Description

Technical Field

[0001] The invention relates to the field of concrete compression resistance, and more particularly to a multifunctional concrete test block compression resistance testing device. Background Art

[0002] This measure measures the ability of concrete specimens to resist axial compression failure after curing under standard conditions. The so-called cube compressive strength is the ultimate compressive strength of concrete measured using standard test methods using standard test specimens with a side length of 150 mm, manufactured in accordance with the "Concrete Structure Construction Quality Acceptance Code." Cured in a humid environment at 20°C ± 20°C and a relative humidity of 95% or higher, or in a stagnant Ca(OH)2 saturated solution, for 28 days. The so-called prismatic compressive strength is often used as a basis for calculating axially compressed components in reinforced concrete structure calculations, based on the actual structural conditions, as it closely resembles the actual stress conditions of the concrete component. Because the frictional forces above and below the cube specimens under compression are greater than those of the prismatic specimens, the cube strength is higher than the prismatic compressive strength. Standard specimen dimensions include a 150mm × 150mm × 150mm cube, a 100mm × 100mm × 100mm cube, and a 150mm × 300mm cylinder.

[0003] A Chinese patent with authorization announcement number CN114659876B discloses a concrete compressive strength testing device. Before the rebound hammer contacts each detection point on the concrete detection surface, a calibration unit will pre-contact the detection surface at the detection point. Then the calibration unit adjusts the angle between the rebound hammer's impact rod and the concrete detection point to basically 90°. Thereafter, as the rebound hammer's impact rod gradually contacts the detection point, the calibration unit will completely fix the position of the rebound hammer to ensure that the rebound hammer's impact rod can contact the detection point in a basically vertical and stable manner, thereby effectively reducing the data error of the concrete compressive strength tested by the rebound hammer, thereby improving the judgment of the concrete compressive strength.

[0004] Although the above patent solves the problem that the angle between the impact rod and the detection point cannot be basically maintained at 90° during the manual operation of the rebound hammer, resulting in errors in the data of the concrete compressive strength tested by the rebound hammer, the compressive strength test requires multiple groups of tests. After each test, the debris generated by the crushing of the specimen needs to be cleaned, and the crushing chamber is a rectangular parallelepiped, which will have dead corners, making cleaning more troublesome. The residual debris can easily cause the test results to fluctuate, resulting in errors in the experimental data. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a multifunctional concrete specimen compression test device, in which the second rotating plate is horizontally located between two tooth grooves. When the first driving plate moves upward with the tooth groove, the tooth groove provides an upward force to the second rotating plate, and the second rotating plate is blocked by the first rotating plate and cannot rotate upward. The second rotating plate can then rotate upward with the first rotating plate, so that the first rotating plate is in an inclined state. At this time, the debris on the surface of the first rotating plate and the test block slide off the surface of the first rotating plate, which makes it more convenient to clean the debris on the surface of the first rotating plate. In addition, there are multiple tooth grooves, so that the first rotating plate can rotate multiple times and shake multiple times, which has a better effect on cleaning the debris on the surface of the first rotating plate and is more convenient to clean the debris in dead corners.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A multifunctional concrete specimen compression test device comprises a bracket, a hydraulic cylinder is fixedly connected to the top of the bracket, an output shaft end of the hydraulic cylinder passes through a test chamber and extends into the interior of the test chamber, the interior of the bracket is fixedly connected to the test chamber, and a cleaning mechanism is provided inside the test chamber;

[0008] The cleaning mechanism includes a accommodating box fixed to the inner wall of the experimental chamber, the top of the accommodating box is rotatably connected to a first rotating plate, the contact position of the experimental chamber and the output shaft of the hydraulic cylinder is tightly fitted, the end of the output shaft of the hydraulic cylinder is fixedly connected to a pressure plate, the rear side of the pressure plate is fixedly connected to a first driving plate, the rear side of the first rotating plate is rotatably connected to a second rotating plate, the rear side of the first rotating plate is provided with a through groove, the interior of the first driving plate is provided with a plurality of equidistantly distributed tooth grooves, and the width of the accommodating box is smaller than the width of the experimental chamber.

