Description

Technical Field

[0001] This utility model relates to the field of stacker crane loading platform technology, specifically to a sensor mounting structure for a stacker crane loading platform. Background Technology

[0002] As the modern logistics and warehousing industry rapidly develops towards automation and intelligence, warehouse storage density is constantly increasing, and the requirements for the efficiency of goods entering and leaving the warehouse are becoming increasingly stringent. Stacker cranes, as key storage and retrieval equipment in automated warehouses, require their loading platforms to accurately complete operations such as picking up, transporting, and placing goods. To ensure these operations are performed accurately, sensors need to be strategically placed to monitor the status of each key aspect of the loading platform in real time, such as whether goods are accurately positioned and the platform's position during lifting and extending, thereby meeting the demands of efficient logistics and warehousing operations.

[0003] Currently, photoelectric switches are commonly used for detection. However, photoelectric switch solutions are too limited in function and cannot meet some special customer needs, thus restricting the functionality of the stacker crane. Furthermore, photoelectric switches are easily affected by light, dust, and oil, causing beam scattering and obstruction, which reduces the sensitivity and reliability of the photoelectric switch and affects its normal operation. In certain high-temperature environments, the performance of photoelectric switches may also degrade, affecting the stability of electronic components, leading to reduced detection accuracy, slower response speed, or even malfunction. In low-temperature environments, the material properties of some photoelectric switches may change, affecting their normal operation. This can ultimately compromise the safety of the loading platform. Utility Model Content
