Container Weighing Device

Abstract

The invention relates to a container weighing device, which includes an I-shaped hanger, a support, a load cell and a wireless transmitting module. The four corners of the hanger are respectively equipped with supports, and each support has a Support arm, the upper part of each load cell is connected with the support arm through the upper pin shaft and joint bearing, the lower part of each load cell is connected with the floating seat through the lower pin shaft and joint bearing, and the rotating shaft fixed with the boom is connected with the floating seat through the plane bearing To connect, four wireless transmitting modules are respectively installed on the hanger, and the signal output lines of each weighing sensor are connected to the signal input ends of the respective wireless transmitting modules. In the process of hoisting the container, the invention can quickly and accurately weigh the four corners of the container to judge whether the container is eccentric, and can improve the safety and efficiency of hoisting.

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...

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
