Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to an X-ray nondestructive detector. Background Technology

[0002] Currently, pressure vessels on the market are generally formed by a tank body and end caps welded to its two openings. In order to ensure the sealing of the pressure vessel, X-ray non-destructive testing equipment is used to inspect the quality of the weld. However, when using existing weld X-ray non-destructive testing equipment, it is generally necessary to first inspect the weld on one side of the pressure vessel, and then move the equipment to the other side of the pressure vessel for inspection, which will make the inspection time longer and thus affect the work efficiency.

[0003] To address the aforementioned technical issues, a patent document with publication number (CN216771559U) discloses a weld X-ray non-destructive testing device, comprising components such as a mounting plate, a movable disc, a ring gear, a transmission gear, a fixing part, and an adjustment assembly. The front end of the mounting plate is rotatably connected to the movable disc, and the outer end of the movable disc is fixedly connected to the ring gear. The lower end of the ring gear meshes with the transmission gear. The lower edge of the rear end of the mounting plate is fixedly connected to the fixing part of a drive device. The movable part of the drive device passes through the mounting plate and is connected to the transmission gear. An adjustment assembly is provided at the front end of the movable disc, and a detection body for monitoring weld quality is mounted on the movable part of the adjustment assembly. By rotating the movable disc, the detection body rotates around the outer ring of the pressure vessel, enabling one-time inspection of the circular weld of the pressure vessel, improving work efficiency, and offering good applicability.

[0004] However, the height of the movable plate cannot be adjusted in the aforementioned existing technology, which makes it impossible to ensure that the detection body rotates around the axis of the pressure vessel, resulting in low practicality. Utility Model Content

[0005] The purpose of this invention is to provide an X-ray non-destructive detector, which aims to solve the technical problem in the prior art that the height of the movable disk cannot be adjusted, thus making it impossible to ensure that the detection body rotates around the axis of the pressure vessel, resulting in low practicality.

[0006] To achieve the above objectives, this utility model employs an X-ray non-destructive testing detector, comprising a base plate and a testing mechanism. The testing mechanism includes a frame, a bidirectional threaded rod, a first motor, two movable plates, two connecting rods, a support base, a second motor, a rotating disk, a detector body, a guide assembly, and an adjustment assembly. The frame is fixedly connected to the upper surface of the base plate. The bidirectional threaded rod passes through the two movable plates and is threadedly engaged with them. Both ends of the bidirectional threaded rod are rotatably connected to the frame. The output end of the first motor is fixedly connected to the bidirectional threaded rod. One end of each of the two connecting rods is hinged to one of the two movable plates, and the other end is hinged to the support base. The second motor is located on one side of the support base, and its output end passes through the support base and is fixedly connected to the rotating disk. The adjustment assembly is located on one side of the rotating disk. The detector body is fixedly connected to the adjustment assembly, and the guide assembly is located on one side of the support base.

[0007] The guide assembly includes a horizontal plate, two guide rods, and two limiting blocks. The horizontal plate is fixedly connected to one side of the support base. The two guide rods pass through the horizontal plate and are slidably connected to it. One end of each guide rod is fixedly connected to the base plate, and the other end of each guide rod is fixedly connected to the corresponding limiting block.

[0008] The adjusting assembly includes a slide rail, a sliding sleeve, a bolt, and a lifting component. The lifting component is disposed on one side of the rotating disk. The slide rail is fixedly connected to the lifting component. The sliding sleeve is sleeved on the outside of the slide rail and slidably connected to the slide rail. The bolt passes through the sliding sleeve and is threadedly connected to the sliding sleeve.

[0009] The lifting component includes a mounting frame, a lifting plate, two sliders, and a rotating component. The mounting frame is fixedly connected to one side of the rotating disk. The lifting plate is fixedly connected to the slide rail. One end of each of the two sliders is fixedly connected to the lifting plate. The other ends of each slider pass through the mounting frame and are slidably connected to the mounting frame. The rotating component is threadedly engaged with the lifting plate.

