When the conveyor belt passes through the conveyor belt non-destructive testing equipment through the conveying device, the radiation source emits X-rays, which penetrate the conveyor belt and are collected by the receiving plate in the receiving box located above the conveyor belt. In the process of penetrating the conveyor belt, the image of the inside of the conveyor belt is displayed, and finally it is judged whether the inside of the conveyor belt is damaged by analyzing the image.

[0004] During use of the above-mentioned detection equipment, since the radiation source is placed horizontally, the X-rays emitted by the radiation source can only be emitted in a direction perpendicular to the conveyor belt, and it is difficult to adjust the angle of the X-rays. It has poor flexibility and is difficult to cope with conveyors of different structural forms, and has a small scope of application. Summary of the invention

[0014] Through the above technical solution, the ray source starts to emit X-rays, which pass through the focusing bucket and then penetrate the conveyor belt to detect the conveyor belt. The focusing bucket diffuses the X-rays while reducing the possibility of X-rays leaking out of the bracket, thereby improving the safety of the operation of the conveyor belt non-destructive testing equipment.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiment of the present application discloses a conveyor belt nondestructive testing device.

[0031] Reference Figure 1 and Figure 2 The conveyor belt nondestructive testing equipment includes a bracket 1. In the embodiment of the present application, the bracket 1 is made of profile square tube welding. The profile square tube welding process has the advantages of high strength, convenient processing, economical and efficient. A mounting plate 2 is hinged on the bracket 1. A ray source for emitting X-rays is arranged on the mounting plate 2. A receiving box matching the ray source is arranged on the bracket 1. An adjustment component for adjusting the angle of the mounting plate 2 is arranged on the bracket 1. The adjustment component includes a frame 3 slidably connected to the bracket 1. The mounting plate 2 is hinged on the frame 3. Two movable bolts 4 are passed through the mounting plate 2. One end of the two movable bolts 4 is respectively hinged on the frame 3. The two movable bolts 4 are both passed through and threadedly connected with mounting nuts 5 and anti-loosening nuts 6 matching the movable bolts 4. The mounting nuts 5 are located between the mounting plate 2 and the frame 3. The mounting plate 2 is pressed tightly between the anti-loosening nuts 6 and the mounting nuts 5.

[0032] Therefore, when the angle of the radiation source needs to be adjusted, the operator rotates the mounting plate 2 to a suitable position according to the actual situation, and then rotates the mounting nut 5 to make the mounting nut 5 contact the mounting plate 2 to fix the angle of the mounting plate 2, thereby adjusting the angle of the X-ray emitted by the radiation source. This is highly flexible and convenient for coping with conveyors of different structural forms and models, thereby increasing the scope of application of conveyor belt nondestructive testing equipment. Rotating the anti-loosening nut 6 makes the mounting plate 2 press against the anti-loosening nut 6 and the mounting nut 5, thereby reducing the possibility of shaking of the mounting plate 2 and increasing the stability of the mounting plate 2.

[0033] Reference Figure 1 and Figure 2 The frame 3 is provided with a roller 7, and the bracket 1 is provided with a guide rail 8 matching the size of the roller 7, and the roller 7 is mounted on the guide rail 8. The roller 7 is moved along the guide rail 8 to change the position of the mounting plate 2. The roller 7 can be used to pull the radiation source out of the bottom of the bracket 1 during maintenance, so that the operator can easily move the position of the mounting plate 2, saving time and effort.

[0034] Reference Figure 1 and Figure 2 A protective shell 17 is bolted to the surface of the mounting plate 2 facing the detection channel 14. In the embodiment of the present application, the size of the threaded hole for mounting the protective shell 17 is slightly larger than the size of the bolt for mounting the protective shell 17. The radiation source is arranged inside the protective shell 17. The protective shell 17 is provided with a radiation port that matches the radiation source, and the X-rays of the radiation source pass through the radiation port. Four limit seats 18 are bolted to the mounting plate 2. The four limit seats 18 are respectively provided with limit bolts 19 and are threadedly connected. The four limit bolts 19 are arranged on both sides of the protective shell 17 in pairs, and the ends of the four limit bolts 19 facing the radiation source are in contact with the protective shell 17.

