Description

Technical Field

[0001] This utility model relates to the field of building material sample preparation technology, specifically to a sample preparation device for autoclaved aerated concrete blocks. Background Technology

[0002] In the field of building materials testing, the testing of mechanical properties, durability, and other indicators of autoclaved aerated concrete (AAC) blocks requires the preparation of standard test specimens. Currently, the industry commonly uses a method of manually marking the surface of the AAC block with a steel ruler and then cutting it with a cutting saw.

[0003] This method has significant drawbacks: First, poor positioning accuracy. During manual operation, the steel ruler is prone to deviation, and it is difficult to ensure the parallelism and dimensional consistency of multiple sample locations, resulting in the cut samples not meeting standard requirements and affecting the accuracy of the test data. Second, low operational efficiency. Operators need to measure and mark each sampling location one by one, a tedious process. After marking, additional information such as the sample number must be marked, which is time-consuming and labor-intensive. Utility Model Content

The first slide rail is perpendicular to the first base plate. The first measuring block is fixedly mounted on the slide rail, and the first measuring block is positioned between the first base plate and the first plate. The system has a first spacing; the second measuring block is slidably disposed on the slide rail; the third measuring block is slidably disposed on the slide rail; the driving unit includes: a first rack, a second rack, and a gear; the first rack is placed on the first slide rail and is fixedly connected to the first slide rail, the second rack is placed on the second slide rail and is slidably connected to the second slide rail, and the first rack and the second rack are arranged opposite to each other; the gear meshes with the first rack and the second rack respectively; the gear is rotatably disposed on the second measuring block, and the second rack is fixedly connected to the third measuring block.

[0006] Furthermore, it also includes a second substrate, which is slidably disposed on the slide rail and fixedly connected to the third measuring block. The second substrate is parallel to the first substrate and is used to abut against the other end of the concrete block. The third measuring block and the second substrate have a second gap.

[0007] Furthermore, the first spacing is equal to the second spacing.

[0008] Furthermore, the second substrate includes a body and an extension, the extension being fixedly disposed below the body and used to abut against the other end of the concrete block.

[0026] Please see Figures 1 to 4 This embodiment provides a sample preparation device for autoclaved aerated concrete blocks, including a first base plate 1, a slide rail 2, a first measuring block 3, a second measuring block 4, a third measuring block 5 and a driving unit 6. The first base plate 1 is vertically arranged and is used to abut one end of the concrete block. The slide rail 2 includes a first slide rail 21 and a second slide rail 22. The first slide rail 21 and the second slide rail 22 are arranged parallel to each other, and both the first slide rail 21 and the second slide rail 22 are fixedly arranged on the first base plate 1. The first slide rail 21 is arranged perpendicular to the first base plate 1. The first measuring block 3 is fixedly disposed on the slide rail 2, and there is a first distance between the first measuring block 3 and the first substrate 1; the second measuring block 4 is slidably disposed on the slide rail 2; the third measuring block 5 is slidably disposed on the slide rail 2. The drive unit 6 includes a first rack 61, a second rack 62, and a gear 63; the first rack 61 is placed on the first slide rail 21 and is fixedly connected to the first slide rail 21; the second rack 62 is placed on the second slide rail 22 and is slidably connected to the second slide rail 22; the first rack 61 and the second rack 62 are arranged opposite to each other; the gear 63 meshes with the first rack 61 and the second rack 62 respectively; the gear 63 is rotatably mounted on the second measuring block 4; and the second rack 62 is fixedly connected to the third measuring block 5.

[0027] The first substrate 1 is a flat plate structure, preferably made of low-carbon steel plate, which is sturdy, durable, and not easily damaged. The dimensions of the first substrate 1 can be set to a width of 600mm × a height of 200mm × a thickness of 10mm, which can be adjusted according to the dimensions of the autoclaved aerated concrete block. The first substrate 1 is vertically set, and its surface abuts against the concrete block to prevent the concrete block from moving during the marking operation, which would cause deviations in the marking and affect the subsequent cutting and sampling of the concrete block.

[0028] The first slide rail 21 and the second slide rail 22 are vertically arranged on the first base plate 1, that is, both the first slide rail 21 and the second slide rail 22 are horizontally arranged, parallel to each other, and at the same height. Both the first slide rail 21 and the second slide rail 22 can be made of stainless steel and can be fixed to the first base plate 1 by welding or threaded connection to form a stable double guide rail structure, providing a moving path for the second measuring block 4 and the third measuring block 5.