[0010] The rotating component includes a lead screw and a knob. The lead screw passes through the lifting plate and is threadedly engaged with the lifting plate. Both ends of the lead screw are rotatably connected to the mounting frame, and the knob is fixedly connected to one end of the lead screw.

[0011] This utility model discloses an X-ray non-destructive testing device. A bidirectional threaded rod passes through two movable plates and is threadedly engaged with each plate. The output end of a first motor is fixedly connected to the bidirectional threaded rod. One end of each of the two connecting rods is hinged to one of the movable plates, and the other end is hinged to a support base. The output end of a second motor passes through the support base and is fixedly connected to a rotating disk. In practical use, the base plate is moved to one side of the pressure vessel, and then the first motor is started. The output end of the first motor drives the bidirectional threaded rod to rotate, causing the two movable plates to move relative to each other. Each movable plate then drives one end of each connecting rod to move relative to the other end of the support base. The support moves upward, thereby adjusting the height of the rotating disk so that the axis of the rotating disk aligns with the axis of the pressure vessel. Then, the detector body is placed against the weld seam on one side of the pressure vessel. The second motor is then started, and its output drives the rotating disk to rotate, thereby rotating the detector body to inspect the weld seam. After inspection, the detector body is moved horizontally by the adjustment component to the weld seam on the other side of the pressure vessel. The second motor is then started again to inspect the weld seam on the other side. This method effectively solves the problem in the prior art where the height of the movable disk cannot be adjusted, thus preventing the detector body from rotating around the axis of the pressure vessel and resulting in low practicality.

[0020] This utility model provides an X-ray non-destructive testing detector, including a base plate 101 and a testing mechanism. The testing mechanism includes a frame 102, a bidirectional threaded rod 103, a first motor 104, two movable plates 105, two connecting rods 106, a support base 107, a second motor 108, a rotating disk 109, a detector body 110, a guide assembly, and an adjustment assembly. The guide assembly includes a horizontal plate 111, two guide rods 112, and two limiting blocks 113. The adjustment assembly includes a slide rail 114, a sliding sleeve 115, bolts 116, and a lifting component. The lifting component includes a mounting frame 117, a lifting plate 118, two sliders 119, and a rotating component. The rotating component includes a lead screw 120 and a knob 121. The aforementioned solution solves the problem in the prior art that the height of the movable disk cannot be adjusted, thus failing to ensure that the detection body rotates around the axis of the pressure vessel, resulting in low practicality.

[0021] In this specific embodiment, the frame 102 is fixedly connected to the upper surface of the base plate 101. The bidirectional threaded rod 103 passes through two movable plates 105 and is threadedly engaged with each of the two movable plates 105. Both ends of the bidirectional threaded rod 103 are rotatably connected to the frame 102. The output end of the first motor 104 is fixedly connected to the bidirectional threaded rod 103. One end of each of the two connecting rods 106 is hinged to one of the two movable plates 105, and the other end of each of the two connecting rods 106 is hinged to the support base 107. The second motor 108 is disposed on one side of the support base 107. The output end of the second motor 108 passes through the support base 107 and is fixedly connected to the rotating disk 109. The adjusting assembly is disposed on one side of the rotating disk 109. The detector body 110 is fixedly connected to the adjusting assembly. The guiding assembly is disposed on one side of the support base 107. In actual use, the base plate 101 is moved to one side of the pressure vessel. Then, the first motor 104 is started. The output end of the first motor 104 drives the bidirectional threaded rod 103 to rotate, causing the two moving plates 105 to move relative to each other. The two moving plates 105 respectively drive one end of the two connecting rods 106 to move relative to each other, and the other end of the two connecting rods 106 respectively drive the support base 107 to move upward, thereby adjusting the height of the rotating disk 109 so that the axis of the rotating disk 109 corresponds to the axis of the pressure vessel. Then, the detector body 110 is attached to the weld seam on one side of the pressure vessel. Then, the second motor 108 is started. The output end of the second motor 108 drives the rotating disk 109 to rotate, thereby driving the detector body 110 to rotate, thereby detecting the weld seam. After the detection is completed, the detector body 110 is moved horizontally by the adjustment component, thereby moving the detector body 110 to the weld seam on the other side of the pressure vessel. Then, the second motor 108 is started, thereby detecting the weld seam on the other side.

