Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic flaw detection, and in particular to a handheld ultrasonic flaw detection device. Background Technology

[0002] An ultrasonic flaw detector is a portable industrial non-destructive testing instrument. It can quickly, conveniently, non-destructively, and accurately detect, locate, evaluate, and diagnose various internal defects (cracks, porosity, air holes, inclusions, etc.) in workpieces. It can be used in laboratories as well as in engineering sites and is widely used in industries such as boilers, pressure vessels, aerospace, aviation, power, petroleum, chemical, offshore oil, pipelines, military, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing, steel structures, railway transportation, nuclear power, and universities.

[0003] Existing ultrasonic flaw detection technologies, such as the prior art with application number CN201921938049.6, include a flaw detector body, a transverse buffer, a top buffer, a bottom buffer, a fixing member, a rectangular hole, a connecting rod, a first tension spring, a connecting groove, a fixing hole, and a triangular groove. By pulling the triangular rod, the triangular rod leaves the corresponding triangular groove. Under the tension of the first tension spring, the two transverse buffers move away from each other, releasing the flaw detector body. At the same time, the bottom buffer moves away from the flaw detector body, making it easy to remove the flaw detector body.

[0004] However, during long-duration inspection tasks, it can be tiring for staff to operate the flaw detector by hand. Current technology makes it inconvenient to place the flaw detector on the operator's waist, reducing convenience. Furthermore, current technology makes it difficult to mark the damaged areas, reducing practicality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a handheld ultrasonic flaw detection device that is easy to handle in two ways, improves practicality, and facilitates marking of flawed locations.

[0006] This utility model discloses a handheld ultrasonic flaw detection device, including a flaw detection mechanism, a marking mechanism, a carrying mechanism, a waist-mounted mechanism, a first fixing mechanism, and a capping mechanism. The marking mechanism, carrying mechanism, and waist-mounted mechanism are all mounted on the flaw detection mechanism. The first fixing mechanism and the capping mechanism are also mounted on the waist-mounted mechanism. Ultrasonic flaw detection is performed through the flaw detection mechanism. The marking mechanism facilitates marking the location of flaws. The carrying mechanism facilitates carrying the flaw detection mechanism by hand. The waist-mounted mechanism facilitates fixing the flaw detection mechanism to the operator's waist. The first fixing mechanism and the capping mechanism facilitate fixing both ends of the waist-mounted mechanism. The marking mechanism facilitates marking the location of flaws. The carrying mechanism facilitates carrying the flaw detection mechanism for short-term use by the operator. The waist-mounted mechanism facilitates fixing the flaw detection mechanism to the operator's waist for extended use. The first fixing mechanism and the capping mechanism facilitate fixing both ends of the waist-mounted mechanism, improving practicality and convenience.

[0007] Preferably, the flaw detection mechanism includes a flaw detector analyzer, a connecting line, a flaw detector handle, and a flaw detector head. One end of the connecting line is installed on the flaw detector analyzer, the flaw detector handle is installed on the other end of the connecting line, and the flaw detector head is installed on the flaw detector handle. By holding the flaw detector handle, the flaw detector head is used to perform ultrasonic flaw detection on the test piece, and then the data is transmitted to the flaw detector analyzer for analysis and processing via the connecting line.

[0008] Preferably, the marking mechanism includes a mounting plate, a rotating gear ring, a marking motor, a marking gear, a marking pen, a limiting plate, and a first spring. The mounting plate is mounted on the flaw detection handle, the rotating gear ring is rotatably mounted on the mounting plate, the marking motor is mounted on the flaw detection handle via a motor bracket, a marking gear is mounted on the output end of the marking motor, the marking gear meshes with the rotating gear ring, a placement plate is provided on the rotating gear ring, the marking pen is slidably mounted on the placement plate, the limiting plate is mounted on the top of the marking pen, and the first spring connects the limiting plate and the placement plate. When the flaw detection head detects a flaw, the flaw detection handle is brought close to the piece being inspected, and then the marking motor is turned on to drive the marking gear to rotate. Then, through the meshing relationship, the rotating gear ring is driven to rotate, which in turn drives the marking pen to rotate around the flaw detection handle. With the assistance of the elasticity of the first spring, the marking pen completes the marking of the flawed location.

