Abstract

The present invention discloses a fall-back stop mechanism for a super-large dropping device. The super-large dropping device comprises a track having a U-shaped bottom and a product test vehicle installed on the track; the fall-back stop mechanism comprises a plurality of double wedges disposed at the final segment of the track and arranged at intervals along the up-down direction and a test vehicle stop motion device installed on the product test vehicle, a lower block is arranged at the position below the double wedge located at the lowest end on the final segment of the track, and an upper block is arranged at the position over the double wedge located at the uppermost end on the final segment of the track; and the test vehicle stop motion device comprises a fitting seat, a fall-back stop block, a rotating shaft, an unlocking hook plate, a locking sliding plate, a reset pull plate, a tension spring and a rotating shaft torsion spring. Through adoption of a set of a combination mechanism provided by the invention, the automatic flows of unidirectional movement, fall-back stop, unlocking and resetting of the product test vehicle may be realized. Moreover, the fall-back stop mechanism for a super-large dropping device has simple structure, is easily realized and is safe and reliable.

Description

technical field [0001] The invention relates to an auxiliary mechanism for a drop device, in particular to a fall-back stop mechanism for a super-large drop device. Background technique [0002] The drop test device is an important scientific test device that uses the earth's gravity field to simulate mechanical impacts such as drops and impacts on products during transportation and use. It is an important indicator of reliability design to test the product's anti-drop ability through this device, and it provides an important research method for reasonable product packaging design. [0003] The drop test device generally consists of a lifting mechanism, a releasing mechanism, an attitude maintaining mechanism, a buffer mechanism, and control and testing equipment. During the operation of the drop test device, a large kinetic energy will be generated. Wherein, the buffer mechanism is used for buffering and absorbing the remaining kinetic energy of the attitude maintaining m...
