Description

Technical Field

[0001] This utility model belongs to the field of detection technology, specifically relating to a multi-directional floating ultrasonic detection device. Background Technology

[0002] Ultrasonic testing is a method of inspecting steel plates by utilizing the characteristic that ultrasonic energy can penetrate deep into metal materials and reflect off the interface when it enters another interface. When an ultrasonic beam is incident from the surface of the object being inspected into the interior of the metal, it will generate a reflected wave at the defect surface when it encounters a defect, which is then displayed on a monitor.

[0003] When using an ultrasonic probe to inspect an object, a good fit between the probe and the object is necessary to ensure accurate results. For large objects such as steel plates, the ultrasonic probe needs to move continuously across the plate, resulting in extremely low efficiency for a single probe. Utility Model Content

[0004] To address the problem of low ultrasonic testing efficiency caused by uneven surfaces of the object being inspected, this invention provides a multi-directional floating ultrasonic testing device.

[0005] The embodiments of this utility model are achieved through the following technical solutions:

[0006] A multi-directional floating ultrasonic testing device includes a mobile trolley, which is equipped with a control component and an ultrasonic instrument, a display, a scanning encoder, and a testing mechanism electrically connected to the control component. The testing mechanism includes a probe scanning frame mounted on the front end of the mobile trolley. The probe scanning frame has a mounting surface capable of mounting three or more probe clamps. The probe clamps are adaptively telescopically connected to the probe scanning frame along the perpendicular direction of the mounting surface using elastic elements. Each probe clamp is equipped with an ultrasonic probe. The plane containing the swing trajectory of any ultrasonic probe, the plane containing the swing trajectory of the probe scanning frame, and the mounting surface are all mutually perpendicular.

[0007] As the surface of the object to be tested becomes irregular, the ultrasonic probe will exhibit a single or multiple free combination of movement trajectories in three directions: left and right, front and back, and up and down. At the same time, multiple ultrasonic probes will bounce up and down independently, which can achieve a more precise fit with the surface of the object to be tested. This design brings about a multi-directional adaptive floating detection structure, which can better match the uneven surface of the object to be tested and is suitable for large-area objects such as steel plates.

[0008] In some technical solutions of this utility model, the probe scanning frame includes a multi-channel probe frame with the mounting surface, and multiple probe clamps are telescopically connected to the multi-channel probe frame.

[0009] Adding a multi-channel probe holder design can reduce the difficulty of manufacturing parts.

[0010] In some technical solutions of this utility model, a nitrogen spring is provided between the probe scanning frame and the mobile trolley.

[0011] Nitrogen springs provide greater elasticity, resulting in better cushioning and allowing for a greater fit between the ultrasonic probe and the surface of the object being tested.

[0012] In some technical solutions of this utility model, the multi-channel probe frame is provided with multiple pins, one end of the pin is provided with a limiting block, and the other end passes through the multi-channel probe frame and is connected to the corresponding probe clamp. The pin is fitted with a helical spring, one end of the helical spring abuts against the multi-channel probe frame, and the other end abuts against the upper side of the probe clamp.

[0013] In this design, the pin acts as a guide, giving the ultrasonic probe a relatively stable buffering effect.

[0014] In some technical solutions of this utility model, the mobile trolley is hinged with a lifting assembly, and the lifting end of the lifting assembly is hinged to the probe scanning frame.

[0015] This design allows for quick lifting of the ultrasonic probe, preventing damage caused by moving the trolley during non-working hours; it also allows personnel to move the trolley freely during non-working hours.

[0016] In some technical solutions of this utility model, the above-mentioned lifting assembly includes a telescopic rod hinged to the probe scanning frame, and a pull wire flexible shaft controller is connected to the end of the telescopic rod away from the probe scanning frame. The pull wire flexible shaft controller is located on the mobile trolley.

[0017] This design uses a manual lifting detection mechanism, which can save on the operating costs of the detection device to some extent.

[0018] In some technical solutions of this utility model, the mobile trolley is hinged to a slide rail, and a sliding block is provided on the slide rail. The sliding block is hinged to the probe scanning frame.

[0019] The design of the slide rail and sliding block serves as a motion guide, enabling the probe scanning frame to move relatively stably up and down.

