Description

Technical Field

[0001] This utility model relates to the field of building fire protection technology, and in particular to a fire hose reeling device. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water in temporary fire boxes at construction sites. Traditional fire hoses have a rubber inner lining and an outer surface covered with flax woven fabric. Both ends of the fire hose are connected to metal joints, which can be used to connect another hose to extend the distance or to connect nozzles to increase the liquid spray pressure.

[0003] Currently, fire hose winding mainly relies on manual labor, which is time-consuming, labor-intensive, and results in uneven winding. Existing winding devices can also be used; for example, Chinese invention patent CN114917517B discloses a fire hose winding vehicle comprising: a vehicle body with a dashboard and a handle at the front; a front wheel assembly including a front axle, a pair of front wheels, a pair of front wheel supports, and a mechanical roller shaft, wherein the front axle passes through the dashboard via bearings and mounts the pair of front wheels; a rear wheel assembly including a rear axle and a pair of rear wheels, wherein the rear axle passes through the dashboard via bearings and mounts the pair of rear wheels; and a winding assembly including a U-shaped extension frame, a rotating rod, a winding motor, and a winding shaft. This fire hose winding vehicle is large, complex in structure, expensive, occupies a large space, and is inconvenient to use.

[0004] Furthermore, when manually or using a winding device to wind up fire hoses, residual water cannot be completely drained from the hoses, and this residual water can easily leak out during transportation and storage, affecting the environment. Therefore, there is a need to provide a fire hose winding device that can solve the problems of time-consuming and labor-intensive manual winding of fire hoses, large size, complex structure and high cost of winding vehicles, and the inability to completely drain residual water from the hoses in existing technologies. Summary of the Invention

[0005] The purpose of this utility model is to provide a fire hose reeling device that can solve the problems of time-consuming and labor-intensive manual fire hose reeling, large size, complex structure and high cost of the reeling vehicle, and inability to completely drain residual water from the hose in the existing technology.

[0006] This utility model is implemented as follows:

[0007] A fire hose reel device includes a handle, a bearing, a reeling frame, outriggers, and a reeling clamp. The reeling frame is a cylindrical frame structure with one open end. The outer ring of the bearing is coaxially fixed to the center of the other end of the reeling frame. A pair of outriggers are symmetrically installed on both sides of the bottom of the reeling frame, so that the axial direction of the reeling frame is parallel to the ground. One end of the handle is coaxially fixed to the outer end of the inner ring of the bearing, so that the handle can be rotatably located on the outer side of the other end of the reeling frame. The reeling clamp is fixedly connected to the inner end of the inner ring of the bearing, so that the reeling clamp can be rotatably located inside the reeling frame. The metal connector at one end of the fire hose is clamped onto the reeling clamp, so that the fire hose is wound around the rotating reeling clamp and located inside the reeling frame.

[0008] The winding frame includes a first circular frame, a second circular frame, and connecting rods; the first circular frame and the second circular frame are annular structures with the same diameter and are arranged coaxially and parallel to each other, and the first circular frame and the second circular frame are connected into an integral structure by several connecting rods; the outer ring of the bearing is coaxially installed at the center of the first circular frame, and the support leg is connected between the first circular frame and the second circular frame.

[0009] One of the connecting rods is fitted with a sleeve, the inner diameter of which is larger than the diameter of the connecting rod, so that the sleeve is rotatably mounted on the side of the winding clamp. The fire hose rests on the sleeve and extends into the winding frame.

[0010] The aforementioned winding clamp has a U-shaped structure with one end open and the other end closed. The middle of the closed end of the winding clamp is fixedly connected to the inner end of the inner ring of the bearing. The opening width of the U-shaped structure is smaller than the diameter of the metal joint of the fire hose and larger than the thickness of the fire hose, so that the metal joint of the fire hose is clamped at the open end of the winding clamp, and the fire hose is wound around the winding clamp.

[0011] Several reinforcing rods are installed at intervals inside the first circular frame, and the reinforcing rods are arranged radially between the outer ring of the bearing and the first circular frame.

[0012] The outrigger has a U-shaped structure with one end open and the other end closed. The two open ends of the outrigger are respectively connected to the lower sides of the first and second circular frames, and the closed end of the outrigger is attached to the ground.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. The entire device of this utility model is made of welded round steel pipes. It can be adapted to the actual winding requirements of fire hoses. It is small in size, light in weight, easy to obtain materials and manufacture, low in cost, occupies little space, and is convenient for transportation and storage.