[0009] Furthermore, a columnar block is slidably connected to the interior of the first rotating plate, a ball is rotatably connected to the top of the columnar block, and the top of the ball is higher than the upper end of the first rotating plate.

[0010] Furthermore, a mounting block is fixedly connected to the interior of the accommodating box, a second movable groove for accommodating the movement of the column block is opened inside the mounting block, and an arc groove for accommodating the rotation of the column block is opened on the top rear side of the second movable groove.

[0011] Furthermore, the first rotating plate is slidably connected to the inside of the second driving plate, the rear side of the second driving plate and the contact surface with the first driving plate are arc surfaces, and the position of the columnar block inside the second driving plate extends toward the direction of the columnar block to form an extension block.

[0012] Furthermore, a limiting groove for accommodating the extension block is provided inside the columnar block, and an arc-shaped extrusion block is provided inside the second driving plate at a position corresponding to the columnar block.

[0013] Furthermore, a first moving groove is provided inside the first rotating plate corresponding to the moving position of the second driving plate, a first spring welded to the second driving plate is provided inside the first moving groove, and a fan-shaped groove is provided on the surface of the first rotating plate corresponding to the position of the ball.

[0014] Furthermore, a second spring welded to the mounting block is provided at the bottom of the columnar block, and a fan-shaped groove is provided at the top of the first rotating plate at a position corresponding to the ball.

[0015] Furthermore, a second flip door is rotatably connected to the bottom of the front side of the experimental chamber, and a first flip door rotatably connected to the experimental chamber is provided on the top of the second flip door.

[0016] Furthermore, a moving block is slidably connected to the front side of the first flip door, and opposite surfaces of the moving block are fixedly connected to limit plates.

[0017] Furthermore, the thickness of the limiting plate is smaller than that of the moving block, the distance between the opposite surfaces of the moving block is 150 mm, and the opposite surfaces of the limiting plate are provided with oblique grooves.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the first driving plate moves upward with the tooth groove, the tooth groove provides an upward force to the second rotating plate, and the second rotating plate is blocked by the first rotating plate and cannot rotate upward, and the second rotating plate can drive the first rotating plate to rotate upward, so that the first rotating plate is in an inclined state. At this time, the debris on the surface of the first rotating plate and the test block slide off the surface of the first rotating plate, which is more convenient to clean the debris on the surface of the first rotating plate. The tooth groove is provided with multiple teeth, so that the first rotating plate can rotate multiple times and the first rotating plate can be shaken multiple times, which has a better cleaning effect on the surface of the first rotating plate and is more convenient to clean the debris in the dead corner. The width of the storage box is smaller than the width of the experimental chamber. At this time, there is a cavity on the front side of the storage box, which is convenient for debris to fall on the front side of the storage box. There is no need to clean it after each measurement, which reduces the burden on the staff, and the debris collection area is staggered with the test block experimental area, effectively preventing the collected debris from affecting the measurement.

[0020] 2. This solution converts the sliding friction between the pressing block and the first rotating plate into rolling friction between the pressing block and the ball bearings, thereby facilitating the movement of the test block by the staff and making the test block position adjustment more convenient. When the first rotating plate rotates, the bottom of the columnar block rotates inside the arc groove, so that when the first rotating plate rotates to dump debris, the columnar block will not affect the rotation of the first rotating plate, making the rotation of the first rotating plate more convenient. Moreover, when large debris is tilted on the surface of the first rotating plate, the exposed ball bearings on the upper surface of the first rotating plate make it easier for the debris to slide down, especially for cleaning large debris.

[0021] When the second driving plate moves, the second driving plate moves with the extending block, and the extending block leaves the inner part of the limiting groove. At this time, the column block is not blocked by the extending block. At this time, the column block can move inside the first rotating plate. The arc-shaped extrusion block is an arc surface. During the movement of the second driving plate, the column block and the ball are squeezed and moved toward the mounting block, so that the ball moves from the upper surface of the first rotating plate to the inner part of the first rotating plate, which facilitates the contact between the ball and the test block and the transition from the contact between the first rotating plate and the test block to the contact between the first rotating plate and the test block. In the subsequent test block, it will not be affected by the ball when it is squeezed by the pressure plate, so that the compression test of the test block is more accurate, and the pressure of the test block will not act on the ball, thereby avoiding damage to the ball, and making the device more convenient to use.

