"This is the GENMA lever luffing portal machine we designed and built for Indonesian customers. Now the technicians are debugging the equipment in the semi-automatic mode of the grab bucket. By testing the automatic fixed-point grabbing and discharging functions of the grab bucket, the operation efficiency of the equipment is improved, and the operation intensity of the driver is reduced at the same time. After the equipment is put into operation, the equipment will provide professional unloading and handling services for the coal supply of the smelter of the customer’s company." RHM debugging engineer introduced.
A few days ago, after the installation of the GENMA lever luffing portal crane Which were designed and built by Nantong Rainbow Heavy Machinery Co., Ltd. (abbreviation: RHM), now entered the equipment debugging stage, and the related functions of the equipment's electronic control system have been further optimizing and debugging.
The electrical system is the power source and nerve center of electrical equipment, which is directly related to the operability and energy saving of the whole machine. The motor of the project equipment adopts full frequency conversion control, and the interlocking function of all programs is realized through the programmable controller. The equipment is supplemented by an automatic unloading control system during the grab bucket operation. Through the fixed-point setting of the grab bucket moving trajectory, the automatic unloading function can be realized, which can effectively improve the working efficiency of the machine and reduce the labor intensity of the driver.
After lifting, lowering, and loading for three times, the equipment has been preliminarily debugged. Kuthu, the equipment maintenance staff of the customer’s company, expressed his satisfaction with the test results of the equipment at this stage, "We are still trying to test further. So far, the loading and unloading operations are very smooth and reliable!"
In addition to the electrical control system, the mechanical structure design of the equipment also affects the overall operation effect of the equipment.
In terms of structural design, the GENMA lever luffing portal crane adopts the portal crane design system independently developed by GENMA. The system integrates the statics and dynamics of the steel structure, moreover, on the basis of the secondary development of the calculation software, it realizes various functions such as the mechanical analysis of the steel structure of the portal machine, the inspection of the movement interference of the boom system, and the calculation of the stability of the whole machine. .
In addition, the equipment has also optimized the design of the connecting rod form, and by adjusting the ratio of the length of the four connecting rods, the portal machine equipment can maintain a stable horizontal displacement of the spreader during the luffing process. Compared with general portal machines, the GENMA portal machine with finite element design is lighter in weight, more reasonable in force, and can operate safely and stably in extreme weather.
Coal is currently the main raw material for thermal power generation. With the development of economy, its transportation demand is also increasing. Up to now, with its excellent industrial design capabilities, Rainbow Heavy Machinery has provided a variety of coal handling and conveying solutions of thermal power plants such as catenary bucket ship unloaders, mobile port cranes, bridge grab ship unloaders and full hydraulic grabs for customers in many industries at home and abroad.
In the future, Rainbow Heavy Machinery will continue to focus on the actual needs of customers, make more efforts in the reliability, applicability and intelligence of equipment products, and provide strong support for the stable loading, unloading and transportation coal and other various bulk materials.
