Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, specifically to a fire hose collection device. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water, foam, and other flame-retardant liquids. They consist of a braided layer and a lining, and are divided into lined and unlined types. They are widely used for water supply at fire scenes. Fire hoses are connected to other hoses or nozzles via metal joints to extend the water delivery distance or adjust the spray pressure, making them a core water delivery tool at fire scenes.

[0003] After use, fire hoses need to be coiled up. The main reason is to facilitate storage and quick deployment. Coiled fire hoses can be quickly stored, saving space, and can be quickly deployed when needed to ensure unobstructed water supply at the fire scene.

[0004] However, currently, most fire hose coiling is done manually. During the coiling process, the hands need to continuously perform coiling and gripping actions. Gripping is to prevent the coiled fire hose from unraveling and to facilitate subsequent coiling operations. However, after the fire hose is coiled multiple times, the weight of the coiled hose gradually increases, which requires increasing the gripping force of the hands, making the operation difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a fire hose collection device in response to the defects and deficiencies of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fire hose reeling device, comprising a base, a central column rotatably disposed on the upper end face of the base, a recessed locking hole opened on the upper end face of the central column, a limiting column disposed on the upper end face of the central column within the recessed locking hole, a rotating mechanism disposed on the upper end face of the central column for controlling the rotation of the central column on the base, an abutment column slidably disposed on the upper end face of the base, and a control mechanism disposed between the abutment column and the base for driving the abutment column to move closer to or away from the central column on the base.

[0007] A further improvement is that a rotating hole is provided on the upper end face of the base on the outer periphery of the central column, and a rotating bearing is provided between the central column and the base within the rotating hole.

[0008] A further improvement is that the lower end face of the recessed card hole is connected to the rotating hole.

[0009] A further improvement is that the rotating mechanism includes a rotating rod disposed on the upper end face of the central column, a side extension handle disposed on the upper end of the rotating rod, and a drive handle disposed on the side extension handle.

[0010] A further improvement is that the lower end of the drive handle is rotatably mounted on the side extension handle.

[0011] A further improvement is that: a disassembly circular hole is provided on the upper end face of the central column, and a side locking hole is provided on the central column. The side locking hole is connected to the disassembly circular hole, and the side locking device is located at the side end of the disassembly circular hole. The rotating rod is in clearance fit with the disassembly circular hole, and a side locking block is provided on the side end face of the rotating rod. The side locking block is in clearance fit with the side locking hole.

[0012] A further improvement is that the control mechanism includes a control opening on the upper surface of the base, a slidable abutment post located on the base within the control opening, a control screw rotatably mounted on the base within the control opening, the abutment post being threadedly connected to the control screw, one end of the control screw rotating on the base, and the other end passing through the base and located on one side of the base, and the other end of the control screw being equipped with a rotating handwheel.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When it is necessary to coil the fire hose, first spread the fire hose flat on the ground, then fold the hose into two layers, pull the folded part into the recessed opening and hang it on the limiting post. Then, control the central post to rotate on the base through the rotating mechanism, and straighten the uncurled part of the fire hose. At this time, the fire hose gradually curls on the central post as the central post rotates, and because the limiting post hooks the folded part of the fire hose, the fire hose is gradually curled on the central post. When the fire hose is finished curling, drive the abutment post on the base to move closer to the central post through the control mechanism until the abutment post presses against the curled fire hose, preventing the curled fire hose from unraveling. With this coiling method, there is no need to continuously hold the curled fire hose by hand, and the operation is easy.

[0014] Further effects: When it is necessary to control the rotation of the central column on the base, the hand grips the drive handle and moves it circumferentially around the central column as the central axis, in a circular motion. The side extension handle and the rotating rod drive the central column to rotate. By moving the central column clockwise or counterclockwise, the fire hose can be coiled or uncoiled.

[0015] Further benefits: Since the drive handle can rotate on the side extension handle, when the hand holds the drive handle and moves circumferentially around the center post, the drive handle can rotate on the side extension handle, so as to facilitate the drive of the side extension handle and the rotating rod when the hand is holding it.

[0016] Further benefits: When it is necessary to remove the rotating rod, side extension handle, and drive handle from the central column to remove the coiled fire hose upwards from the central column, the rotating rod can be lifted upwards to separate from the disassembly hole and side locking hole. If it is necessary to install the rotating rod, side extension handle, and drive handle on the central column, the side locking block is aligned with the position of the side locking hole, and the rotating rod is inserted into the disassembly hole to achieve the installation of the rotating rod, side extension handle, and drive handle. Due to the setting of the side opening and side locking block, the central column can be rotated when the rotating rod rotates circumferentially, preventing the rotating rod from spinning freely in the disassembly hole.

[0017] Further effect: When it is necessary to control the abutment post to move closer to or further away from the center post, the hand can be used to push the rotating handwheel to drive the control screw to rotate in the forward or reverse direction, thereby driving the abutment post to move closer to or further away from the center post within the control opening. When the control of the rotating handwheel is stopped, the position of the abutment post is fixed by the self-locking effect of the thread. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1 to 5 As shown, the technical solution adopted in this specific embodiment is: a fire hose reeling device, including a base 1, a central column 2 rotatably disposed on the upper end face of the base 1, a recessed locking hole 3 opened on the upper end face of the central column 2, a limiting column 4 disposed on the upper end face of the central column 2 within the recessed locking hole 3, a rotating mechanism disposed on the upper end face of the central column 2 for controlling the rotation of the central column on the base 1, an abutment column 5 slidably disposed on the upper end face of the base 1, and a control mechanism disposed between the abutment column 5 and the base 1 for driving the abutment column 5 to move closer to or away from the central column 2 on the base 1. The recessed opening is eccentrically disposed on the central column 2, with one end extending through the side end face of the central column 2, while the limiting column 4 is disposed on the other end of the recessed opening.

