Description

Technical Field

[0001] The invention relates to the technical field of concrete strength detection, in particular to an all-round concrete compressive strength detection device. Background Art

[0002] Concrete compressive strength testing is the core link of concrete quality control, which is crucial to ensure the safety, reliability and durability of the structure. The tester will place the concrete test block to be tested on the pressure testing machine. The pressure component on the top of the pressure testing machine will apply a compressive force downward. Under the specified pressure, if the concrete test block does not break, it means that the concrete test block meets the compressive strength standard. Otherwise, it means that the compressive strength of the concrete test block is unqualified.

[0003] When testing concrete test blocks, it is usually necessary to decide whether to perform compressive tests on different sides of the test block based on relevant standards or test specifications. The pressure application direction of the pressure testing machine is from top to bottom, that is, there is only one direction. Therefore, the testers need to manually turn the concrete test blocks over. For the compressive strength of concrete in multiple directions, the testers need to turn the concrete blocks over multiple times, which undoubtedly causes inconvenience in the current concrete compressive strength testing. In addition, the concrete test blocks may crack during the turning process due to the sudden release of their own residual stress, causing injuries to the testers. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7 As shown, the present invention includes the following embodiments: Embodiment 1: An all-round concrete compressive strength testing device, comprising a base 1 and a top base 2 supported by a support column 11 on the upper surface of the base 1; a rotating groove 12 is arranged at the center of the upper surface of the base 1; a rotating disc 3 is rotatably sealed in the rotating groove 12; the center of the lower surface of the rotating disc 3 is driven by a first motor 31; a left detection seat 4 and a right detection seat 5 are symmetrically arranged on the upper surface of the base 1 about the rotating groove 12; a left driven groove 41 is arranged on the side of the left detection seat 4 facing the center of the rotating disc 3; a left active groove 42 connected to the left driven groove 41 is arranged on the upper surface of the left detection seat 4; The active groove 42 is connected to the left active block 43 by sliding up and down; the left active block 43 is provided with a left main surface 431 inclined toward the turntable 3 at the lower end; the left driven groove 41 is connected to the left driven block 44 by horizontal sliding; the left driven block 44 is provided with a left slave surface 441 which is inclined with the left main surface 431 at one end away from the center of the turntable 3; the width of the left active block 43 in the front-to-back direction is smaller than the width of the left driven block 44 in the front-to-back direction; the left slave surface 441 is connected to the groove wall of the left active groove 42 by a left tension spring 45; the top seat 2 is connected to the hydraulic cylinder 6 with a pressure head 61 by sliding in the left-right direction.

[0023] In this embodiment, the top seat 2 is penetrated by a main top groove 21 from top to bottom; the main top groove 21 is penetrated by a secondary top groove 22 from front to back; the main top groove 21 and the secondary top groove 22 are slidably connected to the top block 23 in the left and right directions; the hydraulic cylinder 6 is penetrated by and fixed to the top block 23 from top to bottom; the output shaft of the hydraulic cylinder 6 is lower and fixed to the pressure head 61; the secondary top groove 22 is laterally rotationally connected to the sliding rod 24 and the second screw 25; the top block 23 is slidably connected to the sliding rod 24, and the top block 23 is threadedly connected to the second screw 25; the end of the second screw 25 is fixedly connected to the second motor 26; the rotation of the second motor 26 can drive the top block 23 to slide laterally.

