Description

Technical Field

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

[0002] X-ray destructive testing is a non-destructive testing method that utilizes the properties of X-rays to penetrate and attenuate within materials to detect defects. It can detect internal defects in both metallic and non-metallic materials. However, X-ray destructive testing involves radiation exposure, requiring protective devices to shield against it. But conventional protective devices have some drawbacks, such as:

[0003] Typical X-ray flaw detectors are placed in a separate space, with the interior and exterior connected by a door. The gaps between the door and other parts are mainly isolated by the pushing force generated by the door lock, resulting in poor sealing of traditional protective devices. This allows radiation to easily be transmitted to the outside through the gaps, leading to poor protection. Utility Model Content

[0004] The purpose of this invention is to provide a radiation protection device for X-ray flaw detection, which can improve sealing and prevent radiation from escaping to the outside world, thus solving the problems in the prior art.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1-4 The present invention discloses a radiation protection device for X-ray flaw detection, comprising a base 1 and a protective frame 2. The protective frame 2 is provided at the upper end of the base 1. The inner sides of the base 1 and the protective frame 2 are made of lead material and coated with a radiation-proof coating. The protective frame 2 is a rectangle with a hollowed-out lower end and center. An electric push rod 3 is provided at the upper end of the base 1, and a limit rod 31 is provided at the upper end of the electric push rod 3.

[0021] It should be noted that the inner sides of the base 1 and the protective frame 2 are made of lead material to provide radiation protection, and the radiation protection coating can further improve the radiation protection effect of the equipment.

[0022] In this embodiment, the bottom of the protective frame 2 is provided with an arc-shaped card plate 4, and the bottom of the card plate 4 is provided with a downward vertical positioning rod 41 at equal angles. The lower end of the positioning rod 41 is provided with a card block 42 at equal distances. The interior of the base 1 is provided with a groove to engage with the positioning rod 41 and the card block 42.

[0023] It should be noted that the base 1 and the protective frame 2 can be moved upwards to separate. When the protective frame 2 moves downwards, the locking plate 4, the positioning rod 41 and the locking block 42 will move downwards and embed into the base 1. The base 1 has a corresponding groove inside, which can improve the connection between the base 1 and the protective frame 2 and prevent radiation from escaping to the outside.

[0024] In this embodiment, a roller 11 is provided at the bottom corner of the base 1, a support platform 12 is provided on the side of the base 1, an operating rod 13 is internally threaded to the support platform 12, and a support seat 14 is rotatably provided at the lower end of the operating rod 13.

[0025] It should be noted that the rollers 11 can reduce the friction between the equipment and the ground, thus facilitating the movement of the equipment. When the equipment is in use, since the support platform 12 and the operating rod 13 are threadedly connected, rotating the operating rod 13 will cause it to move downwards, and the support base 14 will move downwards to contact the ground, thereby preventing the equipment from moving during use and increasing the stability of the equipment during use.

[0026] In this embodiment, the limiting rod 31 passes through the upper end of the protective frame 2, and the upper end of the protective frame 2 is provided with a limiting mechanism. The protective frame 2 is slidably disposed inside the limiting mechanism.

[0027] In this embodiment, the limiting mechanism includes a fixed post 21 and a fixed cap 22. The fixed post 21 is disposed at the upper end of the protective frame 2, and the fixed cap 22 is threadedly connected to the inside of the protective frame 2. The limiting rod 31 is slidably disposed inside the fixed post 21. The upper end diameter of the limiting rod 31 is larger than the lower end diameter of the limiting rod 31. A compression spring 32 is disposed on the outer side of the end of the fixed post 21 located inside the fixed post 21.

[0028] It should be noted that the electric push rod 3 will drive the limit rod 31 to move up and down. When the limit rod 31 moves upward, it will push the fixing cap 22 and the protective frame 2 to move, thereby separating the protective frame 2 from the base 1. When the electric push rod 3 drives the limit rod 31 downward, it will drive the protective frame 2 to move downward, thereby sealing the equipment. Furthermore, when the limit rod 31 moves downward, after the protective frame 2 moves to the bottom, as the limit rod 31 continues to move downward, the compression spring 32 will be squeezed to increase the downward pressure of the protective frame 2, preventing radiation from escaping to the outside.

[0029] In this embodiment, a limiting groove is provided at the upper end of the fixing cap 22, and a sealing ring 23 is embedded inside the fixing cap 22.

[0030] It should be noted that the fixing post 21 and the fixing cap 22 are fixed by a threaded connection, and a sealing ring 23 is provided between the fixing post 21 and the fixing cap 22 to prevent radiation from escaping to the outside.

[0031] Working principle: The roller 11 reduces the friction of the equipment, thereby moving the equipment to the required position. Then, the operating lever 13 is rotated to move the support base 14 downward, thereby increasing the connection between the equipment and the ground and increasing the stability of the equipment.

[0032] Then, the electric push rod 3 drives the protective frame 2 to move upward. The testing equipment is placed on the surface of the base 1, and the material to be tested is placed on the surface of the base 1. The electric push rod 3 drives the protective frame 2 to move downward. When the protective frame 2 contacts the base 1, the clamping plate 4, the positioning rod 41, and the clamping block 42 will be embedded in the base 1, thereby increasing the sealing between the base 1 and the protective frame 2. The downward movement of the limiting rod 31 will also cause the compression spring 32 to compress, thereby preventing the protective frame 2 from moving downward while applying downward pressure to the protective frame 2, and preventing the protective frame 2 from separating from the base 1.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