[0022] The horizontal plate 111 is fixedly connected to one side of the support base 107. Two guide rods 112 pass through the horizontal plate 111 and are slidably connected to it. One end of each guide rod 112 is fixedly connected to the base plate 101, and the other end is fixedly connected to the corresponding limiting block 113. In actual use, the support base 107 moves up and down, causing the horizontal plate 111 to slide on the two guide rods 112, thereby guiding the support base 107. The two limiting blocks 113 limit the horizontal plate 111.

[0023] Secondly, the lifting component is disposed on one side of the rotating disk 109, the slide rail 114 is fixedly connected to the lifting component, the sliding sleeve 115 is sleeved on the outside of the slide rail 114 and slidably connected to the slide rail 114, and the bolt 116 passes through the sliding sleeve 115 and is threadedly connected to the sliding sleeve 115. In actual use, the rotation radius of the slide rail 114 is adjusted by the lifting component, thereby adjusting the rotation radius of the detector body 110. By sliding the sliding sleeve 115, the horizontal position of the detector body 110 can be adjusted. By tightening the bolt 116, the bolt 116 abuts against the slide rail 114, thereby fixing the sliding sleeve 115 to the slide rail 114.

[0024] Meanwhile, the mounting frame 117 is fixedly connected to one side of the rotating disk 109, the lifting plate 118 is fixedly connected to the slide rail 114, one end of each of the two sliders 119 is fixedly connected to the lifting plate 118, and the other ends of each of the two sliders 119 pass through the mounting frame 117 and are slidably connected to the mounting frame 117. The rotating component is threadedly engaged with the lifting plate 118. In actual use, rotating the rotating component causes the lifting plate 118 to slide within the mounting frame 117. The lifting plate 118 drives the two sliders 119 to slide on the mounting frame 117, and at the same time, the lifting plate 118 drives the slide rail 114 to move.

[0025] In addition, the lead screw 120 passes through the lifting plate 118 and is threadedly engaged with the lifting plate 118. Both ends of the lead screw 120 are rotatably connected to the mounting frame 117. The knob 121 is fixedly connected to one end of the lead screw 120. In actual use, rotating the knob 121 causes the lead screw 120 to rotate, so that the lifting plate 118 slides within the mounting frame 117.

[0026] In the specific use of an X-ray non-destructive detector according to this embodiment, the base plate 101 is moved to one side of the pressure vessel, and then the first motor 104 is started. The output end of the first motor 104 drives the bidirectional threaded rod 103 to rotate, causing the two moving plates 105 to move relative to each other. The two moving plates 105 respectively drive one end of the two connecting rods 106 to move relative to each other, and the other ends of the two connecting rods 106 respectively drive the support base 107 to move upward, thereby adjusting the height of the rotating disk 109 so that the axis of the rotating disk 109 corresponds to the axis of the pressure vessel. Then, the knob 121 is rotated, and the knob 121 drives the lead screw 120 to rotate, causing the lifting plate 118 to slide within the mounting frame 117. The lifting plate 118 drives the slide rail 114 to slide, so that the detector body 11... The detector body 110 is then activated by first fitting the detector body 109 against the outer wall of the pressure vessel. The output of the second motor 108 drives the rotating disk 109 to rotate, which in turn drives the detector body 110 to rotate, thus inspecting the weld. After inspection, the sliding sleeve 115 is slid on the slide rail 114, thereby moving the detector body 110 horizontally so that it fits against the weld on the other side of the pressure vessel. Then, the bolt 116 is tightened, causing it to abut against the slide rail 114, thus fixing the sliding sleeve 115 to the slide rail 114. The second motor 108 is then activated to inspect the weld on the other side. This method effectively solves the problem in the prior art where the height of the movable disk cannot be adjusted, thus preventing the detector body from rotating around the axis of the pressure vessel, resulting in low practicality.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