[0022] 4. In this solution, when the ball is retracted into the interior of the mounting block, the second driving plate blocks the original position of the ball in the first rotating plate, which is used to block the debris generated when the test block on the surface of the first rotating plate is under pressure, effectively preventing the debris from entering the interior of the first rotating plate. After the second driving plate returns to its original position, the column block and the ball are no longer blocked by the second driving plate. At this time, the second spring squeezes the column block, so that the column block returns to its original position, blocking the debris on the surface of the first rotating plate again. A fan-shaped groove is provided on the top of the first rotating plate corresponding to the position of the ball. When the first rotating plate rotates, it effectively prevents the ball from blocking small debris. Small debris enters the fan-shaped groove, and the first rotating plate can make the debris entering the fan-shaped groove slide down when it rotates, which has a better effect on cleaning debris.

[0023] 5. This solution places the test block on the surface of the first flip door, aligns the corners of the test block with the three oblique grooves, and then moves the moving block so that the moving block moves with the test block on the surface of the first flip door. Then the test block leaves the surface of the first flip door. Since the first flip door and the first rotating plate are in the same horizontal plane, the test block reaches the surface of the first rotating plate. When the moving block can no longer push the test block to move, the test block is at the center position of the first rotating plate, making it more convenient for the test block to reach the center position of the first rotating plate and reducing the steps of adjusting the test block on the surface of the first rotating plate.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 8A multifunctional concrete specimen compression test device includes a bracket 1, and an experimental chamber 2 is fixedly connected to the inside of the bracket 1. By setting the experimental chamber 2, all debris generated during the compression test is blocked by the experimental chamber 2 to prevent debris from splashing and causing injury to the staff, and the debris is left inside the experimental chamber 2, which is convenient for the staff to clean up. A cleaning mechanism 3 is provided inside the experimental chamber 2, and the cleaning mechanism 3 includes a accommodating box 31 fixed to the inner wall of the experimental chamber 2. The top of the accommodating box 31 is rotatably connected to a first rotating plate 32, and the test block is placed on the top of the first rotating plate 32. The top of the bracket 1 is fixedly connected to a hydraulic cylinder 11. By starting the hydraulic cylinder 11, the output shaft of the hydraulic cylinder 11 moves, and the output shaft end of the hydraulic cylinder 11 passes through the experimental chamber 2 and extends The first rotating plate 32 is connected to the second rotating plate 32 by the second driving plate 121, and the second rotating plate 32 is connected to the second rotating plate 322 by the second driving plate 122. The second rotating plate 322 and the first rotating plate 32 are reset by a torsion spring and a rotating rod. The first driving plate 121 first squeezes the second rotating plate 322 to rotate the second rotating plate 322. After the second rotating plate 322 rotates, the first driving plate 121 can continue to move downward until the pressure plate 12 applies pressure to the test block. When the test block is broken, the pressure plate 12 brings the first driving plate 121 back to its original position. The first driving plate 121 is provided with a plurality of equally spaced tooth grooves 122. Under the action of the torsion spring, the second rotating plate 322 is horizontally located between the two tooth grooves 122. When the first driving plate 121 moves upward with the tooth grooves 122, the tooth grooves 122 provide an upward force to the second rotating plate 322, and the second rotating plate 3 The second rotating plate 322 can rotate upward with the first rotating plate 32, so that the first rotating plate 32 is in an inclined state. At this time, the debris on the surface of the first rotating plate 32 and the test block slide off the surface of the first rotating plate 32, which is more convenient to clean the debris on the surface of the first rotating plate 32. The tooth grooves 122 are provided with multiple teeth, so that the first rotating plate 32 can rotate multiple times and the first rotating plate 32 can be shaken multiple times, which has a better effect on cleaning the debris on the surface of the first rotating plate 32 and is more convenient to clean the debris in the dead corner. The width of the receiving box 31 is smaller than the width of the experimental chamber 2. At this time, there is a cavity on the front side of the receiving box 31, which is convenient for debris to fall on the front side of the receiving box 31, and there is no need to clean it after each measurement.The burden on staff is reduced, and the debris collection area is staggered with the test block test area, effectively preventing the collected debris from affecting the measurement.

