[0026] The first positioning plate 7 is provided with an infrared emitter 11 at the middle of the front end, and the second positioning plate 8 opposite to the first positioning plate 7 is provided with an infrared receiver 12 at the middle of the front end, and the infrared emitter 11 and the infrared receiver 12 are electrically connected with the single-chip microcomputer.

[0027] The front end of the first positioning plate 7 and the front end of the second positioning plate 8 are provided with a touch switch 13, and the touch switch 13 is electrically connected with the single-chip microcomputer.

[0028] Exemplarily, in use, the concrete test piece is first placed on the part of the conveying module 16 outside the protective shell 1, and then the conveying module 16 transmits the concrete test piece into the protective shell 1 for detection, avoiding the danger of working in the device. When the concrete test piece is conveyed to the front of the first positioning plate 7 of the first electric rod, the infrared signal emitted by the infrared emitter 11 at the front end of the first positioning plate 7 is blocked by the concrete test piece, and the infrared receiver 12 on the second positioning plate 8 at the other end cannot receive the infrared signal. At this time, the single-chip microcomputer controls the first electric push rod 5 and the second electric push rod 6 to work, the first positioning plate 7 on the first electric push rod 5 pushes the concrete test piece to move to the direction of the pressure receiving position, and the second electric push rod 6 drives the second positioning plate 8 to move to the direction of the concrete test piece.

When the concrete test piece is broken, the pressure on the pressure sensor drops suddenly, and when the single-chip microcomputer detects that the data sent by the pressure sensor suddenly changes, the detection is completed at this time, and the single-chip microcomputer controls the hydraulic pump 2 to return to the original position and performs corresponding data processing.

[0034] The protective shell 1 is provided with an LED lamp 14 on the outer side, and the LED lamp 14 is electrically connected with the single-chip microcomputer.

[0035] Exemplarily, when the concrete test piece completes the detection and the cleaning, the LED lamp 14 flashes, and at this time, the worker can perform the detection of the next test piece. When the single-chip microcomputer controls the positioning module to work, the LED lamp 14 is turned off.

[0036] The protective shell 1 is provided with a support column 15 inside.
