Single beam bridge cranes and grabs (electromagnetic cranes) are widely used in the mining industry. The existing operation mode is manual operation, the work of grasping waste is monotonous, the operation activities are simple and repetitive, the labor efficiency of personnel is not high, and it is easy to be fatigued and cause safety accidents. In order to improve the labor efficiency of personnel and adapt to the requirements of intelligent manufacturing in the steel industry, it is necessary to transform such simple and repetitive operations to realize automatic grasping of bulk materials, automatic matching of quantities, and automatic weight statistics.
Through unmanned transformation, it has the functions of automatic slag grabbing (bulk material), precise positioning, anti-swing, automatic avoidance, automatic weighing, remote control, automatic feeding and other functions. The shape, position, center of gravity, etc. of the transported object can be identified by scanning. The equipment runs smoothly, the working curve is smooth, and the service life is prolonged. Combined with the advanced warehouse management system (WMS), the intelligent management and unmanned operation of the garage management system are realized. Effectively reduce operation and maintenance costs and labor costs.
On the basis of the existing crane, the transformation is carried out to realize the automatic completion of the unmanned crane system grab the bulk material from the slag pool to the stockyard, or grab the bulk material from the stockyard to the transport vehicle.
Real-time detection of the three-dimensional position of the crane hook, monitoring the running state of the crane, with anti-sway function, the overall anti-sway scheme can effectively eliminate 90% of the swing, when the grab bucket is closed, the four wire rope maintain uniform force at all times.
Visually track the status of the hook online, and judge the position of the hook in real time, so that the control system traverses the entire swirl well, realizes the grabbing at the edge, and has the function of protecting the grab bucket and the wall;
Display work instructions on the road and monitor the execution of work instructions;
The avoidance of the prohibited area is based on the target position of the operation instruction and the current position of the crane, combined with the material position data of the warehouse, and automatically calculates the optimal path for the crane to complete the avoidance of the prohibited area.
The unmanned driving is designed according to the double insurance principle of “double signal, double detection and double correction”. It has functions such as automatic cruise, crane centralized control, remote monitoring, video linkage, automatic deviation correction, and safe path, etc., to achieve “unmanned operation, being monitored”. Communication fault detection between crane-mounted PLC and management station. When there is a communication fault, the equipment will automatically stop at the current position to ensure safety.
When the material is discharged continuously, it has the functions of transferring material, stacking material, and automatic loading. The size of the crane is automatically recognized, and the loading amount is automatically calculated.
The unmanned crane transformation is suitable for the scene of sludge, ore powder, coal, coke, scrap steel, waste residue, garbage and other bulk materials.
Unmanned crane system for slag grabbing in iron-smelting slag pool;
Unmanned slag grabbing crane system for steelmaking and rolling swirl wells
Unmanned crane system in scrap steel raw material area;
Unmanned crane system for slag fishing in sewage pool;
Unmanned intelligent system for crane in concentrate silo (dry coal shed).
The equipment and technology selected by the system represent the advanced and mainstream products and technologies in the world today, and are widely used in many fields.
The on-board and ground equipment transmits data through wireless local area network. The communication complies with the IEEE 802.11b/g standard, and the maximum transmission rate can reach 54Mbps. In addition, the equipment has good wireless coverage and receiving performance, which ensures the real-time and rapidity of data transmission.
Using Gray bus detection technology, its absolute address information is true and reliable, there will be no code error, no accumulated error
The equipment selected by the system is specially designed for the industrial site environment. Using mature sensors, fixed-point calibration and PLC system programming. It has high anti-electromagnetic interference, anti-vibration, high and low temperature resistance, dust-proof and waterproof performance, 365*24 hours of continuous operation, meet its use in steel and other enterprises.
The crane grab only works in the designated area. If there are cars or people in the area, the program will set a prohibited area. The crane small car in the prohibited area will stop working and the grab will be raised to the limit position; fire safety in the storage area: real-time automatic Continuously monitor the temperature of coal piles in the reservoir area and set up flame and CO monitoring devices to give early warning of abnormality; anti-collision technology;
Through the planning of the driving route, the invalid distance is reduced; the management efficiency is improved, and the efficiency is improved by the planning of the driving working mode and the path.
Using advanced software platform architecture, it can intelligently detect abnormal situations such as grab rope knots, inverted buckets, and wire rope out of troughs; set up wire rope group tension detection and automatic lubrication systems to intelligently detect blockage at the bin mouth and process coal breaking; It can judge the material blockage in the bin and alarm; it can judge that the material pile is frozen and automatically avoid the freezing area.
