Drop impact testing machine for large dangerous cargo transporting package containers

Abstract

The invention relates to a drop impact testing machine for large dangerous cargo transporting package containers. The upper ends of two support upright posts are connected with a fixed cross beam to form an n-shaped frame, and the lower ends are respectively fixed with one fixing plate. Two screw rods are respectively arranged at the inner sides of the two support upright posts, and are parallel with the two support upright posts and fixed between the fixed cross beam and the fixing plate to freely rotate. The inside surfaces of the two support upright posts are respectively fixed with a guide rail, and two slide blocks are respectively fixed at both ends of a movable cross beam and arranged on the two guide rails. The two screw rods penetrate through the through holes at both ends of the movable cross beam. Two servo motors are respectively fixed on two speed reduction boxes, and the two speed reduction boxes are respectively fixed at the lower ends of the two sides of the movable cross beam, and sleeved on the two screw rods by threads. A release device is fixed at the center of the lower end surface of the movable cross beam. A testing and controlling device is arranged in a groove of the movable cross beam. The testing machine realizes automation of the hanging / dropping complete process of the packaging piece with the weight of 20 kilograms to 2 tons, has the advantages of convenient operation, good lifting stability, low mechanical noise and high accuracy, eliminates the safety hazard caused by manual operation, and can be widely applied to testing various large-weight cargo packages.

Description

technical field [0001] The invention relates to an impact drop test machine for a cargo transport packaging container, in particular to an impact drop test machine for a large dangerous goods transport packaging container. Background technique [0002] Dangerous goods have special and strict requirements on packaging, stowage, isolation, loading and unloading, management, transportation conditions and fire first aid measures. Among them, the drop test is the most commonly used important test method to verify the impact resistance of packaging in the circulation process. At present, there are special and stereotyped product equipment for the production and use of drop test equipment below 300 kg, and there are many in China. Testing machine manufacturers are in production. However, the drop test equipment for testing heavy dangerous goods packages weighing more than 300 kg is still blank in China, and no such drop test equipment products have been found abroad. In addition,...

Problems solved by technology

However, the drop test equipment for testing large-weight dangerous goods packages weighing more than 300 kg is still blank in China, and no such drop test equipment products have been found abroad.

In addition, the existing drop test for more than 300 kg only has a release device for hanging the test sample, without complete equipment, and there are unsafe factors in the use process
