Description

Technical Field

[0001] This application relates to the field of testing device technology, specifically to a concrete strength monitoring device. Background Technology

[0002] Concrete is characterized by high strength, long service life, and ease of molding. Therefore, it serves as a crucial foundation material for buildings. Under normal circumstances, concrete reaches its service strength after 28 days of drying. During this drying process, strength monitoring is necessary to determine the concrete's quality. Some concrete strength monitoring devices utilize vibration-damping bases to ensure stable operation. However, these existing devices still have technical shortcomings in practical application: the fixed spacing between the two roller seats in these devices cannot be adjusted according to the actual size of the concrete sample. When the sample size is small (less than the fixed spacing), it easily gets stuck between the roller seats, preventing proper delivery to the testing station and disrupting the continuity of the testing process. Summary of the Invention

An adjustment mechanism is provided on the side of the base plate away from the roller seat. The adjustment mechanism includes a transmission component and two sets of sliding components.

[0005] In addition, the concrete strength monitoring device provided in this application may also have the following additional technical features: In one alternative embodiment, the sliding member includes a movable plate and at least two adjusting blocks, the at least two adjusting blocks being respectively disposed in two sets of adjusting grooves, the movable plate being connected to the adjusting blocks on both sides, and the movable plate having reinforcing ribs connected to the adjusting blocks on both sides along the thickness direction, and the transmission member being tractively connected to the movable plate.

The bellows cover can stretch and contract as the adjustment blocks move to cover the top opening of the adjustment slot.

[0011] In one alternative embodiment, the first drive element includes a first hydraulic rod, one end of which is connected to the mounting bracket, and the other end of which is connected to the detection head to drive the detection head relatively closer to and relatively farther away from the base plate.

[0022] like Figure 1-3 As shown in the figure, this application provides a concrete strength monitoring device, which mainly includes a pressure mechanism 1 and an adjustment mechanism 2. The pressure mechanism 1 includes a base plate 11, a first driving member 12, a detection head 13, and two sets of roller seats 14. The base plate 11 is provided with two sets of adjustment grooves 15 spaced apart along the width direction. A mounting frame 16 is provided on the base plate 11. The first driving member 12 is disposed on the mounting frame 16 and is connected to the detection head 13 in a transmission manner and can drive the detection head 13 along a preset direction. The roller seat 14 extends along the length of the base plate 11, and the two sets of roller seats 14 are arranged at intervals along the width of the base plate 11. The adjustment mechanism 2 is located on the side of the base plate 11 away from the roller seat 14. The adjustment mechanism 2 includes a transmission component and two sets of sliding components. The sliding components are movably disposed in the adjustment groove 15 and are connected to the roller seat 14. The transmission component is connected to the sliding component and can drive the sliding component to slide along the length of the adjustment groove 15, so as to drive the two sets of roller seats 14 to move closer and further apart respectively.

[0023] In this embodiment, the concrete strength monitoring device is equipped with an adjustment mechanism 2. The adjustment mechanism 2 drives the roller seat 14 to slide along the adjustment groove 15. The distance between the two sets of roller seats 14 can be flexibly adjusted according to the actual size of the concrete test block to ensure normal transport of the test block and expand the device's adaptability range for test blocks of different specifications, thereby better adapting to the strength monitoring of concrete test blocks of different sizes.

[0024] like Figure 2-3 As shown, in one specific embodiment, the sliding member includes a movable plate 21 and at least two adjusting blocks 22. The at least two adjusting blocks 22 are respectively disposed in two sets of adjusting grooves 15. The movable plate 21 is connected to the adjusting blocks 22 on both sides. The movable plate 21 is provided with reinforcing ribs connected to the adjusting blocks 22 on both sides along the thickness direction. The transmission member is connected to the movable plate 21 in a transmission connection.

[0025] like Figure 2-3 As shown, in one specific embodiment, the adjustment mechanism 2 further includes at least two limiting rods 23. The length direction of the limiting rods 23 extends along the length direction of the adjustment groove 15. The two limiting rods 23 are respectively fixedly installed in the two sets of adjustment grooves 15. The adjustment block 22 is provided with a limiting hole 221 and is slidably connected to the limiting rod 23 through the limiting hole 221.