[0009] Preferably, the carrying mechanism includes a handle, two second springs, and two limiting blocks. The flaw detector analyzer is provided with a storage slot. The two ends of the handle are slidably installed in the storage slot of the flaw detector analyzer. The second springs connect the inner wall of the storage slot to the handle. The limiting blocks are installed on the second springs. The flaw detector analyzer is provided with a limiting groove, and the limiting blocks are located in the limiting groove. When working for a short time, the handle can be pulled out and limited by the limiting blocks. The flaw detector analyzer can be carried by the handle. After use, the handle can be released, and the handle can be retracted into the storage slot of the flaw detector analyzer by the second springs.

[0010] Preferably, the waist-mounted mechanism includes a take-up and release shaft, a fixing belt, a clamping sleeve, and a clamping post. A mounting frame is provided on the outer wall of the flaw detector. The take-up and release shaft is rotatably mounted on the mounting frame via a spiral spring. One end of the fixing belt is mounted on the take-up and release shaft. The clamping sleeve is mounted on the outer wall of the flaw detector and has a notch. The clamping post is mounted on the other end of the fixing belt. When working for a long time, the fixing belt is pulled out from the take-up and release shaft, then wrapped around the operator's waist. The clamping post is then slid from the top of the clamping sleeve into the clamping sleeve, at which point the fixing belt passes through the notch of the clamping sleeve. The take-up and release shaft is then fixed by a first fixing mechanism, and the top of the clamping sleeve is sealed by a sealing mechanism to prevent the clamping post from sliding out of the clamping sleeve, thus improving practicality. When it is time to remove, the fixing belt is wound up by the elasticity of the spiral spring on the take-up and release shaft.

[0011] Preferably, the first fixing mechanism includes a fixing box, a sliding fixing block, and a threaded rod. The fixing box is mounted on the mounting bracket of the take-up and release shaft. The sliding fixing block is slidably mounted on the inner wall of the fixing box. The threaded rod is threadedly mounted on the side wall of the fixing box and rotatably mounted on the sliding fixing block. When working for a long time, the fixing strap is pulled out from the take-up and release shaft, then wrapped around the operator's waist. The locking pin is then slid from the top of the locking cylinder into the locking cylinder, at which point the fixing strap passes through the notch of the locking cylinder. Then, by rotating the threaded rod, the sliding fixing block is slid within the fixing box due to the threaded relationship, thereby fixing the take-up and release shaft. The top of the locking cylinder is sealed by a sealing mechanism to prevent the locking pin from sliding out of the locking cylinder, improving practicality. When it is time to remove, the fixing strap is wound up by the elasticity of the spiral spring on the take-up and release shaft.

[0012] Preferably, the sealing mechanism includes a sealing plate and a rotating shaft. The sealing plate is rotatably mounted on the top of the clamping cylinder via the rotating shaft. When working for an extended period, the fixing strap is pulled out from the take-up and release shaft, then wrapped around the operator's waist. The clamping pin is then slid from the top of the clamping cylinder into the clamping cylinder, at which point the fixing strap passes through the notch in the clamping cylinder. The threaded rod is then rotated to drive the sliding fixing block to slide within the fixing box, thereby fixing the take-up and release shaft. By rotating the sealing plate, the top of the clamping cylinder is sealed, preventing the clamping pin from sliding out of the clamping cylinder and improving practicality. When it is time to remove the clamping strap, the elasticity of the spiral spring on the take-up and release shaft is used to wind it up.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Ultrasonic flaw detection is performed by a flaw detection mechanism. The marking mechanism facilitates marking of flawed locations. The carrying mechanism allows for easy carrying of the flaw detection mechanism for short-term use by the operator.

