Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of hydraulic pipeline reel, specifically relates to a foldable portable reel. BACKGROUND

[0002] In fire rescue and other scenes, hydraulic power source liquid supply rescue plays a vital role. The hydraulic power source drives the fire pump, hydraulic rescue tool and other equipment by generating high pressure and high flow power, providing strong support for rescue work. The winding of the fire hose must be wound from the middle of the hose, keeping the metal nozzle and metal connector on the outermost side of the hose reel, and then placed in the hose window, waiting for the next use, so the electric reel machine is needed to automatically wind the fire hose together, playing the role of storing the fire hose.

[0003] The existing reel machine on the market mainly improves the functionality and other aspects, which has the advantages of multi-functionality such as conveying high-pressure water for rapid fire extinguishing, but the reel machine is not convenient for quick winding and storage of the hose after the fire is extinguished, and it is also not convenient to move the reel machine to the fire scene.

[0004] After searching in the existing published documents, the utility model patent with patent publication number CN213568875U discloses a hose reel machine, which improves the winding effect through the improvement of the reel structure, and realizes the effect of convenient movement through the supporting frame and the electrically controlled universal wheel. However, in the emergency state of fire extinguishing scene and similar fire scene, the assembly of the motor increases the overall weight, and the lowering of the electric universal wheel prolongs the waiting time, so it is still impossible to realize the effect of quick transfer, storage and immediate use.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figs. 1 to 3 As shown, this embodiment provides a foldable portable reel, including a reel assembly 1.

[0028] The reel assembly 1 is movably mounted on the movable base 2, and a folding handrail 3 is also fixed on the movable base 2.

[0029] The reel assembly 1 comprises two circular reels 4, the centers of which are provided with a center shaft 5; four aluminum limiting rods 6 are welded equidistantly between the circular reels 4 and parallel to the center shaft 5. The double circular reels are rigidly connected by the center shaft 5 and the four aluminum limiting rods 6, which not only ensure the synchronization of the synchronous rotation of the reels, but also effectively prevent the reels from deviating or deforming through the parallel constraint of the aluminum lightweight characteristics and the limiting rods, thereby improving the load capacity.

[0030] The movable base 2 comprises two triangular side plates 7, one bottom angle of which is fixed by a connecting plate 8, and the bottom is provided with a rubber foot pad 9; the other bottom angle of the two triangular side plates 7 is movably provided with an axle 10, and the both ends of the axle 10 are fixed with casters 11. The triangular side plates 7 are provided at the bottom with the rubber foot pad 9 and the casters 11, which can realize flexible turning of 360° when moving and can be fixed by increasing the friction through the foot pad when stationary, thereby adapting to complex ground such as construction site and lawn and effectively preventing the device from sliding sideways during winding and unwinding.

[0031] The reel assembly 1 is movably installed on the triangular side plate 7 through the center shaft 5; the handle assembly 12 is fixed to the top of one end of the center shaft 5, and the both ends of the handle assembly 12 are respectively provided with a rotating handle 13 and an extension pin 14, as shown in Fig. 2 The extension pin 14 is a spring-loaded knob plunger. The triangular side plate 7 and the handle assembly 12 are further provided with a positioning disc 15, which is fixed on the triangular side plate 7 and is provided with a plurality of positioning grooves 16 at the outer edge. When the reel assembly 1 needs to be manually wound and unwound, the extension pin 14 is pulled out and rotated by 90°, as shown in Fig. 3 The extension pin 14 is kept in the state of retraction, and when the winding and unwinding is completed or the device is in a moving or storing state, the extension pin 14 is again pulled out and rotated by 90° and released, and the front end will return to the protruding state and be clamped into the positioning groove 16, thereby realizing the fixation of the reel assembly 1.

[0032] The folding handrail frame 3 is divided into a handrail 17 and a trolley chassis 18, the trolley chassis 18 is installed on one side of the triangular side plate 7 close to the caster 11, and the handrail 17 and the trolley chassis 18 are connected through a backfolding device 19. The backfolding device 19 is an auxiliary component commonly used for folding on a wheelchair, and is characterized in that the handrail 17 can be quickly folded and stored and reset through the pressing piece on the surface of the backfolding device 19, is very suitable for fire rescue scenes requiring quick positioning, can be matched with the equipment profile to reduce the volume during transportation, and can provide a support height conforming to ergonomics for an operator during operation; the top handle design meets the requirements of special scenes such as stair carrying, and forms a multi-dimensional movement mode of "lifting-pushing-pulling".

[0033] The top end of the two triangular side plates 7 is also provided with a handle 20. When the whole device is in a folded state, the two handles 20 can be used to quickly carry the device to the required position, improving the storage efficiency.
