[0002] Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument, which can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece. It can be used in laboratories as well as on-site projects. It is widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical industry, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing industry, steel structure, railway transportation, nuclear power, colleges and universities and other industries.

[0003] After being used for a long time, the ultrasonic flaw detector needs to be inspected and maintained irregularly, which requires the use of a detection and positioning device to perform fixed inspection on it. However, the detection and positioning device in the existing technical solution has a relatively simple structure and can only be used for fixed inspection of a single model of ultrasonic flaw detector, and cannot be used for fixed inspection of ultrasonic flaw detectors of different models. This leads to limitations in the use of the detection and positioning device. Utility Model Content

[0004] The embodiment of the present application provides an ultrasonic flaw detector maintenance detection and positioning device, which solves the problem that the detection and positioning device in the prior art solution can only be used for fixed detection of a single model of ultrasonic flaw detector due to its relatively simple structure, and cannot be used for fixed detection of ultrasonic flaw detectors of different models, which leads to the technical problem that the detection and positioning device is subject to limitations when in use.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A maintenance and inspection positioning device for an ultrasonic flaw detector comprises a base, a support plate hinged on the base, a support block for supporting the ultrasonic flaw detector, a positioning mechanism for fixing the ultrasonic flaw detector, a moving assembly for driving the positioning mechanism to move, and an adjusting device for adjusting the angle of the support plate; the base is provided with a plurality of groups of slots arranged in a linear array; the adjusting device is arranged on the support plate, and the adjusting device is plugged into one of the groups of slots; the support block and the moving assembly are both arranged on the support plate; and two groups of positioning mechanisms arranged symmetrically are arranged on the moving end of the moving assembly;

[0007] The moving assembly includes a moving plate, a slider sliding on the supporting plate, a first threaded rod for driving the slider to move, and a bearing seat for supporting the first threaded rod; two groups of symmetrically placed sliders are threadedly connected to the first threaded rod; the moving plate is provided on both groups of sliders; the positioning mechanism is provided on both groups of moving plates; the bearing seats are provided at both ends of the first threaded rod; and the two groups of bearing seats are provided on the supporting plate.

[0008] A further technical solution is: the positioning mechanism includes a stopper for abutting against the ultrasonic flaw detector and a second threaded rod threadedly connected to the movable plate; the stopper is arranged at one end of the second threaded rod.

[0009] A further technical solution is: the adjusting device comprises a pin seat and a support rod swingably connected to the pin seat; the pin seat is arranged on the support plate; and the support rod is inserted into one group of the slots.

[0010] A further technical solution is: the moving assembly also includes a threaded handle; the threaded handle is arranged at one end of the first threaded rod.

[0011] A further technical solution is: the positioning mechanism also includes a rubber pad and a first bending handle for driving the second threaded rod to rotate; the rubber pad is arranged on the stopper; and the first bending handle is arranged at the other end of the second threaded rod.

[0012] A further technical solution is: the adjusting device also includes a second bending handle; the second bending handle is arranged on the supporting rod.

[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0014] 1. Due to the use of the base, support plate, support block, positioning mechanism, moving assembly and adjustment device, when the ultrasonic flaw detector needs to be inspected and repaired, the staff first places the ultrasonic flaw detector on the support plate and makes the bottom of the ultrasonic flaw detector rest on the support block. Then the staff starts working through the moving assembly. The staff rotates the first threaded rod in the moving assembly so that the two sets of sliders simultaneously carry the corresponding moving plates to slide close to the ultrasonic flaw detector. When the two sets of moving plates slide a certain distance close to the ultrasonic flaw detector, the positioning mechanisms on the two sets of moving plates are rotated in sequence so that the two sets of positioning mechanisms simultaneously rest on the ultrasonic flaw detector. At this time, the ultrasonic flaw detector placed on the support plate can be effectively fixed. Then the staff can inspect and repair the ultrasonic flaw detector. The whole operation process is simple and reliable, and it is convenient for the staff to operate. Since the spacing between the two sets of positioning mechanisms can be adjusted by rotating the first threaded rod in the moving assembly, different types of ultrasonic flaw detectors can be fixed between the two sets of positioning mechanisms, thereby greatly improving the practicality of the ultrasonic flaw detector maintenance and inspection positioning device. When the angle of the support plate needs to be adjusted, the staff can take out the adjustment device from one group of slots and insert it into another group of slots. At this time, the angle of the support plate can be adjusted, which makes it more convenient for the staff to operate the ultrasonic flaw detector fixed on the support plate.

