Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, specifically to an X-ray surround metal nondestructive testing device. Background Technology

[0002] X-ray surround metal non-destructive testing equipment is a high-tech instrument that uses X-rays to detect internal defects in metallic materials. It works on the principle that X-rays can penetrate metal and form images of different densities on film due to differences in material absorption and scattering. This equipment can accurately and reliably detect the shape, location, and size of internal defects in materials non-destructively, and can also determine the thickness of materials. As one of the commonly used flaw detection equipment, X-ray surround metal non-destructive testing equipment is widely used in flaw detection and testing of components such as industrial pipelines to ensure product quality and safety.

[0003] Chinese patent CN218382480U discloses a surround-type X-ray non-destructive testing device. By adjusting the drive mechanism, the adjustment wheel group and screw are driven to rotate synchronously. The screw drives the nut pair to gradually move towards the pipeline axis. The first movable frame drives the pressure wheel assembly to move together until the pressure wheel of the pressure wheel assembly presses the pipeline. This can realize the rapid positioning of the device, save time and effort, and ensure the detection accuracy.

[0004] The aforementioned patented non-destructive testing device uses a transmission belt, adjusting wheel set, first driving bevel gear and first driven bevel gear for transmission during testing to achieve adaptation and rotation. The entire transmission structure is relatively complex, with low stability and service life, and is difficult to maintain. The maintenance frequency needs to be increased due to the complexity of the structure. Utility Model Content

[0005] The purpose of this invention is to provide an X-ray surround metal non-destructive testing device. The first threaded rods on both sides of the movable frame can rotate and actively move towards the center of the pipe to be tested, which can directly adapt to the pipe diameter. With the support of the base, the X-ray source can be directly driven to rotate after the gear rotates. The entire transmission structure is efficient and fast, and can adapt to the testing of pipes of different sizes. It eliminates multiple unnecessary transmission structures, reduces the number of subsequent maintenance locations and the frequency of maintenance, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An X-ray surround metal non-destructive testing device includes a base, a first support at the upper end of the base, movable frames at both the upper and lower ends of the first support, threaded rods with threaded engagement on both sides of the first support, rollers with mounting columns on the outer side of each movable frame facing the first support, and mounting holes evenly distributed laterally inside the movable frames for connecting with external slots of the mounting columns, a transmission ring fixed by welding to the rear end of the first support via a connecting block, and a movable rail at the rear end of the transmission ring, with the base slidingly embedded into both sides of the movable rail. After being supported by the base, the transmission ring rotates, and the base slides into the movable rail, facilitating the rotation of an X-ray source with a front-end adapted to the pipe diameter.

[0008] Preferably, a gear is provided on one side of the upper end of the base, and the outer wall of the transmission ring is surrounded by a toothed groove that meshes with the gear. When the transmission ring needs to rotate and drive the X-ray source at the front end to rotate, the rotation of the gear can drive the transmission ring to rotate through the meshing connection, and can complete the detection of the corresponding position around the pipe.

[0009] Preferably, the upper end of the mounting post is provided with a threaded nut. When adjusting the lateral position of the roller, after the mounting post slides into the mounting hole, the nut rotates outside the mounting post to fix the roller after adjusting its position.

[0010] Preferably, a transmission block is welded to the upper end of each of the two first threaded rods, and the two transmission blocks are connected by a transmission belt. Through the connection of the transmission blocks and the transmission of the transmission belt, the two first threaded rods can be rotated simultaneously after the motor is driven.

[0011] Preferably, a second support is provided at the front end of the first support, and a second threaded rod is rotatably provided at the upper middle part of the first support. The second threaded rod passes through and extends to the upper and lower ends of the second support. The second support and the second threaded rod are threadedly engaged at the through position. The horizontal position of the X-ray source can be adjusted longitudinally by rotating the second threaded rod, which can further adapt to pipes of different sizes to be inspected.

[0012] Preferably, the outer wall of the second bracket is provided with an X-ray source that is fixed by bolts. The fixing by bolts facilitates subsequent maintenance and disassembly and assembly of the equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When adapting to the diameter of the pipe to be inspected, this utility model, through the transmission block and transmission belt, can simultaneously rotate the first threaded rod after being driven by the motor. The rotation of the first threaded rod on both sides of the movable frame can actively move towards the center position of the pipe to be inspected, which can directly adapt to the pipe diameter. After adaptation, with the support of the base, the first bracket can be driven by the gear to rotate outside the pipe. It can efficiently adapt to pipes of different diameters. With the support of the base, the rotation of the gear can directly drive the rotation of the X-ray source. The entire transmission structure is efficient and fast, can adapt to the inspection of pipes of different sizes, eliminates multiple unnecessary transmission structures, reduces subsequent maintenance positions and maintenance frequency, and enables the equipment to cope with harsh and complex environments.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] like Figure 1As shown, an X-ray surround metal non-destructive testing device according to this embodiment includes a base 1, a first support 2 is provided at the upper end of the base 1, and movable frames 4 are provided at both the upper and lower ends inside the first support 2. First threaded rods 3 are vertically provided on both sides inside the first support 2, and the outer sides of the first threaded rods 3 penetrate and extend to both sides of the movable frames 4. The outer side of the first threaded rods 3 is threadedly engaged with the through position of the movable frames 4. By rotating the first threaded rods 3, the movable frames 4 can be adjusted longitudinally and horizontally after rotation. The movable frames 4 can actively move longitudinally toward the outer wall of the pipe to adapt to pipes of different diameters.

