Description

Technical Field

[0001] The present invention relates to the technical field of measuring instrument support tools, in particular to a heavy-load large-size foam bracket structure. Background Art

[0002] In target scattering measurements, the support structure for the target is one of the most significant sources of background noise. Based on its mechanical and electrical properties, foam is an excellent material for low-scattering RCS supports for heavy targets. Therefore, foam supports are commonly used as low-scattering supports for targets in open-field radiation and scattering measurements. However, due to the size limitations of commercially available foam (maximum dimensions are 1200mm × 1200mm × 5500mm), they are not suitable for supporting heavy, large targets.

[0003] Therefore, in view of the above shortcomings, it is necessary to provide a heavy-loaded large-size foam bracket structure. Summary of the Invention

[0004] (1) Technical issues to be solved

[0005] The technical problem to be solved by the present invention is to solve the problem that the foam brackets currently on the market cannot bear heavy and large-sized objects.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, the present invention provides a heavy-loaded large-size foam bracket structure, including a middle block, side blocks and connecting blocks, wherein several middle blocks are arranged side by side in the horizontal direction, two side blocks are placed on both sides of a row of middle blocks to form a layer structure, and several layer structures are arranged in a truncated cone shape in the vertical direction. The length directions of the middle blocks and side blocks in adjacent layer structures are perpendicular to each other, and several connecting blocks are embedded between the two layer structures.

[0008] As a further explanation of the present invention, preferably, the middle block is a long strip structure with a trapezoidal cross-section, and the end portion of the middle block is arc-shaped; the side block is a strip structure with a fan-shaped cross-section, and the lengths of the middle block and the side block of each layer of the structure are different.

[0009] As a further illustration of the present invention, preferably, the connecting surfaces of the middle block and the edge blocks of the adjacent layers are both provided with elongated grooves, and the elongated connecting blocks are embedded in the grooves.

[0010] As a further illustration of the present invention, preferably, the top end surfaces of the uppermost middle blocks and the side blocks are on the same horizontal plane, and the bottom end surfaces of the lowermost middle blocks and the side blocks are on the same horizontal plane; the middle blocks and side blocks between the uppermost and lowermost layers are provided with concave portions on the top and convex portions on the bottom, and after each layer of middle blocks and side blocks are arranged, the convex portions and concave portions are both circular.

[0011] As a further illustration of the present invention, preferably, the middle block, the side blocks and the connecting blocks are all made of foam.

[0012] (3) Beneficial effects

[0013] The above technical solution of the present invention has the following advantages:

[0014] The present invention uses small-sized foam in combination with a reasonable structural design. By cross-stacking into a truncated cone-shaped bracket, the foam bracket can maintain its low scattering characteristics while improving the bearing capacity. The number of stacked layers and columns can also be adjusted according to the target size to improve adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] A heavy-loaded large-size foam support structure, combined with Figure 1 、 Figure 2 , including middle blocks 1, side blocks 2 and connecting blocks 3. Several middle blocks 1 are arranged side by side in the horizontal direction, two side blocks 2 are placed on both sides of a row of middle blocks 1 to form a layer structure, and several layers of structures are arranged in a truncated cone shape in the vertical direction. The length directions of the middle blocks 1 and side blocks 2 in adjacent layer structures are perpendicular to each other, and several connecting blocks 3 are embedded between the two layers of structures.

[0023] Combine Figure 1 、 Figure 2 The middle block 1 is a long strip structure with a trapezoidal cross section, and the end of the middle block 1 is arc-shaped. The side block 2 is a strip structure with a fan-shaped cross section, and the connecting block 3 is a slender strip structure. The middle block 1 and the adjacent layer of side blocks 2 are provided with long strip grooves on their connecting surfaces. After the foam bracket is assembled, the long strip connecting block 3 can be embedded in the groove to complete the fixation. The middle block 1, side blocks 2 and connecting blocks 3 are all made of foam material. The lengths of the middle blocks 1 and side blocks 2 of each layer are different. Considering the outer diameter of the foam bracket and the size of the foam on the market today, the number of middle blocks 1 and side blocks 2 in each layer is as small as possible.

[0024] Combine Figure 2 、 Figure 3 The top surfaces of the topmost middle block 1 and side blocks 2 are on the same horizontal plane, while the bottom surfaces of the bottommost middle block 1 and side blocks 2 are on the same horizontal plane. The middle blocks 1 and side blocks 2 between the top and bottom layers have concave portions 12 on their tops and convex portions 11 on their bottoms. After each layer of middle blocks 1 and side blocks 2 is arranged, both the convex portions 11 and concave portions 12 are circular and have inverted trapezoidal cross-sections. By providing a concave-convex interface with a certain inclination, and leaving a sufficient outer diameter for the concave layer, the stacked foam brackets, in conjunction with the connecting blocks 3, have a satisfactory structural strength.

[0025] In an open test area, considering the impact of wind on the foam, the aforementioned structural design allows the middle block 1 and side blocks 2 to be stacked together. The inclined dividing surfaces ensure that the middle block 1 and side blocks 2 are mutually restrained and integrated. Furthermore, the middle block 1 and side blocks 2 are configured as elongated strips with trapezoidal cross-sections. This reduces the geometric characteristics of the foam strips and reduces the difficulty of processing and molding, while ensuring that the stacked foam support structure remains restrained and meets the design strength requirements. Furthermore, the combination of the protrusions 11 and recesses 12 allows the upper and lower layers to be locked together, preventing the foam strips from blowing away in windy conditions, thus providing the foam support with excellent wind resistance.

[0026] Combine Figure 4 、 Figure 5 Using the above structure, a foam tower with a bottom diameter of Φ5250mm and a height of 4100mm was designed, and it successfully passed the load test of bearing 11t, indicating that the foam tower structure designed by the present invention has excellent practicality.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
