Description

Technical Field

[0001] This application relates to the field of flaw detection technology, and in particular to a flaw detection device for weld seams of large amusement facilities. Background Technology

[0002] Detection methods are used to inspect for cracks or defects inside metallic materials or components. Commonly used methods include X-ray inspection, ultrasonic testing, magnetic particle inspection, penetrant testing, eddy current testing, and gamma-ray inspection. Physical testing is non-destructive testing performed without causing chemical changes.

[0003] The large amusement facility weld flaw detection device mentioned in the existing Chinese patent (authorization announcement number: CN215609110U) can improve the stability of the equipment by using two clamping mechanisms to hold the equipment and prevent the equipment from tilting. The rotating mechanism can drive the two sleeves to rotate, and the sleeves can drive the clamped equipment to rotate. This allows the circumferential weld to be detected by an ultrasonic generator. The position of the clamped equipment can also be changed by the screw slide, ensuring the comprehensiveness of the flaw detection of the clamped equipment and improving the quality of the flaw detection.

[0004] Currently, when inspecting welds on amusement rides, most methods involve simply placing the ride on a fixed pulley. While this is simple and easy, amusement rides are mostly stored in the external environment, where dust and debris can affect the contact between the inspection equipment and the ride's surface, thus impacting the accuracy of the inspection results. This requires manual cleaning by staff, which is inconvenient. Utility Model Content

[0005] The purpose of this application is to address the problem that dust and debris in the external environment may affect the contact between the testing equipment and the surface of the amusement facility, thereby affecting the accuracy of the testing results. This application provides a weld flaw detection device for large amusement facilities.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A flaw detection device for weld seams of large amusement facilities includes a workbench, with support rollers symmetrically installed on the top of the workbench, a hydraulic telescopic rod fixedly connected to the top of the workbench, a top plate fixedly connected to the top of the hydraulic telescopic rod, an ultrasonic flaw detector installed on the top of the top plate, a detection probe installed at the bottom of the top plate, the detection probe being electrically connected to the ultrasonic flaw detector, and a cleaning mechanism provided on the top of the workbench.

[0008] By adopting the above technical solution, the amusement ride is placed on the placement roller, then the placement roller is rotated to drive the amusement ride to rotate. Then, the hydraulic telescopic rod is activated, and the height of the top plate is adjusted according to the height of the amusement ride to keep the detection probe at a suitable distance and angle from the weld surface of the amusement ride. The ultrasonic flaw detector is turned on, and the presence of defects such as cracks, pores, and slag inclusions in the weld is determined based on the waveform and data displayed by the ultrasonic flaw detector. The surface of the amusement ride can be cleaned by the cleaning mechanism, reducing the inconvenience of manual cleaning.

[0009] Furthermore, the cleaning mechanism includes electrically telescopic rods symmetrically and fixedly connected to the top of the workbench, with a movable plate fixedly connected to the top of the electrically telescopic rods, and a cleaning block fixedly connected to the outer side of the movable plate.

[0010] By adopting the above technical solution, the electric telescopic rod is activated to drive the moving plate to move, the moving plate to drive the cleaning block to move, the cleaning block to move and come into contact with the outside of the amusement facility, and then the placement roller is rotated to drive the amusement facility to rotate, thereby cleaning the outside of the amusement facility.

[0014] By adopting the above technical solution, the top of the collection bin is made open, allowing the garbage to fall into the collection bin and be stored.

[0015] Furthermore, the outer side of the collection box is symmetrically and fixedly connected with a limiting block, and the outer side of the workbench is symmetrically and fixedly connected with a limiting frame. The limiting frame and the limiting block are slidably arranged. A slot is opened on the inner side of the limiting block. A spring is fixedly connected to the inner side of the slot. A moving block is fixedly connected to one end of the spring. A locking block is fixedly connected to the bottom of the moving block. The locking block abuts against the limiting block.

[0016] By adopting the above technical solution, the elastic potential energy is used to make the locking block resist the limiting block, thus ensuring the stability of the collection box during the collection process.

[0017] Furthermore, the top of the limiting block is provided with a locking groove, and both the locking block and the locking groove are set to be hemispherical, and the locking block and the locking groove are engaged and connected.

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] This application discloses a flaw detection device for weld seams of large amusement facilities.

[0035] Reference Figure 1 and Figure 2 A large amusement facility weld flaw detection device includes a workbench 1, with support rollers 2 symmetrically installed on the top of the workbench 1, a hydraulic telescopic rod 3 fixedly connected to the top of the workbench 1, a top plate 4 fixedly connected to the top of the hydraulic telescopic rod 3, an ultrasonic flaw detector 5 installed on the top of the top plate 4, a detection probe 6 installed at the bottom of the top plate 4, the detection probe 6 being electrically connected to the ultrasonic flaw detector 5, and a cleaning mechanism provided on the top of the workbench 1.

[0036] When inspecting the welds of amusement rides, the ride is first placed on the placement rollers. Then, the placement rollers are rotated to make the ride rotate. Next, the hydraulic telescopic rod 3 is activated, and the height of the top plate 4 is adjusted according to the height of the ride to ensure that the detection probe 6 maintains a suitable distance and angle with the weld surface of the ride. The ultrasonic flaw detector 5 is then turned on, and the detection probe 6 emits ultrasonic waves to conduct a comprehensive inspection of the weld. During the inspection, the ultrasonic flaw detector 5 receives the reflected ultrasonic signals and converts them into electrical signals. Based on the waveform and data displayed by the ultrasonic flaw detector 5, it is determined whether there are defects such as cracks, porosity, and slag inclusions in the weld. The surface of the ride can be cleaned by the cleaning mechanism, reducing the inconvenience of manual cleaning.

