This application provides a drop testing device and method for hollow blocks. The drop testing device for hollow blocks includes a clamping mechanism, a posture adjustment mechanism, a release mechanism, and an impact surface mechanism. The clamping mechanism includes at least two pairs of clamps, one of which is higher than the other. At least one of the at least two pairs of clamps operates to clamp hollow blocks in corresponding postures. The upper clamp in a pair is connected to the posture adjustment mechanism, which drives the upper clamp to move to a clamping position corresponding to the posture of the clamped hollow block. The lower clamp in a pair is connected to the release mechanism, which drives the lower clamp to release the clamp from the hollow block, allowing the hollow block to fall freely in its clamped posture. The impact surface mechanism is located below the clamping mechanism. This application provides strong traceability and an extremely short feedback cycle for the anti-breakage performance of hollow blocks.
