Container weighing apparatus

Abstract

The invention relates to a container weighing apparatus which comprises an I-shaped hanger, supports, weighing sensors and wireless transmission modules, wherein the supports are respectively mounted on four corners of the hanger, each support is provided with a supporting arm connected with a base into a whole, the upper part of each weighing sensor is connected with the supporting arm through an upper pin shaft and a joint bearing, the lower part of each weighing sensor is connected with a floating seat through a lower pin shaft and the joint bearing, a rotating shaft fixed with a suspender is connected with the floating seat through a plane bearing, four wireless transmission modules are respectively mounted on the hanger and a signal output line of each weighing sensor is connected with the signal input end of the respective wireless transmission module. In the process of lifting the container, the invention can fast and accurately weigh the four corners of the container to judge whether the container is eccentric or not and can improve the lifting safety and efficiency.

Description

technical field [0001] The invention relates to a container weighing device, which belongs to the technical field of container main weight. Background technique [0002] During the transportation of the container, when the position of the center of gravity of the container deviates, it will cause safety hazards due to the tilt of the container, so the container will be weighed before transportation. At present, for the measurement of containers, special-purpose floor scales are usually installed on the ground. The four corners of the floor scale are provided with weighing modules, and the weight of the four corners of the container is weighed by the weighing modules to determine whether it is eccentric. However, in the process of container weighing, the container needs to be hoisted back and forth between the fixed weighing place and the transportation place by a special reach crane, not only the container needs to be hoisted up and down, but also the container needs to be a...

AI Technical Summary

Problems solved by technology

However, in the process of container weighing, the container needs to be hoisted back and forth between the fixed weighing place and the transportation place by a special reach crane, not only the container needs to be hoisted up and down, but also the container needs to be adjusted to the best position before weighing. Weight calculation is not only time-consuming and labor-intensive, especially the reach crane for hoisting containers consumes a lot of fuel, and the round-trip transportation wastes energy, which greatly reduces the hoisting efficiency and is not conducive to the rapid hoisting of the freight yard

The other is to use the four-corner hanging method to weigh the container. The load cell is installed at the end of the wire rope. This kind of weighing of the container can only be used on the door crane. Heavy, which also affects the hoisting efficiency

In addition, in the weighing device of this structure, the upper part of the load cell is connected to the sling ring through the upper hinge, and the lower part is connected to the suspender through the lower hinge. Since the load cell is subjected to oblique tension, this not only reduces the weighing accuracy, but also Also vulnerable to damage to the load cells
