Description

Technical Field

[0001] The present invention relates to the technical field of roadheaders, and particularly to a small and medium-sized intelligent roadheader. Background Technique

[0002] During the application process, the roadheader always works at the forefront of the roadway. The working conditions are harsh and harmful to the physical health of workers. Due to many potential safety hazards caused by poor visibility, water, electricity, falling objects, etc., in accordance with the latest national requirements, coal mines should be equipped with intelligent roadheaders of corresponding standards to ensure the improvement of the safety factor underground and the intelligent level of the coal mining industry. Therefore, in recent years, each coal mine has begun to be equipped with intelligent roadheaders.

[0003] At present, the working mode of roadheaders is generally manual operation, which does not have the functions of multi-functional operations such as hole detection and support at the same time, cannot realize intelligent operation, has low work continuity, low work efficiency, high labor intensity of workers, and poses a certain threat to the personal safety of workers. Most of the existing intelligent tunneling equipment on the market is only for large coal mines. Although the degree of intelligence is relatively high, the costs are generally high. Small and medium-sized coal mines cannot afford the high costs, and most of them are large in size. Due to size limitations, the roadheaders cannot be disassembled and lowered into the wells in small and medium-sized coal mine roadways, which cannot meet the current market demand. Due to the above problems, a small and medium-sized intelligent roadheader is specifically introduced. Summary of the Invention
