Description

Sprocket tensioning device of round stacker-reclaimer Technical Field The utility model relates to the technical field of chain wheel tensioning devices, in particular to a chain wheel tensioning device of a round stacker-reclaimer. Background The round stacker-reclaimer is one of the most critical large-scale equipment in cement factories, can simultaneously or respectively complete the stacking and uniformly mixing material taking operation of limestone, and plays a vital role in pre-homogenizing the limestone, stabilizing kiln conditions and ensuring clinker quality. Along with the improvement of environmental protection requirements, in recent years, part of power plants begin to adopt circular closed coal yards for storing coal, stacking and taking materials in the circular coal yards adopt circular stacker-reclaimers, and a chain wheel of the circular stacker-reclaimers needs to use a tensioning device to carry out tensioning treatment on chains when in use; When the chain wheel tensioning device of the existing circular stacker-reclaimer is used, the tightness of a chain can be adjusted through adjusting the position of the tensioning wheel, however, the tensioning wheel is mutually rubbed with the chain when the circular stacker-reclaimer is used, the tensioning wheel is damaged after long-time use, and the tensioning wheel is relatively complicated when being replaced due to inconvenient disassembly and installation treatment, so that the convenience of the circular stacker-reclaimer is reduced when the circular stacker-reclaimer is used, and the chain wheel tensioning device is used for solving the problems.
