Background
In China, according to the grasped materials, the control of the domestic loader is mainly completed by workers in a traditional cab. In some occasions with severe working environment, even potential safety hazards or inconvenient operation, many unsafe or inconvenient factors exist due to the fact that workers directly drive and control the loader in a cab.
Taking converter steelmaking production as an example, the general procedures of a 300-ton converter for smelting one molten steel each time are as follows: feeding, oxygen blowing smelting, tapping water and discharging steel slag, wherein the smelting period of each furnace is about 45 minutes. After each furnace is smelted, about 270 tons of molten steel and 30 tons of steel slag are respectively poured into a molten steel tank trolley and a slag ladle trolley below the converter, and the molten steel tank trolley and the slag ladle trolley are transported to different directions. In the links of feeding, smelting, molten steel discharging, steel slag discharging and the like, splashes and fallen objects fall under the converter, so that the underground tunnel and the trolley track under the converter are covered over time, the material receiving and the material receiving of the trolley are influenced, and the normal operation of converter steelmaking is finally influenced, therefore, the underground tunnel and the track under the converter must be cleaned in time, and the cleaning time of each time needs 30-45 minutes. Because the cleaning operation environment still has potential safety hazards such as high temperature, high dust, falling objects and the like, and the potential safety hazards are defined as foreseeable potential safety hazards and must be eliminated. When an operator directly drives a loader to operate under a converter, the converter must stop steelmaking in order to ensure the personal safety of the operator, so that the improvement of steelmaking yield is restricted. The potential safety hazards exist in various large steel mills, and similar potential hazards are transferred by outsourcing service or cooperative production modes adopted by many steel mills at present, but the potential safety hazards exist all the time, the problems cannot be fundamentally solved, and the potential safety hazards are replaced by new technologies and new equipment in time.
The remote control engineering machine developed by the inventor is mainly used for matching with the production of iron and steel smelting enterprises in iron and steel making. The remote control engineering machinery is produced under the operating environment, although the remote control operating system is applied to the engineering machinery and belongs to the starting stage, the use of the remote control engineering machinery can change the production process of blowing out and slag removing in converter production, realize the continuous production process of blowing out and slag removing in converter steelmaking, and improve the production efficiency while ensuring the safe production. Due to the successful application of the remote control technology, the technology can be gradually expanded to other models and other industries in the future.
To realize remote control, the configuration of the carrier must be comprehensively known, and the support of relevant knowledge and technology such as electric appliances, hydraulic pressure, pneumatics, machinery and the like is provided. In view of the above-mentioned drawbacks of the conventional loader control method, the present inventors have developed a loader capable of being remotely controlled based on practical experience and professional knowledge that has been enriched over the years in designing and manufacturing such products. The inventor continuously researches, tests and improves to create the utility model.
