Abstract
Description
Technical Field
[0001] The invention relates to the technical field of test block detection, in particular to a test block compression detection device for pouring concrete of a water conservancy dam body. Background Art
[0002] The compressive strength test of concrete blocks used in water conservancy dams uses standard test methods to determine the compressive strength of concrete specimens. This is done to assess the quality and durability of the concrete and ensure the safety of the dam structure. Cube specimens randomly sampled from the site are brought back to the curing room for curing. Upon completion of curing, they are removed and immediately tested. During the test, the specimen is placed in the center of a press, which continuously applies pressure. The failure load is recorded, thereby measuring the compressive strength of the specimen.
[0003] In particular, to measure the true compressive strength of the test block, the center of the test block and the center of the press need to be geometrically aligned before pressurization. Currently, the most commonly used method is manual visual adjustment. When placing the test block, the tester needs to use auxiliary tools such as a steel ruler to perform geometric alignment. However, on the one hand, this method is highly subjective and relies on the operator's operating experience and visual judgment, which is very prone to human error. On the other hand, during the manual visual adjustment process, in order to ensure accurate positioning, the position of the test block needs to be repeatedly adjusted, which will result in longer operation time and reduce the efficiency of continuous compression testing of multiple groups of test blocks.
[0004] However, when using a centering plate or a centering ring for geometric alignment, the centering plate and the centering ring have poor universality. Test blocks of different specifications need to be equipped with centering rings or centering plates of different specifications. When conducting compression tests on test blocks of different specifications, the corresponding centering rings or centering plates are repeatedly replaced, which will lead to the complexity of the overall test process and reduce the test efficiency.

DETAILED DESCRIPTION
[0034] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.
[0035] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
[0036] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.
[0037] See also Figures 1-10 In an embodiment of the present invention, a test block compression testing device for pouring concrete for a water conservancy dam body comprises: a placement platform 2 disposed in a press 1, wherein a placement cavity 201 is provided on the placement platform 2;
[0038] The placement cavity 201 is provided with an alignment mechanism, which includes a transverse alignment component and a longitudinal alignment component. The transverse alignment component is connected to two groups of alignment frames 12 symmetrically arranged along the length direction of the placement table 2, and the longitudinal alignment component is connected to two groups of alignment frames 12 symmetrically arranged along the width direction of the placement table 2. When the transverse alignment component is actuated, the longitudinal alignment component is actuated synchronously, and can drive the four groups of alignment frames 12 to approach the center of the placement table 2.
[0039] Specifically, see Figure 3 A centering mark 202 is provided on the above-mentioned storage platform 2, and the centering mark 202 is the center position of the storage platform 2. When performing a compressive test on the test block 5, the test block 5 needs to be placed on the storage platform 2 and aligned with the centering mark 202. At this time, the test block 5 and the pressure member 6 inside the press 1 are in a geometrically aligned state. Therefore, when performing a compressive test, the pressure member 6 can eliminate the additional bending moment and measure the true compressive strength of the test block 5.
[0040] In particular, see Figure 1 The press 1 is surrounded by fences 3, and the fence 3 on the front of the press 1 is only provided with the upper half, and a splash-proof door 4 is slidingly provided on the fence 3; when the pressure resistance test of the test block 5 is carried out, the splash-proof door 4 is closed, which can prevent the pressure-applying member 6 from collapsing or even splashing out of the press 1 when the pressure resistance test of the test block 5 is carried out, thereby reducing the operating risk of the test personnel during the pressure test.
[0041] For details, see Figure 4 The above-mentioned storage platform 2 is provided with guide grooves 203 along its length and width directions, and the alignment frame 12 is slidably set in the guide grooves 203. Under the restriction of the guide grooves 203, the alignment frame 12 can only slide along the length and width directions of the storage platform 2; at this time, with the cooperation of the four groups of alignment frames 12, the alignment frame 12 can push the test block 5 to be geometrically aligned with the centering mark 202, thereby facilitating subsequent compression testing.
[0042] The lateral alignment assembly includes a left shift plate 1502 and a right shift plate 1501 symmetrically arranged along the length direction of the storage platform 2, and also includes a deflection rod 11 rotatably installed in the storage cavity 201, with both ends of the deflection rod 11 hinged to the left shift plate 1502 and the right shift plate 1501 respectively through a hinge rod 22;
[0043] Specifically, the rotation center of the above-mentioned deflection rod 11 is coaxial with the center of the storage platform 2, and due to the connection of the hinged rod 22, when the deflection rod 11 rotates, the deflection rod 11 can pull or push the left-moving plate 1502 and the right-moving plate 1501 closer to or away from each other along the length direction of the storage platform 2, so that the symmetry axis of the test block 5 in the length direction is aligned with the symmetry axis in the length direction of the storage platform 2.
