Description

Technical Field

[0001] The utility model belongs to the technical field of concrete detection, and in particular relates to a concrete compressive strength detection device. Background Art

[0002] The compressive strength of concrete is an important indicator for measuring the quality of concrete. The current concrete compressive strength test basically applies a certain external force to the concrete specimen, records the load value of the concrete specimen during the compression process, and uses the ultimate load value obtained as an indicator for evaluating the compressive strength of concrete.

[0003] When the existing concrete compressive strength testing device is working, in order to prevent the concrete test block from sliding when under pressure, it is necessary to drive the fixing device separately and make the fixing device fix the concrete block on the testing table. This process makes the operation steps when testing the concrete block more cumbersome, thereby reducing the testing efficiency.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the present invention proposes a concrete compressive strength detection device to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a concrete compressive strength testing device, comprising a testing platform, a placement component is provided on the top of the testing platform, a fixing component is provided inside the placement component, a driving component is provided inside the testing platform, a driving end of the driving component is dynamically connected to the fixing component, a lifting detection component is provided on the top of the placement component, a linkage component is provided at the lifting end of the lifting detection component, and the lifting end of the linkage component is dynamically connected to the driving end of the driving component.

[0008] The driving component is used to drive the fixing component, the fixing component is used to fix the placement component and the concrete block inside the placement component, the lifting and detecting component is used to detect the concrete block, and the linkage component is used to make the lifting and detecting component and the driving component work synchronously.

[0009] Furthermore, the placement component includes a placement positioning groove, which is opened on the top of the detection table. A placement box is provided inside the placement positioning groove, and through grooves are opened on four sides of the inner wall of the placement box.

[0010] Further, the fixing component includes a U-shaped fixing plate, and there are multiple U-shaped fixing plates corresponding to the through grooves. The U-shaped fixing plates are movably connected to the through grooves, and an extrusion roller is provided on one side of the U-shaped fixing plate.

[0011] Further, the driving component includes a bidirectional screw rod. The bidirectional screw rod is rotatably connected to the inner wall of the inspection table. There are two bidirectional screw rods arranged vertically and staggered. A driving plate is threadedly connected to the outer surface of the bidirectional screw rod. The driving plate is fixedly connected to the corresponding U-shaped fixing plate. A fixing rod is fixedly connected to the inner wall of the inspection table corresponding to the bidirectional screw rod. The fixing rod is movably connected to the corresponding driving plate.

[0012] Further, the lifting and detecting component includes a lifting hydraulic cylinder. The lifting hydraulic cylinder is fixedly installed on the top of the inspection table. The output end of the lifting hydraulic cylinder is fixedly connected to a lifting plate. An installation seat is fixedly installed at the bottom of the lifting plate. A detecting device is fixedly installed at the bottom of the installation seat.

[0013] Further, the linkage component includes a gear. The gear is fixedly connected to the outer surface of the bidirectional screw rod. A tooth plate is meshed with the outer surface of the gear. The top end of the tooth plate penetrates through the inspection table and is fixedly connected to a T-shaped rod. The T-shaped rod is movably connected to the lifting plate. A spring is fixedly connected between the inner wall of the T-shaped rod and the bottom of the lifting plate.

[0014] Further, a guiding hole is opened at the bottom of the tooth plate. A guiding rod is fixedly connected to the inner wall of the bottom of the inspection table corresponding to the guiding hole. The guiding rod is movably connected to the guiding hole. A bearing column is fixedly connected inside the inspection table.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting the linkage component, when the lifting and detecting component descends, the lifting and detecting component can drive the driving component through the linkage component, so that the fixed end of the fixing component moves under the drive of the driving component and completes the fixation of the concrete block inside the placing component. Therefore, when performing the compressive strength test on the concrete block, it is only necessary to place the concrete block inside the placing component and then drive the lifting and detecting component. The whole operation step is relatively convenient, thus improving the efficiency of detecting the concrete block.

[0017] 2. By moving the placing box out of the placing positioning groove, it is convenient to clean the debris generated during the detection of the concrete block. At the same time, the U-shaped fixing plate can fix the placing box and the concrete block inside the placing box through the through groove, so that the stability of the placing box during use can also be ensured.