[0024] During operation, the hydraulic cylinder 6 in the initial state is located directly above the turntable 3. After the test personnel place the concrete test block at the center of the turntable 3, the concrete test block is located directly below the pressure head 61. The hydraulic cylinder 6 is then started to extend and drive the pressure head 61 to move downward. During the downward movement of the pressure head 61, it will move closer to the turntable 3, and the pressure head 61 will eventually fall on the upper surface of the concrete test block. Then the hydraulic cylinder 6 will continue to apply pressure. If the concrete test block is damaged under the specified pressure, it means that the concrete test block is unqualified. The concrete test block can be directly removed. The undamaged concrete test block will undergo a compressive strength test in the next direction. Specifically, the hydraulic cylinder 6 is shortened to drive the pressure head 61 to move upward. The pressure head 61 moves up and stops after it is higher than the upper end of the left active block 43. Then the second motor 26 rotates The rotating second motor 26 will drive the second screw 25 to rotate. During the rotation of the second screw 25, the top block 23 will be driven to slide along the main top groove 21, the auxiliary top groove 22 and the slide bar 24. The top block 23 will drive the hydraulic cylinder 6 and the pressure head 61 to move toward the left side until the pressure head 61 moves to the top of the left active block 43 and stops. Then the hydraulic cylinder 6 extends and drives the pressure head 61 to move downward. During the downward movement of the pressure head 61, it will contact the upper end of the left active block 43. During the downward movement of the pressure head 61, the left active block 43 will be squeezed to move downward along the left active groove 42. During the downward movement of the left active block 43, the left main surface 431 will be driven to squeeze the left slave surface 441. Under the inclined plane transmission, the left active block 43 will transmit force to the left driven block 44. Due to the force applied by the left driven block 44 It is the component force of the force applied by the left active block 43 moving downward, so the pressure head 61 will appropriately increase the downward pressure to ensure that the force applied by the left driven block 44 on the concrete test block reaches the standard value. The left follower surface 441 on the left driven block 44 will slide along the left driven groove 41 after being compressed, and the left driven block 44 will overcome the left tension spring 45 and move close to the concrete test block. The left driven block 44 will squeeze the concrete test block, and the concrete test block will approach the right detection seat 5 under the compression of the left driven block 44. The right detection seat 5 provides support for the right side of the concrete test block. The left driven block 44 will transfer the pressure from left to right to the concrete test block. The material of the left detection seat 4, the left active block 43 and the right active block 53 is consistent with that of the pressure head 61, that is, metal, which can ensure the strength of the components, so that the concrete test The block can stably withstand the lateral force. When the left follower block 44 applies the corresponding pressure, the concrete test block is damaged, indicating that it is unqualified. The damaged concrete test block can be directly removed. If the concrete test block is not damaged, it is qualified. In this way, the compression test in the next direction is carried out. Specifically, the hydraulic cylinder 6 is controlled to shorten. The hydraulic cylinder 6 will drive the pressure head 61 to move up and disengage from the left active block 43. The left tension spring 45 will pull the left follower block 44 away from the right detection seat 5. The left follower block 44 will be out of contact with the concrete test block and retract to the left follower groove 41. In the process of the left follower block 44 moving away from the right detection seat 5, the left follower surface 441 will be driven to squeeze the left main surface 431. Under the inclined plane transmission, the left active block 43 moves up and slides along the left active groove 42.The upper end of the left active block 43 extends out of the upper end of the left active slot 42 again. After the left driven block 44 moves away from the concrete test block, space is reserved for the concrete test block to change its surface. Then the first motor 31 rotates, and the rotating first motor 31 drives the turntable 3 to rotate in the turntable 12. During the rotation of the turntable 3, the concrete test block on the upper surface is driven to rotate until the surface of the concrete test block in the last direction faces the left detection seat 4. After the concrete test block is turned over, the hydraulic cylinder 6 extends to drive the pressure head 61 to move downward. During the downward movement of the pressure head 61, the left active block 43 is squeezed, and the left driven block 44 is driven to extend out of the left driven slot 41 again under the inclined plane transmission. The left follower block 44 squeezes the concrete test block again. Similarly, if the concrete test block is damaged under the specified pressure, it means that the concrete test block is unqualified and the concrete test block can be directly removed. If the concrete test block is not damaged under the specified pressure, it means that the concrete test block is qualified. After the compressive strength test of the concrete test block is completed in three directions, the hydraulic cylinder 6 shortens and drives the pressure head 61 to move upward. The left follower block 44 returns to the left follower groove 41 under the pull of the left tension spring 45. The second motor 26 drives the second screw 25 to rotate, so that the hydraulic cylinder 6 returns to the center of the turntable 3, realizing a full range of compressive strength testing. Finally, the qualified concrete test block can be removed. The present invention uses the inclined plane transmission between the left active block 43 and the left driven block 44 in the left testing seat 4, so that the pressure head 61 on the hydraulic cylinder 6 can transmit the force in the vertical direction to the horizontal direction, and cooperate with the rotation of the turntable 3 to realize the compressive strength test of the concrete test block in three directions, without the need for the tester to turn over the concrete test block, which greatly improves the safety and convenience of concrete compressive strength test.

[0025] Embodiment 2: The right detection seat 5 is provided with a right driven groove 51 on the side facing the center of the turntable 3; the upper surface of the right detection seat 5 is provided with a right active groove 52 connected with the right driven groove 51; the right active groove 52 is connected to the right active block 53 by sliding up and down; the right active block 53 is provided with a right main surface 531 inclined toward the turntable 3 at the lower end; the right driven groove 51 is connected to the right driven block 54 by horizontal sliding; the right driven block 54 is provided with a right follower surface 541 which is inclinedly transmitted with the right main surface 531 at the end away from the center of the turntable 3; the width of the right active block 53 in the front-to-back direction is smaller than the width of the right driven block 54 in the front-to-back direction; the right follower surface 541 is connected to the groove wall of the right active groove 52 by a right tension spring 55.

