Background

The weighing device for detecting overload and unbalance loading of container is mainly set on the equipment for loading and unloading container or special container hanger, and is one weighing and metering device capable of detecting overload, unbalance and unbalance loading of freight container. Due to various reasons, the phenomena of overload, left-right unbalance loading and front-back unbalance of the container filled with goods often occur, so that great potential safety hazards exist in the transportation process of the container. Taking railways as an example, overload and unbalance loading always have long been problematic problems which disturb the running safety of railway freight cars, and particularly along with the continuous speed increase of railways in China, the requirements of railway freight on overload and unbalance loading are more strict and strict, and serious accidents can be caused by slight negligence. Therefore, the Ministry of railways specially provides a management method for detecting and weighing an overload and an unbalance load of a railway wagon, and requires that scientific and technological means are used for strictly checking overload and unbalance load, wherein two methods are specified in a plaintext: 1. the phenomenon of overload and unbalance loading needs to be strictly checked by scientific and technological means; 2. the center of gravity of the cargo loaded by the container is required to be allowed to deviate as follows (distance from the central axis), with a lateral deviation of 200mm, a longitudinal deviation of 600mm (20 foot box) and 1200mm (40 foot box). In addition, in order to ensure the safety of the transport vehicle when passing through the curved road, the railway freight loading and strengthening regulation also stipulates: the maximum allowable displacement of the center of gravity of the container cargo from the longitudinal center line of the vehicle (i.e., lateral displacement of the center of gravity) is 100 mm.

The common container overload and unbalanced load detecting and weighing device is in the types of a weighbridge, a rail weigher, a hook weigher and the like. Weighing weighbridge is a mature method for weighing in a fixed place, containers to be measured need to be transported to fixed positions, empty containers and heavy containers need to be measured once after one-time weighing is completed, and when a plurality of containers are required to be detected, the workload is large.
