Description

Technical Field

[0001] This utility model relates to the field of ultrasonic pipeline testing technology, and in particular to an adjustable pipeline fixing device for ultrasonic testing. Background Technology

[0002] During pipeline production, ultrasonic testing devices are used to inspect the pipelines and determine their usability. This inspection requires supporting devices to secure the pipelines; however, conventional support devices have some drawbacks, such as:

[0003] Traditional pipe fixing devices cannot adjust the position or angle of the pipe during use, making it difficult to inspect various parts of the pipe. This limits the effectiveness of the pipe fixing device and hinders its use. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable pipe fixing device for ultrasonic flaw detection, so as to solve the problems mentioned in the background art.

[0005] An adjustable pipe fixing device for ultrasonic flaw detection includes a base plate and a fixing frame: the base plate has an extension support mechanism inside, a central column is provided at the upper end of the base plate, a height adjustment mechanism is provided inside the central column, a fixing frame is provided at the upper end of the height adjustment mechanism, a roller is provided inside the fixing frame, and limit mechanisms are provided on both sides of the fixing frame.

[0006] Preferably, the extension support mechanism includes a slide groove and an extension support plate. The slide groove is opened at an equal angle inside the base plate. The extension support plate, which is slidably arranged in a "Z" shape, is provided inside the slide groove. A limiting groove for the extension support plate is provided at the upper end of the slide groove.

[0007] When the device is not in use, the extension support plate is inserted into the slide groove to fold and store it. When the device is in normal use, the extension support plate is moved to the outermost position. As the bottom surface of the extension support plate and the bottom surface of the base plate simultaneously contact the ground, the extension support plate will rotate, causing the upper end of the extension support plate to be inserted into the limiting groove, thereby fixing the extension support plate and preventing it from moving inward. The slide groove also limits the extension support plate and prevents it from moving outward. Gravity is used to fix the extension support plate and the slide groove.

[0008] Preferably, the slide groove is provided with a locking block inside, and the corner of the extension support plate is provided with a corresponding locking groove.

[0009] When the extension support plate is stored, the slot engages with the locking block to fix the extension support plate in place, thereby allowing the extension support plate to support the device.

[0010] Preferably, the height adjustment mechanism includes a worm, a worm wheel, a lead screw, and a support column. The worm is rotatably disposed inside the central column, the worm wheel is disposed on the outer side of the worm, the worm wheel is rotatably disposed inside the central column, the lead screw is disposed at the upper end of the worm wheel, the support column is disposed on the outer side of the lead screw, the support column is slidably disposed inside the central column, and the lead screw is rotatably disposed inside the central column.

[0011] When the device is in use, the worm can be rotated to drive the worm wheel to rotate, but the worm wheel cannot drive the worm to rotate. Therefore, when the device is not adjusted, it can self-lock, and the lead screw will rotate with the worm wheel. When the lead screw rotates, since the lead screw and the support column are connected by a thread, and the central column will limit the support column, the support column can only move up and down, so the height of the support column will be adjusted, and thus the overall height of the device will be adjusted.

[0012] Preferably, a motor is provided on the side of the roller, and the motor is located inside the fixed frame.

[0013] The roller is driven by a motor to rotate. When the roller rotates, it drives the pipe on its surface to rotate, thereby adjusting the position of the pipe. At the same time, you can replace the roller to make the surface texture different, thereby changing the direction of the friction force on the pipe when the roller rotates. This allows you to adjust the pipe's position and angle at the same time, making it easier to perform ultrasonic flaw detection on different parts of the pipe.

[0014] Preferably, the limiting mechanism includes a limiting frame and a fixing bolt. The limiting frame is arc-shaped and is slidably disposed inside the fixing frame and fixed by the fixing bolt.

[0015] When the device is in use, the length of its extension can be adjusted by moving the limit bracket, and then the limit bracket can be fixed by using the fixing bolt.

[0016] Preferably, an electric push rod is provided at the end of the limiting frame away from the fixed frame, and the extended end of the electric push rod is rotatably connected to a support frame, and a roller is rotatably provided inside the support frame.

[0017] When the device is in use, the support frame and rollers can limit the movement of the pipeline. When the pipeline rotates, the support frame and rollers will also rotate under the action of friction, thus preventing the support frame and rollers from obstructing the rotation of the pipeline and making it easier to detect different positions of the pipeline.

[0018] The beneficial effects of this utility model are:

[0019] 1. When the device is in use, the position of the roller can be adjusted according to the width of the pipe, so as to facilitate the support of different pipes. Then, different rollers can be replaced to change the direction of the friction force provided, so that when it rotates, it can not only adjust the position of the pipe, but also the angle of the pipe, thus facilitating the detection of different positions of the pipe.

