Description

Technical Field

[0001] This utility model relates to the field of radiation protection detection equipment technology, specifically a radiation protection ray detection device. Background Technology

[0002] In the field of industrial non-destructive testing (NDT), radiographic testing (RTT) is a core means of ensuring the quality and safety of metal components in machinery manufacturing, aerospace, automotive parts, and pressure vessels. It identifies internal and surface defects (such as cracks, pores, and inclusions) by utilizing the energy attenuation differences after X-rays penetrate the metal component. It is widely used in the factory inspection and in-service maintenance of critical components. However, existing RTT equipment generally adopts a "fixed-angle X-ray emission + workpiece stationary" inspection mode. The X-rays can only penetrate the workpiece from a single or a few fixed directions, resulting in natural blind spots in the inspection coverage. RTT cannot detect cracks nearly perpendicular to the X-rays because such cracks often cannot effectively block the X-rays. It also has relatively low sensitivity to micro-cracks, potentially failing to detect very small cracks or deformations. Inspection efficiency is low; the ionizing radiation characteristics of X-rays require significant additional time and cost for safety protection in existing inspection processes, leading to lengthy inspection cycles that are difficult to adapt to the pace of mass production lines. Therefore, a new RTT equipment is urgently needed to meet current usage requirements. Utility Model Content

[0003] This invention provides a radiation-proof X-ray inspection device that can solve the problems of existing inspection devices where the workpiece support platform is mostly a fixed structure, which cannot flexibly adjust the workpiece posture, and the X-rays can only cover a local area of ​​the workpiece, resulting in insufficient inspection coverage and some areas always being in the inspection blind zone, thus failing to detect workpiece defects.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a radiation protection detection device, comprising a base, with a first radiation protection shield and a second radiation protection shield fixedly installed at both ends of the upper side of the base, and a protective door provided between the first and second radiation protection shields; an X-ray source is disposed at the upper right end of the base, located inside the first radiation protection shield, and the X-ray source is horizontally arranged facing the second radiation protection shield; a receiving plate is correspondingly disposed at the upper left end of the base, and the receiving plate is vertically arranged; and a product placement platform is movably disposed between the X-ray source and the receiving plate. The bottom of the product placement stage is equipped with a hollow rotary platform, which can drive the product placement stage to rotate. The bottom of the hollow rotary platform is equipped with a linear module that drives its horizontal movement. The linear module is connected to the base and drives the hollow rotary platform, the product placement stage, and the workpiece to move left and right in the horizontal direction, adjusting the relative position of the workpiece with the X-ray source and the receiving plate to ensure that the X-ray can cover the workpiece. The hollow rotary platform connects the product placement stage and the linear module, which can drive the product placement stage and the workpiece to achieve 360° continuous rotation, so that the X-ray can penetrate the workpiece from multiple directions.

[0005] As a supplement to the technical solution described in this utility model, the upper part of the product placement table may optionally be provided with a heightening platform. The heightening platform is an optional accessory of the product placement table. By raising the workpiece, the detection height can be adjusted to accommodate workpieces of different heights and sizes, thus avoiding the situation where the X-ray only penetrates the edge of the workpiece due to insufficient workpiece height, which would affect the detection accuracy.

[0006] As a supplement to the technical solution described in this utility model, two slide rails are symmetrically arranged on the front and rear sides of the base along its length. The slider of the slide rail is connected to the protective door. The movement of the protective door is guided by the slide rail and the slider to ensure that its opening and closing are smooth and stable.

[0007] As a supplement to the technical solution described in this utility model, the first radiation shield and the second radiation shield have the same structure, both including an outer shell and a first radiation shield lead plate. The first radiation shield lead plate can prevent X-rays generated inside the equipment from penetrating the outer shell and scattering to the outside of the equipment, thus protecting the operators.

