AI Technical Summary

Technical Problem

The existing stacker crane lubrication mechanism cannot dynamically adjust the amount of lubricating oil sprayed according to the weight of the goods, resulting in insufficient lubrication under heavy load and excessive lubrication under light load, which affects the transmission accuracy and service life. In addition, manual lubrication is inefficient and the effect is unstable.

Method used

The design incorporates elastic components and a lubrication mechanism. By sensing the weight of the goods through the pallet's descent distance, it automatically adjusts the amount of lubricating oil sprayed, ensuring that more oil is sprayed under heavy loads, less under light loads, and a tiny amount is sprayed when unloaded, thus achieving a match between the amount of lubricating oil and the weight of the goods.

Benefits of technology

It effectively reduces wear and operating costs, improves transmission accuracy and equipment life, reduces lubricant waste and pollution, and ensures smooth operation under various load conditions.

Abstract

This application relates to a stacker crane, belonging to the technical field of logistics transfer equipment. The stacker crane includes a column, a load-bearing component, a lifting mechanism, and a lubrication mechanism. The load-bearing component includes a pallet, a support frame, and a first elastic element; the pallet is used to carry goods. The lifting mechanism includes a rack mounted on the column and a gear mounted on the support frame, used to drive the load-bearing component to move up and down along the column. The lubrication mechanism sprays lubricating oil onto the rack. The first elastic element is mounted on the support frame and supports the pallet. The first elastic element can contract under the pressure of the goods carried on the pallet to lower the pallet. The lubrication mechanism increases the amount of lubricating oil sprayed as the pallet lowers; the distance the pallet lowers is proportional to the increase in the amount of lubricating oil sprayed by the lubrication mechanism. The stacker crane provided in this application embodiment can stably and effectively ensure lubrication of the lifting mechanism.
