[0031] Reference Figure 1-4 , a chemical pipeline outer wall detection device, is used for outer wall defect detection of pipelines, in order to improve the efficiency and accuracy of pipeline outer wall detection.

[0032] The chemical pipeline outer wall detection device includes a base 1, multiple support components and a detection component;

[0033] The supporting components are arranged at intervals on the base 1. Each supporting component includes a driving wheel 203 and an auxiliary wheel 702. The outer walls of the driving wheel 203 and the auxiliary wheel 702 are provided with rubber sleeves to facilitate the driving wheel 203 and the auxiliary wheel 702 to support the pipeline 4.

[0034] A plurality of first support rods 201 are fixedly connected to the base 1, and each driving wheel 203 is arranged at the top of a first support rod 201. A servo driving motor 202 is provided at the top of each first support rod 201, and the output shaft of the servo driving motor 202 is connected to the driving wheel 203, thereby driving the driving wheel 203 to rotate.

[0035] A guide rail 6 is fixedly connected to the base 1, and a slide groove is provided at the bottom of the movable plate 5. The guide rail 6 is located inside the slide groove. A plurality of second support rods 701 are fixedly connected to the top of the movable plate 5. Each auxiliary wheel 702 is arranged at the top of a first support rod 201. The movable plate 5 can be moved along the guide rail 6 through the guide rail 6, so that the auxiliary wheel 702 is close to or away from the driving wheel 203, so that the auxiliary wheel 702 and the driving wheel 203 can support pipes 4 of different diameters, and a plurality of fixing holes are arranged at intervals on the guide rail 6. A through hole is opened on the movable plate 5, and a pin 501 is provided in the through hole. The bottom end of the pin 501 can be inserted into the fixing hole. The movable plate 5 can be fixed to the base 1 through the pin 501, thereby fixing the position of the auxiliary wheel 702.

[0036] The driving wheel 203 and the auxiliary wheel 702 are symmetrically arranged along the axial vertical plane of the pipeline 4, and the axes of the driving wheel 203 and the auxiliary wheel 702 have an inclined angle with the axis of the pipeline 4, so that the driving wheel 203 drives the pipeline 4 to perform a spiral feeding motion.

[0037] There are multiple detection components, and they are arranged at intervals on the base 1, so that multiple detections can be performed when the pipe 4 is spirally fed, thereby ensuring the accuracy of the detection data. The detection component includes a dial indicator 301 and a rotating rod 302. The rotating rod 302 is rotatably connected to the base 1. The dial indicator 301 is set at the top of the rotating rod 302, and can be used for detection of pipes 4 of different diameters. The rotating rod 302 is rotated so that the measuring needle of the dial indicator 301 contacts the outer wall of the pipe 4, and a fastening screw 303 is provided at the connection between the base 1 and the rotating rod 302 to fix the rotating rod 302, so that the position of the dial indicator 301 is fixed.

[0038] The working principle of the chemical pipeline outer wall inspection device is as follows: first, the distance between the driving wheel 203 and the auxiliary wheel 702 is adjusted according to the diameter of the pipeline 4 to be inspected, so that the pipeline 4 can be stably placed on the driving wheel 203 and the auxiliary wheel 702. During adjustment, the pin 501 is pulled out to move the movable plate 5 along the guide rail 6, thereby moving the auxiliary wheel 702 closer to or away from the driving wheel 203. After the adjustment is completed, the bottom end of the pin 501 is inserted into the fixing hole. The pin 501 can fix the movable plate 5 to the base 1, thereby fixing the position of the auxiliary wheel 702. At this time, the pipeline 4 to be inspected is placed on the driving wheel 203 and the auxiliary wheel 702.

[0039] Then, the rod 302 is rotated so that the measuring needle of the dial indicator 301 contacts the outer wall of the pipe 4, and then the fastening screw 303 is tightened to fix the rotating rod 302 so that the position of the dial indicator 301 is fixed;

[0040] Finally, the driving wheel 203 is driven to rotate by the servo drive motor 202. Since the radial plane of the driving wheel 203 has an inclination angle with the radial plane of the pipe 4, the pipe 4 will perform a spiral feed motion. Therefore, the measuring needle of the dial indicator 301 will perform a relative spiral motion on the outer wall of the pipe 4, and the outer wall of the pipe 4 will be fully inspected.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