[0027] A rotating hole 6 is provided on the upper end face of the base 1 on the outer periphery of the central column 2. A rotating bearing 7 is provided between the central column 2 and the base 1 within the rotating hole 6. The rotating bearing 7 is installed between the base 1 and the central column 2 within the rotating hole 6 by means of embedding or snapping.

[0028] The lower end face of the recessed locking hole 3 is connected to the rotating hole 6. The horizontal line of the lower end face of the recessed locking hole 3 is lower than the horizontal line of the upper end face of the base 1, so that when the folded part of the fire hose is hung on the limiting post 4, the lower end face of the fire hose abuts against the upper end face of the base 1, thus preventing the center position of the fire hose from being too high after coiling.

[0029] The rotating mechanism includes a rotating rod 8 disposed on the upper end face of the central column 2, a side extension handle 9 disposed on the upper end of the rotating rod 8, and a drive handle 10 disposed on the side extension handle 9. Figure 2 As shown, the handle is shaped like a "7" between the rotating handle and the side extension handle 9. The rotating structure can also have a rotating handwheel 16 directly installed at the upper end of the rotating rod 8, or for convenience, a rotating motor can be installed directly between the base 1 and the center column 2 or the upper end of the rotating rod 8, with the fixed end of the rotating motor connected to the base 1 via a bracket, and the output end connected to the center column 2 or the rotating rod 8.

[0030] The lower end of the drive handle 10 is rotatably mounted on the side extension handle 9. A through hole is provided on the side extension handle 9, and an insertion rod is provided on the lower end face of the drive handle 10. A limiting plate is provided on the lower end face of the insertion rod. The diameter of the limiting plate is larger than the diameter of the through hole. The through hole and the insertion rod are clearance-fitted. The upper end of the insertion rod is welded, glued, or integrally formed with the drive handle 10. During installation, the insertion rod is first inserted from the position of the through hole, and then the limiting plate is connected to the lower end of the insertion rod by welding or gluing, thereby preventing the insertion rod from slipping off the through hole and realizing the rotation of the drive handle 10 on the side extension handle 9.

[0031] The upper end face of the central column 2 is provided with a disassembly circular hole 11. The central column 2 is provided with a side locking hole 12, which communicates with the disassembly circular hole 11. The side locking device is located at the side end of the disassembly circular hole 11. The rotating rod 8 is in clearance fit with the disassembly circular hole 11. A side locking block 13 is provided on the side end face of the rotating rod 8, and the side locking block 13 is in clearance fit with the side locking hole 12. The disassembly circular hole 11 and the side locking hole 12 are arranged as follows... Figures 2 to 5 As shown.

[0032] The control mechanism includes a control opening 14 on the upper surface of the base 1. A slidable abutment post 5 is located on the base 1 within the control opening 14. A control screw 15 is rotatably mounted on the base 1 within the control opening 14. The abutment post 5 is threadedly connected to the control screw 15. One end of the control screw 15 rotates on the base 1, and the other end passes through the base 1 and is located on one side of the base 1. A handwheel 16 is provided at the other end of the control screw 15. A bearing can be provided between the other end of the control screw 15 and the base 1 for rotational support.

[0033] The working principle of this utility model is as follows: When it is necessary to coil the fire hose, first lay the fire hose flat on the ground, then fold the hose into two layers, pull the folded part into the recessed opening and hang it on the limiting post 4. Then, hold the drive handle 10 and move it circumferentially around the central post 2 as the central axis, in a circular motion. This is done by the side extension handle 9 and the rotating rod 8 to drive the central post 2 to rotate, straightening the uncoiled part of the fire hose. At this time, the fire hose rotates with the central post 2, and because the limiting post 4 hooks the fire hose... The fire hose is gradually rolled up on the central column 2 by folding the waterproof hose in half. After the fire hose is rolled up, the handwheel 16 is pushed to rotate the control screw 15 in the forward or reverse direction, thereby driving the abutment column 5 on the base 1 to move closer to the central column 2 until the abutment column 5 is pressed against the rolled fire hose to complete the storage, preventing the rolled fire hose from unraveling. This rolling method eliminates the need to continuously hold the rolled fire hose by hand, making the operation simple.

[0034] Since the drive handle 10 can rotate on the side extension handle 9, when the hand holds the drive handle 10 and moves circumferentially around the central column 2, the drive handle 10 can rotate on the side extension handle 9 so as to drive the side extension handle 9 and the rotating rod 8 when the hand holds it.

[0035] When it is necessary to remove the rotating rod 8, side extension handle 9, and drive handle 10 from the central column 2 so that the coiled fire hose can be taken out of the central column 2, the rotating rod 8 can be separated from the disassembly hole 11 and the side locking hole 12 by lifting it upwards. If it is necessary to install the rotating rod 8, side extension handle 9, and drive handle 10 on the central column 2, the side locking block 13 is aligned with the position of the side locking hole 12, and the rotating rod 8 is inserted into the disassembly hole 11, thereby realizing the installation of the rotating rod 8, side extension handle 9, and drive handle 10. Due to the setting of the side opening and the side locking block 13, the central column 2 can be rotated when the rotating rod 8 rotates in a circumferential direction, and the rotating rod 8 will not make free rotation in the disassembly hole 11.

[0036] When control of the rotating handwheel 16 is stopped, the position of the abutment post 5 is fixed by the self-locking effect of the thread.
