[0041] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0042] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0043] like Figures 1 to 6 As shown in the figure, this utility model embodiment provides a hose transfer auxiliary device, which includes a support beam 1, a pipe clamp assembly 2, and two rollers 2, etc.

[0044] The support beam 1 is a horizontally arranged crossbeam that serves to support and bear the load. The pipe clamp assembly 3 is installed on the upper middle part of the support beam 1 and is used to clamp the water hose. Two rollers 2 are respectively rotatably installed at both ends of the support beam 1. The rotation of the rollers 2 can drive the support beam 1 and the pipe clamp assembly 3 on it to move.

[0045] In use, the hose clamp assembly 3 holds the hose to be moved, so that the hose transfer auxiliary device is relatively fixedly connected to the hose. Dragging the hose causes the roller 2 to rotate in contact with the ground, making the hose move more easily and quickly. Especially after the hose is filled with water, it can effectively reduce the labor intensity of firefighters dragging the hose, making the hose move more convenient and faster, and effectively improving the efficiency of hose movement and fire fighting operations. The device has a simple and compact structure, is quick to install and disassemble, and is convenient to store and transport.

[0046] In one implementation, such as Figures 1 to 3 As shown, the support beam 1 has an upward-facing mounting groove 11 along its length. The pipe clamp assembly 3 includes two opposing clamping pieces 31, the lower parts of which are located within the mounting groove 11, and are rotatably connected to the support beam 1 via a rotating shaft 32 and a torsion spring 33, respectively. The torsion spring 33 drives the two clamping pieces 31 to move closer together for clamping.

[0047] Furthermore, the two clamping plates 31 are arranged in a mirror-symmetrical configuration, with the lower part of one side being an arc-shaped portion 311 and the upper part of the other side being an upwardly and outwardly extending inclined portion 312. When the two clamping plates 31 are clamped, the arc-shaped portions 311 on both sides form a clamping channel to accommodate the hose. The arc-shaped portion 311 can better fit and clamp the hose. Preferably, the surface of the arc-shaped portion 311 is a non-slip surface, which can better clamp and fix it on the hose and prevent the hose transfer auxiliary device from sliding relative to the hose. The upper part of the two clamping plates 31 is set as an inclined portion 312, and the inclined portion 312 of the two clamping plates 31 is V-shaped, which makes it easy to move the clamping plates 31 and to allow the hose to rotate the clamping plates 31 under the action of gravity, thereby placing the hose between the two clamping plates 31.

[0048] A rotating shaft 32 is fixedly mounted on the lower part of the clamping plate 31 and extends to both sides of the clamping plate 31. The extended parts are rotatably connected to both sides of the mounting groove 11 of the supporting beam 1. A torsion spring 33 is sleeved on the rotating shaft 32, with one arm of the torsion spring abutting against the clamping plate 31 and the other arm abutting against the mounting groove 11 of the supporting beam 1. In use, applying force to both sides to pull the clamping plate 31 compresses the torsion spring 33, causing the two clamping plates 31 to separate; when the force is released, the torsion spring 33 drives the clamping plate 31 to return to its original rotation and achieve clamping.

[0049] The preferred torsion spring 33 is provided with 4 springs, one on each side of each clamping piece 31, which can make the clamping piece 31 rotate under force and hold stably.

[0050] In one embodiment, the support beam 1 has outwardly extending support plates 12 on both sides. The extension direction of the support plates 12 is perpendicular to the length direction of the support beam 1. The positions of the two support plates 12 correspond to the clamping parts of the two clamping pieces 31. They are used to support and clamp the water hose, increase the contact surface between the water hose and the support beam 1, prevent the water hose from bending, and make the clamping and cooperation with the water hose more stable and the transfer smoother.

