Description

Technical Field

[0001] The utility model relates to a flaw detection device, in particular to an ultrasonic flaw detection device for ring forgings. Background Art

[0002] Currently, ultrasonic flaw detection of ring forgings is performed manually using handheld flaw detection equipment or automatically using automatic flaw detection devices. However, due to the limitations of the handheld device probe, the manual handheld flaw detection method only covers a limited area per unit time, resulting in low detection efficiency. Therefore, currently, automated flaw detection equipment is mostly used for flaw detection of ring forgings.

[0003] A Chinese patent with publication number "CN219737380U" discloses a fully immersion ultrasonic flaw detection device for annular workpieces. The device immerses the workpiece in a water tank and supports the annular workpiece through a number of support rollers in the water tank. Then, a probe is driven by a robotic arm on one side of the water tank to perform ultrasonic flaw detection on the annular workpiece in the water tank.

[0004] While this fully immersion ultrasonic flaw detection device achieves good ultrasonic flaw detection results on annular workpieces, it requires the workpiece to be placed horizontally in a water tank during testing, which increases the difficulty of lifting the workpiece. The lifting equipment requires specialized lifting tools, and the workpiece is prone to tipping during the lifting process. Furthermore, while the use of a robotic arm to drive the probe for flaw detection offers high detection efficiency, the equipment also comes with high installation and maintenance costs. Furthermore, due to the fully immersion method, the amount of water required for testing is also high.

[0005] Chinese patent publication number "CN218646909U" discloses a fully automatic surface flaw detection device for ring forgings. The device supports the workpiece via two rotating shafts on the surface of a bracket. A motor drives the shafts and the workpiece on them to rotate, enabling a probe above the workpiece to inspect the workpiece. While this device addresses the aforementioned issues of difficult workpiece hoisting and high inspection costs, the workpiece is placed on the shaft during inspection, with its circumferential surface in contact with the shaft. Ring forgings are mostly short, flat, and easily tip over or even become unstable if placed directly on the shaft. Therefore, a new type of ring forging flaw detection device is needed to address these issues. Summary of the Invention

[0006] In order to solve the above technical problems, the utility model provides an ultrasonic flaw detection device for ring forgings, which is easy to load, does not easily overturn the workpiece during detection, and has low detection cost.

[0007] The ultrasonic flaw detection device for ring forgings of the present invention comprises a water trough, and the ultrasonic flaw detection device for ring forgings also comprises a base plate, the top of the base plate is located above the water trough, the bottom of the base plate is located in the water trough, a plurality of driving wheel assemblies and driven wheel assemblies are provided on the surface of the base plate, the driving wheel assemblies and the driven wheel assemblies each comprise a mounting box and a support roller, the mounting box is fixedly connected to the base plate, the support roller is rotatably arranged on the mounting box, the mounting box of the driving wheel is further provided with a driving motor for driving the support roller to rotate, a probe assembly is further provided in the water trough, the probe assembly comprises a column at one end connected to the water trough, and a plurality of beams for mounting the probes are provided on the column.

[0008] The advantage of the ultrasonic flaw detection device for ring forgings is that it includes a base plate with its bottom located in a water tank, a plurality of driving wheel assemblies and driven wheel assemblies are provided on the surface of the base plate, a driving motor capable of driving the support roller to rotate is provided on the mounting box of the driving wheel, and a probe assembly for flaw detection of the ring forgings is also provided in the water tank.

[0009] Compared with the existing fully immersion ultrasonic flaw detection device, this ring forging ultrasonic flaw detection device can drive the ring forging to rotate through the active wheel assembly. Since the top of the base plate is located above the water tank and the bottom is located in the water tank, different parts of the ring forging can be immersed in the water tank in turn, thereby enabling the ring forging ultrasonic flaw detection device to maintain high detection efficiency while reducing the water requirement for detection.

[0010] Furthermore, due to the baseplate and its arrangement of driving and driven wheel assemblies, the hoisting device can connect the ring forgings with a simple hook or sling and hoist them onto a number of support rollers during loading. After loading, the upper and lower ends of the ring forgings are supported by support rollers on the upper and lower sides of the baseplate surface, respectively, making loading of the ring forgings easier for operators. During testing, although the flat ring forgings are essentially vertical, they are not easily overturned during rotation because their bottom end is supported by the support rollers below them and their top end is restrained by the support rollers above them.

