Description

Technical Field

[0001] This utility model relates to a fire hose preparation device, and in particular to a hand-cranked and electric dual-mode shoulder-mounted hose reel. Background Technology

[0002] Fire hoses are key equipment in fire fighting and emergency rescue. The quick handling and storage of fire hoses after use directly affects the efficiency of fire fighting operations and the service life of the equipment. At present, fire hose reels are commonly used in the fire fighting field to assist firefighters in completing the hose reeling work. Although such equipment can reduce the intensity of manual handling to a certain extent, it has obvious limitations in complex and special scenarios. In scenarios such as forest fires and rescue operations in remote mountainous areas, firefighters need to carry equipment on foot through rugged mountain roads and complex terrain. Most existing hose reels are fixed or bulky and heavy portable structures, lacking designs adapted for human carrying, making it difficult for firefighters to carry them conveniently during their journeys. At the same time, the driving methods of existing hose reels are relatively simple. Some only support hand-cranked operation, which is time-consuming and laborious when winding long hoses. Although some support electric operation, the overall structure and carrying function are poorly adapted, failing to meet the needs of efficient winding in complex field environments. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a hand-cranked and electric dual-mode shoulder-mounted hose reel.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A dual-mode (hand-cranked and electric) shoulder-mounted hose reel includes a reel and a shoulder frame. A fixed frame is hinged to the lower end of the shoulder frame. The reel is mounted on the fixed frame via a first rotating shaft. A reeling rod is mounted on one side of the reel, and a driven gear that rotates synchronously with the reel is mounted on the other side. A drive gear that meshes with the driven gear is mounted on the fixed frame via a second rotating shaft. A drive rod for connecting to a handheld motor or hand crank is mounted on the second rotating shaft.

[0005] The mounting frame is installed on the fixed frame, and the winding wheel, driven gear, and driving gear are mounted on the mounting frame.

[0006] The mounting bracket is equipped with a first bearing via a first fixed seat. The first fixed seat is fixedly connected to the outer ring of the first bearing, and the first rotating shaft passes through the inner ring of the first bearing.

[0007] The mounting bracket has a second bearing and a second rotating shaft mounted on it via a second fixed seat. The second fixed seat is fixedly connected to the outer ring of the second bearing, and the shaft passes through the inner ring of the second bearing.

[0008] The drive rod has an insertion hole at its center.

[0009] The lower end of the shoulder strap is provided with a first limiting part and a second limiting part on both sides of the hinge position.

[0010] The diameter of the driving gear is smaller than the diameter of the driven gear.

[0011] The lower end of the shoulder rack is equipped with a telescopic rod, and the lower end of the telescopic rod is hinged to the upper end of the fixed frame.

[0012] The shoulder strap is fitted with a flexible sleeve at the shoulder strap position.

[0013] The beneficial effects of this utility model are as follows: A fixed frame is hinged to the lower end of the shoulder-mounted frame. The winding wheel is mounted on the fixed frame via a first rotating shaft. A winding rod is provided on one side of the winding wheel, and a driven gear is provided on the other side. The fixed frame is mounted with a driving gear that meshes with the driven gear via a second rotating shaft. A drive rod that can be connected to a handheld motor or hand crank is mounted on the second rotating shaft. The dual-drive mode is adapted to multiple scenarios. A telescopic rod is installed at the lower end of the shoulder-mounted frame, which can accommodate firefighters of different body types. When a firefighter carries the shoulder-mounted frame, the fixed frame will swing slightly, thus fitting more closely to the firefighter's back, optimizing the center of gravity, and reducing the extra force required for the body to balance the load. This effectively solves the problems of poor portability, single drive, and laborious operation of traditional winding devices. It is suitable for firefighting operations in complex terrains such as mountain roads and has high practicality and promotional value. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0019] Reference Figure 1-3 A dual-mode (hand-cranked and electric) shoulder-mounted hose reel includes a reel 1 and a shoulder-mounted frame 2. A fixed frame 3 is hinged to the lower end of the shoulder-mounted frame 2. The reel 1 is mounted on the fixed frame 3 via a first rotating shaft. A reeling rod 4 is mounted on one side of the reel 1, and a driven gear 5 that rotates synchronously with the reel 1 is mounted on the other side. A driving gear 6 that meshes with the driven gear 5 is mounted on the fixed frame 3 via a second rotating shaft. A drive rod 7 for connecting to a hand-held motor or hand crank is mounted on the second rotating shaft. When there is power support in the field or when long hoses need to be quickly reeled in, electric drive saves manpower and improves efficiency. In situations without power supply or with limited space, switching to hand-cranked drive allows for normal operation, effectively solving the problem of the single drive mode in traditional hose reels and adapting to different rescue environment needs.

[0020] The mounting frame 3 is equipped with a mounting bracket 17. The winding reel 1, driven gear 5, driving gear 6, first rotating shaft, second rotating shaft, etc. are all mounted on the mounting bracket 17. The mounting bracket 17 is equipped with a first bearing 9 via a first fixed seat 8. The first fixed seat 8 is fixedly connected to the outer ring of the first bearing 9. The first rotating shaft passes through the inner ring of the first bearing 9. The mounting bracket 17 is equipped with a second bearing 11 and a second rotating shaft via a second fixed seat 10. The second fixed seat 10 is fixedly connected to the outer ring of the second bearing 11. The second rotating shaft passes through the inner ring of the second bearing 11.

[0021] The bearing design significantly reduces frictional resistance during shaft rotation, minimizes component wear, extends equipment lifespan, and ensures the stability of the winding wheel and gear transmission during winding, preventing jamming.

[0022] The drive rod 7 has a center insertion hole 12, which is a square hole that allows for quick and easy connection to the output shaft of a handheld motor or a hand crank. This makes the operation simple and quick, without the need for complicated disassembly and assembly steps, thus improving the ease of use of the equipment. It is also compatible with various specifications of handheld motors and hand cranks on the market.

[0023] The lower end of the shoulder rack 2 is provided with a first limiting part 13 and a second limiting part 14 on both sides at the hinge position. The first limiting part 13 and the second limiting part 14 are used to limit the swing amplitude of the shoulder rack 2 and the fixed frame 3, so that it can be in an upright position when placed (as shown in the attached figure). Figure 1 , 2 As shown in the figure, it allows for faster and more direct carrying, while the swing range is 0°-20°, avoiding excessive swing, which would cause firefighters to consume extra energy when running due to excessive swaying.

[0024] The diameter of the driving gear 6 is smaller than that of the driven gear 5, forming a speed reduction transmission structure. When manually driven, the operating torque can be reduced by optimizing the gear ratio, making it easier for firefighters to manually crank and reel in the hose. At the same time, the stability of the gear meshing transmission ensures efficient power transmission and avoids power loss.

[0025] The lower end of the shoulder rack 2 is equipped with a telescopic rod 15, the lower end of which is hinged to the upper end of the fixed frame 3, so that it has a length adjustment function and can be adapted to firefighters of different body types.

[0026] The shoulder rack 2 is equipped with a flexible sleeve 16 at the shoulder position to cushion the back pressure.