[0020] 2. When the device is in use, the extended support plate can be moved outward to increase the support area at the bottom of the device, thereby improving the stability of the bottom of the device during use. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In practical implementation: such as Figure 1-4As shown, an adjustable pipe fixing device for ultrasonic flaw detection includes a base plate 1 and a fixing frame 11: the base plate 1 is provided with an extension support mechanism inside, a central column 6 is provided at the upper end of the base plate 1, a height adjustment mechanism is provided inside the central column 6, a fixing frame 11 is provided at the upper end of the height adjustment mechanism, a roller 12 is provided inside the fixing frame 11, and a limit mechanism is provided on both sides of the fixing frame 11.

[0029] The extension support mechanism includes a slide groove 2 and an extension support plate 4. The slide groove 2 is opened at an equal angle inside the base plate 1. The extension support plate 4, which is in the shape of a "Z", is slidably arranged inside the slide groove 2. A limiting groove for the extension support plate 4 is opened at the upper end of the slide groove 2.

[0030] When the device is not in use, the extension support plate 4 is inserted into the slide groove 2 to fold and store it. When the device is in normal use, the extension support plate 4 is moved to the outermost position. As the bottom surface of the extension support plate 4 and the bottom surface of the base plate 1 simultaneously contact the ground, the extension support plate 4 will rotate, causing the upper end of the extension support plate 4 to be inserted into the limiting groove, thereby fixing the extension support plate 4 and preventing it from moving inward. The slide groove 2 also limits the extension support plate 4, preventing it from moving outward. Gravity is used to fix the extension support plate 4 and the slide groove 2.

[0031] The slide 2 is equipped with a locking block 3 inside, and the corner of the extension support plate 4 is provided with a corresponding locking groove 5.

[0032] When the extension support plate 4 is stored, the slot 5 will engage with the block 3 to fix the extension support plate 4, and the extension support plate 4 can then be used to support the device.

[0033] The height adjustment mechanism includes a worm 7, a worm wheel 8, a lead screw 9, and a support column 10. The worm 7 is rotatably disposed inside the central column 6. The worm wheel 8 is disposed on the outer side of the worm 7 and is rotatably disposed inside the central column 6. The lead screw 9 is disposed at the upper end of the worm wheel 8. The support column 10 is disposed on the outer side of the lead screw 9 and is slidably disposed inside the central column 6. The lead screw 9 is rotatably disposed inside the central column 6.

[0034] When the device is in use, the worm gear 7 can be rotated to drive the worm wheel 8 to rotate. However, the worm wheel 8 cannot drive the worm gear 7 to rotate. Therefore, when the device is not adjusted, it can self-lock. The lead screw 9 will rotate with the worm wheel 8. When the lead screw 9 rotates, since the lead screw 9 and the support column 10 are threadedly connected, and the central column 6 will limit the support column 10, the support column 10 can only move up and down. Therefore, the height of the support column 10 will be adjusted, thereby adjusting the overall height of the device.

[0035] A motor is provided on the side of the roller 12, and the motor is located inside the fixed frame 11.

[0036] The roller 12 is driven to rotate by a motor. When the roller 12 rotates, it will drive the pipe on its surface to rotate, thereby adjusting the position of the pipe. At the same time, the roller 12 can be replaced to make the surface texture of the roller 12 different, thereby changing the direction of the friction force on the pipe when the roller 12 rotates. This allows for adjustment of the pipe's position and angle, facilitating ultrasonic testing of different parts of the pipe.

[0037] The limiting mechanism includes a limiting frame 13 and a fixing bolt 14. The limiting frame 13 is arc-shaped and is slidably disposed inside the fixing frame 11 and fixed by the fixing bolt 14.

[0038] When the device is in use, the length of its extension can be adjusted by moving the limit bracket 13, and then the limit bracket 13 can be fixed by using the fixing bolt 14.

[0039] An electric push rod 15 is provided at the end of the limiting frame 13 away from the fixed frame 11. The extended end of the electric push rod 15 is rotatably connected to a support frame 16. A roller 17 is rotatably provided inside the support frame 16.

[0040] When the device is in use, the support frame 16 and roller 17 can limit the pipe. When the pipe rotates, the support frame 16 and roller 17 will also rotate under the action of friction, thereby preventing the support frame 16 and roller 17 from obstructing the rotation of the pipe, thus facilitating the detection of different positions of the pipe.
