Description

Technical Field

[0001] The invention relates to the technical field of nondestructive testing, and in particular to an ultrasonic flaw detection device for ship shaft materials. Background Art

[0002] The ship shaft is a key component in the ship propulsion system. Since the ship shaft will produce internal defects such as pores, inclusions, cracks, etc. during the manufacturing process, new defects will also appear due to fatigue during long-term use. Ultrasonic flaw detection can effectively detect these internal defects, determine their location, size and shape, and avoid serious accidents such as shaft breakage during operation.

[0003] When inspecting ship shaft materials, traditional ultrasonic flaw detection devices usually pour the coupling agent directly from a large container. This can easily lead to excessive pouring, especially when the inspection area has a complex shape and needs to be applied multiple times. This results in serious waste, and it is difficult to accurately control the amount of coupling agent used, and it is impossible to ensure uniform application.

Two rotating wheels 3 are fixedly installed on the outer wall of each telescopic rod 4, two fourth motors 31 are fixedly installed on one side of the moving seat 8, and the output shafts of the two fourth motors 31 are fixedly connected to one end of the two telescopic rods 4 respectively. A lifting plate 17 is slidably installed in the moving frame 9, and a centralizing box 21 is fixedly installed at the bottom of the lifting plate 17. The ultrasonic flaw detector 16 is fixedly installed on one side of the centralizing box 21, and the bottom of the centralizing box 21 is sealed with a leak-proof plate 23.

The third motor 25 drives the fourth screw 29 to rotate through the output shaft to make the pressure plate 26 descend, and the coupling agent is squeezed out of the concentration box 21 by pressure. When the first ball 24 no longer contacts the ship shaft material, the porous tube 27 descends and the coupling agent is no longer discharged. According to the actual needs of the flaw detection part, an appropriate amount of coupling agent is accurately squeezed out, thereby avoiding the waste that may occur in the traditional method and reducing the cost.

[0025] The working principle of the ultrasonic flaw detection device for ship shaft materials provided by the present invention is as follows: First, place the ship shaft material on the two telescopic rods 4, start the fourth motor 31, and the output shaft of the fourth motor 31 drives the telescopic rod 4 to rotate. At this time, the ship shaft material continues to roll with the telescopic rod 4. When it is necessary to adjust the distance between the fixed seat 2 and the movable seat 8, start the first motor 11, and the output shaft of the first motor 11 drives the first screw 10 to rotate, so that the movable seat 8 moves toward the fixed seat 2, and the telescopic rod 4 begins to shorten. Turn the round-edged handwheel 5, and the lifting plate 17 is lowered through the third screw 18, so that the first ball 24 and the ultrasonic flaw detector 16 are in contact with the ship shaft material.

The water pump 20 passes through the second hard pipe 19 and the hose 14 and the first hard tube 6 begin to extract the coupling agent in the first box body 7 and transport the coupling agent to the central box 21. When the first ball 24 contacts the ship shaft material, the first ball 24 will drive the porous tube 27 to rise, so that the flow port on the porous tube 27 opens, and the coupling agent flows out. The third motor 25 is started, and the output shaft of the third motor 25 drives the rotating seat 28 to rotate, and the rotating seat 28 drives the fourth screw 29 to rotate, so that the pressing plate 26 descends, and the pressing plate 26 squeezes out the coupling agent, and the first ball 24 and the plastic scraper 22 cooperate to evenly apply the coupling agent on the ship shaft material, and the ultrasonic flaw detector 16 starts to detect the ship shaft material, so that the flaw detection work of the ship shaft material can be completed.

