Description

Technical Field

[0001] The present invention relates to the field of warehousing technology, and in particular to an adaptive lifting mechanism for a three-dimensional intelligent warehouse. Background Art

[0002] In today's fast-growing logistics and warehousing industry, the three-dimensional intelligent warehouse stands out for its efficient use of space. It cleverly uses the height space to build a multi-layer shelf system, and stores a wide variety of goods in shelves at different heights in an orderly manner. This complex task of picking and placing goods is completed by the lifting mechanism. The existing three-dimensional intelligent warehouse lifting mechanism, its main structure includes a mobile trolley, a belt elevator and a telescopic fork. The mobile trolley slides smoothly on the ground track, driving the belt elevator connected to it to move in a straight line along the predetermined route, and accurately locates the target shelf row; the belt elevator drives the telescopic fork to shuttle up and down to achieve the vertical displacement of the goods. The three work closely together to achieve efficient transfer of goods.

[0003] However, the lifting mechanism of the existing three-dimensional intelligent warehouse has the following disadvantages when in use: 1. The transmission belt of the belt elevator is a key transmission component. In order to ensure that the transmission belt always maintains a moderate tension, it is usually equipped with a tensioning wheel for adjustment. However, most of the existing tensioning wheels rely on regular manual adjustment of the tension degree, which not only requires the operator to have professional skills and rich experience, but also in actual operation, due to the busy warehouse operations, it is very easy to fail to adjust in time due to negligence. Once the transmission belt is too loose, it will lead to poor power transmission, affecting the lifting efficiency, and may even cause serious failures such as slipping and falling of the transmission belt. 1. The telescopic fork of the existing lifting mechanism generally adopts a three-stage design. The third stage and the second stage are linked by a synchronous belt mechanism. However, the synchronous belt will wear out during long-term and high-intensity use. As the wear increases, the meshing accuracy between the synchronous belt and the pulley decreases, thereby affecting the accuracy of picking and placing goods, seriously affecting the accuracy and efficiency of the operation; 2. When the telescopic fork performs the task of transferring goods, the traditional operation method is to directly use the limit lever to hard limit the goods, and then move them to the platform of the telescopic fork. This transfer method can easily cause damage to the bottom of the goods. Summary of the invention
