Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a fire hose reel device and a fire truck. Background Technology

[0002] Currently, automatic hose retraction on fire trucks mainly involves retracting the hose from the front of the truck. When retracting from the front, the hose passes over the top of the front and is then pulled into the truck bed. The drawbacks are that the retraction mechanism needs to span the entire top of the front of the truck, resulting in a long retraction mechanism and high cost. In addition, when the front of the truck is retracting the hose, it obstructs the driver's view, posing a certain safety hazard.

[0003] Therefore, it is necessary to develop a fire hose reel device and a fire truck to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to disclose a fire hose reel device and a fire truck.

[0005] The first objective of this invention is to provide a fire hose reel device.

[0006] The second objective of this invention is to provide a fire truck.

[0007] To achieve the first objective mentioned above, this utility model provides a fire hose reel device, including a truck body and a reeling section located on the top of the truck body;

[0010] The belt take-up assembly includes a first belt clamping assembly and a conveyor belt;

[0011] The strapping assembly includes a second strapping assembly;

[0012] With the second clamping assembly clamping the hose, the hose-handling assembly moves and folds the hose into the carriage.

[0013] Preferably, the shaft spacing between the driving pulley and the driven pulley of the conveyor belt is 1000-2000mm;

[0014] The carriage is divided longitudinally into several water hose storage chambers, and each water hose storage chamber is provided with an independent cover.

[0015] Preferably, when the take-up unit is operating, the take-up assembly moves toward the rear of the vehicle, and the projection of part of the take-up assembly toward the ground exceeds the projection of the vehicle body toward the ground.

[0016] Preferably, when the take-up section is not in operation, the take-up assembly moves toward the front of the vehicle, and the projection of the take-up assembly toward the ground does not exceed the projection of the carriage toward the ground.

[0040] Example 1

[0041] Reference Figures 1 to 9 As shown, this embodiment discloses a specific embodiment of a hose collecting device at the tail of a fire hose truck.

[0042] The embodiment provides a hose collecting device at the tail of a fire hose truck, reference Figures 1 to 9As shown, the system includes a carriage 1 and a belt-collecting section 2 located on top of the carriage 1. The belt-collecting section 2 includes a lateral movement assembly 21, a longitudinal track beam assembly 22, a belt-guiding assembly 23 that reciprocates along the track beam assembly 22, and a belt-collecting assembly 24 located at the rear end of the carriage 1. The belt-collecting assembly 24 is movably mounted on the track beam assembly 22. The lateral movement assembly 21 drives the track beam assembly 22 to move laterally. The belt-collecting assembly 24 includes a first belt-clamping assembly 241 and a conveyor belt 242. The belt-guiding assembly 23 includes a second belt-clamping assembly 231. When the second belt-clamping assembly 231 clamps the water hose, the belt-guiding assembly 23 moves and folds the water hose 3 into the carriage 1.

[0043] Specifically, see Figure 2 The direction of the vehicle's front is forward, and the opposite direction is the rear; the left and right sides of the front are transverse, and the front and back are longitudinal; the dashed line represents the hose 3, the solid arrow indicates the forward direction of the fire truck, and the dashed arrow indicates the retraction direction of the hose 3; the axle distance between the driving wheel 243 and the driven wheel 244 of the conveyor belt 242 is 1000-2000mm, and the overall length of the retraction assembly 24 is between 1200mm-2200mm. Compared with the traditional retraction assembly that needs to span the entire front of the vehicle, the overall length of the retraction assembly 24 is significantly reduced, and the manufacturing cost is significantly reduced; at the same time, the shorter retraction assembly 24 is also easier to retract. See [reference needed]. Figure 2 When the take-up unit 2 is in operation, the take-up assembly 24 moves towards the rear of the vehicle, and a portion of the take-up assembly 24 extends beyond the ground projection of the carriage 1, that is, the take-up assembly 24 extends beyond the rearmost end of the carriage 1 to facilitate take-up; see also Figure 1 When the retractable part 2 is not in operation, the retractable assembly 24 moves towards the front of the vehicle, and the projection of the retractable assembly 24 onto the ground does not exceed the projection of the carriage 1 onto the ground, that is, the retractable assembly 24 is completely retracted above the carriage 1.

[0044] See Figures 3 to 9The track beam assembly 22 includes a first track 221 and a second track 222 arranged in parallel; the belt feeding assembly 23 reciprocates along the first track 221 and the second track 222; a first inclined track 223 is provided at the rear end of the first track 221, and a second inclined track 224 is provided at the rear end of the second track 222; the first track 221, the second track 222, the first inclined track 223, and the second inclined track 224 are all provided with cavities for accommodating rollers; the bottom of the belt taking-up assembly 24 is provided with a first roller 245 and a second roller. 246; The first roller 245 moves along the cavity of the first inclined track 223, and the second roller 246 moves along the cavity of the second inclined track 224; the angle between the first inclined track 223 and the first track 221 is 0°-10°, and the angle between the second inclined track 224 and the second track 222 is 0°-10°, so that the take-up assembly 24 takes up the tape in a slightly downward-facing posture; the take-up assembly 24 moves along the first inclined track 223 and the second inclined track 224 to achieve a retracted state or an extended state; see also Figure 8 To ensure that the extended take-up assembly 24 is in a stable state, locking mechanisms 25 are respectively provided on both sides of the first track 221 and the second track 222. The locking mechanisms 25 lock the take-up assembly 24 to the track beam assembly 22.

