Description

Technical Field

[0001] The invention relates to the technical field of belt longitudinal tear prevention detection technology, and in particular to a belt longitudinal tear prevention detection device based on ultrasonic technology. Background Art

[0002] A belt conveyor is a mechanical device that is driven by friction to transport materials in a continuous manner. It can transport both loose materials and piece items. After a long period of transporting loose materials or piece items with sharp surfaces, its surface is scratched and affected by the gravity of the objects, causing longitudinal tears on the belt surface. If not discovered in time, the material will fall along the tears during the conveying process, affecting its conveying efficiency and increasing the subsequent cleaning and collection process.

[0003] Traditional belt anti-longitudinal tear detection uses a weight sensor to detect whether the upper end of the belt conveying materials is dropping material downward. When the belt is leaking, it can only detect the belt with a larger degree of tearing, and cannot promptly know whether the belt surface has a smaller degree of tearing. At this time, it is no longer possible to take preventive and remedial measures, and the cleaning and collection processes will still be added later. In addition, when the traditional detection method is used to detect the belt conveying materials, if the material particles at that part of the belt are larger than the tear size, no material will fall. Therefore, it is impossible to accurately detect whether the belt is torn. Summary of the invention

[0039] See also Figure 4 and Figure 8The detection component 26 includes an ultrasonic probe 261, and the middle part of the U-shaped plate 241 is slidably connected to the ultrasonic probe 261, and the ultrasonic probes 261 are fixedly connected by a horizontal plate 262. A distance control cylinder 263 is fixedly installed on the upper end of the leftmost guide column 231, and the telescopic end of the distance control cylinder 263 is fixedly connected to the leftmost ultrasonic probe 261.

[0040] The working principle of the present invention is as follows: when the belt on the belt conveyor moves downward, the motor 12 drives the cleaning column brush 134 to rotate clockwise to clean the impurities attached to the lower end surface of the belt. Under the cooperation of the gear 131, the gear 2 132 and the gear 3 133, the dust wiping column 135 rotates clockwise to wipe the cleaned belt surface to ensure that the belt surface is clean. The clockwise rotating cleaning column brush 134 and the dust wiping column 135 are opposite to the movement direction of the belt to prevent a small amount of dust from moving to the belt surface on the left side of the cleaning column brush 134 and the dust wiping column 135 due to inertia during the cleaning and wiping process. The cleaning column brush 134 and the dust wiping column 135 contact the material moving rod 143 during the rotation process, so that the impurities and dust attached to the surface of the cleaning column brush 134 and the dust wiping column 135 are moved to the collection box 141 for collection, and the clean surface of the belt continues to move to the left.

[0041] The coupling agent in the containing box is pumped to the shunt pipe 243 through the delivery pump 245 through the main control pipe 244, and finally enters the discharge pipe 242 on the U-shaped plate 241 and is discharged upward, and flows along the guide groove 255 and the inclined groove 254 to the surface of the ultrasonic probe 261 until it fills the space formed between the ultrasonic probe 261 and the inclined groove 254 and the guide groove 255. At this time, the motor 233 drives the threaded rod 234 to rotate forward, thereby driving the moving block 235 to move backward under the limiting guidance of the positioning round rod 236, and then drives the guide column 231 adjacent to the moving block 235 to move backward. With the cooperation of the connecting rod 232, all the guide columns 231 move backward together, driving the U-shaped plate 241 to move backward. At this time, the leftmost ultrasonic probe 261 is driven to move upward by the distance control cylinder 263 until the upper surface of the leftmost ultrasonic probe 261 is flush with the highest point of the corresponding U-shaped plate 241. Driven by the horizontal plate 262, the The upper surfaces of some ultrasonic probes 261 are flush with the highest point of the corresponding U-shaped plate 241. At this time, the upper surface of the ultrasonic probe 261 is in close contact with the lower end surface of the belt, and ultrasonic detection is performed on the lower surface of the belt. When the ultrasonic probe 261 moves to the last end of the belt, the motor 233 drives the threaded rod 234 to rotate in the opposite direction, and the detection is continued until the ultrasonic probe 261 and the U-shaped plate 241 return to the initial position. During the whole process, the discharge pipe 242 always discharges the coupling agent, part of the coupling agent enters between the belt and the ultrasonic probe 261 to exhaust the air, and part of the coupling agent overflows into the arc groove plate 251, and enters the discharge pipe 242 along with the feeding pipe 252 for recycling. The one-way valve 253 prevents the coupling agent flowing to the discharge pipe 242 from entering the feeding pipe 252 again with the negative pressure. With the movement of the belt and the movement of the ultrasonic probe 261, the ultrasonic probe 261 moves on the trigonometric function image on the belt, and detection is performed during the movement.

[0042] During the detection process, the belt moves to the left all the time, and the external motor drives the cleaning agent column 16 to rotate clockwise, thereby wiping the coupling agent on the belt surface, and the coupling agent on the surface of the cleaning agent column 16 is scraped off by the scraper plate 172 at the upper end of the scraper column 171. After a period of time, when the cleaning agent column 182 is located at the front end of the belt, the positioning column 1734 is taken out, and the control handle 173 is rotated to exchange the positions of the scraper columns 171 on the upper and lower sides, and then the positioning column 1734 is inserted into the cylindrical hole 1731 and the cylindrical hole 2 1733. At this time, the scraper column 171 located above scrapes off the coupling agent on the surface of the cleaning agent column 16, and the cleaning agent column 182 is driven by the linkage rod 184 and guided by the fixed column 181, and moves backward together with the guide column 231 to scrape off the coupling agent on the scraper column 171 below, so as to avoid excessive coupling agent adhering to the surface of the scraper column 171, thereby affecting the scraping effect of the scraper column 171.
