Wireless sensing type rectifying system of rail gantry crane

Abstract

The invention relates to a wireless sensing type rectifying system of rail gantry cranes, which is provided with a rectifying processor arranged in a gantry crane electric chamber and a programmable logic controller, and wireless sensor nodes which are respectively arranged at a rigid leg and a flexible leg of the gantry crane and a rail guardrail and for collecting signals. By using the self-positioning function of the wireless sensor nodes, the positions of the rigid leg and the flexible leg on the rail can be directly detected when the gantry crane is in walking, and the position data is transmitted to the rectifying processor, and the precision goal speeds of the rigid leg and the flexible leg can be obtained by appropriate PID algorithm, and a speed value is transmitted to the programmable logic controller and used as an order value of a driving device or an inverter to control the rotation speeds of the rigid leg and the flexible leg cargo motors, thus realizing the automatic rectification of the gantry crane when in walking.

AI Technical Summary

Benefits of technology

This patented technology helps improve the precision at which an armored vehicle can be moved by a tower crane during construction or other operations. It also makes it easier for workers to maintain this equipment without any issues that may affect its performance over time.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance of automated roll-gantzers (RG) during operation without increasing their weight or cost compared to traditional methods like railroad tracks. Current systems require manual adjustment for accurate tracking while maintaining safe operations. Additionally, existing solutions involve complex hardware components requiring frequent replacements overtime, leading to increased costs associated with repair work.