[0015] 2. This utility model features a handle, bearings, and a winding clamp. The metal connector of the fire hose is secured to the U-shaped winding clamp. When the handle is manually turned, it drives the winding clamp to rotate synchronously through the bearings, thereby winding the fire hose around the winding clamp within the winding frame. Manual winding is easy, labor-saving, and efficient, and the wound fire hose is neat and aesthetically pleasing. Simultaneously, the circular motion of the U-shaped winding clamp raises the portion of the fire hose within the winding frame, allowing residual water to drain out before winding, ensuring complete drainage and preventing leakage during later transportation and storage that could impact the environment.

[0016] 3. This utility model features a winding frame and support legs. The first circular frame is reinforced with reinforcing rods and fitted with bearings, ensuring the functionality and structural strength of the entire device. The second circular frame serves as the open end of the winding frame, facilitating the removal of the wound fire hose. Simultaneously, the rotation of the sleeve prevents surface wear caused by direct friction between the fire hose and the connecting rod. The support legs are symmetrically arranged in pairs on both sides of the bottom of the winding frame, ensuring the stability of the entire device on the ground during use and providing high operational safety.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Please see the appendix Figure 1 A fire hose reel device includes a handle 1, a bearing 2, a reeling frame, support legs 4, and a reeling clamp 7. The reeling frame is a cylindrical frame structure with one open end. The outer ring of the bearing 2 is coaxially fixed to the center of the other end of the reeling frame. A pair of support legs 4 are symmetrically installed on both sides of the bottom of the reeling frame, so that the axial direction of the reeling frame is parallel to the ground. One end of the handle 1 is coaxially fixed to the outer end of the inner ring of the bearing 2, so that the handle 1 is rotatably located on the outer side of the other end of the reeling frame. The reeling clamp 7 is fixedly connected to the inner end of the inner ring of the bearing 2, so that the reeling clamp 7 is rotatably located inside the reeling frame. The metal connector at one end of the fire hose is clamped onto the reeling clamp 7, so that the fire hose is wound around the rotating reeling clamp 7 and located inside the reeling frame.

[0021] Preferably, the handle 1, the winding frame, the support leg 4, and the winding clamp 7 can all be made of round steel pipes, which are easy to source and manufacture, have a simple structure, low cost, and the volume of the entire device can be customized according to actual usage needs, which helps to reduce volume and weight, and makes it easier to transport and store.

[0022] Handle 1 can be a Z-shaped handle with a long lever arm, making rotation easy and effortless. Outriggers 4 are installed in pairs, and their number can be adjusted to suit the weight of the fire hose to be wound. The outriggers 4 rest against the ground from both sides, providing a large contact area and ensuring the stability of the entire winding frame during use. The winding clamp 7 is used to wind the fire hose within the winding frame. The dimensions of the winding clamp 7 and the winding frame can be adjusted to suit the length of the fire hose to be wound.

[0023] In use, by rotating the inner ring of bearing 2 relative to the outer ring using handle 1, the inner ring of bearing 2 drives the winding clamp 7 to rotate synchronously, thereby winding the fire hose around the winding clamp 7 and placing it within the winding frame. The winding operation is convenient and simple. After winding, the entire device can be laid down, allowing the wound fire hose to be poured out from the opening end of the winding frame for easy removal.

[0024] The winding frame includes a first circular frame 5, a second circular frame 6, and connecting rods 9; the first circular frame 5 and the second circular frame 6 are circular ring structures with the same diameter and are arranged coaxially and parallel to each other. The first circular frame 5 and the second circular frame 6 are connected into an integral structure by several connecting rods 9; the outer ring of the bearing 2 is coaxially installed at the center of the first circular frame 5, and the support leg 4 is connected between the first circular frame 5 and the second circular frame 6.

[0025] Preferably, the first circular frame 5 and the second circular frame 6 can be made into a ring structure by bending and welding circular steel pipes. The two ring structures are connected into a whole by a connecting rod 9. The diameters of the first circular frame 5 and the second circular frame 6 and the length of the connecting rod 9 can be adaptively adjusted according to the winding requirements of the fire hose. The overall structure of the winding frame has high strength, light weight, small size, and low cost.

[0026] One of the connecting rods 9 is fitted with a sleeve 8, the inner diameter of which is slightly larger than the diameter of the connecting rod 9, so that the sleeve 8 is rotatably mounted on the side of the winding clamp 7, and the fire hose rests on the sleeve 8 and extends into the winding frame.

[0027] Since the sleeve 8 is slightly larger than the connecting rod 9, the sleeve 8 can rotate relative to the connecting rod 9. During the process of the winding clamp 7 winding the fire hose, the rotation of the sleeve 8 avoids the sliding friction between the fire hose and the connecting rod 9, which helps to protect the fire hose and reduce wear.

