Description

Technical Field

[0001] This invention relates to the field of hose winding, and in particular to a hose winding device. Background Technology

[0002] With social development, fire fighting and disaster relief have received increasing attention and importance. In major disasters, such as explosions, fires, and floods, not only are traditional small-diameter fire hoses (e.g., DN65, DN80) needed, but large-diameter hoses (e.g., DN250, DN300) are also increasingly used for large-scale water transport and drainage. Existing fire hose reeling devices are still primarily designed for small-diameter hoses, and each device can only reel in one fixed size. Different hose diameters require different devices or different sized reels. Furthermore, manual reeling remains common, making the process time-consuming, labor-intensive, and inefficient. With the widespread use of large-diameter water hoses, these hoses have distinct characteristics compared to small-diameter hoses. They are heavier per unit length, requiring greater torque for winding, making manual winding generally impossible. Therefore, existing fixed-diameter winding devices are unsuitable for winding large-diameter hoses. Furthermore, after use, large-diameter hoses have a greater self-weight and more residual liquid, increasing friction with the ground. During winding, residual liquid needs to be squeezed out for efficient winding and better protection of the hose. Simultaneously, proper guidance is required during winding to ensure neat and compact winding, minimizing the volume of the wound hose for easy unloading and transportation.

[0003] As can be seen from the existing authorized invention patent CN104108621B, which relates to a small water hose winding device, the disclosed technical solution is limited to winding small-diameter water hoses. This technical solution is not suitable for winding large-diameter water hoses because large-diameter water hoses are heavier. When using the existing technical solution to wind large-diameter water hoses, the winding device has a large rotational friction, which makes the unilateral winding stability worse. After the water hose is wound, it cannot be easily unloaded and removed.

[0004] Another authorized utility model patent CN210339962U relates to an automatic fire hose reeling device. Because large-diameter hoses are heavy, the reeling device has high rotational friction. The disclosed technical solution cannot provide sufficient and effective reeling power for large-diameter hoses. Furthermore, the large-diameter hoses are too heavy to be easily removed manually after reeling.

[0005] Another authorized utility model patent, CN201920213337, relates to a fire hose winding device. Although a motor can be used for winding, this technical solution fails to take into account the characteristics of large-diameter hoses, such as their weight and size. Therefore, in this technical solution, the winding mechanism suffers from poor dynamic stability and insufficient power in the later stages of winding due to the lack of a design to reduce friction when the hose is heavy. Existing technical solutions also cannot solve the problem of how to conveniently remove large-diameter hoses from the device.

[0006] It is clear from existing technical solutions that current hose reeling devices are mainly designed for small-diameter, lightweight hoses. These devices have fixed hose sizes and cannot reel in hoses of various diameters. Furthermore, they do not consider the greater friction and torque required when reeling in heavier hoses. Using the existing mechanical structure, the high friction causes the reeling device to vibrate violently during reeling, resulting in poor dynamic stability and easy damage to rotating parts. It also makes it difficult to easily remove the reeled large-diameter hoses. Existing technology also fails to consider that large-diameter hoses, due to their large size and weight, experience greater friction with the ground during reeling. Dragging the hose during reeling increases its risk of damage, and radial movement during reeling further increases its size, making unloading and transportation difficult. Summary of the Invention

[0007] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is that existing hose reel winding devices can only wind hoses of fixed diameter. If hoses of different diameters need to be winded, different winding devices or reels must be used, which is time-consuming and labor-intensive. Most existing hose reel winding devices adopt manual winding methods. Even if hydraulic or electric mechanisms are used for winding, the overall winding mechanism does not take into account the characteristics of large-diameter hoses, such as large weight and volume, high winding friction, high winding torque, and high dynamic stability requirements. This makes the existing technical solutions unable to wind large-diameter hoses well. At the same time, it does not consider how to reduce the wear of hoses due to friction with the ground when winding large-diameter hoses, or how to make the entire hose winding neat and efficient, and how to easily remove the hoses from the hose reel winding device after winding.

[0008] Therefore, those skilled in the art are dedicated to developing a hose reel winding device that provides winding power via hydraulics or an electric motor. Bearings serve as the main components for load-bearing and rotating parts of the winding mechanism, achieving low-resistance automatic hose reel winding. The entire winding device utilizes the hose itself or a connector as the winding axis. An adjustable-width limiting mechanism at the front end of the winding frame accommodates hoses of different diameters, ensuring no radial displacement of the hose during winding and resulting in a neat and compact hose after winding. By incorporating a roller set, the wound hose can be conveniently placed on the roller set for easy transport and unloading from the hose reel winding device.

