[0007] As a preferred embodiment, the system also includes a hopper installed on the open test block box, the hopper comprising a horizontal section and an inclined section, the inner bottom wall of the horizontal section being flush with the top of the open test block box.
[0008] As a preferred embodiment, a pusher plate is slidably installed at the horizontal part of the hopper, and a pushing component is installed on the detection platform to provide power for the sliding of the pusher plate; furthermore, the width of the pusher plate matches the width of the horizontal part of the hopper, and the pushing component is preferably a telescopic cylinder, but the pushing component can also be a linear motor or other equivalent components that drive the pusher plate to slide.

[0014] Compared with the prior art, this utility model provides a concrete strength testing device with the following advantages: The device places the concrete specimen to be tested on a pallet, activates a pressure cylinder, extends the output end of the pressure cylinder, and presses the concrete specimen into an open specimen box until the specimen is completely inside and the pallet can no longer move down to the bottom of the box. As the output end of the pressure cylinder continues to extend, the pressure cylinder continues to move down until the concrete specimen is crushed. The maximum pressure value is detected by a pressure detector, yielding the compressive strength limit of the concrete specimen. The open specimen box effectively prevents debris from scattering, making it safer. Furthermore, the open specimen box concentrates the debris, facilitating subsequent cleaning.

The slide rod 4 is slidably installed on the open test block box 2 and the testing platform 1. One end of the spring 5 abuts against the bottom of the support plate 3, and the other end of the spring 5 abuts against the inner bottom wall of the open test block box 2. The pressure testing component includes a mounting frame 6 fixedly installed on the testing platform 1, a pressure cylinder 7 fixedly installed on the mounting frame 6, a pressure detector 8 installed at the output end of the pressure cylinder 7, and a pressure mold 9 installed below the pressure detector 8. The pressure mold 9 is located directly above the open test block box 2. Furthermore, the bottom wall of the open test block box 2 and the testing table 1 are both provided with openings that allow the sliding rod 4 to pass through, and the sliding rod 4 is slidably installed in the openings; the spring 5 is in its naturally extended state, and the top of the support plate 3 is flush with the top of the open test block box 2; the external dimensions of the mold 9 are smaller than the internal dimensions of the open test block box 2, and there is a gap of at least 5cm between the outer wall of the concrete test block to be tested and the corresponding inner wall of the open test block box 2, and the cross-sectional area of the mold 9 is the same as the cross-sectional area of the concrete test block to be tested.
[0024] For details, please refer to Figure 1 or Figure 3 A cover plate 13 is installed on the mold 9. The outer dimensions of the cover plate 13 are larger than those of the mold 9. The outer dimensions of the cover plate 13 match the internal dimensions of the open test block box 2.
[0025] For details, please refer to Figure 1 The pallet 3 is provided with a positioning frame 14; furthermore, the positioning frame 14 is located directly below the mold 9.
[0026] For details, please refer to Figure 3 A limiting frame 16 is provided in the lower middle part of the open test block box 2; furthermore, the limiting frame 16 is used to limit the downward movement of the tray 3.
[0027] In this embodiment of the concrete strength testing equipment, when testing the strength of concrete test blocks, the cover plate 13 seals the upper part of the open test block box 2 to prevent debris generated during the crushing of the concrete test blocks from flying out from the top of the open test block box 2; the positioning frame 14 can serve as a reference for placing the concrete test blocks on the support plate 3 to ensure the accuracy of the placement of the concrete test blocks; and the limiting frame 16 can limit the lower limit position of the support plate 3 in the open test block box 2 to prevent the support plate 3 from moving too far down and causing the spring 5 to be over-compressed, leaving sufficient margin for the compression of the spring 5 and preventing the spring 5 from being damaged.
[0028] Example 2
[0029] The concrete strength testing equipment provided in Example 1 has been further optimized. For details, please refer to [link / reference needed]. Figure 3 It also includes a hopper 10 installed on the open test block box 2. The hopper 10 includes a horizontal part and an inclined slope part. The inner bottom wall of the horizontal part is flush with the top of the open test block box 2.
[0030] For details, please refer to Figure 1 Alternatively, a pusher plate 11 is slidably installed at the horizontal part of the hopper 10, and a pusher assembly 12 is installed on the detection table 1 to provide power for the sliding of the pusher plate 11; furthermore, the width of the pusher plate 11 matches the width at the horizontal part of the hopper 10, and the pusher assembly 12 is preferably a telescopic cylinder, or the pusher assembly 12 can also be a linear motor or other equivalent components that drive the pusher plate 11 to slide.
[0031] Specifically, the open test block box 2, the cover plate 13, and the feeding hopper 10 are all made of transparent acrylic material.
[0032] For details, please refer to Figure 1 The pusher plate 11 is provided with two limiting bars 15 that correspond to the positioning frame 14; furthermore, the width between the two limiting bars 15 matches the width of the concrete test block to be tested.
[0033] The concrete strength testing equipment provided in this embodiment, after the mold 9 is reset, the support plate 3 is reset under the action of the spring 5. The top of the support plate 3 is flush with the inner bottom of the horizontal part of the hopper 10, so that the crushed concrete debris falls to the horizontal part of the hopper 10. The pushing component 12 is started, and the pushing plate 11 pushes the concrete debris at the horizontal part to the inclined slope. The operator can collect the concrete debris below the inclined slope. The operation is convenient, further reducing the amount of manual operation and improving the convenience of cleaning concrete debris. The limiting strip 15 can be used to limit the loading position of the concrete test block. The concrete test block is placed between the two limiting strips 15, and the pushing component 12 is started. The pushing component 12 pushes the concrete test block to the support plate 3, improving the loading position accuracy of the concrete test block at the support plate 3. At the same time, it avoids the manual loading of the concrete test block below the mold 9, reducing the mechanical injury accident rate and further improving the operational safety. The transparent acrylic material has good structural strength and makes it easy for the operator to observe the real-time status of the concrete test block in the open test block box 2.
[0034] The usage process of the concrete strength testing equipment provided by this utility model is as follows: The concrete specimen to be tested is placed at the horizontal position of the hopper 10, with the specimen positioned between the two limiting blocks 15. The pushing component 12 is activated, causing the pusher plate 11 to move. The concrete specimen moves into the positioning frame 14 at the support plate 3, and the pusher plate 11 resets. The pressure cylinder 7 is activated, extending its output end. The pressing mold 9 presses the concrete specimen into the open specimen box 2 until the specimen is completely inside the open specimen box 2, at which point the bottom of the support plate 3 contacts the top of the limiting block frame 16. Plate 3 can no longer move down to the bottom of the open test block box 2. As the output end of pressure cylinder 7 continues to extend, the mold 9 continues to move down until the concrete test block is crushed. The maximum pressure value is detected by pressure detector 8, and the compressive strength limit value of the concrete test block is obtained. The mold 9 is reset, and under the action of spring 5, the support plate 3 moves up until the top surface of the support plate 3 is flush with the bottom wall of the horizontal part of the hopper 10. The pushing component 12 is activated, and the pushing plate 11 pushes the concrete fragments in the hopper 10 from the horizontal part of the hopper 10 to the inclined slope of the hopper 10. The operator can then collect the concrete fragments.
