In this embodiment, the penetrating clamp 4 and the pulling clamp 5 both include a pretightening nut 8, a first spring 9, a slip 10, a locating sleeve 11, a top sleeve 12 and an ejecting nut 13, both ends of the locating sleeve 11 are respectively provided with an internal thread and an external thread, the pretightening nut 8 and the locating sleeve 11 are provided with an internal threaded one end threaded connection, the ejecting nut 13 and the locating sleeve 11 are provided with an external threaded one end threaded connection, the slip 10 is arranged in the locating sleeve 11 at the middle part and is in sliding connection with the locating sleeve 11 through conical surface fit, the first spring 9 is arranged in the locating sleeve 11, both ends of the first spring 9 are respectively abutted against the big ends of the pretightening nut 8 and the slip 10, and the top sleeve 12 is also arranged in the locating sleeve 11 and is positioned between the slip 10 and the ejecting nut 13. In this embodiment, the slip 10 is composed of two sets of slip units disposed oppositely, and a movable gap is provided between the two sets of slip units.

In this embodiment, the constant-force fixture 6 includes a base 14, a first roller 15, a second roller 16, a first roller support 17, a tightening screw 18, a second spring 19, and a sliding seat 20, where the first roller 15 and the second roller 16 are symmetrically installed in the base 14 through a set of first roller supports 17, the first roller support 17 for installing the first roller 15 is directly and fixedly connected to the base 14, the second roller support 17 for installing the second roller 16 is slidably connected to one side of the sliding seat 20, the tightening screw 18 is in threaded connection with the other side of the sliding seat 20, the second spring 19 is installed in the sliding seat 20, two ends of the second spring 19 abut against wheel surfaces of the tightening screw 18 and the second roller 16, and the sliding seat 20 is fixedly connected to the base 14.

In this embodiment, the large end of the slip 10 is provided with an annular positioning groove 21, and one end of the first spring 9 is arranged in the annular positioning groove 21.

In the embodiment, the roller support 17 for mounting the second roller 16 and the tightening screw 18 are oppositely provided with a cylindrical mounting groove 22, and the second spring 19 is arranged in the cylindrical limiting groove 22.

The static sounding device clamp is matched with a probe rod clamp of a static sounding device for use, and when the oil cylinder 1 penetrates into and pulls out a probe rod, the probe rod clamp loosens the probe rod; when the oil cylinder 1 is intermittently reset in the process of penetrating and pulling out the probe rod, the probe rod clamp clamps the probe rod, and the constant-force clamp 6 is matched with the probe rod clamp in the process, so that the probe rod is prevented from falling due to dead weight.

The probe rod sequentially passes through the penetration fixture 4, the pulling fixture 5 and the constant force fixture 6, when the probe rod penetrates, an ejection nut 13 of the pulling fixture 5 needs to be rotated upwards, a jacking sleeve 12 jacks up a slip 10 upwards, the slip 10 of the pulling fixture 5 is not in contact with the probe rod at the moment, the oil cylinder 1 initially extends to the longest state, the oil cylinder 1 contracts, the penetration fixture 4 clamps the probe rod, the pulling fixture 5 is loosened, the penetration fixture 4 drives the probe rod to move downwards, the oil cylinder 1 contracts to the shortest position and then resets, and the actions are repeated to realize penetration of the probe rod; when the feeler lever is pulled out, the slips 10 in the pulling fixture 5 are reset to be in contact with the feeler lever, then the ejection nut 13 of the injection fixture 4 is rotated downwards, the slips 10 are pushed downwards by the ejector sleeve 12, the slips 10 injected into the fixture 4 are not in contact with the feeler lever at the moment, the oil cylinder 1 initially contracts to the shortest state, the oil cylinder 1 extends, the pulling fixture 5 clamps the feeler lever, the injection fixture 4 is loosened, the pulling fixture 5 drives the feeler lever to move upwards, the oil cylinder 1 resets after extending to the longest state, the actions are repeated, and pulling of the feeler lever is realized. In addition, the probe rod is always clamped by the constant-force clamp 6, and the friction force between the constant-force clamp 6 and the probe rod is slightly larger than the dead weight of the probe rod, so that the probe rod is prevented from falling due to the dead weight.

When the probe rod moves downward, the principle of operation of the penetration jig 4 is as follows: the slip 10 is driven to move upwards by the friction force between the probe rod and the slip 10, the clamping surface of the slip 10 to the probe rod is reduced, and larger clamping force can be applied to the probe rod; when the probe rod moves upwards, the slips 10 of the pulling fixture 5 move downwards to clamp the probe rod. When the probe rod needs to be taken out, the ejection nut 13 of the clamp 5 is upwards screwed up or the ejection nut 13 penetrating into the clamp 4 is downwards screwed, so that the slip is jacked up by the jacking sleeve 12, and the clamp can lose the effect. In order to avoid the influence of soil on the clamp, soil blocking rings can be arranged at the two ends of the clamp.

When the constant-force clamp works, the first roller 15 and the second roller 16 of the constant-force clamp 6 always clamp the probe rod, but the clamping force is only larger than the dead weight of the probe rod and far smaller than the penetrating force and the pulling force of the oil cylinder 1, and the friction force between the first roller 15 and the second roller 16 and the probe rod is adjusted by rotating and screwing the nut 18.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
