Description

Technical Field

[0001] This invention relates to the field of neutron conduit installation structures, and in particular to an installation base that facilitates the docking and installation of neutron conduits. Background Technology

[0002] A neutron conduit is a device used to guide and focus a neutron beam, commonly used in neutron scattering experiments, neutron diffraction, and other neutron-related research and applications. The neutron conduit plays a crucial role in ensuring the neutron flux at the spectrometer terminal. Since the neutron conduit is the neutron transport channel, the accuracy of its installation position affects the neutron flux at the spectrometer terminal. Therefore, before conducting neutron-related experiments, the neutron conduit needs to be accurately installed and positioned; that is, the neutron conduit is mounted on a base, and the accuracy of its position is ensured through a collimation adjustment mechanism. The existing neutron conduit mounting base uses precast concrete blocks. After the precast concrete is installed on-site, steel plates are poured on-site onto the blocks. These steel plates are then connected to the neutron conduit alignment bracket for coarse positioning and support. Due to the limited adjustment range of the alignment bracket, the positional accuracy of the embedded steel plates connected to it is crucial. During steel plate embedding, on-site workers use alignment instruments and the alignment mechanism to adjust the plates to their precise positions before concrete pouring, integrating the steel plates with the precast base. This process results in a lengthy on-site fabrication time for the concrete base and embedded steel plates, requiring extensive concrete pouring. Furthermore, specialized alignment personnel are needed to adjust the embedded steel plates to meet positioning requirements, a labor-intensive process. The large quantity of embedded steel plates used across the entire base surface leads to high costs. Finally, dismantling and disposing of the base later is time-consuming, labor-intensive, and costly. The concrete base and steel support required for the neutron conduit installation platform can be prefabricated by the manufacturer, and the manufacturer can use relatively simple methods to ensure its accuracy during the manufacturing process. Furthermore, no alignment personnel or professional instruments are required for position adjustment during on-site installation, which saves manpower. In addition, if the platform is to be dismantled later, the steel support can be recycled and reused, and the amount of concrete platform used is small, saving on concrete platform disposal costs. Summary of the Invention

[0016] The technical effects and advantages of this invention are as follows:

[0017] The main body of the installation base of this invention consists of a precast concrete base and a steel support frame arranged alternately. The steel support frame includes a support platform and a aligning support frame installed on the support platform. By combining the aligning support frame and the support platform, the steel support frame is erected at the docking point of the neutron conduit body. In this way, when the neutron conduit body is docked and installed, it is not necessary to use the method of pouring concrete beforehand. Through the cooperation of the support platform and the aligning support frame, the docking and installation can be adjusted completely. This not only realizes the adjustment of the installation, but also makes the entire installation operation more convenient. If an error occurs, it is not necessary to recast the concrete base, thus reducing material waste and making the installation operation more convenient.

The steel support of this invention includes a support platform and a collimation bracket installed on the support platform. The collimation bracket includes a connecting structure and an adjusting base, and is installed on the support platform through the adjusting base. This reduces the on-site fabrication time of the concrete base and the embedded steel plate for the neutron conduit, and also... The invention eliminates the need for extensive concrete pouring and the simultaneous requirement for professional alignment personnel to adjust the position of the embedded steel plates to meet positioning requirements. The entire pouring and installation process is simplified and less costly. The concrete base and steel support required for the neutron conduit installation platform can be prefabricated at the factory, which can employ simple methods to ensure accuracy. Furthermore, no alignment personnel or specialized instruments are needed for on-site positioning, saving manpower. If the base is subsequently dismantled, the steel support can be recycled and reused, reducing the amount of concrete used and saving on concrete base disposal costs. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides, for example Figure 1-6 The installation base shown is for easy docking and installation of neutron conduit, including a precast concrete base 2 and a steel support 3. The steel support 3 is installed at intervals with the precast concrete base 2, and the neutron conduit body 1 is installed on the steel support 3.

