Description

Technical Field

[0001] This utility model relates to the field of steel pipe surface inspection technology, and in particular to a steel pipe hot expansion surface inspection device. Background Technology

[0002] Hot expansion of steel pipes is a steel pipe processing technology that refers to the process of expanding the diameter of a small steel pipe by heating it to achieve a larger diameter. During the hot expansion process, the steel pipe undergoes high-temperature heating and mechanical deformation, which may cause or aggravate the original defects on the surface of the steel pipe, such as cracks, pores, inclusions, etc. Therefore, after hot expansion, the surface of the steel pipe needs to be inspected using testing equipment to control the quality of the product. However, most of the existing testing equipment used for surface inspection of steel pipes after hot expansion still has problems that need to be solved.

[0003] Most existing testing equipment requires staff to hand-hold a flaw detector to inspect steel pipes. During the inspection process, the flaw detector needs to be moved constantly to perform a comprehensive inspection of the steel pipe. This operation is cumbersome, time-consuming, and labor-intensive, affecting the inspection efficiency and increasing the workload of staff to some extent. Therefore, it is necessary to design a surface inspection device for hot-expanded steel pipes to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface inspection device for hot expansion processing of steel pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surface inspection device for hot-expanded steel pipes includes a base. Two first bearing seats are fixedly connected to the top of the base. The inner walls of the inner rings of the bearings on both first bearing seats are fixedly connected to the same drive screw. A screw nut is fitted onto the drive screw, and the screw nut is adapted to the drive screw. A movable plate is fixedly connected to the outer wall of the screw nut. A mounting plate is provided on the top of the movable plate, and a flaw detector is fixedly connected to the top of the mounting plate. A first rotating shaft is fixedly connected to one side of the drive screw. Two first synchronous pulleys and two second synchronous pulleys are provided on the side of the drive screw near the first rotating shaft. The same first synchronous belt is fitted onto each of the two first synchronous pulleys, and the same second synchronous belt is fitted onto each of the two second synchronous pulleys. The first and second synchronous pulleys at the bottom are fitted onto the first rotating shaft and fixedly connected to the outer wall of the first rotating shaft. A second rotating shaft passes through the first and second synchronous pulleys at the top and is fixedly connected to the second rotating shaft. The two ends of the base... Two second bearing seats are fixedly connected to the top of each component. The inner walls of the bearings on the two second bearing seats at the same end are fixedly connected to the same roller shaft. Two second rotating shafts are respectively fixedly connected to two roller shafts. Anti-slip pads are fixedly connected to the outer walls of the roller shafts. Because the moving flaw detector allows the steel pipe to rotate, the roller shaft rotates along with the flaw detector, causing the anti-slip pads to rotate, which in turn causes the steel pipe to rotate. This allows the moving flaw detector to perform a comprehensive inspection of the steel pipe's surface. This effectively solves the problem mentioned in the background art, where most existing inspection equipment requires operators to hold the flaw detector and constantly move it to perform a comprehensive inspection, making the operation cumbersome, time-consuming, and labor-intensive, affecting inspection efficiency and increasing the workload of operators. This solution achieves the technical effect of simple operation, facilitating comprehensive inspection of the steel pipe's surface, effectively reducing the time and effort required for inspection, improving inspection efficiency, and reducing the workload of operators.

[0007] Preferably, a first gear is fixedly connected to one side of the first rotating shaft, a second gear is meshed with the first gear, a motor is provided on one side of the second gear, the motor is fixedly connected to the base, and the output end of the motor is fixedly connected to the second gear.

[0008] Preferably, two first fixing plates are fixedly connected to both ends of the top of the base. The two first fixing plates at the same end are fixedly connected to the same guide rod on the side that is close to each other. Both guide rods pass through the movable plate, and the movable plate is slidably connected to the guide rod.

[0009] Preferably, the top of the base is fixedly connected to two second fixing plates, and a baffle is fixedly connected to one side of each of the two second fixing plates.

