Description

Technical Field

[0001] This utility model relates to the field of fixed support technology, and in particular to a portable fixed support for a radiographic flaw detector. Background Technology

[0002] The mounting bracket of a radiographic flaw detector is typically used to support and fix the flaw detection instrument, ensuring its stability during radiographic testing and guaranteeing accurate detection. The mounting bracket is an important component of the radiographic flaw detector system, providing necessary support, stability, and precise positioning to ensure the smooth operation of radiographic flaw detection.

[0003] In traditional X-ray flaw detectors, the mounting brackets are mostly designed with a fixed or integrated assembly structure. This structure typically fixes various components together using welding, bolts, or other methods to form a single frame. Because this type of bracket design is usually pre-shaped, it cannot be height-adjusted or flexibly adjusted in angle. Therefore, it is limited in practical applications, which can affect the accurate positioning of the X-ray source and consequently the flaw detection results. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable mounting bracket for a radiographic flaw detector, aiming to improve the problem that the mounting brackets of radiographic flaw detectors in traditional technologies are mostly designed with fixed or integrated assembly structures, resulting in insufficient accuracy of the X-ray source and reduced flaw detection effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable mounting bracket for a radiographic flaw detector, comprising a base, a support rod fixedly connected to the top of the base, an adjusting sleeve slidably connected to the outside of the support rod, a connecting rod fixedly connected to the outside of the adjusting sleeve, a robotic arm rotatably connected to the side of the connecting rod away from the adjusting sleeve, a U-shaped frame rotatably connected to the side of the robotic arm away from the connecting rod, an adjusting disc rotatably connected to the side of the U-shaped frame away from the robotic arm, a flaw detector fixedly connected to the side of the adjusting disc away from the U-shaped frame, a lifting mechanism provided outside the adjusting sleeve for adjusting the height of the adjusting sleeve, and a locking mechanism provided outside the adjusting disc for fixing the rotation angle of the adjusting disc;

[0006] The lifting mechanism includes a mounting shell, which is fixedly connected to the outside of the adjusting sleeve. A spring is fixedly connected inside the mounting shell. A limit block is fixedly connected to the side of the spring near the adjusting sleeve. A pin is fixedly connected inside the limit block. Several slots are provided on the outside of the support rod.

[0007] As a further description of the above technical solution:

[0008] The pin passes through the outside of the adjusting sleeve and engages with the slot.

[0009] As a further description of the above technical solution:

[0010] A fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected inside the fixing box, a baffle plate is fixedly connected to the bottom of the sliding plate, and the bottom of the baffle plate abuts against the top of the limiting block.

[0011] As a further description of the above technical solution:

[0012] The limiting block is slidably connected inside the mounting housing, and the pin passes through both ends of the mounting housing.

[0013] As a further description of the above technical solution:

[0014] A handle is fixedly connected to the side of the pin away from the limiting block.

[0015] As a further description of the above technical solution:

[0016] The locking mechanism includes a gear ring, which is fixedly connected to the outside of the adjusting disc. Two connecting brackets are fixedly connected to the outside of the adjusting disc. A rotating shaft is rotatably connected inside each of the two connecting brackets, and two locking teeth are fixedly connected to the outside of each of the two rotating shafts.

[0017] As a further description of the above technical solution:

[0018] A torsion spring is provided on the outside of the rotating shaft. One end of the torsion spring is fixedly connected to the inside of the connecting frame, and the other end of the torsion spring is fixedly connected to the outside of the rotating shaft.

[0019] As a further description of the above technical solution:

[0020] One of the teeth engages with the gear ring.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the height of the connecting rod needs to be adjusted, the pin is pulled out from the slot by the handle, causing the limiting block to compress the spring and retract into the mounting shell. When the limiting block moves, the baffle plate automatically falls and blocks the limiting block due to gravity. After adjusting the height of the adjusting sleeve, the baffle plate is pulled up by the sliding plate. At this time, the spring rebound force pushes the limiting block and drives the pin to move forward, passing through the adjusting sleeve and re-engaging with the slot. This achieves the effect of flexibly adjusting the height of the flaw detector through the lifting mechanism, allowing the device to be appropriately extended, improving the positioning accuracy of the X-ray source, and improving the practicality of the device.

[0023] 2. In this utility model, when rotating the flaw detector, the locking teeth are released from their engagement with the gear ring by turning the locking teeth. At this time, the angle of the flaw detector can be adjusted by rotating the adjustment disc. After the angle is determined, the locking teeth are released. Under the influence of the torsion spring, the locking teeth on the other side will automatically reset and engage with the gear ring to fix it. This achieves the effect of quickly adjusting the angle of the flaw detector through the locking mechanism, so that the device can perform radiographic flaw detection from multiple angles, thus improving the practicality of the device.

