Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting detection, in particular to an ultrasonic flaw detection device for pipe fittings. Background Art

[0002] Pipe fittings play the role of connection, control, direction change, diversion, sealing, support, etc. in pipeline systems. After production, ultrasonic flaw detection equipment will be used to inspect the pipe fittings.

[0003] At present, when ultrasonic flaw detection equipment detects pipe fittings, it will extend the probe into the pipe fittings, clamp the pipe fittings through the clamping assembly, and detect the pipe fittings through the ultrasonic flaw detection equipment. At present, the clamping equipment squeezes and limits the pipe fittings through two limit plates. However, excessive squeezing force of the limit plates will cause deformation of the pipe fittings, and the pipe fittings do not have the disadvantage of automatic rebound, which causes the pipe fittings to be damaged and unusable, thereby causing excessive consumption of pipe fitting resources. In addition, after the initial inspection of the pipe fittings, the inspection direction of the pipe fittings needs to be adjusted. At present, when adjusting the pipe fittings, the pipe fittings are removed from the clamping assembly, and the pipe fittings are manually turned over, and the pipe fittings are limited by the clamping assembly again. This inspection method not only prolongs the processing time, but also affects the efficiency of pipe fitting inspection. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A pipe ultrasonic flaw detection device comprises a base 1, an ultrasonic flaw detection display screen 5, and a probe 6. A bracket 1 2 and a bracket 2 3 are fixedly mounted on the base 1, respectively. The bracket 1 2 and the bracket 2 3 are respectively arranged at two sides of the base 1. A guide block 22 is provided in a sliding sleeve in the base 1, and a cylinder 23 connected to the guide block 22 is fixedly mounted in the base 1. A support 24 is fixedly mounted on the guide block 22, and a fixing rod 25 and a limiting rod 26 are fixedly mounted on the support 24, respectively. A holder 4 for supporting the pipe is provided in a sliding sleeve on the limiting rod 26;

[0023] A symmetrically arranged slider 27 is slidably sleeved on the fixed rod 25, and a traction rod 29 is connected between the slider 27 and the base 4. A connecting plate is fixedly installed on the slider 27, and a telescopic rod 28 connected to the connecting plate is fixedly installed on the support 24. The fixed rod 25 is horizontally arranged, and the limit rod 26 is vertically arranged. Both ends of the traction rod 29 are pin-connected to the slider 27 and the base 4 respectively.

[0024] The movement of the cylinder 23 enables the holder 4 to support pipes of different lengths when it moves. The output ends of the two telescopic rods 28 are moved, so that the connecting plate drives the slider 27 to slide on the fixed rod 25. The slider 27 pulls the traction rod 29 to deflect when it moves. When the traction rod 29 deflects, it can pull the holder 4 to move up and down with the limit rod 26 as the fulcrum, so that when the holder 4 supports the pipe, the center hole of the pipe can correspond to the probe 6;

[0025] The pipe fitting can be supported and guided by the holder 4, a driving rod 7 is rotatably mounted on the bracket 2, and the probe 6 is arranged on the driving rod 7;

[0026] A limiting assembly for limiting the position of the pipe is installed on the driving rod 7;

[0027] The drive rod 7 is integrally connected with a sleeve 8, and a motor 10 is fixedly installed in the sleeve 8. A bidirectional screw rod 11 is fixedly connected to the output end of the motor 10, and two matching nuts 12 are slidably sleeved on the bidirectional screw rod 11.

[0028] A contact plate 14 that movably contacts the inner wall of the pipe is provided in the sleeve 8, and a connecting rod 13 is connected between the contact plate 14 and the nut 12. The driving rod 7 and the bidirectional screw 11 are both arranged horizontally, and the two ends of the connecting rod 13 are respectively connected with the nut 12 and the contact plate 14 by pins. A guide long hole for guiding the connecting rod 13 is provided on the sleeve 8, and the guide long hole guides and limits the connecting rod 13, thereby limiting the moving direction of the nut 12.

