Bucket wheel stacker reclaimer refers to an efficient loading and unloading machinery used for continuous transportation of both stacking and reclaiming materials in large dry bulk cargo yards. It is composed of a belt conveyor arm that can pitch and swing horizontally and its bucket wheel, frame and running mechanism at the front end, the belt can run in both directions, and the material is sent out by the bucket wheel through the conveyor arm when taking the material, and the goods transported by the main conveyor are thrown to the yard through the conveyor arm when stacking.
As an important bulk material handling machinery in ports, electric power, metallurgy and other industries, the operation of bucket wheel stacker reclaimer is currently mainly manual operation, which not only has the defects of poor working environment, low safety, poor accuracy and high operating cost, but also as an important basic terminal machinery, because of the "information island" formed by its manual operation, which greatly hinders the construction and upgrading of intelligent fuel systems and smart ports and smart factories.
Using automatic control technology, Gray bus precise positioning technology, laser 3D scanning technology, image monitoring technology, safety prevention technology and other means, Forward Technology has independently designed and developed an intelligent stack reclaiming unmanned operation system, which integrates mathematical simulation modeling technology and fast laser scanning modeling technology to accurately cut the knife through the coordinate data of the 3D model of the stockpile.
Combined with wireless communication and control technology, the three-dimensional graphics and data of the stockpile are analyzed by using high-precision positioning system, material level radar, anti-collision radar, microwave switch anti-collision system, and remote monitoring system and space anti-collision system.
Combined with the process control strategy of stockyard operation, the automatic stacking and reclaiming execution control program is developed, so as to realize all-weather remote control of stacking and reclaiming, and fully automatic unmanned operation, and realize the standardization and automation of production management and operation of stacking and reclaiming.
The system realizes all-weather, active safety protection of fully automated operation, effectively solves the main problems of high operation requirements, high labor intensity, operator health and safety hazards, low process efficiency, low information means and other major problems in the bulk cargo yard stacking and reclaiming operation, improves the production organization and management level of the yard, realizes the remote automatic control of the all-weather coal yard bucket turbine, effectively solves many problems caused by low manual operation efficiency and harsh environment, and greatly improves the safety and economy of equipment operation.
The system is composed as follows:
Heap scanning acquisition system (LiDAR scanning imaging).
Virtual 3D image reconstruction system (graphics processing algorithm).
Mobile Device Positioning System (Gray Bus Precise Positioning, Angle Sensor).
Anti-collision system (collision between equipment and stockpile, equipment and equipment).
Job rule base system (automatically converted into equipment operation instructions).
Material information tracking management system (material variety, quantity, stacking area, etc.).
Intelligent scheduling system (operation process recommendation, operation instruction generation).