A support rod 2 is fixedly connected to the top of the base 1, and the support rod 2 connects to an adjusting sleeve 3. An adjusting sleeve 3 is slidably connected to the outside of the support rod 2, and the adjusting sleeve 3 is used to install a connecting rod 4. A connecting rod 4 is fixedly connected to the outside of the adjusting sleeve 3, and the connecting rod 4 connects to a robotic arm 5. The robotic arm 5 is rotatably connected to the side of the connecting rod 4 away from the adjusting sleeve 3, and the robotic arm 5 connects to a U-shaped frame 6. The U-shaped frame 6 is rotatably connected to the side of the robotic arm 5 away from the connecting rod 4, and the U-shaped frame 6 connects to an adjusting disc 7. The adjusting disc 7 is rotatably connected to the side of the U-shaped frame 6 away from the robotic arm 5, and the adjusting disc 7 connects to a flaw detector 8. The flaw detector 8 is fixedly connected to the side of the adjusting disc 7 away from the U-shaped frame 6. A lifting mechanism is provided on the outside of the adjusting sleeve 3 for adjusting the height of the adjusting sleeve 3. A locking mechanism is provided on the outside of the adjusting disc 7 for fixing the rotation angle of the adjusting disc 7.

[0033] The lifting mechanism includes a mounting shell 9, which serves to fix the internal structure. The mounting shell 9 is fixedly connected to the outside of the adjusting sleeve 3. A spring 10 is fixedly connected inside the mounting shell 9. The spring 10 provides elastic force to push the limiting block 11. The limiting block 11 is fixedly connected to the side of the spring 10 near the adjusting sleeve 3. The limiting block 11 prevents the spring 10 from falling off. A pin 12 is fixedly connected inside the limiting block 11. The pin 12 is used for locking and fixing. Several slots 22 are opened on the outside of the support rod 2. The slots 22 are used for locking and fixing. The pin 12 passes through the outside of the adjusting sleeve 3 and engages with the slot 22. The top of the mounting shell 9 is fixedly connected to the fixing box 13, which serves to fix the internal structure. The inside of the fixing box 13 is slidably connected to the slide plate 14, which serves to connect the baffle plate 15. The bottom of the slide plate 14 is fixedly connected to the baffle plate 15, which serves to restrict the movement of the limiting block 11. The bottom of the baffle plate 15 abuts against the top of the limiting block 11. The limiting block 11 is slidably connected inside the mounting shell 9. The pin 12 passes through both ends of the mounting shell 9. The side of the pin 12 away from the limiting block 11 is fixedly connected to the handle 16.

[0034] Specifically, height adjustment is achieved by using the pin 12 inside the mounting housing 9 in conjunction with the limit block 11 and the spring 10, and by engaging the pin 12 with the slot 22.

[0035] Reference Figure 1 and Figure 4 - Figure 5The locking mechanism includes a gear ring 17, which engages and is fixedly connected to the outside of the adjusting disc 7. Two connecting brackets 18 are fixedly connected to the outside of the adjusting disc 7, connecting the rotating shaft 19. The rotating shaft 19 is rotatably connected inside each of the two connecting brackets 18, and it connects to locking teeth 20. Two locking teeth 20 are fixedly connected to the outside of each of the two rotating shafts 19, engaging with each other. A torsion spring 21 is provided on the outside of the rotating shaft 19, providing torque to push the locking teeth 20 back. One end of the torsion spring 21 is fixedly connected to the inside of the connecting bracket 18, and the other end is fixedly connected to the outside of the rotating shaft 19. One of the locking teeth 20 engages with the gear ring 17.

[0036] Specifically, the angle of the flaw detector 8 can be adjusted by rotating the adjustment disc 7 by moving the toothed 20.

[0037] Working principle: When the height of the connecting rod 4 needs to be adjusted, the pin 12 is pulled out from the slot 22 by the handle 16, which causes the limiting block 11 to compress the spring 10 and retract into the mounting shell 9. When the limiting block 11 moves, the baffle plate 15 automatically falls down due to gravity to block the limiting block 11. After the height of the adjusting sleeve 3 is adjusted, the baffle plate 15 is pulled up by the slide plate 14. At this time, the limiting block 11 is pushed by the spring 10 to drive the pin 12 to move forward, pass through the adjusting sleeve 3 and re-engage with the slot 22 to fix it.

[0038] When rotating the flaw detector 8, release the locking tooth 20 from the gear ring 17 by turning the locking tooth 20. At this time, the angle of the flaw detector 8 can be adjusted by rotating the adjustment disc 7. After determining the angle, release the locking tooth 20. Under the influence of the torque of the torsion spring 21, the locking tooth 20 on the other side will automatically reset and lock into the gear ring 17.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
