And the replaceable firing pin 255 can also be used as a wearing part to protect the hammer pad 25, and the replaceable firing pin 255 is pressed by the guide sleeve 254, so that the replaceable firing pin 255 is more convenient to replace than the hammer pad 25, and is easy to repair and prolongs the service life of the hammer pad 25.
In this embodiment, compared with the conventional manually operated power feeler device, the hammering device 2 and the power feeler device lift the core through hammer 24 by a lifting mechanism instead of manpower, thereby reducing the labor intensity; in the hammering process, the height of the release through hammer 24 is judged by the height sensor 231, so that the testing precision is improved compared with manual judgment; and the release height of the perforating hammer 24 can be changed by changing the height of the height sensor 231;
because the guide rod 22 can slide up and down along the first guide hole, the hammer pad 25 can slide up and down along the second guide hole, the top surface of the limiting part 253 is contacted with the bottom surface of the lower frame 212 but is not fixedly connected with the lower frame, and the through hammer 24 falls on the top end of the hammer pad 25 in the hammering process, so that the damage to the mounting frame 21 can be reduced, and the service life is prolonged.
Because the construction site environment is complex, the situation that the ground is inclined is likely to occur, in this embodiment, the angle between the slide rail 121 and the base 11 can be adjusted by making the second piston rod 132 of the diagonal bracing cylinder 13 telescopic, so that the hammering direction of the hammering device 2 can be adjusted, and the offset of the hammering direction relative to the vertical direction can be reduced, so that the testing precision can be improved.
Since the hammering times are frequent during the sounding operation, the hammering device 2 itself may generate a certain vibration, so that the probe rod 3 may be deflected, and other conditions may cause the probe rod 3 to deflect. Thus, by providing the probe rod supporting seat 1231 on the supporting rail 12 for righting the probe rod 3, the probe rod 3 is kept vertical, so that the test accuracy can be improved. In addition, the probe rod supporting seat 1231 is openable and closable, and when the conical head is mounted at the bottom end of the probe rod 3, the radial dimension of the conical head is larger than the radial dimension of the rod body of the probe rod, so that the probe rod supporting seat 1231 can be opened before the probe rod is mounted, and then closed after being lifted to a proper height, thereby supporting the probe rod.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
