Description
Technical Field
[0001] This utility model relates to the field of port crane operation control technology, specifically a detection device for the rotation of a port gantry crane. Background Technology
[0002] In container loading and unloading operations at port terminals, gantry cranes (referred to as "gantry cranes") have become the core loading and unloading equipment for small terminals and shallow berths due to their flexible operating performance. Through the coordinated operation of lifting, luffing and slewing mechanisms, gantry cranes can achieve full coverage lifting of containers within a 30-40 meter range of the gantry center, and the slewing mechanism can achieve 360-degree unrestricted rotation, effectively solving the problem of loading and unloading containers in restricted areas. They are widely used in key operations such as unloading, loading and unloading ships and adjusting container doors.
[0003] In the unloading process, the length of the containers in the hold of the berthed vessel is parallel to the coastline. After the gantry crane lifts the containers to the shore, the container's posture changes to be perpendicular to the coastline. It is necessary to accurately detect the position of the gantry crane boom and control the rotating mechanism to adjust the container to a position parallel to the truck before placing it. During the loading process, after the containers lifted from the truck are rotated and moved to the top of the ship by the gantry crane, their posture deviates from the horizontal direction of the coastline. Similarly, the boom position detection signal drives the rotating mechanism to adjust to the target placement position. In the container door operation, in order to ensure that the container door faces outward for security inspection when it is placed into the truck, the gantry crane needs to achieve a precise 180-degree rotation of the boom based on position detection. It can be seen that the position detection accuracy of the gantry crane rotating mechanism directly determines the continuity of the operation process and the loading and unloading efficiency. However, in non-automatic and non-semi-automatic operation scenarios of gantry cranes, traditional rotational position detection methods mainly rely on limit switches and rotary motor encoders, which can no longer meet the core requirements of current automated and semi-automatic operations for accuracy and reliability. Among them, limit switches can only provide trigger-based feedback on the position of preset installation points, which not only detects the position coarsely and cannot continuously reflect the real-time position status of the boom, but also cannot clearly indicate the rotation direction of the gantry crane, making it difficult to adapt to the dynamic position adjustment requirements in complex operations. The rotary motor encoder was originally designed to provide signals for closed-loop control of rotation speed, and its output position count value needs to be processed in double words in the PLC, which increases the complexity of the control program and is prone to cumulative errors during long-term operation, making it impossible to achieve millimeter-level or sub-millimeter-level position detection accuracy. To address this, we propose a gantry crane rotation detection device. Utility Model Content

Then, the limit ring 7 can be slid off to disassemble the contact adapter gear 6 or the detection rotating gear 10. When the encoder needs to be installed or removed, pull the self-locking slide bar 5, causing it to disengage from the self-locking hole 22 while compressing the self-locking spring 21. Press the disassembly pressing slide bar 4 to compress the disassembly reset spring 20, causing the mounting bracket 23 to disengage from the mounting slot 31. Then, the encoder mounting base 3 can be removed to complete the disassembly. During installation, release the disassembly pressing slide bar 4. The disassembly reset spring 20 pushes the mounting bracket 23 into the mounting slot 31.
