Description

Technical Field

[0001] The invention relates to the technical field of coal mine equipment, and in particular to a sprocket disassembly and assembly device for a scraper conveyor. Background Art

[0002] Scraper conveyor is an important coal transportation equipment in coal preparation plant. Compared with other conveyors, it has the advantages of small body height, large load capacity, good sealing of the whole machine, and solid body. It is mainly used for coal discharging in stages. The working principle is that the materials in the trough are subjected to the pressure of the scraper chain in the direction of movement and the mass of the materials themselves, and internal friction is generated between the bulk bodies. This internal friction ensures the stable state between the bulk bodies and is greater than the external friction resistance generated by the sliding of the materials in the trough, so that the materials form a continuous and integral material flow and are transported. During use, the scraper conveyor must withstand multiple effects such as pulling, pressing, bending, impact, friction and corrosion, and must have sufficient strength, rigidity, wear resistance and corrosion resistance. However, due to its transportation method that both the materials and the scraper chain slide in the trough, the running resistance and wear are very large, the daily failure rate is high, the maintenance workload is large, the wear parts such as the scraper, chain, head and tail wheel set have a short service life, and the effective working time is short, which restricts the normal production of the coal preparation plant. When the head and tail wheel groups are severely worn, they need to be disassembled, maintained and replaced. The head and tail wheel groups are structures in which the sprocket is installed on the main shaft. The disassembly process usually involves removing the sprocket from the main shaft, which generally requires specific tools and methods, such as using a knocking method. Workers use specific tools to knock the sprocket to ensure safe separation of the connection between the sprocket and the main shaft for subsequent cleaning, maintenance or replacement. This method requires workers to apply force to operate, which is labor-intensive and inefficient.
