Description

Technical Field

[0001] The invention relates to the technical field of lifting devices, in particular to a rotatable lifting device. Background Art

[0002] At present, with the continuous advancement of science and technology, the market demand for various commodities is also increasing. Manual production has begun to be replaced by assembly line production. In the process of assembly line production, automatic transmission devices are usually required. The produced goods are sent to various production workshops through the conveying device to complete the required steps.

[0003] A single conveying device can only complete the transfer of intermediate products in a straight line. In order to improve the reprocessing efficiency of intermediate products, it is often necessary to disperse the intermediate products to multiple processing stations so that multiple stations can simultaneously reprocess the intermediate products. Traditionally, the common practice is to set a diversion device at the unloading end of the conveying device, and each conveying outlet of the diversion device is separately connected to a conveying device to complete the process of transporting the intermediate products to each processing station. However, this type of transfer method requires a large amount of factory area. For this reason, the three-dimensionalization of the conveying system has become an important measure to save factory space. In a three-dimensional conveying system, a lifting device is required to transfer products between conveying devices at different levels. However, traditional lifting devices only have the function of vertical lifting. Therefore, in order to meet processing needs, multiple lifting devices are often set up to transfer the intermediate products on the main conveying device to another level of conveying devices in different directions.
