Verifying device and adjusting method of lifting appliance type container overload and unbalanced load detecting and weighing system

Abstract

The invention relates to a verifying device of a lifting appliance type container overload and unbalanced load detecting and weighing system. The verifying device comprises a trolley. A power supply system, a data display and a lifter are mounted on the trolley; the lifter is provided with a verification unit. The verification unit comprises a hydraulic jack, the upper portion of the hydraulic jack acts on the bottom plate of a spin lock box through a verification sensor and a force transmission support, and the counter-acting force of the hydraulic jack acts on the overload and unbalanced load weighing sensor through a left lining plate, a right lining plate, a lock pin buckle plate, a lock pin and a circular main shaft. The problem that the traditional standard weight can only verify thetotal weight of the container and cannot verify the unbalance loading of the container is solved.

Description

technical field [0001] The invention relates to a weighing verification device and method, in particular to a verification device and an adjustment method of a spreader-type container over-eccentric load detection and weighing system. Background technique [0002] Excess load detection and weighing for containers is a new type of measurement safety testing equipment that has only appeared in recent years. Existing manufacturers and inspection agencies still use traditional weight inspection and debugging methods, and the actual situation cannot meet the requirements of their products. The technical requirements of the container eccentricity data as an example, X=A / 2-(Fc+Fa)A / G; Y=B / 2-(Fc+Fd)B / G, such as Figure 7 As shown, it can be seen from the figure that the load of the container should be evenly distributed in the box, otherwise the measured Fa, Fb, Fc, and Fd are not equal, and calibration and debugging cannot be carried out (it is certain that the weight of dozens of t...

[0002] Excess load detection and weighing for containers is a new type of measurement safety testing equipment that has only appeared in recent years. Existing manufacturers and inspection agencies still use traditional weight inspection and debugging methods, and the actual situation cannot meet the requirements of their products. The technical requirements of the container eccentricity data as an example, X=A / 2-(Fc+Fa)A / G; Y=B / 2-(Fc+Fd)B / G, such as Figure 7 As shown, it can be seen from the figure that the load of the container should be evenly distributed in the box, otherwise the measured Fa, Fb, Fc, and Fd are not equal, and calibration and debugging cannot be carried out (it is certain that the weight of dozens of tons in the box cannot achieve uniformity. Placement requirements) Therefore, the factory inspection and debugging of the product are rough estimates, and the verification agency can only measure the weight, and the eccentric and eccentric load tests are all marked in the factory manual.