[0011] Compared with the existing flaw detection equipment that uses a robotic arm to drive the probe for detection, the probe assembly of the ring forging ultrasonic flaw detection device is installed with several probes through the column and the beam. During detection, the ring forging is driven to rotate by the active wheel assembly, thereby realizing comprehensive inspection and flaw detection of the ring forging. Therefore, its equipment deployment cost and subsequent maintenance cost are also relatively low.

[0012] Furthermore, in the ultrasonic flaw detection device for ring forgings of the present invention, the substrate is tiltedly arranged in the water tank, and the angle between the surface of the substrate and the bottom surface of the water tank is greater than 90 degrees and less than 180 degrees.

[0013] The base plate is placed in the water tank at an angle, so that after the ring forging is loaded, it can tilt toward the base plate under the action of gravity to fit tightly against the surface of the installation box. Since the base plate is tilted to one side, the ring forging is less likely to tip over when it rests against the surface of the installation box.

[0014] Furthermore, in the ultrasonic flaw detection device for ring forgings of the present invention, a plurality of rollers are provided on the surface of the mounting box.

[0015] The setting of the roller reduces the friction between the mounting box and the ring forging when the ring forging rotates, thereby preventing the mounting box from scratching the surface of the ring forging and causing damage to the surface.

[0016] Furthermore, in the ultrasonic flaw detection device for ring forgings of the present invention, a group of driving wheel assemblies and two groups of driven wheel assemblies are provided on the surface of the base plate, one group of driven wheel assemblies is arranged on the top of the base plate, and the other group of driven wheel assemblies and the driving wheel assembly are distributed on the bottom of the base plate.

[0017] This arrangement makes the ring forgings on the driving wheel assembly and the driven wheel assembly rotate more stably and are not likely to fall off the support roller during inspection.

[0018] Furthermore, in the ultrasonic flaw detection device for ring forgings of the present invention, the bottom end of the column is fixedly arranged on the bottom surface of the water tank, two crossbeams are arranged in parallel on the upper part of the column, and a plurality of probes are respectively arranged on the crossbeams.

[0019] The setting of two crossbeams enables comprehensive detection of the inner and outer circumferences of the ring forging.

[0020] Furthermore, in the ultrasonic flaw detection device for ring forgings of the present invention, a U-shaped protective hook is also provided on the column.

[0021] The provision of the U-shaped protective hook further protects the ring forging to prevent the ring forging from falling off the support roller.

[0022] Furthermore, in the ultrasonic flaw detection device for ring forgings of the present invention, a lift is provided on the column, a body of the lift is fixed on the column, and an output end of the lift is connected to the U-shaped protective hook.

[0023] The setting of the elevator on the column enables the ultrasonic flaw detection device to drive the U-shaped protective hook to rise and fall through the elevator, thereby facilitating the loading and unloading of ring forgings.

[0024] Furthermore, the ultrasonic flaw detection device for ring forgings of the present invention also includes a support frame, which includes a frame body behind the water tank, the top of the frame body is a detection cabin, and an inclined support is provided on the front side of the frame body, and the base plate is installed on the inclined support.

[0025] The arrangement of the support frame, the inspection cabin and other components facilitates the installation and maintenance of the driving wheel assembly and the driven wheel assembly by the operators.

[0026] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it in accordance with the contents of the specification, the following embodiments of the present invention are described in detail.

DETAILED DESCRIPTION

[0039] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] Example 1: See Figures 1 to 11The ultrasonic flaw detection device for ring forgings of this embodiment includes a water tank 1. The ultrasonic flaw detection device for ring forgings also includes a base plate 2. The top of the base plate is located above the water tank, and the bottom of the base plate is located in the water tank. A plurality of driving wheel assemblies 3 and driven wheel assemblies 4 are provided on the surface of the base plate. The driving wheel assembly and the driven wheel assembly both include an installation box 5 and a support roller 6. The installation box is fixedly connected to the base plate, and the support roller is rotatably arranged on the installation box. A driving motor for driving the support roller to rotate is also provided on the installation box of the driving wheel. A probe assembly 7 is also provided in the water tank. The probe assembly includes a column 8 connected to the water tank at one end, and a plurality of beams 9 for installing the probe are provided on the column.