[0044] The longitudinal alignment assembly includes a forward plate 1401 and a rearward plate 1402 that are symmetrically arranged in a sliding manner along the width direction of the storage platform 2, and also includes two groups of connecting rods 13. The two groups of connecting rods 13 are rotatably connected to the two ends of the deflection rod 11, and the ends of the two groups of connecting rods 13 away from the deflection rod 11 are slidably arranged in the sliding grooves 27 provided on the forward plate 1401 and the rearward plate 1402 respectively.
[0045] It should be noted that the connecting rod 13 always remains parallel to the width direction of the storage platform 2 (specifically, the end of the connecting rod 13 is slidably set in the slide groove 27 and can only slide along the length direction of the slide groove 27). In combination with the above, when the deflection rod 11 rotates, it can drive the connecting rod 13 to slide along the width direction of the storage platform 2 while driving the connecting rod 13 to slide in the slide groove 27, so that the forward plate 1401 and the rearward plate 1402 are close to or away from each other along the width direction of the storage platform 2, thereby aligning the symmetry axis of the test block 5 in the width direction with the symmetry axis of the width direction of the storage platform 2; combined with the cooperation of the left plate 1502 and the right plate 1501, the geometric alignment of the test block 5 and the storage platform 2 is achieved.
[0046] Further, see Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 The positioning mechanism further includes a driving member disposed in the placement cavity 201, the driving member including an electric telescopic rod 10 fixedly disposed in the placement cavity 201, and the telescopic end of the electric telescopic rod 10 is fixedly connected to the left shift plate 1502;
[0047] The four groups of the straightening frames 12 are all fixedly provided with straightening plates 1201, and the four groups of the straightening frames 12 are all fixedly provided with plug-in rods 24, the plug-in rods 24 are correspondingly inserted into the insertion cavities opened on the left shift plate 1502, the right shift plate 1501, the front shift plate 1401 and the rear shift plate 1402, and the plug-in rods 24 are sleeved with springs 23, one end of the spring 23 abuts against the end of the plug-in rod 24, and the other end abuts against the inner wall of the insertion cavity;
[0048] Specifically, the spring 23 is always in a compressed state, pushing the plug rod 24 to move toward the inside of the insertion cavity.
[0049] In the initial state, the electric telescopic rod 10 is in an extended state. In combination with the above, when performing a compression test on the test block 5, the test block 5 is first manually placed on the storage table 2. At this time, there is a certain deviation between the center of the test block 5 and the center of the storage table 2; then, the electric telescopic rod 10 is started, and after the electric telescopic rod 10 performs a reciprocating motion, it automatically stops.
[0050] During the inward retraction of the telescopic end of the electric telescopic rod 10, the left-moving plate 1502 approaches the centering mark 202, and then the horizontal alignment component and the longitudinal alignment component act synchronously, driving the four groups of alignment frames 12 to move synchronously toward the center of the storage table 2; during the movement, the alignment plate 1201 contacts the side of the test block 5, which can push the test block 5 and the storage table 2 to be geometrically aligned; due to the different specifications of the test blocks 5, during the alignment process, the side of the test block 5 will produce reverse extrusion on the alignment plate 1201, so that the plug-in rod 24 protrudes from the insertion cavity, so that the alignment mechanism can perform alignment operations on test blocks 5 of different specifications and sizes, thereby improving the overall versatility of the device.
[0051] During the process of extending the telescopic end of the electric telescopic rod 10 outward, the electric telescopic rod 10 pushes the left shift plate 1502 away from the centering mark 202; then, the horizontal alignment component and the vertical alignment component operate synchronously, driving the four sets of alignment frames 12 to synchronously move away from the center of the storage table 2; after the electric telescopic rod 10 stops, the four sets of alignment frames 12 return to the initial position, so that the subsequent pressure-applying member 6 can perform a pressure test on the test block 5.
[0052] Further, see Figures 1-8 、 Figure 10 , a splash-proof assembly is provided in the press 1, and the splash-proof assembly includes a splash-proof door 4 slidably provided on the press 1, and the splash-proof assembly is connected to the lateral alignment assembly and the pressure member 6 through a closing assembly and an opening assembly respectively. When the lateral alignment assembly drives the alignment frame 12 away from the center of the storage table 2, the closing assembly can drive the splash-proof assembly to move and close the splash-proof door 4, and when the pressure member 6 rises, the opening assembly can drive the splash-proof assembly to move and open the splash-proof door 4;
[0053] The splash-proof assembly includes a first drive rod 7 rotatably mounted in the press 1, a second ratchet 18 being coaxially fixedly mounted on the first drive rod 7, and a sleeve 26 fixedly connected to the splash-proof door 4 being sleeved on the first drive rod 7, a first protrusion being fixedly mounted on the inner wall of the sleeve 26, and the first protrusion being slidably mounted in a closed groove 701 formed on the outer wall of the first drive rod 7;
[0054] In detail, the closed groove 701 is a spiral groove body opened around the outer wall of the first driving rod 7 .
