Abstract

The invention discloses a detecting and testing device for a falling object protection structure, belonging to the technical field of testing equipment for drop hammers. The detecting and testing device comprises a mechanical system, a measuring system and a control system. The mechanical system comprises a foundation platform for the device and a guide rail platform, wherein the guide rail platform comprises an X-direction guide rail and a Y-direction guide rail; the X-direction guide rail is mounted on the Y-direction guide rail through a Y-direction sliding member; the Y-direction guide rail is mounted on the foundation platform for the device through stand columns; a drop hammer lifting and releasing protection unit is mounted on a moving beam unit and comprises a bottom support connected to the X-direction guide rail by an X-direction sliding member; and a drop hammer mechanism for driving a drop hammer to move along a Z direction is mounted on the bottom support. The measuring system comprises a distance measuring sensor for detecting the Z-direction height of the drop hammer, a deformation and displacement sensor for detecting the deformation quantity of the drop hammer, a data acquisition card, and a controller. The control system comprises a power control cabinet, a programmable controller, a servo driver, an interface board and an industrial computer. The detecting and testing device of invention can realize the detection of falling objects at different heights.

Description

technical field [0001] The invention belongs to the technical field of drop weight testing equipment, and in particular relates to a testing device for detecting and testing a falling object protective structure. Background technique [0002] In the original falling object protection structure detection and testing equipment, the drop point position of the drop hammer and the lifting height of the drop hammer are relatively fixed. Basically, the test piece can only be adjusted to the tested state through the fixed tooling; the drop hammer is manually installed and released; The test results measure the final deformation with a ruler or the like. The above-mentioned operations are time-consuming and labor-intensive, and the safety guarantee is not strong. At the same time, the measurement accuracy is limited, and it is not yet possible to measure the instantaneous maximum deformation. Contents of the invention [0003] Aiming at the defects of the prior art, the present in...
