Description

Vulcanized joint structure with stretching detection function Technical Field The utility model mainly relates to the technical field of vulcanized joints, in particular to a vulcanized joint structure with a stretching detection function. Background The belt conveyor is widely applied to industries such as mines, ports, electric power and the like and is used for conveying bulk materials for a long distance. Because of the long conveying distance, the length of a single belt is limited, and multiple belt sections are usually connected into an ultra-long conveying belt through a vulcanized joint. The vulcanized joint adopts a hot vulcanization process to bond the rubber layer at the end of the belt with a reinforcing layer (such as a steel wire rope or fabric) to form a high-strength connection. However, in the actual operation process, the vulcanized joint is still a weak link of the whole conveyor belt, and the main reasons include long-term dynamic load influence, namely that the belt conveyor bears alternating tensile, bending and impact loads in operation, the vulcanized joint is easy to gradually deteriorate due to fatigue, the vulcanization process has the defects that if vulcanization temperature, pressure or time are not properly controlled, the joint adhesive strength is insufficient, local delamination or fracture is easy to occur, and a real-time monitoring means is lacking, namely that at present, manual regular inspection is mainly relied on, early damage of the joint is difficult to discover in time, and once the joint breaks, the whole belt is possibly invalid, so that serious shutdown accidents and economic losses are caused. In the prior art, visual inspection is adopted at the joint of the conveyer belt, the joint tensile state cannot be quantified by relying on experience, ultrasonic detection equipment is complex, shutdown detection is required, on-line monitoring is not suitable, a vibration sensor is adopted for monitoring, the belt running state can be indirectly reflected, and the joint tensile deformation cannot be accurately measured.
