Description

Technical Field

[0001] This utility model relates to the field of acoustic imaging detection, and specifically to an acoustic imaging detection device. Background Technology

[0002] The application of sound waves in flaw detection of target objects is becoming increasingly common. Ultrasonic waves propagate through various media, with longitudinal waves, transverse waves, surface waves, and plate waves being the most frequently used in inspection. Longitudinal waves can detect inclusions, cracks, shrinkage, white spots, or delamination in metal ingots, billets, medium-thick plates, large forgings, and relatively simple-shaped parts. Transverse waves can detect circumferential and axial cracks, scratches, porosity, slag inclusions, cracks, and incomplete penetration in pipes. Surface waves can detect surface defects on simple-shaped castings. Plate waves can detect defects in thin plates. Current acoustic imaging inspection instruments typically require manual handheld operation, making them difficult to use at high altitudes or inaccessible locations. The detection range is limited, and the fixed installation angle of the display module on these instruments hinders observation during inspection, presenting several limitations.

[0003] In the prior art, patent publication number CN218470627U discloses an acoustic imaging detector, including an electric telescopic rod. One end of the electric telescopic rod has a handle with a control switch for controlling the rod. The other end of the rod has a probe head containing a sound wave acquisition module and an image acquisition module. The probe head also includes a processor electrically connected to both the sound wave acquisition module and the image acquisition module, and a display module electrically connected to the processor, which is mounted on the handle. Addressing the technical problems of limited detection range and numerous limitations in existing acoustic imaging detectors, this invention provides an acoustic imaging detector that improves the detection range and overcomes these limitations.

[0004] The above technical solution solves the problems mentioned in the background art. However, when it is necessary to detect the upper surface of the component to be detected or when the detection component is blocked by a protruding object at a high place, the above technical solution using a straight rod cannot extend the probe to the part that needs to be detected.

[0005] Therefore, an acoustic imaging detection instrument is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an acoustic imaging detection device that solves the problem of how to make the acoustic imaging detection device more adaptable.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides an acoustic imaging detection device, including an outer sleeve and an inner sleeve inserted together. The outer sleeve has a first inner hole, and the inner sleeve is slidably inserted into the first inner hole. A rotating sleeve is embedded in the inner sleeve, and the rotating sleeve has a second inner hole. An adjusting rod is slidably fitted in the second inner hole. The rotation of the rotating sleeve and the adjusting rod around an axis is restricted. A connecting shaft is provided at the front end of the rotating sleeve, and the connecting shaft extends forward out of the inner sleeve. An end face gear that can rotate in a radial plane is provided at the front end of the connecting shaft. A probe head is oscillatingly connected to the front end of the inner sleeve. A deflection gear that can rotate in an axial plane is provided on the probe head, and the end face gear meshes with the deflection gear.

[0009] Preferably, the probe is connected to a rotating rod, which is oscillatingly connected to the front end of the inner sleeve.

[0010] Preferably, the rotation between the rotating sleeve and the adjusting rod about an axis is restricted by the fact that the cross-section of the second inner hole in the rotating sleeve is polygonal and the cross-section of the adjusting rod is a polygon that matches the second inner hole.

[0011] Preferably, the outer sleeve is provided with a locking bolt, which is threaded into the wall of the outer sleeve, and the inner end of the locking bolt extends into the first inner hole and abuts against the outer surface of the inner sleeve.

[0012] Preferably, a portal frame is provided at the front end of the inner sleeve, and the probe is connected to a rotating rod, which is rotatably connected to the portal frame.

[0013] Preferably, the rear end of the outer sleeve is provided with a rotating head that can rotate around an axis, and the rotating head is connected to the adjusting rod.

