Description

[0002] Concrete is an important component of building structure, and its strength is directly related to the stability and safety of the building. By testing the strength of concrete, the problem of insufficient strength can be discovered in time, and corresponding measures can be taken to reinforce or rectify it, so as to prevent safety accidents caused by substandard concrete strength. The existing technology uses a probe to test the strength of concrete by a probe method. It mainly uses a transmitter to launch nails with scales to make the nails enter the concrete wall. The depth of the nails penetrated into the concrete wall is observed through the scales on the nails, and then the strength of the concrete is judged. The same side of the concrete wall is shot multiple times, and the average value is taken for final determination. However, after the nails are shot into the wall, they need to be manually pulled out using other tools. The operation intensity is large, and the time for the next shooting operation is wasted, which affects the detection efficiency. In addition, not only the detection device itself is required, but also additional nail pulling equipment needs to be carried, which is inconvenient to carry. Summary of the invention

[0030] Please refer to when using Figure 4-7, hold the power socket 24, press the button 25, the electric push rod 17 starts, the electric push rod 17 drives the second sleeve 18 to move toward the first sleeve 12, the connecting rod 22 and the triangular pyramid 23 also move, when the triangular pyramid 23 contacts the round end of the second lever 16, the second lever 16 is squeezed by the inclined surface of the triangular pyramid 23 and moves toward the inside of the first sleeve 12, the second lever 16 drives the first movable plate 14 to move toward the limit plate 13, the second spring 15 is compressed between the first movable plate 14 and the limit plate 13, when the triangular pyramid 23 reaches one side of the second lever 16, at this time, the signal transmitter 4 and the signal The signal receiver 6 is in the same horizontal plane relative to each other, the signal transmitter 4 transmits a signal to the signal receiver 6, and the signal receiver 6 feeds back the signal to the electric push rod 17, so that the electric push rod 17 drives the second sleeve 18 to move back. At this time, the second lever 16 breaks free from the restriction of the triangular pyramid 23 and rebounds, just against the triangular pyramid 23 and the connecting rod 22. When the triangular pyramid 23 moves back, the triangular pyramid 23 pulls the second lever 16 to move back as well, the second lever 16 drives the first sleeve 12, the second sleeve 18 drives the probe 3, the probe 3 drives the circular sliding plate 10 to move, and the circular sliding plate 10 drives the first spring 9 The probe 3 is stretched on the circular fixed plate 8, and moves on the conical limiting body 2.

The third lever 21 is squeezed by the first lever 7 and moves toward the second sleeve 18. The third lever 21 drives the second movable plate 19 to move. The second movable plate 19 drives the third spring 20 to stretch. The third lever 21 drives the connecting rod 22 and the triangular pyramid 23 to move, so that the connecting rod 22 and the triangular pyramid 23 deviate to one side of the second lever 16. The second lever 16 loses the restriction of the triangular pyramid 23. Under the action of the spring 9, it rebounds quickly, the first spring 9 drives the circular sliding plate 10, and the circular sliding plate 10 drives the probe 3 to be rapidly launched, so that the probe 3 is shot into the concrete wall. By checking the scale on the probe 3, the depth of the probe 3 inserted into the concrete wall is known, and the strength of the concrete is then detected. It is worth pointing out that since the depth of the probe 3 shot into the concrete wall is different, the signal transmitter 4 and the signal receiver 6 are set to enable the triangular pyramid 23 to accurately capture the specified position of the probe 3, ensuring that the triangular pyramid 23 can reach one side of the second lever 16 to pull the second lever 16 back.