[0020] In some technical solutions of this utility model, the aforementioned mobile trolley is equipped with a water tank, a water pump, and a water spray pipe connected in sequence. The water pump is electrically connected to the aforementioned control components, and the free end of the water spray pipe passes through a multi-channel probe frame and is connected to a spray head.

[0021] This design enables rapid application of the coupling agent, preventing moisture evaporation from the coupling agent in hot weather.

[0022] In some technical solutions of this utility model, a monitoring camera is provided at the bottom of the mobile trolley, and an edge sensor is provided on the side of the mobile trolley. Both the monitoring camera and the edge sensor are electrically connected to the control components.

[0023] The monitoring camera allows personnel to see whether the ultrasonic probe at the bottom of the vehicle is in contact with the surface of the object being tested.

[0024] In some technical solutions of this utility model, a placement plate is slidably provided on the aforementioned mobile trolley, and the aforementioned control components and the aforementioned display are disposed on the placement plate.

[0025] This design allows personnel to adjust the height of the placement board according to their own height, making it easier to view the test data on the monitor.

[0026] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0027] In this ultrasonic testing device, a probe scanning frame is set at the front end of the mobile trolley, and multiple probe clamps that adaptively extend and retract within the probe scanning frame using elastic elements and multiple ultrasonic probes are set together. The plane on which the swing trajectory of any ultrasonic probe is located, the plane on which the swing trajectory of the probe scanning frame is located, and the mounting surface are all perpendicular to each other, so that the ultrasonic probe can move in multiple directions, better match the uneven surface of the object to be inspected, and adapt to large-area objects such as steel plates to be inspected.

[0037] Example

[0038] Please refer to Figures 1-3This embodiment provides a multi-directional floating ultrasonic testing device, including a mobile cart 1. The mobile cart 1 is equipped with a control component and an ultrasonic instrument 2, a display 3, a scanning encoder 4, and a testing mechanism 5 electrically connected to the control component. The testing mechanism 5 includes a probe scanning frame 6 installed at the front end of the mobile cart 1. The probe scanning frame 6 is provided with a mounting surface 25 that can install three or more probe clamps 8. The probe clamps 8 are adaptively telescopically connected to the probe scanning frame 6 along the perpendicular direction of the mounting surface 25 using elastic elements. Ultrasonic probes 9 are installed on the probe clamps 8. The plane where the swing trajectory of any ultrasonic probe 9 is located, the plane where the swing trajectory of the probe scanning frame 6 is located, and the aforementioned mounting surface 25 are all perpendicular to each other.

[0039] In the above embodiments, such as Figure 2 The mounting surface 25, indicated by the red line, is preferably oriented in the forward-backward direction of the moving trolley 1, and the direction of the swing trajectory of the ultrasonic probe 9 on the probe holder 8 is preferably oriented in the left-right direction of the moving trolley 1. The power supply for the electrical equipment on the ultrasonic testing trolley is achieved through a cable connection to a power source. The cable can be a mobile power source mounted on the frame or a fixed power source located at the testing site. When it is a fixed power source, the cable is equipped with a cable drag chain. The probe scanning frame 6 is equipped with an electrically controlled slide rail 16. A mounting bracket is connected to a slider on the electrically controlled slide rail 16. A movable rod is slidably mounted on the mounting bracket. A sliding spring is fitted on the movable rod. The two ends of the spring abut against the protrusion at the bottom of the movable rod and the mounting bracket, respectively. A scanning encoder 4 is connected to one end of the movable rod with the protrusion. The control components include a central processing unit, and the display 3 is preferably a laptop computer.

