Technical Field
[0001] The utility model relates to the technical field of conveying hose detection, in particular to a hose assembly convenient for detecting the wear limit. Background Art
[0002] A hose is a kind of tubular rubber product used to convey oil, slurry or granular materials. During the working process of the hose, especially when conveying dry cement, dry lime and other powder materials or wet materials such as concrete and cement slurry, the inner lining will inevitably be worn. The wear degree of the inner lining of the hose cannot be directly detected. The prior art generally uses an industrial endoscope for detection. During detection, the hose needs to be disassembled on site, and the process is cumbersome and the efficiency is low.
[0003] In order to solve the technical problem that the hose needs to be disassembled when detecting the wear degree of the inner lining of the hose, resulting in a reduction in detection efficiency, the utility model provides a hose assembly convenient for detecting the wear limit.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0025] As shown in the Figures 1 to 5 accompanying drawings, a hose assembly facilitating the detection of wear limits includes an inner liner 8, a sealing tube 9 covering the outside of the inner liner 8, a detection wire disposed between the inner liner 8 and the sealing tube 9, and a hose joint 1 fixedly provided at one end of the inner liner 8 and the sealing tube 9.
[0026] One end of the hose joint 1 is provided with an embedding groove 12, and a sealing ring 4 is fixed on the inner end face of the embedding groove 12. One ends of the inner liner 8 and the sealing tube 9 extend into the embedding groove 12 and abut against the sealing ring 4.
[0027] The detection wire includes a wire one 5 and a wire two 6. The wire one 5 and the wire two 6 are evenly wound around the inner liner 8. The inner ends of the wire one 5 and the wire two 6 are connected to each other, and the other ends are respectively fixedly connected to one ends of two leads 2. The other ends of the two leads 2 are separately connected to a multimeter.
[0028] A skeleton tube 10 is covered and disposed outside the sealing tube 9, and an outer covering tube 11 is covered and disposed outside the skeleton tube 10. The inner liner 8, the sealing tube 9, the skeleton tube 1, and the outer covering tube 11 together form a conveying hose 3, and the side part of the conveying hose 3 is fixedly connected to the inner side surface of the embedding groove 12.
[0029] A notch 7 is provided on the outer surface of the hose joint 1. A through hole 13 is provided between the notch 7 and the embedding groove 12. The through hole 13 is provided on the hose joint 1. One ends of the two leads 2 pass through the through hole 13 and are disposed in the notch 7. The notch 7 is an elliptical groove.
[0030] The inner liner 8, the sealing tube 9, the skeleton tube 10, and the outer covering tube 11 are all formed by winding and heat vulcanization treatment.
[0031] The specific working process of the present invention:
[0032] When a tester measures the wear degree of the inner liner 8, first remove the shielding object covering the notch 7, and then use the multimeter to measure the on-off situation of the wire one 5 and the wire two 6. Turn the multimeter to the buzzer gear, and then connect the two test leads of the multimeter to the wire one 5 and the wire two 6 respectively. If there is a numerical change in the multimeter and a buzzer alarm is issued, the wire one 5 and the wire two 6 are in a conducting path, otherwise they are in an open circuit.
[0033] The first wire 5 and the second wire 6 are laid outside the inner lining tube 8. After the inner lining tube 8 is worn through, the first wire 5 and the second wire 6 will be exposed, and the first wire 5 and the second wire 6 will be worn by the conveyed material. This state will last for a period of time until the first wire 5 and the second wire 6 are worn off. The length of the wear-off time is related to the conveyed material. Because of the existence of the sealing tube 9, the wear of the inner lining tube 8 will not cause the hose to leak.
[0034] Under normal conditions, the result measured by the multimeter is a conductive state. The conductive state indicates that the multimeter, the first wire 5 and the second wire 6 form a loop, proving that the first wire 5 and the second wire 6 are not worn or the wear is not serious. At this time, there is no need to replace the conveying hose 3; if the detection notch 7 is in an open state, the open state means that there is no loop formed between the multimeter, the first wire 5 and the second wire 6, that is, it indicates that there is a break in the first wire 5 or the second wire 6, which proves that the inner lining of the conveying hose 3 has been worn through and the detection wire has also been worn off. At this time, the conveying hose 3 needs to be replaced.
[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
