Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fast-winding water hose device for a fire truck. Background Art

[0002] The fire hose is an important part of the fire fighting system. It is mainly used to quickly supply water when a fire occurs to help firefighters control and extinguish the fire. The design and installation of the fire hose must comply with the corresponding fire safety regulations to ensure that it can play its due role at critical moments. The hose needs to be reeled after each use for easy carrying and reuse.

[0003] In the prior art, firefighters will manually organize and reel the used hoses after extinguishing a fire. However, since the firefighters have already consumed a lot of physical energy during the fire extinguishing process, they cannot reel the hoses quickly, resulting in low reeling efficiency and increasing the physical energy consumption of the firefighters. For this reason, a quick hose reeling device for fire trucks is designed.

[0004] Through the patent search of the State Intellectual Property Office, several types of fire hose reeling structures or devices were retrieved, such as: CN202421049542.3 A fire hose automatic reeling device, which mainly solves the problem of accidental unwinding of the hose during the reeling process; CN202420465418.9 A fire hose reeling device, which mainly fixes the fire hose reeling device on a certain structure, saving a certain amount of manpower; CN202323410061.9 A lightweight self-propelled urban fire hose electric reel, which mainly has the equipment that can automatically walk and automatically stop after the hose is fully rolled up. The entire reeling process does not require manual intervention and is suitable for standardized and flat fire-fighting sites such as cities. None of the above patent structures can provide a structure that can both quickly reel the hose and automatically separate the hose from the reeling device.

[0005] Therefore, a fire truck fast reeling hose device is needed that can quickly reel the hose and automatically separate the hose from the reeling device. Utility Model Content

Under the action of the two blocking bars 7, the water hose is limited during the winding process so that the water hose will not slip out of the semicircular rod 203. One end of the water hose is clamped by the two semicircular rods 203 to realize the winding of the water hose.

[0037] Example 3

[0038] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6, the extrusion mechanism 3 is further described. The extrusion mechanism 3 includes a second vertical plate 301, one side of the second vertical plate 301 is rotatably connected to a rotating roller 302, a rectangular hole is opened on the second vertical plate 301, a screw block 305 is slidably connected in the rectangular hole, and an adjusting roller 306 is rotatably connected to the screw block 305 on the side close to the rotating roller 302; a second screw rod 304 is rotatably connected to the rectangular hole, and the second screw rod 304 is threadedly passed through the screw block 305, and a threaded hole adapted for the second screw rod 304 is opened on the screw block 305, and the top of the screw block 305 passes through the second vertical plate 301 and is fixedly connected to the third handle 303, and the top of the second vertical plate 301 is opened with a circular hole adapted for the screw block 305. Rotating the third handle 303 can drive the second screw rod 304 to rotate, and further drive the screw block 305 passed through by the second screw rod 304 to move on the second screw rod 304, and then drive the adjusting roller 306 on the screw block 305 to move. When the distance between the adjusting roller 306 and the rotating roller 302 is less than the thickness of the water hose, the water hose can be squeezed to discharge the water in the water hose for easy winding.

[0039] Working principle: A quick water hose reeling device for fire trucks. When in use, according to the material of the water hose, the third handle 303 is turned so that the distance between the adjusting roller 306 and the rotating roller 302 is appropriate, which is convenient for draining the water in the water hose and limiting the position of the water hose. When one end of the water hose passes through the squeezing mechanism 3 and is placed between the two semicircular rods 203, the second handle 204 is turned to rotate the turntable 202 to realize the reeling of the water hose. Under the action of the two blocking rods 7, the water hose is limited during the reeling process so that the water hose will not slip out of the semicircular rods 203. When the water hose is reeled, when it is necessary to separate the water hose from the device, the first handle 601 is turned so that the L-shaped placement plate 5 moves away from the reeling. When the L-shaped placing plate 5 is reset after completion, the baffle 7 becomes vertical with the cooperation of the U-shaped rod 504 and the inclined slot 702, and continues to limit the water hose during the winding process.
