Description

Technical Field

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

[0002] Fire hoses are pipes used in fire-fighting equipment to transport high-pressure water and flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer surface wrapped with linen fabric, while advanced fire hoses are made of polymer materials such as polyurethane. Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spray pressure, thereby improving the fire extinguishing effect.

[0003] When not in use, fire hoses are usually stored in a rolled-up manner or installed in a fire hose box. The work of rolling up fire hoses is usually done by the user. After each use, the fire hose is stretched flat and kept flat, then folded in half, and rolled up from the folded part to the joint until the fire hose is rolled into a round shape. However, this method is prone to the fire hose not being tight after rolling, and it is easy to loosen after a period of time, affecting the efficiency of unfolding it next time.

[0004] Therefore, we propose a fire hose reeling device. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a fire hose reeling device to improve these issues.

[0006] The technical solution of this utility model is:

[0007] A fire hose reel device includes a stabilizing base and a reel column that rotates on top of the stabilizing base. One side of the reel column is set as a plane, and an insertion port is provided at the top of the plane along the length direction of the reel column. A clamping block for holding the folded part of the fire hose is provided in the insertion port. Two reel columns that form a triangle with the reel column are fixedly connected to the top surface of the stabilizing base. Limiting openings are provided on the surface of the reel columns.

[0008] In a further technical solution, the retractable post includes a mounting base fixedly installed on the top surface of the stabilizing seat. A first clamping plate is fixedly connected to the top of the mounting base. A second clamping plate, hinged to the mounting base, is provided on the opposite side of the first clamping plate. The limiting opening is located between the first and second clamping plates. A snap-fit ​​assembly is provided between the top of the second clamping plate and the first clamping plate. Support frames, arranged along the length direction of the limiting opening, are fixedly connected to the opposite sides of both the first and second clamping plates. Rollers are mounted on the surface of each support frame, and the rollers are vertically arranged on the first and second clamping plates via the support frames. On the plate, the limiting port is located between the first and second clamping plates, which can play a stable limiting role for the fire hose, ensuring that the hose stays in a specific position during the winding process and does not shake or deviate at will. At the same time, the support frame set along the length of the limiting port and the rollers installed on its surface provide a guiding role for the hose, so that the hose can be wound onto the winding post in a predetermined direction. Furthermore, the circumferential surface of the rollers is placed horizontally, which can better contact the flat hose, reduce the friction of the hose during the movement, ensure the smooth winding of the hose, and prevent the hose from being damaged due to uneven force or excessive friction.

[0009] In a further technical solution, the snap-fit ​​assembly includes a snap-fit ​​opening at the top of the first clamping plate, a plug fixedly connected to the top of the side wall of the second clamping plate, a symmetrical slot on the side wall of the plug, and sliding openings on both sides of the inner wall of the snap-fit ​​opening. A pin is inserted into the inner wall of the sliding opening, one end of the pin is connected to a pull ring on the outside of the first clamping plate, and the end of the pin away from the pull ring is fitted and snap-fitted into the slot. A compression cavity with a diameter larger than the sliding opening diameter is formed inside the sliding opening. A second spring is sleeved on the outer surface of the pin on the inner wall of the compression cavity, and one end of the second spring is fixedly connected to the end of the compression cavity. The end is fixedly connected to the sliding mouth. When using this snap-fit ​​assembly, the fingers support the pull ring and pull it outwards towards the first clamp plate, so that the two inserts are relatively far apart. Then, the insert is placed in the snap-fit, and the pull ring is released, so that the insert is inserted into the slot and the insert is limited. During the process, the second spring is in a state of contraction and release of elastic force, so that the insert has an elastic reset effect, improving the convenience of use. Secondly, during the process of the winding column rotating to wind up the fire hose, this limiting structure can prevent the hose from coming off the limiting port or being displaced, ensuring that the hose is always wound onto the winding column according to the predetermined path, ensuring the smooth progress of the winding process, and allowing the hose to be evenly and tightly wound on the surface of the winding column.