[0028] It should be noted that the neutron conduit body 1 is typically constructed from a highly neutron-reflective material with a smooth surface, used to reflect neutrons and guide them to research equipment, such as neutron scattering instruments or detectors. The conduit's design and shape can be optimized according to research needs to ensure high intensity and directionality of the neutron beam. Neutron conduits are widely used in neutron diffraction, neutron scattering, neutron imaging, neutron radiation therapy, and other neutron-related research fields. Types of neutron conduits include straight conduits, curved conduits, and focusing conduits, their designs depending on experimental requirements. Focusing conduits can concentrate the neutron beam into a small area, improving neutron beam intensity and resolution. In actual setup, the neutron conduit body 1 is composed of multiple pipes spliced ​​together to form a complete neutron transmission channel, with the pipes connected via flanges.

[0029] The steel support 3 includes a support platform 307 and a collimation support installed on the support platform 307. The collimation support includes a connecting structure and an adjusting base, and is installed on the support platform 307 through the adjusting base. The connecting structure is a regularly shaped, through-hole frame structure 4. The adjusting base is bolted to the bottom of the horizontal beam of the frame structure 4. The neutron conduit body 1 passes through the frame structure 4 and is bolted to the inside of the frame structure 4. The position of the neutron conduit body 1 is collimated and adjusted by adjusting the adjusting base.

[0030] Specifically, the steel support 3 includes a support platform 307 and a support base plate 305. Two steel legs 301 for connecting the two are provided between the bottom end of the support platform 307 and the top end of the support base plate 305. A aligning support is provided at the top end of the support platform 307.

[0031] It should be noted that the steel bracket 3 is used to support the neutron conduit body 1. Both the support platform 307 and the support base plate 305 are rectangular steel plate structures. The support platform 307, the steel legs 301 and the support base plate 305 are combined to form a steel frame body. This body form forms the support platform 307, which is used to support the neutron conduit body 1. In this scheme, the steel legs 301 are horizontally and symmetrically arranged between the bottom end of the support platform 307 and the top edge of the support base plate 305.

[0032] Furthermore, a supporting horizontal steel 304 for reinforcing the support is provided between the horizontally opposite sides of the steel support leg 301.

[0033] It should be noted that the horizontal support steel 304 is horizontally positioned between the middle of the steel support legs 301, thus forming a rectangular structure in the middle of the steel support legs 301. This structure strengthens the support strength of the entire frame and ensures the overall support strength of the frame.

[0034] Furthermore, a top diagonal brace 302 is provided between the bottom edge of the support platform 307 and the top of the steel leg 301, and a bottom diagonal brace 303 is provided between the top edge of the support base plate 305 and the bottom of the steel leg 301.

[0035] It should be noted that the top diagonal bracing steel member 302 and the bottom diagonal bracing steel member 303 are designed to facilitate the connection between the support platform 307 and the support base plate 305 and the steel support leg 301. This connection method has the structural feature of forming a triangular support at the connection point, making the connection structure more stable.

[0036] Furthermore, the bottom end of the support base plate 305 is provided with fixing bolts 306 for fixing the support base plate 305.

[0037] It should be noted that by setting the fixing bolts 306, the entire steel bracket 3 can be fixed by fixing the support base plate 305. With this setting, the steel bracket 3 can maintain stable support for the neutron conduit body 1.

[0038] Specifically, the precast concrete base 2 and the steel support 3 are arranged and installed at intervals on the same straight line, and the steel support 3 is located directly below the splice of the neutron conduit body 1.

[0039] It should be noted that the precast concrete base 2 is a concrete structure manufactured in a factory or prefabrication site, used as a base to support equipment, machinery, buildings, or other important structures. These bases are typically precisely measured and adjusted during manufacturing to ensure accuracy in their dimensions and geometry. Precast concrete bases 2 generally have highly accurate dimensions and geometry, thus providing stable support and precise installation. These bases can be manufactured according to specific application requirements, with different shapes, sizes, and load capacities. Precast concrete typically possesses excellent strength and durability, capable of withstanding significant loads and environmental impacts. The precast concrete base 2 used in this solution is a shorter support fixture, which facilitates pouring and adjustment.