Detailed Implementation

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] like Figures 1 to 5 As shown, a handheld ultrasonic flaw detection device includes a flaw detection mechanism 01, a marking mechanism 02, a carrying mechanism 03, a waist-mounted mechanism 04, a first fixing mechanism 05, and a capping mechanism 06. The marking mechanism 02 is mounted on the flaw detection mechanism 01, the carrying mechanism 03 is mounted on the flaw detection mechanism 01, the waist-mounted mechanism 04 is mounted on the flaw detection mechanism 01, the first fixing mechanism 05 is mounted on the waist-mounted mechanism 04, and the capping mechanism 06 is mounted on the waist-mounted mechanism 04.

[0023] Ultrasonic flaw detection is performed by flaw detection mechanism 01, marking mechanism 02 facilitates marking of flawed locations, hand-carrying mechanism 03 facilitates hand-carrying of flaw detection mechanism 01, waist-mounting mechanism 04 facilitates fixing flaw detection mechanism 01 to the operator's waist, and first fixing mechanism 05 and top-sealing mechanism 06 facilitate fixing both ends of waist-mounting mechanism 04.

[0024] The flaw detection mechanism 01 includes a flaw detector 11, a connecting line 12, a flaw detection handle 13, and a flaw detection head 14. One end of the connecting line 12 is installed on the flaw detector 11, the flaw detection handle 13 is installed on the other end of the connecting line 12, and the flaw detection head 14 is installed on the flaw detection handle 13.

[0025] The marking mechanism 02 includes a mounting plate 21, a rotating gear ring 22, a marking motor 23, a marking gear 24, a marking pen 25, a limiting plate 26, and a first spring 27. The mounting plate 21 is mounted on the flaw detection handle 13. The rotating gear ring 22 is rotatably mounted on the mounting plate 21. The marking motor 23 is mounted on the flaw detection handle 13 via a motor bracket. The marking gear 24 is mounted on the output end of the marking motor 23. The marking gear 24 meshes with the rotating gear ring 22. A placement plate is provided on the rotating gear ring 22. The marking pen 25 is slidably mounted on the placement plate. The limiting plate 26 is mounted on the top of the marking pen 25. The first spring 27 connects the limiting plate 26 and the placement plate.

[0026] The carrying mechanism 03 includes a handle 31, two second springs 32 and two limiting blocks 33. The flaw detector 11 is provided with a storage groove. The two ends of the handle 31 are slidably installed in the storage groove of the flaw detector 11. The second springs 32 are connected to the inner wall of the storage groove and the handle 31. The limiting blocks 33 are installed on the second springs 32. The flaw detector 11 is provided with a limiting groove. The limiting blocks 33 are located in the limiting groove.

[0027] Holding the flaw detection handle 13, the flaw detection head 14 performs ultrasonic flaw detection on the test piece. The data is then transmitted to the flaw detector 11 for analysis via the connecting cable 12. When the flaw detection head 14 detects a flaw, the flaw detection handle 13 is brought close to the test piece. The marking motor 23 is then turned on, which drives the marking gear 24 to rotate. This, in turn, drives the rotating gear ring 22 to rotate, which in turn drives the marking pen 25 to rotate around the flaw detection handle 13. With the elastic assistance of the first spring 27, the marking pen 25 marks the location of the flaw. When working for a short time, the carrying handle 31 can be pulled out and limited by the limiting block 33. The flaw detector 11 can be carried by the carrying handle 31. After use, the carrying handle 31 can be released and retracted into the storage slot of the flaw detector 11 by the second spring 32.