[0015] 2. Due to the setting of the stopper and the second threaded rod, when the ultrasonic flaw detector is fixed by two sets of positioning mechanisms, the staff will turn the second threaded rods in the two sets of positioning mechanisms in turn, so that the two sets of second threaded rods respectively drive the corresponding stoppers to move closer to the ultrasonic flaw detector. When the two sets of stoppers are against the ultrasonic flaw detector at the same time, the ultrasonic flaw detector can be effectively fixed.

[0016] 3. Due to the setting of the pin shaft seat and the support rod, since the support rod is swingably connected to the pin shaft in the pin shaft seat, and the pin shaft seat is fixedly connected to the bottom of the support plate, when the staff takes the support rod out of one set of slots and inserts it into another set of slots, the support rod swings around the pin shaft in the pin shaft seat at a certain angle, and the angle of the support plate can be adjusted at this time.

[0017] 4. Due to the setting of the threaded handle, the staff can drive the first threaded rod to rotate by rotating the threaded handle, which makes it more convenient for the staff to operate.

[0018] 5. Due to the use of the rubber pad, when the block is against the ultrasonic detector, the rubber pad on the block will contact the ultrasonic flaw detector, thereby providing a certain degree of protection for the ultrasonic flaw detector. Due to the use of the first bending handle, the staff can drive the second threaded rod to rotate by rotating the first bending handle, thereby making it more convenient for the staff to operate.

[0019] 6. Due to the provision of the second bending handle, the second bending handle can facilitate the staff to lift the support rod, thereby making it more convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The embodiment of the present application provides an ultrasonic flaw detector maintenance detection and positioning device, which solves the problem that the detection and positioning device in the prior art solution can only be used for fixed detection of a single model of ultrasonic flaw detector due to its relatively simple structure, and cannot be used for fixed detection of ultrasonic flaw detectors of different models, which leads to the technical problem that the detection and positioning device is subject to limitations when in use.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] A maintenance, detection and positioning device for an ultrasonic flaw detector, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, a support plate 2 hinged on the base 1, a support block 3 for supporting an ultrasonic flaw detector, a positioning mechanism 4 for fixing the ultrasonic flaw detector, a moving assembly 5 for driving the positioning mechanism 4 to move, and an adjusting device 6 for adjusting the angle of the support plate 2. The base 1 is provided with a plurality of groups of slots 11 arranged in a linear array. The adjusting device 6 is arranged on the support plate 2, and the adjusting device 6 is inserted into one of the groups of slots 11. The support block 3 and the moving assembly 5 are both arranged on the support plate 2. Two groups of positioning mechanisms 4 arranged symmetrically are arranged on the moving end of the moving assembly 5.

[0030] The moving assembly 5 includes a moving plate 51, a slider 52 sliding on the support plate 2, a first threaded rod 53 for driving the slider 52 to move, and a bearing seat 54 for supporting the first threaded rod 53. Two groups of sliders 52 symmetrically placed are threadedly connected to the first threaded rod 53. The two groups of sliders 52 are both provided with a moving plate 51. The two groups of moving plates 51 are both provided with a positioning mechanism 4. The first threaded rod 53 is provided with a bearing seat 54 at both ends. The two groups of bearing seats 54 are both provided on the support plate 2.

[0031] A pin is provided at the front end of the base 1, and the support plate 2 is swingably connected to the pin provided at the front end of the base 1. Three groups of slots 11 arranged in a linear array are provided at the top of the base 1. The adjusting device 6 is fixedly connected to the bottom of the support plate 2, and the adjusting device 6 is detachably inserted into one of the slots 11. The support block 3 and the moving component 5 are both fixedly connected to the top of the support plate 2. Two groups of symmetrically placed positioning mechanisms 4 are fixedly connected to the moving end of the moving component 5. The two groups of sliders 52 are both fixedly connected to the moving plates 51. The two groups of moving plates 51 are both fixedly connected to the positioning mechanisms 4. Bearing seats 54 are provided at both ends of the first threaded rod 53, and the two ends of the first threaded rod 53 are respectively fixedly connected to the inner rings of the bearings in the bearing seats 54. The two groups of bearing seats 54 are both fixedly connected to the top of the support plate 2. Since the two groups of sliders 52 are both threadedly connected to the first threaded rod 53, and the two groups of sliders 52 slide on the support plate 2, when the first threaded rod 53 is rotated, the two groups of sliders 52 can slide closer or farther along the surface of the support plate 2 at the same time.