[0008] As a supplement to the technical solution described in this utility model, a second radiation-proof lead plate is provided on the inner side of the protective door. The second radiation-proof lead plate can prevent X-rays generated inside the equipment from penetrating the outer shell and scattering to the outside of the equipment, thus protecting the operators.

[0009] As a supplement to the technical solution described in this utility model, a mounting bracket is provided at the left end of the base, and a snap-fit ​​seat for securing the receiving plate is provided on the front side of the mounting bracket. The mounting bracket provides vertical mounting support for the receiving plate, and the snap-fit ​​seat accurately positions the receiving plate through a snap-fit ​​structure to ensure that the receiving plate is always in a vertical state.

[0010] As a supplement to the technical solution described in this utility model, the side of the X-ray source is provided with a fixed bracket connected to the base, and the fixed bracket is used to fix the X-ray source.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The linear module enables left-right translation of the workpiece, flexibly adjusting its relative position to the X-ray source and receiving plate. The hollow rotary platform rotates the product placement stage, allowing the metal workpiece to achieve multi-angle relative positions with the X-ray source. The X-rays can penetrate the workpiece from different directions, significantly improving the detection rate even for traditional "blind zone defects" such as transverse cracks and micropores. Furthermore, the optional height-adjustable platform allows the equipment to flexibly adapt to workpieces of varying heights, greatly expanding its application range. This solves the problems of existing inspection equipment where the workpiece support platform is mostly a fixed structure, unable to flexibly adjust the workpiece's posture, and the X-rays only covering a localized area of ​​the workpiece, resulting in insufficient detection coverage and some areas remaining in the detection blind zone, failing to detect workpiece defects.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] The embodiments of this utility model relate to a radiation protection ray detection device, such as... Figure 1-6As shown, the system includes a base 1, with a first radiation shield 2 and a second radiation shield 3 fixedly installed at both ends of the upper side of the base 1. The first radiation shield 2 and the second radiation shield 3 have the same structure, both including an outer shell 12 and a first radiation shield lead plate 13. The first radiation shield lead plate 13 is tightly fitted to the outer shell 12 to form a complete closed protective space. The outer shell 12 is made of 1.5mm thick cold-rolled steel plate with a rust-proof paint coating. The first radiation shield lead plate 13 is made of 99.9% pure industrial lead material with a thickness greater than 5mm. Plate 13 is fixed to the inside of the outer shell 12 with bolts. The joints are sealed with lead welding to prevent radiation leakage from the joint gaps. A third radiation-shielding lead plate is provided on the lower side of the base 1. The thickness of the third radiation-shielding lead plate is greater than 5mm. A protective door 6 is provided between the first radiation shield 2 and the second radiation shield 3. The protective door 6 is U-shaped. A connecting plate is welded to the bottom plate of the protective door 6. The connecting plate is connected to the slider of the slide rail 11 with bolts. A second radiation-shielding lead plate 14 is provided on the inside of the protective door 6. The second radiation-shielding lead plate 14 is made of 99% purity.Made of 9% industrial pure lead, with a thickness greater than 5mm, the second radiation shielding lead plate 14 is bolted to the inside of the protective door 6, and the joints are sealed using lead welding to prevent radiation leakage from the seams. The first radiation shielding lead plate 13, the second radiation shielding lead plate 14, and the third radiation shielding lead plate form a complete closed protective space, ensuring no blind spots after the equipment is closed, preventing X-rays generated inside the equipment from penetrating the outer shell and scattering to the outside, thus protecting the workers. An X-ray source 7 is located on the upper right side of the base 1 inside the first radiation shield 2. The X-ray source 7 is an externally purchased component; a 150kV microfocus X-ray source UNMS-U150B manufactured by Rilian Technology can be used as a reference. The X-ray source 7 is horizontally arranged facing the second radiation shield 3. A receiving plate 4 is correspondingly located on the upper left side of the base 1. The receiving plate 4 is vertically arranged and uses a flat panel detector with a pixel resolution of 1200×1. The X-ray source 7 (600) can convert the received X-ray signal into a digital image signal in real time and feed it back to an external display via a data transmission line. Workers can observe the internal structure of the metal workpiece on the display and accurately identify defects such as cracks, pores, and inclusions. The product placement stage 5 is movably positioned between the X-ray source 7 and the receiving plate 4. A hollow rotating platform 8 is located at the bottom of the product placement stage 5, which drives the stage to rotate. A linear module 9, connected to the base 1, drives the hollow rotating platform 8, the product placement stage 5, and the workpiece to move horizontally left and right, adjusting the relative position of the workpiece with the X-ray source 7 and the receiving plate 4 to ensure the X-rays cover the workpiece. The hollow rotating platform 8 connects the product placement stage 5 and the linear module 9, enabling the product placement stage 5 and the workpiece to rotate continuously 360°, allowing the X-rays to penetrate the workpiece from multiple directions.