[0018] 3. After the present utility model fixes the concrete block through the C-shaped fixing plate, the lifting plate continues to move downward. At this time, the toothed plate cannot move under the restriction of the gear, while the lifting plate presses downward on the spring and enables the I-shaped rod to slide on the lifting plate. The above settings enable the C-shaped fixing plate to contact and fix the concrete block one step ahead of the detection device when detecting the concrete block, so that the stability of the concrete block can be guaranteed when the detection device detects the concrete block.

[0019] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the utility model.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the utility model.

[0032] Please refer to Figure 1-Figure 7 As shown, the present utility model is a device for detecting the compressive strength of concrete, including a detection table 1. A placing component 2 is arranged on the top of the detection table 1. A fixing component 3 is arranged inside the placing component 2. A driving component 4 is arranged inside the detection table 1. The driving end of the driving component 4 is power-connected to the fixing component 3. A lifting detection component 5 is arranged on the top of the placing component 2. The lifting end of the lifting detection component 5 is provided with a linkage component 6. The lifting end of the linkage component 6 is power-connected to the driving end of the driving component 4.

[0033] The driving component 4 is used to drive the fixing component 3. The fixing component 3 is used to fix the placing component 2 and the concrete block inside the placing component 2. The lifting detection component 5 is used to detect the concrete block. The linkage component 6 is used to make the lifting detection component 5 and the driving component work synchronously.

[0034] By placing the concrete block inside the placement component 2 and then driving the lifting detection component 5, the lifting detection component 5 moves downward. At the same time, while the lifting detection component 5 moves downward, it drives the driving component 4 through the linkage component 6, so that the driving component 4 drives the fixing component 3 and the fixing component 3 fixes the concrete block inside the placement component 2. After the fixing is completed, the lifting detection component 5 starts to extrude the fixed concrete block.

[0035] By setting the linkage component 6, when the lifting detection component 5 moves up and down, the lifting detection component 5 can drive the driving component 4 through the linkage component 6, so that the fixed end of the fixing component 3 moves under the drive of the driving component 4 and completes the fixation of the concrete block inside the placement component 2. Therefore, when performing the compressive strength test on the concrete block, it is only necessary to place the concrete block inside the placement component 2 and then drive the lifting detection component 5. The whole operation procedure is relatively convenient, thus improving the efficiency of detecting the concrete block.

[0036] In one embodiment, for the above-mentioned placement component 2, the placement component 2 includes a placement positioning groove 201 opened at the top of the detection table 1. A placement box 202 is arranged inside the placement positioning groove 201, and through grooves 203 are opened on the four sides of the inner wall of the placement box 202.

[0037] By placing the concrete block inside the placement box 202 and then carrying the placement box 202 through the through grooves 203 and placing the placement box 202 containing the concrete block into the placement positioning groove 201, the arrangement of the placement box 202 moved down from the detection table makes it convenient to clean the debris generated during the detection of the concrete block. The arrangement of the placement positioning groove 201 also makes it difficult for the fixed end of the fixing component 3 to be misaligned when fixing the concrete block.

[0038] In one embodiment, for the above-mentioned fixing component 3, the fixing component 3 includes a U-shaped fixing plate 301. There are multiple U-shaped fixing plates 301 corresponding to the through grooves 203, and the U-shaped fixing plates 301 are movably connected to the through grooves 203. An extrusion roller 302 is arranged on one side of the U-shaped fixing plate 301.

[0039] Two U-shaped fixing plates 301 that can move horizontally are in a group, and two U-shaped fixing plates 301 that can move vertically are in a group. When fixing the concrete blocks inside the placement box 202, the two groups of U-shaped fixing plates 301 move horizontally and vertically respectively, so that multiple U-shaped fixing plates 301 contact the sides of the corresponding concrete blocks and complete the fixing of the concrete blocks. The setting of the extrusion roller 302 enables that when a group of U-shaped fixing plates 301 first contacts the concrete block, the other group of U-shaped fixing plates 301 can normally push the concrete block, so that the fixed concrete block can be coaxial with the detection end of the lifting detection component 5.

