[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please see Figures 1-3 In this embodiment of the present invention, a double-sided anti-corrosion layer detection device includes an equipment bracket 1, an equipment control box 2 is installed on one side of the equipment bracket 1, a rotating component for controlling the rolling of the pipeline to be detected is rotatably installed inside the equipment bracket 1, an external moving component and an internal moving component are respectively installed on the equipment bracket 1, an internal detection component for moving inside the pipeline is installed on the internal moving component, an external detection component for moving outside the pipeline is installed on the external moving component, and the external moving component and the internal moving component are connected to the same driving component.

[0024] When using the double-sided anti-corrosion coating inspection device, the pipe to be inspected is placed on the rotating component through the opening on one side of the equipment support 1. The pipe is fitted onto the inner moving component, and the outer moving component is located on the outer ring of the pipe. Activating the drive component can drive the outer and inner moving components to operate. The outer and inner moving components drive the outer and inner inspection components respectively to scan and inspect both sides of the pipe. When the inspection device is running, the rotating component can be activated, which can drive the pipe placed on top of it to roll, which can facilitate the comprehensive inspection of the pipe by the inspection device.

[0025] Furthermore, two sets of symmetrical positioning components are installed at the end of the internal moving component away from the drive component. Positioning blocks 3 corresponding to the two sets of positioning components are installed on one side of the equipment bracket 1. When the device is idle or the pipeline is installed, the positioning components are snapped onto the positioning blocks 3, which can provide stable auxiliary support for the internal moving component and prevent the device from deforming after long-term use.

[0026] In one embodiment, the internal moving component includes an internal drive screw 4 rotatably connected to the device bracket 1 at one end. One end of the internal drive screw 4 is connected to the drive component. Two sets of first auxiliary rods 5 are welded inside the device bracket 1, located on both sides of the internal drive screw 4. Support blocks 6 are welded to the ends of the two sets of first auxiliary rods 5 and rotatably connected to the other end of the internal drive screw 4. The support blocks 6 are connected to the positioning component. The internal detection component includes a movable block 7 threadedly connected to the internal drive screw 4. Internal detection probes 8 are installed at the top and bottom of the movable block 7. The movable block 7 is slidably connected to both sets of first auxiliary rods 5.

[0027] The rotation of the internal drive screw 4 can drive the movable block 7 to slide on the first auxiliary rod 5. The movable block 7 drives the upper and lower sets of internal detection probes 8 to move inside the pipe, enabling uniform detection of the anti-corrosion layer inside the pipe. Support blocks 6 are welded to the ends of the two sets of first auxiliary rods 5, which can improve the support strength of the internal moving components.

[0028] Specifically, the external moving component is rotatably installed inside the equipment bracket 1 with an external drive screw 9. A second auxiliary rod 10 is welded on the equipment bracket 1. One end of the external drive screw 9 is connected to the drive component. The external detection component includes a movable bridge 11 with one end threadedly connected to the external drive screw 9. The other end of the movable bridge 11 is slidably connected to the second auxiliary rod 10. Two sets of external detection ends 12 are symmetrically installed on the inner side of the movable bridge 11.

[0029] The rotation of the external drive screw 9 can drive the movable bridge 11 to slide on the second auxiliary rod 10. The movable bridge 11 drives the two sets of external detection heads 12 to move outside the pipeline, enabling uniform detection of the pipeline's external anti-corrosion layer.

[0030] Correspondingly, the drive assembly includes two sets of first drive wheels 13 fixedly installed at the end of the outer drive screw 9, a second drive wheel 14 fixedly installed at the end of the inner drive screw 4 and connected to one of the first drive wheels 13 via belt drive, a first motor 15 fixedly installed on the equipment bracket 1, and a third drive wheel 16 fixedly installed on the output shaft of the first motor 15 and connected to the other set of first drive wheels 13 via belt drive.

[0031] Start the first motor 15, which can drive the third transmission wheel 16 to rotate. The third transmission wheel 16 drives the first transmission wheel 13 to rotate via a belt. The first transmission wheel 13 drives the second transmission wheel 14 to rotate via a belt. This can easily realize the synchronous rotation of the external drive screw 9 and the internal drive screw 4, thereby enabling the external detection component and the internal detection component to move synchronously.

[0032] Based on the above embodiments, specifically, the positioning component includes a support column 17 welded to the support block 6, a connecting frame 18 rotatably connected to the support column 17, and a pin 19 slidably installed inside the end of the connecting frame 18 away from the support column 17. The pin 19 is used to insert into the interior of the positioning block 3 from top to bottom. When the pipe is installed on the equipment bracket 1, the two sets of positioning components are opened, and the pipe can pass through the positioning components and be placed on the rotating part. After the pipe is installed or the device is used, the connecting frame 18 is rotated. The connecting frame 18 rotates with the support column 17 as the support point. The pin 19 at the end of the connecting frame 18 is installed into the interior of the corresponding positioning block 3, which can provide stable support for the support block 6.

[0033] In one embodiment, the rotating component includes two sets of drive rollers 20 rotatably mounted inside the equipment bracket 1. One end of one set of drive rollers 20 is equipped with a single-layer driven wheel 21, and one end of the other set of drive rollers 20 is equipped with a double-layer driven wheel 22. The single-layer driven wheel 21 and the double-layer driven wheel 22 are connected by belt drive. A second motor 23 is fixedly mounted on the equipment bracket 1. The output shaft of the second motor 23 is fixedly connected to a drive wheel 24. The drive wheel 24 and the double-layer driven wheel 22 are connected by belt drive.

[0034] The second motor 23 is started, which drives the drive wheel 24 to rotate. The drive wheel 24 drives the single-layer driven wheel 21 and the double-layer driven wheel 22 to rotate. The synchronously rotating single-layer driven wheel 21 and double-layer driven wheel 22 can drive the two sets of drive rollers 20 to rotate in the same direction. The drive rollers 20 can drive the pipe placed on the top to roll.

[0035] The circuit connections between the components and the detection-related components are all existing technologies, and will not be elaborated on here. The transmission structure can also be replaced by sprockets and chains, and the appropriate structure should be selected according to the actual needs during production and application.
