After the fire rescue is over, firefighters need to spend a lot of time to sort out firefighting equipment, including the fire hoses used for firefighting. Since the hoses contain a lot of liquid after use, if they are not dried in time, the hoses will mold, increase in weight, and are not easy to roll up. Every time firefighters use the hoses, they have to spend a lot of time to dry and roll them up, which is a huge workload. Therefore, it is necessary to design a device that can automatically dry and roll up the fire hoses. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] A fire hose automatic coiling machine, such as Figures 1 to 4 As shown, including:

[0029] The support frame comprises two vertical columns 1, a top rod 2 is arranged at the upper end between the two columns, and a ground beam 3 is arranged at the lower end;

[0030] The crossbeam 6 is installed vertically and slidingly between the two columns of the support frame. Specifically, sliding seats can be respectively provided at both ends of the crossbeam, and the sliding seats can slide and cooperate with the slideways on the columns; a plurality of drying hooks 4 are provided at the lower end of the crossbeam; as an example, a corresponding drying hook can be arranged under each water hose winding device, which can very conveniently hang the water hose.

[0031] The lifting drive device is used to drive the crossbeam to adjust its height, including a transmission chain installed on the inner side of two columns, and a driver 5 that drives the two transmission chains to move synchronously at the same time; as an example, the driver includes a transmission chain drive motor, and the lifting drive device also includes an upper sprocket 7 installed on the upper end of the column, a lower sprocket 8 installed on the lower end, and a transmission shaft 20 that drives the lower sprocket to rotate. The transmission shaft is connected to the extension shaft of the driver through a coupling, and the transmission chain is wound between the upper and lower sprockets. The transmission shaft is driven by the driver to rotate, and the transmission chains on both sides can be synchronized, thereby realizing the position adjustment of the crossbeam driven by the transmission chain in the height direction. A protective cover 22 for shielding the transmission shaft is provided above the above-mentioned ground beam, which has high protection and good safety. The top rod can play a role in strengthening the structural strength of the support frame, and the top rod can also serve as the installation base of the upper sprocket. It only needs to install the two ends of the top rod on the column through the bearing seat respectively, and the upper sprocket is installed on the two ends of the top rod. When the transmission chain moves, the upper sprocket can move with it.

[0032] A plurality of water hose reeling devices include a reel 9 mounted on a crossbeam, a guide mechanism 10 and a limit mechanism 11 are provided on the crossbeam corresponding to the lower portion of the reel; the reel includes a base 12, two positioning rods 13 are provided on the base, and a reeling drive motor 14 for driving the base to rotate is provided on the crossbeam; the guide mechanism includes a guide roller 16 with a guide groove 15 in the middle. In an optional embodiment, the limit mechanism includes a pressure roller 17 arranged corresponding to the guide roller, the pressure roller is arranged on one side of the guide roller through a turning handle 18, and the turning handle presses the pressure roller toward the guide roller. In the specific design, a spring or other components can be used to form a force on the turning handle to tilt or press the pressure roller toward the guide roller. When the water hose is wound onto the reel, the end of the water hose is pressed by the pressure roller, so that the water hose can maintain good stability.

[0033] In addition, the winder can also be provided with a control module, including control switches for controlling the winding drive motor and the driver respectively, and each control switch of the control module is electrically connected to the winding drive motor and the driver respectively, and the control switch can be installed in the distribution box 19, and the distribution box can be installed on the ground beam or the column. When in use, it is only necessary to pass the water hose through the two positioning rods and fold it in half, place the water hose in the guide groove of the guide roller, and let the lower end hang naturally, and then use the control switch to connect the circuit to rotate the winder, so that the water hose can be wound around the outside of the two positioning rods.

[0034] Both the guide roller and the pressure roller are made of nylon rollers. The width of the guide groove is greater than the width of the pressure roller, allowing the pressure roller to be immersed in the guide groove. In actual use, the guide roller is allowed not to be immersed in the guide groove, as long as the water hose can be restricted from being separated from the guide groove. The use of the limiting mechanism can not only limit the end of the water hose to prevent it from moving and shifting, but also ensure that the water hose is always in the guide groove during the water hose winding process, so that the water hose winding process is smooth, the water hose is wound smoothly and tightly, and it will not be loose when taken. It should be noted that since the end of the water hose is restricted in the guide groove, the pressure roller does not need to be too large to press the water hose, as long as the end of the water hose can be prevented from moving at will. In another optional embodiment, the limiting mechanism can adopt a manually actuated or rotated structural design, as long as a certain restriction can be formed on the end of the water hose.

[0035] The invention creates a drying hook on the lower side of the crossbeam to conveniently hang the hose. The hose occupies little space when drying. After drying, it can be rolled up by the winder. It is easy to use, saves manpower, and has high work efficiency. Several groups of hose winding devices are installed on the crossbeam to roll up multiple hoses at the same time. When rolling up the hose, the limit mechanism keeps the hose in the guide groove of the guide roller. The hose winding process is smooth and the rolled hose has high compactness, is not easy to loosen, and is easy to take.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
