AI Technical Summary
In the prior art, it is difficult to keep the dragging direction of the fire hose consistent with the rotation plane of the reel during the rewinding process. As a result, the fire hose is prone to axial twisting on the reel during the rewinding process, which is a technical defect that affects the rewinding efficiency and shortens the hose's lifespan.
The system employs a universally adjustable guide mechanism, which combines a universal joint with a guide tube to achieve adaptive guidance and straightening of the fire hose, allowing it to wind onto the reel in a naturally flat state, eliminating the possibility of kinking.
No need to stop and adjust midway, significantly improving winding efficiency, avoiding internal stress damage to the hose caused by kinking, and extending the service life of the hose.

Abstract
Claims
1. A fire hose winding device comprising a support (1), a reel (2) rotatably arranged on the support (1), and a crank (3) for driving the reel (2) to rotate, characterized in that: Also includes: Anti-kink guide mechanism, which is fixed to the bracket (1) by a mounting arm (4) and located on the inlet side of the reel (2); The anti-kink guiding mechanism includes a universal joint (5) and a guide tube (6). The guide tube (6) is connected to the mounting arm (4) through the universal joint (5), so that the inlet end of the guide tube (6) can freely deflect according to the change of the dragging direction of the fire hose. The channel profile of the guide tube (6) is configured to comb and guide the fire hose entering it so that it is wound onto the reel (2) in a naturally flat state.
2. A fire hose winding apparatus according to claim 1, wherein: The inlet end of the guide tube (6) is a flared structure with a flared mouth, and its outlet end is a flat and narrow structure adapted to the width of the fire hose.
3. A fire hose winding device according to any one of claims 1-2, characterized in that: The universal joint (5) is a ball joint, with its ball seat (501) fixed on the mounting arm (4), its ball head (502) fixed to one end of a connecting rod (7), and the other end of the connecting rod (7) fixedly connected to the outer wall of the guide tube (6).
4. A fire hose winding apparatus according to claim 3, wherein: The universal joint (5) is also provided with a damping adjustment mechanism (8) for adjusting the resistance torque when the universal joint (5) rotates.
5. A fire hose reeling device according to claim 4, characterized in that: The damping adjustment mechanism (8) includes a friction block (801), a spring (802), a connecting block (803), a pre-tightened threaded rod (804), and a threaded tube (805). The friction block (801) and the connecting block (803) are slidably arranged on the inner side of the ball seat (501). The spring (802) is also arranged on the inner side of the ball seat (501). The two ends of the spring (802) are respectively connected to the friction block (801) and the connecting block (803) through bearings. A threaded tube (805) is provided above the ball seat (501). A pre-tightening threaded rod (804) is threadedly connected to the inner side of the threaded tube (805). One end of the pre-tightening threaded rod (804) is connected to the top of the connecting block (803). The damping adjustment mechanism (8) tightens or loosens the pre-tightening threaded rod (804) to press or relax the spring (802) and adjust the friction force between the friction block (801) and the ball head (502).
6. A fire hose winding apparatus as defined in claim 1, wherein: The inner wall of the guide tube (6) is inlaid with a liner made of low-friction and wear-resistant material.
7. A fire hose winding apparatus as claimed in claim 6, wherein: The low-friction, wear-resistant material is ultra-high molecular weight polyethylene or nylon.
