mechanism 100 about the width direction of the hose; the first guide member 211 is connected to the other end of the guide drive assembly 220. The first guide roller 212 is rotatably engaged with the first guide member 211 about the width direction of the hose, and the first guide roller 212 is used to contact the hose.

[0107] In this embodiment, by providing the first guide member 211, a mounting base can be provided for the first guide roller 212, and the water hose output from the first guide roller 212 can be guided to the water hose transport mechanism 100, preventing the water hose from deviating during transportation. The contact between the first guide roller 212 and the water hose further ensures the stability and smoothness of the water hose during transportation, thereby improving transportation efficiency. It also avoids the problem of excessive stretching of the water hose, extending its service life. The first guide roller 212 uses a rolling contact method, which, compared to sliding contact, can more effectively reduce wear and damage to the water hose. The design of the guide assembly can adapt to water hoses of different widths and thicknesses, exhibiting wide applicability.

[0108] Furthermore, along the length of the hose, the first guide member 211 has a guide groove 2111 for accommodating the hose; the first guide member 211 rotates with the hose transport mechanism 100 about the width of the hose. The design of the guide groove 2111 allows the hose to be transported along a predetermined path, avoiding deviation and confusion during transport. The guide groove 2111 provides a safe transport channel for the hose, reducing friction and collisions between the hose and surrounding objects, thereby extending the service life of the hose.

[0109] Specifically, the two sides of the first guide member 211 are respectively connected to the two support components 110 via pins to rotate around the width of the hose. The guide drive component 220 is located below the hose transport component 120. The mounting end of the guide drive component 220 is installed on the support component 110, and the driving end is connected to the first guide member 211 to drive the first guide member 211, thereby causing the first guide roller 212 to rotate up and down.

[0110] like Figure 12 As shown, the guide drive assembly 220 further includes a hydraulic cylinder for communication with the hydraulic system circuit of the multi-functional fire truck. The hydraulic cylinder uses high-pressure hydraulic fluid provided by the hydraulic system as its power source, enabling rapid, smooth, and powerful power transmission. This efficient energy conversion and transmission method allows the multi-functional fire truck to respond quickly during missions, improving rescue efficiency.

[0111] like Figure 10 As shown, the first guide member 211 further includes two guide baffles 2112; the two guide baffles 2112 are spaced apart along the width direction of the hose and are rotatably engaged with the hose conveying mechanism 100; the first guide roller 212 is located between the two guide baffles 2112 and is rotatably engaged with the two guide baffles 2112. Specifically, the guide baffles 2112 correspond one-to-one with the two support components 110, and the guide baffles 2112 are rotatably engaged with the support components 110 via pins; the first guide roller 212 is located between the two guide baffles 2112, and the first guide roller 212 and the two guide baffles 2112 enclose a guide groove 2111. The two ends of the first guide roller 212 are rotatably engaged with the two guide baffles 2112 respectively. When the hydraulic cylinder drives the two guide baffles 2112 to rotate upward or downward relative to the support assembly 110 with the pin as the pivot, the two guide baffles 2112 drive the first guide roller 212 to rotate synchronously, so that the first guide roller 212 is always in contact with the water hose, avoiding the problem of the water hose being overstretched, and extending the service life of the water hose.

[0112] Furthermore, the first guide member 211 also includes a connecting plate 2113; the two sides of the connecting plate 2113 are respectively connected to two guide baffles 2112, and the first guide roller 212 is located at the end of the connecting plate 2113 away from the water hose transport assembly 120, and rotates in cooperation with the guide baffle 2112.

[0113] Furthermore, the hose guiding assembly 210 also includes a limiting member; the limiting member is located at the opening of the guide groove 2111 and is connected to the first guide member 211; the limiting member is used to limit the hose within the guide groove 2111. During the hose retrieval process, if the hose is overstretched, the limiting member presses the hose against the guide groove 2111, which can offset part of the hose tension and improve the service life of the hose.

[0114] In some other embodiments, the hose guiding assembly 210 includes a second guide member; the second guide member is located at the input end of the hose transport mechanism 100 and rotatably engages with the hose transport mechanism 100; the second guide member contacts the hose and guides the hose to the hose transport mechanism 100. The guide drive assembly 220 drives the second guide member to rotate relative to the hose transport mechanism 100, ensuring that the second guide member is always in contact with the hose. The position of the second guide member can be adjusted according to the tightness of the hose, ensuring that the second guide member is always in contact with the hose. This maintains the guiding function of the second guide member throughout the entire hose retrieval process, while also preventing over-tensioning of the hose and improving the service life of the hose.

[0115] like Figure 9 and Figure 11 As shown, in some embodiments, the hose reeling device 10 further includes a hose clamping mechanism 300. The hose clamping mechanism 300 is located between the input end of the hose transport mechanism 100 and the hose guide assembly 210, and is connected to the hose transport mechanism 100 for clamping or releasing the hose. Specifically, the hose clamping mechanism 300 is located between two support assemblies 110 and is connected to the support assemblies 110. The hose clamping mechanism 300 is located between the input end of the hose transport assembly 120 and the hose guide assembly 210.