[0036] like Figures 1 to 8 As shown, the first rotating plate 32 is slidably connected to a cylindrical block 344 inside, and the top of the cylindrical block 344 is rotatably connected to a ball 346. The top of the ball 346 is higher than the upper end of the first rotating plate 32, which facilitates the exposure of the ball 346 from the top of the first rotating plate 32. The pressing block is placed on the top of the first rotating plate 32. At this time, the pressing block is in contact with the ball 346. The mass of the pressing block is large. By converting the sliding friction between the pressing block and the first rotating plate 32 into rolling friction between the pressing block and the ball 346, it is convenient for the staff to move the test block and make the test block position adjustment more convenient. The interior of the accommodating box 31 is fixedly connected to the mounting block 34. The mounting block 34 The second movable groove 343 is provided inside to accommodate the movement of the cylindrical block 344, and the arc groove 341 is provided on the top rear side of the second movable groove 343 to accommodate the rotation of the cylindrical block 344. When the first rotating plate 32 rotates, the bottom of the cylindrical block 344 rotates inside the arc groove 341, so that when the first rotating plate 32 rotates to dump debris, the cylindrical block 344 will not affect the rotation of the first rotating plate 32, making the rotation of the first rotating plate 32 more convenient, and when large debris is tilted on the surface of the first rotating plate 32, the exposed balls 346 on the upper surface of the first rotating plate 32 make it easier for the debris to slide down, especially for cleaning large debris.

[0037] like Figures 1 to 8As shown, when the test block is placed on the top of the first rotating plate 32, the pressure plate 12 moves downward to squeeze the test block, and the first driving plate 121 moves inside the accommodating box 31. The interior of the first rotating plate 32 is slidably connected to the second driving plate 33. When the first driving plate 121 moves, the first driving plate 121 squeezes the second driving plate 33. The rear side of the second driving plate 33 and the contact surface with the first driving plate 121 are arc surfaces, which facilitates the arc surface of the second driving plate 33 to be squeezed by the first driving plate 121 and move. The position of the columnar block 344 corresponding to the interior of the driving plate 33 extends in the direction of the columnar block 344 to form an extension block 331. A limiting groove 345 is provided inside the columnar block 344 to accommodate the extension block 331. The limiting groove 345 restricts the extension block 331 so that the columnar block 344 can only move upward. When the test block moves on the surface of the first rotating plate 32, the test block squeezes the ball 346 without causing the ball 346 to move with the columnar block 344, making it more convenient for the test block to move on the surface of the first rotating plate 32. When the second driving plate 33 moves, the second driving plate 33 moves with the extension block 331, and the extension block 331 leaves the interior of the limiting groove 345. At this time, the column block 344 is not blocked by the extension block 331. At this time, the column block 344 can move inside the first rotating plate 32. The interior of the second driving plate 33 is provided with an arc-shaped extrusion block 332 at a position corresponding to the column block 344. The arc-shaped extrusion block 332 is an arc surface. During the movement of the second driving plate 33, the column block 344 and the ball 346 are squeezed. The cylindrical block 344 and the ball 346 are squeezed and move toward the mounting block 34, so that the ball 346 reaches the inside of the first rotating plate 32 from the upper surface of the first rotating plate 32, which facilitates the transition from the contact between the ball 346 and the test block to the contact between the first rotating plate 32 and the test block. When the test block is subsequently squeezed by the pressure plate 12, it will not be affected by the ball 346, so that the compression test of the test block is more accurate, and the pressure of the test block will not act on the ball 346, thereby avoiding damage to the ball 346 and making the device more convenient to use.

