Description

[0001] The utility model relates to the technical field of stackers, in particular to an auxiliary guide wheel of a cargo platform on a super-high stacker. Background Art

[0002] The automated high-bay warehouse is a new concept in logistics warehousing. It is a warehouse that uses high-rise high-bay shelves to store materials, is controlled and managed by computers, and uses automatically controlled stackers to store and retrieve materials. The stacker is an important handling equipment in automated warehousing equipment. The loading platform on the stacker is mainly driven by a lifting motor, and the lifting wheel group is used to contact the column guide rail for stable lifting operation.

[0003] The existing super-high stacker columns are too long, and deformation of the columns and lifting guide rails is inevitable during the manufacturing and application process. Due to the characteristics of the double-column stacker, only one side of the guide wheel on the cargo platform can hold the lifting guide rail; therefore, during the super-high lifting operation, the lifting guide wheel of the cargo platform may deviate from the track and derail; therefore, it does not meet the existing needs. In this regard, we propose an auxiliary guide wheel for the cargo platform on the super-high stacker. Utility Model Content
