Description

Technical Field

[0001] The utility model relates to the field of hose storage, in particular to a hose retracting and releasing device suitable for retracting and releasing fire hoses. Background Art

[0002] A hose is a flexible pipe that transports water or foam, and is widely used in firefighting, agriculture, gardening, construction, and industry. There are many types of hoses, which can be classified according to their length, material, and other properties. When buying a hose, you need to consider your actual needs and the area of ​​use to choose the appropriate length; at the same time, you need to consider the water pressure. If the water flow is large, you can choose a hose with a larger diameter. The choice of material needs to be based on usage habits, etc. If you want long-term durability, you can choose rubber or TPR material.

[0003] In the field of firefighting, fire hoses are commonly used tools. When not in use, the hose is rolled into a coil. When in use, the hose is pulled open and connected to a fire hydrant or fire truck. After the fire is extinguished, the fire hose must be slowly rolled back manually, which is slow and inefficient. In addition, the entire roll of hose must be held in the hand. As the hose reel increases, it becomes heavier, which is time-consuming and labor-intensive and increases the labor intensity of the operator.

[0004] The prior art with patent publication number CN217350274U discloses a retractable automatic fire hose reel trolley, which is provided with side panels, a front bracket, an upper bracket, a telescopic push rod, a hose locking device and a reeling device, etc., and a clamping claw locking mechanism is provided at the outer end of the rotating shaft, and a quick-change clamping claw is provided at the inner end of the rotating shaft. This retractable automatic fire hose reel trolley can easily clamp and release the hose joint through the hose joint clamping mechanism. Due to the principle of joint clamping, a hose can only be rolled into one circle, and during the rotation process, there is a risk that the clamping claw will be wrapped around the hose reel due to the deviation of the hose, resulting in the failure of the entire reeling.

[0034] Embodiment 1

[0035] like Figure 1 As shown, a hose retracting and releasing device is particularly suitable for reeling in fire-fighting pipeline hoses, comprising a base 1 and a belt pressing assembly, a winding assembly and a belt-following mechanism arranged on the base 1;

[0036] The belt pressing assembly includes a support column 2 fixedly connected to one side of the top of the base 1, an extension portion is provided on the support column 2, and a connecting rod 3 is inserted and connected to the extension portion. A pressing portion is provided at the bottom of the connecting rod 3, and a spring 4 is provided between the pressing portion and the extension portion (see Figure 2 );

[0037] Winding assembly: comprising a column 7 and a round roller 8, both ends of the round roller 8 are respectively mounted on a column 7, that is, the top of the column 7 is movably connected with the round roller 8;

[0038] The lower pressing part is located above the round roller 8;

[0039] The belt-following mechanism comprises a baffle 12 arranged on the base 1, the number of the baffles 12 is two, a slide bar 13 is arranged between the baffles 12, and a belt presser is arranged on the slide bar 13; the belt-following mechanism is arranged in front of the winding assembly.

[0040] This embodiment uses a support column 2, a connecting rod 3, a spring 4, and a downward pressing part arranged on a base 1. When in use, the downward pressing part is located on the round roller 8. During the process of the round roller 8 being retracted, the downward pressing part will press on the water hose. With the cooperation of the belt-following mechanism, during the process of unwinding the water hose, the water hose will not be accumulated at a certain place of the round roller 8, thereby improving the neatness during the rewinding or unwinding process and facilitating use.

[0041] In a preferred embodiment, the pressing part includes a fixed plate 5 and an arc plate 6, wherein the fixed plate 5 is arranged at the bottom of the connecting rod 3, and the top of the arc plate 6 is connected to the fixed plate 5. Since the arc plate 6 is arc-shaped, if it is directly connected to the connecting rod 3, there may be a loose connection at the connection. The fixed plate 5 is provided, and the connection area between the fixed plate 5 and the arc plate 6 is large, and even the fixed plate 5 and the arc plate 6 can be integrally formed. Therefore, the connection strength between the fixed plate 5 and the arc plate 6 is high. Moreover, because the fixed plate 5 is provided, compared with a single arc plate 6, the thickness of the connection is increased, and the connection is more stable.

[0042] In a preferred embodiment, two limit plates 9 are provided on the round roller 8, and the winding area is between the two limit plates 9. The limit plate 9 can be a round plate. Compared with the prior art, it is no longer the width of the water hose that is wound, but an area. The width of the winding area can be 5-10 times the width of the water hose. During the winding process, the water hose can move left and right without worrying about the water hose running off the track, thereby improving the winding efficiency. In addition, after winding a roll of water hose, it can be pushed to one side of the round roller 8 and another roll of water hose can continue to be wound, and the device utilization rate is high.

