A crane with three-angle anti-tilt device

Abstract

A crane with anti-tilt devices at three angles, including trolley, rails, anti-tilt devices, load-bearing cables and adjusting cables. The trolley is located on the track, and the four corners of the trolley are connected to the four corners of the rectangle of the anti-tilt device through 4 load-bearing cables, and the four corners of the rectangle of the anti-tilt device are correspondingly connected to the four corners of the container through short cables. A detection adjustment plate is arranged in the middle of the anti-tilt device, which is used to detect the tilt deflection of the container in three directions, and is also used to adjust the tilted container. The scheme is simple in structure and has a good effect of preventing the container from tilting.

Description

technical field [0001] The invention relates to the field of cranes, in particular to the field of anti-tilting cranes. Background technique [0002] When loading and unloading container cargo in a windy environment, since the container is hoisted by ropes, it will be affected by the strong wind, causing the container to rotate in the horizontal plane (XY plane) or tilt in the vertical plane (XZ plane or YZ plane). When the container rotates on the XY plane, the container cannot be aligned with the container already in place, thus affecting the stacking of the container; when the container is tilted on the XZ plane (YZ plane), it will cause one side of the container to touch the ground first (or other containers), resulting in damage caused by uneven force. Therefore, angular rotation in all three directions can lead to undesired behavior. [0003] At present, there are only some solutions to prevent tilting at one or two angles, and there is no solution that can prevent a...

Problems solved by technology

However, the use of optical methods requires more sophisticated instruments and high costs; multiple angle encoders need to be installed; machine vision methods have higher requirements for ambient light

[0004] Moreover, after the angle rotation or inclination is found, it is usually adjusted by tightening the rope, but this method cannot solve the problem of the horizontal rotation of the container

In order to solve this problem, a rigidly connected rotating device is usually required, which in turn increases the weight of the moving parts of the crane, which poses a greater safety hazard

In addition, in the prior art, various adjustments are usually placed in the trolley, which makes the structure of the trolley on the track extremely complicated, which makes the trolley the most fragile part of the crane and cannot be used in harsh environments

[0005] In addition, usually the detection device and the adjustment device are two separate devices, which undoubtedly increases the complexity of the crane and reduces its reliability in harsh environments
