Abstract

The invention is suitable for the technical field of automatic locks of containers, and provides a testing method capable of simultaneously testing the strength of a plurality of automatic container locks. The testing method comprises the following steps of: installation of a tested automatic container lock: installing the tested automatic container lock on a testing machine, enabling the tested automatic container lock to be at a first preset angle, and enabling the tested container automatic lock to be at a second preset angle, wherein the specification of the selected testing machine is 50-8000 kN; and compression test of the tested automatic container lock: conducting loading with the test force of the testing machine of 50 kN as a start point, wherein a loading speed is 20-60 kN / s, keeping the test load for 10-50 min after a test load is reached, and then conducting unloading. According to the invention, the automatic container lock to be tested is tested and observed, loading iscarried out step by step according to an observation result, and operation is repeated until a pressure range capable of damaging the automatic container lock to be tested is determined; and the method has the advantages of being easiness, convenience in implementation, visualness, high operability, reliable and accurate data, high testing efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of container automatic locks, in particular to a testing method capable of simultaneously testing the strength of multiple container automatic locks. Background technique [0002] Container lock (container automatic lock), container transportation is the safest carrier of modern cargo transportation, and safety is the "lifeline" of container transportation. Once the box body carrying more than ten tons of cargo slips or rolls over and leaves the car body, it will cause immeasurable losses to personal life and property safety. Therefore, the container and the car body must be connected and fixed by special locks. According to the relevant provisions of the Ministry of Communications of the People's Republic of China in the “Regulations on Road Freight Transport and Station Management” (No. Equipped with a twist lock device for securing the container. [0003] The purpose of the container lock is to ensur...
