Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gate plate sensing devices, in particular to a gate plate sensing device for an automatic loading system. Background Art
[0002] Since its commissioning, the rapid loading station has handled over 15 million tons of clean coal annually. To ensure loading quality and accuracy, the automatic loading system's gates frequently operate, causing severe wear on the gates and bearings, leading to gate sinking. When the front end of the gate sinks 3mm, the gate limit switch signal is lost, impacting normal loading. Prior to the renovation, this issue was addressed by replacing the gates and adjusting the height of the limit switches and signal sensing magnets, which incurred additional costs for purchasing gates.
[0003] Due to the limitations of the dust cover, the original limit switch could not be adjusted downward and could only move horizontally. When the gate plate sank due to wear, the switch signal could not be fed back to the PLC. The modified limit switch was fixed to the bracket on the inside of the gate frame inside the dust cover, and a corresponding signal sensing metal plate was welded to the edge of the gate plate. The signal sensing plate moves with the opening and closing of the gate plate. When the limit switch receives the sensing plate signal, it outputs high and low level feedback to the PLC. The modified switch can move up and down, forward and backward, and the position signal sensing is sensitive. Utility Model Content
