Telescopic rock-soil body bearing capacity testing device

Abstract

The utility model relates to the technical field of rock-soil body bearing capacity testing, in particular to a telescopic rock-soil body bearing capacity testing device. The utility model provides a telescopic rock-soil body bearing capacity testing device which can automatically clamp, lift and loosen a knocking block and guide the knocking block at the same time, ensures that the hammer drop points of the knocking block are always at the same position, and ensures the testing accuracy. A telescopic rock-soil body bearing capacity testing device comprises a base, folding frames and the like, and the folding frames are rotationally arranged on the front portion and the rear portion of the base. According to the utility model, the clamping block moves downwards to contact with the right part of the knocking block, the clamping block clamps the knocking block, and after the connecting block moves upwards to a certain position, the extrusion block extrudes the clamping block and drives the clamping block to move outwards, so that the knocking block hammers the test rod, and the purposes of automatically clamping, lifting and loosening the knocking block and simultaneously guiding the knocking block are achieved; and the hammering point of the knocking block is always at the same position, so that the test accuracy is ensured.
