Description

Technical Field

[0001] The present invention relates to the field of hoisting, and in particular to a hoisting device for reducing the swaying of goods. Background Art

[0002] With the development of industrial technology, the field of modern lifting has become more and more perfect. The loading and unloading of goods inside the factory requires the use of small lifting devices. The previous lifting devices would have a lot of shaking when lifting the goods. This shaking could easily cause the crane boom to be subjected to lateral tension. This swaying force could even cause the lifting device to overturn. The lifting device for lifting and unloading the blind plate of the loading and unloading arm proposed in patent No. 202120044780.5 belongs to the field of lifting technology, and includes a fixed base, the upper surface of the fixed base is fixedly connected to the support rod, the left wall and the right wall of the support rod are fixedly connected to the reinforcement frame, the top of the support rod is fixedly connected to the fixing block, the upper surface of the fixing block is installed with an electric telescopic device, the right wall of the fixing block is fixedly connected to the cross arm, the surface of the cross arm is installed with an installation box, a winding roller is installed inside the installation box, the left wall of the installation box is embedded and connected to the motor, and the surface of the winding roller is wound with a hanging wire. The utility model provides a lifting device for lifting and unloading the blind plate of the loading and unloading arm, which is convenient for adjusting the position of the lifting structure, convenient for quickly fixing and lifting the blind plate, and does not need to be manually carried to the bottom end of the lifting structure for fixing, which saves time and effort and improves work efficiency. This invention also has the following defects when in use. First, there is only one hanging wire on the boom of the device, which is prone to swinging when the cargo is off the ground. This swinging can easily cause the crane to tip over, and the lateral force of the swinging will also cause pressure on the mechanical gap of the crane, accelerating the wear of the crane and reducing the service life of the crane. Second, if the boom of the crane is extended too long, the crane will easily tip over towards the boom when the cargo is lifted. Summary of the Invention
