Description

Technical Field

[0001] This utility model relates to the technical field of fire hose reeling and laying devices, specifically to a fire hose reeling and laying device that can be quickly deployed. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. They are usually made of a tubular fabric layer woven with warp and weft threads and a lining, which are combined by steam vulcanization or adhesives. They are soft, coilable, round or flat tubular bodies.

[0003] In fire rescue operations, the rapid deployment of fire hoses is crucial for controlling and extinguishing fires. Traditional methods of fire hose storage, such as manually coiling them and placing them on fire trucks or in fire boxes, have several drawbacks. Firstly, manually coiled hoses are prone to tangling and knotting during unwinding, severely impacting deployment speed and delaying rescue efforts. Secondly, manually winding fire hoses requires first smoothing them out before winding them up, a cumbersome process that wastes considerable time. Therefore, we propose a rapidly deployable fire hose storage and deployment device. Utility Model Content

[0004] The purpose of this invention is to provide a fire hose storage and laying device that can be quickly deployed, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fire hose storage and laying device capable of rapid deployment includes a support plate fixedly installed on an external frame. A first servo motor is fixedly installed on the rear side of the support plate. The output shaft of the first servo motor passes through the support plate and is fixedly installed with a spiral rod. A vertically arranged stud is fixedly installed on the rear end of the spiral rod. A clamping rod is provided above the spiral rod. The clamping rod is sleeved on the stud and slidably connected to the stud. A threaded knob is threadedly connected to the stud. Two symmetrical rotating shafts are rotatably connected to the front side of the support plate. A conveying roller is fixedly installed on the rotating shaft. A second servo motor is coaxially arranged at the end of one of the rotating shafts. Gears are fixedly installed at the same end of both rotating shafts, and the upper and lower gears mesh with each other.

[0007] Preferably, both the clamping rod and the surrounding rod have circular cross-sections, and a threading gap is provided between the clamping rod and the surrounding rod.

[0008] Preferably, a support frame is fixedly installed on both the top and bottom surfaces of the support plate, a support plate is fixedly installed on the end rod of the support frame, and the other end of the rotating shaft is rotatably connected to the corresponding support plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a fire hose storage and laying device that can be quickly deployed, including a support plate 1 fixedly installed on an external frame. Specifically, the support plate 1 can be installed on a fire truck or in a fire box at a corresponding location. A first servo motor 2 is fixedly installed on the rear side of the support plate 1. The output shaft end of the first servo motor 2 passes through the support plate 1 and is fixedly installed with a winding rod 20, so that the fire hose can be stored or deployed around the winding rod 20, providing a convenient power basis for hose storage and laying.

[0029] Specifically, a vertically arranged stud 21 is fixedly installed on the rear end of the spiral rod 20. A clamping rod 22 is provided above the spiral rod 20. The clamping rod 22 is sleeved on the stud 21 and slidably connected to the stud 21. A threaded knob 24 is threadedly connected to the stud 21. The cross-sections of both the clamping rod 22 and the spiral rod 20 are circular. A webbing gap 23 is provided between the clamping rod 22 and the spiral rod 20 to enable the clamping and fixing of the fire hose passing through the webbing gap 23, ensuring that the end of the fire hose will not come loose during the winding process.

[0030] In this embodiment, two symmetrical rotating shafts 3 are rotatably connected to the front side of the support plate 1. A conveying roller 30 is fixedly installed on the rotating shaft 3. A second servo motor 31 is coaxially arranged at the end of one of the rotating shafts 3. Gears 32 are fixedly installed at the same end of both rotating shafts 3. The two gears 32 mesh with each other. Through the transmission of the gears 32, the two conveying rollers 30 rotate synchronously, so that the fire hose can be stably supported and conveyed during laying and storage.

[0031] Specifically, support frames 10 are fixedly installed on the top and bottom surfaces of support plate 1. Support plates 11 are fixedly installed on the end rods of support frames 10. The other end of the rotating shaft 3 is rotatably connected to the corresponding support plate 11, so that the other end of the rotating shaft 3 is stably supported, ensuring the stability of the conveying roller 30 when rotating, extending the service life of the device, and ensuring that the device will not shake during operation.

[0032] Furthermore, the output shaft end of the second servo motor 31 is fixedly mounted on the corresponding rotating shaft 3, and the second servo motor 31 is fixedly mounted on the support plate 11 to ensure that the second servo motor 31 can work stably.

[0033] In addition, two symmetrical horizontal rods 4 are fixedly installed on the front side of the support plate 1. The horizontal rods 4 are located on the side of the conveying roller 30 away from the surrounding rod 20. A horizontally arranged support rod 40 is fixedly installed on the front side of the horizontal rod 4. Two symmetrical guide rollers 41 are rotatably connected to the end of the support rod 40 through a rotating shaft. The guide rollers 41 can guide the direction of the fire hose, prevent the hose from deviating during the laying process, make the hose laying path more controllable, and reduce the friction loss between the hose and other parts of the device. When the fire hose passes through the guide rollers 41, if the fire hose is folded, the folded part of the fire hose passes through the guide rollers 41, which can straighten the folded part of the fire hose.

[0034] It is worth noting that the distance between the two horizontal bars 4 is greater than the thickness of the fire hose, and the cross-section of the guide roller 41 is circular, which allows the fire hose to pass smoothly, reduces the obstruction when the hose passes through, and ensures the smoothness of the hose during the guiding process.

[0035] It is worth noting that the distance between the upper and lower support plates 11 is greater than 5cm, and the front side of the part between the two conveying rollers 30 is connected to the outside, so that the fire hose has enough operating space on the conveying rollers 30, which is convenient for firefighters to operate and can quickly complete the work of laying and storing the hose.

[0036] Finally, it should be noted that the first servo motor 2 and the second servo motor 31 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0037] When using the fire hose storage and laying device of this utility model that can be quickly deployed, first check whether the first servo motor 2, the second servo motor 31 and other components are normal. If it is necessary to store the fire hose, pass one end of the hose through the threading gap 23 between the guide roller 41, the conveying roller 30, the clamping rod 22 and the wrapping rod 20 in sequence, and place the end of the hose at the threading gap 23. Then rotate the threaded knob 24 so that the clamping rod 22 clamps the end of the hose on the wrapping rod 20.

[0038] Next, the first servo motor 2 is started, which drives the surrounding rod 20 to rotate, thereby achieving the winding of the water belt. At the same time, the second servo motor 31 is started, which drives the two conveyor rollers 30 to rotate synchronously via the gear 32, assisting in the smooth winding of the water belt. When the water belt passes through the guide roller 41, it guides the direction of the water belt, prevents deviation, and straightens any possible folds.

[0039] When it is necessary to lay the water hose, the first servo motor 2 is operated in reverse, and the water hose is unfolded around the ring rod 20. The conveying roller 30 rotates in the opposite direction to support and convey the water hose. The guide roller 41 continues to play its role to ensure that the water hose is laid along the predetermined path. Because the support plate 11 is reasonably spaced and the front of the conveying roller 30 is connected to the outside, firefighters can operate conveniently and quickly complete the laying of the water hose and connect it to the fire hydrant for fire fighting operations.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