[0026] In this embodiment, the support column 11 is connected to the connecting plate 7 by sliding up and down; the connecting plate 7 is located between the pressure head 61 and the left detection seat 4 in the vertical direction; a avoidance hole 71 is provided through the center of the connecting plate 7; the avoidance hole 71 is located directly above the center of the turntable 3; the left active block 43 and the right active block 53 have the same specifications, and the left driven block 44 and the right active block 53 have the same specifications; the left detection seat 4 and the right detection seat 5 have the same specifications.

[0027] During operation, the test personnel place the test block on the upper surface of the turntable 3 near the center, and the hydraulic cylinder 6 moves sideways on the top seat 2. The hydraulic cylinder 6 drives the pressure head 61 to stagger with the avoidance hole 71, and then the hydraulic cylinder 6 drives the pressure head 61 to move downward to squeeze the connecting plate 7. During the downward movement of the connecting plate 7, it slides and moves downward along the support column 11. The connecting plate 7 squeezes the left active block 43 and the right active block 53 at the same time. The upper end of the left active block 43 is squeezed by the connecting plate 7 and slides and moves downward along the left active groove 42. When the left active block 43 moves, the left driven block 44 overcomes the left tension spring 45 and moves close to the center of the turntable 3. Similarly, the upper end of the right active block 53 is squeezed by the connecting plate 7 and slides along the right active groove 52 during the downward movement. The right main surface 531 of the lower end of the right active block 53 squeezes the right slave surface 541. In this way, under the inclined transmission, the right driven block 54 moves close to the center of the turntable 3 along the right driven groove 51, overcoming the right tension spring 55. The left driven block 44 and the right driven block 54 move close to each other and push the concrete test block, so that The concrete test block is located at the center of the turntable 3 in the left and right directions, and then the hydraulic cylinder 6 drives the pressure head 61 to move upward, and the left tension spring 45 pulls the left follower block 44 away from the concrete test block and retracts it to the left follower groove 41, and the right tension spring 55 pulls the right follower block 54 away from the concrete test block and retracts it to the right follower groove 51, thus reserving space for the rotation of the concrete test block, and then the first motor 31 drives the turntable 3 to rotate 90 degrees in the rotating groove 12, and when the turntable 3 rotates 90 degrees, the concrete test block on the upper surface will be driven to rotate 90 degrees, and then The pressure head 61 is controlled to move downward to squeeze the connecting plate 7 and move downward again. The downward movement of the connecting plate 7 will make the left driven block 44 and the right driven block 54 approach each other and push the concrete test block, so that the position of the concrete test block in the left and right directions is adjusted again, so that the position of the concrete test block is accurately adjusted to the center position of the turntable 3, and the position of the concrete test block is also accurately adjusted to the position directly below the pressure head 61. Compared with manual placement, the placement error is greatly reduced, so that the accuracy of concrete compressive strength testing is further improved; After the position adjustment of the concrete test block is completed, the hydraulic cylinder 6 will move laterally along the top seat 2, so that the hydraulic cylinder 6 drives the pressure head 61 to move to just above the avoidance hole 71, and then the hydraulic cylinder 6 will drive the pressure head 61 to move downward through the avoidance hole 71 to squeeze the concrete test block, so as to realize the detection of one direction of the concrete test block. After completing the detection of this direction, the hydraulic cylinder 6 will drive the pressure head 61 to move upward above the connecting plate 7. As the hydraulic cylinder 6 is controlled to drive the pressure head 61 to stagger with the avoidance hole 71, the hydraulic cylinder 6 is then controlled to drive the pressure head 61 to transfer the pressure to the connecting plate 7. The connecting plate 7 will move downward under pressure, driving the left follower block 44 and the right follower block 54 to move closer to each other. 44 and the right follower block 54 will perform an extrusion test on the concrete test block. After the test is completed, after the pressure head 61 moves up, the left follower block 44 and the right follower block 54 will move away from each other. How to detect that the concrete test block is always located at the center of the upper surface of the turntable 3, so that the concrete test block can smoothly change the surface under the rotation of the turntable 3, avoiding the situation that the concrete test block is eccentric on the upper surface of the turntable 3 and affects the surface change. After the surface change is completed, the pressure head 61 moves down again, and the left follower block 44 and the right follower block 54 are close to each other again, so that the compressive strength of the concrete test block in three directions is tested. After the test is completed, the pressure head 61 moves up and moves laterally to just above the avoidance hole 71; In this embodiment, the left follower block 44 and the right follower block 54 are simultaneously moved close to each other to squeeze the concrete test block, so that the concrete test block after testing is located at the center of the turntable 3, thereby making the subsequent concrete test block surface change smoother, ensuring the smooth progress of the concrete compressive strength test.