[0014] Preferably, a display module is rotatably mounted on the outer tube. The display module has a retracted state and an open state. The outer tube is provided with a first suction block and a second suction block. When the display module is in the retracted state, it is attracted to the first suction block. When the display module is in the open state, it is attracted to the second suction block. The device also includes a processor. The signal receiving end of the processor is connected to the probe head, and the signal output end of the processor is connected to the display module.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figure 1The acoustic imaging detection device shown mainly includes an outer sleeve 1, an inner sleeve 2, and a probe head 6 connected to the front end of the inner sleeve 2. The inner sleeve 2 can move back and forth within the outer sleeve 1 (defined). Figure 1 (The upper middle section is the front, the lower section is the back, and so on). The probe head 6 is swayable. The probe head 6 contains an acoustic wave acquisition module and an image acquisition module (not shown in the figure). It also includes a processor (not shown in the figure), whose signal receiving end is connected to the probe head 6, specifically to the acoustic wave acquisition module and the image acquisition module, and whose signal output end is connected to the display module 13. The processor can be housed within the gripping part 102 of the outer sleeve 1.

[0028] The connection method of the acoustic wave acquisition module, image acquisition module, processor and display module 13 can be wired or wireless. For the specific working principle, please refer to the acoustic imaging device disclosed in application number CN202022902657.0. The prior art will not be described in detail. In this patent, the probe part and the display module are electrically connected by an external wire.

[0029] The outer sleeve 1 and the inner sleeve 2 are inserted together. The outer sleeve 1 has a first inner hole 101, which is axial (defined as the front-to-back direction, i.e.) Figure 1 The inner sleeve 2 extends in the vertical direction (defined radially as the direction perpendicular to the axial direction). It is inserted into the first inner hole 101.

[0030] A portal frame 10 is mounted on the upper end of the inner sleeve 2. A swingable rotating rod 11 is mounted on the portal frame 10, and the distal end of the rotating rod 11 is connected to the probe head 6. The axis of rotation for swinging is radial. After the probe head 6 and the rotating rod 11 swing 90°, as... Figure 3 As shown. The gantry frame 10 is a preferred configuration, as long as the rotating rod 11 is swayably positioned at the front end of the inner sleeve 2. The rotating rod 11 is also a preferred configuration, which can increase the swing range of the probe head 6.

[0031] like Figure 2 The oscillation of the rotating rod 11 is achieved by the engagement between the deflecting gear 8 and the end face gear 7. The deflecting gear 8 and the end face gear 7 mesh with each other. The deflecting gear 8 is located near the end of the rotating rod 11 and can rotate axially with the rotating rod 11. The end face gear 7 is connected to the front end of the connecting shaft 5 and can rotate radially with the connecting shaft 5. The rotation of the end face gear 7 is driven by the connecting shaft 5. As the end face gear 7 rotates, it drives the deflecting gear 8 to rotate, thereby driving the probe head 6 to oscillate.

[0032] The deflecting gear 8 is disc-shaped, with first meshing teeth 81 on its outer periphery. The end face gear 7 includes a base plate 71 and a ring of toothed seats 72 extending from the edge of the base plate toward the deflecting gear 8. The end face of the toothed seats 72 is provided with second meshing teeth 73. The second meshing teeth 73 mesh with the first meshing teeth 81. When the end face gear 7 is driven to rotate by the connecting shaft 5, the deflecting gear 8 is driven to rotate, causing the rotating rod 11 to swing.

[0033] In other embodiments, the deflection gear 8 and the end face gear 7 may also be bevel gears.

[0034] An end-face gear 7 is connected to the front end of a connecting shaft 5, and a rotating sleeve 3 is connected to the rear end of the connecting shaft 5. The rotating sleeve 3 is rotatably disposed within the inner sleeve 2. Furthermore, the rotating sleeve 3 can move with the back-and-forth movement of the inner sleeve 2. The end-face dimension of the connection point between the rotating sleeve 3 and the connecting shaft 5 is larger than the cross-sectional dimension of the hole containing the connecting shaft 5, which prevents the rotating sleeve 3 from disengaging forward from the inner sleeve 2. The end-face dimension of the connection point between the end-face gear 7 and the connecting shaft 5 is larger than the cross-sectional dimension of the hole containing the connecting shaft, which prevents the rotating sleeve 3 from moving backward relative to the inner sleeve 2. Therefore, the rotating sleeve 3 and the inner sleeve 2 can move forward or backward together.