[0060] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0061] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations.

To make the illustrations clearer, the thickness of components is appropriately exaggerated in some places in the drawings. Dashed boxes are used in the drawings to indicate components included in a mechanism, representing a mechanism that performs a certain function.

[0062] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", "edge", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0063] Example 1

[0064] like Figure 1As shown, a hose reel winding device provided by the present invention includes a winding frame 1, a drive mechanism 2, a winding fixing mechanism 4, a roller group 5, and a limiting mechanism 6. The winding frame 1 is used to bear the weight of the hose reel winding device itself and the weight of the hose being wound, and can provide stable support during hose reel winding operations. The overall design facilitates the stable placement or fixing of the reel winding device on vehicles or other equipment for reel winding operations. The drive mechanism 2 is fixedly mounted on the winding frame and includes an electric motor or a hydraulic motor, as well as a drive control unit and a control box. The drive control unit is located in the control box and is configured to adjust and control the electric motor or hydraulic motor to drive the winding fixing mechanism 4 to perform hose reel winding operations. The winding fixing mechanism 4 includes a rotating part and a winding part, and the rotating part includes a bearing. The rotating part is connected to the winding frame 1 via a bearing. The rotating part is configured to rotate relative to the winding frame using the bearing for hose winding operations. The winding part is located at one end of the winding fixing mechanism and can fix the hose or hose connector. Optionally, it can be a winding device such as a clamp, gripper, or winding rod. In a preferred embodiment, the winding part is a winding rod. Because the rotating part uses a bearing, it not only effectively supports the weight of the hose being wound but also greatly reduces the winding friction during hose winding operations, thus significantly protecting the winding fixing mechanism 4 and extending its service life. The winding fixing mechanism 4 is driven by the winding power provided by the drive mechanism 2. After the winding part fixes the hose or hose connector, the hose is wound up. The fixed mechanism 4 is driven by the drive mechanism 2 to rotate and perform the hose winding operation. In an optional scheme, one set of winding fixing mechanisms 4 is provided on each side of the winding frame 1, wherein the fixed winding mechanism 4 on one side is driven by the drive mechanism 2, and the rotation axes of the two sets of winding fixing mechanisms 4 are set on the same rotation axis, which can improve the dynamic stability during the hose winding operation. The roller group 5 includes at least two or more rollers. At least one roller is provided at the bottom of the winding frame 1, which guides the hose to the winding fixing mechanism 4 to avoid damage to the hose during the winding process, and is used to carry the wound hose. At least one roller is provided at the front end of the winding frame 1. The roller provided at the front end of the winding frame 1 is set to a horizontal position slightly higher than the roller provided at the front end of the winding frame 1. The horizontal position of the bottom rollers not only guides the water hose to the winding and fixing mechanism 4, but also allows the water hose to squeeze out residual liquid by its own gravity when passing through the front rollers. The front rollers also provide appropriate obstruction for the water hose wound on the bottom rollers of the winding frame 1, preventing it from rolling out accidentally. At the same time, by utilizing the rotational characteristic of the rollers, appropriate pushing or pulling forces can be applied to the water hose placed on the bottom rollers of the winding frame 1, which can easily roll the water hose forward by relying on the rollers, thereby unloading it from the winding device. The roller group 5 reduces the friction during the water hose winding process, achieving efficient winding operations, protecting the water hose, and facilitating water hose transportation and unloading.The limiting mechanism 6 includes a limiting part whose width can be adjusted according to the hose diameter. The limiting part is configured to adjust according to the width of the hose to be wound, thus preventing radial movement of the hose when it is laid flat through the limiting part. After the width is appropriately adjusted according to the diameter of the hose to be wound, no radial movement will occur when the hose is laid flat through the limiting part, achieving the technical effect of neat sides and small volume of the wound hose.

The limiting mechanism 6 and the front rollers of the roller group 5 are both mounted on the front frame 103. Preferably, the front frame 103 is movably connected to the inner side plate 110 and the outer side plate 111. The front frame 103 is configured to be able to flip up to free up working space and achieve the technical effect of facilitating the rolling out of the water belt.

