Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a pipeline butt joint process detection device. Background Art

[0002] Ultrasonic flaw detection is a nondestructive testing method that uses the difference in acoustic properties of materials and their defects to reflect the ultrasonic propagation waveform and the energy change of the penetration time to inspect the internal defects of the material. After the pipeline is welded, it is necessary to use ultrasonic nondestructive testing to check whether there are gaps and bubbles inside the weld. This is to avoid cracks or gaps at the joint of the pipeline, to prevent leakage or insufficient strength of the pipeline, and to prevent easy rupture.

[0003] The patent document with announcement number: CN218726923U discloses "an ultrasonic detection device for pipe butt welds", which involves inserting two pipes into a fixed pipe respectively, fixing the pipes with a clamp, connecting the two pipes by rotating an adjusting member, and starting a driving member to drive the fixed pipe to rotate, so that workers can conveniently weld the pipes, thereby improving the work efficiency of the workers.

[0004] Although the device achieves the purpose of fixing the pipeline through the clamping piece, it is inconvenient to determine the moving distance of each clamping rod. If the moving distance of the clamping rod at one fixed pipe is different from the moving distance of the clamping rod at another fixed pipe, it will cause the horizontal axes of the pipelines in the two fixed pipes to be different, thereby affecting the subsequent welding and detection work. Therefore, it is necessary to provide an easy-to-use pipeline docking process detection device to solve the above technical problems. Utility Model Content

[0022] As a technical optimization scheme of the utility model, the adjustment mechanism 2 includes a forward and reverse screw rod 201, one end of the forward and reverse screw rod 201 is rotatably matched with the inner wall of the base 1, and the outer sides of the forward and reverse screw rod 201 are respectively threadedly connected with a first moving block 202 and a second moving block 203, the bottom of the left moving plate 3 and the connecting plate 4 are both welded and fixed with the first moving block 202, and the bottom of the right moving plate 3 and the connecting plate 4 are both welded and fixed with the second moving block 203.

[0025] In this embodiment, by providing the limiting track 204, the first moving block 202 and the second moving block 203 can be limited, thereby improving the stability of the first moving block 202 and the second moving block 203 during use.

[0026] As a technical optimization solution of the utility model, a stabilizing block 10 is sleeved on the outer side of the forward and reverse screw rods 201 , and the outer side of the stabilizing block 10 is fixedly connected to the inner wall of the base 1 .

[0027] In this embodiment, by providing the stabilizing block 10 , an auxiliary supporting effect can be provided to the forward and reverse screw rods 201 , thereby improving the stability of the forward and reverse screw rods 201 .

[0028] As a technical optimization solution of the utility model, the auxiliary mechanism 5 includes an auxiliary ring 501, the center point of the auxiliary ring 501 is in the same horizontal plane as the center points of the first fixed tube 7 and the second fixed tube 8, the bottom of the auxiliary ring 501 is fixedly connected to the top of the connecting plate 4, a floating rod 502 is inserted into the top of the auxiliary ring 501, a connecting ring 503 is fixedly connected to the outer side of the floating rod 502, a spring 504 is welded to the top of the connecting ring 503, and one end of the spring 504 is welded to the top of the inner cavity of the auxiliary ring 501.

[0029] In this embodiment: when the pipe rotates inside the auxiliary ring 501, if the center point of the pipe is at a different position from the center point of the auxiliary ring 501, the pipe will cause the floating rod 502 to move up or down during the rotation. The user can determine whether the center point of the pipe is the same as the center point of the auxiliary ring 501 by the position of the floating rod 502, thereby improving the welding accuracy of the pipe.

[0030] As a technical optimization solution of the utility model, the fixing mechanism 9 includes a fixing block 901, the top and bottom of the first fixing tube 7 and the second fixing tube 8 are fixedly connected with the fixing block 901, the inner cavity of the fixing block 901 is threadedly connected with a fixing rod 902, one end of the fixing rod 902 is rotatably matched with a fixing hoop 903, the outer side of the fixing hoop 903 is fixedly connected with a scale rod 904, and the outer side of the scale rod 904 is slidably connected to the inner cavity of the first fixing tube 7 and the second fixing tube 8.

The user can observe the scale lines on the outside of each scale rod 904 to determine the moving distance of the fixing rod 902, so as to adjust the moving distance of each fixing rod 902 to make the moving distance of each fixing rod 902 the same, thereby ensuring that the center points of the pipelines in the first fixed tube 7 and the second fixed tube 8 are the same.

[0032] The working principle of a pipeline butt joint process detection device provided by the utility model is as follows:

[0033] When using the device, the pipes to be welded are respectively inserted into the first fixed pipe 7 and the second fixed pipe 8, and then the pipes are continued to be moved so that one end of the pipes is inserted into the auxiliary ring 501 and part of the pipes are extended for docking. Then the user can drive the fixing hoop 903 to move by rotating the fixing rod 902. The fixing hoop 903 is pressed against the outside of the pipe to fix the pipe, and when the fixing hoop 903 moves, the scale rod 904 is also driven to move synchronously. The user can observe the scale lines on the outside of each scale rod 904 to determine the moving distance of the fixing rod 902, so as to adjust the moving distance of each fixing rod 902 to make the moving distance of each fixing rod 902 the same, thereby ensuring that the center points of the pipes in the first fixed pipe 7 and the second fixed pipe 8 are the same. After the pipes are fixed, the hand crank at one end of the forward and reverse screw rods 201 is rotated. The wheel can rotate the forward and reverse screw rods 201. The rotation of the forward and reverse screw rods 201 can make the first moving block 202 and the second moving block 203 move toward each other, thereby driving the two moving plates 3 and the connecting plate 4 to move, and then the welding ends of the two pipes can be connected. Then, the first fixed pipe 7 can be driven to rotate by the driving member 6, thereby driving the pipe to rotate, which is convenient for welding. During the rotation of the pipe, if the center point of the pipe is at a different position from the center point of the auxiliary ring 501, the pipe will cause the floating rod 502 to move up or down during the rotation. The user can determine whether the center point of the pipe is the same as the center point of the auxiliary ring 501 through the position of the floating rod 502, thereby further improving the welding accuracy of the pipe. After welding is completed, the ultrasonic detection head 12 is driven to move by the electric cylinder 11, so that the ultrasonic detection head 12 abuts against the welded pipe, thereby detecting the weld.