[0026] Compared with the related art, the ultrasonic flaw detection device for ship shaft material provided by the present invention has the following beneficial effects: The present invention provides an ultrasonic flaw detection device for ship shaft materials by cooperating with a first box body 7, a first hard tube 6, a valve 13, a hose 14, a second hard tube 19, a water pump 20, a pressure plate 26, a first spring 30, a first ball 24 and a porous cylinder 27. According to the device, a proper amount of coupling agent can be accurately extruded according to the actual needs of the flaw detection part, thereby avoiding the waste that may occur in the traditional method, reducing the cost, and the flaw detection personnel do not need to frequently go to the large cylinder to get the coupling agent, especially in the case of narrow space or special position of the ship shaft, which can reduce the operation time and difficulty and improve the work efficiency; by cooperating with a fixed seat 2, a rotating wheel 3, a telescopic rod 4, a movable seat 8, a first screw 10 and a first motor 11, since the lengths of ship shafts of different ships are different, the ultrasonic flaw detector 16 can adapt to ship shafts of various lengths, without the need to customize the ultrasonic flaw detector 16 for each ship shaft, and the position of the ultrasonic flaw detector 16 can also be accurately adjusted according to the length of the ship shaft, so that the ultrasonic probe is better coupled with the ship shaft, ensuring that the ultrasonic wave can be evenly and accurately transmitted and received.

[0027] Second embodiment: Based on the ultrasonic flaw detection device for ship axle materials provided in the first embodiment of the present application, the second embodiment of the present application provides another ultrasonic flaw detection device for ship axle materials. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0028] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figure 8-Figure 14The ultrasonic flaw detection device for the ship shaft material also includes a T-slot 32, which is arranged at the bottom of the lifting plate 17. A T-shaped fixing plate 33 is fixedly installed on the top of the central box 21. The T-shaped fixing plate 33 and the T-slot 32 are adapted. The T-shaped fixing plate 33 and the T-slot 32 are both provided with fixing holes, and a fixing bolt 34 is provided in the fixing hole. A connecting shaft 39 is fixedly installed on the top of the fourth screw rod 29, and a guide strip 41 is integrally formed on the outer wall of the connecting shaft 39. A circular clamping hole 38 is provided at the bottom of the rotating seat 28, and limiting grooves are provided on both sides of the circular clamping hole 38. The top of the connecting shaft 39 extends to The circular card hole 38 is arranged in the guide bar 41 and is matched with the limit groove. The bottom end of the connecting shaft 39 is fixedly installed with a ball card seat 40. A second mounting plate is fixedly installed in the ball card seat 40. A second ball 37 is arranged on the second mounting plate. A contact seat 36 is fixedly installed on the top of the leakage-proof plate 23. The second ball 37 contacts the contact seat 36. Limit blocks 43 are fixedly installed on both sides of the leakage-proof plate 23. U-shaped card seats 66 are fixedly installed on both sides of the central box 21. The top of the limit block 43 extends into the U-shaped card seat 66. The U-shaped card seat 66 and the limit block 43 are provided with connecting card holes. A clamping rod 44 is provided in the hole, and a first inclined surface is provided at one end of the clamping rod 44. A second inclined surface is also provided on the inner wall of the top of the connecting clamping hole on the limit block 43. The first inclined surface and the second inclined surface are adapted to each other. When the inclined surface on the clamping rod 44 contacts and is pushed with the inclined surface on the limit block 43, a pressure perpendicular to the inclined surface is generated. This pressure can be decomposed into horizontal and vertical components. The horizontal component forces the leak-proof plate 23 and the central box 21 to be squeezed against each other in the horizontal direction, thereby achieving fastening, and the vertical component forces help to make the contact surfaces of the two more closely fit, thereby reducing the gap between the sealing rings. The gap between the two ends of the central box 21 and the central box 21 is formed, thereby preventing the internal coupling agent from leaking. A plurality of second threaded holes 45 and a first threaded hole 42 are respectively provided on the clamping rod 44 and the U-shaped clamping seat 66, and the plurality of second threaded holes 45 are adapted to the plurality of first threaded holes 42. The first threaded hole 42 and the second threaded hole 45 are provided with the same threaded bolt 46. A circle of sealing ring is fixedly installed on the top of the leakage-proof plate 23, so that the sealing ring is inserted into the sealing groove at the bottom of the central box 21. When the clamping rod 44 is inserted into the connecting clamping hole on the U-shaped clamping seat 66 and the limit block 43, the leakage-proof plate 23 and the central box 21 can be fixed to prevent the coupling agent from leaking.