[0028] The waist-mounted mechanism 04 includes a take-up and release shaft 41, a fixing belt 42, a clamping sleeve 43, and a clamping post 44. A mounting frame is provided on the outer wall of the flaw detector 11. The take-up and release shaft 41 is rotatably mounted on the mounting frame by a spiral spring. One end of the fixing belt 42 is mounted on the take-up and release shaft 41. The clamping sleeve 43 is mounted on the outer wall of the flaw detector 11 and has a notch. The clamping post 44 is mounted on the other end of the fixing belt 42.

[0029] The first fixing mechanism 05 includes a fixing box 51, a sliding fixing block 52, and a threaded rod 53. The fixing box 51 is mounted on the mounting bracket on the take-up and put-out shaft 41. The sliding fixing block 52 is slidably mounted on the inner wall of the fixing box 51. The threaded rod 53 is threadedly mounted on the side wall of the fixing box 51 and is rotatably mounted on the sliding fixing block 52.

[0030] The capping mechanism 06 includes a capping plate 61 and a rotating shaft 62. The capping plate 61 is rotatably mounted on the top of the clamping cylinder 43 via the rotating shaft 62.

[0031] When working for an extended period, pull the retaining strap 42 out of the take-up and release shaft 41, then wrap the retaining strap 42 around the operator's waist. Next, slide the locking pin 44 from the top of the locking cylinder 43 into the cylinder 43, at which point the retaining strap 42 passes through the notch of the cylinder 43. Then, rotate the threaded rod 53, and due to the thread, drive the sliding fixing block 52 to slide within the fixing box 51, thereby fixing the take-up and release shaft 41. By rotating the sealing plate 61, the sealing plate 61 seals the top of the cylinder 43, preventing the locking pin 44 from sliding out of the cylinder 43, thus improving practicality. When it is time to remove, rotate the sealing plate 61 to remove the locking pin 44 from the cylinder 43, allowing one end of the retaining strap 42 to be pulled out from the notch of the cylinder 43. Then, the elasticity of the spiral spring on the take-up and release shaft 41 winds up the retaining strap 42.

[0032] like Figures 1 to 5As shown, this utility model discloses a handheld ultrasonic flaw detection device. During operation, the user holds the flaw detection handle 13 and uses the flaw detection head 14 to perform ultrasonic flaw detection on the test piece. The data is then transmitted to the flaw detector 11 via the connecting cable 12 for analysis. When the flaw detection head 14 detects a flaw, the user brings the flaw detection handle 13 closer to the test piece. The marking motor 23 then drives the marking gear 24 to rotate, which in turn drives the rotating gear ring 22 to rotate. This, in turn, causes the marking pen 25 to rotate around the flaw detection handle 13. With the assistance of the first spring 27, the marking pen 25 marks the location of the flaw. For short-term operation, the carrying handle 31 can be pulled out and limited by the limiting block 33. The user can then carry the flaw detector 11 using the carrying handle 31. After use, the handle is released. The carrying handle 31 can be retracted into the storage slot of the flaw detector analyzer 11 by the second spring 32. When working for a long time, the fixing strap 42 is pulled out from the take-up and release shaft 41, and then the fixing strap 42 is wrapped around the operator's waist. Then the locking pin 44 is slid from the top of the locking cylinder 43 into the locking cylinder 43. At this time, the fixing strap 42 just passes through the notch of the locking cylinder 43. Then, by rotating the threaded rod 53, the sliding fixing block 52 is driven to slide in the fixing box 51 due to the thread relationship. The take-up and release shaft 41 is fixed by the sliding fixing block 52. By rotating the sealing plate 61, the sealing plate 61 seals the top of the locking cylinder 43 to prevent the locking pin 44 from sliding out of the locking cylinder 43, thus improving practicality. When it is time to remove, the fixing strap 42 is wound up by the elasticity of the spiral spring on the take-up and release shaft 41.

[0033] The flaw detector analyzer 11, flaw detector head 14 and marking motor 23 of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0034] The main function achieved by this utility model is to facilitate the handling of the flaw detector analyzer 11 in two ways during ultrasonic flaw detection, thereby improving its practicality and making it easier to mark the damaged locations.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