[0040] When ultrasonic testing is required on a large surface area, firstly, a coupling agent (preferably liquid water) is sprayed onto the surface of the object to be tested. Then, the moving carriage 1 is placed on the surface of the object to be tested, so that the detection mechanism 5 located at the front end of the moving carriage 1 is in contact with the surface of the object to be tested. The parameters of the equipment, such as frequency and gain, are adjusted according to the testing requirements. The central processing unit starts the ultrasonic instrument 2, the display 3, the scanning encoder 4, and the detection mechanism 5. During this process, the personnel manually push the moving carriage 1 slowly forward on the surface of the object to be tested. During this process, the ultrasonic probe 9 continuously emits ultrasonic pulses to the surface of the object to be tested. When the ultrasonic waves propagate in the object to be tested, they will be reflected when they encounter interfaces with different acoustic impedances (such as defects). The reflected ultrasonic signals are received by the ultrasonic probe 9 and converted into electrical signals. After the electrical signals are amplified and processed, the waveform or image is displayed on the computer screen by the central processing unit. When the ultrasonic probe 9 encounters the surface and the moving carriage 1 has completed its movement on the surface to be tested, the test is completed. During the inspection process, due to the irregularity of the surface of the object to be tested, pits or protrusions of different shapes will appear. When the direction of the pits and undulations is the direction of the trolley's movement, the ultrasonic probe 9 will swing back and forth relative to the object surface while floating up and down. When the direction of the pits and undulations is the left and right direction of the trolley, the ultrasonic probe 9 will swing left and right relative to the object surface while floating up and down. When the direction of the pits and undulations is in the middle position between the direction of the trolley's movement and the left and right direction, the ultrasonic probe 9 will float in three directions: left and right, front and back, and up and down. That is, during the operation, the trajectory of the ultrasonic probe 9 will show a single or multiple free combination of movement trajectories in the three directions of left and right, front and back, and up and down, thereby achieving a more precise fit with the surface of the object to be tested. This design brings a multi-directional adaptive floating inspection structure, which can better match the uneven surface of the object to be tested and is suitable for large-area objects such as steel plates.

[0041] It is also worth noting that the number of probe clamps 8 and ultrasonic probes 9 can be increased or decreased according to the actual situation; a placement slot is set at the rear of the mobile trolley 1, which can be used to place disassembled parts. When the mobile trolley 1 moves, the detection mechanism 5 at the front of the trolley can be disassembled and then placed in the placement slot. On the one hand, this can increase the counterweight at the rear of the mobile trolley 1, making the movement of the mobile trolley 1 more stable, and on the other hand, it can reduce the possibility of the ultrasonic probes 9 of the detection mechanism 5 at the front of the mobile trolley 1 colliding with obstacles in the workshop.

[0042] As a preferred embodiment, the probe scanning frame 6 includes a multi-channel probe frame 7 with the mounting surface 25, and multiple probe clamps 8 are adaptively telescopically connected to the multi-channel probe frame 7.

[0043] In the above embodiments, the design of adding a multi-channel probe holder 7 can reduce the processing difficulty of the parts.

[0044] In a preferred embodiment, a nitrogen spring 10 is provided between the probe scanning frame 6 and the mobile trolley 1.

[0045] In the above embodiments, the working pressure of the nitrogen spring 10 is typically between 10 and 150 bar ("bar" is a unit of pressure, defined as the pressure generated by a force of 106 dyns acting perpendicularly on an area of ​​1 square centimeter (cm2)). This provides greater elasticity, thereby providing a better buffering effect. At the same time, the nitrogen spring 10 has a long stroke and a constant spring force. By changing the working pressure of the nitrogen spring 10, its stiffness can be easily adjusted to adapt to different application requirements. The addition of the nitrogen spring 10 causes the ultrasonic probe 9 to be subjected to more pressure, preventing the ultrasonic probe 9 from rebounding too far, and making the ultrasonic probe 9 fit more closely to the surface of the object being tested.

[0046] In a preferred embodiment, the multi-channel probe holder 7 is provided with a plurality of pins 12. One end of each pin 12 is provided with a limiting block 26, and the other end passes through the multi-channel probe holder 7 and is connected to the corresponding probe clamp 8. A helical spring 13 is sleeved on the pin 12. One end of the helical spring 13 abuts against the multi-channel probe holder 7, and the other end abuts against the upper side of the probe clamp 8.

[0047] In the above embodiment, the pin 12 has a boss on the side near the probe holder 8, and the end of the helical spring 13 that abuts against the upper side of the probe holder 8 becomes abutting against the boss of the pin 12; in this design, the pin 12 plays a guiding role, so that the ultrasonic probe 9 has a relatively stable buffering effect; the design of the limiting block 26 can limit the movement stroke of the pin 12.

[0048] In a preferred embodiment, the mobile trolley 1 is hinged with a lifting assembly, and the lifting end of the lifting assembly is hinged to the probe scanning frame 6.