[0045] See Figure 3 and Figure 4 The lateral movement assembly 21 includes a first lead screw assembly 211 and a second lead screw assembly 212. The first lead screw assembly 211 drives the front end of the track beam assembly 22, and the second lead screw assembly 212 drives the rear end of the track beam assembly 22. The working principle of the fire hose reel device at the rear of the vehicle is as follows: the hose 3 is fed into the reel assembly 24 from the rear of the vehicle, the conveyor belt 242 transports the hose 3, and the first clamping assembly 241 and the conveyor belt 242 cooperate to continuously transport the hose into the carriage 1; the second clamping assembly 231 clamps the hose. After the water hose moves from the rear end of the carriage 1 to the front end of the carriage 1, it is released and naturally continues to fall into the carriage 1. The second clamping assembly 231 moves from the front end of the carriage 1 to the rear end of the carriage 1, clamps the water hose 3, and then moves back to the front end of the carriage 1. Through the repeated clamping and reciprocating motion of the belt-handling assembly 23, the water hose is repeatedly folded into the carriage 1. When one row is folded to a certain height, the first lead screw assembly 211 and the second lead screw assembly 212 synchronously drive the track beam assembly 22 to move laterally above the next batch.

[0046] It should be noted that, see Figure 6The first clamping assembly 241 includes a first rotating shaft 2411 and a first connecting rod 2412 and a second connecting rod 2413 driven by the first rotating shaft 2411. The first connecting rod 2412 drives the first clamping wheel 2414 to swing, and the second connecting rod 2413 drives the second clamping wheel 2415 to swing. When the first clamping assembly 241 and the guide wheel 26 cooperate to convey the water belt 3, the first rotating shaft 2411 rotates and synchronously drives the first connecting rod 2412 and the second connecting rod 2413, thereby synchronously driving the first clamping wheel 2414 and the second clamping wheel 2415 to approach the guide wheel 26, realizing the clamping and conveying of the water belt 3. When the clamping and conveying of the water belt 3 is not required, the first rotating shaft 2411 rotates in the opposite direction, and drives the first clamping wheel 2414 and the second clamping wheel 2415 to swing and move away from the guide wheel 26 through the first connecting rod 2412 and the second connecting rod 2413, respectively. See also Figure 5 The second clamping assembly 231 includes a second rotating shaft 2311, a clamping plate 2316, and a third connecting rod 2312 and a fourth connecting rod 2313 driven by the second rotating shaft 2311. The third connecting rod 2312 drives the third clamping wheel 2314 to swing, and the fourth connecting rod 2313 drives the fourth clamping wheel 2315 to swing. When it is necessary to clamp the water hose 3, the second rotating shaft 2311 rotates under the drive of the drive assembly 2317 (such as an electric motor, hydraulic motor, etc.). Simultaneously, the third link 2312 and the fourth link 2313 are driven, which in turn drive the third clamping wheel 2314 and the fourth clamping wheel 2315 to swing and approach the clamping plate 2316, thus clamping the water hose 3. When clamping the water hose 3 is no longer needed, the second rotating shaft 2311 rotates in the opposite direction, driving the third clamping wheel 2314 and the fourth clamping wheel 2315 to swing in the opposite direction and move away from the clamping plate 2316 via the third link 2312 and the fourth link 2313 respectively. See also Figure 6 The first link 2412 includes a swing rod 24121, an intermediate rod 24122, and a V-shaped rod 24123. The first rotating shaft 2411 drives the swing rod 24121 to swing. Under the drive of the intermediate rod 24122, the V-shaped rod 24123 swings horizontally, thereby driving the first clamping wheel 2414 to swing, thereby clamping or releasing the water hose 3. The working principle of the second link 2413, the third link 2312, and the fourth link 2313 is the same as that of the first link 2412, and will not be described again here.

[0047] See Figure 9 The carriage 1 is divided longitudinally into several hose storage chambers 11. Each hose storage chamber 11 is provided with an independent cover 12. When folding the hose 3 into one of the hose storage chambers 11, the corresponding cover 12 is opened. After folding to a predetermined height, the cover 12 can be closed. Then, the hose can continue to be folded into the next hose storage chamber 11. After all the hoses are folded, all the covers 12 can be closed, ensuring that the carriage 1 is in a fully sealed state.

[0048] In this embodiment, the hose reel assembly 24 is located at the rear end of the vehicle compartment 1, with the hose inlet facing the rear of the compartment. This enables the hose to be reeled in from the rear of the fire truck. Compared to the traditional method of reeling in from the front of the vehicle, the hose reel assembly no longer needs to span the entire front of the vehicle. Compared to the traditional hose reel assembly, the length of the hose reel assembly 24 in this embodiment is significantly reduced, resulting in a significant reduction in cost. In addition, by reeling in the hose from the rear of the vehicle compartment, the hose no longer obstructs the driver's view.

[0049] Example 2

[0050] This embodiment provides a fire truck, including a cab 4 and a chassis 5. The fire hose reel device described in Embodiment 1 is installed on the chassis 5. When the fire truck is moving forward, the hose 3 is reeled in from the rear of the fire truck and folded back and forth into the truck body 1 by the reeling part 2. The hose no longer needs to be reeled in after passing over the top of the cab, which greatly shortens the length of the reeling assembly and significantly reduces the cost of the reeling mechanism.

[0051] The fire truck disclosed in this embodiment has the same technical solution as that in Embodiment 1. Please refer to Embodiment 1 for details, which will not be repeated here.
