[0025] Depend on Figure 1-5 The present invention relates to a testing device for processing anti-corrosion steel pipes, including a base 1, a sliding frame 2 installed on the top of the base 1, and a steel pipe testing component 3 arranged above the sliding frame 2.
[0026] The steel pipe inspection component 3 includes two support frames 301 symmetrically arranged above the sliding frame 2. The top of the support frame 301 is provided with a semi-circular groove 302. Steel pipe support units 303 are arranged at equal angles on the inner side of the semi-circular groove 302. The top of the support frame 301 is provided with a rotation drive unit 304. The bottom of the support frame 301 is fixedly installed with a slider 4. The slider 4 is slidably connected to the sliding frame 2. A double-ended screw 5 is rotatably installed inside the sliding frame 2. The two sliders 4 are respectively threaded to two threaded grooves with opposite directions on the double-ended screw 5. One end of the double-ended screw 5 is fixedly connected to the output shaft of the stepper motor 6. The stepper motor 6 is fixedly installed on the sliding frame 2.
[0027] The steel pipe support unit 303 includes support rollers 3034 that are equally spaced inside the semi-circular groove 302. The support frame 301 has circumferential movable grooves 3031 that are equally spaced inside. The circumferential movable grooves 3031 correspond one-to-one with the support rollers 3034. A movable plate 3032 is movably installed inside the circumferential movable groove 3031. A mounting frame 3033 is installed on the side of the movable plate 3032 that is close to the semi-circular groove 302. The support rollers 3034 are installed on the mounting frame 3033. A return spring 3035 is symmetrically installed on the side of the movable plate 3032 that is away from the semi-circular groove 302. One end of the return spring 3035 is fixedly connected to the inner wall of the end of the circumferential movable groove 3031 that is away from the semi-circular groove 302.
[0028] The rotation drive unit 304 includes a top plate 3044 disposed above the support frame 301. The support frame 301 has symmetrically arranged side movable slots 3041 inside. A longitudinal moving plate 3042 is movably installed inside the side movable slots 3041. Support rods 3043 are symmetrically installed on the top of the longitudinal moving plate 3042, and the top of the support rods 3043 is fixedly connected to the top plate 3044. A steel pipe detection unit 305 is installed on the top of the top plate 3044. A rotating screw 3045 is rotatably installed inside one of the side movable slots 3041. The rotating screw 3045 is threadedly connected to the longitudinal moving plate 3042, and one end of the rotating screw 3045 is fixedly connected to the output shaft of a drive motor 3046. The drive motor 3046 is fixedly installed at the bottom of the support frame 301. A rotating frame 3047 is fixedly installed at the bottom of the top plate 3044. A rotating roller 3048 is rotatably installed on the rotating frame 3047. One end of the rotating roller 3048 is fixedly connected to the output shaft of the rotating motor 3049. The rotating motor 3049 is fixedly installed on the rotating frame 3047. Multiple support rollers 3034 are movably installed on the inner side of the semi-circular groove 302, so that the support rollers 3034 can support steel pipes of different diameters. At the same time, the top plate 3044 moves downward, so that the rotating roller 3048 contacts the top wall of the steel pipe, which facilitates the limiting of steel pipes of different diameters and facilitates inspection. Meanwhile, the two support frames 301 can move relative to each other, which facilitates the inspection of the steel pipe in the length direction. The rotation of the rotating roller 3048 drives the main rotation of the steel pipe, which facilitates the inspection of the steel pipe in the circumferential direction.
[0029] The steel pipe inspection unit 305 includes a rotating shaft 3051 rotatably mounted on a top plate 3044. A mounting platform 3052 is mounted on the top of the rotating shaft 3051, and a flaw detector 3053 is mounted on the top of the mounting platform 3052. Two flaw detectors 3053 are located on the side of two support frames 301 that are close to each other. A driven gear 3054 is mounted on the rotating shaft 3051, and a driving gear 3055 is meshed with one side of the driven gear 3054. The driving gear 3055 is fixedly connected to the output shaft of a servo motor 3056, which is fixedly mounted on the top plate 3044. On the top plate 3044, a flaw detector 3053 is mounted on a mounting platform 3052. The rotating shaft 3051 at the bottom of the mounting platform 3052 is rotatably connected to the top plate 3044. Two flaw detectors 3053 are located on two support frames 301 close to each other. When the support frame 301 moves to a position close to the middle of the steel pipe, one of the flaw detectors 3053 is rotated to the other side, making it convenient for one of the flaw detectors 3053 to inspect the steel pipe. When the two flaw detectors 3053 move to a position where the two support frames 301 are far apart, it is convenient to inspect both ends of the steel pipe.
[0030] Working principle: During operation, the steel pipe to be inspected is first placed in the semi-circular grooves 302 on the two support frames 301, so that each support roller 3034 supports the steel pipe. Since the movable plate 3032 at the bottom of the support roller 3034 is equipped with a return spring 3035, each support roller 3034 can contact the outer wall of steel pipes of different diameters. Then, the drive motor 3046 is turned on, so that the rotating screw 3045 rotates. Since the rotating screw 3045 is threadedly connected to the longitudinal plate 3042, it drives the top plate 3044 to move downward until the rotating roller 3048 contacts the top wall of the steel pipe, thereby limiting the steel pipe and facilitating the inspection of the steel pipe.
[0031] Then, the flaw detector 3053 is turned on to inspect the outer wall of the steel pipe below. The rotating motor 3049 is turned on, causing the rotating roller 3048 to rotate. Under the friction of the rotating roller 3048, the steel pipe rotates, which facilitates the flaw detector 3053 to inspect the circumferential direction of the steel pipe. When the stepper motor 6 is turned on, the double-ended screw 5 rotates. Since the two sliders 4 are threadedly connected to the threaded grooves with opposite directions on the double-ended screw 5, the two support frames 301 are moved relative to each other, so that the flaw detector 3053 moves along the length of the steel pipe to perform the inspection.
[0032] When the two support frames 301 approach the middle of the steel pipe, one of the servo motors 3056 is turned on. After the drive gear 3055 rotates, it drives the rotating shaft 3051 to rotate through the driven gear 3054, rotating the flaw detector 3053 to the other side of the support frame 301. This moves the flaw detector 3053 on the other support frame 301 to the position above the middle of the steel pipe, facilitating the inspection of the middle of the steel pipe. At the same time, when the two flaw detectors 3053 rotate with the rotating shaft 3051 to the side where the two support frames 301 are far apart, they can inspect the outer walls of both ends of the steel pipe, facilitating a comprehensive inspection of the steel pipe.
