Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Referring to fig. 1-2, a foundation pile dynamic test apparatus includes: pile foundation detector main part 1, detection head 2, strike hammer 3.

Detect first 2 through connecting wire and 1 electric connection of pile foundation detector main part to strike the pile foundation through beating hammer 3, then detect first 2 and gather the signal on the pile foundation, and realize pile foundation detector main part 1 through the connecting wire and carry out the analysis and record.

The knocking hammer 3 comprises a hammer handle 31, a pressure adjusting piece and a hammer head 32, wherein the hammer handle 31 is connected with the hammer head 32 through the pressure adjusting piece.

The pressure adjusting part comprises a fixing rod 33, a sliding cylinder 34 and an adjusting part, the fixing rod 33 is fixedly connected with the hammer handle 31, the fixing rod 33 is slidably connected with the inside of the sliding cylinder 34, one end, far away from the hammer handle 31, of the sliding cylinder 34 is fixedly connected with the hammer head 32, and the adjusting part is arranged between the fixing rod 33 and the sliding cylinder 34.

The adjusting piece comprises a fixing block 35, an extrusion plate 36, a connecting spring 37 and a pressurizing screw 38, the fixing block 35 is fixedly connected with the sliding cylinder 34, the fixing block 35 is arranged by penetrating through the fixing rod 33, the extrusion plate 36 is slidably connected inside the fixing block 35 and is abutted against the fixing rod 33, the connecting spring 37 is fixedly connected with the extrusion plate 36, the pressurizing screw 38 is in threaded connection with the fixing block 35, and the pressurizing screw 38 is abutted against the connecting spring 37.

Thereby can ensure through the extrusion force of difference between extrusion plate 36 and the dead lever 33 that there is the static friction power of equidimension not between extrusion plate 36 and the dead lever 33, at the in-process of knocking, when the dynamics of hand was suitable, the relative effort between the in-process extrusion plate 36 of knocking and the dead lever 33 is less than the static friction power between extrusion plate 36 and the dead lever 33, and then realize the relative fixation between extrusion plate 36 and the dead lever 33 this moment, with realize can hand hammer handle 31 realize that tup 32 knocks to the pile foundation. And if when the dynamics of hand is great, the relative effort between 36 and the dead lever 33 of the in-process stripper plate of knocking is greater than the static friction between 36 and the dead lever 33, and then realize after tup 32 and pile foundation surface contact, relative slip between 36 and the dead lever 33 of stripper plate, also be the relative slip between dead lever 33 and the slip tube 34, and then when avoiding handheld hammer handle 31, the tup is too big to the dynamics of pile foundation knocking the circumstances takes place.
