Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of metal detection equipment, and particularly relates to a water immersion ultrasonic detection bracket based on metal detection. Background Technique
[0002] Ultrasonic testing methods include the contact method, electromagnetic coupling method, and immersion method. Among them, the contact method requires the ultrasonic probe to be in direct contact with the workpiece, and the probe is easily worn; since the sound signal amplitude will decrease by 107 dB and 96 dB for every distance increase of one winding wavelength of the coil from the workpiece surface, which will cause a large error in the detection result, the electromagnetic coupling method requires that the gap between the high-frequency coil and the workpiece cannot be too large; in the immersion method, the probe does not directly contact the workpiece, so this method is suitable for specimens with rough surfaces, the probe is not easily worn, the coupling is stable, the detection result has good repeatability, and it is convenient for detection. The coupling agent for the immersion method can be water and oil. Since water is cheap and easily available, water immersion ultrasonic detectors are more widely used in actual engineering.
[0003] During the use of a water immersion ultrasonic detector, the device needs to be fixed on a fixed frame, and the position of the object to be measured is manually adjusted so that a part of the object to be measured contacts the induction end of the detector for measurement. When measuring a metal object, since many metal objects themselves are heavy in material weight, it is rather laborious to manually adjust the position to be measured. Content of the Utility Model
[0004] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a water immersion ultrasonic detection bracket based on metal detection. Through the slide rail on the chassis and the connecting rod on the rotation adjustment structure, the induction end of the ultrasonic detector rotates relative to the surface of the object to be measured, and through the setting of the translation adjustment structure and the lifting cylinder, the induction end translates relative to the surface of the object to be measured, and different positions of the object to be measured can be measured without manually adjusting the object to be measured.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A water immersion ultrasonic detection bracket based on metal detection, including a chassis, a translation adjustment structure, and a rotation adjustment structure. The translation adjustment structure is located on the chassis, and the rotation adjustment structure is located on the translation adjustment structure;
[0006] An outer slide rail and an inner slide rail are formed on the chassis. Two rotation pulleys are arranged at the bottom of the translation adjustment structure, and the two rotation pulleys respectively fit with the two slide rails;
[0007] The translation adjustment structure includes a top plate. A lifting cylinder is arranged at the bottom of the top plate, and a horizontal slide rail and a vertical slide rail are formed on the top plate;
[0008] The rotation adjustment structure includes a fixed plate and a connecting rod. The fixed plate is rotatably connected to the inner wall of the connecting rod, and the fixed plate is connected to an ultrasonic detector.
[0009] Preferably, the chassis is a disc-shaped structure. The outer slide rail is located on the outer periphery of the chassis. The outer slide rail is recessed inward along the diameter direction. The inner slide rail is located on the inner periphery of the chassis. The inner slide rail protrudes outward along the diameter direction. The movement of the rotating pulley along the diameter direction is limited by the side wall of the slide rail.
[0010] Preferably, the translation adjustment structure further includes a bottom plate, a first connecting pipe, and a second connecting pipe. The number of the first connecting pipes is multiple. The first connecting pipes are fixed at the edge position of the bottom plate. The first connecting pipes are hollow pipes. A second connecting pipe is inserted into any one of the first connecting pipes. The second connecting pipe is fixedly connected to the lower end of the top plate. The lifting cylinder is fixed on the bottom plate. The telescopic end of the lifting cylinder abuts against the lower end of the top plate. The top plate is driven by the lifting cylinder to move in a direction perpendicular to the ground. The top plate is supported by the first connecting pipe and the second connecting pipe to prevent the top plate from tilting relative to the bottom plate.
[0011] Preferably, the horizontal slide rail is located on the upper end surface of the top plate. The horizontal slide rail is an L-shaped slide rail. The number of the horizontal slide rails is two. The path direction of the L-shaped long axis of any one of the horizontal slide rails is the same as the direction of the distance between the two rotating pulleys. The vertical slide rail is located on the side surface of the top plate. The number of the vertical slide rails is two. The path direction of any one of the vertical slide rails is perpendicular to the path direction of the horizontal slide rail. The position settings of the horizontal slide rail and the vertical slide rail enable the translation pulley to change tracks and slide between the two slide rails.
[0012] Preferably, the rotation adjustment structure further includes translation pulleys. The number of the connecting rods is two, and the number of the translation pulleys is also two. The bottoms of the two connecting rods are connected to the two translation pulleys in a one-to-one correspondence. The translation pulleys, the horizontal slide rail, and the vertical slide rail fit each other. The fixed plate and the translation pulley move synchronously in the slide rail direction through the connecting rod.
[0013] Preferably, the rotation adjustment structure further includes a rotating rod. The rotating rod is a Z-shaped rod. One side of the horizontal axis of the rotating rod penetrates through the connecting rod and is inserted into the fixed plate. A damper is arranged at the connection between the rotating rod and the connecting rod. The force required for the rotating rod to rotate is limited by the damper to prevent the rotating rod from automatically rotating under the influence of weight.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] Through the sliding connection between the sliding rail on the chassis and the rotating pulley, the ultrasonic detector is driven to rotate around the side of the object to be measured. Through the rotating plate rotatably connected to the inner wall of the connecting rod, the ultrasonic detector is driven to rotate with the connecting rod as the rotation axis. And through the telescopic end of the telescopic cylinder being connected to the top plate with a horizontal sliding rail and a vertical sliding rail, the ultrasonic detector is driven to perform three-way translation movement in the three-dimensional space of X, Y, and Z, so that the sensing end of the ultrasonic detector can freely move on the side and end surfaces of the object to be measured.