[0040] In one embodiment, for the above-mentioned driving component 4, the driving component 4 includes a bidirectional screw 401. The bidirectional screw 401 is rotatably connected to the inner wall of the detection table 1. There are two bidirectional screws 401 arranged vertically and horizontally. A driving plate 402 is threadedly connected to the outer surface of the bidirectional screw 401. The driving plate 402 is fixedly connected to the corresponding U-shaped fixing plate 301. A fixing rod 403 is fixedly connected to the inner wall of the detection table 1 corresponding to the bidirectional screw 401. The fixing rod 403 is movably connected to the corresponding driving plate 402.

[0041] By driving the bidirectional screw 401, the bidirectional screw 401 can带动同一组的匚型固定板301同时向中间或者两侧进行移动,同时驱动板402可以在固定杆403的外表面进行滑动,从而使得驱动板402在双向螺杆401驱动下和固定杆403的限制下可以稳定地带动对应的匚型固定板301进行移动,而上下交错设置的两个双向螺杆401使得两组匚型固定板301在进行移动时不会出现碰撞的现象。

[0042] In one embodiment, for the above-mentioned lifting detection component 5, the lifting detection component 5 includes a lifting hydraulic cylinder 501. The lifting hydraulic cylinder 501 is fixedly installed on the top of the detection table 1. The output end of the lifting hydraulic cylinder 501 is fixedly connected to a lifting plate 502. A mounting seat 503 is fixedly installed at the bottom of the lifting plate 502. A detection device 504 is fixedly installed at the bottom of the mounting seat 503.

[0043] By driving the lifting hydraulic cylinder 501, the lifting hydraulic cylinder 501 can带动升降板502向下进行移动,而升降板502则通过安装座503带动检测装置504向下进行移动并对固定后的混凝土块进行挤压。

[0044] It should be noted that there are some inaccuracies in the original Chinese text that need to be corrected for a more accurate translation. For example, "带动同一组的匚型固定板301同时向中间或者两侧进行移动" and "带动升降板502向下进行移动" in the English translation should be more accurately expressed according to the context. The corrected translation is as follows: Two U-shaped fixing plates 301 that can move horizontally are grouped together, and two U-shaped fixing plates 301 that can move vertically are grouped together. When fixing the concrete blocks inside the placement box 202, the two groups of U-shaped fixing plates 301 move horizontally and vertically respectively, so that multiple U-shaped fixing plates 301 contact the sides of the corresponding concrete blocks and complete the fixing of the concrete blocks. The setting of the extrusion roller 302 enables that when a group of U-shaped fixing plates 301 first contacts the concrete block, the other group of U-shaped fixing plates 301 can normally push the concrete block, so that the fixed concrete block can be coaxial with the detection end of the lifting detection component 5.

[0040] In one embodiment, for the above-mentioned driving component 4, the driving component 4 includes a bidirectional screw 401. The bidirectional screw 401 is rotatably connected to the inner wall of the detection table 1. There are two bidirectional screws 401 arranged vertically and horizontally. A driving plate 402 is threadedly connected to the outer surface of the bidirectional screw 401. The driving plate 402 is fixedly connected to the corresponding U-shaped fixing plate 301. A fixing rod 403 is fixedly connected to the inner wall of the detection table 1 corresponding to the bidirectional screw 401. The fixing rod 403 is movably connected to the corresponding driving plate 402.

[0041] By driving the bidirectional screw 401, the bidirectional screw 401 can drive the U-shaped fixing plates 301 in the same group to move towards the middle or both sides simultaneously. At the same time, the driving plate 402 can slide on the outer surface of the fixing rod 403, so that the driving plate 402 can stably drive the corresponding U-shaped fixing plates 301 to move under the drive of the bidirectional screw 401 and the restriction of the fixing rod 403. The two vertically and horizontally staggered bidirectional screws 401 prevent the two groups of U-shaped fixing plates 301 from colliding when moving.