[0029] The position difference generated by the deflection of the two connecting rods 13 through the drive of the motor 10 can pull the contact plate 14, so that the three contact plates 14 can contact the inner wall of the pipe fitting, and the contact plate 14 limits the pipe fitting from the inner wall of the pipe fitting, so that the pipe fitting will not be deformed after being limited;

[0030] A driving assembly for driving the driving rod 7 is installed on the bracket 1 2;

[0031] The driving assembly includes a gear 9 fixedly mounted on the driving rod 7, a motor 2 15 fixedly mounted on the bracket 1 2, a rotating shaft 16 connected to the driving rod 7 in transmission is fixedly connected to the output end of the motor 2 15, the rotating shaft 16 is horizontally arranged below the driving rod 7, and an incomplete gear 17 meshing with the gear 9 is fixedly mounted on the rotating shaft 16. The detection direction of the probe 6 is changed by the driving of the motor 2 15, so that the detection direction of the probe 6 can be quickly adjusted according to the position of the pipe fitting, so that the pipe fitting does not need to be manually turned over when the detection position is changed, which not only reduces the time consumed by the pipe fitting detection, but also improves the efficiency of the pipe fitting detection;

[0032] A telescopic rod 18 is fixedly installed in the bracket 2 3, and a pressure plate 19 that is movably opposed to the pipe fitting is fixedly connected to the output end of the telescopic rod 18. A guide rod 20 extending into the pipe fitting is rotatably installed on the pressure plate 19, and a soft cushion 21 that is movably opposed to the inner wall of the pipe fitting is provided on the guide rod 20. The guide rod 20 supports and guides the pipe fitting, so that the pipe fitting will not turn over or fall off when being tested;

[0033] It should be noted that the specific models and specifications of the ultrasonic flaw detection display screen 5, probe 6, motor 1 10, motor 2 15, telescopic rod 1 18, cylinder 23, and telescopic rod 2 28 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0034] The functional principle of the utility model can be explained through the following operation modes:

[0035] The cylinder 23 is activated according to the length of the pipe, so that the cylinder 23 drives the guide block 22 to slide in the base 1. When the guide block 22 slides, it drives the support 24, the limit rod 26 and the clamping seat 4 to move, so that the clamping seat 4 can move to the position below the pipe;

[0036] The telescopic rod 28 is activated according to the height of the pipe, and the telescopic rod 28 drives the connecting plate to slide in the support 24, and the connecting plate drives the slider 27 to slide on the fixed rod 25. When the slider 27 moves, the traction rod 29 is pulled to deflect. The position difference generated when the traction rod 29 deflects can drive the holder 4 to slide on the limit rod 26, so that the holder 4 can move to the position below the pipe and support the pipe, so that the center position of the pipe can correspond to the probe 6;

[0037] The output end of the telescopic rod 18 drives the pressure plate 19 and the guide rod 20 to move. When the guide rod 20 extends to the left end of the pipe fitting, the pressure plate 19 can resist the pipe fitting, so that the pipe fitting can move with the holder 4 as a fulcrum, and the cushion 21 on the guide rod 20 can contact the inner wall of the pipe;

[0038] When the pipe is moved on the holder 4, the right end of the pipe can extend to the probe 6;

[0039] When the probe 6 moves to the specified position of the pipe, the right end of the pipe can move onto the sleeve 8, and the telescopic rod 18 stops running;

[0040] The output end of the motor 10 drives the bidirectional screw 11 to rotate. When the bidirectional screw 11 rotates, the two nuts 12 move toward each other. When the two nuts 12 move toward each other, the traction connecting rod 13 deflects in the guide long hole. When the connecting rod 13 deflects, it drives the three contact plates 14 to move against the inner wall of the pipe fitting.

[0041] After the contact plate 14 limits the position of the pipe, the motor 10 is turned off;

[0042] The cooperation between the probe 6 and the ultrasonic flaw detection display screen 5 can detect the pipe fittings;

[0043] When the pipe inspection is completed, the output end of the motor 10 drives the bidirectional screw 11 to rotate in the opposite direction, so that the contact plate 14 is disconnected from the pipe, and the output end of the motor 2 15 drives the rotating shaft 16 to rotate one circle. The rotating shaft 16 drives the driving rod 7 to rotate through the meshing incomplete gear 17 and the gear 9. When the driving rod 7 rotates, it can drive the probe 6 to rotate, and the guide rod 20 can support the pipe;

[0044] The rotating shaft 16 rotates one circle, causing the driving rod 7 to rotate to a certain angle. The driving rod 7 drives the direction of the probe 6 to change during the rotation, and the pipe is again stopped by the contact plate 14, so that the probe 6 can fully detect the pipe.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