[0043] In a preferred embodiment, if Figure 4 As shown, a slot 10 is provided on the round roller 8, and the slot 10 is located in the winding area. By providing the slot 10, the hose joint can be fixed for a short time. When in use, the hose head is inserted into the slot 10, and after the round roller 8 rotates, the hose head can form an angle with the hose body, and the hose head is not easy to fall out of the slot 10. When winding the second or third circle of the hose, the hose head is covered by the hose, and the hose can be wound with confidence, which is highly practical.

[0044] In a preferred embodiment, a rotating handle 11 is provided at one end of the round roller 8; the rotating handle 11 includes a connecting portion, an intermediate plate and a cylindrical contact portion; the connecting portion is fixed to one end of the round roller 8, and the intermediate plate is provided between the connecting portion and the cylindrical contact portion.

[0045] In a preferred embodiment, see Figure 3The belt press includes a round tube 14, a connecting column 15 and a fixing seat 16. A belt pressing roller 17 is arranged on the fixing seat 16. A belt pressing space is formed between the belt pressing roller 17 and the connecting column 15. The round tube 14 is sleeved on the slide bar 13. This embodiment provides a specific form of a belt press. Through the cooperation of the belt pressing roller 17 and the connecting column 15, when the water hose passes through the belt pressing space, the belt pressing roller 17 squeezes the water hose, and the residual water inside the water hose can be squeezed out, making it more convenient to reel it. During the reeling process, the round tube 14 will slide left and right with the water hose to facilitate the unwinding of the water hose on the round roller 8.

[0046] In a preferred embodiment, a fixing seat 16 is provided on both sides of the top of the connecting column 15, and a through hole or a groove is provided on the top of the fixing seat 16; a rotating shaft is provided at both ends of the belt holding roller 17, and the end of the rotating shaft is provided in the through hole or the groove. This structure is in the form of the round tube 14, and the water hose can be angularly offset during use. That is, the connecting column 15 can rotate under the action of the round tube 14, and the belt holding roller 17 can also rotate, so as to avoid the situation that the water hose gets stuck during the winding or unwinding process after the entire belt-holding mechanism is fixed. Therefore, the use of this structure can improve the water hose's ability to get out of trouble to a certain extent.

[0047] In a preferred embodiment, the cross section of the belt holding roller 17 is circular, and the cross section area of ​​the middle part of the belt holding roller 17 is smaller than the cross sections of the two ends of the belt holding roller 17. The belt holding roller 17 is small in the middle and large at both ends, and the belt space presents a structure of wide in the middle and narrow at both ends, so as to prevent the water hose from getting tangled or folded during the pulling process.

[0048] In a preferred embodiment, a thread is provided on the top of the connecting rod 3, and the top of the connecting rod 3 cooperates with a nut (the nut is not shown in the figure). Considering that in the early stage of winding, it is necessary to initially fix the hose head and other operations, if the arc plate 6 is always against the round roller 8 at this time, it is not convenient to operate. Therefore, at some times, the arc plate 6 can be suspended in the air, and then the fixing problem of the connecting rod 3 needs to be considered. The connecting rod 3 can be fixed by the nut after the arc plate 6 has a certain height, thereby achieving the effect of fixing the height of the arc plate 6.

[0049] In a preferred embodiment, the base 1 includes a rectangular plate and a running mechanism arranged at the bottom of the rectangular plate, and the running mechanism is installed at the four corners of the rectangular plate; the running mechanism is a universal wheel.

The arc plate 6 is located at the top of a round roller 8. During the process of the round roller 8 being retracted, the arc plate 6 will press on the top of the round roller 8 or the hose. With the cooperation of the belt-following mechanism, the hose will not be piled up at a certain place of the round roller 8, thereby improving the neatness during the rewinding process and facilitating the next use of the hose. At the same time, through the baffle 12, the slide bar 13, the round tube 14, the connecting column 15, the fixing seat 16, and the belt-pressing roller 17 arranged on the base 1, the hose can pass through the bottom of the belt-pressing roller 17 during use and be inserted into a slot 10 on one side of the round roller 8. During the rewinding process, the round tube 14 will slide the hose on the top left and right to facilitate the rewinding of the hose on the round roller 8, and the belt-pressing roller 17 will also press out the residual water inside the fire-fighting pipeline (water hose), making it more convenient to rewind it. At the same time, a universal wheel is provided to facilitate its movement, thereby improving the convenience during use.