[0041] The advantage of the ultrasonic flaw detection device for ring forgings is that it includes a base plate with its bottom located in a water tank, a plurality of driving wheel assemblies and driven wheel assemblies are provided on the surface of the base plate, a driving motor capable of driving the support roller to rotate is provided on the mounting box of the driving wheel, and a probe assembly for flaw detection of the ring forgings is also provided in the water tank.

[0042] Compared with the existing fully immersion ultrasonic flaw detection device, this ring forging ultrasonic flaw detection device can drive the ring forging to rotate through the active wheel assembly. Since the top of the base plate is located above the water tank and the bottom is located in the water tank, different parts of the ring forging can be immersed in the water tank in turn, thereby enabling the ring forging ultrasonic flaw detection device to maintain high detection efficiency while reducing the water requirement for detection.

[0043] Furthermore, due to the baseplate and its arrangement of driving and driven wheel assemblies, the hoisting device can connect the ring forgings with a simple hook or sling and hoist them onto a number of support rollers during loading. After loading, the upper and lower ends of the ring forgings are supported by support rollers on the upper and lower sides of the baseplate surface, respectively, making loading of the ring forgings easier for operators. During testing, although the flat ring forgings are essentially vertical, they are not easily overturned during rotation because their bottom end is supported by the support rollers below them and their top end is restrained by the support rollers above them.

[0044] Compared with the existing flaw detection equipment that uses a robotic arm to drive the probe for detection, the probe assembly of the ring forging ultrasonic flaw detection device is installed with several probes through the column and the beam. During detection, the ring forging is driven to rotate by the active wheel assembly, thereby realizing comprehensive inspection and flaw detection of the ring forging. Therefore, its equipment deployment cost and subsequent maintenance cost are also relatively low.

[0045] The water tank is used to hold water to immerse the bottom of the ring forging, so that the probe can detect flaws on the bottom.

[0046] The base plate is used to install the driving wheel assembly and the driven wheel assembly, thereby achieving support and rotation of the ring forging.

[0047] In this embodiment, the base plate is rectangular and has a through hole 10 at its bottom for accommodating the probe assembly. The mounting boxes of the driving wheel assemblies and the driven wheel assemblies are fixedly mounted on the front surface of the base plate.

[0048] Preferably, the base plate can be tilted within the water tank. Specifically, the angle between its front surface and the bottom of the water tank is greater than 90 degrees and less than 180 degrees. This allows the ring forging to tilt toward the base plate after loading under the action of gravity, allowing it to adhere closely to the surface of the installation box. The tilted base plate makes it less likely for the ring forging to tip over while resting against the surface of the installation box.

[0049] In order to reduce the friction between the mounting box and the ring forging during rotation and prevent the mounting box from scratching and damaging the surface of the ring forging, a plurality of rollers 11 may be provided on the surface of the mounting box to reduce the friction between it and the workpiece.

[0050] The driving wheel assembly and the driven wheel assembly are used to support the ring forging and achieve rotational drive of the ring forging. Specifically, each of the driving wheel assembly and the driven wheel assembly includes an installation box. In this embodiment, the installation box is a rectangular parallelepiped installation box fixedly mounted on the front surface of the base plate. Support rollers are mounted at the bottom end of the installation box. The main shaft of the support rollers can be mounted on the installation box via bearings. The installation box of the driving wheel assembly is also equipped with a drive motor. The drive motor body can be located within the installation box or on the surface of the installation box. Its output shaft is connected to the main shaft of the support roller of the driving wheel assembly. During testing, the drive motor drives the ring forging to rotate via the support roller of the driving wheel assembly, so that its bottom end can be immersed in the water tank.

[0051] In this embodiment, the ultrasonic flaw detection device for ring forgings includes a driving wheel assembly and two driven wheel assemblies. One driven wheel assembly is mounted on the top of a baseplate, while the other driven wheel assembly and driving wheel assembly are mounted in a box arranged in a figure-eight configuration at the bottom of the baseplate. During testing, the outer circumference of the bottom of the ring forging rests on the surfaces of two support rollers at the bottom of the baseplate, while the inner circumference of the top of the ring forging rests on the surfaces of the support rollers at the top of the baseplate.

[0052] The probe assembly, used to detect flaws in ring forgings, consists of a column and a beam mounted on the column for mounting the probe, an immersion ultrasonic probe. In this embodiment, the probe assembly is located at a perforation in the baseplate's bottom. The bottom end of the column is fixed to the bottom of the water tank. Two beams are parallel to the upper portion of the column, and several probes are mounted on each beam. During testing, the two beams are positioned above and below the bottom of the ring forging, respectively, allowing for flaw detection on both the inside and outside of the ring forging.