[0035] Therefore, the operator sets up the protective shell 17 on the mounting plate 2, and respectively installs the four bolts for installing the protective shell 17 into the corresponding threaded holes of the protective shell 17. At this time, the protective shell 17 is not completely fixed, and a certain amount of adjustment is reserved; the operator rotates the limit bolt 19, and the limit bolt 19 presses against the protective shell 17 toward the end of the protective shell 17 to generate a thrust on the protective shell 17, pushing the protective shell 17 to move, thereby fine-tuning the X-ray angle of the radiation source in the protective shell 17, and tightening the bolts for installing the protective shell 17 after adjusting it to a suitable position according to the actual use on site to completely fix the protective shell 17. The two limit bolts 19 on the opposite side press against the protective shell 17, thereby enhancing the stability of the placement of the protective shell 17.

[0036] Reference Figure 1, a convergence bucket 9 is arranged on the bracket 1, the open end of the convergence bucket 9 is arranged in the direction of the receiving box, the narrow end of the convergence bucket 9 corresponds to the radiation source, and the middle area of ​​the convergence bucket 9 constitutes a radiation channel. The convergence bucket 9 includes an upper horn bucket 10 arranged on the bracket 1, the open end of the upper horn bucket 10 is arranged in the direction of the receiving box, and the convergence bucket 9 also includes a lower horn bucket 11 bolted to the bracket 1, the open end of the lower horn bucket 11 corresponds to the narrow end of the upper horn bucket 10, the narrow end of the lower horn bucket 11 corresponds to the radiation source, and the middle area of ​​the upper horn bucket 10 and the lower horn bucket 11 constitutes a radiation channel. In the embodiment of the present application, the upper horn bucket 10 and the lower horn bucket 11 are made of lead plates, and the interiors of the upper horn bucket 10 and the lower horn bucket 11 can be provided with sealing sheet metal and a support frame for improving strength according to actual use conditions, and the shape of the lower horn bucket 11 can be customized according to the angle adjusted by the mounting plate 2.

[0037] Therefore, the ray source starts to emit X-rays, and the X-rays pass through the focusing bucket 9 and then penetrate the conveyor belt to detect the conveyor belt. The focusing bucket 9 diffuses the X-rays and reduces the possibility of X-rays leaking out of the bracket 1, thus playing a protective role and improving the safety of the conveyor belt nondestructive testing equipment. The operator can remove the lower horn bucket 11 from the upper horn bucket 10 by bolt disassembly, so as to realize the detachability of the lower horn and provide greater flexibility.

[0038] Reference Figure 1 The upper horn bucket 10 is fixedly connected with a mounting ring 12, and a mounting bolt 13 is passed through the mounting ring 12. The mounting bolt 13 passes through the bracket 1, and a connecting nut matching the size of the mounting bolt 13 is passed through and threadedly connected to the mounting bolt 13, and the bracket 1 is tightly pressed between the mounting bolt 13 and the connecting nut. The operator can remove the mounting bolt 13 from the bracket 1 by means of bolt disassembly, thereby realizing the detachability of the upper horn bucket 10, which is more flexible and convenient for the operator to replace different models of upper horn buckets 10.

[0039] Reference Figure 1 An annular sealing plate 15 matching the size of the upper horn bucket 10 is provided at one end of the upper horn bucket 10 facing the detection channel 14, the ray channel is located at the inner edge of the annular sealing plate 15, and a carbon fiber plate 16 matching the size of the annular sealing plate 15 is bonded to the inner edge of the annular sealing plate 15. In the embodiment of the present application, the size of the carbon fiber plate 16 covers the ray channel, and the X-rays from the radiation source can penetrate the carbon fiber plate to reach the receiving box. The carbon fiber plate 16 reduces the possibility of foreign matter entering the interior of the upper horn bucket 10 through the open end of the upper horn bucket 10 and affecting the detection effect. At the same time, the carbon fiber plate 16 has little effect on the shielding of the X-ray intensity, thereby improving the accuracy of the detection results of the conveyor belt non-destructive testing equipment.

[0040] The implementation principle of the embodiment of the present application is as follows: when the angle of the radiation source needs to be adjusted, the operator rotates the mounting plate 2 to a suitable position according to the actual situation, rotates the mounting nut 5 to make the mounting nut 5 contact the mounting plate 2, and rotates the anti-loosening nut 6 to make the mounting plate 2 press against the anti-loosening nut 6 and the mounting nut 5, so as to fix the angle of the adjusted mounting plate 2. The adjustment of the angle of the X-ray emitted by the radiation source is highly flexible and convenient for coping with conveyors of different structural forms and models, thereby improving the scope of application of the conveyor belt non-destructive testing equipment. While the focusing bucket 9 diffuses the X-rays, it reduces the possibility of X-rays leaking out of the bracket 1, plays a protective role, and improves the safety of the operation of the conveyor belt non-destructive testing equipment.
