[0002] A fire hose (fire water pipe) is a hose used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber lining and are wrapped with linen fabric on the outer surface. Advanced fire hoses are made of polymeric materials such as polyurethane. Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid injection pressure. Fire hoses are divided into two categories: lined fire hoses and leaky fire hoses. During use, the woven layer rubs against the ground and is prone to wear. Under the action of water pressure, the inner layer is prone to burst from the worn area, affecting the use. Therefore, it is necessary to detect the wear resistance of the product before leaving the factory;

A bidirectional telescopic rod 3 is fixedly installed on the top of the detection platform 1. Guide frames 4 are fixedly installed on both sides of the bidirectional telescopic rod 3 on the top of the detection platform 1. Moving plates 5 are symmetrically and movably installed at both ends of the top of the guide frame 4. Both ends of the bidirectional telescopic rod 3 are respectively connected to the bottoms of the two moving plates 5. Both sides of the moving plate 5 are respectively movably clamped in the middle of the guide frame 4. Installation frames 6 are fixedly installed on the tops of the two moving plates 5. One end of the installation frame 6 is rotatably installed with a rotating shaft 7. A grinding cylinder 8 is fixedly installed in the middle of the rotating shaft 7. A driving motor 9 is fixedly installed on the top of the installation frame 6. The output shaft of the driving motor 9 is connected to the top end of the rotating shaft 7. The bottom ends of the grinding cylinders 8, the top end of the rotating disk 11 and the top end of the winding disk 14 are all at the same horizontal height. By using the driving motor 9 to drive the rotating shaft 7 and the grinding cylinder 8 to rotate, the two grinding cylinders 8 are respectively located on both sides of the fire hose to perform grinding detection on the fire hose, and the wear resistance and quality of the fire hose can be directly detected. The detection method is simple. Moreover, the bidirectional telescopic rod 3 can pull the moving plate 5 to move along the guide frame 4 to adjust the positions of the two grinding cylinders 8, and ensure that the two grinding cylinders 8 can be closely attached to the surface of the fire hose during grinding, improving the accuracy of detection;

[0025] A positioning shaft 10 is fixedly installed at one end of the top of the detection platform 1. A rotating disk 11 is rotatably installed on the top of the positioning shaft 10. A winding motor 12 is fixedly installed at the end of the top of the detection platform 1 away from the positioning shaft 10. A support frame 13 is fixedly installed at the corresponding position of the top end of the detection platform 1 and the winding motor 12. A winding disk 14 is rotatably installed on the top of the support frame 13. Limit posts 15 are symmetrically and fixedly installed at both ends of the top of the detection platform 1. The output shaft of the winding motor 12 is connected to the bottom end of the winding disk 14. The two limit posts 15 are respectively located on one side of the rotating disk 11 and the winding disk 14. By the combined use of the winding motor 12 and the winding disk 14, the fire hose is tractioned and pulled so that it passes through the grinding detection. The traction method is simple, and the fire hose placed on the rotating disk 11 can be directly wound up after detection, restored from the rolled state to the wound and coiled state. At the same time, the limit posts 15 keep the fire hose in a limited and taut state;

[0026] In the middle of the top of the detection platform 1, a fixing frame 16 is symmetrically and fixedly installed. In the middle of the fixing frame 16, a swinging frame 17 is rotatably installed. In the middle of the swinging frame 17, a magnifying mirror surface 18 is embedded. At both ends of the swinging frame 17, rotating rods 19 are symmetrically and fixedly connected. A locking knob 20 is sleeved on the surface of the rotating rod 19. The rotating rod 19 movably penetrates through the fixing frame 16. The locking knob 20 is threadedly connected with the rotating rod 19. The locking knob 20 is closely attached to the surface of the fixing frame 16. Through the combined use of the swinging frame 17 and the magnifying mirror surface 18, the fire hose after grinding and detection is magnified and irradiated, which is convenient for the staff to observe on one side, improves the convenience of observation, and the observation result after magnification can more easily see the subtle changes. At the same time, through the combined use of the rotating rod 19 and the locking knob 20, the inclination angle of the swinging frame 17 and the magnifying mirror surface 18 can be adjusted, which is convenient for timely adjustment according to the observation line of sight of the staff.

[0027] The working principle and usage process of the present utility model are as follows: First, the staff takes the fire hose roll to be detected, places the hose on the surface of the rotating disc 11, holds the end of the hose tightly against the surface of the limiting column 15, and sequentially passes through the middle parts of the two grinding cylinders 8 and the middle parts of the two swinging frames 17, then closely attaches to the surface of another limiting column 15, and finally fixes it on the top of the winding disc 14. The two ends of the bidirectional telescopic rod 3 contract simultaneously, pulling the two moving plates 5 to move along the guiding frame 4, so that the two mounting frames 6 approach each other, and the positions of the two grinding cylinders 8 are adjusted until the two grinding cylinders 8 are respectively closely attached to both sides of the fire hose. And the staff can turn the locking knob 20 to loosen the fixation of the rotating rod 19, adjust the inclination angle of the swinging frame 17 and the magnifying mirror surface 18, so that the staff can conveniently observe the surface of the fire hose through the magnifying mirror surface 18, and then tighten the locking knob 20 to make the swinging frame 17 stop shaking;

[0028] The winding motor 12 is started to drive the winding disc 14 to rotate, which plays a role of winding and pulling the fixed fire hose, pulling the rotating disc 11 to rotate, and gradually loosening and moving forward the fire hose on its top. At the same time, the driving motor 9 is started to drive the rotating shaft 7 and the grinding cylinder 8 to rotate. The grinding cylinder 8 rotates closely attached to the fire hose, and will grind its surface, thereby detecting the wear degree of the fire hose under a certain strength during grinding. The fire hose is continuously pulled forward. When the grinding position passes through the magnifying mirror surface 18, the staff can observe the magnified pattern of the grinding position through the magnifying mirror surface 18, which is more convenient to observe the wear state during grinding. After the detection is completed, the fire hose is wound and wound on the top of the winding disc 14, and still remains in the winding state after passing the detection, and can be directly taken off and stored.