[0023] In this embodiment, as Figure 2 As shown, the upper part of the product placement table 5 may optionally be provided with a heightening platform 10. The heightening platform 10 is an optional accessory of the product placement table 5. By raising the workpiece, the detection height can be adjusted to accommodate workpieces of different heights and sizes. For example, short workpieces need to be raised to align with the center of the X-ray, so as to avoid the X-ray only penetrating the edge of the workpiece due to insufficient workpiece height, which would affect the detection accuracy.

[0024] In this embodiment, as Figure 2 As shown, two slide rails 11 are symmetrically arranged on the front and rear sides of the base 1 along its length. The slider of the slide rail 11 is connected to the protective door 6. The slide rail 11 and the slider guide the movement of the protective door 6 to ensure that its opening and closing are smooth and stable.

[0025] In this embodiment, as Figure 2-3As shown, a mounting bracket 15 is provided at the left end of the base 1, and a snap-fit ​​seat 16 for snapping the receiving plate 4 is provided on the front side of the mounting bracket 15. The mounting bracket 15 provides vertical mounting support for the receiving plate 4, and the snap-fit ​​seat 16 accurately positions the receiving plate 4 through a snap-fit ​​structure to ensure that the receiving plate 4 is always in a vertical state.

[0026] In this embodiment, as Figure 2 As shown, the side of the X-ray source 7 is provided with a fixing bracket 17 connected to the base 1, and the fixing bracket 17 is used to fix the X-ray source 7.

[0027] In this embodiment, as Figure 1 As shown, the operator pulls the handle on the protective door 6, causing it to slide along the slide rail 11. Depending on the product height, the operator determines whether to use the riser platform 10, and then bonds and fixes the workpiece to the product placement table 5 or the riser platform 10. Alternatively, the workpiece clamp can be placed on the product placement table 5. The protective door 6 is then closed. A first lock body 18 is provided on the inner side of the protective door 6, and a second lock body 19 that cooperates with the first lock body 18 is provided on one side of the mounting bracket 15. When the first lock body 18 and the second lock body 19 are engaged, one end of the protective door 6 is located inside the first radiation shield 2, and the other end is located inside the second radiation shield 3. The protective door 6 and the first radiation shield 2... The second radiation shield 3 has no gaps at the joint. Clicking the start button on the control system's operating panel automatically executes the following linked actions: the hollow rotary platform 8 starts rotating at a preset speed (the hollow rotary platform 8 allows the workpiece to rotate continuously 360°, and the rotation speed can be adjusted within the range of 0.5°-5° / s to meet the angle control requirements of different testing scenarios); the linear module 9 synchronously drives the platform and workpiece to move horizontally, adjusting the workpiece's testing position; the X-ray source 7 emits rays, and the receiving plate 4 begins to receive the ray signals and convert them into digital images, which are transmitted to the display in real time. The operator observes the testing process through the display. After testing, the protective door 6 is opened, and the workpiece is removed. If the workpiece passes the test, a "Test Passed" label is affixed; if defects exist, the defect location is marked and the workpiece is isolated and stored.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
