Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic detection, and in particular to a weld detection device for electromechanical equipment. Background Art

[0002] Inspecting welds in electromechanical equipment ensures the structural safety and operational reliability of the equipment. As a critical load-bearing and sealing feature of the equipment, weld quality directly impacts overall mechanical performance. Inspections can identify defects such as cracks, pores, and lack of fusion, preventing structural failure or leakage caused by stress concentration. They also verify that welding procedures are qualified and meet industry safety standards. Using techniques such as nondestructive testing can prevent potential safety hazards, extend equipment service life, reduce economic losses from unplanned downtime, and provide a scientific basis for equipment lifecycle management.

[0003] Existing methods for inspecting welds in electromechanical equipment include ultrasonic probing. However, because this process requires moving the ultrasonic probe along the workpiece surface coated with coupling agent, bumps, metal slag, or recessed areas in some weld areas can lead to uneven coupling agent application, resulting in gaps at the bottom of the ultrasonic probe and compromising the integrity of the resulting ultrasonic probe image. Furthermore, manual application of the coupling agent is difficult, time-consuming, and labor-intensive, and can easily result in uneven application. Automated application also lacks the flexibility to adjust according to the actual width of the weld. Summary of the Invention

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides the following technical solutions: a device for detecting welds of electromechanical equipment, comprising a detection device body, the detection device body comprising a detection platform 1, a support frame 5, a cleaning mechanism 6 and a coupling agent delivery assembly 7, end plates 4 are welded at both ends of the surface of the detection platform 1, a first motor 8 is screwed to the outer side of one of the end plates 4, a screw rod 9 is inserted at the output end of the first motor 8, a threaded sleeve 18 is sleeved on the surface of the screw rod 9, and the threaded sleeve 18 is welded to the surface of the support frame 5, a lifting slot 2 is provided at the bottom of the detection platform 1, and the detection The surface of the test platform 1 is mounted with a lifting plate 3. A slag removal frame 11 is provided at one end of the support frame 5, with a grinding plate 35 mounted inside the slag removal frame 11. A detection frame 12 is integrally formed at the other end of the support frame 5. A connecting post 19 is inserted into the bottom of the detection frame 12, and an ultrasonic probe 20 is screwed to the bottom of the connecting post 19. A coupling agent delivery assembly 7 is mounted at the middle bottom of the support frame 5. The ultrasonic probe 20, the bottom of the cleaning mechanism 6, and the bottom of the coupling agent delivery assembly 7 are all used to press against the surface of the weld to be tested. This weld detection device is used to detect and process planar weld areas on the surface of plate-type workpieces in electromechanical equipment using ultrasound.

[0029] When the present invention is used, the workpiece to be measured is placed on the surface of the lifting plate 3. After the electric lifting rod at the bottom is started, the lifting plate 3 together with the workpiece placed on the surface can be lifted up until it touches the bottom of the support frame 5. The welding surface of the workpiece to be measured is pressed with the help of the grinding plate 35, the cleaning mechanism 6, the coupling agent delivery assembly 7 and the ultrasonic probe 20. Then, the first motor 8 is started, and the screw rod 9 is driven to rotate by the first motor 8, thereby controlling the entire support frame 5 to move along the surface of the welding surface to be measured. The cleaning mechanism 6 is used to grind and clean the welding surface of the moved area in advance, and the debris generated by grinding is removed with the help of the slag removal frame 11. Then, the coupling agent solution is applied to the surface of the welding surface to be measured by the coupling agent delivery assembly 7. Finally, the ultrasonic probe 20 can be used to complete the detection purpose of the welding area. In this process, the slag removal frame 11 is also used to detect whether there is a depression in the welding area.

[0030] In this embodiment, the support frame 5 has an integrally formed column 15 at its center bottom. The coupling agent delivery assembly 7 includes a coupling agent tank 16 and a coating mechanism 17. The end of the screw rod 9 is embedded in the interior of the end plate 4 via a bearing. The top of the slag removal frame 11 has an integrally formed top plate 10. An electric lifting rod is screwed into the interior of the lifting trough 2, and the bottom surface of the lifting plate 3 is screwed to the top of the electric lifting rod. The lifting plate 3 is used to lift the workpiece to be tested upward. A saw blade is provided at the edge of the grinding plate 35.

[0031] Specifically, after starting the first motor 8, the first motor 8 drives the screw 9 to rotate. Since the top of the support frame 5 is sleeved on the surface of the screw 9 through two threaded sleeves 18, it can directly drive the entire support frame 5 to move horizontally, so that the slag removal frame 11 and the detection frame 12 at both ends of the support frame 5 can move along the straight weld. During the movement, pre-grinding is completed with the help of the grinding plate 35, coupling agent coating is completed with the help of the coupling agent delivery assembly 7, and the purpose of detecting the weld is completed with the help of the ultrasonic probe 20.