In the preferred solution of this embodiment, two inflatable rubber directional front wheels 105 are provided at the front of the winding frame 1, and one universal wheel 106 is provided in the center of the rear of the winding frame 1. When the water hose is wound up, the water hose winding device can move forward with the water hose winding operation, reducing the friction between the water hose and the ground caused by dragging the water hose, thereby achieving the technical effect of protecting the water hose and extending the service life of the water hose. The overall solution also achieves the technical effect of enabling the water hose winding device to be moved to any location, facilitating the transportation of water hose.

Preferably, the push rod 101 is sleeved on the rear of the winding frame 1, and multiple through holes 107 are provided at the sleeve joint between the push rod 101 and the rear of the winding frame 1. A wing bolt 108 is used to pass through the holes 107 to fix the push rod 101 to the rear of the winding frame 1. The height of the push rod 101 can be adjusted by pulling the push rod 101 and fixing it to the holes 107 at different positions by the wing bolt 108, so as to facilitate the use of users of different heights.

The drive control unit includes a rechargeable battery and a speed control device 203. The DC motor 201 is driven by a rechargeable battery, preferably a lithium battery. The speed control device 203 adjusts and controls the DC motor 201 and the reducer 202 to perform the winding operation. In one preferred embodiment, the winding frame adopts the technical solution in Embodiment 4.

[0073] Example 6

[0074] Reference Figure 7 In a preferred embodiment, the winding and fixing mechanism 4 is fixedly connected at one end to the power shaft of the driving mechanism 2 and is directly driven by the driving mechanism 2. In one preferred embodiment, the winding frame adopts the technical solution in embodiment four.

[0075] Example 7

[0076] Reference Figure 8 Based on Embodiment 1, in a preferred technical solution, the winding and fixing mechanism 4 is connected to the driving mechanism 2 through the transmission mechanism 3, and the winding power is transmitted to the winding and fixing mechanism 4 through the transmission mechanism 3; in one preferred solution of this embodiment, the winding frame adopts the technical solution in Embodiment 4.

[0077] Example 8

[0078] Reference Figure 9 and Figure 10Based on Embodiment 7, the transmission mechanism includes a driving gear 332, a driven gear 334, and a connecting gear 333. Preferably, the driving gear 332 is fixedly connected to the drive shaft of the drive mechanism 2 via a flat key 301, and the driven gear 334 is fixedly connected to a winding and fixing mechanism on one side. In a preferred embodiment, the rotating part of the winding and fixing mechanism includes a sleeve 405, and the driven gear 334 is fixedly sleeved with the sleeve 405. The connecting gear 333 includes at least one gear, which meshes with the driving gear 332 and the driven gear 334 to transmit winding power. Optionally, the driven gear 334 can be replaced with a bearing with teeth on the outer ring or the inner ring. In a preferred embodiment, the driven gear 334 is a bearing with teeth on the outer ring. The bearing is fixedly connected to the sleeve 405, the inner ring of the bearing is fixedly connected to the winding frame 1, and the outer ring gear of the bearing meshes with the connecting gear 333, thereby combining the functions of the driven gear and the winding bearing. Preferably, the connecting gear 333 includes one gear that meshes with the driving gear 332 and the driven gear 334 to drive the rotating part of the winding fixing mechanism to perform winding operations. By adjusting the transmission ratio of the connecting gear set, the torque can be increased, the winding speed can be reduced, and the stability of the winding operation can be improved. Those skilled in the art should know that if a bearing with teeth on the inner ring is used, it is only necessary to fix the outer ring of the bearing to the winding frame 1 and fix a transition gear on the sleeve 405 with a flat key. The transition gear meshes with the teeth of the inner ring of the bearing and the connecting gear 333 at the same time to achieve the same technical effect.

Regardless of whether the water hose has a joint, after closing, the metal rods wind the water hose around the water hose for winding operation when the rotating part rotates. After the water hose winding operation is completed, the steel pins 411 on both sides are pulled out respectively, so that the metal rods and the water hose fall onto the roller together and roll them out of the winding frame.

This can not only achieve the effect of squeezing out the residual liquid in the water hose by the gravity of the water hose when it passes through the front rollers, but also provide appropriate obstruction for the water hose wound on the rollers at the bottom of the winding frame 1 to prevent accidental rollout. At the same time, by utilizing the rotational characteristic of the rollers, appropriate pushing or pulling force can be applied to the water hose placed on the rollers at the bottom of the winding frame 1, so that the water hose can be easily rolled forward by the rollers, thereby unloading it from the winding device.