[0010] In a further technical solution, an adjustment port is provided on one side of the socket, and one side of the pressure block is inserted into the inner wall of the adjustment port. The inner wall of the adjustment port and the side of the pressure block are fixedly connected with equidistant first springs. When the pressure block contacts the fire hose, the thickness of the fire hose will push the pressure block into the adjustment port to squeeze the first spring. At the same time, it will also be pushed by the restoring elasticity of the first spring, so that the surface of the fire hose placed in the socket is clamped.

[0011] In a further technical solution, the opening side of the socket is connected to a limiting groove formed on the take-up column, and the limiting groove and the socket are comma-shaped.

[0012] In a further technical solution, the folded side of the fire hose can be bent and placed in the spigot, which makes the fire hose more stable during the rotation of the retractor.

[0013] The beneficial effects of this utility model are:

[0014] To maintain the tightness of the fire hose during rapid winding, the folded end is inserted from top to bottom through the spigot, allowing the edge of the folded end to bend and fit into the limiting groove. During the downward pressing process, the pressure block is elastically supported and clamped by the first spring, holding the initial winding end of the fire hose. Then, the fire hose away from the folded end is inserted into the limiting port. As the winding column rotates and winds, the fire hose in the limiting port is pressed down by symmetrical rollers to maintain a rolling output state, ensuring that the wound fire hose remains flat. This ensures that the fire hose remains flat even when wound on the surface of the winding column. At the end of the winding, the two connecting ends are placed on the side of the winding column away from the winding column. Throughout the static process, the fire hose is kept flat by surface limiting, effectively preventing loose winding. Attached Figure Description

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example:

[0024] like Figures 1-5 As shown in the embodiment of this utility model, a fire hose reel includes a stabilizing base 1 and a reeling column 2 that rotates on top of the stabilizing base 1. Figure 2 The top surface of the stabilizer 1 shown has a motor with a shaft embedded in it. The bottom surface of the take-up column 2 can be welded to the shaft or a snap-fit ​​can be directly made to engage with the shaft. One side of the take-up column 2 is set as a plane, and the top of this plane has an insertion port 4 set along the length of the take-up column 2. The length of the insertion port 4 is generally consistent with the flat width of the actual fire hose. A pressure block 5 with a clamping point for holding the fold of the fire hose is set in the insertion port 4. An adjustment port 10 is opened on one side of the insertion port 4. One side of the pressure block 5 is inserted into the inner wall of the adjustment port 10. The inner wall of the adjustment port 10 and the side of the pressure block 5 are fixedly connected with equidistant first springs 11. When the pressure block 5 contacts the fire hose, the adjustment port 10 is adjusted to hold the fire hose. When the fire hose is in operation, the thickness of the fire hose will push the pressure block 5 into the adjustment port 10 to compress the first spring 11. At the same time, it will also be pushed by the return elasticity of the first spring 11, so that the surface of the fire hose placed in the socket 4 is clamped. One side of the opening of the socket 4 is connected to the limiting groove 3 opened on the winding column 2. The limiting groove 3 and the socket 4 are comma-shaped, which makes it convenient to bend the folded side of the fire hose into the socket 4, so that the winding column 2 gives the fire hose a more stable effect during rotation. The top surface of the stabilizing seat 1 is fixedly connected to two winding columns 6 that form a triangular distribution with the winding column 2. The surface of the winding column 6 is provided with a limiting port 7.

[0025] In another embodiment, such as Figure 4As shown, the retractable post 6 includes a mounting base 61 fixedly installed on the top surface of the stabilizing base 1. A first clamping plate 62 is fixedly connected to the top of the mounting base 61. A second clamping plate 63, which is hinged to the mounting base 61, is provided on the opposite side of the first clamping plate 62. A limiting opening 7 is located between the first clamping plate 62 and the second clamping plate 63. A snap-fit ​​assembly is provided between the top of the second clamping plate 63 and the first clamping plate 62. Support frames 8, which are arranged along the length direction of the limiting opening 7, are fixedly connected to the opposite sides of the first clamping plate 62 and the second clamping plate 63. Rollers 9 are installed on the surface of each support frame 8, and the rollers 9 are vertically arranged on the first clamping plate 62 and the second clamping plate 63 through the support frame 8.