[0010] Preferably, the bottom of the baffle is provided with a roller, the roller is fitted with a mounting base, and the mounting base is fixedly connected to the top of the mounting plate.

[0011] Preferably, the mounting plate has four positioning holes, and each of the four positioning holes is provided with a positioning rod, which is adapted to the positioning hole.

[0012] Preferably, all four positioning rods are fixedly connected to the top of the movable plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] Because the mobile flaw detector utilizes a technique that allows the steel pipe to rotate during operation, the rollers rotate along with the flaw detector, which in turn drives the anti-slip pads to rotate, and the anti-slip pads in turn drive the steel pipe to rotate. This allows the mobile flaw detector to perform a comprehensive inspection of the steel pipe's surface. This effectively solves the problem mentioned in the background section: most existing inspection equipment requires operators to hold the flaw detector and constantly move it during the inspection process to achieve a comprehensive inspection, which is cumbersome, time-consuming, and labor-intensive, affecting inspection efficiency and increasing the workload of operators. Therefore, this technology simplifies operation, facilitates comprehensive surface inspection of steel pipes, effectively reduces the time and effort required for inspection, improves inspection efficiency, and reduces the workload of operators.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A surface inspection device for hot-expanded steel pipes includes a base 1. Two first bearing seats 2 are fixedly connected to the top of the base 1. The inner walls of the inner rings of the bearings on both first bearing seats 2 are fixedly connected to the same drive screw 3. A screw nut 4 is fitted onto the drive screw 3, and the screw nut 4 is compatible with the drive screw 3. A movable plate 5 is fixedly connected to the outer wall of the screw nut 4. A mounting plate 6 is provided on the top of the movable plate 5. A flaw detector 7 (an ultrasonic flaw detector) is fixedly connected to the top of the mounting plate 6. A first rotating shaft 8 is fixedly connected to one side of the drive screw 3. The drive screw 3 is positioned near the first... Two first synchronous pulleys 9 and two second synchronous pulleys 11 are provided on one side of a rotating shaft 8. The same first synchronous belt 10 is fitted onto each of the two first synchronous pulleys 9, and the same second synchronous belt 12 is fitted onto each of the two second synchronous pulleys 11. The first synchronous pulleys 9 and 11 at the bottom are both fitted onto the first rotating shaft 8 and are fixedly connected to the outer wall of the first rotating shaft 8. A second rotating shaft 13 passes through the first synchronous pulleys 9 and 11 at the top, and the first synchronous pulleys 9 and 11 at the top are fixedly connected... Connecting to the second rotating shaft 13, two second bearing seats 16 are fixedly connected to the top of both ends of the base 1. The inner walls of the bearings on the two second bearing seats 16 at the same end are fixedly connected to the same roller shaft 14. The two second rotating shafts 13 are respectively fixedly connected to the two roller shafts 14. The outer walls of the roller shafts 14 are fixedly connected to anti-slip pads 15. Since the technology of moving the flaw detector allows the steel pipe to rotate, the roller shaft will rotate with the flaw detector, which will drive the anti-slip pad to rotate, and the anti-slip pad will drive the steel pipe to rotate. The moving flaw detector can then perform a comprehensive inspection of the surface of the steel pipe. This effectively solves the problem mentioned in the background technology that most of the existing inspection equipment requires the operator to hold the flaw detector to inspect the steel pipe. During the inspection process, the flaw detector needs to be moved constantly to perform a comprehensive inspection of the steel pipe. The operation is relatively troublesome, requires a lot of time and effort, affects the inspection efficiency, and increases the workload of the operator to a certain extent. This achieves the technical effect of simple operation, convenient comprehensive inspection of the surface of the steel pipe, effectively reducing the time and effort required for inspection, improving inspection efficiency, and reducing the workload of the operator.