[0038] like Figures 1 to 8As shown, a first moving groove 324 is provided inside the first rotating plate 32 corresponding to the moving position of the second driving plate 33. The second driving plate 33 moves inside the first moving groove 324, which makes the movement of the second driving plate 33 more convenient. A first spring 325 welded to the second driving plate 33 is provided inside the first moving groove 324, so that the second driving plate 33 can return to its original position under the action of the first spring 325, making it more convenient for the second driving plate 33 to return to its original position. A fan-shaped groove 323 is provided on the surface of the first rotating plate 32 corresponding to the position of the ball 346. When the ball 346 is retracted into the interior of the mounting block 34, the second driving plate 33 blocks the original position of the ball 346 in the first rotating plate 32, which is used to prevent the surface of the first rotating plate 32 from being pressed. When the second driving plate 33 returns to its original position, the cylindrical block 344 and the ball bearing 346 are no longer blocked by the second driving plate 33, and the bottom of the cylindrical block 344 is provided with a second spring 342 welded to the mounting block 34, at this time, the second spring 342 squeezes the cylindrical block 344, so that the cylindrical block 344 returns to its original position, and blocks the debris on the surface of the first rotating plate 32 again. The top of the first rotating plate 32 is provided with a fan-shaped groove 323 corresponding to the position of the ball bearing 346. When the first rotating plate 32 rotates, it effectively prevents the ball bearing 346 from blocking small debris, and small debris enters the fan-shaped groove 323. When the first rotating plate 32 rotates, the debris entering the fan-shaped groove 323 can slide down, which has a better effect on cleaning debris.

[0039] like Figures 1 to 8As shown, the front bottom of the experimental chamber 2 is rotatably connected to the second flip door 22. When there are too many debris in the experimental chamber 2, the second flip door 22 is rotated to connect the experimental chamber 2 to the outside world, which is convenient for cleaning the debris. The top of the second flip door 22 is provided with a first flip door 21 rotatably connected to the experimental chamber 2. After the first flip door 21 is rotated, it is in the same plane with the first rotating plate 32. When the first flip door 21 is not in the same horizontal plane with the first rotating plate 32 after rotation, it indicates that the debris on the front side of the storage box 31 is too high and the debris needs to be cleaned. Rotate the first flip door 21 to open the first rotating plate 32. Door 21, after the first flip door 21 and the first rotating plate 32 are in the same horizontal plane, the front side of the first flip door 21 is slidably connected with a moving block 211. At this time, the moving block 211 is in a horizontal state. The opposite surfaces of the moving block 211 are fixedly connected to the limiting plate 212. The thickness of the limiting plate 212 is less than that of the moving block 211, preventing the limiting plate 212 from affecting the other two specifications of the test blocks, avoiding the test blocks from being difficult to put between the moving blocks 211, and placing the test blocks on the surface of the first flip door 21. The distance between the opposite surfaces of the moving block 211 is 150mm, standard The test piece with the size of 150mm×150mm×150mm cube and 150mm×300mm cylinder can be placed in the notch of the moving block 211, and then the moving block 211 is moved to move the moving block 211 with the test piece on the surface of the first flip door 21. Then the test piece leaves the surface of the first flip door 21. Since the first flip door 21 and the first rotating plate 32 are at the same horizontal plane, the test piece reaches the surface of the first rotating plate 32. When the moving block 211 can no longer push the test piece to move, the test piece is at the center position of the first rotating plate 32. , making it more convenient for the test block to reach the center position of the first rotating plate 32, reducing the steps of adjusting the test block on the surface of the first rotating plate 32, and an inclined groove 213 is provided on the opposite side of the limit plate 212. When the standard test piece size is a 100mm×100mm×100mm cube, it is only necessary to fit the two adjacent surfaces with the inclined groove 213. At this time, the moving block 211 can be pushed to move the test block to the surface of the first rotating plate 32, which is suitable for test blocks of different sizes, making the device more widely applicable, and reducing the need to adjust the test block when the test block is on the surface of the first rotating plate 32.