[0042] In one embodiment, for the above-mentioned lifting detection component 5, the lifting detection component 5 includes a lifting hydraulic cylinder 501. The lifting hydraulic cylinder 501 is fixedly installed on the top of the detection table 1. The output end of the lifting hydraulic cylinder 501 is fixedly connected to a lifting plate 502. A mounting seat 503 is fixedly installed at the bottom of the lifting plate 502. A detection device 504 is fixedly installed at the bottom of the mounting seat 503.

[0043] By driving the lifting hydraulic cylinder 501, the lifting hydraulic cylinder 501 can drive the lifting plate 502 to move downward, and the lifting plate 502 can drive the detection device 504 to move downward through the mounting seat 503 and extrude the fixed concrete block.

[0044] In one embodiment, for the above-mentioned linkage component 6, the linkage component 6 includes a gear 601, the gear 601 is fixedly connected to the outer surface of the bidirectional screw 401, a toothed plate 602 is meshed with the outer surface of the gear 601, the top end of the toothed plate 602 penetrates through the detection table 1 and is fixedly connected to a T-shaped rod 603, the T-shaped rod 603 is movably connected to the lifting plate 502, and a spring 604 is fixedly connected between the inner wall of the T-shaped rod 603 and the bottom of the lifting plate 502.

[0045] When the lifting plate 502 moves downward, it drives the toothed plate 602 to move downward through the T-shaped rod 603 and the spring 604, so that the toothed plate 602 can drive the bidirectional screw 401 to rotate through the gear 601 during the moving process. When the U-shaped fixing plate 301 on the bidirectional screw 401 completes the clamping and fixing of the concrete block, the lifting plate 502 continues to move downward. At this time, the toothed plate 602 cannot move under the restriction of the gear 601, and the lifting plate 502 can squeeze the spring 604 downward at this time and make the T-shaped rod 603 slide on the lifting plate 502. The above setting enables the U-shaped fixing plate 301 to contact and fix the concrete block one step ahead of the detection device 504 when detecting the concrete block, so that the stability of the concrete block can be guaranteed when the detection device 504 detects the concrete block.

[0046] In one embodiment, for the above-mentioned toothed plate 602, a guide hole 7 is formed at the bottom of the toothed plate 602, a guide rod 8 is fixedly connected to the bottom of the inner wall of the detection table 1 corresponding to the guide hole , the guide rod 8 is movably connected to the guide hole 7, and a bearing column 9 is fixedly connected to the inside of the detection table 1.

[0047] When the toothed plate 602 moves, the guide rod 8 can move inside the guide hole 7. This setting ensures the stability of the toothed plate 602 during movement, and the setting of the bearing column 9 prevents the inside of the detection table 1 from collapsing easily due to excessive pressure when the detection device 504 squeezes and detects the concrete block.

[0048] Through the above technical solutions: 1. By setting the linkage component 6, when the lifting detection component 5 moves downward, the lifting detection component 5 can drive the driving component 4 through the linkage component 6, so that the fixed end of the fixing component 3 moves under the drive of the driving component 4 and completes the fixation of the concrete block inside the placing component 2. Therefore, when performing the compressive strength test on the concrete block, it is only necessary to place the concrete block inside the placing component 2 and then drive the lifting detection component 5. The whole operation steps are relatively convenient, thus improving the efficiency of testing the concrete block; 2. By moving the placing box 202 out of the placing positioning groove 201, it is more convenient to clean the debris generated during the testing of the concrete block. At the same time, the U-shaped fixing plate 301 can fix the placing box 202 and the concrete block inside the placing box 202 through the through groove 203, so that the stability of the placing box 202 during use can also be ensured; 3. After the U-shaped fixing plate 301 completes the fixation of the concrete block, the lifting plate 502 continues to move downward. At this time, the toothed plate 602 cannot move under the restriction of the gear 601, and the lifting plate 502 presses downward on the spring 604 and makes the I-shaped rod 603 slide on the lifting plate 502. The above settings make it possible that when testing the concrete block, the U-shaped fixing plate 301 can contact and fix the concrete block one step ahead of the testing device 504, so that the stability of the concrete block can be ensured when the testing device 504 tests the concrete block.