[0049] In the above embodiment, the lifting component can be an electrically controlled telescopic cylinder, the telescopic end of which is connected to the probe scanning frame 6. When the trolley is not working, the personnel can start the lifting component to drive the probe scanning frame 6 upward. This design can quickly lift the ultrasonic probe 9, avoiding damage to the ultrasonic probe 9 caused by moving the trolley 1 during non-working hours. It also allows personnel to move the trolley 1 freely during non-working hours.

[0050] In a preferred embodiment, the lifting assembly includes a telescopic rod 14 hinged to the probe scanning frame 6. The end of the telescopic rod 14 away from the probe scanning frame 6 is connected to a pull wire flexible shaft controller 15, which is mounted on the moving trolley 1.

[0051] In the above embodiment, it is preferable to use a pull-wire flexible shaft controller 15 with a self-locking structure. When the detection device does not need to work, the pull rod of the pull-wire flexible shaft controller 15 is pulled, and the telescopic rod 14 moves upward, driving the probe scanning frame 6 to move upward, so that the ultrasonic probe 9 moves upward. When needed, the pull rod can be pulled in the opposite direction. This design is a manual lifting detection mechanism 5, which can save the operating cost of the detection device to a certain extent.

[0052] In a preferred embodiment, the mobile trolley 1 is hinged to a slide rail 16, and a sliding block 17 is provided on the slide rail 16. The sliding block 17 is hinged to the probe scanning frame 6.

[0053] In the above embodiments, the design of the slide rail 16 and the sliding block 17 serves as a motion guide, enabling the probe scanning frame 6 to move up and down relatively stably.

[0054] In a preferred embodiment, the mobile trolley 1 is provided with a water tank 18, a water pump 19 and a water spray pipe 20 connected in sequence. The water pump 19 is electrically connected to the control component, and the free end of the water spray pipe 20 passes through the multi-channel probe frame 7 and is connected to a spray head 21.

[0055] In the above embodiment, the control component, i.e. the central processing unit, starts the water pump 19, which draws water from the water tank 18 and sprays it onto the surface of the object to be tested in front of the moving trolley 1 through the spray pipe 20 and the spray nozzle 21. This design enables the rapid application of the coupling agent and avoids the evaporation of water as the coupling agent when the weather is hot.

[0056] In a preferred embodiment, the mobile vehicle 1 is equipped with a monitoring camera 22 at its bottom and an edge sensor 23 on its side. Both the monitoring camera 22 and the edge sensor 23 are electrically connected to the control components.

[0057] In the above embodiment, the monitoring camera 22 allows personnel to clearly see whether the ultrasonic probe 9 at the bottom of the trolley is in contact with the surface of the object to be tested; the edge sensor 23 detects the edge position of the object, and when the edge position is reached, it can alert the personnel. Additionally, the mobile trolley 1 can be equipped with an alarm light connected to the central processing unit. When a defect is detected during the testing process, the alarm light activates to alert the personnel.

[0058] In a preferred embodiment, a placement plate 24 is slidably mounted on the mobile trolley 1, and the control components and the display 3 are mounted on the placement plate 24.

[0059] In the above embodiment, the mobile trolley 1 is provided with two lifting slide rails 16, and the placement plate 24 is placed on the sliders of the two lifting slide rails 16. The display 3 and the central processing unit are placed on the placement plate 24. The lifting slide rails 16 can be electrically controlled or manually controlled. This design allows personnel to adjust the height of the placement plate 24 according to their own height, making it convenient to view the detection data on the display 3.

[0060] In summary, the embodiments of this utility model provide a multi-directional floating ultrasonic testing device. The probe scanning frame 6 is hinged to the moving trolley 1, allowing the probe scanning frame 6 to swing back and forth. The probe scanning frame 6 is elastically connected to multiple probe clamps 8, allowing the probe clamps 8 to float up and down. The probe clamps 8 are hinged to the ultrasonic probe 9, allowing the ultrasonic probe 9 to swing left and right, thereby realizing the multi-directional movement of the ultrasonic probe 9. The floating ultrasonic probe is designed as a multi-directional adaptive floating structure, which allows the ultrasonic testing device to better match the uneven surface of the object to be inspected and is suitable for large-area objects such as steel plates.