[0032] Due to the arrangement of the base 1, the support plate 2, the support block 3, the positioning mechanism 4, the moving assembly 5 and the adjusting device 6, when the ultrasonic flaw detector needs to be inspected and repaired, the staff first places the ultrasonic flaw detector on the support plate 2 and makes the bottom end of the ultrasonic flaw detector rest on the support block 3, and then the staff starts working through the moving assembly 5. The staff rotates the first threaded rod 53 in the moving assembly 5 so that the two groups of sliders 52 simultaneously carry the corresponding moving plates 51 to slide close to the ultrasonic flaw detector. When the two groups of moving plates 51 slide close to the ultrasonic flaw detector for a certain distance, the positioning mechanisms 4 on the two groups of moving plates 51 are rotated in turn so that the two groups of positioning mechanisms 4 simultaneously rest on the ultrasonic flaw detector. At this time, the ultrasonic flaw detector placed on the support plate 2 can be effectively fixed, and then the staff can inspect and repair the ultrasonic flaw detector. The whole operation process is simple and reliable, and is convenient for the staff to operate. Since the spacing between the two sets of positioning mechanisms 4 can be adjusted by rotating the first threaded rod 53 in the moving assembly 5, different types of ultrasonic flaw detectors can be fixed between the two sets of positioning mechanisms 4, thereby greatly improving the practicality of the ultrasonic flaw detector maintenance and inspection positioning device. When it is necessary to adjust the angle of the support plate 2, the staff can remove the adjustment device 6 from one set of slots 11 and insert it into the other set of slots 11, so that the angle of the support plate 2 can be adjusted, which makes it more convenient for the staff to operate the ultrasonic flaw detector fixed on the support plate 2.

[0033] like Figure 4 As shown, the positioning mechanism 4 includes a stopper 41 for abutting against the ultrasonic flaw detector and a second threaded rod 42 threadedly connected to the moving plate 51. The stopper 41 is arranged at one end of the second threaded rod 42.

[0034] The stopper 41 is fixedly connected to one end of the second threaded rod 42 .

[0035] Due to the arrangement of the stopper 41 and the second threaded rod 42, when the ultrasonic flaw detector is fixed by the two sets of positioning mechanisms 4, the staff will rotate the second threaded rods 42 in the two sets of positioning mechanisms 4 in turn, so that the two sets of second threaded rods 42 respectively drive the corresponding stopper 41 to move closer to the ultrasonic flaw detector. When the two sets of stoppers 41 are against the ultrasonic flaw detector at the same time, the ultrasonic flaw detector can be effectively fixed.

[0036] like Figure 5 As shown, the adjusting device 6 includes a pin seat 61 and a support rod 62 swingably connected to the pin seat 61. The pin seat 61 is arranged on the support plate 2. The support rod 62 is inserted into one of the groups of slots 11.

[0037] One end of the support rod 62 is swingably connected to the pin in the pin seat 61. The pin seat 61 is fixedly connected to the bottom of the support plate 2. The support rod 62 is detachably plugged into one of the groups of slots 11.

[0038] Due to the arrangement of the pin shaft seat 61 and the support rod 62, since the support rod 62 is swingably connected to the pin shaft in the pin shaft seat 61, and the pin shaft seat 61 is fixedly connected to the bottom of the support plate 2, when the staff takes out the support rod 62 from one group of slots 11 and inserts it into another group of slots 11, the support rod 62 swings around the pin shaft in the pin shaft seat 61 by a certain angle, and the angle of the support plate 2 can be adjusted at this time.

[0039] like Figure 3 As shown, the moving assembly 5 further includes a threaded handle 55 . The threaded handle 55 is arranged at one end of the first threaded rod 53 .

[0040] The threaded handle 55 is fixedly connected to one end of the first threaded rod 53 .

[0041] Due to the provision of the threaded handle 55 , the staff can drive the first threaded rod 53 to rotate together by rotating the threaded handle 55 , thereby making the operation more convenient for the staff.

[0042] like Figure 4 As shown, the positioning mechanism 4 further includes a rubber pad 43 and a first bending handle 44 for driving the second threaded rod 42 to rotate. The rubber pad 43 is arranged on the stopper 41. The first bending handle 44 is arranged at the other end of the second threaded rod 42.

[0043] The rubber pad 43 is fixedly connected to the stopper 41. The first bending handle 44 is fixedly connected to the other end of the second threaded rod 42.

[0044] Due to the use of the rubber pad 43, when the stopper 41 abuts against the ultrasonic detector, the rubber pad 43 on the stopper 41 will contact the ultrasonic flaw detector, thereby providing a certain degree of protection for the ultrasonic flaw detector. Due to the use of the first bending handle 44, the staff can drive the second threaded rod 42 to rotate together by rotating the first bending handle 44, thereby making it more convenient for the staff to operate.

[0045] like Figure 5 As shown, the adjusting device 6 further includes a second bending handle 63. The second bending handle 63 is arranged on the supporting rod 62.

[0046] The second bending handle 63 is fixedly connected to the support rod 62 .

[0047] Due to the provision of the second bending handle 63 , the second bending handle 63 can facilitate the staff to lift the support rod 62 , thereby making it more convenient for the staff to operate.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