[0023] In this utility model, a first gear 17 is fixedly connected to one side of the first rotating shaft 8, and a second gear 18 is meshed with the first gear 17. A motor 19 is provided on one side of the second gear 18, and the motor 19 is fixedly connected to the base 1. The output end of the motor 19 is fixedly connected to the second gear 18.

[0024] In this utility model, two first fixing plates 20 are fixedly connected to both ends of the top of the base 1. The two first fixing plates 20 at the same end are fixedly connected to the same guide rod 21 on the side that is close to each other. Both guide rods 21 pass through the moving plate 5. The moving plate 5 moves along the guide rod 21 to ensure the stability of the moving plate 5 when it moves. The moving plate 5 is slidably connected to the guide rod 21.

[0025] In this utility model, the top of the base 1 is fixedly connected to two second fixing plates 22, and a baffle 23 is fixedly connected to one side of each of the two second fixing plates 22.

[0026] In this utility model, a roller 24 is provided at the bottom of the baffle 23, and a mounting seat 25 is sleeved on the roller 24. The mounting seat 25 is fixedly connected to the top of the mounting plate 6. Before the flaw detector 7 is installed, the side of the mounting plate 6 near the second fixed plate 22 and the side of the baffle 23 away from the second fixed plate 22 are not on the same vertical plane.

[0027] In this utility model, the mounting plate 6 has four positioning holes 26, and each of the four positioning holes 26 is provided with a positioning rod 27, which is adapted to the positioning hole 26.

[0028] In this utility model, the four positioning rods 27 are all fixedly connected to the top of the movable plate 5. The positioning hole 26 and the positioning rod 27 cooperate to facilitate the positioning and installation of the flaw detector 7.

[0029] Working principle: When installing the flaw detector 7, align the positioning hole 26 with the positioning rod 27, and place the mounting plate 6 on the positioning rod 27 to position the flaw detector 7. Place the steel pipe to be inspected on the two anti-slip pads 15, connect the external power supply, and start the motor 19 and the flaw detector 7. The output end of the motor 19 will drive the first rotating shaft 8 to rotate, which in turn drives the drive screw 3 to rotate. The drive screw 3 will then drive the screw nut 4 to move, which in turn drives the moving plate 5 to move. The moving plate 5 will move along the guide rod 21 to ensure stability during movement. The movement of the moving plate 5 will also drive the positioning rod 27 to move, which in turn drives the mounting plate 6 to move, which in turn drives the flaw detector 7 to move, inspecting the surface of the steel pipe. During the rotation of the first rotating shaft 8, the first synchronous pulley 9 and the second synchronous pulley 11 will also rotate. The first synchronous pulley 9 and the second synchronous pulley 11 will then drive the first synchronous belt 10 and the second synchronous belt 12 to rotate. A synchronous belt 10 and a second synchronous belt 12 can drive another first synchronous pulley 9 and a second synchronous pulley 11 to rotate. The first synchronous pulley 9 and the second synchronous pulley 11 will drive the second rotating shaft 13 to rotate, the second rotating shaft 13 will drive the roller shaft 14 to rotate, and the roller shaft 14 will drive the anti-slip pad 15 to rotate. The two anti-slip pads 15 rotate in the same direction, which can drive the steel pipe to rotate. Thus, the steel pipe can be rotated during the movement of the flaw detector 7 to perform a comprehensive inspection of the surface of the steel pipe. After the inspection is completed, the steel pipe is removed, and the output end of the motor 19 is rotated in the opposite direction, which can move the flaw detector 7 back to the initial position. When the mounting plate 6 moves, it will also drive the mounting seat 25 to move. The mounting seat 25 will drive the roller 24 to move. The roller 24 will move to the bottom of the baffle 23 and contact the bottom of the baffle 23, which can limit the position of the roller 24, fix the position of the mounting seat 25, fix the position of the mounting plate 6, and install the flaw detector 7.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