[0055] The closing assembly includes a linkage rod 9 rotatably mounted in the press 1 , a first ratchet 17 being coaxially fixedly mounted on the linkage rod 9 , the first ratchet 17 cooperating with the second ratchet 18 , and the linkage rod 9 being connected to a linkage assembly disposed in the placement chamber 201 ;
[0056] The linkage assembly includes a gear 16 rotatably mounted in the placement cavity 201, the gear 16 being connected to the linkage rod 9 via a belt, and the gear 16 being engaged with a main gear plate 21 fixedly mounted on the right shift plate 1501 and a slave gear plate 20 fixedly mounted on the left shift plate 1502;
[0057] The opening assembly includes a second driving rod 8 rotatably mounted on the press 1. The second driving rod 8 is sleeved with a fixed sleeve 25 fixedly connected to the pressure member 6. A second protrusion is formed on the inner wall of the fixed sleeve 25. The second protrusion is slidably disposed in a spiral groove 801 formed on the outer wall of the second driving rod 8. Specifically, the central angle corresponding to the first and second ends of the spiral groove 801 is 180°. A third ratchet 19 coaxially fixedly mounted on the second driving rod 8 and cooperating with the second ratchet 18 is fixedly disposed.
[0058] In particular, see Figure 6 The outer walls of the first ratchet 17 and the third ratchet 19 are fixedly provided with a series of ratchets at equal intervals around their circumferential directions, and the outer ring of the second ratchet 18 is rotatably provided with a series of ratchets at equal intervals around its circumferential direction. The ratchets are elastically connected to the second ratchet 18 through spring plates so that the ratchet teeth on the second ratchet 18 are always in an open state, so that the second ratchet 18 can subsequently cooperate with the first ratchet 17 or the third ratchet 19.
[0059] In the initial state, the splash door 4 is in the open state, and the pressure member 6 is away from the storage table 2, so that the test personnel can place the test block 5; at this time, the fixing sleeve 25 and the sleeve 26 are respectively located at the upper ends of the second driving rod 8 and the first driving rod 7 (as shown in FIG. Figure 3 shown).
[0060] In combination with the above, when the alignment mechanism drives the four sets of alignment frames 12 to approach the center of the storage platform 2, the main gear plate 21 fixed to the left shift plate 1502 and the slave gear plate 20 fixed to the right shift plate 1501 can drive the gear 16 to rotate clockwise (refer to Figure 5Description), then, the rotating gear 16 drives the linkage rod 9 to rotate clockwise under the connection of the belt; during this process, the first ratchet 17 does not enter into a meshing transmission state with the second ratchet 18, so the second ratchet 18 and the first driving rod 7 remain stationary; subsequently, in the process of the straightening mechanism driving the four sets of straightening frames 12 away from the center of the storage table 2, the main tooth plate 21 and the slave tooth plate 20 can drive the gear 16 to rotate counterclockwise; during this process, the first ratchet 17 and the second ratchet 18 enter into a meshing transmission state, driving the second ratchet 18 to drive the first driving rod 7 to rotate clockwise, and at the same time, the third ratchet 19 is always in a stable and stationary state. State, and the rotating first driving rod 7, in cooperation with the closed groove 701 and the first protrusion, pulls the sleeve 26 and the splash-proof door 4 down along the axial direction of the first driving rod 7, and after the positioning frame 12 returns to the initial position, the gear 16 rotates half a circle, and with the cooperation of the first ratchet 17 and the second ratchet 18 of the linkage rod 9, drives the first driving rod 7 to rotate half a circle, so that the sleeve 26 drives the splash-proof door 4 to drop to the lowest position, and the press 1 is completely closed, thereby performing splash protection for subsequent pressure resistance tests, avoiding the test block 5 from collapsing fragments to splash out of the press 1 during the pressure resistance test, thereby improving the detection safety of the test personnel.
[0061] When the splash door 4 is completely closed, the pressure member 6 in the press 1 automatically enters the working state, descends toward the storage table 2, and pressurizes the test block 5. During this process, the second protrusion on the inner wall of the fixed sleeve 25 cooperates with the spiral groove 801, which can force the second driving rod 8 to rotate clockwise (refer to Figure 6 Description), during this process, the third ratchet 19 does not cooperate with the second ratchet 18, so the splashproof door 4 will not be forced to open during the pressure application of the pressure piece 6; when the pressure application process of the pressure piece 6 is over, the second protrusion cooperates with the spiral groove 801 during the automatic rise of the pressure piece 6, which can drive the second drive rod 8 to rotate counterclockwise, and then the third ratchet 19 and the second ratchet 18 enter a meshing transmission state, so that the second ratchet 18 drives the first drive rod 7 to rotate clockwise half a circle; during this process, the closed groove 701 cooperates with the first protrusion on the inner wall of the sleeve 26, which can force the sleeve 26 to drive the splashproof door 4 to gradually rise; until the pressure piece 6 returns to the initial position, the sleeve 26 rises to the highest point and drives the splashproof door 4 to fully open, exposing the storage table 2, so that the test personnel can clean the storage table 2, and at the same time facilitate the subsequent pressure resistance test of the test block 5 again.