[0040] Furthermore, the precast concrete base 2 uses concrete as the shielding material.

[0041] Specifically, the adjusting base includes a connecting plate 404. The top of the connecting plate 404 is provided with multiple fixing blocks 403 and a position adjusting plate 406. The multiple fixing blocks 403 are located around the position adjusting plate 406. Each side of the multiple fixing blocks 403 is provided with an adjusting screw assembly for positioning the position adjusting plate 406. The top of the adjusting screw assembly is abutted against the side of the position adjusting plate 406.

[0042] It should be noted that the frame structure 4 consists of two parts that fit together to form an enclosed fixed space. The inner wall of this fixed space matches the size of the outer wall of the neutron conduit body 1. With this configuration and the two parts of the frame structure 4 being fixed with screws, disassembly can be quickly achieved, allowing for replacement of the fitting position and facilitating the separation of the entire collimation support from the neutron conduit body 1.

[0043] Furthermore, the adjusting screw assembly includes adjusting screws 405 for front-back and left-right position adjustment and height adjusting bolts 402. Multiple adjusting screws 405 are threadedly connected to the sides of multiple fixing blocks 403. A top support plate 401 is provided at the bottom of the frame structure 4. The height adjusting bolts 402 are threadedly connected to the sides of the top support plate 401 in the vertical direction, and the bottoms of multiple height adjusting bolts 402 are fixedly connected to the top of the position adjusting plate 406.

[0044] It should be noted that the connecting plate 404, as the main body of the entire connecting seat, is the largest part of the entire connecting seat because it needs to support the entire connecting seat. The outer wall of the adjusting screw 405 is fitted with a positioning nut, and the position of the adjusting plate 406 can be adjusted by the positioning nut at the fitted position on the outer wall of the adjusting screw 405.

[0045] Furthermore, positioning nuts are provided on the outer wall of the height adjustment bolt 402, located at the top of the top support plate 401 and the top of the fixing block 403 respectively.

[0046] It should be noted that the height adjustment bolt 402 not only serves as a support connection, but also as a guide post for adjusting the support. By setting the height adjustment bolt 402, the vertical distance between the top support plate 401 and the position adjustment plate 406 can be adjusted.

[0047] It should be noted that in this design, three positioning nuts are provided. Two of them are located at the top and bottom of the top support plate 401, where they fit together. These two positioning nuts are used to position the top support plate 401. The last positioning nut is located at the top of the position adjustment plate 406 to lock the height adjustment bolt 402 and the position adjustment plate 406. In actual operation, when the support height needs to be adjusted, it is only necessary to rotate the connection between the positioning nuts at the top and bottom of the top support plate 401 and the height adjustment bolt 402. This also allows the frame structure 4 to more stably support the neutron conduit body 1. The adjusting screw 405 is pressed against the left, right, front, and back of the position adjustment plate 406. By rotating the adjusting screw 405, the position adjustment plate 406 can be adjusted, thereby adjusting the position of the frame structure 4, and the position of the neutron conduit body 1 is also adjusted accordingly.

[0048] Specifically, mounting holes for connecting the two are provided on the top edge of the connecting plate 404 and the top of the support platform 307.

[0049] It should be noted that in actual installation, at least two sets of alignment brackets need to be installed at the top of a support platform 307. By symmetrically setting two or more sets of alignment brackets at both ends of the multi-pipe connection of the neutron conduit body 1, synchronous adjustment and support can be performed, making the connection of the neutron conduit body 1 more stable. The installation holes are designed to facilitate the connection of the entire alignment bracket to the top of the support platform 307 by screwing.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