The threads at both ends of the first screw 16 are opposite, so during the rotation of the first screw 16, the two sliders 14 will be driven to move closer to or away from each other, and the sliders 14 will slide in their respective slide grooves 13, so that the left test seat 4 and the right test seat 5 are moved closer to or away from each other, because the second tooth 72 is out of contact with the first tooth 532 after the connecting plate 7 moves up. , so that the left detection seat 4 and the right detection seat 5 can move freely along the side under control, and when the left detection seat 4 and the right detection seat 5 are close to each other, the detection equipment can detect concrete test blocks with smaller specifications, and when the left detection seat 4 and the right detection seat 5 are far away from each other, the detection equipment can detect concrete test blocks with larger specifications; after completing the movement adjustment of the left detection seat 4 and the right detection seat 5, the detection personnel will insert the crank handle 191 into the clamping hole 111 along the crank hole 192 to lock the crank plate 19. After the crank plate 19 is locked, the worm 18 will be locked. Under normal conditions, the worm 18 can only drive the worm wheel 17 to move, and the worm wheel 17 cannot drive the worm 18 to move. Therefore, in order to adjust the distance between the left detection seat 4 and the right detection seat 5, only the movement of the worm 18 can be controlled. Since the worm 18 is locked, the positions of the left detection seat 4 and the right detection seat 5 are locked; After the position adjustment of the left detection seat 4 and the right detection seat 5 is completed, the pressure head 61 moves downward with the drive of the hydraulic cylinder 6, and the pressure head 61 will squeeze the connecting plate 7 to move downward. During the downward movement of the connecting plate 7, it will overcome the elastic force of the spring 73 and move downward. During the downward movement of the connecting plate 7, the second tooth 72 will be driven to contact the first tooth 532, so that the left active block 43 and the right active block 53 are locked in the lateral direction at the upper end, and the left detection seat 4 and the right detection seat 5 are locked at the lower end, thereby improving the strength of the left detection seat 4 and the right detection seat 5, making the compressive strength test of the concrete test block in the horizontal direction more stable; after the concrete test block test is completed, the pressure head 61 moves up, the spring 73 will push the connecting plate 7 to move upward, and the second tooth 72 will be separated from the contact with the first tooth 532 after the connecting plate 7 moves upward, so that the left detection seat 4 and the right detection seat 5 can be driven with the rotation of the first screw 16.

[0033] Embodiment 4: A pressure plate 8 is provided on the side where the left follower block 44 and the right follower block 54 are close to each other; a wedge-shaped groove 81 is provided through the front and back of the side where the two pressure plates 8 are away from each other; a wedge block 82 is fixedly connected to the end where the left follower block 44 and the right follower block 54 are close to each other; the wedge block 82 is slidably connected to the corresponding wedge-shaped groove 81.

[0034] In this embodiment, a slot 83 is provided through the upper inner wall of the wedge-shaped groove 81; a notch 84 is provided on the upper outer wall of the wedge-shaped block 82 at a position corresponding to the slot 83; an insert block 85 is connected to the slot 83 for up and down sliding movement; and the lower end of the insert block 85 can be inserted into the notch 84.

[0035] During operation, the left follower block 44 and the right follower block 54 will move closer to each other under the drive, and the left follower block 44 and the right follower block 54 will drive the corresponding pressure plate 8 to move, so that the two pressure plates 8 are close to each other, and the pressure plate 8 increases the detection range of the concrete pressure blocks, so that concrete pressure blocks of different specifications can be contacted and squeezed by the pressure plate 8; when the pressure plate 8 is damaged, the staff will lift the plug block 85 upwards, and after the plug block 85 moves up, the lower end of the plug block 85 will be moved out of the missing groove 84, so that the wedge block 82 and the wedge groove 81 are unlocked, and the pressure plate 8 can be controlled to move forward and backward to achieve the separation of the pressure plate 8 and the wedge block 82. After replacing the new pressure plate 8, the plug block 85 is inserted into the slot 83 and the missing groove 84 to complete the locking of the pressure plate 8 and the wedge block 82, and the lower edge of the pressure plate 8 contacts the upper surface of the turntable 3.

[0036] The present invention is all-round, which means that the strength of the concrete test block can be tested in three directions, that is, the compressive strength test can be carried out in all directions; the parts of the present invention are all made of metal, so the force transmission can be achieved while ensuring the strength, thus meeting the testing requirements.
