Unattended Bucket Wheel Stacker-Reclaimer System (Automatic Stockyard Inventory System)
System Introduction
The Fully Automatic Unattended Bucket Wheel Stacker-Reclaimer System is the essential foundation for building intelligent fuel management, smart ports, and intelligent power plants. Integrating patented technologies in precise positioning, intelligent control, and constant flow control, this system enables fully automated, one-button remote operation. It significantly improves operational efficiency while eliminating health risks associated with harsh, dusty environments. To guarantee maximum reliability, the system is equipped with globally renowned industrial components, including SICK, VEGA, Kübler, and Turck.
System Features
-
Centimeter-Level 3D Positioning: Utilizes industrial-grade GNSS (BeiDou), high-precision encoders, and non-contact calibration devices to achieve precise 3D spatial positioning of the gantry and bucket wheel.
-
Real-Time 3D Stockyard Modeling: High-precision laser scanners continuously map the pile’s contour, establishing a real-time 3D model for automated control and dynamic inventory management.
-
Intelligent One-Button Control: Enables start-stop control with zero manual intervention. Guarantees constant material flow during reclaiming and supports seamless switching between manual and automatic modes.
-
Comprehensive Safety & Anti-Collision: Features redundant signal design and advanced ultrasonic/laser anti-collision devices for both the gantry crane and the cantilever to prevent operational accidents.
-
Centralized High-Definition Monitoring: A single operator can simultaneously oversee multiple stacker-reclaimers via HD video, drastically reducing on-site labor requirements.
Provision of Core Equipment (Hardware)
-
Stockpile & Laser Flow Scanning: Uses German SICK AG laser scanners with motorized protective covers, designed to withstand high dust, heavy vibration, high temperature, and humidity. Realizes 3D stockpile modeling and real-time belt flow detection.
-
Positioning & Angle Detection: Employs Kübler 16-bit high-precision encoders and inclination sensors (encapsulated in 304 stainless steel, accuracy ±0.1°) for rotation and pitch angle detection. Gantry positioning utilizes non-contact Gray bus technology and rotary encoders for continuous, absolute tracking.
-
Anti-Collision & Level Detection: Adopts Turck ultrasonic sensors (with 304 stainless steel secondary encapsulation) for cantilever and gantry anti-collision. VEGA Ps series radar level meters prevent collisions with surrounding objects during automatic stacking.
