Chain-type lifting mechanism for carried cargo

Abstract

The invention relates to a chain-type lifting mechanism for carried cargo. The chain-type lifting mechanism comprises a framework, and a platform is arranged in the framework. The chain-type lifting mechanism is characterized in that the framework at the lower part of the platform is provided with a transmission shaft; each of two ends of the drive shaft is provided with a drive sprocket; one side of each drive sprocket is provided with a first fixed seat; each of two ends of the platform is provided with a first reversing sprocket and a second reversing sprocket from bottom to top; the inner side of each of two ends of the top part of the framework is provided with a third reversing sprocket; one side of each third reversing sprocket is provided with a second fixed seat; each of two ends of the inner side of the framework is provided with a chain; one end of each chain is connected with the corresponding first fixed seat, and after being wound on the first reversing sprocket, the drive sprocket, the third reversing sprocket and the second reversing sprocket, the other end of each chain is connected with the corresponding second fixed seat. The lifting mechanism can be adapted to an environment of vibration or shock very well, and is not easy to damage; when the chain-type lifting mechanism is assembled, position adjustment can be realized by adjusting length and end connection tightness of the chains; and the chain-type lifting mechanism has relatively low requirement on manufacturing and assembly accuracy, is relatively low in manufacturing cost, and can be suitable for the automation requirement of small and medium warehousing and on-board warehousing.

Description

technical field [0001] The invention relates to a lifting mechanism, specifically a chain-type cargo-carrying lifting mechanism, which is especially suitable for the vertical displacement operation of goods in an automatic storage system. Background technique [0002] With the development of science and technology, automated storage systems are widely used in storage and transportation and other fields. During the use of the automated storage system, it is necessary to use the transfer machine to load the goods onto the automated shelf, and then use the drive mechanism to drive the drive shaft on the shelf to rotate, thereby driving the conveyor belt or conveyor chain to transport the goods to the corresponding position on the shelf. Since the height of the transfer machine is quite different from the overall height of the automated shelf, it is necessary to use a lifting mechanism to realize the vertical displacement of the goods during the process of using the transfer mac...

Problems solved by technology

However, the meshing structure of the gear and the rack has poor adaptability to the environment, and it is easy to cause damage to the equipment in a vibration or shock environment

At the same time, the meshing of the gear and the rack has high requirements on the manufacturing and assembly accuracy of the transfer machine frame. The climbing column needs to use guide rails to limit the vertical position at the same time to reduce the deformation of the column caused by eccentric loads. The manufacturing cost is high and the economy is poor. , not suitable for the automation needs of small and medium warehousing and on-board warehousing