[0030] The second mounting plate is provided with a second pocket hole, and the second ball 37 is movably inlaid in the second pocket hole.

[0031] When it is necessary to clean the inside of the centralized box 21, first use a tool to remove the fixing bolt 34, slide the centralized box 21 out, then use a tool to remove the threaded bolt 46 in the first threaded hole 42, and then pull out the clamping rod 44 to separate the leak-proof plate 23 and the centralized box 21, pull out the fourth screw 29 from the rotating seat 28, and then remove the pressing plate 26 from the fourth screw 29, and then the components in the centralized box 21 can be cleaned. When installing, put the pressing plate 26 on the top of the fourth screw 29, and then align the connecting shaft 39 and the guide strip 41 with the circular clamping hole 38 on the rotating seat 28. After plugging in, cover the leak-proof plate 23 on the bottom of the centralized box 21, make sure that the second ball 37 is located in the contact seat 36, and then clamp the clamping rod 44 in the connecting clamping hole, and use the threaded bolt 46 to fix the clamping rod 44, thus completing the leak-proof The disassembly and installation of the plate 23 and the central box 21. The present invention arranges the above-mentioned components so that the pressure plate 26 can continuously apply downward pressure to the coupling agent when it descends, so that the coupling agent can be stably squeezed out of the central box 21 during use, avoiding the situation where the extrusion is not smooth or the flow is unstable due to factors such as the uneven distribution of the gravity of the coupling agent itself or the deformation of the central box 21. The pressure plate 26 can also fully squeeze the coupling agent to the cylinder outlet, so that the coupling agent in the cylinder can be used more thoroughly and the residue can be reduced. The structure in the central box 21 can be regularly disassembled for thorough cleaning to prevent the coupling agent residue from drying and adhering to the inner wall of the central box 21, so as to avoid contamination of the coupling agent used subsequently, thereby ensuring the purity and performance of the coupling agent and avoiding the chemical components in the residual coupling agent from corroding or otherwise damaging the material of the central box 21, thereby extending the service life of the central box 21.

When the coupling agent in the first box 7 is used up, it can be extracted from the third box 48 in time for use, avoiding the suspension of the flaw detection work due to the interruption of the coupling agent supply. The top of the base 1 is fixedly installed with a third box 48, and the top of the third box 48 is provided with a first opening. A double-pass box 57 is rotatably installed on the third box 48. Both sides of the double-pass box 57 are integrally formed with a first fixing rod. The top of the third box 48 is fixedly installed with a fifth motor 55. The output shaft of the fifth motor 55 is fixedly connected to one end of the first fixed rod, a dustproof plate 52 is installed in the first opening, and second fixed rods are integrally formed on both sides of the dustproof plate 52. The ends of the two second fixed rods that are away from each other are rotatably connected to the inner walls of the two sides of the first opening, and the outer walls of the corresponding second fixed rods are fixedly installed with second gears 58. The top of the third box body 48 is rotatably installed with a third fixed rod, and one end of the third fixed rod is fixedly installed with a first gear 53. The first gear 53 is meshed with the second gear 58. The outer walls of the first fixed rod and the third fixed rod are fixedly installed with pulleys, and the outer sides of the two pulleys are sleeved with the same belt 54. A movable frame 60 is slidably installed in the double-pass box 57, and one side of the movable frame 60 is inside Two second filters 62 are hinged on the wall, two limit bars are fixedly installed on the inner wall of the movable frame 60, both limit bars are provided with grooves, a movable plate 63 is slidably installed in the groove, a pressure sensor 65 is fixedly installed in the groove, the bottom of the second filter 62 contacts the top of the movable plate 63, second openings are opened on both sides of the movable frame 60, and the first filter 61 is fixedly installed in the second openings. The top of the base 1 is also fixedly installed with a fourth box body 51, a garbage storage box 59 is provided in the fourth box body 51, and one end of the spray pipe 56 is also fixedly installed in the fourth box body 51, and the other end of the spray pipe 56 extends to the outside of the fourth box body 51, and the water pipe is connected to the spray pipe 56, and the water sprayed from the spray pipe 56 will move the movable frame 6 0, and the second filter screen 62 and the first filter screen 61 are cleaned, while impurities and metal wires are concentrated on the garbage collection box 59. The staff can take out the garbage collection box 59, and the remaining waste water is discharged from the sewage pipe 49. A third hard pipe 50 is provided in the third box body 48, and one end of the third hard pipe 50 extends to the outside of the third box body 48 and is fixedly connected to the second water inlet end of the valve 13. The second filter screen 62 will filter out impurities and metal wires in the coupling agent. When the metal wires and impurities on the two second filter screens 62 are concentrated too much, the second filter screen 62 will be driven to descend, and one end of the second filter screen 62 will drive the movable plate 63 to descend and contact with the pressure sensor 65. At this time, the fifth motor 55 is started and the movable frame 60 begins to be cleaned.