[0025] Furthermore, both movable frames 4 have rollers 5 on the side facing the first support 2. The upper end of the rollers 5 is provided with a mounting post 8, and the mounting post 8 is rotatably connected to the rollers 5. The rollers 5 can be easily supported by the mounting post 8, so that the rollers 5 can clamp and fit against the outer wall of the pipe to be tested.

[0026] To further adapt to pipes of different sizes and diameters to be inspected, the movable frame 4 has horizontally evenly distributed mounting holes 6 inside, and the inside of the mounting holes 6 is connected to the external slot of the mounting column 8. When fixed, the mounting column 8 can slide into the mounting hole 6 and pass through the movable frame 4. A nut 7 is provided at the upper end of the outside of the mounting column 8, and the inside of the nut 7 is engaged with the external thread of the mounting column 8. After the mounting column 8 slides into the mounting hole 6, the rotation of the nut 7 can fix the position of the roller 5, thus completing the adaptation of the pipe size to be inspected.

[0027] It is worth mentioning that, in order to enable the first threaded rods 3 on both sides to perform unified transmission and to make stable longitudinal horizontal position adjustment of the movable frame 4, a transmission block 16 is provided at the upper end of each of the two first threaded rods 3, and the transmission block 16 is welded and fixed to the first threaded rod 3. The two transmission blocks 16 are connected by a transmission belt 17. A motor is provided at the lower end of one of the first threaded rods 3. The output of the motor can drive the first threaded rod 3 to rotate. After one of the first threaded rods 3 rotates, it can drive both first threaded rods 3 to rotate simultaneously through the transmission block 16 and the transmission belt 17.

[0028] The first support 2 has a second support 10 at its front end. A second threaded rod 9 is vertically installed at the upper middle part of the first support 2, and a motor is installed at one end of the second threaded rod 9. The two ends of the second threaded rod 9 are rotatably connected to the interior of the first support 2. The second threaded rod 9 passes through and extends to the upper and lower ends of the second support 10. The second support 10 and the second threaded rod 9 are threadedly engaged at the through position. After the motor drives the second threaded rod 9, the rotation of the second threaded rod 9 can drive the second support 10 to adjust its horizontal position. While adapting to the outer wall of the pipe to be inspected, the horizontal position of the X-ray source 11 can be adjusted to adapt to the shape of the pipe outer wall. The outer wall of the second support 10 is provided with the X-ray source 11, and the outer wall of the X-ray source 11 is fixedly connected to the second support 10 by bolts. The position of the X-ray source 11 can be further adjusted by the rotation of the second threaded rod 9 and the adaptation of the first support 2.

[0029] To facilitate the driving of the X-ray source 11 and to make the X-ray source 11 rotate along the outer wall of the clamped pipe, a transmission ring 13 is provided at the rear end of the first support 2. The transmission ring 13 is welded and fixed to the first support 2 by a connecting block 12. A movable rail 14 is provided at the rear end of the transmission ring 13. The base 1 is slidably embedded in both sides of the movable rail 14. The rotation of the transmission ring 13 can drive the X-ray source 11 at the front end to rotate.

[0030] In addition, a gear 15 is provided on one side of the upper end of the base 1, and a toothed groove that meshes with the gear 15 is provided around the outer wall of the transmission ring 13. A motor is provided at one end of the center of the gear 15, and the motor can be started by the gear 15 driving the transmission ring 13 to rotate.

[0031] Working principle: The device is used to detect damage to the outer wall of the pipe. Based on the pipe diameter, the mounting post 8 is inserted into the corresponding mounting hole 6. The nut 7 is rotated outside the mounting post 8, and after rotating and fitting against the upper end of the movable frame 4, the roller 5 is fixed. Driven by a motor at one end of the first threaded rod 3 via the transmission belt 17, both first threaded rods 3 rotate simultaneously and move relative to the two ends of the movable frame 4. The distance between the two movable frames 4 can be adjusted longitudinally by the constraint of the first bracket 2, allowing for fitting and clamping of the pipe. The motor drives the second threaded rod 9 to rotate, and the rotation of the second threaded rod 9 is related to the rotation of the first threaded rod 4. The two supports 10 generate relative motion. After being restricted by the first support 2, the second support 10 changes from rotational motion to longitudinal linear motion. The longitudinal horizontal position of the second support 10 adjusts the horizontal position of the X-ray source 11, which can adjust the lower detection position of the X-ray source 11 to be closer to the outer wall of the pipe. The gear 15 rotates after being driven. The gear 15 drives the transmission ring 13 to rotate through meshing connection. The rotation of the transmission ring 13 can drive the first support 2, the movable frame 4 and the roller 5 to rotate through the connecting block 12. During the rotation of the roller 5, the X-ray source 11 can surround the pipe and detect the outer wall of the pipe to perform pipe detection.