[0116] In this embodiment, the hose clamping mechanism 300 ensures that the hose is stably clamped during the retrieval process, preventing slippage or displacement of the hose during transportation. The clamping mechanism ensures that the hose will not accidentally detach during retrieval, thus avoiding potential safety hazards. This is crucial for firefighters, who need to quickly and safely retrieve hoses in emergency situations.

[0117] Furthermore, the hose reeling device 10 includes two hose clamping mechanisms 300, which are respectively arranged at both ends of the hose transport assembly 120. Specifically, one hose clamping mechanism 300 is located at the input end of the hose transport assembly 120, and the other hose clamping mechanism 300 is located at the output end of the hose transport assembly 120.

[0118] like Figure 10 As shown, the hose clamping mechanism 300 further includes a first clamping roller 310, a second clamping roller 320, and a roller drive assembly 330. The first clamping roller 310 is rotatably engaged with the hose transport mechanism 100 about the width of the hose, and is located on one side of the hose and in contact with it. The second clamping roller 320 is located on the other side of the hose. The roller drive assembly 330 is mounted on the hose transport mechanism 100 and is connected to the second clamping roller 320, used to drive the second clamping roller 320 closer to or further away from the first clamping roller 310 to clamp or release the hose.

[0119] In this embodiment, the water hose is clamped by the first clamping roller 310 and the second clamping roller 320, and the first clamping roller 310 rotates and cooperates with the water hose transport mechanism 100 around the width direction of the water hose, which can reduce the friction between the first clamping roller 310 and the water hose and improve the service life of the water hose.

[0120] Specifically, the two ends of the first clamping roller 310 are respectively engaged with the support component 110 in a rotatable engagement with the width direction of the water hose, and the second clamping roller 320 is engaged with the rolling drive component in a rotatable engagement with the width direction of the water hose. The first clamping roller 310 and the second clamping roller 320 clamp the water hose. During the water hose recovery process, both the first clamping roller 310 and the second clamping roller 320 rotate, reducing the friction on the water hose.

[0121] For example, the hose clamping mechanism 300 includes two second clamping rollers 320 and two roller drive assemblies 330; the two second clamping rollers 320 are arranged along the axial direction of the first clamping roller 310, that is, along the width direction of the hose, and the two roller drive assemblies 330 correspond one-to-one with the two second clamping rollers 320. By setting two second clamping rollers 320, the power of the roller drive assembly 330 can be reduced, thereby reducing costs.

[0122] like Figure 10As shown, the roller drive assembly 330 further includes a roller drive component 333 and a connector 334. One end of the connector 334 is rotatably engaged with the second clamping roller 320 about the width of the hose. The roller drive component 333 is mounted on the hose transport mechanism 100; the other end of the roller drive component 333 is connected to the connector 334, and is used to drive the second clamping roller 320 closer to or away from the first clamping roller 310 via the connector 334. The roller drive component 333 presses the second clamping roller 320 against the first clamping roller 310 through the connector 334, achieving stable clamping of the hose. This clamping method is not only firm and reliable, but also ensures that the hose will not slip or loosen during transport, thereby improving transport efficiency.

[0123] Furthermore, the roller drive component includes a clamping cylinder. The clamping cylinder is connected to the hydraulic system circuit of the multi-functional fire truck.

[0124] Specifically, the clamping cylinder is installed on the side of the support assembly 110 away from the hose conveying assembly 120. The drive end of the clamping cylinder is hinged to one end of the connector 334, and the other end of the connector 334 extends along the width of the hose and rotates in cooperation with the second clamping roller 320. The lower part of the connector 334 abuts against the upper side of the support assembly 110. When the drive end of the clamping cylinder moves up and down, the connector 334 uses the abutment position as a fulcrum to lift or lower the second clamping roller 320, thereby clamping or releasing the hose.

[0125] In some embodiments, the hose reeling device 10 further includes a tension detection module and a control module; the tension detection module is used to detect the tension of the hose. The control module is electrically connected to the tension detection module and the guide drive assembly 220. The control module outputs control commands according to the tension to control the guide drive assembly 220 to rotate the hose guide assembly 210 around the width of the hose, ensuring that the hose guide assembly 210 is in contact with the hose.

[0126] Furthermore, the tension detection module includes a tension meter or a distance meter; the tension meter is used to detect the tension of the hose; the distance meter is used to detect the actual distance between the hose and the hose guide assembly 210. When the tension is greater than a tension threshold, and / or the actual distance is greater than a distance threshold, the control module controls the guide drive assembly 220, that is, controls the piston rod of the hydraulic cylinder to extend. The piston rod drives the first guide member 211 to rotate the first guide roller 212 upwards until the tension is less than the tension threshold, and / or the actual distance is less than the distance threshold. This allows for automatic adjustment of the guide drive assembly 220, enabling real-time adjustment of its position based on the hose's stretching, ensuring the hose is not overstretched and improving its service life.

[0127] Furthermore, the hydraulic system of the multi-functional fire truck provides hydraulic oil to the guide drive assembly 220, the belt drive component, and the roller drive component 333 to control them. In this embodiment, by connecting the guide drive assembly 220, the belt drive component, and the roller drive component 333 to the hydraulic system's oil circuit, the various power sources of the hose reeling device 10 can be controlled through the hydraulic system. This simplifies the structure, improves reliability and stability, reduces costs, and simultaneously provides control precision and efficiency.

[0128] 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.