[0035] The rotating sleeve 3 has a second inner hole 301. The cross-section of the second inner hole 301 ( Figure 1 The horizontal cross-section of the adjusting rod 4 is polygonal. An adjusting rod 4 is inserted into the second inner hole 301. The cross-section of the adjusting rod 4 is also polygonal, matching the polygonal cross-section of the second inner hole 301. The rotation of the adjusting rod 4 and the rotating sleeve 3 around the axis is restricted, so that rotating the adjusting rod 4 can drive the rotating sleeve 3 to rotate.

[0036] The anti-rotation between the adjusting rod 4 and the rotating sleeve 3 can also be achieved in other ways, such as by setting a pin on the outer circumference of the adjusting rod 4 and setting an axially extending slide groove on the inner wall of the rotating sleeve 3, with the pin inserted into the slide groove.

[0037] A screw head 12 is provided at the lower end of the adjusting rod 4. The screw head 12 protrudes from the lower end of the outer sleeve 1, making it easy to turn by hand.

[0038] The lower end of the outer tube 1 is also provided with a grip part 102 with an increased diameter, which makes it easier for people to hold.

[0039] When a person holds the grip part 102, the other hand can be used to pull the inner sleeve 2 forward, causing the inner sleeve 2 to extend forward. After adjusting the extension length, the inner sleeve 2 is locked by the locking bolt 9. The locking bolt 9 is threaded into the wall of the outer sleeve 1, and the inner end of the locking bolt 9 extends into the first inner hole 101 and abuts against the outer surface of the inner sleeve 2 to achieve a locking effect.

[0040] The main function of the locking bolt 9 is to prevent axial sliding between the outer sleeve 1 and the inner sleeve 2. Relative sliding between the two can also be prevented in other ways. For example, the inner sleeve 2 and the outer sleeve 1 can be made into a damped frictional contact, which can be achieved by placing felt on the outer surface of the inner sleeve 2 or the inner surface of the outer sleeve 1. Alternatively, the rotating sleeve 3 and the adjusting rod 4 can be made into a damped frictional contact.

[0041] The outer tube 1 is also equipped with a flip-up display module 13. The display module 13 can be flipped up and down, and the flipping axis is located at... Figure 1 The center is horizontal. The flipped view is visible. Figure 3 To maintain the stability of the display module 13, a first suction block 14 and a second suction block 15 are provided on the outer sleeve 1. Both the first suction block 14 and the second suction block 15 are made of iron. A magnet 131 is provided at the corresponding position of the display module 13.

[0042] Display module 13 in Figure 1 The display module 13 is in a stored state, at which point magnet 131 is attracted to the first attraction block 14. The display module 13 is protected while in the stored state. Figure 3 When the display module 13 is in the open state, magnet 131 is attracted to the second attraction block 15. The open state of the display module 13 facilitates observation of the displayed data, and the display module 13 can be configured as a touchscreen for convenient touch operation.

[0043] During operation, the extension length can be adjusted by pulling out the inner sleeve 2, thereby adjusting the overall length of the device. The position of the inner sleeve 2 after adjustment can be restricted by tightening and pressing the locking bolt 9. When in use, rotating the display module 13 causes the magnet 131 on the display module 13 to attract the second attraction block 15 on the upper part, thereby opening the display module 13. When the display module 13 is in the storage state, the screen is located on the inside, thereby avoiding damage from bumps.

[0044] When it is necessary to adjust the angle of the probe head 6 to detect the upper surface of an object at a height, the screw head 12 is turned. The rotation of the screw head 12 causes the adjusting rod 4 to rotate, which in turn causes the rotating sleeve 3 to rotate. The rotation of the rotating sleeve 3 causes the connecting shaft 5 to rotate, which in turn causes the end gear 7 to rotate. The rotation of the end gear 7 causes the deflection gear 8 that meshes with it to rotate, which in turn causes the rotating rod 11 to rotate. The rotation of the rotating rod 11 causes the probe head 6 to swing. The swinging of the probe head 6 thus achieves angle deflection, making it easier to detect the upper surface of an object at a height.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
