Description

Technical Field

[0001] This invention relates to the field of concrete compressive strength testing, specifically to a concrete compressive strength testing device. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, when necessary, admixtures and additives in a certain proportion, uniformly mixing, compacting, and curing. During the production process, many factors can affect the quality of concrete. Substandard concrete can directly or indirectly threaten the personal safety of citizens. Therefore, testing the quality of concrete is essential, and compressive strength is one of the most important technical indicators for testing the quality of concrete.

[0003] Concrete compressive strength testing is an essential part of concrete strength testing. Concrete compressive strength testing instruments usually consist of a testing platform and a pressure application mechanism.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] Example 1

[0031] See Figures 1-10 A concrete compressive strength testing device includes a testing platform 1, a support frame 2 mounted on the testing platform 1, a pressure applying mechanism 3 for compressive strength testing mounted on the support frame 2, a positioning plate 4 movably mounted on the testing platform 1, and a first discharge box 5 and a second discharge box 6 for placing concrete on the positioning plate 4. The device also includes: The detection switching mechanism is installed at the connection between the positioning plate 4 and the detection platform 1. It is used to drive the concrete on the first discharge box 5 and the second discharge box 6 to perform directional switching detection. The detection switching mechanism includes a transmission plate 24 for driving the positioning plate 4 to perform positioning movement switching. The transmission plate 24 is fixedly installed on one side of the dovetail slider 23. The dovetail slider 23 is limited and slidably connected to the inside of the detection platform 1. A first sector gear 21 is provided on one side of the transmission plate 24 and meshes with it. A second sector gear 22 is provided on the other side of the transmission plate 24 and meshes with it.

[0032] Furthermore, the detection switching mechanism also includes a guide platform 25 for driving the dovetail slider 23 to move in a guiding manner. The guide platform 25 is fixedly installed inside the detection platform 1. The dovetail slider 23 is limited and slidably connected inside the guide platform 25. The guide platform 25 is provided with a dovetail groove 26 that is adapted to slide and connect with the dovetail slider 23. Both sides of the transmission plate 24 are provided with first teeth 33 that mesh with the first sector gear 21 and the second sector gear 22.

[0033] Furthermore, the detection switching mechanism also includes a third rotating gear 28 for driving the first sector gear 21 and the second sector gear 22 to rotate synchronously. The first sector gear 21 and the second sector gear 22 are both fixedly mounted on the second connecting shaft 19 via the third connecting shaft 20. The second connecting shaft 19 is rotatably mounted on the detection table 1. One end of the second connecting shaft 19 is fixedly connected to the second rotating gear 27. The third rotating gear 28 is meshed with the second rotating gear 27. The third rotating gear 28 is rotatably mounted inside the detection table 1 via the fourth connecting shaft 29.

[0034] Furthermore, the detection switching mechanism also includes a drive motor 32 for driving the third rotating gear 28 to rotate, a worm gear 30 fixedly connected to the fourth connecting shaft 29, a worm 31 meshing with the worm gear 30, the worm 31 fixedly connected to the output shaft of the drive motor 32, and the drive motor 32 fixedly installed inside the detection table 1.

[0035] Preferably, when testing the compressive strength of concrete, the pressure-applying mechanism 3 on the support frame 2 controls the pressure intensity. The first discharge box 5 and the second discharge box 6 can respectively receive concrete. Whenever the compressive strength test of the first discharge box 5 is completed, the second discharge box 6 is pre-filled with an appropriate amount of concrete to facilitate the unloading process at the first discharge box 5.

[0036] When switching processing is required for testing, the output shaft of the drive motor 32 drives the worm 31 to rotate. Under the meshing connection between the worm 31 and the worm wheel 30, the third rotating gear 28 on the fourth connecting shaft 29 rotates. Under the meshing connection between the third rotating gear 28 and the second rotating gear 27, the first sector gear 21 and the second sector gear 22 on the second connecting shaft 19 rotate. Since the first sector gear 21 and the second sector gear 22 rotate in the same direction, when the first sector gear 21 meshes with the dovetail slider 23, the second sector gear 22 is just disengaged from the position where it meshes with the dovetail slider 23. And when the second sector gear 22 meshes with the dovetail slider 23, the first sector gear 21 is just disengaged from the position where it meshes with the dovetail slider 23. Thus, the switching movement control processing of the first material box 5 and the second material box 6 on the positioning plate 4 can be well realized, which facilitates the testing of the compressive strength of concrete and significantly improves the testing efficiency.

[0037] Traditional strength testing methods are not convenient for quickly unloading and replacing samples. This application, through its testing switching mechanism, can quickly switch between testing and replacing concrete samples without stopping the machine to change fixtures. It has high adaptability and facilitates continuous data acquisition. That is, when testing is being performed at the first discharge box 5, unloading and loading can be performed at the second discharge box 6 accordingly. This significantly improves work efficiency, reduces maintenance costs, and facilitates testing.