[0029] The first measuring block 3, the second measuring block 4, and the third measuring block 5 are all block-shaped structures, with the second measuring block 4 located precisely in the center of the first measuring block 3 and the third measuring block 5. All three are preferably made of stainless steel, which is wear-resistant, sturdy, and reliable. The dimensions of the first measuring block 3 are the same as those of the second measuring block 4 and the third measuring block 5. The length and width of all three measuring blocks are 100×100mm, allowing for the marking of a 100×100mm square on the concrete block for easy cutting and ensuring sample size consistency, thus reducing subsequent testing errors.

[0030] The first spacing refers to the distance between the side of the first measuring block 3 closest to the first substrate 1 and the first substrate 1, which is a horizontal distance. The first spacing is preferably 30 mm. When using the first measuring block 3 to mark lines, it is used to avoid damaged or pore-dense areas at the ends of the concrete blocks, ensuring the material uniformity of the sampling location. At the same time, the size of the first spacing can be adjusted according to the size of the concrete blocks, rather than being constant.

[0031] The second measuring block 4 and the third measuring block 5 are slidably disposed on the slide rail 2. Specifically, through holes can be provided on the second measuring block 4 and the third measuring block 5, and the second measuring block 4 and the third measuring block 5 are sleeved on the slide rail 2 through the through holes, thereby realizing the slidable connection between the second measuring block 4 and the third measuring block 5 and the slide rail 2. Alternatively, a groove can be provided on the slide rail 2, and a protrusion can be provided on the second measuring block 4 and the third measuring block 5. The protrusion is slidably disposed in the groove, thereby driving the second measuring block 4 and the third measuring block 5 to slide along the slide rail 2.

[0032] Both the first rack 61 and the second rack 62 are spur racks, and the gear 63 is a spur gear. The first rack 61 can be fixed to the inner wall of the first slide rail 21 by screws, and the second rack 62 is slidably connected to the inner wall of the second slide rail 22 by a slider. The gear 63 meshes with both the first rack 61 and the second rack 62.

[0033] Specifically, the first base plate 1 serves as a reference surface, forming a fixed positioning point after abutting against one end of the concrete block; the slide rail 2 is set perpendicular to the first base plate 1 to ensure that the moving direction of the second measuring block 4 and the third measuring block 5 is consistent with the length direction of the concrete block, avoiding mark offset. The first measuring block 3 is fixed to one end of the slide rail 2, maintaining a fixed first distance from the first base plate 1, serving as the reference for the first sampling position; the second measuring block 4 and the third measuring block 5 slide through the slide rail 2, and the drive unit 6 is driven by gear and rack meshing. When the third measuring block 5 is pushed to move along the slide rail 2, it moves synchronously with the second rack 62 fixed to it, driving the meshing gear 63 to rotate. The gear 63 further drives the meshing first rack 61 (fixed to the slide rail 2) to generate a reaction force, thereby driving the second measuring block 4 to move synchronously along the slide rail 2. Since the gear and rack transmission ratio is fixed, the second measuring block 4 always remains in the exact middle position between the first measuring block 3 and the third measuring block 5, achieving equidistant distribution of the three sampling positions. Next, apply ink to the bottom of the first measuring block 3, the second measuring block 4, and the third measuring block 5. By pressing, three 100×100mm square lines are formed on the concrete block for subsequent cutting.

[0034] Compared with the prior art, this embodiment sets up a first measuring block 3, a second measuring block 4, and a third measuring block 5. It eliminates the need for manual drawing with a ruler. Standard lines can be obtained simply by applying ink to the bottom of the measuring blocks, avoiding the problem of inaccurate manual drawing. At the same time, it eliminates the need for repeated manual measurement of the spacing. The position of the second measuring block 4 can be automatically adjusted simply by moving the third measuring block 5, simplifying the operation process, reducing reliance on the skill level of the operator, and improving work efficiency.

[0035] Please see Figure 2 and Figure 4 In this embodiment, the sample preparation device for autoclaved aerated concrete blocks further includes a second substrate 7, which is slidably disposed on the slide rail 2 and fixedly connected to the third measuring block 5. The second substrate 7 is parallel to the first substrate 1 and is used to abut against the other end of the concrete block. A second distance is provided between the third measuring block 5 and the second substrate 7.