[0032] In this embodiment, the cleaning mechanism 6 includes a grinding plate 35, a second motor 33 and a slag removal frame 11. The second motor 33 and the air pump 36 are screwed to the surface of the top plate 10. The output end of the second motor 33 is plugged with a drive shaft 34. The grinding plate 35 is installed at the end of the drive shaft 34. The interior of the slag removal frame 11 is divided into a slag removal interlayer 13 and a guide interlayer 14. A partition 41 is provided between the slag removal interlayer 13 and the guide interlayer 14. A collection port 37 is provided on one side of the bottom of the slag removal interlayer 13. The collection port 37 is an arc-shaped structure as a whole. One end of the air pump 36 is connected to the interior of the slag removal interlayer 13 through a pipeline, and the air pump 36 is used to extract the residue collected at the bottom of the slag removal interlayer 13 upward. The bottom of the partition 41 is directly pressed against the weld to be tested. An elastic membrane 38 and a support plate 39 are attached to the inner wall of the guide interlayer 14. The elastic membrane 38 is arranged at the top of the support plate 39. The surface of the support plate 39 and the bottom of the elastic membrane 38 are both attached with conductive contacts 40. The entire support frame 5 is controlled by the first motor 8 at the top to move horizontally along the surface of the workpiece to be tested. During this movement, the weld area to be tested can be pre-polished to remove metal slag and protruding structures on the weld surface, thereby improving the accuracy of subsequent ultrasonic probe 20 detection of the structure. This process can also directly collect and discharge the residue produced by grinding, and can directly detect when a large degree of depression appears on the weld surface, further expanding the scope of detection of different problems arising from the weld area.

[0033] Specifically, after starting the second motor 33, the driving shaft 34 drives the grinding plate 35 at the bottom to rotate at a high speed, so that the weld area pressed by the grinding plate 35 can be directly ground, and the protrusions on the weld surface and the adhered metal residue parts can be removed, ensuring that the subsequent coating of the coupling agent is more uniform and effective. After grinding, the debris residue generated by grinding will be moved toward the inside of the slag removal interlayer 13 through the movement of the slag removal frame 11, and the debris residue will be blocked by the partition 41. After starting the air pump 36 at the top, the inside of the slag removal interlayer 13 can be collected. The collected residue is sucked out to complete the residue removal process. When a larger concave area appears on the weld, the partition 41 is pressed onto the area, causing the concave to connect the slag removal interlayer 13 and the guide interlayer 14 on both sides of the partition 41. Therefore, when the air pump 36 extracts the internal air of the slag removal interlayer 13, the air inside the guide interlayer 14 can be simultaneously pumped through the concave area, causing the middle-mounted diaphragm part to bulge downward, contacting the two conductive contacts 40, generating an electrical signal, and then judging the larger concave problem in the corresponding weld area inside the current slag removal frame 11.

[0034] In this embodiment, the coating mechanism 17 comprises a coating roller 21 and a baffle 25. The coating roller 21 has multiple through-holes 22 formed in its surface. The baffle 25 is integrally embedded within the coating roller 21. Support rings 42 are sleeved on both ends of the coating roller 21, the sides of which are fixed to the surface of the slag removal frame 11. A threaded post 23 is welded to the center of the baffle 25, and a bottom clamping plate 24 is integrally formed on the surface of the threaded post 23. Both ends of the coating roller 21 have threaded holes, through which the threaded post 23 passes. There are two threaded posts 23 and two baffles 25. The top of the coating roller 21 rests against the bottom of the couplant tank 16. A couplant delivery assembly 7 is mounted in the center of the support frame 5. The couplant delivery assembly 7 within this assembly automatically applies couplant to the surface of the workpiece being tested, depending on the speed and distance of the movement. This process eliminates the need for manual operation, resulting in more uniform and efficient coating and reduced complexity.

[0035] Specifically, when the entire coupling agent delivery assembly 7 is moved by the support frame 5, the coating roller 21 is pressed against the surface of the workpiece to be measured and rolled. At this time, the coupling agent injected inside can be partially overflowed downward through the through-hole 22 of the bottom layer through the rotation effect of the coating roller 21, thereby completing the purpose of coupling agent coating. By rotating the threaded column 23, the distance between the two baffles 25 can be changed, thereby controlling the flow range allowed by the coupling agent injected inside the coating roller 21, thereby changing the width range of the coupling agent coating on the surface of the workpiece to be measured. Through this structure, the coupling agent coating range can be adjusted according to the specific width of the weld to be measured.

[0036] In this embodiment, the coupling agent tank 16 is integrally formed at the bottom of the column 15. An inlet 26 is defined on the surface of the coupling agent tank 16. An arcuate groove 27 is integrally formed at the bottom of the inner wall of the tank 16. A docking hole 28 is defined at the bottom of the arcuate groove 27. Sealing posts 29 are inserted at both ends of the coupling agent tank 16. The ends of these sealing posts 29 are integrally formed with a top clamping plate 30. A linkage plate 31 is sleeved within the inner side of the top clamping plate 30. A collar 32 is integrally formed at the bottom of the linkage plate 31. This collar 32 is sleeved within the inner side of the bottom clamping plate 24. The sealing posts 29 are embedded within the arcuate groove 27 and serve to seal the docking hole 28. When controlling the coating mechanism 17 to apply the coupling agent, the actual coating range of the coupling agent can be adjusted according to the actual width of the weld to be measured, thereby improving the utilization rate of the coupling agent for welds of different widths. This process can also be synchronized with the width range of the coupling agent injected into the top coupling agent tank 16, ensuring that the coupling agent in the coupling agent tank 16 is efficiently transported to the coating mechanism 17 without causing a large amount of coupling agent to overflow outside the weld.

[0037] Specifically, when the threaded column 23 is rotated to drive the end baffle 25 to move, the inner ring 32 is also pulled by the bottom clamping plate 24 to perform linear motion, and then the sealing column 29 is pulled by the top clamping plate 30 to move inside the coupling agent tank 16. When the sealing column 29 moves along the inside of the arc groove 27, the docking holes 28 within different length ranges can be blocked. During the subsequent rotation of the coating roller 21, it can be ensured that the coupling agent inside the coupling agent tank 16 can only flow from the unblocked docking holes 28 in the middle area into the through holes 22 within the corresponding width range inside the coating roller 21, thereby ensuring that the coupling agent can only be applied within the regulated weld width range.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