[0038] Example 2

[0039] like Figures 1 to 7 As shown, this embodiment, based on embodiment 1, also includes a positioning mechanism, which is installed on the testing platform 1 and is used to drive the concrete on the first discharge box 5 or the second discharge box 6 to perform positioning processing. The positioning mechanism includes a material pusher plate 13 for squeezing and fixing the inside of the first discharge box 5 or the second discharge box 6. The material pusher plate 13 is squeezed and controlled by the rotation of the outer eccentric drive wheel 18.

[0040] Furthermore, the positioning mechanism also includes a pressing plate 15 for driving the material pusher plate 13 to move and connect. The material pusher plate 13 is fixedly connected to the pressing plate 15 via a slide rod 14. The slide rod 14 is limited and slidably connected to the first material box 5 and the second material box 6. An arc-shaped side 16 for guidance is provided on the side of the pressing plate 15.

[0041] Furthermore, a reset spring 17 is provided at the connection between the pressing plate 15 and the first feeding box 5 or the second feeding box 6, and an eccentric drive wheel 18 is rotatably connected to one side of the pressing plate 15, and the eccentric drive wheel 18 is fixedly installed on the second connecting shaft 19.

[0042] Preferably, in this embodiment, whenever the first discharge box 5 or the second discharge box 6 moves to the position directly below the pressure mechanism 3, the detection switching mechanism synchronously drives the eccentric drive wheel 18 on the second connecting shaft 19 to rotate to the maximum docking position. Under the eccentric action of the eccentric drive wheel 18, the sliding rod 14 connected to the pressing plate 15 is driven to move closer to each other, thereby completing the docking movement of the whole material push plate 13 and realizing the positioning of the concrete. This facilitates the strength detection of the pressure mechanism 3 above. When the first discharge box 5 or the second discharge box 6 moves away from the pressure mechanism 3, under the eccentric rotation of the eccentric drive wheel 18 and the elastic reset action of the return spring 17, the whole material push plate 13 automatically moves away from each other, thereby facilitating the subsequent unloading process.

[0043] By moving the first discharge box 5 and the second discharge box 6, the integration and positioning of the concrete by the whole material pusher 13 is completed automatically. No manual intervention is required for positioning, eliminating the risk of manual operation and significantly improving the safety of operation. At the same time, this real-time switching processing method realizes the real-time connection of the testing process and improves the continuity of the overall testing.

[0044] It should be noted that the side of the pressing plate 15 is provided with an arc-shaped side 16, which facilitates the contact and driving of the eccentric drive wheel 18.

[0045] Example 3

[0046] like Figures 1 to 7 As shown, this embodiment, based on the above embodiment, also includes a unloading mechanism, which is installed at the connection between the positioning plate 4 and the detection platform 1, and is used to drive the concrete on the first discharge box 5 or the second discharge box 6 to unload. The unloading mechanism includes a mechanism for driving the first sealing door 7 on the first discharge box 5 or the second sealing door 8 on the second discharge box 6 to perform a flipping unloading process. The first sealing door 7 and the second sealing door 8 are both flipped by the movement of the positioning plate 4.

[0047] Furthermore, the unloading mechanism also includes a toothed plate 11 for driving the first sealing door 7 or the second sealing door 8 to flip. The toothed plate 11 is fixedly installed on the detection table 1 by a fixing plate 12, and the positioning plate 4 is slidably connected to the toothed plate 11. The first sealing door 7 and the second sealing door 8 are rotatably connected by a first connecting shaft 9. A first rotating gear 10 is fixedly connected to the first connecting shaft 9, and the toothed plate 11 is provided with a plurality of second teeth 34 that mesh with the first rotating gear 10.

[0048] Preferably, in this embodiment, whenever the first discharge box 5 or the second discharge box 6 moves to the maximum position away from the pressure mechanism 3, the first connecting shaft 9 on the first rotating gear 10 is driven to rotate under the meshing transmission action of the second tooth 34 on the toothed plate 11. Thus, the first connecting shaft 9 synchronously drives the first sealing door 7 on the first discharge box 5 or the second sealing door 8 on the second discharge box 6 to be flipped and flattened, thereby facilitating the subsequent unloading process and further improving the subsequent detection efficiency.

[0049] Whenever the first discharge box 5 or the second discharge box 6 moves to the maximum position away from the pressure mechanism 3, the automatic flipping and flattening design of the first sealing door 7 and the second sealing door 8 can realize rapid unloading, greatly improve the turnaround efficiency of batch testing, and simultaneously improve operational safety. In addition, this cleaning method can more thoroughly clean the residue at the bottom of the first discharge box 5 and the second discharge box 6, thereby facilitating the placement of subsequent samples and significantly improving work efficiency.

[0050] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
