Description

Technical Field

[0001] The utility model belongs to the technical field of slag shovel sprockets, and in particular relates to a slag shovel sprocket protection device. Background Art

[0002] Slag remover is a commonly used equipment in power plants and also a key equipment. The sprocket, as the core component of the slag remover, is an important link in the operation of the entire slag remover.

[0003] At present, the sprocket of the existing slag scoop machine is prone to loosening, offset or tilting with the sleeved chain during long-term use, thereby affecting the connection transmission between the sprocket and the chain, and even causing the sprocket and the chain to disengage and be damaged. If the chain and the sprocket cannot engage accurately and smoothly, it will affect the stability and reliability of the equipment operation. At the same time, the offset of the chain is likely to cause the sprocket to become blocked and damaged during operation due to the offset and disengagement of the chain, thereby greatly shortening the service life of the sprocket and also affecting the production efficiency. Therefore, there are deficiencies and cannot meet the user's usage needs. Therefore, it is necessary to further improve it.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a slag shovel sprocket protection device is provided, in order to achieve a more practical purpose. Utility Model Content
