[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a cold-bent steel pipe weld detection device includes: an adjusting mechanism 1, the adjusting mechanism 1 includes a base 11, fixed shells 12 are provided on both sides of the top of the base 11, and one side of the two fixed shells 12 is fixedly connected to a motor 13, and two bidirectional screws 14 are provided inside the two fixed shells 12. The bottom of the fixed shell 12 is welded to the top of the base 11, and one side of the motor 13 is docked with the top of the base 11. The output end of the motor 13 passes through one side of the fixed shell 12 and docks with one end of the bidirectional screw 14. The ends of the two bidirectional screws 14 away from the motor 13 are provided with a bearing seat 15, and the other end of the bidirectional screw 14 is fixedly connected to the inner surface of the bearing seat 15. The side of the bearing seat 15 away from the bidirectional screw 14 is fixedly connected to the side of the inner wall of the fixed shell 12 away from the motor 13. Moving blocks 16 are provided on different threaded portions on the outer surfaces of the two bidirectional screws 14, and clamping rings 17 are provided on the tops of the four moving blocks 16. One side of the clamping ring 17 is opened The inner walls of the slots are all provided with fixed tubes 18, and different threaded parts on the outer surface of the bidirectional screw 14 are all threadedly connected with moving blocks 16, and the top of the moving block 16 is fixedly connected with a clamping ring 17, and the inner walls of the slots opened on one side of the clamping ring 17 are fixedly connected with the fixed tubes 18, and a spring 19 is provided inside the fixed tube 18, and a movable tube 110 is provided at one end of the spring 19, and a pulley 111 is provided at the end of the movable tube 110 away from the spring 19, one end of the spring 19 is fixedly connected to the end of the inner wall of the fixed tube 18 away from the movable tube 110, and the other end of the spring 19 is fixedly connected to the end of the movable tube 110 away from the pulley 111, and a detection pile 112 is provided between the two fixed shells 12, the outer surface of the movable tube 110 is slidably connected to the inner wall of the fixed tube 18, and the end of the movable tube 110 away from the spring 19 is connected to the pulley 111, and the bottom of the detection pile 112 is fixedly connected to the top of the base 11, and a limiting mechanism 2 is provided on one side of the top of the base 11.
[0023] In this embodiment, when the staff uses the weld detection device to detect the cold-bent steel pipe, the motor 13 is first driven according to the thickness of the cold-bent steel pipe, and then the motor 13 will drive the bidirectional screw 14 to rotate, so that the moving block 16 and the clamping ring 17 will be moved. When the two clamping rings 17 are adjusted to a suitable spacing, the cold-bent steel pipe is placed between the clamping rings 17, and the motor 13 is started again to clamp and fix the cold-bent steel pipe by the two clamping rings 17 to avoid loosening and falling off of the cold-bent steel pipe during the detection process. At the same time, the pulley 111 will contact the outer surface of the cold-bent steel pipe. The advantage is that when the cold-bent steel pipe needs to detect the welding conditions of the remaining parts, the contact between the pulley 111 and the cold-bent steel pipe can easily move the cold-bent steel pipe to be detected. The detection part is moved to the detection pile 112 for detection, which saves the time and energy of the staff. In addition, it can also protect the outer surface of the cold-bent steel pipe from damage.
[0024] like Figure 1 and Figure 4 As shown, the limiting mechanism 2 includes a limiting plate 21 , a buffer pad 22 is fixedly connected to one side of the limiting plate 21 close to the fixed shell 12 , and mounting members 23 are fixedly connected to both sides of the limiting plate 21 . The mounting members 23 are fixed to the base 11 by bolts 24 .
[0025] In this embodiment, the limit plate 21 can limit the cold-bent steel pipe from moving too much during the welding detection process and out of the detection range of the equipment. When it is necessary to detect a longer cold-bent steel pipe, the bolt 24 can be removed by tools, and then the limit plate 21 can be removed, thereby avoiding the limit plate 21 from affecting the welding detection of the longer cold-bent steel pipe.
[0026] The utility model provides a cold-bent steel pipe weld detection device, the specific working principle is as follows:
[0027] When the staff use the weld inspection device to inspect the cold-bent steel pipe, they first need to drive the motor 13 according to the thickness of the cold-bent steel pipe, and then the motor 13 drives the bidirectional screw 14 to rotate, so that the moving block 16 and the clamping ring 17 are moved. When the two clamping rings 17 are adjusted to an appropriate spacing, the staff places the cold-bent steel pipe between the clamping rings 17. In order to avoid the loosening and falling off of the cold-bent steel pipe during the inspection process, the staff needs to start the motor 13 again to clamp and fix the cold-bent steel pipe with the two clamping rings 17. In this way, the cold-bent steel pipe can be stably maintained between the clamping rings 17 to ensure the smooth progress of the inspection process. At the same time, the pulley 111 will contact the outer surface of the cold-bent steel pipe. The advantage of this design is that when inspection is required When checking the welding conditions of other parts of the cold-bent steel pipe, the staff can easily move the part of the cold-bent steel pipe to be inspected to the inspection pile 112 for inspection through the contact between the pulley 111 and the cold-bent steel pipe. This not only saves the staff's time and energy, but also protects the outer surface of the cold-bent steel pipe from damage. In addition, the limit plate 21 plays an important role in the welding inspection process. It can effectively limit the movement range of the cold-bent steel pipe to prevent it from moving too much during the inspection process and causing it to be out of the inspection range of the equipment. The staff can remove the bolts 24 that fix the limit plate 21 by using specific tools. In this way, the limit plate 21 can be easily removed, thereby avoiding it from causing unnecessary influence on the longer cold-bent steel pipe during the welding inspection process.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