[0035] One ends of two third springs 64 are fixedly mounted on the bottom of the movable plate 63 , and the other ends of the two third springs 64 are fixedly mounted on the limiting bar.

[0036] A sewage pipe 49 is fixedly installed on one side of the fourth box body 51, and a plurality of filter holes are provided at the bottom of the garbage storage box 59.

[0037] When the coupling agent is applied to the ship shaft material, part of the coupling agent will drip onto the arc collecting plate 47 and slide into the third box 48 through the arc collecting plate 47. When the coupling agent drips from the arc collecting plate 47 into the third box 48, the second filter 62 will filter out impurities and metal wires in the coupling agent. When too much metal wire and impurities are concentrated on the two second filter screens 62, the second filter screens 62 will be driven to drop, and one end of the second filter screen 62 will drive the movable plate 63 to drop and contact with the pressure sensor. 65, at this time, the fifth motor 55 is started, and the output shaft of the fifth motor 55 drives the double-pass box 57 to rotate. While the double-pass box 57 is rotating, the dust-proof plate 52 is driven to rotate through the belt 54, so that the double-pass box 57 can be rotated out of the third box body 48. When the double-pass box 57 rotates 90 degrees, the movable frame 60 slides out into the fourth box body 51, and the water pipe is connected to the spray pipe 56. The water sprayed by the spray pipe 56 cleans the second filter screen 62 and the first filter screen 61 on the movable frame 60, and Impurities and metal wires are concentrated on the garbage collection box 59. The staff can take out the garbage collection box 59, and the remaining waste water is discharged from the sewage pipe 49. Then the fifth motor 55 is started again to reverse the output shaft of the fifth motor 55, so that the double-pass box 57 returns to its original position. The present invention collects the dripping coupling agent and extracts it for use when needed through the arrangement of the above-mentioned components, so that the coupling agent can be fully utilized and the waste caused by accidental dripping of the coupling agent can be reduced. When the coupling agent in another tube is used up, it can be extracted from the collection tube in time for use, avoiding the suspension of the flaw detection work due to the interruption of the coupling agent supply. Impurities, particles and other contaminants in the coupling agent can be removed to prevent them from affecting the propagation and reflection of ultrasonic waves, as well as wearing the ultrasonic probe or clogging the pipeline. Installing a filtering device can reduce the wear and clogging of these components, extend the service life of the equipment, and enable the clean coupling agent to better form a good coupling between the probe and the ship's shaft, improve the coupling efficiency, and transmit the ultrasonic energy more effectively.