[0026] like Figure 2-3 As shown, in one specific embodiment, the transmission component includes a bidirectional screw 24 and a crank 25. The length of the bidirectional screw 24 extends along the width of the base plate 11, and the bidirectional screw 24 is movably connected to the base plate 11 through at least two spaced support plates 26 and bearings. The crank 25 is located at the end of the bidirectional screw 24. The bidirectional screw 24 is threadedly connected to a movable plate 21 to drive the movable plate 21 to move. Specifically, the movable plate 21 is fixed to the bottom of the adjusting block 22, and two movable plates 21 are spaced apart along the bottom of the base plate 11. The same bidirectional screw 24 is threadedly connected to the two movable plates 21. When the bidirectional screw 24 rotates, because its front and rear threads rotate in opposite directions, it will drive the two movable plates 21 to move towards or away from each other along the screw axis, thereby driving the top adjusting block 22 to move synchronously through the movable plates 21, ultimately realizing the adjustment of the distance between the front and rear sets of roller seats 14.

[0027] In this embodiment, a threaded transmission structure of bidirectional screw 24 and moving plate 21 is adopted, which has high transmission accuracy and can accurately control the moving distance of the two moving plates 21. This ensures that the spacing between the two roller seats 14 is adjusted evenly and accurately, avoiding the situation of concrete block conveying jam due to spacing adjustment deviation. In use, only the bidirectional screw 24 needs to be rotated to drive the front and rear roller seats 14 to move simultaneously. The adjustment operation is simple and efficient, without the need to adjust each individual roller seat 14 separately, thereby saving adjustment time and improving the preparation efficiency before testing.

[0028] like Figure 1 As shown, in one specific embodiment, the concrete strength monitoring device further includes a fixing mechanism 3, which includes a blocking plate 31, a fixing plate 32, and a second driving member 33. The blocking plate 31 and the fixing plate 32 are arranged at intervals along the length direction of the base plate 11. The second driving member 33 is connected to the fixing plate 32 and can drive the fixing plate 32 to move relatively closer to and relatively away from the blocking plate 31.

[0029] like Figure 1As shown, in one specific embodiment, the fixing mechanism 3 further includes an L-shaped mounting block, which is disposed on one side of the base plate 11 along its length. The second driving member 33 includes a second hydraulic rod, one end of which is connected to the L-shaped mounting block, and the other end is connected to the fixing plate 32 to drive the fixing plate 32 to move. Specifically, the L-shaped mounting block provides mounting support for the second hydraulic rod. When the concrete test block is transported to the testing station via the roller seat 14, the second hydraulic rod is activated, and its output end drives the fixing plate 32 to move. In conjunction with the blocking plate 31, the test block is clamped and fixed from both sides. After the test is completed, the second hydraulic rod retracts, causing the fixing plate 32 to reset and releasing the fixing of the test block.

[0030] In this embodiment, the concrete test block is fixed by moving the fixing plate 32 through the second hydraulic rod. The fixing force can be flexibly adjusted by the hydraulic system, which can not only ensure that the test block does not shift during the test and avoid deviation of the test data, but also prevent the test block from being damaged due to excessive fixing. The blocking plate 31 and the fixing plate 32 cooperate to form a two-way fixing, which has strong fixing stability and further improves the stability of the test process, which is conducive to ensuring the accuracy of the test results.

[0031] like Figure 1 As shown, in one specific embodiment, a bellows cover 4 is provided on the top side of the adjustment slot 15. The two ends of the bellows cover 4 are respectively connected to two adjustment blocks 22. The bellows cover 4 can stretch and contract as the adjustment blocks 22 move to cover the top opening of the adjustment slot 15. Furthermore, the first driving member 12 includes a first hydraulic rod. One end of the first hydraulic rod is connected to the mounting bracket 16, and the other end is connected to the detection head 13 to drive the detection head 13 to move relatively closer to and relatively further away from the base plate 11.

