[0019] The mobile lifting mechanism includes a groove slide rail 10, a sliding seat 11, a synchronous screw 12, a driving motor 13, a multi-section lifting rod 14 and a multi-section sleeve 15. The groove slide rails 10 are symmetrically arranged on both sides of the mobile base plate 1. The middle part of the groove slide rail is a groove-shaped structure. The sliding seat 11 is slidably arranged on the groove slide rail 10. The synchronous screw 12 is arranged in the groove slide rail 10.

[0020] The bottom of the sliding seat 11 is threadably matched with the synchronous screw 12, and the output end of the driving motor 13 is driven by one end of the synchronous screw 12. The synchronous rotation of the synchronous screw drives the sliding adjustment of the sliding seat on the groove slide rails on both sides.

[0022] The through hole mechanism includes a through hole 20, a water spray port 21 and a water tank 22. A through hole 20 is arranged directly below the core drilling tube 5. Water spray ports 21 are distributed on the inner wall of the through hole 20. A water tank 22 is arranged on one side of the through hole on the movable bottom plate 1.

[0023] The upper end of the core drilling barrel 5 is threadedly installed with the lower end of the rotating barrel 4 and locked by a fixing pin 23. When core drilling sampling at different depths is performed, core drilling barrels of different lengths can be replaced, which is convenient and quick.

[0025] When the concrete sampling device for civil engineering testing is used, the device is first moved to the location where sampling testing is required, and then the device is reset. At this time, the sliding seat corresponds to the position of the through hole, and the sliding plate above the lifting plate is located in the middle of the lifting plate, so that the rotating cylinder and the core drilling cylinder below are concentric with the through hole. Then the core drilling motor drives the rotating cylinder and the core drilling cylinder below to rotate, and the multi-section lifting rod retracts, driving the lifting plate to move downward, so that the core drilling cylinder contacts the concrete floor, and slowly moves downward to perform core drilling;

[0026] After the core drilling is completed, the core drilling barrel stops rotating, the telescopic rod drives the sampling ferrule to move downward, and the inner inclined surface below the sampling ferrule is inserted into the gap between the sample core and the inner wall of the core drilling barrel to tightly clamp the sample core in the core drilling barrel. Then the multi-section lifting rod is controlled to rise, and the sample core is lifted and taken out of the borehole. Subsequently, the synchronous screw rotates to drive the sliding seat to move, and the moving plate mechanism is adjusted to move the core drilling barrel to the top of the storage barrel. Then the multi-section lifting rod retracts to drive the lifting plate to move downward to insert the core drilling barrel into the storage barrel. The telescopic rod retracts to retract the sampling ferrule, and the sample core falls into the storage barrel. Finally, the device is reset to carry out drilling sampling at the next location.
