Abstract
The invention relates to a drop test device and method, in particular to a packaging box drop test device and method. The packaging box drop test device and method are used for solving the problems that due to the fact that a gunpowder cutting cable is used for cutting a lifting rope in an existing packaging box drop test, potential safety hazard exist, and manpower and material resources are consumed. The lower end face of a magnetic crane makes contact with the upper end face of a connecting base through magnetic force, a lifting hook is fixedly installed on the lower end face of the connecting base, and the connecting base is connected to a main lifting hook through a protective rope. The packaging box drop test method comprises the steps that (1) the magnetic crane attracts the connecting base through the magnetic force, and a lifting rope is installed on four lifting points on the upper end face of a packaging box containing military products; (2) the protective rope on the connecting base is hung on the main lifting hook of the magnetic crane; (3) the magnetic crane ascends, the packaging box containing the military products ascends at the same time, and it is ensured that the vertical distance between the bottom end face of the packaging box containing the military products and the ground ranges from 0.45 m to 1 m; (4) the connecting base is separated from the magnetic crane, and the packaging box containing the military products can fall on the ground. The packaging box drop test device and method are used for a packaging box drop test.

Packing case fall-down test method of the present invention realizes according to following steps:
Method one:
Step 1, open magnetic switch, by magnetic crane by magnetic force by Connection Block adhesive, lifting rope is arranged on four suspension centres of the packing case upper surface that military products are housed, four suspension centres are the uniform setting of matrix;
Step 2, the protective rope on Connection Block is hung on the main hoisting hook of magnetic crane;
Step 3, then magnetic crane is upwards risen, the packing case that military products are housed simultaneously also rises simultaneously,
The bottom face that the packing case of military products is equipped with in assurance is 0.45～1m to the vertical distance on ground;
Step 4, finally close magnetic switch, Connection Block and magnetic crane are departed from, the packing case that military products are housed falls on the ground.
Method two:
Step 1, open magnetic switch, by magnetic crane by magnetic force by Connection Block adhesive, lifting rope is arranged on two suspension centres of packing case one side that military products are housed, two suspension centres are symmetrical arranged;
Step 2, the protective rope on Connection Block is hung on the main hoisting hook of magnetic crane;
Step 3, then magnetic crane is upwards risen, the packing case that military products are housed simultaneously also rises simultaneously, it is 0.45～1m to the vertical distance on ground that a side bottom face described in the packing case of military products is equipped with in assurance, cushion block on pad is being housed between the lower surface of opposite side of packing case of military products and ground, the height that guarantees cushion block with the packing case of military products is housed described in a side bottom face to the vertical distance on ground, equate;
Step 4, finally close magnetic switch, Connection Block and magnetic crane are departed from, the side being equipped with described in the packing case of military products falls on the ground.
The invention has the beneficial effects as follows:
Packing case fall-down test device of the present invention adopts magnetic crane to carry out packing case fall-down test, has saved the use of priming system, has stopped potential safety hazard, to not restriction of test site, has greatly saved manpower and materials; And Connection Block is connected with protective rope, when magnetic crane loses magnetic force, Connection Block, suspension hook and the packing case that military products are housed fall simultaneously, and Connection Block and suspension hook can not continue to fall under the constraint of protection rope, thereby protected the case lid of packing case not to be destroyed, guaranteed the feasibility of test; Packing case fall-down test device of the present invention only need once be invested, and can repeatedly carry out hundreds of time test;
Packing case fall-down test device method of the present invention has realized packing casing integral body to be fallen the angle of mode and various angles and falls mode and test, and method of the present invention adopts magnetic force of permanent magnet to hang, and is not therefore subject to the restriction of weather and power supply.
