Abstract
Description
Technical Field
[0001] The utility model relates to the field of machinery manufacturing and automation, and particularly relates to a double-rack elevator. Background Art
[0002] Among the existing four-way vehicle elevators, the elevators that are more commonly used are those that use the chain lifting method. In this method, there is a relatively large gap between the chains. When heavy goods enter the elevator, the car of the elevator may sink, which may cause the goods to get stuck at the entrance and exit. In addition, the chain elevator needs to install an additional line at the entrance and exit for discharging goods. The chain elevator can only transport the goods to the shelf opening and then be transported out of the elevator by the conveyor line, resulting in slow operation efficiency and inability to transfer the four-way vehicle on each layer of the shelf. In this case, it is necessary to place a trolley on each layer, which greatly increases the cost, and the positioning accuracy is not high. The maintenance of the motor also requires climbing to the top for maintenance, increasing the maintenance difficulty. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a double-rack elevator. By adopting the gear-rack transmission method for lifting, it has good meshing performance, small gap, accurate running positioning, and convenient maintenance. It can realize the simultaneous layer-changing operation of the trolley and the goods, improving the operation efficiency.