[0053] During hoisting, the end faces of the ring forgings lie within the vertical plane. During loading, the ring forgings are driven by the hoisting equipment from the front side of the base plate onto a number of support rollers. At this point, the bottom of the ring forging rests on the surfaces of the two lower support rollers, while its bottom end is submerged below the liquid level in the water tank. Two crossbeams are positioned above and below the bottom of the ring forging, with the top end of the ring forging resting on the support rollers on the upper portion of the base plate. After loading, the drive motor rotates the ring forging via the support rollers of the driving pulley assembly, while a probe simultaneously inspects the ring forging for flaws.

[0054] To further facilitate loading, the crossbeam can be moved by a horizontal displacement drive so that the workpiece can be easily lifted onto the support rollers.

[0055] Furthermore, a U-shaped protective hook 12 can be provided on the column to prevent the ring forging from falling off the support roller. The U-shaped protective hook can be fixedly provided on the column or installed at the output end of the elevator 13 on the column to achieve lifting and lowering, thereby facilitating the loading and unloading of the ring forging.

[0056] To facilitate installation of the baseplate, the ring forging ultrasonic flaw detection device also includes a support frame 14. The support frame comprises a frame 15 located behind the water tank, with an inspection cabin 16 located at the top and a diagonal brace 17 at the front, on which the baseplate is mounted. The inspection cabin facilitates installation and maintenance of components such as the driving and driven wheel assemblies. Its overall frame-like structure features an entrance and exit 18 at its bottom, connected to the bottom of the frame by a ladder 19, making it easy for operators to enter and exit the inspection cabin.

[0057] The control cabinet 20 and other equipment are set below the detection cabin to power and control the driving wheel assembly, probe assembly and other components, and can control the water level in the water tank through a water pump and a liquid level gauge.

[0058] Preferably, the substrate is arranged obliquely in the water tank, and the angle between the surface of the substrate and the bottom surface of the water tank is greater than 90 degrees and less than 180 degrees.

[0059] The base plate is tilted in the water tank so that the ring forging 21 can tilt toward one side of the base plate under the action of gravity after loading so as to be in close contact with the surface of the installation box. Since the base plate is tilted toward one side, the ring forging leaning against the surface of the installation box is less likely to overturn.

[0060] Preferably, a plurality of rollers are provided on the surface of the installation box.

[0061] The setting of the roller reduces the friction between the mounting box and the ring forging when the ring forging rotates, thereby preventing the mounting box from scratching the surface of the ring forging and causing damage to the surface.

[0062] Preferably, a group of driving wheel assemblies and two groups of driven wheel assemblies are provided on the surface of the substrate, one group of driven wheel assemblies is arranged on the top of the substrate, and the other group of driven wheel assemblies and the driving wheel assembly are distributed on the bottom of the substrate.

[0063] This arrangement makes the ring forgings on the driving wheel assembly and the driven wheel assembly rotate more stably and are not likely to fall off the support roller during inspection.

[0064] Preferably, the bottom end of the column is fixedly arranged on the bottom surface of the water tank, two crossbeams are arranged in parallel on the upper part of the column, and a plurality of probes are respectively arranged on the crossbeams.

[0065] The setting of two crossbeams enables comprehensive detection of the inner and outer circumferences of the ring forging.

[0066] Preferably, a U-shaped protective hook is also provided on the column.

[0067] The provision of the U-shaped protective hook further protects the ring forging to prevent the ring forging from falling off the support roller.

[0068] Preferably, a lift is provided on the column, the body of the lift is fixed on the column, and the output end of the lift is connected to the U-shaped protective hook.

[0069] The setting of the elevator on the column enables the ultrasonic flaw detection device to drive the U-shaped protective hook to rise and fall through the elevator, thereby facilitating the loading and unloading of ring forgings.

[0070] Preferably, a support frame is further included, which includes a frame body behind the water tank, the top of the frame body is a detection cabin, and a diagonal support is provided on the front side of the frame body, and the base plate is installed on the diagonal support.

[0071] The arrangement of the support frame, the inspection cabin and other components facilitates the installation and maintenance of the driving wheel assembly and the driven wheel assembly by the operators.