[0028] The winding clamp 7 has a U-shaped structure with one end open and the other end closed. The middle of the closed end of the winding clamp 7 is fixedly connected to the inner end of the inner ring of the bearing 2. The opening width of the U-shaped structure is smaller than the diameter of the metal joint of the fire hose and larger than the thickness of the fire hose, so that the metal joint of the fire hose is clamped at the open end of the winding clamp 7, and the fire hose is wound around the winding clamp 7.

[0029] The opening width of the retractor 7 is slightly smaller than the diameter of the metal connector of the fire hose. Since the fire hose is a flexible hose made of rubber and braided material, it is relatively flat when not in use, so that the metal connector can be locked on the retractor 7. The fire hose passes through the retractor 7, making it easy to wrap the fire hose around the retractor 7 when it rotates.

[0030] Meanwhile, because the winding clamp 7 has a U-shaped structure, when the winding clamp 7 rotates around its closed end, the movement trajectory of the rods at both ends of the opening of the winding clamp 7 is circular. During the upward rotation of the rods, the portion of the fire hose located within the winding frame is raised, making it higher than the portion of the fire hose located outside the winding frame. This allows residual water in the fire hose to flow outwards under gravity, ensuring that there is no residual water in the wound fire hose, thus allowing all residual water in the wound fire hose to be drained. During the downward rotation of the rods, the winding and coiling action of the fire hose is completed. With the repeated circular motion of the rods, the drainage and winding of the fire hose are synchronized.

[0031] Several reinforcing rods 3 are installed at intervals inside the first circular frame 5, and the reinforcing rods 3 are arranged radially between the outer ring of the bearing 2 and the first circular frame 5.

[0032] Preferably, the reinforcing rod 3 can be made of round steel pipe, and the length of the reinforcing rod 3 can be adapted to the radius of the first circular frame 5. Six reinforcing rods 3 can be arranged radially at equal intervals to enhance the structural strength of the first circular frame 5. At the same time, one end of each reinforcing rod 3 is concentrated at the center of the first circular frame 5 to provide a stable and reliable mounting point for the bearing 2.

[0033] The support leg 4 has a U-shaped structure with one end open and the other end closed. The two ends of the open end of the support leg 4 are respectively connected to the lower side of the first circular frame 5 and the second circular frame 6, and the closed end of the support leg 4 is attached to the ground.

[0034] The width of the support leg 4 is consistent with the distance between the first circular frame 5 and the second circular frame 6, thus providing stable support for the first circular frame 5 and the second circular frame 6 through the open ends of the support leg 4, and transferring the load to the ground through the closed ends of the support leg 4. The closed ends of the support leg 4 are elongated strip structures with the same width as the winding frame, resulting in a large contact area with the ground, high support stability, and ensuring the stability of the device in use.

[0035] Preferably, the support leg 4 can be made by vertically welding three round steel pipes.

[0036] Please see the appendix Figure 1 The method of use and working principle of this utility model are as follows:

[0037] The entire device is mounted on the ground via a pair of support legs 4, which can be stepped on to improve the stability of the device during use.

[0038] Insert one end of the fire hose into the winding frame from the top of the sleeve 8. Since the opening width of the winding clamp 7 is smaller than the diameter of the metal connector, the metal connector of one end of the fire hose can be inserted into the winding clamp 7 through the opening end. Manually turn the handle 1 clockwise as shown in the figure, so that the inner ring of the bearing 2 drives the winding clamp 7 to rotate clockwise. As the winding clamp 7 rotates, the fire hose is wound around the winding clamp 7.

[0039] During the process of winding up the fire hose, since the sleeve 8 is located on the left side of the winding clamp 7, when the U-shaped winding clamp 7 rotates clockwise, its left end will be raised above the sleeve 8, so that the fire hose forms an incline from the bearing 2 towards the outside of the winding frame, which is higher on the inside and lower on the outside. This allows the water to flow to the unwinding part of the fire hose, ensuring that the remaining water in the wound fire hose is drained.

[0040] Continue turning handle 1 until the fire hose is wound to the other end and all the remaining water is discharged from the fire hose, thus completing the winding of the fire hose within the winding frame.

[0041] Loosen the foothold on the branch leg 4 and lay the entire device down so that the second circular frame 6 of the winding frame faces downwards on the ground. Then lift the entire device upwards, and under the action of gravity, the wound fire hose will disengage from the winding clamp 7 and be placed on the ground, allowing for subsequent transportation and storage of the wound fire hose. Alternatively, the entire device and the fire hose can be transported and stored simultaneously, with the winding frame providing protection for the fire hose.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