[0051] Preferably, the support plate 12 is an upwardly curved arc-shaped support plate. Arc-shaped notches are provided on both sides of the mounting groove 11 of the supporting beam 1 to match the arc surface of the arc-shaped support plate. The two arc-shaped support plates are coaxially arranged, allowing for better fit and support of the fire hose. The arc-shaped notches, the arc-shaped support plate, and the arc-shaped portion 311 of the clamping plate form a clamping channel to adapt to the shape and size of the fire hose. It is typically designed to accommodate type 25, type 40, type 65, and type 80 fire hoses. Preferably, the arc-shaped notches and the arc-shaped support plate are designed to adapt to type 80 fire hoses, and the two clamping plates 31 can be adjusted to accommodate fire hoses of different diameters by adjusting the clamping opening.

[0052] In one implementation, such as Figure 7 and 8 As shown, a slot 34 is provided on the side of the two clamping pieces 31 that is far apart from each other. The slot 34 can open outward or downward. The hose transfer auxiliary device is also equipped with an elastic band. When in use, the two clamping pieces 31 clamp the hose, and the elastic band can be used to connect the upper part of the clamped hose to the slot 34 of the two clamping pieces 31, which helps to clamp the hose and makes the connection between the hose transfer auxiliary device and the hose more stable. This can effectively prevent the hose transfer auxiliary device from falling off the hose, especially when the hose is suspended in the air.

[0053] More preferably, the support beam 1 and the roller 2 are detachably rotatably connected. Quick installation and detachment can be achieved through plug-in / clamp-in locking. The support beam 1 and its clamp assembly 2 can be replaced according to the size of the hose, adapting to the transfer of hoses of different diameters; it can also be replaced when components are damaged, such as the roller 2 or the clamp assembly 3, making it more convenient to use and easier to store and transport.

[0054] In one implementation, such as Figure 1 , Figure 5 and Figure 6 As shown, roller 2 is a composite roller, which includes a hub 21, several roller supports 22 and several rollers 23, etc.

[0055] The hub 21 has a bearing coaxially mounted inside, which is rotatably connected to the support beam 1 via the bearing.

[0056] Several rolling element supports 22 are evenly distributed around the hub 21.

[0057] Several rollers 23 are rotatably mounted on the roller support 22 in a one-to-one correspondence, and can rotate relative to the roller support 22. The several rollers 23 form the outer circumferential wheel surface of the roller 2.

[0058] The axes of all rollers 23 are inclined to the same side along the circumference of the roller 2, and the included angles between the axes of all adjacent rollers 23 are equal; and the axes of all rollers 23 are perpendicular to the axis of the roller 2.

[0059] This composite roller can move forward and backward as a whole, and can also move laterally left and right through the roller 23. Using this composite roller can effectively drive the water hose to move forward, backward, left and right, adapting to the turning of the water hose during the movement process, making the water hose move more smoothly.

[0060] Furthermore, the roller 23 has a conical structure, with its outer diameter gradually decreasing from one end to the other along the axis. Specifically, the outer diameter of the roller 23 gradually decreases from the end connected to the roller support 22 to the other end along the axis; that is, the end of the roller 23 connected to the roller support 22 is the large-diameter end, and the end of the roller 23 away from the roller support 22 is the small-diameter end. The roller 23 has an inwardly facing groove 231 at the end closest to the roller support 22 (i.e., the large-diameter end). In the composite roller, adjacent rollers 23 are fitted end-to-end with a clearance fit, and the small-diameter end of the roller 23 is fitted into the groove 231 of the large-diameter end, with a gap between them. The roller support 22 is also connected to the roller 23 within the groove 231.

[0061] The composite roller can adapt well to the transfer of water hoses in different scenarios. It is not easy to get stuck by stones, and it is less likely to tip over, making it more stable and convenient to use.

[0062] In summary, the water hose transfer auxiliary device of this utility model, which is equipped with a supporting beam 1, a pipe clamp assembly 3, and rollers 2 working together, has a simple structure and is easy to use. The pipe clamp assembly 3 can quickly clamp the water hose to assist in its movement. In particular, after the water hose is filled with water, it can effectively reduce the labor intensity of firefighters dragging the water hose, making the water hose movement lighter and faster, and effectively improving the efficiency of water hose movement and fire fighting operations. The device has a simple and compact structure, strong applicability, and is quick to install and disassemble, and convenient to store and transport.