[0037] Reference Figure 2 and Figure 3The cleaning mechanism includes an electric telescopic rod 7 that is symmetrically and fixedly connected to the top of the workbench 1. A movable plate 8 is fixedly connected to the top of the electric telescopic rod 7, and a cleaning block 9 is fixedly connected to the outside of the movable plate 8.

[0038] In addition, a connecting block 10 is fixedly connected to the outer side of the movable plate 8, and a guide rod 11 is fixedly connected to the top of the worktable 1. The top end of the guide rod 11 passes through the connecting block 10, and the guide rod 11 is slidably connected to the connecting block 10.

[0039] When cleaning amusement facilities, the electric telescopic rod 7 is first activated to move the moving plate 8. The moving plate 8 moves the cleaning block 9. The cleaning block 9 moves and comes into contact with the outside of the amusement facility. Then, the placement roller is rotated to make the amusement facility rotate, thereby cleaning the outside of the amusement facility. This reduces the inconvenience of manual cleaning, reduces labor intensity, and improves the efficiency of cleaning work.

[0040] When the movable plate 8 moves, the connecting block 10 and the guide rod 11 provide additional support points for the movable plate 8, so that the movable plate 8 can remain stable when moving.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The top of the workbench 1 is provided with a collection hole 12, and the outer side of the workbench 1 is provided with a collection groove 13. A collection box 14 is slidably connected to the inner side of the collection groove 13. The top of the collection box 14 is set to be open. The opening of the collection box 14 is adapted to the collection hole 12. A handle 15 is fixedly connected to the outer side of the collection box 14.

[0042] When collecting the cleaned garbage, the garbage scraped off by the cleaning block 9 will fall into the collection hole 12. The garbage in the collection hole 12 will continue to fall downwards under the action of gravity. The top of the collection box 14 is set to be open, so the garbage falls into the collection box 14 and is stored. When a certain amount has been stored, the staff can pull the handle 15 to take out the collection box 14 for cleaning, thereby reducing the risk of garbage falling onto the workbench 1 and ensuring the cleanliness of the working environment.

[0043] Reference Figure 4 and Figure 5 The outer side of the collection box 14 is symmetrically and fixedly connected to the limiting block 16, and the outer side of the worktable 1 is symmetrically and fixedly connected to the limiting frame 17. The limiting frame 17 and the limiting block 16 are slidably arranged. The inner side of the limiting block 16 is provided with a slot 18. A spring 19 is fixedly connected to the inner side of the slot 18. One end of the spring 19 is fixedly connected to a moving block 20. The bottom of the moving block 20 is fixedly connected to a locking block 21. The locking block 21 abuts against the limiting block 16.

[0044] The top of the limiting block 16 is provided with a locking groove 22. Both the locking block 21 and the locking groove 22 are set as hemispherical, and the locking block 21 and the locking groove 22 are locked together.

[0045] In addition, the inner side of the empty slot 18 is symmetrically provided with a sliding groove 23, and the outer side of the moving block 20 is symmetrically fixedly connected with a slider, which is slidably connected to the sliding groove 23.

[0046] When the collection box 14 is fixed, the collection box 14 moves the limiting block 16 into the limiting frame 17. At this time, the locking block 21 will abut against the limiting block 16, causing the locking block 21 to move upward. The upward movement of the locking block 21 drives the moving block 20 upward, and the upward movement of the moving block 20 will squeeze the spring 19, causing the spring 19 to compress and generate elastic potential energy. Through the elastic potential energy, the locking block 21 abuts against the limiting block 16. When the locking block 21 moves to the position of the locking groove 22, the locking block 21 engages with the locking groove 22 to limit the limiting block 16, ensuring the stability of the collection box 14 during the collection process.

[0047] When the collection box 14 needs to be removed, both the locking block 21 and the locking groove 22 are set to be hemispherical. Under the sliding action of the arc surface, the locking block 21 moves inside the locking groove 22, thereby causing the locking block 21 to disengage from the locking groove 22.

[0048] When the moving block 20 moves, the slider and the groove 23 provide guidance for the moving block 20, so that the moving block 20 maintains the correct movement trajectory when moving.

[0049] Reference Figure 1 and Figure 2 The bottom of the top plate 4 is fixedly connected to a guide rod 24, and the outside of the hydraulic telescopic rod 3 is fixedly connected to a connecting block 25. One end of the guide rod 24 passes through the connecting block 25, and the connecting block 25 is slidably connected to the guide rod 24.

[0050] When the top plate 4 moves, the connecting block 25 and the guide rod 24 provide a clear guiding path for the top plate 4, enabling the top plate 4 to rise or fall smoothly along the direction of the guide rod 24.

[0051] Working principle: The amusement ride is placed on the placement roller, and then the placement roller is rotated to make the amusement ride rotate. Then, the hydraulic telescopic rod 3 is activated, and the height of the top plate 4 is adjusted according to the height of the amusement ride to make the detection probe 6 maintain a suitable distance and angle with the weld surface of the amusement ride. The ultrasonic flaw detector 5 is turned on, and the detection probe 6 emits ultrasonic waves to conduct a comprehensive inspection of the weld. According to the waveform and data displayed by the ultrasonic flaw detector 5, it is determined whether there are defects such as cracks, pores, and slag inclusions in the weld. The electric telescopic rod 7 is activated to move the moving plate 8. The movement of the moving plate 8 moves the cleaning block 9. The cleaning block 9 will come into contact with the outside of the amusement ride. Then, the placement roller is rotated to make the amusement ride rotate, thereby cleaning the outside of the amusement ride.