The fixing plate 33 is rotatably connected to the inner wall of the connecting rod 31, and an ultrasonic detector 4 is fixedly connected to the fixing plate 33.
[0029] The translation adjustment structure further includes a bottom plate 21, a first connecting pipe 22 and a second connecting pipe 23. The bottom plate 21 is a rectangular plate. The number of the first connecting pipes 22 is four, and the four first connecting pipes 22 are located at the corners of the bottom plate 21. The first connecting pipe 22 is a hollow pipe. The second connecting pipes 23 are inserted into the four first connecting pipes 22 in a one-to-one correspondence. The second connecting pipe 23 is fixedly connected to the lower end of the top plate 24. The second connecting pipe 23 moves telescopically along the inner wall direction of the first connecting pipe 22. The first connecting pipe 22 and the second connecting pipe 23 support the top plate 24. The lifting cylinder 5 is fixed on the bottom plate 21, and the telescopic end of the lifting cylinder tightly abuts against the lower end of the top plate 24. The lifting of the lifting cylinder drives the top plate 24 to move in a direction perpendicular to the ground. The horizontal slide rail 241 is located on the upper end surface of the top plate 24. The horizontal slide rail 241 is an L-shaped slide rail. The number of the horizontal slide rails 241 is two. The path direction of the L-shaped long axis of any one of the horizontal slide rails 241 is the same as the direction of the distance between the two rotating pulleys 7. The vertical slide rail 242 is located on the side of the top plate 24. The number of the vertical slide rails 242 is two. The path direction of any one of the vertical slide rails 242 is perpendicular to the path direction of the horizontal slide rail 241.
[0030] The rotation adjustment structure 3 further includes a translation pulley 32 and a rotating rod 35. The number of the connecting rods 31 is two, and the number of the translation pulleys 32 is also two. The bottoms of the two connecting rods 31 are connected to the two translation pulleys 32 in a one-to-one correspondence.

One side horizontal axis of the rotating rod 35 penetrates through the connecting rod 31 and is inserted into the fixing plate 33. A damper 34 is provided at the connection between the rotating rod 35 and the connecting rod 31. The damper 34 restricts the fixing plate 33 from rotating around the connecting rod 31 in the natural state.
[0031] The chassis 1 has a disc-shaped structure.

[0032] The implementation principle of Embodiment 1 of this application is as follows: When it is necessary to detect the top of the object 6 to be measured, referring to Figure 6 , push the two connecting rods 31 along the transverse slide rail 241, so that the ultrasonic detector 4 on the fixed plate 33 moves synchronously above the object 6 to be measured. Then rotate the rotating rod 35 to drive the fixed plate 33 to rotate and drive the ultrasonic detector 4 to rotate synchronously until the sensing end of the ultrasonic detector 4 faces the top of the object 6 to be measured. Subsequently, adjust the length of the telescopic end of the lifting cylinder 5, so that the top plate 24 moves in a direction perpendicular to the ground, driving the ultrasonic detector 4 to move synchronously until the sensing end is in close contact with the top of the object 6 to be measured. Finally, continuously rotate and translate the adjustment structure 2 along the outer slide rail 11 and push the connecting rod 31 along the transverse slide rail 241, so that the sensing end of the ultrasonic detector 4 comes into contact with all positions of the top of the object 6 to be measured in sequence, realizing a full detection of the top of the object 6 to be measured;
[0033] When it is necessary to detect the side of the object 6 to be measured, referring to Figure 7 , push the two connecting rods 31 along the L-shaped transverse slide rail 241 to the end position, and then the ultrasonic detector 4 rotates 90 degrees compared with the initial position. At this time, the sensing end of the ultrasonic detector faces the side of the object 6 to be measured. Then push the connecting rod 31 along the vertical slide rail 242, so that the sensing end of the ultrasonic detector moves horizontally on the side of the object 6 to be measured. At the same time, the telescopic end of the lifting cylinder 5 is adjusted telescopically, so that the sensing end of the ultrasonic detector moves vertically on the side of the object 6 to be measured. After fully detecting this side, rotate and translate the adjustment structure 2 along the outer slide rail 11, so that the sensing end of the ultrasonic detector faces the next side and repeat the detection process until all sides are detected.
