Description

Technical Field

[0001] The utility model relates to the technical field related to ultrasonic flaw detection equipment, in particular to a handheld ultrasonic flaw detection equipment used for non-destructive testing. Background Art

[0002] Ultrasonic flaw detectors are portable industrial non-destructive flaw detection instruments that can quickly, conveniently, non-destructively, and accurately detect, locate, evaluate, and diagnose a variety of internal defects in workpieces. They can be used in laboratories and on-site, and are widely used in industries such as boilers, metallurgy, metal processing, steel structures, railway transportation, nuclear power, and universities. There are many types of handheld ultrasonic flaw detection equipment available, such as:

[0003] Publication No. CN218412378U discloses a handheld ultrasonic flaw detector with drop prevention. The ultrasonic flaw detector comprises a flaw detector body, connecting cables, an ultrasonic probe, a buffer protection assembly, a connecting strap, a clamping hole, a fixing assembly, and a through-plate. This provides drop prevention and buffer protection. This solves the problem that, when inspecting large machinery, handheld ultrasonic flaw detectors are often secured to the hand using straps mounted on the side walls of the handheld flaw detector, requiring the hand to grasp the handheld ultrasonic flaw detector body. This simple securing method makes it easy for the handheld ultrasonic flaw detector to slip and fall to the ground if bumped. If it falls and collides with the hard surface, the ultrasonic flaw detector can be damaged, rendering the internal components inoperable. The ultrasonic flaw detector is protected from damage by mounting mechanisms at its corners. However, when the ultrasonic flaw detector is handheld, the springs and components of the mechanism can cause scratches between the user's hand and the mechanism, making it inconvenient to use.

[0004] Therefore, we proposed that handheld ultrasonic flaw detection equipment for non-destructive testing can solve the above problems well. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0031] Example 1: In order to solve the problem that the ultrasonic flaw detector on the market is installed with a mechanism at the corner of the ultrasonic flaw detector to prevent it from being broken when in use, but when the ultrasonic flaw detector is used by hand, the spring and the components of the mechanism may cause scratches on the user's hand. Figure 1 -Attached Figure 5, including a protective box 1, a group of ultrasonic flaw detection components 4 are arranged inside the protective box 1, a group of connecting wires 5 are connected to the connecting end position of the ultrasonic flaw detection component 4, and the tail end position of the connecting wire 5 is connected to the flaw detection head 6; it also includes: a group of driving motors 10 are fixed at the left side position inside the protective box 1, and the output end position of the driving motor 10 is connected to the left end of the bidirectional threaded rod 11, and the outer side position of the bidirectional threaded rod 11 is threadedly connected to the outer side of the connecting sleeve 12, and the top of the connecting sleeve 12 is rotatably connected to the bottom end of the support rod 13, and the top position of the support rod 13 is rotated to the bottom position of the ultrasonic flaw detection component 4, and a group of fixed connecting parts 14 are fixed to the left bottom of the ultrasonic flaw detection component 4 and the left side position of the protective box 1. The outer sides of the two groups of fixed connecting parts 14 are rotatably connected to the upper and lower ends of the left side of the supporting connecting component 15, and the upper and lower ends of the right side of the supporting connecting component 15 are rotatably connected to the outer sides of the two groups of sliding connecting parts 16, and the outer side of a group of sliding connecting parts 16 is slidably set in the guide groove 17 opened at the bottom of the ultrasonic flaw detection component 4. A cover plate 2 is hingedly mounted on the top rear side of the protective case 1. A handle strap 3 is secured to the top of the cover plate 2 for easy portability. A support connection assembly 15 comprises two sets of adjacent rods hingedly connected. A sliding connection 16, located on the lower right side of the support connection assembly 15, slides within a groove within the protective case 1. In order to use the device for non-destructive testing, the staff first carries the protective box 1 and the cover 2 with the hand strap 3 for use. After moving to the designated position, the cover 2 is opened and the drive motor 10 is started so that the output end of the drive motor 10 drives the bidirectional threaded rod 11 to rotate. At this time, the connecting sleeves 12 threadedly connected at both ends of the outer side of the bidirectional threaded rod 11 drive the support rod 13 to adjust its position. At this time, the support rod 13 is rotated and connected to the bottom position of the ultrasonic flaw detection component 4, so that the ultrasonic flaw detection component 4 can be adjusted in height. At this time, when the ultrasonic flaw detection component 4 moves, since the guide groove 17 provided at the bottom of the ultrasonic flaw detection component 4 is provided with a sliding connection 16, the sliding connection 16 can slide inside the guide groove 17 of the slide groove 9. The sliding connection 16 will drive the rods of the support connection component 15 to rotate relative to each other. In addition, the left end of the support connection component 15 rotates outside the fixed connection 14. At this time, the ultrasonic flaw detection component 4 can be stably adjusted in height, which facilitates the extension of the ultrasonic flaw detection component 4 and avoids scratches caused by contact with other components.

[0032] Example 2: In order to avoid excessive dust from affecting the nondestructive testing of the flaw detection head 6, please refer to the attached Figure 1 and attached Figure 5 -Attached Figure 7A rotating rod 18 is fixed to the right end of the bidirectional threaded rod 11. An eccentric weight 19 is fixed to the outside of the rotating rod 18. The outside of the eccentric weight 19 fits against the bottom outside of the airbag 20. An air supply pipe 21 is connected to the left outside of the airbag 20. The tail end of the air supply pipe 21 is connected to one side of a pressure jet head 22. The airbag 20 is made of elastic rubber. An outlet check valve is installed at one end of the airbag 20 connected to the air supply pipe 21, and an inlet check valve is installed on the outside of the airbag 20. The eccentric weight 19 is located inside the bottom end of the placement block 7, and the outside of the pressure jet head 22 corresponds to the outside position of the flaw detection head 6. By driving the rotating rod 18 to rotate through the bidirectional threaded rod 11, the rotating rod 18 can drive the eccentric block 19 to rotate inside the bottom end of the placement block 7, so that the outer side of the eccentric block 19 squeezes the outer side of the airbag 20, so that the airbag 20 is transported to the inside of the air pipe 21 through the air outlet one-way valve, and the gas can be sprayed through the pressure jet head 22 to clean the outer side of the flaw detection head 6.

[0033] Example 3: In order to facilitate the removal of the flaw detection head 6, please refer to the attached Figure 1 and attached Figure 2 A hole is provided on the right side of the protective box 1 to facilitate the extension of the flaw detection head 6, and a set of closing covers 8 are fitted on the outside of the hole. Both sides of the closing cover 8 are slidably set in the slide 9 opened on the side of the protective box 1. In addition, a set of magnetic blocks are fixed at the upper and lower ends of the slide 9, and magnets with opposite magnetic forces to the magnetic blocks in the slide 9 are provided at the upper and lower ends of the closing cover 8. By sliding the closing cover 8, the closing cover 8 can be adjusted up and down inside the slide 9. Since magnets are provided on one side of the closing cover 8 and the slide 9, the two sets of opposite magnets can be used for adsorption processing, which makes it convenient to take out and put in the flaw detection head 6 and prevents dust from entering the interior of the protective box 1 and affecting the ultrasonic flaw detection component 4.