[0036] The second substrate 7 is made of the same material as the first substrate 1. The second substrate 7 is fixedly connected to the third measuring block 5 and can move synchronously on the slide rail 2 with the third measuring block 5.

[0037] The second spacing refers to the distance between the third measuring block 5 and the second substrate 7. This distance is in the horizontal direction, and the second spacing is preferably 30 mm (millimeters) to avoid the damaged and pore-dense areas at the ends of the concrete blocks during scribing sampling.

[0038] The second substrate 7 is arranged parallel to the first substrate 1, forming two opposing positioning surfaces. The distance between the two substrates can be adjusted by sliding the second substrate 7 to accommodate concrete blocks of different lengths. Since the second substrate 7 is fixedly connected to the third measuring block 5, when the second substrate 7 is moved, the third measuring block 5 moves synchronously along the slide rail 2, which in turn drives the second measuring block 4 to move through the drive unit 6. After the second substrate 7 abuts against the other end of the concrete block, it works together with the first substrate 1 to firmly clamp the concrete block, preventing the concrete block from shifting during the marking process.

[0039] While clamping the concrete block, the first substrate 1 and the second substrate 7 automatically adjust the sampling position, requiring no additional operation and greatly improving work efficiency.

[0040] In this embodiment, the first spacing is equal to the second spacing, so that the first measuring block 3 and the third measuring block 5 are at the same distance from the two ends of the concrete block, forming a symmetrical positioning reference. This keeps the sampling position away from the defect area at the end of the concrete block, ensuring that the specimen material is uniform and the test data is more representative and accurate.

[0041] Please see Figure 4 In this embodiment, the second substrate 7 includes a body 71 and an extension 72. The extension 72 is fixedly disposed below the body 71 and is used to abut against the other end of the concrete block.

[0042] The main body 71 is slidably mounted on the slide rail 2 and is fixedly connected to the third measuring block 5. Specifically, it can be fixed to the third measuring block 5 by welding.

[0043] The extension section 72 is vertically positioned below the main body 71 to abut against the other end of the concrete block. The width of the extension section 72 is smaller than the width of the first base plate 1, thereby reducing material usage, saving costs, and reducing the weight of the device for easy movement.

[0044] In this embodiment, the sample preparation device for autoclaved aerated concrete blocks further includes: a first marking strip, a second marking strip, and a third marking strip; The first marking strip is placed at the bottom of the first measuring block 3, and the first marking strip is adapted to the bottom edge of the first measuring block 3; the second marking strip is placed at the bottom of the second measuring block 4, and the second marking strip is adapted to the bottom edge of the second measuring block 4; the third marking strip is placed at the bottom of the third measuring block 5, and the third marking strip is adapted to the bottom edge of the third measuring block 5; the first marking strip, the second marking strip, and the third marking strip are used to mark on the concrete block.

[0045] The first, second, and third marking strips are all strip-shaped structures made of elastic rubber or thin metal sheets, set at the bottom edge of each measuring block to form a standard square; their surfaces can absorb printing ink or be coated with wear-resistant marking material to form clear marking outlines on concrete blocks.

[0046] Specifically, the marking strip is fitted to the bottom edge of the measuring block, ensuring that the marking line completely coincides with the positioning edge of the measuring block. During use, apply ink (or use a self-colored, wear-resistant marking material) to the surface of the marking strip, press down on the measuring block, and the marking strip will contact the concrete block surface, leaving a straight mark consistent with the positioning edge of the measuring block. This mark is the cutting boundary line of the specimen. Simultaneously, directional markings (such as "Up," "Middle," and "Down") can be set on the marking strip, and these markings will be simultaneously applied to the concrete block after pressing, facilitating management.

[0047] In this embodiment, the sample preparation device for autoclaved aerated concrete blocks further includes: a marking wheel; The bottom of the first measuring block 3, the second measuring block 4, and the third measuring block 5 are all provided with grooves, and the marking wheel is rolled in the grooves; and multiple serial numbers are sequentially provided on the periphery of the marking wheel.

[0048] There are three marking wheels, which are respectively set in the grooves at the bottom of the first measuring block 3, the second measuring block 4 and the third measuring block 5, and the marking wheels are flush with the surfaces of the first measuring block 3, the second measuring block 4 and the third measuring block 5.

[0049] The serial number on the marking wheel is used to mark the concrete blocks, making it easy to distinguish specimens from different batches and locations, and avoiding confusion during the test.

[0050] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
