Description

Technical Field

[0001] This utility model belongs to the field of fire protection technology, specifically relating to an automatic fire hose winding and coiling device. Background Technology

[0002] Fire safety is of paramount importance in grain storage, and fire hoses, as key fire-fighting equipment, directly affect emergency response efficiency through proper storage and management after use.

[0003] As a crucial aspect of safe production in grain depots, strengthening fire safety management is of paramount importance. To enhance emergency response and coordination capabilities, quickly unwinding fire hoses and connecting them to fire hydrants is an essential training subject during emergency drills and volunteer firefighter training. However, the unwinding fire hoses are often manually coiled up for storage. This traditional manual operation not only consumes a significant amount of manpower and time but is also inefficient and fails to meet the demands of efficient management in modern grain depots. Furthermore, the coiling process is time-consuming and labor-intensive, and the hoses are often not neatly or tightly coiled, thus taking up too much training time and manpower. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides an automatic fire hose winding and coiling device, including a frame, a tension adjustment device and a deviation correction device.

[0005] A hook is fixedly connected to the side surface of the frame, a low-speed DC motor is fixedly connected to the side surface of the frame, a threaded shaft is fixedly connected to the output end of the low-speed DC motor, a first collection tray is fixedly connected to the side surface of the threaded shaft, and a second collection tray is threadedly connected to the side surface of the threaded shaft.

[0006] The tension adjustment device includes a threaded rod, a sleeve threaded to the side surface of the threaded rod, and a guide roller rotatably connected to the side surface of the sleeve. The correction device includes a first correction wheel and a second correction wheel movably connected to the upper surface of the frame.

[0007] Through the above technical solution, by setting hooks, the entire device can be easily suspended on the frame of an electric tricycle. A low-speed DC motor drives the threaded shaft to rotate, thereby enabling the fire hose to be wound up. The first collecting tray and the movable second collecting tray are used to limit the fire hose during winding, making it more neat after winding. The adjustable second collecting tray and the movable first straightening wheel can limit fire hoses of different diameters, improving the applicability of the device. The tension adjustment device can adjust the tension of the fire hose during winding by adjusting the threaded rod, changing the position of the sleeve and the guide roller, thereby ensuring tight and neat winding. The first and second straightening wheels of the straightening device can correct the conveying direction of the fire hose in real time, preventing the hose from deviating or stacking disorderly during winding, effectively improving the winding quality.

[0008] The present invention is further configured such that a mounting bracket is fixedly connected to the side surface of the frame, a hydraulic push rod is fixedly connected to the side surface of the mounting bracket, a push plate is fixedly connected to the output end of the hydraulic push rod, and a position sensor is fixedly connected to the side surface of the push plate.

[0009] Through the above technical solution, the hydraulic push rod can drive the push plate to perform telescopic movement. After the fire hose is wound, the coiled hose can be pushed out from the threaded shaft, which is convenient for subsequent use and storage, reducing manual operation. After the position sensor is turned on, it can monitor the position of the push plate at the orifice 61.

[0010] The present invention is further configured such that a fire hose is movably connected to the side surface of the threaded shaft, the side surface of the guide roller is in contact with the fire hose, and the two sides of the fire hose are in contact with the first straightening wheel and the second straightening wheel, respectively.

[0011] Through the above technical solution, the guide roller is used to adjust the tension of the fire hose and guide the movement of the fire hose during winding.

[0012] The present invention is further configured such that an installation block is fixedly connected to the upper surface of the frame by bolts, the upper surface of the installation block is rotatably connected to the threaded rod through it, and the side surface of the sleeve is in contact with the inner side wall of the installation block.

[0013] Through the above technical solution, the side surface of the sleeve contacts the inner wall of the mounting block, thereby limiting the vertical displacement of the sleeve.

[0014] The present invention is further configured such that a groove is provided on the upper surface of the frame, a lead screw is rotatably connected to the inner side wall of the groove, and a displacement block is threadedly connected to the side surface of the lead screw.

[0015] The above technical solution allows the displacement block to be displaced by rotating the lead screw, which in turn causes the mounting rod above and the first correction wheel to be displaced.

[0016] The present invention is further configured such that the side surface of the displacement block contacts the groove, the upper surface of the displacement block is fixedly connected to an installation rod, and the side surface of the installation rod is rotatably connected to the first correction wheel.

[0017] The present invention is further configured such that a mounting column is fixedly connected to the upper surface of the frame, and the side surface of the mounting column is rotatably connected to the second correction wheel.

[0018] The present invention is further configured such that a controller is fixedly connected to the side surface of the frame, and the side surface of the first collection tray is provided with a plurality of holes.

[0019] The beneficial effects of this utility model are as follows:

[0020] A low-speed DC motor drives a threaded shaft to rotate, which in turn can wind up the scattered fire hose. Mechanical winding reduces manual labor and improves winding efficiency. Before winding, the position of the second reel and the first straightening wheel are controlled so that the device can be used to wind up fire hoses of different diameters and make the winding more neat. The guide roller guides the fire hose during winding and can adjust its height, thereby adjusting the tension of the fire hose during winding, so that the fire hose is more tightly wound after winding.

The tricycle provides power to the device. When winding the fire hose 12, firstly, one end of the fire hose 12 is wound around the threaded shaft 5. The second collecting disc 7 is rotatably mounted on the threaded shaft 5. Then, the low-speed DC motor 4 is turned on via controller 3. The low-speed DC motor 4 drives the threaded shaft 5 to rotate, causing the fire hose 12 to wind. The distance between the second straightening wheel 23 and the first straightening wheel 21 can be adjusted to... This device is suitable for fire hoses 12 of various diameters. By rotating the threaded rod 14 to adjust the height of the guide roller 16, the tension of the fire hose 12 during winding can be adjusted, making the winding more neat and tight. After winding is completed, the position sensor 11 is turned on. When the position sensor 11 detects that the push plate 10 is flush with the hole 61, the low-speed DC motor 4 is stopped, the second collecting plate 7 is rotated and removed, and the hydraulic push rod 9 starts the push plate 10 to pass through the hole 61 and push out the wound fire hose 12, completing the winding of the unfurled fire hose 12.