[0026] The limiting port 7 is located between the first clamping plate 62 and the second clamping plate 63, which can play a stable limiting role for the fire hose, ensuring that the hose stays in a specific position during the winding process and does not shake or deviate at will. At the same time, the support frame 8 and the rollers 9 installed on its surface along the length of the limiting port 7 provide a guiding role for the hose, so that the hose can be wound onto the winding post 2 in a predetermined direction. Furthermore, the circumferential surface of the rollers 9 is placed horizontally, which can better contact the flat hose, reduce the friction of the hose during the movement, ensure the smooth winding of the hose, and prevent the hose from being damaged due to uneven force or excessive friction.

[0027] In another embodiment, such as Figure 1 , Figure 4 , Figure 5 As shown, the snap-fit ​​assembly includes a snap-fit ​​opening 12 at the top of the first clamping plate 62, a plug block 13 fixedly connected to the top of the side wall of the second clamping plate 63, a symmetrical slot 14 opened on the side wall of the plug block 13, a sliding opening 15 opened on both sides of the inner wall of the snap-fit ​​opening 12, a plug post 16 inserted into the inner wall of the sliding opening 15, a pull ring 17 connected to one end of the plug post 16 to the outside of the first clamping plate 62, and the end of the plug post 16 away from the pull ring 17 being adapted to snap-fit ​​with the slot 14, a compression cavity 18 with a diameter larger than the diameter of the sliding opening 15 is opened in the sliding opening 15, a second spring 19 sleeved on the outer surface of the plug post 16 is provided on the inner wall of the compression cavity 18, and one end of the second spring 19 is fixedly connected to the end of the compression cavity 18, and the other end of the second spring 19 is fixedly connected to the sliding opening 15.

[0028] When using this snap-fit ​​assembly, hold the pull ring 17 with your finger and pull it outwards towards the first clamp 62, so that the two inserts 16 are relatively far apart. Then place the insert 13 into the slot 12 and release the pull ring 17, so that the insert 16 is inserted into the slot 14 and the insert 13 is limited. During the process, the second spring 19 is in a state of contraction and release of elastic force, so that the insert 16 has an elastic reset effect, improving the ease of use. Secondly, during the process of the winding column 2 rotating to wind up the fire hose, this limiting structure can prevent the hose from coming off the limiting port 7 or from being displaced, ensuring that the hose is always wound onto the winding column 2 along the predetermined path, ensuring the smooth progress of the winding process, and allowing the hose to be evenly and tightly wound on the surface of the winding column 2.

[0029] When the device is used to wind up the fire hose: the worker places the two ends of the fire hose crosswise, then folds it in half. Next, the folded end is inserted from top to bottom into the insertion slot 4, bending the edge of the folded end into the limiting groove 3. During this process, the pressure block 5, due to the pressure of the fire hose's thickness, is pushed into the adjusting port 10, thereby compressing the first spring 11 and generating a restoring elastic push, causing the pressure block 5 to tightly clamp the initial winding end of the fire hose, ensuring the initial end of the hose is securely on the winding post 2. Then, the worker holds the pull ring 17 and pulls it outwards towards the first clamping plate 62, causing the two insertion posts 16 to move away from each other, opening the second clamping plate 63. Finally, the fire hose, away from the folded end, is inserted into the first clamping plate. In the limiting opening 7 formed by the opposing plates 62 and 63, the pull ring 17 is released, and the insert post 16, under the elastic reset action of the second spring 19, is inserted into the slot 14 to limit the insertion block 13, thereby clamping the fire hose with the first clamp plate 62 and the second clamp plate 63 and limiting the middle section of the hose. At this time, the support frame 8 and the rollers 9 installed on its surface along the length direction of the limiting opening 7 begin to function, and the drive motor makes the winding post 2 start to rotate. As the winding post 2 rotates, the part of the fire hose in the limiting opening 7 is pressed by the symmetrical rollers 9, maintaining a rollable output state, so that the wound fire hose is always flat and wound around the surface of the winding post 2 according to a predetermined path.

[0030] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