[0032] The concrete strength monitoring device in this application operates on the following principle: Before use, the first hydraulic rod is in the retracted state, the detection head 13 is at its highest position, the second hydraulic rod is in the retracted state, the fixing plate 32 is located on the far right, reserving a channel for transporting the test block, the roller seat 14 is at the initial spacing, and the adjusting block 22 is in a stable position within the adjusting groove 15. During use, the spacing of the roller seat 14 is adjusted according to the size of the test block. The operator manually rotates the handle 25 at the front end of the bidirectional screw 24. The handle 25 amplifies the torque, causing the bidirectional screw 24 to rotate around its own axis. The front and rear threads of the bidirectional screw 24 have opposite directions of rotation and are movably connected to the support plate 26 via bearings. The support plate 26 provides stable support for the bidirectional screw 24 and reduces rotational friction. When the bidirectional screw 24 rotates, the two moving plates 21 connected to it by threads are subjected to the thread force along the screw. When the axes move in opposite directions or away from each other, the moving plates 21 move towards each other when the concrete test block is small, reducing the distance between the roller seats 14. When the concrete test block is large, the moving plates 21 move away from each other, increasing the distance. The moving plates 21 simultaneously drive the top adjusting block 22 to slide along the adjusting groove 15. At this time, the limiting hole 221 inside the adjusting block 22 slides synchronously along the limiting rod 23. The limiting rod 23 restricts the adjusting block 22 to move only in the front and back direction, preventing the roller seats 14 from tilting due to deviation. As the adjusting block 22 moves, the roller seats 14 adjust the distance synchronously until it matches the size of the concrete test block to be tested. During the adjustment process, the bellows cover 4 extends and retracts synchronously with the movement of the adjusting block 22, always covering the opening of the adjusting groove 15 to prevent impurities from entering the groove and affecting the operation of the components. Then the test block is sent to the testing station.

[0033] The operator places the concrete test block to be tested smoothly on the front and rear sets of roller seats 14, and pushes the test block to slide along the surface of the roller seat 14 until the left side of the test block contacts the left side of the base plate 11 blocking plate 31. At this time, the test block is exactly below the detection head 13, and the conveying stops. Then, by activating the second hydraulic rod, the output end of the second hydraulic rod extends, driving the fixing plate 32 to move to the left. When the right side of the fixing plate 32 is in close contact with the right side of the test block, the second hydraulic rod stops extending. At this time, the test block is clamped and fixed by the left side blocking plate 31 and the right side fixing plate 32. After the fixing is completed, the mounting frame 1 is activated. The first hydraulic rod at the top of the 6th internal part slowly extends downward, driving the detection head 13 fixed at the bottom to move downward synchronously. When the bottom of the detection head 13 contacts the top surface of the test block, the first hydraulic rod continues to apply pressure. The detection head 13 continuously applies pressure to the test block, and the pressure value can be monitored and recorded in real time through the hydraulic system. During the continuous pressure application, the pressure data of the test block from the moment it is subjected to force to the appearance of cracks and final failure is recorded by the matching pressure monitoring system. Based on the maximum pressure value when the test block fails, combined with the size parameters of the test block, the strength value of the concrete test block is calculated, and the test is completed.

[0034] In summary, this embodiment of the application, by setting an adjustment mechanism 2, drives the roller seat 14 to slide along the adjustment groove 15, and can flexibly adjust the distance between the front and rear sets of roller seats 14 according to the actual size of the concrete test block, ensuring normal transport of the test block and expanding the adaptability range of the device to test blocks of different specifications. The adjustment blocks 22 on the left and right sides of the bottom of the roller seat 14 are slidably connected in the adjustment groove 15. The adjustment blocks 22 can slide back and forth along the adjustment groove 15, thereby driving the top roller seat 14 to move synchronously, realizing the adjustment of the distance between the roller seats 14. The transmission component at the bottom of the adjustment block 22 provides power for the sliding of the adjustment block 22, and the internal limiting component restricts the sliding direction of the adjustment block 22 to prevent it from deviating during sliding. This solves the problem that in the transport structure of this device, the distance between the two roller seats 14 is fixed and cannot be adjusted according to the actual size of the concrete test block.
